Title: Manufacture of semiconductor device
Inventor: YAMAZAKI SHUNPEI
IPC: H01L27/108
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To easily form capacitors, etc., with excellent characteristic only through a low-temperature process by forming a nitrate layer on an electrode through a sputtering method using a gas of specific concentration of nitrogen. SOLUTION: In the method for forming metallic nitride film of resistors such as silicon nitride dielectric of aluminum nitride, titanium nitride, tantalum nitride, etc., a nitride layer as an insulation film or a resistance film covering electrodes is formed by a sputtering method using a gas of at least 75% of nitrogen concentration. In the case where a high-purity nitrogen evaporated from liquid nitrogen in particular, unnecessary silicon or atom to be taken into the nitride layer does not exist, and accordingly a nitride layer that has no pin-hole and inductive damage and less variation of dielectric strength can be formed on the electrode. Further, a gas containing halogen elements of 0.2-20 vol.% is mixed to a gas with a concentration of nitrogen of 75% or more at the same time, so neutralization of alkali ions introduced unintendedly to the nitride layer can be promoted at the same time.

Filed: 1978-10-03
Abstract: PURPOSE: To obtain an electrically coloring element device which can make various color displays and which has an improved displaying contrast, by using a specially fixed metal oxide as its electrically coloring layer.  
     CONSTITUTION: In an electrically coloring display device which is composed of transparent electrode layer 2, glass substrate 1 on which electrically coloring layer 4 is installed, glass substrate 1 on which opposed electrode layer 3 is installed, glass spacer 5 which connects the above mentioned components, and electrolyte solution 6 enclosed into a space thus formed, the above-mentioned electrically coloring layer 4 is replaced with  a metal oxide which has a low oxidation number and colors under oxidized condition. This electrically coloring display device is manufactured in this method. For example, when V 2 O 3  is used to form electrically coloring layer 4 and a voltage of about 5V is applied across opposed electrode layer 2 (positive side) and opposed electrode layer 4 (negative side), the above mentioned coloring layer becomes orange in color. When Cu 2 O, instead of V 2 O 3 , is used it becomes black (at about 7V), and when a compound composed of 9 parts of V 2 O 3  and 1 parts of WO 3  is used yellow color (at about 2V) can be displayed.

Title: Auxiliary cooler for air-cooled two-cycle engine
Inventor: YAMAMOTO MASAHIRO
IPC: F02B75/02
Filed: 1979-09-20
Abstract: PURPOSE: To prevent overheat of an engine by providing a valve which is opened to supply the engine with a cooling water when a temperature of a cylinder head is increased over a specific value.  
     CONSTITUTION: When an engine is under a light load, a variation of pressure in a crankcase is low so a diaphragm 5 is shifted a little. Thereby, the discharged amount of a pump (a) is minimized. A greater load provides a greater shifting of the diaphragm 5 so the discharged amount of the pump (a) is increased. When the temperature of the engine, that is of a combustion chamber (d), rises up to a specific temperature or more, a bimetal 17 detects the temperature and is subjected to distortion. Associated with distortion, a valve (b) is opened to supply a nozzle (c) with a cooling water.

Title: Device for transporting slab
Inventor: TAURA RYOJI
IPC: B21B1/02
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To transport a slab while suppressing flaws which are generated on the surface of the slab by providing clamping means for clamping the slab from the up and down directions and moving means for moving by sliding the slab in the horizontal direction. SOLUTION: The slab 1 is clamped with a planar transporting truck 2 and freely rotatable roller 4, the surface of the transporting truck 2 is brought into contact with the surface of the slab 1, the transporting truck 2 is moved integrally with the slab 1 along the direction of the line and the slab 1 is transported while rotating the roller 4 following the movement of the stab 1. Then, the slab 1 and the transporting truck 2 become difficult to slide and slip flaws become difficult to generate on the surface of the slab 1. Because the contact area between the slab 1 and the transporting truck 2 is larger, contact surface pressure is suppressed. So, not only possibility that impression is left on the slab 1 is smaller but the degree of the slip flaw is reduced even if mutual surfaces are slipped by insufficient clamping.

Filed: 1981-08-06
Abstract: PURPOSE:To measure the horizontal degree of the ram surface accurately and simply, by detecting and numerically displaying the interval between the base and the ram in the machine tool as a voltage value. CONSTITUTION:A potentiometer 11 is adjusted at a reference position, and the position of the ram of the machine tool is determined. Then sensors 12-11 for the measuring positions are brought to the reference position where the potentiometer 11 is set and the zero adjustment is performed.

The result is digitized by an A/D converter 31. A display 41 displays a sign and the level. When the potentiometer 12 is set between the ram and the base at the measuring position after the zero adjustment, the numerical value indicating whether it is higher or lower than the reference position is displayed.
