Title: Semiconductor laser device and its manufacture
Inventor: KUDO HIROAKI
IPC: H01S5/00
Filed: 1994-07-22
Abstract: PURPOSE:To enable stable single transverse mode oscillation and single longitudinal mode oscillation of small oscillation threshold current by forming a diffraction grating on a surface of an optical guide layer formed above an active layer and by providing an epitaxial support layer. CONSTITUTION:Since a diffraction grating 14 is formed on a surface of a surface of an optical guide layer 5 formed on an active layer 3, it is possible to enlarge refraction factor difference in a vertical transverse direction to a resonator direction without damaging combination efficiency between laser beam generated in the active layer 3 and the diffraction grating 14. Therefore, stable single transverse mode oscillation and single longitudinal mode oscillation can be acquired. Since the active layer 3 is not formed on the diffraction grating 14, crystallinity of the active layer 3 does not lower and element characteristic improves as an oscillation threshold current becomes smaller. Furthermore, since an epitaxial layer 16 is provided, change of a configuration wherein a stripe groove 15 is buried is prevented and reproducibility of element characteristic of a semiconductor laser device is improved.

Title: Ignition timing controller for internal combustion engine
Inventor: NAKAJIMA TOYOHEI
IPC: F02P5/153
Filed: 1986-07-22
Abstract: PURPOSE:To make knock occurrence frequency maintainable in spite of a variation in engine speed, by operating plural types of knocking occurrence rates with the operation factor varied according to the engine speed and thereby setting a timing advance correction value. CONSTITUTION:The table value stored in a memory 36c from the engine speed detected via a crank angle sensor 20 is retrieved by a central processing unit 36b at a control unit 36 whereby a reference knock occurring ignition number, a timing advance judging ignition number and a timing advance stand-by ignition number are selected. And, whether there is knocking or not is confirmed from output of a knock sensor 32, and when no knocking occurs there, the knock occurrence factor subtracting the reference knock occurring ignition number by the timing advance judging ignition number is operated. When this knock occurrence factor exceeds the specified value, timing advance correction is stopped, but when it is less than the specified value, the elapse of the timing advance stand-by ignition number is judged and this timing advance correction takes place. With this constitution, even if the engine speed is varied to some extent, knock occurrence frequency is equalizable.

Filed: 1990-06-29
Abstract: PURPOSE:To prolong time for execution in a CPU and to enable the high-speed operation by stopping a refresh operation to a row address which is accessed by the CPU and is the same as actually being refreshed. CONSTITUTION:A storage part 40 is provided to set (or clear) the data of the row address of a DRAM, which is accessed by a program, and to clear (or set) the data in each fixed cycle while being equipped with memory capacity more than the number of all the refresh addresses. When the CPU access a main memory, a row address line 31 is selected as the address of the storage part 40 by a multiplexer 30, and the data of a refresh request line 41 to be a data input in that case is written into the storage part 40 by a write control line 32. In this case, unnecessary refreshing, namely, refreshing not necessary to be executed since being accessed from the CPU is omitted. Thus, the number of times for interrupting the operation of the CPU due to refresh is decreased, and operating speed can be practically improved.
