Title: Personal computer
Inventor: NAKAJIMA SHUZO
IPC: G11C16/02
Filed: 1991-01-21
Abstract: PURPOSE:To inhibit writing in an EEPROM when a battery built in a personal computer becomes a low or zero battery state. CONSTITUTION:In a personal computer including the battery, the voltage capacity of the battery is previously detected. When the battery is not in the low battery state, a flag in a prescribed register is set up. A CPU judges the flag of the register and outputs a WRITE ENABLE signal to an inverter 39. An output signal from the inverter 39 is inputted to an OR circuit 41. A WRITE signal outputted from the CPU is inputted to another input terminal of the OR circuit 41. The OR circuit 41 finds out OR logic between both input signals. The output terminal of the OR circuit 41 is connected to the PGM terminal of the EEPROM 2. When an output signal from the OR circuit 41 is a low level, the EEPROM 2 is turned to a write enabled state.

Title: Scroll compressor
Inventor: SUZUKI YASUYUKI
IPC: F04C18/02
Filed: 1990-01-12
Abstract: PURPOSE:To prevent scars on a bearing section and the occurrence of adhesion between a sway scroll and a main spindle by providing a balancer formed on the main spindle and the first and second thrust bearings formed on the first and second frames.

IPC: A61M1/18
Filed: 1990-01-12
Abstract: PURPOSE:To reduce the necessary installation area of a system by generating pressure change in the fluid within a liquid inflow space part and/or liquid outflow space part by the reciprocating movement of a flexible member to allow the fluid to pass through a fluid treatment part. CONSTITUTION:When gas or a liquid is introduced into an operating chamber 8 from a pressure controller 10 through a fluid pressure supply port 7c, a flexible member 6 is reciprocally moved by the fluid pressure and the pressure change of the blood in a fluid inflow space part 4 is generated by the reciprocating movement of the flexible member 6. Therefore, by the pressure change and the action of two check valves 9, 13, the blood introduced from a blood introducing port 7a smoothly flows through a hollow fiber bundle 3 from the fluid inflow space part 4 to a fluid outflow space part 5 as shown by an arrow and gas exchange is performed between said blood and the oxygen-containing gas introduced from a gas introducing port 14 on the way. By this method, the installation area of the system can be reduced.

Abstract: PURPOSE:To facilitate the change of a cutting edge in a tape cutting means, to shorten a change time and to surely fix the cutting edge in a prescribed position with a good accuracy by moving the cutting edge to a position dislocated from a tape mounting base and changing the cutting edge. CONSTITUTION:When a time to change the cutting edge comes, a spacer 48 is raised, it is moved until a stopper 38 is abutted to a supporting base 36, namely, up to a position where a cutting edge 28 is dislocated from tape mounting bases 24 and 26 further beyond a reciprocating range A for cutting a tape on the tape mounting bases 24 and 26, and the cutting edge 28 is changed in such a condition. When the cutting edge 28 is changed in such a way, since the cutting edge 28 is located in the position dislocated from the tape mounting bases 24 and 26, a changing work cannot be prevented by the tape mounting bases 24 and 26, and the changing work can be smoothly executed. Thus, the changing work time can be shortened, and simultaneously, the cutting edge can be surely fixed in the prescribed position with a good accuracy.
