家居裝修的問題

七月 30, 2007

1.材料的選擇,工人給您的材料中是否會出現價格不同的材料,如果有,一定要注意,其中一些高價材料是做門體使用的。

2.板材的使用中,如果會出現門的使用,一定要記得穿筋,這樣可以防止板材的變形。

3.對於吊頂等一些使用木方的地方使用前最好先刷清漆,這樣可以防止木方的老化和氣味的擴散,也可以防蟲。

4.一定的板材浪費是可以的,不要把所有板材都做拼裝,會影響您的使用期限的。

5.對於使用線條的時候注意色彩的一致性,有的施工人員會告訴您刷完漆就一樣了,可是有些木色是不可能一樣的,再者不要找完全一樣的。

 6.木工在工作中可能會向您提出一些合理的建議,如果您認為合適也可以聽取的,因為木工天天接觸這些東西,對於人體工程學的掌握多少要強於業主的。

 7.打固定釘時注意讓木工看著些,因為一些不是太厚的東西木工很有可能給打過了。

8. 可以找好的家居裝修公司幫忙。

電容的鑑別

七月 26, 2007

1. 按照品牌來區分:主板電容主要分為台系和日系兩種,日系品牌有:NICHICON,RUBYCON(紅寶石)、KZG、SANYO(三洋)、 PANASONIC(松下)、FUJITSU(富士通)等;台系品牌有:TAICON、G-LUXCON、CAPXON、OST、GSC、RLS等品牌。一般日系電容要比台系電容更為經久耐用,不過成本也略微高一點點。

2.從指標上區別:電容電壓的範圍非常重要,可以在電容上看到”+、-”的字樣,這是電容電壓的承受範圍,這個數值越小電容則越好。

3. 看電容的容量:一般主板都是採用大量小容量電容,整齊的拍部在CPU附近,也有個別主板廠商使用幾個大容量電容。其實兩者的成本相差無幾,目的都是提供足夠的電容容量也確保CPU供電的穩定。總之,一塊性能出眾的主板必定擁有高品質的電容為其保駕護航。

Finally found MP which admires 421

七月 25, 2007

Looked for this in 2006 F1 the Kimi seat to harness has already lookedfor a long time, last year F1 competition time has bought on the plan,when this year product. Today finally found in the Jinling road modelshop. During experiences difficultly innumerable: Wan Tiguan life halldoes not have, to be on-line had not found (found does not dare tobuy), afterwards heard the Hong Kong Exchange, the Pacific Ocean abovehave hotwheel, found the brand actually not to have this section.Today found also is final, was lucky, ha-ha. In the shop has 1:18HotWheel, but felt works is not that fine as if. Then has transferredquite several in the shop, finally in cabinet small F1, found thissmall very many Minichamps 1:43, originally also thinks this kind ofcar not our place, as soon as looked the price is equally matched withthat 1:18 large cart, therefore carefully has looked for, had reallyfound only this

Choro-Q model vehicle

As soon as went on the market in Taiwan creates the stir Choro-Q toreturn to the manpower-operated vehicles to have to promote the newproduct, so-called Choro-Q returned to the manpower-operated vehiclesactually is one kind of quite simple toy, single-handed returned themanpower-operated vehicles to press is towing pulls, after letsloose could go forward. But because besides the circle fat lovable,the design fine, the color is fresh , the modelling draws upreally, therefore lets many people be unable to put down.

In world smallest commercialized human form robot birth

七月 23, 2007

Produces distorts Japanese toy manufacturer Tomy whichJin’gang is famous on 20th to announce that, this company plans onOctober 25 the official investment market robot toy by the Guinnessheadquarters had been recognized is “the world smallestcommercialization human form robot”.

It is reported, this section named “O m n i b o t 17 mu i – S O B O T”the robot toy although only has 16.5 centimeter high, actually may besame like the person walks, and can speak 180 phrases, meets200 many kinds of movements. Under the controller operation, the robotmay according to the procedure which arranges make each kind ofcombination movement.

Electrical Properties knowledge

Rated upper limit temperature, usable upper limit temperature, and derating ratio of usable upper limit temperature . e.g. sungho product

  The Polyester(PET) capacitor is relatively high in dissipation factor(tan δ), and when used at high frequency, then the self heating temperature is increased. Use within the self heating temperature is if 10℃ or less, and the capacitor surface temperature not exceeding the rated upper limit temperature. When using at high frequency, there is a risk of thermal runaway(smoke, fire) due to self heat generation in the capacitor. Derate the rated voltage according to the example below. Therefore, the rated voltage at 150Vrms at commercial frequency. (It is necessary to derate the rated voltage until the self heating temperature rising of the capacitor is below the specified value.)

 
NOTES(1) Use the peak value(Vo-p) of the pulse voltage applied to both ends of the capacitor within the DC rated voltage.
(2) When using at high frequency it may lead to breakdown due to withstand voltage deterikoration by self heat generation. Therefore, measure the self heating temperature rising value of the capacitor and make sure it must be used within the specified limit.

What does the electric capacity fall presses in the electric circuitthe bleeder function is?

七月 20, 2007

Falls in the electric capacity presses in the electric circuit, isfalling presses the electric capacity the beginnings and ends parallelto have a bleeder, asked what this bleeder the function is?

When the dizzy wave is shut off when the biggest peak value time, onthe electric capacity surviving electric charge is unable to release,can for a long time exist. When service if the human body contacts the electric capacity the metal partially, can have intensely receives anelectric shock possibly, but the resistance existence, can the capacitor charge which survives fall, thus the guarantor,machine is safe.

Connects in many electric capacities in the electric circuit, in theelectric capacity beginnings and ends parallel resistance, thisresistance resistance number generally all is often bigger,approximately about 100K. This resistance is not the bleeder, but isthe balancing resistor. Is balances the electric capacity beginningsand ends voltage to use. After this resistor, may prevent theindividual electric capacity beginnings and ends damage.

What vehicle mold comparison has the collection value?

七月 20, 2007

The vehicle mold you certainly must buy limit the quantity theversion, moreover cannot buy too slightly, otherwise too was smallcould not have manifested the real vehicle connotation, the collectionvalue has also lowered Then you buy Che Mu works certainly must begood! ! The vehicle type certainly wants the world well-known –  Tomica,

Simulation Che Mu is completely defers to the real vehicle theproportion to carry on the compression, for instance 1:18, it isdefers to the real vehicle the original automobile body size exceptby, Che Mu vehicle door which 18 comes and , the reserve boxall is may open, the inside steering wheel also may rotate the wheel!! ! ! ! ! Then you must look produces Che Mu the brand, now the bestbrand is AA , he 1:18 Che Muda outline 500-800 Yuan 1, but isnot limits the quantity, liked promotes the blue abundantalready Nepali whole world to limit the quantity 1,000 vehicles molds,the selling price 3,900 1! ! ! Such only then has the collectionvalue, you thought, entire Earth Ye! Only then 1,000 . Tamiya car model.
