Title: Voltage amplifying circuit utilizing semiconductor integrated circuit
Inventor: IDA SHIZUO
IPC: H01L27/04
Filed: 1979-06-28
Abstract: PURPOSE:To keep the voltage gains of a negative feedback amplifying circuit constant without depending upon a temperature by a method wherein sheet resistance with different resistance value is formed by diffusion or the injection of ions. CONSTITUTION:The voltage gains of the input and output signals of a negative feedback amplifier A are displayed at the ratio of resistance R2 connected between output and input terminals to resistance R1 connected to the input terminal. The temperature coefficient of diffusion resistance, whose sheet resistance differs, or resistance by the injection of ions is each different. Consequently, when these resistance is set in R1>R2 the temperature coefficient of the voltage gains is negative, and when the resistance is set in R1<R2 the temperature coefficient is positive. Thus, since the sheet resistance of R1 and R2 is freely selected and the temperature coefficient of the voltage gains of the negative feedback amplifier can be controlled in a positive number, zero or a negative number, the temperature coefficient is easily set when a circuit is connected to the outside, and effect on practical use is great.

Title: Electrophotographic photoreceptor and electrophotographic device
Inventor: WATANABE HISAO
IPC: G03G5/147
Filed: 1995-03-15
Abstract: PURPOSE: To provide an org. photoreceptor drum having excellent characteristics which can be used for a contact electrifying method or contact developing method. CONSTITUTION: This electrophotographic photoreceptor has a photosensitive layer 6 having an org. thin film 5 as the surface formed on a base body 3 and is used for an electrophotographic device of a contact electrifying method. The photosensitive layer 6 is formed to have the film thickness ranging from 9μm to 20μm, while the org. thin film 5 is formed by using a polycarbonate resin having >=40000 mol.wt. as a binder. Since the photosensitive layer 6 is made thin, the surface potential can be increased and a high charge density is obtd. Since the mol.wt. of the binder in the org. thin film 5 is large, the film thickness is hardly reduced, which prevents decrease in the dielectric breakdown voltage because the photosensitive layer 6 partly becomes thin during the use.  It is especially effective to control the surface roughness of the base body 3 to <=0.8μm, because partial deterioration in the dielectric breakdown voltage of the base body 3 due to roughness can be prevented.

Title: Mold clamping device in continuous casting machine
Inventor: TAKASHIBA NOBUMOTO
IPC: B22D11/05
Filed: 1980-06-19
Abstract: PURPOSE: To prevent the clearance between respective molds, the gnawing of copper plates to themselves, and reduce the operator's burden by clamping the long side molds to the short side molds by means of springs of elastic forces larger than the pressure of molten metal and smaller than the thermal expanding forces of the inside surface copper plates of the molds.  
     CONSTITUTION: Long side molds 1, 1' opposedly disposed by holding a pair of short side molds 2 therebetween hold the molds 2 by means of tie rods 30 and springs 36. At this time, the elastic forces of the springs 36 are set larger than the pressure of molten metal acting upon the long side molds and smaller than the thermal expanding forces of the copper plates attached to the molds 2. Hence, when molten metal is poured into the molds, the backward movement of the molds 1 to create clearances with the molds 2 does not occur. Gnawing of the copper plates of the molds 1, 1', 2 to themselves by expanding at the time when the copper plates attached to the molds 2 thermally expand does not occur either. Even more, the small elastic forces of the springs 36 result in reduced frictional resistance between the molds 1 and 2.

Filed: 1993-04-12
Abstract: PURPOSE:To perform speed feedback control quickly and smoothly even in the vicinity of the response limit of it by turning on or turning off a switch circuit, based on the command of a main controller. CONSTITUTION:A motor controller feeds back the quantity of drive of a motor 2 so that the position feedback signal Vh and the speed feedback signal Vvf from an encoder 4 may be equal to the position command Vhs and the speed command Vvs from a main controller 1, respectively. Furthermore, only the speed command Vvs is cut off the feedback control by turning on or turning off a switch circuit 91, based on the command ON/OFF signals of a main controller 1, in operation of feedback control. Hereby, a motor 2 decelerates quickly by the braking force geared to the actual speed, thus the acceleration and deceleration, especially, the deceleration and stop operation can be smoothed quickly in the vicinity of the response limit of the feedback control.
