Title: Printed wiring board structure
Inventor: YOSHINAGA MASAHIRO
IPC: H05K7/20
Filed: 1988-01-14
Abstract: PURPOSE:To improve a radiation effect and miniaturize its structure as well, by providing through holes at prescribed positions and arranging a semiconductor integrated circuit in each through hole of a printed wiring board having a metal plate which is closely jointed onto at its rear, thereby causing its package part to come into contact with the metal plate through a thermal conduction grease. CONSTITUTION:A printed wiring board 1 has a through hole 1a which corresponds to outside dimensions of a semiconductor integrated circuit 3 at a prescribed position, and a metal plate 6 is closely jointed onto the rear of its board by using adhesives 5. The semiconductor integrated circuit 3 is packaged in such a way that it is dropped into the through hole 1a of the above board 1. Then, its package part comes into contact with the metal plate 6 through the grease 7. Further, a plurality of electronic parts 2 are mounted on the surface of the board 1. As the heat of the semiconductor integrated circuit 3 is transmitted and radiated to the metal plate 6 through the thermal conduction grease 7, a highly efficient radiation effect is obtained, besides, as the thickness is suppressed to the extent of a thinner one, its structure is miniaturized.

Title: Logical simulator
Inventor: HASEBE TETSUYA
IPC: G06F11/25
Filed: 1990-01-12
Abstract: PURPOSE:To increase a simulating speed by handling the memories contained in a logic circuit as plural multi-input/uni-output cells and reading/writing the data out of/into the memories as necessary within a RAM. CONSTITUTION:The data stored in the memories (RAM 2 and ROM) forming a logic circuit to be simulated are previously stored in the exclusive RAM (RAM 2 and ROM data memory 28) contained in a logic simulator. A simulation chip 1 handles the memory 28 as plural multi-input/uni-output cells and at the same time reads and writes data out of and into the exclusive RAM 2 as necessary. Thus the simulation is carried out without answering a versatile computer during the simulation even with a logic circuit that contains the memories like the RAM 2 and the ROM, etc. As a result, the simulating speed is increased.

Title: Speed controller for motor
Inventor: OOMAE TSUTOMU
IPC: H02P7/292
Filed: 1982-01-18
Abstract: PURPOSE:To eliminate the damage of a machine which is driven by a motor by outputting a motor stop command when one-phase signal of an encoder is displaced to special level so that the absolute value of a speed feedback amount becomes lower than the prescribed value. CONSTITUTION:The absolute value of a speed feedback amount NF is counted by an absolute value circuit 13A, and is compared by the prescribed value by a comparator 13B, which generates an output of one level when the prescribed level becomes larger than the absolute value of the NF. On the other hand, the output DP of a malfunction detector 11 is inputted as one input to an AND circuit 13C, and becomes one level when one phase becomes defective. As a result, a stop signal generator 13 generates a stop signal ST when the speed of a motor 2 becomes lower than the prescribed level. When the stop signal ST is generated, it opens a power switch, thereby stopping impression of the voltage  to the motor 2.

Abstract: PURPOSE: To extend a used band and make it possible to perform a good-linearity delay modulation by correcting previously a control signal in a correction circuit which has a transfer function shown in a specific expression.  
     CONSTITUTION: Correction circuit 7 is inserted between control signal 6 and voltage-frequency converter 5, and the control signal is compensated to improve the characteristic. Correction circuit 7 branches the input signal applied to input 8 into two, and one is applied to inversion input terminal 11 of wide-band amplifier 10 through resistance 9, and the other is applied to non-inversion input terminal 14 wide-band amplifier 10 through the voltage divider circuit of capacity 13. The output of this amplifier is not only connected to output terminal 15 but also fed back to inversion input terminal 11 through resistance 16. Transfer function G(f) of this circuit is as shown in formula I; and if frequency fO of a phase delay of π/2 is made equal to frequency fO of the sound signal, the phase delay dependent upon a charge transfer element and the phase delay of correction circuit 7 become π/2 together and agree with each other. As a result, a used band is extended, and linearity of delay modulation can be improved.

Title: Position sensor
Inventor: MATSUDA MICHIYA
IPC: G01D5/12
Filed: 1982-01-20
Abstract: PURPOSE:To form the highly sensitive position sensor, wherein the displacement and  angle change of a body are transduced into an electric signal by utilizing a vibrating element. CONSTITUTION:An elastic wave exciting coil 2 and an elastic wave detecting coil 3 are  wound around an amorphous magnetostriction thin plate 1 with an appropriate interval being provided in the advancing direction of the elastic wave as shown by an arrow.  Both ends of the magnetostriction thin plate 1 are supported by bent pieces 11a and 11b of a long supporting body 4, which are bent in an approximately C shape. A  permanent magnet 5 is arranged in the amorphous magnetostriction thin plate 1, so  that a bias magnetic field is applied in the width direction. When a pulse current as  shown in the Figure is flowed in the coil 2, the elastic wave is excited by the magnetostriction effect in the magnetic plate at the winding part of the coil 2. Then, the elastic  wave is propagated in the magnetostriction thin plate 1 in the direction of the arrow,  and detected as the electric signal Q again by the reverse magnetostriction effect of  the elastic wave detecting coil 3. Since the bias is increased and decreased by the displacement and the angle change of the permanent magnet 5, the displacement and the  angle change of the permanent magnet 5 can be detected as the electric signal.
