Title: Manufacture of semiconductor laser device
Inventor: UNO TOMOAKI
IPC: H01S5/11
Filed: 1986-12-26
Abstract: PURPOSE:To simplify a manufacturing process, and to improve the yield of an element while enabling excellent single longitudinal mode oscillation having the large coupling coefficient of beams and a diffraction grating by forming a semiconductor laser device with the diffraction grating through two-times of crystal growth processes by using a vapor crystal growth method. CONSTITUTION:A clad layer 2, an active layer 3 and a waveguide layer 4 are crystallized onto a substrate 1 in succession. A diffraction grating pattern is shaped onto the waveguide layer 4 through a two-beam interference exposure method, and the surface of the waveguide layer 4 is etched selectively by the diffraction grating pattern, thus forming a diffraction grating 5. Striped patterns are shaped to the surface of the waveguide layer 4, on which the diffraction grating 5 is formed, in the direction vertical to grooves for the diffraction grating. The waveguide layer 4 and the active layer 3 are etched selectively, employing the striped patterns as masks, and a laser resonator 6 is shaped. A current confinement layer 7, a current confinement layer 8, a clad layer and a contact layer 9 are crystal-grown in succession by using an MO-VPE method. Zn is thermally diffused to the surface of the contact layer 9 until Zn reaches to the current confinement layer 7, employing an silicon nitride film with a striped opening as a mask, thus forming a Zn diffusion region 10.

Title: Method and device for editing digital signal
Inventor: TSUJI SHIRO
IPC: G11B27/02
Filed: 1988-12-09
Abstract: PURPOSE:To efficiently edit digital signals by incorporating a fixed length editing memory in a VTR. CONSTITUTION:A tape reproduced digital audio signal and an input digital audio signal from terminals 23 and 24 are written in a tape memory 61 and a source memory 62 until an entry key (EK) of an operation switch 19 is depressed, and signals for a certain time before the present input signal are always stored there. When the EK is depressed, a stop command is inputted to a W address counter (AC) 29 by a system controller (SC) 18 after the holding state, and an address just preceding the stop address is transferred to a RAC 31 to output a start signal. A memory address switching multiplexer 25 supplies the output of the counter 31 to the memory 61 to read out contents by a request after the stop command is outputted from the SC 18. Consequently, when the EK is depressed in the editing mode, audio information for several tens seconds before and after this depression is stored in the memory 61 and can be reproduced and monitored any number of times by a rehearsal request. Thus, signals are efficiently edited.

Patent JP-H02160335-A (JP)
Title: Method and device for exposure
Inventor: MASUDA MIYOJI
IPC: H01J9/20
Filed: 1988-12-13
Abstract: PURPOSE:To enhance the accuracy of the form and positioning of the opening of a carbon layer so as to prevent generation of failure in pressure resistance and/or abnormal discharge, by guiding light from a light source by means of an optical fiber, when providing the carbon layer with the opening, and selectively exposing photoresists to form a photoresist layer. CONSTITUTION:An exposure system comprises an optical fiber 4, a mask 2 attached to the end of the fiber 4 and provided with an opening in a predetermined form, and a light interrupting plate 9 arranged in opposite relation to the opening. When e.g. an ultraviolet lamp is lighted, ultraviolet light is guided by the optical fiber 4 and radiated from the end of the mask 2, and in this case the sectional form of the optical path of the light reflects the form of the opening provided through the mask 2 with extremely high precision; when a photoresist is developped, a photoresist layer in a predetermined pattern such as in the form of dots or stripes is therefore formed in an effective picture and another photoresist layer corresponding to the form of the opening of the mask 2 with precision is formed outside the effective picture. The accuracy of positioning and form of the window of a carbon layer finally formed is thus enhanced to prevent generation of failure in pressure resistance between cathode rays and/or abnormal discahrge.

Abstract: PROBLEM TO BE SOLVED: To attain the use of an existing model checking tool with no correction required by producing a state graph generator having a corrected multiprocessing system to be checked by adding many rules to a generator to much reduce the state graph to be generated. SOLUTION: The initial state of a system is selected based on a certain initial condition (100) and stored in a list. Then all enable subsequent states are calculated from the selected initial state and a subset of enable transistors coincident with conditions C0 and C1 is selected about an ample set (110). If the subset is not detected (120), an entire set of enable transitions is selected (130). Then a state where every transition contained in the ample set moves in the system is calculated (140) and stored in the list (150). Then it's judged whether a state that is not studied yet is displayed (160). If the said state is displayed, a transition that is not studied yet is selected from the list (170).
