Title: Semiconductor light-emitting device
Inventor: NAKAJIMA KAZUO
IPC: H01S5/00
Filed: 1986-06-11
Abstract: PURPOSE:To improve the characteristic of a semiconductor light-emitting device by a method wherein a buffer layer made up of strained superlattices having different lattice constants is made to grow on a substrate and a semiconductor light-emitting element is formed thereon. CONSTITUTION:When a layer of strained superlattices 2 is formed of InGaAsP layer having different lattice constants on an InP substrate 1, in other words, when a then InGaAsP film of a first composition having a larger lattice constant than InP and a thin InGaAsP film of a second composition having a smaller lattice constant than InP are laminated alternately, atoms in each layer are put in such a configuration as to alleviate a deformation which is caused by the mismatch of the lattice constants in the configurations of atoms in the layers Besides, the occurrence of a defect due to the the mismatch can be prevented when a semiconductor layer having different lattice constant from the one of the substrate 1 is made to grow on the straine of superlattice. Thereby the characteristic of a semiconductor light-emitting device is improved.

Title: Gas control device
Inventor: SUGANO YOICHI
IPC: F16K27/00
Filed: 1992-05-27
Abstract: PURPOSE:To provide a gas control device, which does not require any indirect connecting means such as piping, pipe fitting, etc., between unitary functioning parts, can be accomplished at a low cost, occupies less space, and presents less amount of gas release. CONSTITUTION:A gas control device is installed in a flow line for high purity gas and is characterized by directly coupled three or more unitary functioning parts 2, 3, 4, 6, 7 consolidatedly. This direct coupling of three parts eliminates provision of any indirect connecting means for connecting them such as a pipe fitting, etc., which saves cost accordingly and lessens the space occupied. Because of elimination of necessity for joint connection and welding connection, the total amount of external leakage is lesser, and also the gas release amount is less due to small total surface area of the piping inner surfaces to lead to prevention of the gas purity from dropping.

Title: Chinese character input device
Inventor: INOUE CHIYUUYA
IPC: G06F17/22
Filed: 1979-10-23
Abstract: PURPOSE: To improve operation when a document where the same Chinese character is used continuously is inputted, by inputting the Japanese rendering of the Chinese character and its radical at every time through single key operation without selecting them on the screen of a display unit.  
     CONSTITUTION: With key F1 of keyboard KB depressed, a Chinese code stored in the FIFO type memory at its top is outputted and displayed on display unit CRT. With key F2 depressed, a Chinese code stored at the 2nd column is outputted and displayed on unit CRT. Similarly, depressing keys F3 and F4 outputs Chinese codes stored at the 3rd and 4th columns. When Japanese such as kan-ji nyu-ryoku no (Chinese in figure: (1) ryoku (2) nyu (3) ji (4) kan) (it means "of Chinese input") is to be inputted while the FIFO memory is stored with "ryoku" at the top column and with "nyu" at the next column in the array of the last inputting, "nyu" can be inputted immediately after F2 key is depressed. Thus, the Japanese rendering, etc., of the Chinese character are inputted at every time through single key operation and are not selected on the display unit, improving the operation.

Title: Constant speed traveling device of vehicle
Inventor: TANIDA HARUNORI
IPC: F02D29/02
Filed: 1995-05-09
Abstract: PURPOSE: To suppress the generation of the realistic sense of reckless driving and sense of sudden deceleration constantly taking into consideration the change in the actual vehicle speed by providing a guard means to achieve the guard so that the changed target vehicle speed is the target value in the prescribed range. CONSTITUTION: A vehicle seed detecting means P1 detects the actual vehicle speed of a vehicle, while a vehicle speed setting means P2 sets the target vehicle speed of the constant speed traveling. A control means P3 controls a speed control mechanism P4 so that the actual vehicle speed approaches the target vehicle speed based on the difference between the actual vehicle speed and the target vehicle speed. An acceleration switch P5 increases the target vehicle speed in the constant traveling, while a deceleration switch P6 decreases the target vehicle speed. A changed target vehicle speed setting means 7 operates either of the switches P5, P6 to set the changed target vehicle speed, while a guard means P8 achieves the guard so that the set changed target vehicle speed is the target value in the prescribed range.  Generation of the sense of reckless driving and sudden deceleration can be excellently suppressed even when the changed target vehicle speed with large difference is set.
