Filed: 1978-07-04
Abstract: PURPOSE: To prevent superimposition of a control drive current of a power semiconductor by providing an interlock circuit for interlocking the mutual control signals to a signal amplifying amplifier connected to a control electrode circuit.  
     CONSTITUTION: An interlock circuit IL consisting of three transistors TR11∼ TR13 is added to a gate drive circuit of a power semiconductor such as gate turn-off thyristor GTO or the like. On-gate current flows only when both off-pulse transistor TR 5  and bias pulse transistor TR 9  are turned off so that the on-gate current in the GTO does not superimpose with the off-gate and bias-gate currents. Even if there occurs a superimposition due to the delay therebetween by means of the different characteristics of photo couplers PC 1 ∼PC 3 , no superimposition occurs at the final stage to thereby prevent damage of the semiconductor nor erroneous operation of on or off actuation of the semiconductor.

Title: Conductive roller
Inventor: ITO MASAHIKO
IPC: F16C13/00
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent a change in the image concentration by reducing environmental dependency of electric resistance by blending an electron conductive agent, an ion conductive agent and an insulating filler of a specific value to pts.wt. of a specific value of nitrile rubber or hydrogenated nitrile rubber being the base material with a resistance adjusting layer. SOLUTION: An ion conductive agent reduces in resistance at high temperature/high humidity, and increases in the resistance at low temperature/low humidity, and to the contrary, an electron conductive agent has a tendency that resistance increases in a high temperature/high humidity environment and the resistance reduces at low temperature/low humidity. When blending the electron conductive agent and the ion conductive agent with a resistance adjusting layer at an optimized rate, stable electric resistance can be revealed in the resistance adjusting layer, so that the environmental dependency can be remarkably reduced. A change in a resistance value by a difference in an extrusion molding condition of the resistance adjusting layer can also be restrained.  An optimized blending rate of the electron conductive agent and the ion conductive agent is 10 to 150 pts.wt. of the electron conductive agent and 2 pts.wt. or less of the ion conductive agent to 100 pts.wt. of a base material of the resistance adjusting layer.

Title: Pachinko ball supply mechanism
Inventor: MATSUDA TETSUO
IPC: A63F7/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain mechanism where mechanical lock is not executed in pachinko ball supply mechanism for supplying prescribed number of pachinko balls to the ball discharge device of a pachinko machine. SOLUTION: Sensors 23 and 25 are respectively set not only in the entrance but also the exit 11 of a star wheel 1. Unless an entrance sensor 23 detects a pachinko ball 3 during the rotation of the star wheel 1 based on signals detected by the sensors, the rotation of the star wheel is temporarily stopped and a gear-shaped recessed part 5 in the neighborhood of the entrance is controlled so as to be in a stand-by position where lock with the pachinko ball is not executed. The gear-shaped recessed part 5 of the start wheel 1 is also controlled to be in the stand-by position even after the completion of supply after preceding rotation. Thus, locking is prevented and large force is not added to a motor 15 when rotation is executed again.

IPC: H03F3/60
Filed: 1996-04-03
Abstract: PURPOSE: To provide a compact high frequency power amplifier circuit device at low cost by attaining the three-dimensional arrangement of the circuit elements. CONSTITUTION: A layered product 13 includes ceramic substrates 13a to 13c laminated together. A semiconductor chip 1 having an EFT, etc., and a high frequency matching circuit 8 are mounted on the highest 1st substrate 13a. A ground layer 16 is formed on the 2nd substrate 13b, i.e., an intermediate layer to prevent the interference of electric signals against the circuit elements which are arranged on both higher and lower layers. Then a bias circuit 7 and a ground electrode 15 are formed on the upper and lower surfaces of the 3rd substrate 13c respectively. In addition, the leafless electrodes 14 are formed in the areas covering the side faces of substrates 13a to 13c through the upper surface of the substrate 13c.  Thus the total size and the cost can be reduced for a high frequency power amplifier circuit device by means of high thermal conductivity and a proper dielectric constant of the aluminum nitride substrate as well as a three-dimensional structure.

Title: Image forming device
Inventor: SATO SHOGO
IPC: G03G9/097
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To form an excellent image by efficiently recovering toner remaining on a photoreceptor drum after transferring a visible image on the photoreceptor drum. SOLUTION: The toner incorporates charge control resin and the toner remaining on the photoreceptor drum 18 after transferring the visible image is recovered by a cleaner 39 which recovers the toner when a potential difference is given between the drum 18 and the cleaner 39. Since the toner incorporating the charge control resin is hardly electrified to have a reverse polarity by transfer bias applied to an intermediate transfer drum 21 at the time of transferring, it is excellently recovered by the potential difference given between the drum 18 and a cleaner brush 41.

Title: Insulating exhaust pipe
Inventor: ISOBE MICHIO
IPC: H05H7/00
Filed: 1990-03-28
Abstract: PURPOSE:To prevent a high potential part from being discharged and to improve the conductance by providing suppressor electrode, etc., at both end parts of the insulating exhaust pipe which is linked with a beam line pipe at one end and linked with a vacuum pump at the other end. CONSTITUTION:The beam line pipe is evacuated by the vacuum pump in the process wherein an ion beam passes through the beam line pipe to irradiate a target. In this case, the ring-shaped insulating pipes 1 - 5 are stacked in stages across ring-shaped potential plates 6 - 9, so the migration of neutron particles is not impeded and the pipes serve merely as an orifice or wire gauge to improve the conductance. Ions, on the other hand, have potential peak by the suppressor electrodes 11 and 12 at both end parts of the insulating discharge pipes, so the majority of the ions are repelled by resiliency. Ions which are not repelled by the electrode 11 and pass the electrode 11 on the side of the beam line tube are discharged to the plates 6 - 9 as well as discharge to an electrode plate with a half-moon shaped hole to disappear. Further, ions which pass the electrode 12 without being repelled are repelled by the electrode 12 and accelerated to a high potential part side.
