Title: Motor structure of working car
Inventor: MIZUNO RYOJI
IPC: H02P29/00
Filed: 1990-02-19
Abstract: PURPOSE:To effectively and economically carry out the driving of an electric fan by detecting the voltage of back electromotive force generated concomitant with the rotation of an electric fan for cleaning caused by radiator cooling wind, and by driving the electric fan for a predetermined period of time only when the voltage is not more than a preset value. CONSTITUTION:An electric fan 11 is rotated when cooling wind is smoothly taken in from an intake, and is rotated reversely by the cooling wind. At the time, the voltage of back electromotive force generated in the motor M concomitant with the reverse rotation, is detected by a voltage detection part 10, and the detected voltage and a preset reference voltage are compared with each other by a voltage comparator 15. When the detected voltage is lower than the reference voltage, a control system 18 is driven through a one-shot multivibrator 16. Namely, a timer T is operated for a short predetermined period of time, and a motor drive circuit 17 is turned 'ON' by a relay Ry, while an electromagnetic clutch 14 is turned 'OFF'. The electric fan 11 is driven, while a cooling fan 12 is stopped, thereby.

Title: Synthesis of diamond
Inventor: IIZUKA EIICHI
IPC: B01J3/06
Filed: 1983-03-14
Abstract: PURPOSE:To produce diamond crystals having uniform grain size, by disposing minute particles of a nucleating substance sporadically in a system for the synthesis of diamond under high temperature and pressure. CONSTITUTION:Diamond is synthesized under high temperature and pressure using a non-diamond carbon and a solvent metal such as Fe, Co, Ni, Cr, Ta, etc. In the above process, minute particles of a substance capable of easily forming diamond crystal nucleus, e.g. a metal or its alloy having lower melting point than the solvent metal, are arranged in the synthesis system keeping the particles from mutual contact in plane or in three-dimensional manner interposing nearly equal distance between the particles. The control of the synthetic condition of diamond can be facilitated by the process, and the generation of new nucleus in the unwanted region can be suppressed even if the condition of temperature and pressure is deviated to an extent from the otherwise rigorously restricted condition. Accordingly, a high-quality diamond can be synthesized in a practical rate of growth.
