Title: Needle roller assembling
Inventor: HARAZONO SHIYOUICHI
IPC: B65H31/34
Filed: 1980-04-09
Abstract: PURPOSE: To assemble needle roller precisely by first dropping half the number of needle rollers into an assembler then further dropping remaining half thereinto for them to be forcibly inserted into a bearing case.  
     CONSTITUTION: Needle roller 1 drops into a needle roller storing hole 5 of a storage 6. When a closing plate 8 is rotated horizontally by half a pitch, half the number of needle rollers 1 drop into a bearing case 12. Then a collet 14 is expanded to assemble said needle rollers 1 in said bearing case 12 with an equal pitch. Next, if a assembler 10 is made to rotate horizontally by one pitch, the remaining half of said needle rollers 1 make a drop into the space formed between the first half of the needle rollers to be assembled therein in the same way as the latter. Consequently, the needle rollers can be assembled in an exact manner without failure notwithstanding the presence of a collar for supporting the needle rollers.

Abstract: PURPOSE:To obtain a cooling device having small size and high efficiency by independently forming a closed loop in which cooling medium for a laser power source is flowed and a closed loop in which cooling medium for a plasma discharge tube is flowed. CONSTITUTION:A coil of a relatively low temperature cooling medium passage 30 is disposed under a heat exchanger 10, and the coil 62 of relatively high temperature cooling medium passage 32 is disposed above the heat exchanger. Chilled air is fed from below the heat exchanger 10 via a fan 2 to cool sequentially the low temperature coil 60 and the high temperature coil 62 and exhausted upwardly. In this manner, the coil 60 cools the medium of the loop 30 from 35 deg.C to 30 deg.C, and the coil 62 cools the medium of the loop 32 from 60 deg.C to 55 deg.C by 5 deg.C respectively. In this manner, the power source 4 and a discharge tube 5 respectively become as low as 35, 55 deg.C.

Filed: 1992-03-04
Abstract: PURPOSE:To obtain a highly accurate sensor useful environment conservation by adding a porous thin film having a filter function for passing gas to be detected in a first collecting electrode, and constituting a metal film of a thin film covering the approximately entire surface of one side of solid-state electrolyte CONSTITUTION:A metal film 2A acting as a detecting electrode comprises the mixed body of, e.g. platinum and silver. A solid-state electrolyte 3A comprises RbAg4I5. A second collecting electrode 4A comprises silver. A porous thin film 10 is provided between a first collecting electrode 1 and the metal film 2A by the vapor deposition of platinum. The thin film 10 has the filter function. Gas to be detected G, which has passed through the collecting electrode 1 and the thin film 10, comes into contact with the film 2A, undergoes reaction with silver and becomes silver fluoride. When a constant DC is conducted across the collecting electrode 1 and the collecting electrode 4A, the silver ions are moved into the collecting electrode 4A from the film 2A and deposited. When the silver disappears in the film 2A, the terminal voltage rapidly rises up. The concentration of the gas G can be detected based on the time difference from the start of the current conduction to the voltage rising. Steam and carbon dioxide gas can be directly brought into contact with the electrolyte 3A during this period.
