Title: Static pressure bearing
Inventor: OKADA AKIHISA
IPC: F04D29/04
Filed: 1991-11-07
Abstract: PURPOSE:To maintain stable performance over a long period in a device wherein plural pockets are formed on the inner surface of a bearing cylinder and lubricant is fed to these pockets, by forming a groove in an axial direction, on the inner surface of the bearing cylinder, which does not communicate with pockets but communicate only with the edge surface on one side of the bearing.

Title: One drum two water-channel bath hot-water supply apparatus
Inventor: SATO TETSUYA
IPC: F24H1/00
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To contrive to stabilize the resupplied hot water temperature by suppressing fluctuations in the hot water temperature by additional boiling when resupplying hot water after hot water is used independently. SOLUTION: An operation mode discriminating section 34 discriminates whether or not an apparatus operation is a hot water independent supply operation state. A pump operation time is stored in a data housing section 36. A pump temporary drive means 37 drives a circulation pump 17 only for the pump operating time directly after the combustion stop of hot water independent supply operation and eliminates high temperature water remaining in an additional boiling heat exchanger heated with a burner during sole supply operation of hot water by allowing the hot water to flow out and thereby prevents the high temperature hot water in the additional boiling heat exchanger from being a heating source which boils additionally the hot water in the hot water supply heat exchanger after the stop of hot water independent combustion.  The heat of the hot water supply heat exchanger is absorbed with a low temperature water which flows into the additional boiling heat exchanger by driving the circulation pump 17, thereby inhibiting a rise in the temperature of hot water by additional boiling in the hot water supply heat exchanger and stabilizing the temperature of hot water when hot water is supplied thereto in the next time.

Title: Inspection method of prepreg
Inventor: IIJIMA IKUO
IPC: H05K3/46
Filed: 1991-11-07
Abstract: PURPOSE:To simply estimate the moisture absorption state and the content of volatile component of prepreg, and prevent imperfect form, by heating and pressing the prepreg in a vessel, blocking the flowing-out of resin into the part between the vessel periphery and the prepreg by using the peripheral wall of the vessel, and observing white muddiness and foaming state. CONSTITUTION:A prepreg 2 is stacked on the central part of a vessel 1 made of an aluminum foil and heated and pressed at a pressure of 0.7MPa by using a heat plate 3 kept at a temperature of 170 deg.C. In the vessel1, resin which has flown out from the prepreg is prevented from stretching toward the periphery. The state of resin 4 which has flown out into the part between the peripheral wall of the vessel 1 and the prepreg 2 is observed. The moisture absorption state and the content of volatile component of prepreg which are different on account of storage or kind are simply estimated. Thereby the white muddiness and the foaming degree of flowing-out resin which correspond with the generation degree of voids at the time of molding can be previously known. Hence whether molding is acceptable is effectively estimated, and imperfect molding can be prevented.

Filed: 1991-11-07
Abstract: PURPOSE: To maximize the number of detectable keys and to improve the efficiency by providing plural interface ports to be successively scanned by scanning signals in an interface circuit and providing a register means for receiving the state of the ports from a keyboard interface circuit means and encoding it. CONSTITUTION: This keyboard interface 12 is provided with N pieces of the interface ports and one of the ports is represented by Pi.

When one or more ports Pj are in an active state, the result is stored in a register 13. Then, the register 13 transmits the received state to an encoder 14 for encoding and an operating state is reset to an initial state. All the cycles of detection and scanning operations are ended by that.

Title: Image signal processing circuit
Inventor: KUWAJIMA TAKESHI
IPC: G11B20/06
Filed: 1990-10-29
Abstract: PURPOSE:To cancel the effect of phase shift delay due to a non-linear circuit and a low pass filter, and reproduce an excellent image luminance signal by extracting high pass components before and after de-emphasize processing and conducting phase shift correction on a signal before the de-emphasize processing with the differential output of the signals before and after the de-emphasize processing as a control input. CONSTITUTION:The output of a nonlinear de-emphasize circuit 5 is inputted to a high pass filter 8 to remove DC components. Differential output between the output of a limiter circuit 7 and the output of the high pass filter 8 is obtained by a subtracter 9 to be inputted to a control circuit 11. The control circuit 11 gives a phase shift circuit 10 the operating point of phase shift quantity control with the output of the subtracter 9 as control input. At this time, the control circuit 10 outputs such a control output as to correct the phase shift quantity of the phase shift circuit 10 so that, for instance, the differential output of the subtracter 9 may be zero. Thus, the reproducibility of edge component or the like can be improved.
