Title: Semiconductor laser and its manufacture
Inventor: MURAKAMI TAKASHI
IPC: H01S5/00
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser which is controllable in a lateral mode, possessed of a narrow radiation beam, high in output power, low in threshold value, and long in service life by a method in which a current blocking layer is provided onto a substrate along a waveguide layer. SOLUTION: When a P-AlGaAs clad layer 2, a P-AlGaAs active layer 3, an N-AlGaAs clad layer 4, and an N-GaAs contact layer 5 are successively grown on the surface of a P-GaAs substrate 1 through a vacuum organic metal vapor growth method, the layers 2 to 5 are not grown on an SiO2 film 9 but on a part where the P-GaAs substrate 1 is exposed. Therefore, GaAl is more supplied to a stripe section than to a laser chip edge face, so that a semiconductor laser where the layers are thicker in the stripe section than in the vicinity of the edge face of a laser chip can be obtained. A semiconductor laser of this constitution is possessed of an edge face which is lessened in thickness, so that it is capable of projecting a narrow beam.

Title: Data processor
Inventor: SUZUKI HIROSHI
IPC: G06F11/34
Filed: 1988-04-26
Abstract: PURPOSE:To leave the address of a microinstruction next to the microinstruction in which an error is generated by generating a clock stopping signal by a clock synchronized with the clock set on a microinstruction data register. CONSTITUTION:An error detecting signal 8 is generated by inputting error signals equivalent to the number of constituents 5 in a configuration unit to an error control circuit 7. The error detecting signal is latched at a latch 9 by the clock T0 synchronized with the clock T3 set on the microinstruction data register 4. When the error detecting signal 8 is latched at the latch 9, an AND gate 11 blocks the passage of the clock T2, and the content of a microinstruction address register 2 ceases to be updated.

Abstract: PURPOSE:To reduce a maintenance job frequency at the part of a reading means by providing a comparison means which compares the output value of the information read by the reading means with the reference value and a control means which drives an informing means with the output of the comparison means. CONSTITUTION:The output VCMP of a comparator 7 is applied to an input terminal IN of a counter 8. A count output terminal OUT of the counter 8 is connected to a discriminating means 9 via a terminal IN2 of a microcomputer 4. A microcomputer 3 reads the output state of the counter 8 and decides the degree of contamination of a magnetic head 1 via the means 9. When the need for cleaning maintenance is judged for the head 1, a drive circuit 10 is driven by a control circuit 12 via a terminal OUT2. Then an LED11 serving as a display means is turned on to inform a maintenance worker of the contamination of the head 1. As a result, the maintenance jobs carried out at each fixed time can be decreased regardless of the degree of contamination of a magnetic reading means.
