Title: Electrophotographic receptor
Inventor: YOSHIHARA YOSHIYUKI
IPC: G03G5/05
Filed: 1982-02-02
Abstract: PURPOSE:To always obtain a stable potential with less memory effect caused by repeated charging cycles, by using a specified acrylic resin as a binder in a photoreceptor having a photoconductive layer contg. CdS.nCdCO3 bound. CONSTITUTION:CdS.nCdCO3 is susceptible to the content of carboxylic groups in the molecule of an acrulic resin, deteriorated in dispersion when the content is low, and when high, improved in dispersibility, but the resin, itself, is made liable to vary due to application of high humidity in its insulation performance, so the resin is controlled to give 10-40 acid value. The resin having >=10,000mol wt. and low mol.wt. precipitates rapidly in a dispersion step. Since the glass transition point Tg is within 15-70 deg.C, variations of the envoronmental temp. give a little effect on the characteristics of the photoconductive layer.

Abstract: PROBLEM TO BE SOLVED: To prevent the fatigue failure of the circumference of the flange of a cylinder liner in the cast iron cylinder liner, by forming the sliding part of the cylinder liner from a perlite texture, and forming a non-sliding part from a bentonite texture. SOLUTION: A cylinder liner comprises a cylinder 2 and a flange 3, and a abrasion relief groove 4 is arranged under the flange 3. The flange 3 is tightened between a cylinder head and a cylinder block. Therefore, rupture occurs easily by action of tightening force and action of repeating stress per process of an engine. Hereupon, the flange 3, the abrasion relief groove 4 and their circumferential part 8-1 are heat treated so as to be a bentonite texture. When this heat treatment is executed, while a cylinder liner inner circumferential surface 5 is cooled by cooling water from a cooling pipe 10, current is applied to a high frequency coil 9, and a part 8 is heated by induction heating, thus, this part 8 is made to be an austenite texture. Next, air is sprayed to a heated part so as to be air-cooled, thus the heated part is made to be a bentonite texture.

IPC: H02M7/497
Filed: 1992-01-31
Abstract: PURPOSE:To make an inexpensive low-speed switching element which is less in steady-state loss usable by switching two of three up-down arm circuits by using the basic frequency of the output of an inverter and controlling the remaining up-down arm circuit by using a frequency higher than the basic frequency of the inverter output. CONSTITUTION:Transistors 1, 3, 8, and 10 are turned on and transistors 2, 4, 7, and 9 are turned off when the output voltage of an inverter is in a positive half-period. On the contrary, the transistors 1, 3, 8, and 10 are turned off and transistors 2, 4, 7, and 9 are turned on when the output voltage of the inverter is in a negative half-period. When transistors 5, 6, 11, and 12 are modulated in pulse width in such a state, an AC output is obtained. Therefore, even when pulse width modulation is performed at a high frequency, no expensive high- speed switching element having a large steady-state conducting loss is required for the semiconductor switching elements of this inverter.

Filed: 1989-01-25
Abstract: PURPOSE:To shorten the access time of a disk drive by reading plural sector data scattered on the tracks out of the disk drive to the different memory addresses for each sector and then writing these sector data into the disk drive from the different memory addresses. CONSTITUTION:A table retrieval control circuit 4 retrieves a sector control table 5 based on the sector number latched by a sector latch circuit 3. Then a data transfer address is set to a DMA controller 6 as long as a data transfer enable bit is set. The data transfer direction is set to the controller 6 and a disk control circuit 8 so that both the controller 6 and the circuit 8 are set in a transfer enable state respectively. Thus the data on other tracks are trans ferred in the case a sector track counter 4.1 is equal to 0 for a track selected by a head selecting signal 13. As a result, the access time to a disk drive is shortened.

IPC: F42D1/02
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To obtain sufficient explosion effect and to reduce blasting energy being transferred to the surrounding by punching a required number of explosion holes from the peripheral surface of an object to be broken at the outer periphery of a core hole and loading explosive into the explosion hole for exploding. SOLUTION: A core hole 2 is excavated at an exploded part 1, and a sufficient free surface 1 for improving the efficiency of blasting is composed by the inner-periphery surface of the core hole 2 and that of a remaining outer- periphery part 12. Also, at the outer-periphery part 12, a required number of explosion holes 3 are punched from the peripheral surface, and required explosive is loaded into the excavated explosion holes 3. Explosives such as dynamite being used for the publicly known blasting method are used.  Also, since the exploded part 1 has a sufficient free surface 11, sufficient blasting can be made with much less amount also for the amount of explosives to be used as compared with a method for blasting an entire section by blasting, thus reducing blasting energy to be transferred to a peripheral part and fully clearing an allowable vibration value to surrounding houses and the like.
