IPC: G03G5/02
Filed: 1988-12-08
Abstract: PURPOSE:To improve the characteristic to hold accumulated information charges by successively laminating a photoconductive or conductive fine particles on an insulating layer provided on an electrode and laminating a charge transfer layer thereon. CONSTITUTION:The photoconductive or conductive fine particles 12 are laminated in the form of a single layer or plural layers on the insulating layer 11 provided on the electrode 13 and thereafter the charge transfer layer 10 is laminated successively thereon.

Title: Inter-machine ball lending machine and its control method
Inventor: SAKAMOTO MASASHI
IPC: G07F11/00
Filed: 1991-11-26
Abstract: PURPOSE:To prevent a power supply circuit from being overloaded by momentary flow of a large current due to the simultaneous start of operation that lent balls are discharged in accordance with remaining money at the time of power-on after a power failure in the case that many inter-machine ball lending machines are provided. CONSTITUTION:Remaining money is discriminated in a step ST2 after power-on; and if remaining money exists, the wait time due to random number values generated in a step ST3 is set in a step ST4, and the normal ball lending operation is started in a step ST10 after the elapse of the wait time in a step ST5. Consequently, the start time of the operation requiring a high power consumption is different among inter-machine ball lending machines though remaining money exists, and the momentary occurrence of a large current is prevented.

Title: Transmission disconnection detecting circuit for digital radio communication system
Inventor: KUME TOMIYUKI
IPC: H04L27/00
Filed: 1987-12-10
Abstract: PURPOSE:To detect disconnection of a corresponding transmitter accurately by detecting a transmission center frequency and an intermediate frequency corresponding to the frequency deviated to both sides by a prescribed frequency from the center frequency and interrupting the transmission output when the amplitude difference of adjacent detection output signal strings is a prescribed value or below. CONSTITUTION:A frequency control circuit 72a generates a signal varying the frequency sequentially and periodically being the center frequency f'0 corresponding to the transmission frequency f2 of the transmitter and frequencies f'-, f'+ deviated to both sides of the center frequency by DELTAf in the order of lower frequency. A judging circuit 74a synchronizes a detection output S71 by a timing signal S72B from a frequency control circuit 72a and uses an AD converter 741 to convert it into a digital value. A comparator circuit 743 compares the preceding digital conversion value latched by a latch circuit 742 with the present digital conversion value from the AD converter 741 synchronously with the 2nd internal timing signal S74B. Thus, even with the presence of adjacent channel interference, the transmission disconnection of the corresponding transmitter is detected accurately.

IPC: G03G15/043
Filed: 1986-12-27
Abstract: PURPOSE:To make the border part of entered characters sharp and to prevent the generation of rippling by arranging a lens array between an exposing light emitting part and the surface of a photosensitive drum. CONSTITUTION:The lens array 400 is arranged between the LED element 41b and the photosensitive drum 61. The array 400 is coupled with a plate 414 by an L-shaped part 418 through a pin 417 plated into a body frame 800 and constituted so as to be rotated around the pin 417 as shown in an arrow (a). Since the array 400 is arranged between the element 41 and the drum 61 and LED light is prevented from being diffused, the border part of entered characters is made sharp at the time of entering characters or the like. In case of editing copying such as erasing and trimming, the array 400 is removed, so that rippling due to the positional unevenness of removed charge can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To secure sufficient strength and to improve capacity efficiency when a positive electrode is loaded with a high current by mixing manganese dioxide particles with a graphite dispersing solution containing an organic polymer and forming it into an electrode molded body by means of press molding. SOLUTION: After dry mixing electrochemically refined manganese dioxide(EMD) with graphite-dispersed solution, the graphite-dispersed solution is sprayed in a mixer in operation, or slowly introduced there. After further mixing KOH (potassium hydroxide) aqueous solution is fed to it and is homogenized depending on a case. In this case, the addition of the KOH solution component and the graphite-dispersed solution may be performed by mixing them with a suitable quantitative ratio and by feeding them together into a dried mixture. Thereby, the graphite-dispersed solution is distributed well depending of each mixing system. Then, after the electrode mixture for a cathode is rolled into a solid band-like article, it is crushed into a desired particle size in a granulating process, formed into a fluid (granular) cathode material and press-molded according to a cell type.
