Title: Double-hetero structure semiconductor laser with device
Inventor: ONO YUICHI
IPC: H01S5/00
Filed: 1987-12-25
Abstract: PURPOSE:To obtain a semiconductor laser device high in output power and reliability easily by a method wherein an optical coupling layer which propagates laser rays is provided to at least one of end face sections in a laser resonator and an active layer is formed so as to be situated at a position where it is optically coupled with the optical coupling layer through the intermediary of a clad layer. CONSTITUTION:A protrudent or a recessed stripe is previously formed on a semiconductor substrate, and a dual double-hetero structure is formed of an optical coupling layer sandwiched in between first clad layers, a laser active layer, and a second clad layer, and the height a of a substrate step is made to be nearly equal to the thickness C between the optical coupling layer and the laser active layer. That is, the laser active layer is made to disappear near an end face through the step so as to be coupled with the optical coupling layer through the intermediary of the clad layer or a transparent section. By these processes, a laser device of this design can be remarkably improved in an optical output breakage limiting value without degrading laser rays in property while a high power is outputted, and as the etching processing of a substrate and a crystal growth can be controlled in thickness, the device can be comparatively easily formed.

Title: Energy supply device
Inventor: IGAWA NORIO
IPC: B66B11/04
Filed: 1990-11-28
Abstract: PURPOSE:To make small incoming power receiving facilities in a building by supplying energy accumulated in an energy accumulating means and energy supplied from outside to an elevator apparatus and other energy loads inside a building. CONSTITUTION:Energy generated by an elevator apparatus is accumulated in an energy accumulating means 36 and the energy accumulated in the accumulating means 36 and the energy supplied from outside are made to be supplied to an elevator apparatus and energy load inside a building. Therefore even when other electric load does not exist inside the building while regenerative braking is actuated, the regenerative brake actuates and the electricity generated is accumulated as an energy. Energy supplied from outside of the building is accumulated during the time zone where energy comsuption is low, such as during the night, and used during the high energy comsuption time zone. Thus power comsumption can be restrained and small incoming power receiving facilities can be made in a building.

Filed: 1990-11-27
Abstract: PURPOSE:To measure torque per rotation angle by acquiring number of counted reference pulses indicating pulse width of a phase difference pulse while timing is shifted for each rotation of a torque transmission shaft. CONSTITUTION:When a torque transmission shaft 1 rotates with torsion, there is a difference in phases between rotation pulses (a) and (b) output from rotation sensors 4,5 so that a phase difference pulse (e) is generated 9. Pulse width of this pulse (e) is converted 11 into the number of reference pulses (f) and the number of the pulses (f) is counted 13. Pulse width of either pulse (a) or (b) is converted 12 into the number of the pulses (f) and counted 14. Further in a post-counter 18, with the counted number of reference rotation pulses (l) by a pre-counter 17 as a preset value, the umber is output as a measurement pulse (g) at the time of counting termination. The pulse (g) delays by one cycle of rotation pulses per rotation of the shaft 1. A CPU 21 acquires the counted numbers of the counters 13,14, and torque at each rotation angle is calculated and then stored in a RAM 22.

An information amount to be displayed by this information code is a value obtained by increasing the number of the kinds of display areas to a power by the number of the arranged display areas. Thus, a large amount of information can be displayed compared with monochrome information codes.
