Title: Manufacture of whisker-reinforced al or al-alloy composite material
Inventor: MORIMOTO HIROYUKI
IPC: C22C47/14
Filed: 1987-01-19
Abstract: PURPOSE:To efficiently compact the titled composite material, by filling a mixture of whiskers and Al into a capsule, subjecting the capsule to vacuum deaeration and hermetic sealing, and applying hot isostatic pressing under specific conditions. CONSTITUTION:The mixture of whiskers and Al or Al alloy is filled into a capsule, and the inside of the capsule is subjected to vacuum deaeration to undergo hermetic sealing. Subsequently, at the time of carrying out HIP treatment, pressure rise is controlled, until temp. reaches a region between the solidus temp. of Al or Al alloy and a temp. lower than the above solidus temp. by 60 deg.C, so that pressure does not rise in the course of temp. rise or, even if elevated, it does not reach compacting temp. Temp. is controlled to a value below this solidus temp. until compacting is completed and, as to the depressions of temp. and pressure after the completion of sintering carried out at a temp. between the solidus temp. and a temp. below the liquidus temp. of Al or Al alloy, control is carried out so that pressure at the time of sintering is maintained until a temp. lower than the solidus temp. is reached. In this way, the occurrences of capsule shrinkage, whisker breakdown, etc., at the time of compacting can be prevented.

Title: Controller of semiconductor switch
Inventor: MIMURA MUNEHIKO
IPC: H02M1/06
Filed: 1978-02-02
Abstract: PURPOSE: To attain the definite and rapid commutation of a thyristor with a transformer miniaturized by widening the in-use range of the transformer and by suddenly attenuating the collector current of a commuting transistor.  
     CONSTITUTION: Driving signal S g 1 supplied to auxiliary transistor QC1 is cut off to turn QC1 OFF and at the same time, supplying driving signal S g 2 to QC2 and QC3 turns QC2 and QC3 ON to supply a sufficient reverse bias voltage between the base and emitter of commuting transistor QM. As a result, the voltage of winding N11 is supplied reversely between the emitter and collector of QM through DA and CA as absorbers, thereby turning QM OFF immediately. Once the magnetic cores of transformers T1 and T2 are saturated, QC2 and QC3 both turn OFF and the magnetic flux reaches point PM. Therefore, the in-use range of the transformers can be widened, miniaturization is realized, and definite and rapid commutation is made through the smooth turning-OFF of the commutating transistor.

Title: Voltage back coupling type josephson circuit
Inventor: KODERA NOBUO
IPC: H03K19/195
Filed: 1982-01-29
Abstract: PURPOSE:To obtain a logical circuit which can be driven by a DC power supply and produces no hang-up, by having a loop connection among two Josephson devices and a resistance with a DC power supply and defining the contact of the loop as a supply point of power supply. CONSTITUTION:A hang-up phenomenon may possibly occur with a circuit shown in the diagram. To avoid this phenomenon, a bias current is supplied through a terminal B2 of a bias control line of a device J2, and the J2 is kept in a voltage state in a non-signal input mode. This is not necessarily required for a terminal B1 of the bias control line of another device J1. Furthermore two device signal input terminals S1 and S2 are connected directly to each other (shown by a dotted line in the diagram) so as to be driven by a common input current. Thus an input current is so set as to flow in an opposite direction to the bias current which is supplied to the terminal B2. As a result, the circuit can be used as a logical circuit without hang-up phenomenon.

Title: Thermal stress reducing pad, thermoelectric transducing system using the same and peltier cooling system
Inventor: KANBE MITSURU
IPC: H01L35/34
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of adjusting a junction or pressing force and guarantee a good conduction of heat and reduce thermal stress by filling a porous matrix with fibers made of such material as to have a high thermal conductivity. SOLUTION: A thermal stress reducing pad 1 can be made just by filling a matrix 2 with fibers 3 oriented in the thickness direction of the pad, that is, the direction in which heat needs to be transmitted, and then hardening the matrix 2. In other words, the thermal stress reducing pad 1 can be manufactured not only easily but also at low cost. Moreover, this pad 1 needs not to be joined either to a thermoelectric transducing unit 4, a heating duct 7, or a cooling duct 8 and therefore the entire power generation system can be assembled easily and replacement of the thermoelectric unit 4 can be facilitated. And, the pad 1 can be provided with a good thermal conductivity characteristic since the porous matrix is filled with the fibers made of such material as to have a high thermal conductivity.

