Title: Insulated gate type semiconductor device incorporating control circuit
Inventor: SAKAMOTO MITSUZO
IPC: H01L27/04
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To enable high-frequency operation of an insulated gate type semiconductor device which incorporates such a control circuit as an overheat protection circuit or an overcurrent protection circuit. SOLUTION: A MOS FET 22 is connected at its drain to a gate terminal 11, at its source to a gate 70 of a power MOS FET 13, and at its gate to a drain terminal 12 through a resistance 41. When it is desired to turn on the power MOS FET, that is, when the drain element is at high potential, a gate voltage of the MOS FET 22 is also at a high potential. Thus, application of the voltage to the gate terminal enables the power MOS FET to be turned on at a high speed. When it is desired to cut off the power MOS FET even at the high potential of the gate terminal, a MOS FET 23 is turned on to increase an on-resistance of the MOS FET 22. Thereby the power MOS FET can be cut off at a high speed even when the driving ability of a MOS FET 24 is low.

Title: Semiconductor device
Inventor: WATANABE HISAO
IPC: H01L21/768
Filed: 1989-11-08
Abstract: PURPOSE:To easily adjust the variance in the wiring length by providing a threshold level voltage variable means setting variably a threshold voltage of a basic element of plural input circuits, and adjusting the threshold voltage of the threshold level voltage variable means. CONSTITUTION:When a threshold level VT of an element having a prescribed rise time is high, the signal inversion slows down, when the level VT is low, the signal inversion is quickened. Thus, even in the presence of variance in the input signal wiring length of the element, the level VT is set variably to absorb the variance. When input points a-c of a logic element 4 have the same threshold level VT0, the rise timing of the input points (b), (c) has a deviation in times t1, t2 with respect to the timing T0, respectively, but the deviation in the rise time is eliminated by correcting threshold levels VT0, VT1, VT2.

Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent measurement error due to outer wind by fixing an open skirt hood to the top of a Venturi stack so that the lower fringe part of the hood is below the upper fringe part of a duct. SOLUTION: The Venturi stack 15 comprises a Venturi tube 2 produced by constricting the intermediate part of a tubular duct 1 and measures the flow rate of passing air based on the pressure in a static pressure hole 10 prior to constriction and the pressure in a static pressure hole 11 at a constricted part.

Title: Pla circuit
Inventor: KITAMI TAKAHIDE
IPC: H03K19/0948
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To shorten delay time by connecting a diode between one of between a power source and a load and between the load and plural nMOS transistors in the forward direction from the power source side to the side of the plural nMOS transistors. SOLUTION: A diode D1 is connected between the power source Vcc and the load resistance 1 in forward direction from the power source Vcc side to the load resistance 1 side, and the nMOS transistors A1 and A2 are connected serially between the other end of the load resistance 1 and GND. When the nMOS transistor A2 is on and the nMOS transistor A1 is off, the potential Vd of a point Bd is to be lower than the supply voltage Vcc by the forward directional voltage drop Va of the diode D1 . The potential V1 of the point B1 turns to High. However, since in the potential V1 of the point B1 the on/off state of the nMOS transistor is lower than the gate input voltage of the nMOS transistor A2 by the voltage drop Vd portion by the diode D1 , also a voltage Vgs applied between the gate and source of the nMOS transistor A2 is ensured only for Vd.

IPC: F24F3/147
Filed: 1991-11-08
Abstract: PURPOSE:To hold balanced air supply and exhaust quantities by providing a duct chamber installed to a heat exchanger, an exhaust suction port, an air supply blow-off port and a wind direction board. CONSTITUTION:A part of air introduced into a duct chamber 70 from a chamber 1 by way of a ventilation duct 60 is exhausted outdoors by way of exhaust air passages 86 and 87. The remaining air is circulated into the chamber 1 from an indoor blow-off port 64 by way of an air conditioner 5. The supplied air introduced into a duct chamber 70 from an air supply blow-off port 92 by way of a heat exchanger 9 from outdoors is introduced into the chamber 1 from the indoor blow-off port 64 by way of the air conditioner 5. A part of air introduced into the duct chamber 70 is absorbed positively into an exhaust suction port 91 by means of a wind direction board 80 and exhausted. This construction makes it possible to inhibit a reduction in the amount of exhaust air induced by an air flow in the duct chamber 70 and balance the amount of supply air with the amount of exhaust air.

Title: Ski pole
Inventor: KANAMARU TATSUMI
IPC: A63C11/00
Filed: 1987-11-18
Abstract: PURPOSE: To make a pole lightweight and make it easy to flex, by providing a layer, as a pole external-layer, in which wholly aromatic polyester fiber cloth is fixed with resin. CONSTITUTION: A plurality of fiber layers fixed with resin are integrally bonded to each other from the inside of a ski pole to its outside, and, in the external layer, wholly aromatic polyester fiber is fixed with the resin. Preferably, carbon- fiber unidirectional material is fixed with the resin as the internal layer, and glass-fiber unidirectional material or cloth is fixed with the resin as the intermediate layer. This prevents the external-layer fiber of the surface from bending or becoming nappy even when the pole flexes greatly, and also makes its weight sufficiently light in comparison with that of a stock made of aluminum alloy.

Title: Manufacture of bonding wire
Inventor: MORITA AKIYASU
IPC: H01L21/60
Filed: 1988-11-18
Abstract: PURPOSE:To reduce the rate of wire breakdown and improve corrosion resistance by processing a high purity Al stock material into one having a specific diameter by processing the same by a hydrostatic wire drawing process such that an area ratio per a single processing is more than a specific value. CONSTITUTION:A 99.99% or more high purity Al stock material is processed by a hydrostatic wire drawing process such that an area ratio per single processing is 1.5 or more, to provide a bonding wire having several tens of mum. In the hydrostatic drawing wire process, pressure P is exerted on a wire material 1 through a pressure medium 3 to force out the wire material 1 from a die 3 for expansion and contraction of the same. With high purity Al, satisfactory corrosion resistance is assured. With application of a hydrostatic drawing wire process, wire breakdown is avoided together with the improvement of corrosion resistance. Further, with an area ratio per one time processing being made 1.5 or more, pressure processing is allowed to microcrystalize.
