Title: Laminated sheet for electricity
Inventor: SUZUKI SHIGEO
IPC: B29C70/06
Filed: 1988-09-02
Abstract: PURPOSE:To prevent the generation of a concavity warpage in the ordinary state of a laminated sheet for electricity and at a time of working a printed circuit plate by making the weight of glass fabric in the glass fabric impregnated with resin in a metallic foil side larger than the weight of glass fabric in the glass fabric impregnated with resin on the side opposite to the metallic foil. CONSTITUTION:The weight difference of glass fabric in the glass fabrics impregnated with resin in both a metallic foil side and the side opposite to the metallic foil is preferably regulated to 50 - 150 g/m<2>. In other words, the improvement in the elimination of warpage is difficult when the above-mentioned weight difference is less than 50g/m<2> and such a tendency that moldability is deteriorated is caused when the weight difference of glass fabric exceeds 150g/m<2>. As the paper to be impregnated with resin to be utilized, kraft paper, linter paper and blended paper of kraft and linter, etc., are preferable. As glass fabric to be impregnated with resin, glass woven fabric, glass nonwoven fabric and glass paper, etc., are recommended. As resin to be impregnated thereinto, phenolic resin, melamine resin, epoxy resin and unsaturated polyester resin, etc., are utilized and it is desirable that epoxy resin excellent in heat resistance and balance in mechanical strength is adopted. As the metallic foil, each individual metal or alloy of copper, iron, aluminum, nickel and zinc, etc., can be utilized.

IPC: H02K9/08
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To equivalently cool both side parts relating to a center surface in an axial lengthwise direction of a stator, by setting a mounting angle of a fan blade of an axial fan mounted in a mounting side of a rotational part of an exciter device to an angle larger than a mounting angle of a fan blade of an axial fan mounted in an opposite exciter device side.

A blade angle α2 of an axial fan 31A is set larger than a blade angle α3 of an axial fan 31B. In this way, a side of the exciter device 4 and a side of the opposite exciter device 4 relating to the center surface Y-Y in an axial lengthwise direction of a cylindrical rotor 8 can be cooled substantially in the same condition, a temperature rise value of a rotor winding 83 can be equivalently obtained in both sides relating to the center surface Y-Y.

Title: Control method for dam discharge rate
Inventor: ABE TOSHIFUMI
IPC: G05D9/12
Filed: 1990-08-24
Abstract: PURPOSE:To prevent the excess discharge of a total discharge rate or a discharge lack so as to improve reliability and safety by continuously switching the discharge rate between fine adjustment and rough adjustment gates. CONSTITUTION:A target discharge rate distribution circuit 83 distributes a total target discharge rate Qm into the target discharge rate Qmf of the fine adjustment gate 41 and the target discharge rate Qmr of the rough adjustment gate 42 in accordance with a maximum possible discharge rate Qmfm decided in a decision circuit 86 and a present discharge rate Qo. When the distribution of the target discharge rate for respective gates terminates, the discharge control parts 84 and 85 of respective gates generate necessary gate start signals df and fr from the distributed target discharge rates Qmf and Qmr and present gate openings Pf and Pr. Thus, gate driving devices 61 and 62 are controlled to set the discharge rates of respective gates to become the target values Qmf and Qmr. When an inflow rate Qin continuously increases and a flowing water level of dam Hu exceeds the upper limit of a dam water level maintenance area [Hs], the target discharge rate Qm is increased again. Thus, the flow rate can be controlled without the discontinuous change of opening and the disturbance of control owing to the difference of gate opening/closing time and gate friction can be prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a sampling frequency conversion device that becomes small in circuitry scale and efficient. SOLUTION: In a ring buffer 32 data of a sampling frequency of 14.318 MHz successively stored based on the NTSC system. A selector 36 (36a and 36b) reads out data of a memory address specified by address tables 35a and 35b at 13.5 MHz of the sampling frequency, based on a CCIR601 system and supplies it to an interpolation computing element 38. The interpolation computing element 38 multiplies a coefficient supplied by coefficient tables 37a and 37b to two data from the selector 36, adds these multiplied data and then outputs them. The memory address specified by the address tables 35a and 35b and the coefficient supplied by the coefficient tables 37a and 37b are defined on the basis of the ratio of the sampling frequency 14.318 MHz of input data to the 13.5 MHz sampling frequency of output data.

An SCF is formed an anisotropic conductive layer 30B on a base film 30A. When the IC 10 is lowered, the IC10 sinks to the ACF 30 and a cushion material 40A on the transfer stage 40 is deformed. By increasing the heat tool 20 after heating for a specific amount of time, the AC layer 30B is released from a base film 30A from an IC edge part 11 and the AC layer 30B is transferred to the IC 10. By heating and pressing the AC layer (conductive layer) 30B from an object to be transferred, the AC layer 30B is transferred by only a required area.

Title: Instruction fetching system
Inventor: KAMISAKA YUJI
IPC: G06F9/26
Filed: 1986-09-19
Abstract: PURPOSE:To shorten processing time by executing a microinstruction operation for detecting page crossing and a microinstruction operation for counting up and address value stored and IA part by means of hardware. CONSTITUTION:If page size is 4k bytes e.g. when a carry flag is generated from an instruction fetch address part (IA)211, page crossing is detected by a page crossing detecting circuit 22 if all 12 lower bits of the IA211 are '1', and the time of end of an RQF microinstruction, said detection is set up in a flip flop (FF)23. At the time of detecting the page crossing by the circuit 22, the detection is set up in the FF23 and an output, i.e. a page crossing signal, from the FF23 is sent as an ON signal. The page crossing signal informs an inhibition command that the value of the IA211 must not be directly set up in an address register (SAR)17 under the RQF instruction and a main storage device 2 must not be directly accessed by the set value. Consequently, the number of microinstructions and the number of microsteps can be reduced and the processing time can be reduced.
