Abstract: PROBLEM TO BE SOLVED: To enable an SRAM to be formed of a less number of wiring layers, by a method wherein a first and a second load devices are composed of common contacts which connect a power supply wiring to a drain region and a gate electrode. SOLUTION: A first and a second load devices are composed of common contacts 105a and 105b which connect a power supply wiring 106 that feeds a power supply to the drain regions of a first and a second drive gate field effect transistor to the drain regions and the gate electrodes of a first and a second drive gate field effect transistor. Therefore, grounding wirings 108a and 108b used for grounding the source regions of the first and second drive gate field effect transistor and the power supply wiring 106 can be formed of the same conductive layer. By this setup, SRAM cells can be formed of a less number of wiring layers without deteriorating its operating characteristics.

Title: Thin type battery
Inventor: SATO TOSHIO
IPC: B42D15/10
Filed: 1990-09-29
Abstract: PURPOSE:To prevent data distortion generated on a magnetic recording medium arranged on the surface and the like by increasing the magnetic resistance of an electrode terminal plate, as a magnetic circuit, and by determining the coercive force on the surface end part as no more than 300e. CONSTITUTION:A negative electrode terminal plate 7 is formed out of rolled aluminum, and a negative electrode lithium 6 clad thereon is formed out of amalgam (alloy) of lithium and aluminum. A plate-shaped positive electrode complex agent 4 formed out of manganese dioxide is arranged on a separator 2 on the negative electrode lithium 6, which is covered with a positive electrode terminal plate 5 which is a current collector of positive electrodes. To inhibit residual magnetism by forming the current collector of battery out of non- magnetic metallic material, the coercive force on the end part, in particular, is determined as no more than 300e, so as to eliminate magnetization on the surface of the current collector. Even when an IC card and the like that forms a magnetic stripe on the surface, is exposed to a strong magnetic field, the distortion of a magnetic data of the magnetic stripe due to the magnetization of a stored thin type battery can thus be prevented.

IPC: C23C8/26
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To manufacture a die for die casting easy in machining and having the necessary impact strength and further, excellent in heat check resistance, etc. SOLUTION: This die for die casting is formed with a tool steel for hot working, having the hardness of HRC30-HRC45, the surface is applied with a nitriding treatment and where a nitriding hardened layer having <=50 μm thickness of and Hv 600-Hv 900 surface hardness is formed. Therefore, the hardness of the die is lower than that of a die in conventional technique, the cutting is easily executed and the wording at the time of finishing the die after heat treatment is facilitated. Further, since the tool steel for hot working has high tenacity, the necessary impact strength can be secured. Further, since the hardness of the die surface is held to Hv 600-Hv 900 with the nitriding treatment, the heat check resistant can be improved.  Furthermore, since the thickness of the nitriding hardened layer is <=50 μm, the tenacity on the die surface is not lowered so much and the lowering of the impact strength can be prevented.

Title: Simultaneously measuring apparatus for changes in size and weight
Inventor: SATO YASUHIRO
IPC: G01G19/52
Filed: 1985-11-22
Abstract: PURPOSE:To enable simultaneous measurement of changes in size and weight of a cement-based porous material, by combining a non-contact type displacement gauge and a loadcell type weight measuring device. CONSTITUTION:An object to be measured is a plate sample 1 of cement-based porous material and is topped with a metallic cap 2. An eddy current displacement sensor 3 is arranged slightly separated from the cap 2 and an electric signal from the sensor 3 is taken out via a cable 4. The eddy current generated between the sensor 3 and the cap 2 varies in the intensity with the size of the clearance. The changes in the size of the sample 1 can be measured by capturing the variation as displacement. A loadcell 5 is arranged below a holder 5a of the sample 1 to measure changes in the weight of the sample 1. An electric signal from the loadcell 5 is taken out via a cable 6. It should be noted that a displacement of the loadcell 5 itself if small for weight change, much smaller than variation in the size of the sample 1. Thus, the displacement of the loadcell 5 itself can be ignored, in no way affecting the measurement of changes in the size.
