Title: Manufacture of semiconductor laser element
Inventor: SUGATA SUMIO
IPC: H01S5/22
Filed: 1992-06-08
Abstract: PURPOSE:To obtain a semiconductor laser element wherein its crystal interface defect is small, its threshold value is low and its optical output is high by a method wherein a substrate-plane orientation and a stripe-shaped mesa-slope orientation are made respectively specific and an upper-part clad layer which has been doped with Si is grown at a specific temperature. CONSTITUTION:A substrate-plane orientation is set at a (100) plane and a mesa- slope orientation is set at an (n11) B plane (where n=1, 2 or 3). Upper-part clad layers 4, 5 which have been doped with Si are grown at a temperature of 450 to 560 deg.C. The resistance of the upper-part clad layer 4 on the (100) plane becomes low and the resistance of the upper-part clad layer 5 on the (n11) F; plane becomes high. Then, an SiO2 film 6 in which a window has been worked, an n-electrode 7 and a p-electrode 8 are formed. An electric current which has been injected into the upper-part clad layer 4 from the electrode 7 is not diffused into the upper-part clad layer 5 as a high-resistance layer; it flows wholly to an active layer 3 and contributes to a light-emitting operation. As a result, the threshold value of the title laser element is lowered and the light-emitting efficiency of the title laser element is increased.

IPC: G06F15/00
Filed: 1985-08-10
Abstract: PURPOSE:To use a reserved storage area in common and to reduce the capacity of a storage area by preserving or restoring the system processing state in response to the set state of a saving mode flag. CONSTITUTION:A processing system 10 produces signals after finishing a processing stage in an automatic saving mode together with a saving mode flag set at '0'. In such a case, a preservation control signal is produced and a preservation/restorage processing part 20 superscribes the processing state of the end stage over a preserving area 30 and preserves it. This preservation is replaced for each interactive processing stage. If the preservation and restoration are desired in a saving mode during said interactive processing, a SAVE command signal or a CHANGE-MODE signal is produced for preservation of the state into the area 30 at a desired interactive processing stage. While the saving mode flag is set at '1' and the subsequent preservation/restorage modes are equal to the command saving mode.

Title: Coordinate input device
Inventor: TOKIOKA MASAKI
IPC: G06F3/048
Filed: 1991-07-17
Abstract: PURPOSE:To exactly detect vibration caused by a vibrating pen by eliminating reflected waves from the terminal part of a vibration transmitting board. CONSTITUTION:When a vibration transmitting board 8 is pressed with a vibrating pen 3, the vibration of the pen 3 is detected by vibration sensors 6, and coordinates pressed with the pen are decided. In that case, the reflected waves are generated at the peripheral part of the vibration transmitting body 8 and exerts an adverse influence upon the detection of the vibration at the sensors. Therefore, an outer frame 20 of a main body around the transmitting board 8 is formed with a material having the same acoustic impedance as that of the transmitting board 8 and adhered to the transmitting body 8. Thus, the vibration of the transmitting board 8 is efficiently propagated to the outer frame 20, and the reflected waves can be suppressed.
