Title: Dc motor
Inventor: AOKI KANEMASA
IPC: H02K23/66
Filed: 1988-04-06
Abstract: PURPOSE:To protect a brush surface and the like from a spark, by juxtaposing the DC resistors and capacitors of a spark control circuit in parallel with an armature coil and by setting the capacity of said capacitor at a specific value. CONSTITUTION:A DC motor is equipped with a three-phase   connection armature and a spark control circuit for controlling a commutation spark is provided between the commutator risers of said motor. A series circuit of a DC resistor R and capacitor C is used as said spark control circuit and connected in parallel with an armature coil to constitute said control circuit. Then, said resistor R is made equal to the DC resistance value of said coil and the capacitance of said capacitor is selected at the value of 0.1-1.0muF. Thus, even if the overvoltage of a driving power supply, not a surge voltage, is added to said value, an apparatus can be protected without making thermorunaway like a varistor.

Title: Stereoscopic television control system
Inventor: HOSODA SATOSHI
IPC: H04N13/04
Filed: 1986-04-11
Abstract: PURPOSE:To view a stereoscopic image and a normal image with a shutter device mounted by providing a shutter control means which has mode transition from opening control over both light shutter to opening/closing control a specific time when a start is set and also has transition from the opening/closing control to the opening control when an end is set. CONSTITUTION: When the display of a stereoscopic image is set by a setting means provided to a main body device 11 or shutter device 9, an RC signal for starting is transmitted by radio from one device to the other for a certain period. Both devices begin to display the stereoscopic image and perform the opening/closing control over left and right light shutters 12l and 12r from the rear edge of the constant period a specific period for synchronization later and thus the display of the stereoscopic image and the opening/closing control of both light shutters are started synchronously. When the stop of the display of the stereoscopic image is set, an RC signal for ending is transmitted by radio from one device to the other for a certain period and then while the main device stops displaying the stereoscopic image, the shutter device opens both light shutters. Consequently, the stereoscopic image and normal image are viewed normally with the shutter device mounted.

Abstract: PURPOSE: To elevate the torque-speed characteristic and the efficiency by switching a half-wave type cycloconverter and a primary voltage control in combination.  
     CONSTITUTION: In a low speed area where the output signal level of a speed setter 11 is lower than the reference value of the output of a switching level setter 14, a comparator 15 fails to produce a signal. A switch 6 is closed with a signal L outputted from a switching signal geneator 16 to turn the connection of a main circuit 3 of an induction motor 2 to a three-phase AC half-wave type cycloconverter. A voltage of a tacho generator 8 is computed 10 with the output of the speed setter 11 and the output is fed to a gate control circuit 13L by way of a speed control amplifier 12 to control a thyristor device 3 with the output thereof. When the output of the setter 11 is larger than that of the setter 14, a comparator 15 provides an output to close a switch 7 with a signal H of a generator 16 while the switch 6 is opened. With a gate control circuit 13H, the connection of the main circit is turned to a thyristor diode mixed antiparallel type three-phase primary voltage control power converter.

Title: Ac/dc converter
Inventor: MOGI SHIGERU
IPC: H02M7/04
Filed: 1990-04-02
Abstract: PURPOSE:To reduce the size of an AC/DC converter by arranging an arbitrary units of thyristor modules in a container having ground potential and filling the grounded container with semi-solid insulating material.

Filed: 1989-04-04
Abstract: PURPOSE:To perform an optimum printing in a simple and easy manner at all times even if the type of a cutform is changed by previously reading the type of a cutform to be printed through an identification code and adjusting a printing head and others. CONSTITUTION:On a cutform F to be printed, an identification code 2 corresponding to the type of the cutform F is provided. While the cutform F provided with the identification code 2 is fed toward a printing head 6a of a printer 6, the identification code 2 is read through a sensor 4.

Title: Emitter-coupled logic circuit
Inventor: HIROMOTO MASASHI
IPC: H03K19/086
Filed: 1987-04-07
Abstract: PURPOSE:To realize power consumption with a low level and to accelerate a processing, by connecting the collectors of switching transistors to the emitters of emitter follower transistors, respectively, and connecting the base of the emitter follower transistor on one side to the collector of the emitter follower transistor on the other side, and the base of the transistor on the other side to the collector of the transistor on one side. CONSTITUTION:Assuming that a signal of level L is inputted to an input terminal 1N, the transistor Q1 is turned OFF, and the transistor Q2 is turned ON. By turning OFF the Q1, a Q3 is also turned OFF, and when the Q3 is turned OFF, the collector potential of the Q3 goes to almost the ground potential. Thereby, from an output terminal Out2 and an output terminal, the inverse of Out2, voltages lower than an output terminal Out1 and an output terminal, the inverse of Out1 by a voltage between the bases and the emitters of a Q4 and the Q3 are outputted, and the output terminals, the inverse of Out2 and the Out2 become low impedance outputs. In such a way, a Miller effect can be suppressed, and a capacitance between the base and the collector of the Q1 and the Q2 by appearances when being observed from the input terminal 1N is reduced. In such a way, a fast processing can be realized.

Abstract: PURPOSE:To enable the inspection of any damage and the judgement as to the acceptability of an element to be made in high reliability and efficiency by a method wherein two each of visual inspecting interconnections are extended in the proper interval around the periphery of element division-formed from a semiconductor wafer into a chip to be connected to each other by vlsual inspecting resistors. CONSTITUTION:When a damage X caused to the periphery of an element 2 does not reach an outer visual inspecting interconnection 6 not to disconnect the same 6, if the visual inspecting interconnections 6, 7 are impressed with specified voltage, both interconnections 6, 7 are supplied with current through visual inspecting resistors 8 so that the current may be calculated since multiple resistors 8 are connected in parallel with one another between the interconnections 6 and 7. On the other hand, when the damage X caused to the periphery of element reaches the outer visual inspecting interconnection 6 to disconnect the same 6, some of the visual inspecting resistors 8 are opened to decrease the current. Resultantly, the degree of damage to the element 2 can be inspected making reference to the difference in the features.
