Patent JP-S62264680-A (JP)
Title: Light-emitting diode
Inventor: HIRAHARA KEIJIRO
IPC: H01L33/28
Filed: 1986-05-13
Abstract: PURPOSE:To obtain emission of infrared or visible light with high efficiency, by providing a hetero junction of Ga1-xAlx-As/Ga1-xAlxAs on a p-type ZnSxSe1-x (x<1) while utilizing the ZnSSe as a light-emitting window. CONSTITUTION:Among P-N junctions of III-V family compound semiconductors, a double hetero junction of GaA As is selected since it has a less reabsorption effect by peripheral crystals, while ZnSSe is selected for a material of a sub strate since crystals thereof have the minimum mismatch in lattice with mixed crystals of GaAs-AlAs. For example, n Ga0.7Al0.3As 12, n-Ga0.9Al0.1As 13, p-Ga0.7 Al0.3As 14 and p-ZnSSe 15 are deposited on an n-GaAs substrate 11 sequentially in that order so that light can be emitted from the p-ZnSSe. In this manner, a infrared-lightemitting diode emitting light with a wavelength of 840nm and having an external quantum efficiency of 45% can be obtained. When Ga0.5Al0.5 As is selected for the first layer, Ga0.7Al0.3As for the second layer and Ga0.5Al0.5 As for the third layer, a highly efficient red-light-emitting diode emitting light with a wavelength of 660nm and having a quantum efficiency of 7% can be obtained.

Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain a next requested music in a short time by measuring the time to be required for performance for every requested music, and changing stand-by time corresponding to result of measurement. SOLUTION: A center device 1 instruct a video disc player B, which is not playing or which is waiting, to prepare the performance of a requested music showed in the information on the number of the next requested music. When the video disc player B concludes the preparation of performance, the video disc player B transmits the conclusion of preparation of performance to the center device 1. When a video disc player A concludes the performance of a first requested music, the video disc player A transmits the conclusion of performance to the center device 1. The center device 1 immediately informs the conclusion of performance of the first requested music to a terminal device 2. Consequently, the terminal device 2 can obtain the time required for the performance of the first requested music, and the stand-by time of a following music is set.  The center device 1 outputs the music start information for the following music to the terminal device 2, and the video disc player B generates the performance starting command.

Title: Aligner
Inventor: MURAYAMA MASAYUKI
IPC: G03F7/20
Filed: 1995-04-07
Abstract: PURPOSE: To make only a block, including a construction member requiring repair or adjustment, exposed to the atmosphere by partitioning a sealed space at any time with partitioning means to form sealed compartment blocks. CONSTITUTION: A space in sealing means 11 can be partitioned at any time by a plurality of partitioning means to form a plurality of sealed compartment blocks. Therefore, for example, in case an optical member 3c, constructing an illuminating optical system, requiring repair or adjustment, partitioning means 18b and partitioning means 18a are blocked at their openings and only a compartment block 19b including an optical member 3c can be exposed to the atmosphere. After the repair or the adjustment of the optical member 3c has been carried out, a vacuum pump 6 is operated to evacuate the compartment block 19b, and gas resubstitution can be effected by supplying an inert gas from gas supplying means 10.  Because the exposure to the atmosphere and the gas resubstitution may be carried out only for the compartment block including the constructing member requiring the repair or the adjustment, the waste of the resubstituting gas can be minimized and the gas resubstitution can be effected quickly.

Filed: 1984-05-30
Abstract: PURPOSE:To prevent the inadvertent start of an engine in a simple ways by installing a safety relay which deenergizes a power-source relay when a photocoupler is operated during the time when a timer is operated by the turning-ON of a manual switch. CONSTITUTION:When a clutch is set at a position other than neutral, a microswitch S6 is in ON-state. Therefore, when a manual-automatic mode selecting manual switch S2 is automatically turned ON, an electric current flows into the luminous element of a photocoupler C1 through the manual switch S2 and the microswitch S6, and a relay X12 is turned ON, and a a-contact 121 is closed to operate a buzzer BZ, and a safety relay XF is turned ON. Since the a-contact XF1 of the relay XF is closed and self-retained, and a b-contact XF2 is opened, the relay XE is cut-off from a battery B. Since the a-contact XE1 is not closed, an engine is not started even if a welding rod is brought into contact with a welded article, and safety is secured.
