Ni or Co 0.05W0.5% is melted in an inert gas atmosphere and cast in a metal mold. Since this alloy is very brittle, it is crushed to flakes of 1mm or less in thickness with a rolling mill. This powder is heated in air at 700°C for 60hr. to selectively oxidize the Bi, In and Sn, thereby dispersing oxide particles of In 2 O 3  and Bi 2 Sn 2 O 7 . This  material is then converted into chips of 0.2mm or less in thickness, washed, filled in  a tubular mold, press-molded, and sintered at 780°C. This sintered body is further  sintered under press., worked into a wire rod of 3mm in diameter by warm extrusion at 550°C, and finally annealed at 700°C for 1hr. to obtain an electrical contact  pin.

Title: Reservoir tank for master cylinder
Inventor: SUZUKI TOSHIO
IPC: B60T11/26
Filed: 1990-02-22
Abstract: PURPOSE:To prevent production of defectives such as a liquid leak by providing a port communicating with an oil liquid port on one side of a master cylinder at the front side chamber of a reservoir tank main body, and providing a port to communicate with an oil liquid port on the other side of the master cylinder close to a partition wall of the back side chamber. CONSTITUTION:If a defective is produced in a secondary system with which a second chamber 25 communicates, oil liquid in the chamber 25 and a small chamber 34 is eliminated, leaving oil liquid only in a primary system for oil liquid in a main body 22, and its quantity is reduced to the height of a partition wall 23 of a small chamber 33 communicating with a first chamber 24 to be maintained there. When a brake pedal is stepped in this condition, oil liquid in the chambers 24, 33 goes over the partition wall 23 to flow into the chamber 34 to decrease oil liquid in the chambers 24, 33. If the brake is stepped in this condition, oil liquid moves to the front side in the chamber 24 for every step, leaving only a small quantity of oil liquid on the back side, but because a port 27 to a master cylinder exists on the front side, oil liquid is covered with the port 27 constantly, thereby penetration of air from it can be prevented.

Title: Detector for semiconductor element position
Inventor: FUJIMORI YASUTOMO
IPC: H01L33/00
Filed: 1978-04-13
Abstract: PURPOSE: To detect the position of a semiconductor element by irradiating the element with light of selected wavelength and by making use of light of different wavelength emitted as a result of irradiated-light absorption.  
     CONSTITUTION: On semiconductor element 1, a light spot of mean wavelength (λ 1 ) selected is projected from exciting light source 2. Although light of mean wavelength (λ 2 ) is emitted from element surface 11 through irradiated-light sbsorption, no light is emitted from electrode surface 12. In addition to directly-reflected light, scattered light and ambient light, this light (λ 2 ) is focused by lens system 3 to allow light of wavelength (λ 2 ) to pass through BPF4. At the arrangement center of quadri- division detector 5 provided with photo detection elements 51 to 54, the light flux passing through the BPF forms the semiconductor-element image, and element 1 is moved to equalize four detected light quantities, thereby grasping the element position according to the electrode position. By this method, the SN ratio of position detection is remarkably high.
