Title: Semiconductor laser element and its manufacture
Inventor: MURATA KAZUHISA
IPC: H01S5/00
Filed: 1978-05-23
Abstract: PURPOSE: To secure the current stenosis at the region of the NP structure to cause concentrically the laser oscillation there as well as to increase the life time for the laser element by forming the region of the NPNP 4-layer structure onto the compound semiconductor substrate with holding the mere NP-structure region in- between.  
     CONSTITUTION: P - -type region 13 is formed on N - -type GaAs substrate 1 by diffusing Zn with Al 2 O 3  used as the mask. Then the mask is removed to grow in lamination N - -type Ga 1- XlAXAs layer 2, P -  or N - -type GaAs layer 3, P - -type Ga 1- XAlXAs layer 4 and P + -type GaAs layer 5 each on the entire surface including region 13. After this, P-type electrode 7 or N-type electrode 8 are coated on layer 5 and on both surfaces of substrate 1. Thus, the NPNP 4-layer structure of N - P - N - P - P - P +  is caused at the area where region 13 is formed; while a mere NP structure of  N - N - P - P - P +  is grown at the area without region 13 formed. In such constitution, the current is stenosed at the area where no region 13 is formed to secure concentration of the laser oscillation there.

Title: Protecting apparatus for uninterruptive power supply unit
Inventor: INAGAKI FUMIO
IPC: H02H3/20
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To suppress red heat and smoke generation of a varistor inserted into the input side of an unintierruptive power supply unit, by providing connectively a voltage-sensing circuit between its neutral and grounding terminals, and by breaking via a solid-state relay its input-side current, when sensing the generation of a voltage not smaller than a fixed value. SOLUTION: Between a grounding terminal G and a neutral terminal N of the input side of an uninterruptive power supply unit 1, a voltage-measuring circuit (sensor) 2 is provided connected to measure always its input voltage. A control circuit 4 always compares a measured voltage V with a preset voltage (reference voltage) VO. When the voltage V exceeds the voltage VO, the control circuit 4 sends a signal to a solid-state relay(SSR) 3 to break a hog-side circuit connected to the uninterruptive power supply unit 1. At the same time, the control circuit 4 sends a signal to an alarm unit 5 to issue to workers an alarm by a sound/light. As a result, the uninterruptive power supply unit 1 itself can be prevented from being destroyed by an abnormality voltage, and the connecting of a varistor, etc., with it can be dispensed with.

IPC: G06F11/10
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To improve an error detection rate by changing the correspondence of data byte, error correction code symbol and memory at an error correcting circuit capable of detecting an error by reading only the partial memory from the erroneous address by dividing a memory control circuit into two or four pieces even when any fault occurs at one piece of memory control circuit (especially address signal). SOLUTION: The data of 16 bytes are divided into four groups of bits 0-3 of bytes 00-07, bits 4-7 of bytes 00-07, bits 0-3 of bytes 08-1.5 and bits 4-7 of bytes 08-15, and the respective groups are made correspondent to four small check matrixes of S4EC-D4ED cyclic error correction codes. At the same time, four small check matrixes are made correspondent to the memory grouped into four by memory control divided into four pieces. Thus, when the data are the repetition of the same byte data, the error detection rate is remarkably lowered.

Title: Abnormality detecting method for compressor
IPC: G01M13/00
Filed: 1992-03-18
Abstract: PURPOSE:To detect the abnormality of a compressor accurately at the early period at the initial stage by detecting the current changing speed in operation, comparing the speed with a normal current changing speed, and judging the abnormality at the time when the difference exceeds a specified value. CONSTITUTION:A test driving instruction is inputted into a computer 9. A compressor 1 (electric motor 2) is started. The armature current value (the measured value of an ammeter 10) of the electric motor 2 is read at a specified sampling pattern. The current changing speed at a steady operating period is operated and stored into the memory of a reference value register. A current detecting circuit 11 is connected to the armature current loop of the motor 2. The current value (analog signal) after the starting period of the motor 2 is outputted into the computer 9. The detected current value of the circuit is converted into the digital value at the specified period in the computer 9 during the normal operation, and the changing speed of the armature current is computed. The deviation between the speed and the current changing speed stored in the reference-value register is obtained. When the deviation exceeds the reference value, an abnormality alarm is issued, and the current conduction to the motor 2 is stopped by the Trip command (a).