Title: Semiconductor integrated circuit device
Inventor: FURUYAMA TOORU
IPC: G11C11/408
Filed: 1979-02-06
Abstract: PURPOSE:To control a change of the substrate potential by providing a capacitance between the substrate terminal and the grounding terminal. CONSTITUTION:The MOS dynamic RAM2 and the MOS capacitance-group 3 for preventing a change of the substrate potential are formed on the silicon substrate. The RAM2 is composed of MOS FETs and MOS capacitances. In the MOS capacitance-group 3, three MOS capacitances 4 the thickness of each insulating film of which is approximately equal to that of the gate film of the RAM2 are arranged in parallel and the total capacitance is greater than any capacitance of each MOS FET or MOS capacitance of the RAM2. The grounding potential Vss is applied to the capacitance 4, the potential VBB on the order of -2 volts is given to the substrate by the substrate potential self-generator. Also the potential VDD of about 5 volts is applied to the drain of the FET of RAM2. In this way, even through the substrate current IBB is changed by a selective on-off operation of the FET, a change of the substrate potential VBB can sufficiently be absorbed since the total capacitance of the capacitance-group 3 is greater.

Title: Solid and liquid separator of raw water such as sludge
Inventor: KANO MASATAKE
IPC: B01D21/08
Filed: 1987-01-21
Abstract: PURPOSE:To effect efficient solid and liquid separation and miniaturize the subject device by conducting a mixture of raw water and flocculant into a cylindrical separation tank into a flocculation tank to permit the mixture to circulate slowly, then allowing flocks to grow actively on the inclined surface of separation elements with a final process to separate the solid and liquid in a precipitation/separation chamber. CONSTITUTION:In a solid and liquid separator consisting of a flocculation tank 4 with an open top, an inclined separation chamber 2 with a plurality of umbrella-like separation elements 13 and a precipitation/separation chamber, housed in a cylindrical container, a mixture of flocculant and raw water is fed into the flocculation tank 4 to allow its slow circulation and conversion into smoothly precipitating flocks. Next, flocks are allowed to grow and separate by friction resistance on the inclined surface of the separated elements 13, and the flocks flowing into the precipitation/ separation chamber 3 are further concentrated. These concentrated flocks are discharged from a sludge discharge pipe 22. In the meantime, the supernatant collected in the collection chamber 13 and the collection part of the separation elements is discharged through a supernatant discharge pipe 11. In this way, almost all of the mechanical operation part is eliminated and further efficient solid and liquid separation and miniaturization of the device are realized.

Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To speed up pressing by detecting the distance from the search drive start point of a ram with respect to a work to a contact recognition point and changing the search drive start point to a position nearest the work from a standard deviation with respect to the average value thereof. SOLUTION: The press is provided with a central arithmetic processing unit and the pressing is executed by controlling a drive motor of the ram 30. At this time, the ram 30 is lowered from the approach drive start point 1 on the lower side of the upper limit position at a high speed down to the search drive start point 2 where the ram is decelerated and is brought near to the pressurization drive start point 3 at a low speed by the respective control means attached to the press. In succession, the ram is so actuated as to execute the pressing of the work W from pressurization drive start point 3 with a prescribed torque, to complete the pressing at a pressurization end point 4 and to return again to the approach drive start point 1.  The drive start point 2 is changed to the position closer to the work W according to the progress of the pressing by a standard deviation computing apparatus and a search drive start point changing apparatus. The higher speeding up of the press is thus made possible.

Title: Cad/cam device
Inventor: NAKADA MASAFUMI
IPC: G05B19/4093
Filed: 1993-01-28
Abstract: PURPOSE:To generate a machining path which is free from any insufficient cutting despite a large cutting amount of a tool by providing a means which produces an offset curve having an offset larger than the precedent one by the tool cutting amount and a means which adds a loop to the graphic element at the corner part of the offset curve. CONSTITUTION:An offset part 13 generates an offset curve to offset a machining shape curve by an amount equal to the radius R of a tool or to offset the precedent curve by an amount equal to the tool cutting amount (r). A corner loop adding part 14 adds a corner loop to the graphic element at a corner part of the offset curve. A deciding part 15 compares the amount (r) with the radius R to decide the adding propriety of the corner loop. Thus, a machining path generating part 17 generates the present machining path according to the offset curve and the graphic element having a corner loop. A miscutting deciding part 16 offsets the precedent offset curve by an amount equal to the radius R and discriminates the insufficient cutting from the cutting curve crossing the corner part and the curve offset by an amount equal to the amount (r).
