Title: Buffer device of belt cleaner
Inventor: HAMAMOTO IZUMI
IPC: B65G45/12
Filed: 1983-03-02
Abstract: PURPOSE:To heighten the efficiency of scraping off a load with a scraping plate by coupling an elastic part to one end of a level rotatably supported in an apparatus in which the scraping plate is fixed to the other end of the lever and the scraping plate is pressed against a conveyer belt. CONSTITUTION:A conveyer belt 2 wrapped round a pulley 1 is rotated in direction of an arrow A to carry a load 3. A lever 5 is supported by a shaft 6 in the vicinity of the conveyer in such a manner as to freely turn vertically, and a scraping plate 4 is fixed to one end of the lever 5. In this arrangement, the upper end of a rope 9 is coupled to the other end of the lever 5, and the lower end of the rope 9 is coupled to th midway of an auxiliary lever 12. One end of the rope 9 is supported by a shaft 10 in such a manner as to turn vertically, and a weight 7 is fixed to the other end of the lever 12. In this arrangement, when a load 3 adhering to the conveyer belt 2 is scraped off by the scraping plate 4, vibration applied to the scraping plate 4 is absorbed by elasticity of the rope 9 and friction produced at the shafts 6, 10 to improve the scraping efficiency.

Title: Method for diffusing zinc in compound semiconductor
Inventor: MUROFUSHI HITOSHI
IPC: H01L21/223
Filed: 1993-01-28
Abstract: PURPOSE:To prevent the crystallinity deterioration of a compound semiconductor near a p-n junction so as to obtain a high light emitting efficiency by starting the heating of a substrate containing unbaked silicon oxide and phosphor oxide under the presence of steam containing zinc as an impurity and continuing the heating. CONSTITUTION:An unbaked film 2 is formed by forming a film by dropping a glass film forming liquid containing SiO2 powder and P2O5 powder onto the surface of an n-type GaAsP semiconductor substrate l while the substrate 1 is rotated and vaporizing a solvent. Then, after putting the substrate 1 with the film 2 in an ampule 3 together with a board 4 and sealing the ampule 3 after providing an ZnAs2 source 5 and P2 source 6 in the ampule 3, the film 2 is heated to about 700 deg.C so as to obtain a vitrified film 2a. When the heating is further continued, the Zn in an area near the surface of the substrate 1 is diffused in the substrate l0. When the diffusing treatment is continued for about 200 hours, the depth (x) to a p-n junction becomes about 10mum and the concentration of the Zn impurity becomes lower near the p-n junction.

Title: Rotary compressor
Inventor: YOSHIMURA TAKAO
IPC: F04C18/356
Filed: 1989-02-13
Abstract: PURPOSE:To reduce a leakage loss of lubricating oil as well to improve the extent of volumetric efficiency by installing plural recesses decreasing each sectional area to one side rotational direction along the circumferential direction and also plural recesses increasing each sectional area respectively in each end face being opposed to both main and sub bearings of a roller. CONSTITUTION:A rotor 19 moves its revolution with a center O2 of a crank 3c turned around a center O1 of a shaft 3, while it moves its rotation in both clockwise and counterclockwise directions with the center O2 as the center. When lubricating oil reached to both end faces 19a, 19b of the rotor 19 flows into recesses 20a - 20d and 22a - 22d increasing each sectional area due to the revoluting motion, oil pressure goes up owing to a wedge effect. When the rotor is rotated clockwise, if the lubricating oil flows into these recesses 20a - 22d and 22a - 22d increasing each sectional area, the oil pressure goes up as well. Even in the case where the roller 19 is rotated counterclockwise, the oil pressure goes up too. Since the number of recesses is the same, each hydraulic power is balanced, and thereby an amount of oil flowing into a compression space and a suction chamber is reduced. Thus, even in low speed operation, the hydraulic power is produced owing to the rotation.
