IPC: H03K17/16
Filed: 1990-10-08
Abstract: PURPOSE:To set up the driving capacity of logic cells at the optimum value for avoiding the increase in the power consumption and noise by a method wherein a bias voltage separating means generates the bias voltage for setting up current value while a current value limiting means limits the value of the current running between the first and/or the second reference potential source and logic cells to the value not exceeding the set up value by the bias voltage. CONSTITUTION:The current values running in the N channel MOS transistors 13 comprising respective variable current sources 10a-10c can be controlled by the bias voltage VB fed through the intermediary of a bias line 12. The bias voltage generating circuit 11 uses the voltage VGS between gate.source of the transistor 15 generated when a rated current IB is fed from a rated current source 14 to the transistor 15 as the bias voltage VB. Through these procedures, the transistor 15 and the transistors 13 in respective variable current sources 10a-10c can compose so-called a current mirror circuit.

Title: Hot-water supplying system
Inventor: WATANABE TAISUKE
IPC: F24D17/00
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent the fluctuation of the temperature of discharged hot water and permit the obtaining of stabilized hot water by a method wherein the supply of cool water to a bathtub side selectively without passing through a heat exchanger is permitted when supplementing cool water into the bathtub. SOLUTION: In a hot-water supplier 1, when the procedure of 'reduce a temperature' is carried out in a bathtub and water is poured, a first opening and closing valve 4 is closed and a flow passage, from the hot-water outlet port side to a hopper 5, is intercepted. On the other hand, a second opening and closing valve 9 is opened whereby cool water is not passed through a heat exchanger 2 for supplying hot-water and water is supplied through a flow passage from the water introducing side of the heat exchanger 2 to the hopper 5. Accordingly, even when hot-water is discharged immediately after carrying out the procedure of 'adding cool water', the starting-up of heat exchanging effect by the heat exchanger 2 for supplying hot-water is quick and a time delay can be restrained since cool water is not poured into the heat exchanger 2 for supplying hot-water whereby the fluctuation of the temperature of supplying hot-water can be restrained.

Inventor: YANG HYANG JA
IPC: H01L27/02
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent a failure beforehand when a high voltage is applied instantaneously to an electrostatic-discharge-protection transistor by joining input/ output pads and first conductive lines together at a plurality of positions. SOLUTION: First conductive lines 206, which are connected to input/output pads 100 at a plurality of positions, are connected to each drain region formed in an active junction 202, respectively, at 90 deg. direction. Even when a high voltage is applied to input/output pads 100 instantaneously in an electrostatic discharge test to flow large currents to the first conductive lines 206, input/output pads 100 disperse the concentrated current to prevent open failure of the conductive lines because input/output pads 100 are connected to a plurality of first lines 206. Consequently, even when an overvoltage is applied instantaneously to an internal circuit by electrostatic charge stored at input/output pads, breakdown of the elements in the internal circuit is minimized.

Abstract: PROBLEM TO BE SOLVED: To effect cladding in the atmosphere without using expensive silver solder by roll-welding while interposing an insert material selected among Al(alloy), Ca(alloy) and Ni(alloy) between a powder sintered material and a produced metallic plate. SOLUTION: The powder sintered material 2 and the produced metallic plate 3 are roll-welded by interposing the insert material 4 of the Al(alloy), Cu(alloy), and Ni(alloy) between both materials. In the case of using the Al(alloy) as the insert material, the warm rolling at 200-500 deg.C and >=5% draft, is executed. In the case of using the Cu(alloy) as the insert material, the warm rolling at 300-600 deg.C and >=5% draft, is executed. In the case of using the Ni(alloy) as the insert material, the warm rolling at 300-700 deg.C and >=5% draft, is executed. In any case, the roll-welding is executed in the atmosphere. In the case of being too low temp. in the rolling, roll-welding is made to insufficient. In the case of being too high temp. in the rolling, the pores in the sintered material 2 are crushed.  In the case of being too large draft, since the pores in the sintered material 2 are crushed, the draft is desirable to be <=30%.
