Title: Tracing device
Inventor: SEGAWA YUKIHIRO
IPC: G06F11/28
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To inexpensively provide a tracing device with which an infinite loop part can be found in a short time by comparing an address set by a comparative address setting circuit with an address outputted by a CPU through an address comparator, counting the number of times of matching through a counter and displaying the result. SOLUTION: A tracing device 6 is connected to the address bus of CPU 1 so that the address outputted by the CPU 1 at the time of reading/writing a memory 2 and a strobe can be inputted to the tracing device 6 as well. When the strobe is inputted, an address comparator 20 compares the address inputted to the tracing device 6 with the address set by a comparative address setting circuit 23 and when these addresses match, a matching signal is outputted to a counter control circuit 21. Each time the matching signal is inputted from the address comparator 20, the counter control circuit 21 outputs a count-up signal to a counter 22. A CPU 27 reads out the value of counter 22 and displays that value on a display device 29.

Title: Manufacture of semiconductor laser device
Inventor: ENDOU KENJI
IPC: H01S5/00
Filed: 1984-02-02
Abstract: PURPOSE:To provide a semiconductor laser device which has a small threshold current and can produce a large output in a basic transverse mode, by including a diffusing process in which an active layer portion near the lower portion of the groove is converted into a P type one to form a current injecting section and the surface layer of the groove is converted into the P type layer having a depth which does not reach the reflective faces at both the longitudinal ends of the groove. CONSTITUTION:At a first diffusion, a high-concentration diffusing process which results in the carrier concentration above 10<19>cm<-3> is done to form a high-concentration P type area 6. At a second diffusion, with a pushing diffusion process, high-concentration impurities being already diffused are more deeply diffused, forming a P type area 7 with a low carrier concentration. In this way, a portion of the active layer 3 is converted into a P type one having a carrier concentration of 1-5X10<18>cm<-3> to form a current injecting section 12 which has a forbidden band width difference and a refractive index difference in comparison with the unconverted N type area. Both the longitudinal ends of the current injecting section 12 are formed so as to space away from the pair of the reflective faces 11, 11' respectively. In this diffusion, if a carrier concentration of the first N type clad layer 2 is set at a value above 5X10<15>cm<-3>, the P-N junction can be formed in correspondence with the active layer.

Title: Protecting device for rotary electric machine
Inventor: KOIKE TSUTOMU
IPC: H02H7/093
Filed: 1981-02-10
Abstract: PURPOSE:To prevent the burnout of the electronic parts of a drive circuit and the coils of a rotary electric machine by providing pulse generating means for generating pulses of intervals becoming wider as the rotating speed is decelerated and controlling the drive circuit with the pulses. CONSTITUTION:A pulse generator 3 which generates pulses of intervals becoming wider as the rotating speed of a rotary electric machine 1 is decelerated is provided. One shot pulse is fed from a malfunctioned rotation detector 5 produced upon operation of a start switch 6 through a drive circuit 4 to supply a current to the machine 1. When the rotating speed of the machine 1 is normal at this time, it is continuously rotated by the pulse from the generator 3. Since the interval of the pulses from the generator 3 becomes wider when the rotating speed is abnormally decelerated, it is detected by the detector 5, thereby stopping the supply of a current of the drive circuit 4. In this manner, the burnout of the elecric parts of the drive circuit and the coil of the rotaty electric machine can be prevented.
