Title: Manufacture of optical element
Inventor: ISHIBASHI AKIRA
IPC: H01S5/30
Filed: 1990-01-17
Abstract: PURPOSE:To realize a short wavelength band semiconductor laser or a light emitting diode having excellent characteristics by introducing hydrogen into an n-type impurity-doped compound semiconductor layer. CONSTITUTION:Hydrogen is introduced into an n-type impurity-doped compound semiconductor layer 3 to nonactivate an acceptor to be formed in the layer 3 by doping the n-type impurity. Thus, the impurity doped in the layer 3 acts as a doner to obtain an n-type even in the layer 3 which was difficult to obtain the n-type by a self-compensating effect though it has a wide gap. Accordingly, an excellent pn junction can be easily formed by employing a semiconductor substrate 1 formed previously with a p-type compound semiconductor layer 2. Thus, a short wavelength band semiconductor laser or a light emitting diode having excellent characteristic can be realized.

Filed: 1988-01-18
Abstract: PURPOSE:To reduce in size a motor by positioning a rotor magnet with a strong positioning magnet in a movable mold of a rotor, matching the phase of the magnet to that of a sleeve, pouring resin in the mold, and molding the sleeve. CONSTITUTION:A threaded shaft 2 of an insertion component is set to a stationary core C2 by phase positioning with 2 face width flatly cut at two positions at the rounded shaft, and a magnetized ringlike rotor magnet 1 is set to a movable core C1. A rare earth series magnet 3 magnetized in a thrust direction and a positioning block 4 are buried in the core C1. A coil spring 6, a retaining plate 5, and a cap 8 for preventing the plate 5 from flying out are mounted on the core C2 so as not to displace the magnet 1. The core C1 is coupled to the core C2, resin is poured between the magnet 1 and the shaft 2, and a sleeve 7 is injection molded. Thus, the phase-positioning of the magnet and the sleeve is facilitated, and a motor is reduced in size.

Title: Toothed belt
Inventor: ONOE YOSHIFUMI
IPC: F16G1/28
Filed: 1987-01-19
Abstract: PURPOSE:To extend the life of a belt, by sheathing tension bodies having been embedded in a toothed belt on which grooves are formed between belt teeth. CONSTITUTION:The structure of a toothed belt is such that the tension bodies 2 consisting of stranded wires are sheathed to prevent them from being exposed at grooves 4, and that they are embedded in an extension member 6 of the toothed belt 1. Thereby, the exposure of the tension bodies 2 at the grooves 4 can be prevented, and since each tension body 2 is gathered in a bundle by a sheath 3, the damage of strands due to the drawing from a metal mold and the damage due to the separation and fraying of strands caused by the bending of the belt at the grooves while the belt is running can be prevented. Thus, the reduction in the strength of the belt 1 can be prevented, and further the life of the belt 1 can be extended.

Title: Semiconductor device
Inventor: SATO MICHIO
IPC: C22C38/00
Filed: 1987-01-19
Abstract: PURPOSE:To upgrade reliability in a semiconductor device and to obtain this device at its smaller costs, by using a wire material which contains a specific amount of C and O and its remaining part of high purity iron of 99.99 wt.% or more in purity. CONSTITUTION:C is segregated in a crystal granular field by adding it in a minute amount, and C functions to delay recovering of transition and shifting of the granular field during recrystallization so as to raise a temperature of recrystallization and so as to prevent granular field breakage of an iron wire, however, too excessive amount of C promotes propagation of transition and hence performs process-hardening, so that a semiconductor chip becomes damaged. Therefore, the amount of addition is made to be 0.5 wt.ppm to 90 wt.ppm. O in iron is segregated in a crystal granular field so as to reduce expansion of breakage, and further oxide is formed to easily cause a drop in strength so that an iron pole becomes peelable. Hence, O is made to be 10 wt.ppm or less. An electron beam floating band fusion refining process is performed for commercial high purity iron in a superhigh vacuum, and thereafter this iron is cemented by a heating process at 650 deg.C for 5hr to 30 hr in a mixed gas of methane and hydrogen, and casting lumps of high purity iron containing a specific amount of carbon and oxygen as aforementioned are manufactured. Next, each casting lump is chamfered and next extended to be formed into a bonding wire of up to 25 mum in diameter by drawing processing.
