Patent JP-H05308781-A (JP)
Title: Inverter controller
Inventor: OMORI YOICHI
IPC: H02M7/48
Filed: 1992-04-28
Abstract: PURPOSE:To resume the operation of a motor immediately after the voltage of a smoothing capacitor becomes higher than the voltage necessary for operating a PWM inverter and then a power failure finishes by installing a command limiter which limits a torque command and a magnetic flux command or a current command which corresponds to those commands with a power failure detecting signal. CONSTITUTION:A command limiter 9 receives a torque command T1 and a magnetic flux command phi1 from a torque and magnetic flux commander 6 and it usually outputs these commands as they are to a PWM inverter 4 as a torque command T2 and a magnetic flux command phi2. When the command limiter 9 receives a power failure signal from a power failure detector 7, it outputs to the PWM inverter 4 a zero torque command T2 and a magnetic flux command phi2 which is smaller than the magnetic flux command phi1 output from the torque and magnetic flux commander 7. By this method, the PWM inverter 4 continues to work only with the power stored in a smoothing capacitor 3 without stopping. When the power failure finishes in a short time, no operations are required for resuming the operation of a motor such as synchronization and protection from overcurrent due to a residual magnetic flux and then the operation of the motor can be resumed immediately after the power failure finishes.

Title: Power supply system for power amplifier
Inventor: SAKAMOTO TAKAO
IPC: H03F1/30
Filed: 1981-08-28
Abstract: PURPOSE:To improve the overall gain of a power amplifier, by providing a switching circuit which switches each voltage and applies the voltage to an amplifying transistor (TR) of the next stage, between both power supply lines to which the voltages are supplied from a stabilized power supply and a battery power supply. CONSTITUTION:When a battery power supply is in normal operation, since a voltage on a power supply line 5 is higher than that of a power supply line 4, diodes 11, 12 in a switching circuit 10 are respectively turned off and on. Thus, a voltage of the line 4 is applied to a TR1-1 of the 1st stage, while a voltage of the line 5 is supplied to TRs 1-2 and 1-3. Thus, a higher voltage is applied to the TR1-2 from the line 5 than that of the line 4 and the grain can be increased. In case of a failure where the line 5 is lower in voltage than the line 4 due to fluctuation of the battery, since the diodes 11, 12 of the circuit 10 are respectively turned on and off, then a stabilized voltage is applied to the TR1-2 from the line 4, allowing to suppress the reduction in the gain.

Title: Manufacture of gate turn-off thyristor
Inventor: KUSANO MITSUO
IPC: H01L29/74
Filed: 1984-06-30
Abstract: PURPOSE:To improve the reverse withstand voltage at junctions by a method wherein the surface of a P type semiconductor layer is provided with a P type expitaxial layer of low impurity concentration, and an N type impurity is deposited on its surface and then diffused by intrusion into the boundary region of said epitaxial layer. CONSTITUTION:A P type semiconductor layer P2 (gate layer) is formed by diffusing a P type impurity from the surface of an N type semiconductor layer N1. Next, the P type epitaxial layer P<-> of low P type impurity concentration is formed on the surface on this semiconductor layer P2. Then, a deposition layer N<+> is formed by depositing an N type impurity on the surface of this epitaxial layer P<->; thereafter, this impurity is diffused by intrusion to the boundary region between the semiconductor layer P2 and the epitaxial layer P<->. Thereby, an N type semiconductor layer N2 serving as the cathode layer is formed by junction on one surface side of the semiconductor layer P2. Since this manner enables the layer P2 to have the peak of impurity concentration at the part other than the end in the thickness dcirection, the reverse withstand voltage VGR can be increased with the reduction in resistance of the semiconductor layer P2.

Abstract: PURPOSE:To execute a test of a data processor in circumstances where the preceding controlling function is exerted to the maximum capacity by executing a test in which states of various buffer memories and registers in hardware and operations in each stage of preceding arithmetic operations are combined to the instruction on the conditional branching unsuccessful side also. CONSTITUTION:In the course of a preceding controlling function test having plural streams, a branching instruction, especially a conditional branching instruction is produced as the succeeding instruction of the instruction for setting a condition code from random number data 36 and information in an instruction parameter table 50. Moreover, a testing instruction for working plural streams can also be produced, since a testing instruction is produced to a branching unsuccessful side also when branching is established by the condition code. Then a data processor to be tested is caused to execute these testing instructions so as to cancel the results of the preceding execution of the stream on the branching unsuccessful side. Therefore, a test in which the preceding controlling function, states of various buffer memories and registers in the hardware, and operations in each stage are combined can be executed in circumstances where the preceding controlling function is exerted to the maximum capacity.

IPC: G01R31/28
Filed: 1987-05-29
Abstract: PURPOSE:To check the frequency of a CR oscillator, which is self-oscillating in an IC, readily, by inputting a sampling frequency into a clock input terminal in a testing state. CONSTITUTION:Terminals P1 and P2 are used to output the judge result of the frequency of a built-in CR oscillator 9. When the oscillator 9 is oscillating at a desired frequency, a sampling signal, whose frequency is higher than the oscillation frequency of the oscillator 9, is applied to a PG terminal from an external LSI tester. When the oscillation frequency of the oscillator 9 is lower than the desired frequency at this time, the width of a pulse during the high level period of the oscillation frequency becomes long. The number of the pulses at the high level of the sampling frequency is increased. Latch outputs at a high potential are taken out of the terminals P1 and P2. Meanwhile, when the oscillation frequency of the oscillator 9 is higher than the desired frequency, the pulse width during the high level period of the oscillation frequency becomes short. Then, the number of the pulses of the sampling frequency at the high level is decreased. The latch outputs at a low potential are taken out of the terminals P1 and P2.

Title: Surface displacement measuring instrument
Inventor: OKI YASUSHI
IPC: G11B7/26
Filed: 1986-06-12
Abstract: PURPOSE:To accurately measure the displacement quantity of the reflecting surface of, for example, an optical disk covered with a transparent layer without being affected by a transparent layer by setting the angle of incidence upon the surface of the transparent layer to the Brewster angle of the transparent layer. CONSTITUTION:Laser light LA 1 emitted by a light source 3 passes through a polarizing plate 5 to become a P polarized parallel light beam, which is incident on the optical disk 1 at an angle theta of incidence. When the angle theta is set to the Brewster angle of the transparent layer 2, the light LA 1 is not reflected by the layer 2, but enters the layer 2 and is reflected by the reflecting surface 1f. Its reflected light LA 2 is incident on a condenser lens 6 with focal distance (f). (A photodetecting element 7 composed of, for example, a two-dimensional image sensor arranged in the direction as shown by an arrow (x) is provided at the focus position of the lens 6 so that the photodetection surface is perpendicular to the optical axis. If the surface 1f slants by a fine angle delta, the light LA 2 slants by the angle 2delta, the spot position of incidence on the element 7 shifts. The element 7 sends out its (x)-directional and (y)-directional outputs which vary according to the displacement quantity of the element 7. Those measured values, distance (f), and angle theta are used to find the angle delta.
