Patent JP-H05157354-A (JP)
Title: Electric hot water supply apparatus
Inventor: KUNIMOTO KEIJIRO
IPC: F24H1/18
Filed: 1991-12-05
Abstract: PURPOSE:To prevent hot water supply from being interrupted while effectually supplying midnight power and daytime power in heating power supply control of a hot water supply type electric hot water supply apparatus. CONSTITUTION:A pattern comparator part 17 compares a standard hot water supply pattern estimated by a standard pattern setting part 16 from the past yielded by a hot water supply pattern storage part 15 with a present hot water supply pattern estimated by a hot water supply pattern estimation part 13. When a supplied hot water supply heat amount exceeds a standard value, daytime power supply control means 19 evaluates a heating amount by daytime power based upon the exceeding heat amount and controls power supply to an electric heater 2. Accordingly, provided the use of hot water supply exceeding the standard hot water supply pattern such as those in occasional morning bathing or sudden visitor, excessive additional boiling is achieved by the daytime power.
Patent JP-H03183130-A (JP)
Title: Manufacture of semiconductor substrate
Inventor: NIEDA AKIRA
IPC: H01L27/12
Filed: 1989-12-12
Abstract: PURPOSE:To eliminate an unbonded part, at the outer circumference of wafers, caused at a pasting operation and to prevent the breakage produced at the outer circumference part of the wafers by a method wherein two wafers are pasted and, after that, their outer circumference is chamfered. CONSTITUTION:Two wafers 1 and 2 are pasted; after that, the outer circumference part of the two wafers 1 and 2 which have been pasted in advance is chamfered. As a result, when the wafer 1 on one side is polished and processed at a posterior process, the peripheral end edge 1a of the wafer 1 on one side is not levitated from the wafer 11 on the other side. That is to say, since an unbouded part is eliminated, a breakage is not produced at the outer circumference part of the wafer 1 on one side. Consequently, reliability of a semiconductor substrate 1d is increased, and the yield of a device formed on the substrate 16 can be increased.
Patent JP-H01200165-A (JP)
Title: Heat pump type air conditioner
Inventor: UMETSU KENJI
IPC: F25B13/00
Filed: 1988-12-22
Abstract: PURPOSE:To provide a heat pump type air conditioner of which capability can be realized during its heating operation and in a silent state by a method wherein some coolant pipes of an outdoor heat exchanger are formed in a row and a diameter of each of the coolant pipes is made larger than that of a coolant pipe for an indoor heat exchanger. CONSTITUTION:A diameter of a coolant pipe of an indoor heat exchanger 5 acting as a condensor when heated is made as a fine diameter. A diameter of a coolant pipe of an outdoor heat exchanger 3 acting as an evaporator is made as a large diameter and then the pipes are formed in a row. Thus, it is possible to reduce a pressure loss of the coolant flowing in the coolant pipe of the outdoor heat exchanger 3 providing a substantial influence and to increase a capability of the heat exchanger during a heating operation. Due to the fact that the diameter of the coolant pipe of the indoor heat exchanger 5 is made small, a substantial loss of flowing pressure is found during a cooling operation. However, the capability can be realized more in case of cooling than in case of heating, resulting in that any particular trouble may not occur. Since the coolant pipes of the outdoor heat exchanger 3 are formed in a row, an aeration resistance is not so increased as compared with a plurality of rows and thus it is possible to get a heat pump type air conditioner having no reduction in performance and producing a silent sound.

In which case, when fluid is fed to the pad 10 (a chamber) and a belt-form substance 20 (a strip) is conveyed in a non-contact state, the levitation height (h) of the belt-form substance from a pad surface is detected. By regulating a flow rate of fluid for levitation according to a change amount of the levitation height (h), control is made such that the levitation height is always maintained at a value within a constant range.

Filed: 1994-12-26
Abstract: PURPOSE: To provide a system low in cost and high in reliability by applying change only to add respective error check mechanisms by duplicating main memory and always storing information of the same content in both main memories. CONSTITUTION: A CPU 3 makes an external data write processing part 4 read in first prescribed program data and numeric data from an external memory device FDD1 or HDD2, and write them on the same addresses of the main memories M1, M2, respectively. In the execution of an intruction, when no error is detected in the parity check of the instruction read out from the main memory M1 on a master side, however, noncoincidence occurs as a result of comparison of the same instruction by reading out from the main memory M2 on a slave side, read/write check processing is performed on both main memories M1, M2. When a read/write error is detected in either main memory M1 or M2, the instruction of the main memory M1 or M2 on a normal side in which no error is detected is executed.
