Title: Thermal deformation absorbing mechanism of centrifugal pump for high temperature water
Inventor: UEYAMA YOSHIHARU
IPC: F04D29/58
Filed: 1985-03-25
Abstract: PURPOSE:To prevent water leakage from inside a pump caused by an decrease in a tightening pressure of a gasket by providing a deformation absorbing mechanism which devides a cylindrical wall at the outer diameter of a cooling chamber and connects the divided walls with bellows for absorbing thermal deformation of a casing cover. CONSTITUTION:A cylindrical wall at the outer diameter of a shaft enclosing cooling chamber 7 is divided at the vicinity of a gasket 4 and bellows 9 are disposed between the divided walls. Thus, when a water temperature in a pump changes abruptly, the wall of the cooling chamber 7 which is located nearer to the inside of the pump than the bellows 9 is thermally deformed due to the temperature change. However, since a casing cover 2 is divided with the bellows 9, a casing cover portion (an outside diameter portion of the gasket 4) which is tightened to the casing 3 with bolts is thermally deformed following to the thermal deformation of the casing 3. As a result, even if the water in the pump is subjected to a temperature change, the pressure applied to the tightened face of the gasket 4 does not change to keep airtightness of the gasket 4 so that the water in the pump is prevented from leaking to permit the pump to operate safely.

Title: Surface emitting semiconductor laser and manufacture thereof
Inventor: KONDO TAKAYUKI
IPC: H01S5/00
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To avoid deteriorating the element by a means such that at least a part has a protrudent resonator and opening at the top face of the resonator and an embedded metal layer of a specified melting point or less is formed to closely contact a top electrode continuously formed along the resonator and an insulation film surface. SOLUTION: A main heating source for the surface emitting semiconductor laser having a protrudent resonator structure is the Joule heat of the resistance of an n-type semiconductor multilayer reflection layer 106 or a contact resistance of a p-type contact layer 107 and top electrode 110. These heat sources exist mainly at a resonator protrusion 108. By embedding the resonator protrusion 108 in a good thermal-conductivity embedding layer 112, the embedding layer 112 acts as a heat sink to accelerate the heat radiation of the resonator protrusion 108, thereby lowering the temp. of the resonator and thus the deterioration of the element can be avoided. To closely imbed the resonator protrusion 108, the heat treating temp. is set so as not to exceed 400 deg.C.

Title: Acoustic reproducing device
Inventor: IDE KENICHIRO
IPC: H04R5/02
Filed: 1990-03-08
Abstract: PURPOSE:To locate a sound image to an optimum position automatically by detecting a listening point of a listener based on an output from a seat position detection means of a power seat and applying arithmetic processing to an acoustic signal so that the sound image is located to the listening point. CONSTITUTION:A control section 15 outputs seat position detection information to a control section 7 from a storage area storing a current seat position and attitude. The control section 7 based on the received seat position detection information calculates a listening point of a listener and sets an arithmetic constant and an arithmetic coefficient in a digital signal processor 1 so that the sound image is located to the listening point. Thus, an acoustic reproducing device 2 detects the position of a seat 13 and the attitude from a control section 15 of a power seat, varies the arithmetic constant and coefficient in the processor 1 in response to the result of detection and locates the sound image automatically to the listening point of the listener. Thus, it is not required for the listener to make complicated operation to adjust the location of the sound image and the operability and the function performance are improved.
