Patent JP-H06286985-A (JP)
Title: Hydraulic jack
Inventor: OGAWARA YOSHIKATSU
IPC: B66F3/42
Filed: 1993-03-31
Abstract: PURPOSE:To reduce a force required for operation of a handle by providing a pressure control valve which is constituted to open when a pressure in a second oil passage exceeds a given value and return oil in a second oil passage to an oil tank. CONSTITUTION:When a high load is applied on a ram 4, oil in a second oil passage 35 flows in the lower small part of the stepped through-hole 72 of a sixth oil passage 76. The pressure exceeds a given value and is increased to a value higher than the energizing force of a compression soil spring 82. Thereby, a ball valve body 81 is separated away from a valve seat 79 and a pressure control valve 78 is opened. A second oil passage 35 is brought into a state to be communicated with an oil tank 2 through the sixth oil passage 76 and oil in the second oil passage 35 fed from the large inside diameter part 7a of a pump cylinder 7 flows back to the oil tank 2 after the flow of it through the sixth oil passage 76. Thus, the ram 4 is raised only by oil delivered from the small inside diameter part 7b of the pump cylinder 7 and as a result, a rise amount of the ram 4 per one action of an operation handle is reduced.

Title: Combustion type heat source device
Inventor: HAYASHI FUMIO
IPC: F24D3/08
Filed: 1990-03-23
Abstract: PURPOSE:To reduce a combustion temperature and to reduce the generation of NOx during combustion by a method wherein the flame of a burner is formed between the fins of a water tube type heat exchanger and the flame is cooled by the water tube type heat exchanger. CONSTITUTION:Combustion gas generated through combustion effected by a burner 13 is heat-exchanged directly with hot water, returned through a piping 40 for circulation by means of a gas liquid heat exchanger 32, for heating. In this case, since combustion gas and water are directly heat-exchanged with each other, NOx and CO2 in the combustion gas are dissolved in hot water. Since water heated by the gas liquid heat exchanger 32 is heated by a water tube type heat exchanger 20, the temperature of hot water can be increased to a high value, and high temperature hot water can be circulated to the piping 40 for circulation. Meanwhile, since flame is formed between fins 20b of the water tube type heat exchanger 20, the combustion temperature of the burner 13 is reduced to a low value by means of the water tube type heat exchanger 20. Thereby, an amount itself of NOx generated is decreased.

Title: Developing device in electrophotographic device

IPC: G03G15/06
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To decrease the occurrence of fog on a white base and to obtain a satisfactorily developed image, by removing low electrified toner on a developing roller, which is easily stuck to the white base of an image carrier, at the time of reversal development with two-component developer, and thereafter carrying out development. SOLUTION: A recovering bias is applied to a recovering roller 23 so that the absolute value of its surface potential is smaller than that of the surface potential V0 of a photoreceptor 11. Toner 17a in two-component developer 20 that is small in amount of electrostatic charges and weak in sticking force with respect to carrier 18 is attracted toward the recovering roller 23 and removed from a developing roller 12. Toner stuck to the surface of the recovering roller 23 is scraped off by a recovering blade 24 and recovered. Thereafter, in a developing position, the developing roller 12 develops reversal electrostatic- latent-image on the photoreceptor 11. However, because the low electrified toner 17a is removed from the two-component developer 20, only the sufficiently electrified toner 17 contributes to the development.  Therefore, without being attracted and stuck to an unexposed area (white base part) of the photoreceptor 11, the toner 17 is applied only to an exposed area.
