Title: Ohmic contact formation
Inventor: OOTSUKA NAMIKI
IPC: H01L21/28
Filed: 1987-07-23
Abstract: PURPOSE:To minimize the variability of contact resistance for improvement of the reproducibility of the contact resistance by a method wherein a Ge film exceeding a half in thickness of an Au film is formed on the Au film and an Ni film is formed on the laminated structure. CONSTITUTION:An ohmic contact is made with the surface of an n type compound semiconductor layer 1. At this time, an Au film 2, a Ge film 3 and an Ni film 4 in thickness exceeding a half of the thickness of Au film 2 are laminatedly formed on the ohmic contact making region. The film quality is kept constant by controlling the ratio of Au to Ge as well as the film thickness thereof.

Abstract: PROBLEM TO BE SOLVED: To form a semiconductor light emitting element in a high integration by forming a temperature sensor on a semiconductor layer, thereby holding a temperature difference between an element for measuring a temperature and the emitting element constant, and holding a thermal stress therebetween small. SOLUTION: A sub-mount 3 and an insulator board 7 are formed on a heat sink 5. A second conductivity type semiconductor layer 20 is formed on the board 7. A semiconductor light emitting element 1 is formed at a left side and a temperature sensor 2 is formed at a right side on the layer 20 as a common substrate. The sensor 2 has a structure in which conductive thin films 13 are connected in series between electrodes to measure a potential difference between the electrode 11 and the electrode. A main difference between the element and a conventional light emitting element is that the sensor 2 and the element 1 are commonly formed on the layer 20. Thus, a temperature difference between an element for measuring a temperature and the element 1 can be held constant.

Inventor: SAITOU YOSHIO
IPC: G03B27/50
Filed: 1981-11-18
Abstract: PURPOSE:To operate no brake despite of the input of a brake signal and to prevent the occurrentce of a collision by a method wherein a brake driving circuit is made ineffective by an input control circuit while a counter electromotive force current is flowed into a clutch operating solenoid. CONSTITUTION:A TR1 is turned ON by the input of a high-level clutch signal and a clutch operating solenoid SOL1 is instantly magnetized and when the clutch signal is changed to low level, the TR1 is instantly turned OFF to demagnetize the SOL1. Counter electromotive force is produced at the same time of the demagtnetization, and a counter electromotive force current flows through a ZD1, a TR3, and an R1 while the voltage at the collector side of the TR1 exceeds Zener voltage and a TR5 is turned ON. Therefore, a brake driving circuit 28 becomes ineffective despite of a brake signal. When no counter electromotive force current flows, the TR5 is turned OFF and the brake driving circuit 28 is turned ON by a high-level brake signal and a brake operating solenoid SOL2 is magnetized.

Title: Production of aluminum alloy casting
Inventor: HARADA TOKUFUSA
IPC: B22C9/10
Filed: 1994-08-08
Abstract: PURPOSE:To improve the collapsibility of a core after pouring molten metal by blending curable organic binder into molding sand containing a specific amount of refractory granular material with high sp. gr. having true sp. gr. of a specific value and forming the core. CONSTITUTION:The curable organic binder is blended into the refractory granular material with high sp. gr. having true sp. gr. of >= 3.4 or the molding sand containing >=10% the above granular material to form the core. An aluminum alloy casting is cast by using this core. After casting, the core is removed by giving the casting vibration. In the casting of the aluminum alloy, as sufficient heat histrory for decomposing the binder in the core is not given, the core is difficult to collapse. At the time of using the granular material having the true sp. gr. of >=3.4, the vibrating propagation effect is improved and the core is collapsed. The refractory granular material with high sp. gr. is desirable to use e.g. zircon sand, chromite sand, blast rushed converter slag, granular iron, etc.

When to release, the cord 3 is pulled outward, and the before mentioned pressing power is eliminated, and the cord 3 can be wound. In accordance with the above stated method the stopping position can be selected freely because the working amount of the cord is small and the noise can be prevented by the elimination of a sliding object.
