Title: Semiconductor luminescent device
Inventor: TAKAGI NOBUYUKI
IPC: H01S5/20
Filed: 1983-08-25
Abstract: PURPOSE:To enable to obtain a semiconductor laser element, whose threshold-value current is low and luminous efficiency is high, at a higher yield by a method wherein the optical waveguide region is made to coincide with the current region in a self- matching way. CONSTITUTION:An N type GaAs layer 9 with a flat surface is laminated on a P type GaAs layer 8, a quarangular cylinder-shaped diffusion source 10, wherein the cross section vertical to the long axis is trapezoidal and the lower bottom of the trapezoid is facing the side of the layer 8, is provided on the layer 9, and a substrate is constituted. A P type first clad layer 2, an active layer 1 and an N type second clad layer 3 are successively laminated on the substrate. In this constitution, when impurities are diffused in the range indicated by dotted lines from the diffusion source 10, only the part of the layer 9, where is included in the range, is turned into a P type and the other parts of the layer 9 remain to be an N type. Accordingly, in case bias voltage is impressed in the forward direction between the layer 8 and an electrode layer 13, current concentrates in the vicinity of the protruded tip face of the diffusion source 10 and only the part of the layer 1, where is opposed to the protruded tip face, becomes a luminous region. That is, the optical waveguide region and the current region are made to mutually coincide in a self-matching way.

Title: Flame detector
Inventor: KATOU SHIYOUZOU
IPC: F23N5/08
Filed: 1983-08-25
Abstract: PURPOSE:To enable the checking for flame depending on infrared rays emitted from a combustion gas of the flame by providing an infrared ray detection element for detecting infrared rays emitted from the combustion gas at the position allowing the detection of the combustion gas and a comparator which provides the flame detection output when the pulsating output exceeds a specified value. CONSTITUTION:As a flame 5 ignites in a burner 2, a high temperature combustion gas is generated at the top of the flame 5. This combustion gas pulsates depending on the flow and the temperature thereof and the infrared rays emitted pulsate. When the infrared rays are detected with an infrared ray detection element 1, the detection intensity involves a pulsation. Only alternating components of the pulsation are amplified with an amplifier 8 after the removal of low frequency noise components with a high pass filter and further, rectified with a rectifying element 13 and a capacitor 14. The resultant rectification output is compared with a specified voltage determined by the division of resistances 16 and 17 with a comparator 15, which outputs a flame detection signal when the rectification output exceeds the specified value and a relay 18 is turned ON to send the flame detection signal.

Title: Memory error detection control system
Inventor: SAITO HIROYUKI
IPC: G06F12/16
Filed: 1989-06-20
Abstract: PURPOSE:To surely detect the memory error due to noise or the like by comparing data read out from a sample memory part and that from a data latch part with each other. CONSTITUTION:Since data is written in a sample memory part 2 by the same operation as a large-capacity data memory part 1, erroneous data is written there if noise is superposed. However, a data latch part 3 is scarecely affected by noise to latch data because the set-up time is short. Consequently, data read out from the sample memory part 2 and latched data in the data latch part 3 are compared with each other by a comparing part 4 after the data write operation to discriminate whether data is correctly written in the data memory part 1 or not. Thus, the memory error due to noise is surely detected.

Abstract: PURPOSE:To maintain the image-formation in an overall focusing state even if an uneven and curved shape of the work surface is changed in the middle by using a bendable thin film mask of a laser beam transmissible material whose pattern is formed of a laser beam untransmissible material layer to prevent a crack of the pattern. CONSTITUTION:First, a reflection thin film 13 of a pattern part is removed from an intermediate product state which is formed by applying or adhering the reflection thin film 13 to a transparent thin film 12 simple substance to form the mask 16. In case there is the unevenness on the surface of a work 15, the mask 16 is bent following the unevenness. For this purpose, both edges in opposition of the mask 16 are supported by a supporting body 17 capable of bending the shape freely and the shape is controlled by a controller 20. Accordingly, even if the surface shape of the work 15 is changed to a different one, the surface shape of the mask 16 can be controlled correspondingly and the pattern can be always imaged in the overall focusing state on the surface with the uneven or curved shape of the work 15.

Abstract: PURPOSE:To enhance traveling smoothness, durable strength, manufacturing operability, and appearance of a support structure by a method in which when the opening and closing motions of any of doors are energized, all the doors are integrally and concurrently operated by varying the connecting states from vertical row to parallel or vice versa so that desired closing, opening, and putting-in or out operations can be transmitted. CONSTITUTION:A runner 16 is attached with the same interval as the setting width of rails C in a housing part B on the flat face of a supporter I, and a partition part D is attached to the opposite face of the place with the runner 16. The supporters are set in parallel and their coupling edges 5, coupling grooves 6, and other side downward coupling grooves 8 and downward coupling edges 9 are connected into a whirl form. In the parallel state, the runners 16 are coupled with the rails C to enable the connected parts to move laterally. The manufacturing operability can thus be raised due to the formation of the supporter unit from single elements. Also, no trouble with collision during traveling period does not occur due to no projecting constituents.

Title: Transmission power control system for satellite communication
Inventor: ODA HIROBUMI
IPC: H04B7/005
Filed: 1988-06-22
Abstract: PURPOSE:To compensate precipitation attenuation by a fixed quantity and to attain a satellite communication system to be operated by plural ground stations can be operated by the plural stations by detecting satellite receiving power data at every incoming line frequency from the plural stations and transmitting the data to each ground station. CONSTITUTION:In order to transmit signals for communication from a ground station 2 to ground stations 3 and (n) satisfying a prescribed channel quality, the transmission power is controlled by calculating precipitation attenuation quantities of incoming channel 4-6. Namely, a satellite reception power detection circuit 1a sends back the detecting data of the satellite reception power when it rains at the incoming channel 4 to the ground station 2 after superposing the data upon telemeter signals and performing frequency conversion. The ground station 2 calculates the precipitation attenuation quantity by comparing the sent satellite reception power when it rains at the channel 4 with already known data of fine weather and transmits the signals for communication to the stations 3 and (n) by increasing the effective radiation power of the station 2 by the attenuation quantity. Similar transmission power control is performed based on detecting data transmitted from satellite reception power detection circuits 1b and 1n when it rains at the incoming channels 5 and 6 of the ground stations 3 and (n).
