Title: Manufacture of semiconductor device
Inventor: DEGUCHI KEIJI
IPC: H01L29/43
Filed: 1989-03-23
Abstract: PURPOSE:To prevent a change in a composition by abnormal oxidation of a tungsten silicide film even after a thermal process and to prevent a film from being stripped off by a method wherein, after the tungsten silicide layer has been formed, N<+> ions are implanted. CONSTITUTION:A polycrystalline silicon film 5 and a tungsten silicide film 6 are laminated one after another on a semiconductor substrate 1; after that, N<+> ions are implanted into the tungsten silicide film 6. When the N<+> ions are implanted in this manner, it is promoted that the tungsten silicide layer 6 is made amorphous, sudden crystallization during a thermal process is suppressed and a particle diameter can be made small. Accordingly, it is possible to suppress an increase in a stress of the tungsten silicide layer 6, and a close-contact property to the substratum polycrystalline silicon film 5 can be maintained. In addition, a surface layer of the tungsten silicide film 6 is nitrified; oxidation of tungsten is suppressed; formation of WO2 and WO3 is prevented. Thereby, it is possible to prevent abnormal oxidation and a film exfoliation phenomenon which are caused when the N<+> ions are not implanted.

Title: Foaming-prevention device for container liquid surface
Inventor: FUJINO YOSHIHISA
IPC: B65D90/42
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To restrict foaming on a liquid surface in a container, measure the liquid surface sufficiently accurately by a conventional liquid-surface- measurement using a pressure difference, and reduce cost without extra equipment by floating onto the liquid surface a float whose area is slightly smaller than the area of the liquid surface in the container used for purifying gas passing through a spray. SOLUTION: The lower part of the cylindrical part of an absorption tower 1 is filled with a magnesium hydroxide solution 7, and, on its liquid surface, a float 10 in the form of a flat plate is disposed almost on the entire surface, leaving its periphery. The float 10 floats on the water solution and is made of a material which is not damaged by a desulfurizing agent such as the magnesium hydroxide. Therefore, the droplets of the sprayed liquid do not strike against the liquid surface directly but strike against the upper surface of the float 10, to prevent catch of air into the liquid by the contact of the droplets of the sprayed liquid with the liquid, which causes the occurrence of foam.  Also, pressure by the weight of the float 10 itself and downward pressing force by the strike of the sprayed liquid against the upper surface of the float 10 acts, foam can be eliminated effectively.

Title: Device for illuminating display panel
Inventor: GOKOUDA SATORU
IPC: B60Q3/04
Filed: 1985-04-10
Abstract: PURPOSE:To uniformly illuminate the whole of a display panel by providing a first reflector in front of a bulb leaving a gap for through light, and a second reflector on the side of said bulb. CONSTITUTION:When a bulb 4 is lit, the greater part of direct light of the illuminating light of the bulb 4, is intercepted by the back of a first reflector 12, but light which passed through its slit type gap 12d is gradually diffused, uniformly illuminating the center part of a display panel 1. On the other hand, the direct light which is intercepted by the back of the reflector 12, is reflected to second reflectors 13 and 14 and, further, due to the reflection of the reflectors 13, 14, uniformly illuminates the whole periphery of the display panel 1. That is, the center part of the display panel 1 is irradiated with a weaker light since the greater part of the direct light is intercepted by the back of the reflector 12, while the quantity of light which radiates near both corners is increased with the reflected light from the reflectors 13, 14 being added to the direct light of the bulb 4, thereby, uniformly illuminating the whole of the display panel.

Filed: 1983-04-28
Abstract: PURPOSE:To improve the operability of a cooking device by enabling to previously register the weights of several types of vessels, and eliminating the detection of the weights of the vessels in case of cooking. CONSTITUTION:A user gathers vessels to be used normally to set them one by one on a rack 11, detects by a weight sensor 12 the weights of the vessels while corresponding to the display pattern of a display unit 4 (to the similarity of the shape) by using a condition input key 5, and sequentially stores them in an RAM17 of a microcomputer 16. In case of cooking, when a cooking operation is started by the key 5, the microcomputer sequentially displays the display pattern of the vessels on the display unit 4, and requests the user for the selecting operation of the vessel. If the selecting operation is executed by the key 5 when the vessel 13 is similar in shape, the microcomputer 16 reads out the weight data of the vessel 13 from the RAM17 to subtract it from the weight information loaded for the weight data, thereby detecting the weight of the food only.
