Title: Blade cleaning device
Inventor: SAITOU KINJI
IPC: G03G21/00
Filed: 1981-12-14
Abstract: PURPOSE:To elevate a cleaning effect, and also to prevent damage of the surface of a carrying body, by a simple constitution, by providing a spring member and a pressure member on 2 holding members for holding a blade, in an electrostatic recording device. CONSTITUTION:The first holding member 3 which has stuck a blade 1 to the tip is coupled with the second holding member 4 having a fixed shaft 7, with a shaft 5. By a pressure member 8, and a spring 6 installed to a floating supporting point 5, the blade 1 is made to press-contact with the surface of a latent image carrying body 2, and an angle theta1 is ser to <=90 degrees. By a toner 9 which has been stuck to the surface of the carrying body, the tip of the blade receives resistance and floats up, an angle theta2 made by the holding members 3, 4 becomes small, and force of the spring 6 operates. Therefore, the more a stuck toner exists, the larger the press-contact force of the blade becomes, and the remaining toner on the carrying body is removed enough. The press-contact force in case when the remaining toner is a little is comparatively weak, therefore, when the blade is not used, it is unnecessary to separate it from the surface of the carrying body, and also the surface of the carrying body is not dama ged.

IPC: B62D6/02
Filed: 1983-10-27
Abstract: PURPOSE:To secure the proper steering feeling by separately installing a pressure control valve for front-wheel operating means for assisting the steering of a steering wheel and the deflection of a front wheel and a pressure control valve for a rear-wheel steering means for deflecting a rear wheel and increasing the steering repulsive force for the steering wheel according to the increase of car speed. CONSTITUTION:Since the amount of discharge of a pump 24 is reduced and the repulsive fore which a pinion gear 4 receives is reduced in high-speed turning, each opening port of variable orifices (b) and (c) reduces, and the oil pressure supplied into a power cylinder 6 is reduced. Therefore, an assisting force is reduced, and a steering force is reduced, and the amount of discharge from a port 29a increases, and the amount of feed into a large-diameter hole increases. Therefore, a valve spool is slightly driven, and the amount of feed into the cylinder 6 by a pump 24 is reduced, and a steering repulsive force generated on a steering wheel 66 is increased, and proper steering feeling can be secured. Thus, the generated oil pressure in the pump 24 is controlled by a valve 58 and supplied into the cylinder 6, and the generated oil pressure in a pump 27 is controlled by a valve 60 and supplied into cylinders alpha-delta, and the front and rear wheel systems can be controlled separately.

Abstract: PROBLEM TO BE SOLVED: To reduce cost and to miniaturize a DC-DC converter by providing a comparator for supplying a voltage which is proportional to a voltage to an output terminal to an inverted input and a drive circuit for turning on a switching element at a specific time interval by receiving the output voltage. SOLUTION: When an input voltage VIN is applied to an input terminal IIN and a reference voltage VREF is applied to the non-inverted input of a comparator IC2 , the output of the comparator IC2 reaches a high level since the inverted input of the comparator IC2 is at zero potential. Then, a drive circuit IC1 turns on a P-channel MOS transistor Q. Then, an output voltage VOUT, namely the voltage of the inverted input of the comparator IC2 increases and the output voltage reaches a low level and then the transistor Q is turned off by the drive circuit IC1 . The output voltage VOUT is maintained at a preset value according to the relationship between the sum of the on and off periods of the P-channel transistor Q, namely a switching time, and an on/off ratio.

Title: Thermal printer
Inventor: NOUYAMA TAKAYUKI
IPC: B41J2/32
Filed: 1989-08-04
Abstract: PURPOSE:To effect high-guality printing at all times by providing a preliminary heating heater on a thermal head. CONSTITUTION:When a printing data 17 is sent into a CPU 15, the correction of the printing data is effected in every one line printed by the printing data 17 by a temperature correcting circuit 16 in accordance with the data of a head temperature, sent from a temperature detecting circuit 14. The corrected printing is effected in accordance with the condition of the head temperature by the electrification of a thermal head 1, which is effected by sending the corrected printing data into a thermal head driving circuit 11. When the head temperature, detected by a head temperature detecting thermistor 2, is lower than the range of temperature correction, the CPU 15 does not electrify the thermal head 1 and does not receive the printing data while the electrification of a preliminary heating heater 3 is started by a preliminary heating control circuit 12 and the heating of the thermal head 1 is effected until the head temperature arrives at a temperature whereat the temperature correction can be effected by the temperature correcting circuit 16. According to this method, the printing, stabilized at all times, may be effected.
