Patent JP-H0340796-A (JP)
Title: Driving circuit for stepping motor
Inventor: SOEJIMA RYOTA
IPC: H02P8/00
Filed: 1989-07-07
Abstract: PURPOSE:To obtain a motor driving circuit having predetermined performance with a simple structure by applying a pulse voltage to a coil corresponding to a plurality of phases of pulse signals synchronized with a pulse signal of first pulse rate. CONSTITUTION:A CPU generates a pulse signal SCLK of first pulse rate. A phase signal generator(PHG) 4 generates a plurality of phases of pulse signals synchronized with the pulse signal of the CPU. On the other hand, a pulse voltage generator 3 generates a pulse voltage of second pulse rate larger than the first pulse rate. A switching driver(SDR) 5 applies the pulse voltage of the generator 3 to corresponding motor coils according to the pulse signals of the phases of the generator(PHG) 4. Desirably, the CPU varies the first pulse rate. Thus, lower power, low heat generation, etc., are performed with a simple structure without chopper driving.

IPC: H01L21/30
Filed: 1982-10-05
Abstract: PURPOSE:To obtain a uniform photo resist pattern by reciprocating a developer nozzle rectangularly to a wafer diameter above the rotating wafer and thus spraying a developer over the diameter. CONSTITUTION:The wafer 31 is chucked 21 and rotated at 50rpm, and the developer is sprayed out of the nozzle 23 over the diameter.

IPC: B65H67/04
Filed: 1981-10-30
Abstract: PURPOSE:To prevent wound yarn from collapse in transportation thereof by dropping a bobbin into a chute in taking up yarn after yarn take-up is completed, cutting off the yarn by a hot wire and transferring continuously wound bobbins. CONSTITUTION:A bobbin 18 is sandwiched and rotated between a drive disk 3 and a frictional disk 11 by a yarn winder, and a yarn 25 from a yarn feeding section 52 is wound around the outer periphery of the bobbin 18 by a yarn guide.

The bobbin rolls in the direction of yarn winding on the chute when the tension is absent so that wound yarn is prevented from collapse while the bobbin can be transferred. Further only by adapting a yarn carrier installing unit to the direction of winding yarn to the bobbin and the inclined direction of the chute, the bobbin can be stopped temporarily also on the chute in the cutting-off of the yarn so that the transporting operation of the bobbin can be carried out continuously and the wound yarn can be prevented from collapse.

IPC: B60K23/00
Filed: 1985-08-09
Abstract: PURPOSE:To secure good drivability at a low temperature range as well as to shorten a span of worming-up time, by setting a shift-up point or a criterion for shift indication to the high-speed side at a time when suction air temperature is lower than the criterion suction air temperature set to be lower than the criterion engine temperature. CONSTITUTION:A car speed V and a temperature TW of the engine mounted on a car both are detected, and when this detected engine temperature TW is lower than the criterion engine temperature, a criterion car speed should be set to be higher as compared with the case being high. And, on the basis of the compared result between this detected car speed and the said criterion car speed, shift indication is carried out. In addition, an engine suction air car speed, shift indication is carried out. In addition, an engine suction air temperature TA is detected, and when this detected suction air temperature TA is lower than the criterion suction air temperature set to be lower than the said criterion engine temperature, the criterion car speed is set to be yet higher. Therefore, even at a low temperature range, good drivability is securable, and worming-up time is also reducible. And, suction air temperature comes to a parameter which shows a state of atomization in a relatively accurate manner so that drivability is set better securable.
