Title: Punch for extruding and production thereof
Inventor: KOBAYASHI TATSUNOBU
IPC: B22F3/20
Filed: 1993-09-06
Abstract: PURPOSE:To form micro ruggedness on the surface of a punch made of cemented carbide without producing residual stress in the punch. CONSTITUTION:Intergranular Co in WC grain is oxidized by oxidizing the surface of a cemented carbide punch 2. Further, oxidizing treatment is executed from the surface of the punch 2 down to the range exceeding a size of WC grain. After Co is oxidized and removed from the surface of the punch 2, WC grain is exposed, fine ruggedness is produced on the surface corresponding to an outside diameter of the grain. Accordingly at extruding, detaching the punch 2 from a work 4 is made easy. Further, by removing intergranular Co in WC grain, the intergranular residual stress in WC grain combined each other is reduced.

Title: Control method in air conditioner for automobile
Inventor: MORI AKIRA
IPC: B60H1/00
Filed: 1982-12-20
Abstract: PURPOSE:To reduce power consumption of a battery and improve control accuracy by a method wherein air conditioning is made with all ducts being open until compartment temperature reaches a preset value after start of air conditioning, thereafter the duct(s) corresponding to the vacant seat(s) is closed to make constant discharged heat of ducts corresponding to the occupied seats, and opening and closing of the ducts are then repeated in accordance with the difference between the compartment temperature and a preset value. CONSTITUTION:A microcomputer receives inputs including compartment temperature 50, etc. and performs cooling/heating for a certain time in accordance with the given program. This is made with all ducts being opened. When the compartment temperature reaches a preset value, discharged air heat values at respective discharge ports are computed based on discharge temperatures 60-64 and speeds of not shown motors and then stored. Vacant one(s) out of seats 30-34 is detected by passenger sensors 41-44. If one or more vacant seats are present, the corresponding ones of the ducts 41-44 are closed and associated blower motors are decelerated to make opening degree control of a mixing door in accordance with the number of passengers. Thereafter, when the difference between the compartment temperature and a preset temperature exceeds a predetermined value, the blower motor speed is increased and all ducts are opened. With this arrangement, it becomes possible to reduce power consumption of a battery and enable precise control of temperatures.
