Title: Door lock device
Inventor: TORII NOZOMI
IPC: E05B81/66
Filed: 1995-06-08
Abstract: PURPOSE: To reduce operational failure by water and dust from outside through grease and a latch mechanism by arranging a cam lever by performing insert molding on a flat spring, between a latch cam and a courtesy switch. CONSTITUTION: A cam lever 82 which is formed by performing insert molding on a flat spring 83 whose on end 831 is locked on a housing 3 and other end 832 is opposed to a switch part 8a and which is energized in the clockwise direction, is arranged between a cartesian switch 8 and a latch cam 81 of a latch 41. When a door is latched by rotating the latch 41, a cam lever 82 rotates, and the other end 832 of the flat spring 83 comes into contact with the switch part 8a, and confirms a latch condition. When it is unlatched by rotating the latch 41, the other end 832 of the flat spring 83 separates from the switch part 8a, and detects an unlatched condition. Since the courtesy switch 8 and the latch 41 separate from each other, operational failure of the courtesy switch by water and dust from outside through grease and the latch 41 is reduced. The number of part items can also be reduced.

Title: Semiconductor laser
Inventor: HANAMITSU KIYOSHI
IPC: H01S5/20
Filed: 1983-08-04
Abstract: PURPOSE:To obtain excellent effects in a change into low threshold currents, astigmatism, etc. by each forming a gain confinement type waveguide selectively in the axial direction of a resonator and an index confinement type waveguide to a residual section communicated with said waveguide. CONSTITUTION:In a GaAs/GaAlAs group semiconductor laser, a gain confinement type waveguide section 8A is formed so that a P type conversion region 7 does not penetrate an N type Ga1-xAlxAs active layer 3. The region 7 penetrates the layer 3 in an index confinement type waveguide section 8B. Consequently, P-N junctions are formed in arrow 7A and 7B sections. According to such structure, an advantage at a time when the structure of a resonator is formed to a complate gain confinement type or a complete index confinement type can be kept at a level in a certain extent. As a result, practically sufficient performance can be displayed in the points of astigmatism, threshold currents, noise strain characteristics by modal noises, etc.

IPC: G06F13/38
Filed: 1985-06-28
Abstract: PURPOSE:To attain the bidirection a transfer of data between devices by means of a data line and a clock line. CONSTITUTION:When a key is operated on a keyboard device, a control unit 30 produces the key code data corresponding to the operated key and stores temporarily this data in an internal buffer memory. Then the transmission of data is possible when a terminal 9 of the unit 30 is set at 'H' level, and a clock signal is sent to a clock line 42 from a terminal 10. At the same time, said key code data is sent serially to a data line 41 from a terminal 8 synchronously with the clock signal. While the line 41 is forcibly set at 'L' level after all bits of the key code data are sent. This fact is detected by a terminal 7 via a gate TG1. Thus it is possible to know that all data are transmitted correctly to the side of an interface 20.
