Inventor: HORI ATSUSHI
IPC: H01L21/336
Filed: 1990-10-08
Abstract: PURPOSE:To easily conduct etching on a second semiconductor film without requiring a specific etchant by a method wherein a buffer film is formed after a lower layer of first semiconductor film, which becomes a gate electrode, and an upper layer of second semiconductor film, which becomes a gate electrode, are formed on the buffer layer. CONSTITUTION:A first insulating film 101, an N-type polysilicon film 104 are successively formed on a P-type silicon single crystal semiconductor substrate 100. Then, a polysilicon pattern 104A is formed by etching the polysilicon film 104. Subsequently, the first semiconductor film 102 is exposed by conducting wet etching. Then, an N-type polysilicon film 10 and a silicon film 109 are deposited. Subsequently, spacers 109A and 109B are left by conducting anisotropic dry etching. Polysilicon films 102 and 110 are etched, and polysilicon patterns 102A and 110A are formed. Then, using the polysilicon pattern 104A and the spacers 109A and 109B as a mask, arsenic ions are implanted into the P-type silicon single crystal semiconductor substrate 100, and a high density N-type semiconductor regions 107A and 107B are formed.

Title: Semiconductor integrated circuit device
Inventor: TAKI YOICHIRO
IPC: H03K19/082
Filed: 1984-12-21
Abstract: PURPOSE:To prevent the setting value of the 2nd signal line voltage even when a noise below a low potential power supply voltage is superimposed on an output by adding a transistor turned on/off by a signal on the 1st signal line line and a transistor (TR) whose emitter is connected to a low potential power supply. CONSTITUTION:The 2nd signal line 15 is connected to a collector of an SBD npn TR16 turned on/off together with an SBD npn TR7. The collector potential of the TR16 depends on a voltage at a low potential power supply terminal 2 by an npn TR17. Even when a noise below the low potential power supply voltage is superimposed on an output terminal 3, the level of the signal line 15 is not affected at all. Thus, the setting value of the signal line voltage is not fluctuated.

Inventor: NIKO KIYOSUKE
IPC: G03G9/113
Filed: 1988-10-27
Abstract: PURPOSE:To impart stable electrostatic chargeability to a toner and to improve the durability of the carrier by subjecting the carrier surface to extremely thin metallic coating. CONSTITUTION:The surface of the carrier for electrophotographic development is subjected to uniform plating. The plating is preferably executed by an electroless plating method and the plating thickness is preferably set at 0.001 to 0.1mum. Plating species of metals, semimetals or the alloys thereof are utilizable for the plating species. Particularly the electroless plating essentially consisting of an Ni-P system, i.e. nickel sulfate, sodium hypophosphite and complexing agent is suitable for electroless plating as this plating is relatively excellent in the properties and characteristics of the plating film and in addition, the safety, controllability, economy, etc., of the plating bath are good. The stable electrostatic chargeability is imparted to the toner in this way and the durability and stability of the carrier are improved.

Title: Refrigerator
Inventor: YAMADA TETSURO
IPC: F25D17/08
Filed: 1988-10-26
Abstract: PURPOSE:To contrive the even cooling of the inside of a cooling chamber by a method wherein a cold air outflow position switching mechanism is switched so that cold air is made to flow out of a cold air outlet port corresponding to a temperature sensor showing a higher detecting temperature when the detecting temperatures of more than two sets of temperature sensors are higher than a predetermined cooling starting temperature. CONSTITUTION:The detecting temperatures of temperature sensors 11, 12 for upper and lower stages are judged whether they are higher than a predetermined cooling starting temperature Tu or not and when it is judged YES, an upper stage in a refrigerating chamber 3 is judged whether it is being cooled or not (whether cold air is made to flow out of the cold air outlet port 8 of the upper stage or not). When the same temperatures are judged that both of the temperatures in the upper and lower stages are higher than the cooling starting temperature Tu, the detecting temperatures of both of the temperature sensors 11, 12 are compared and when the detecting temperature of the upper stage is higher than the same of the lower stage, a 'flag showing the detecting temperature is higher than the cooling starting temperature' and 'flag showing that the upper stage is being cooled' are reset and cold air is made to flow out of the cold air outlet port 8 of the upper stage. The operation is effected by starting the motor 14 of a cold air outflow position switching mechanism 13 to pivot a cam 15 whereby a movable opening body 18 is moved to an upper stage cooling position.

Title: Mechanism for varying constant of suspension spring
Inventor: HAMANO KAZUO
IPC: B60G17/027
Filed: 1988-10-27
Abstract: PURPOSE:To vary a suspension spring constant extremely and improve a comfortable ride and steering stability by combining a suspension spring with a torsion bar and also switching the action/no-action of the torsion bar by a hydraulic cylinder. CONSTITUTION:A suspension spring constant is determined by the combination of a suspension spring 5 on a damper 4 with a torsion bar 6. Now, when a pump 18 is driven and an operation oil is press-fed to the oil chamber S of a cylinder 12 in a hydraulic cylinder device 10, a free piston 14 is moved to the left side shown in the picture against a return spring 15 and a piston 13 is pushed into the end part of the cylinder 12 and an arm 9 is held at the appropriate position. Consequently, as an arm 8 mounted on a wheel 2 is rotated by the stroke of a car wheel and the torsion bar 6 acts, the spring constant becomes higher. While, when the pump 18 is stopped, the free piston 14 is returned back by the return spring 15 and the torsion bar 6 does not act.
