Title: Coin supervisory system
Inventor: OYAMADA TAKASHI
IPC: H04M17/00
Filed: 1978-06-30
Abstract: PURPOSE:To detect the presence or absence of the coins at both the dial turning time and the dial releasing time via the dial turn detection circuit and the dial transmission detection circuit. CONSTITUTION:When the dial is turned, short contact DS is switched on to give flashing to luminous element EL1. Thus photo detector PT2 is switched off, and voltage Vpt2 turns to the H level. This change is differentiated by capacitor C6 and resistance R13, and the light emission is given to EL1 via transistor Tr6. If the coin exists at the side of element EL1, FF2 is not set. Accordingly, SCR is off to enable the dial transmission. Impulse contact Di is switched off while the dial is being turned, and capacitor C5 is switched on via Zener diode ZD2 and inventer IN1.  Thus, EL1 is made to emit the light to detect the presence of the coins. If no coin  exists there, SCR is turned on to block the dial transmission.

Title: Production of carrier for developing electrostatic charge image
Inventor: OMURA TAKESHI
IPC: G03G9/113
Filed: 1989-03-29
Abstract: PURPOSE:To improve the coating state and coating efficiency of a coated carrier by positioning the end of a release port for fine resin particles to be supplied to the max. flow rate region of the flow of the carrier core material in a chamber of a dry process coating device. CONSTITUTION:The end 53 of the release port for the fine resin particles to be supplied is positioned to the max. flow rate region of the flow of the carrier core material in the chamber 1 of the dry process coating device. The generation of lumped grains by the secondary flocculation of the fine resin particles is obviated in this way and the stable triboelectrostatic chargeability is obtd. Since the fine resin particles are supplied to the max. flow rate region of the carrier core material, the destruction of the particles to primary particles by the impact force received from the core material progresses efficiently and the film of the clathrate layer which is free from fluctuation in the thickness is formed by a plastic deformation, by which the impact force necessary for fixing is uniformly imparted. The carrier having a smooth surface, high deposition strength and high durability is produced in a short period of time.

Title: Direct-coupled amplifier
Inventor: YAMAGUCHI HIROYASU
IPC: H03F1/30
Filed: 1978-06-30
Abstract: PURPOSE:To secure the steady operation state quickly at the power making time through a simple and economical constitution as well as to prevent effectively the occurrence of the pop noise by adding the high-speed charging element which operates only at the power making time. CONSTITUTION:Constant current source IS starts its operation at the power making time, and thus intermediate-step transistor TrQ3 and then output-step transistor TrQ4 become active. Thus, the potential of output terminal OUT tries to rise up until TrQ4 reaches the saturation state. As the base potential of TrQ3 rises up during this process, high-speed charging transistor TrQ5 also becomes active to supply the current. Thus capacitor C of the negative feedback circuit is charged quickly through resistance RE and R2. In this way, the entire amplifier features the steady active state before capacitor C is charged from TrQ4 through resistance R3 and R2.
