IPC: H01L27/04
Filed: 1985-01-08
Abstract: PURPOSE:To relieve threshold voltage from its temperature-dependency by a method wherein the potential of a semiconductor substrate is varied with substrate temperatures. CONSTITUTION:A substrate potential setting circuit 1 is formed on an Si substrate by making P-N junction diodes 3 in 4-stage series in a forward direction, and a resistor 4 in series. This device is used by connecting a terminal 5 to the ground, and a terminal 6 to the negative bias. Substrate voltages are supplied to the FET of a block 2 through an output terminal 7. With such a construction, the substrate potential is controlled with substrate temperatures, and VT variations generated in the variation in substrate temperature are corrected by utilizing substrate bias effect. This method makes the FET2 before temperature compensation temperature-dependent in threshold voltage at approx. dVT/dTapprox.=-1.8mV/ deg.C in a using set temperature range of -30-+70 deg.C, but the width of VT variation under temperature compensation reduced to 20mV by a factor of 1/9 compared with the variation width 180mV of a MOSFET without compensation.

Abstract: PURPOSE:To prevent transmission error caused by a spike pulse due to noise, etc., or a merit error in the transmission line and to correctly reproduce a transmitted dial signal by providing a code decision device on the reception circuit-side to decide on a dial pulse. CONSTITUTION:The code decision device 8 on the reception circuit-side receives the information of detecting the first and the second code strings of a dial signal from code detector circuits 5, 6, and compares it with the preliminarily stored prescribed characteristic of a dial pulse corresponding to a dial pulse from a telephone set. 10pps dial pulses, for instance, are masked for a period of 5+ or -0.5msec i.e. the interval from a point of time when the pulse shifts from zero to one to another when shifting from one to zero so that the pulses can be discriminated from spike pulses due to noise, etc. Also, in case the shifting from zero to one appears lastly, the information of pulse end is outputted form the decision device 8 in order to prevent the erroneous continuation of a speak ing state caused by a line error. As a result, only an accurate dial signal can be selected, hence a dial signal from the opposite station can be reproduced correctly.

Title: Waste heat recovery device
Inventor: KANEKO HIDEKI
IPC: F24H1/00
Filed: 1982-01-07
Abstract: PURPOSE:To enable waste heat recovery to be made effectively on an waste heat  recovery system adapted to recover the heat quantitity of the hot water overflowing  from a bathtub into a hot water storage type hot water supplying equipment by a  construction wherein an overflow pipe provided in the bathtub is connected to an  waste heat recovery means of the hot water supplying equipment. CONSTITUTION:When hot water is supplied into a bathtub 2, a tap 4 is opened to  flow the hot water in a hot water storage type hot water supplying equipment into  the bathtub. At that time, water is supplied through the lower part of a hot water  tank 5, and so the temperature in the lower part becomes lower. If the hot water  level in the bathtub exceeds that of an upper opening 11 of an overflow pipe 8, the  overflowed hot water is supplied through a hot water supply pipe into an waste heat  recovery means 3 having an internal heat exchanger 7 where it is allowed to exchange heat with the low temperature water in the lower part of the hot water storage tank and then guided through a drain pipe 10 into a sewage hole 14. The water which has  been heated by the heat exchanger 7 returns into the hot water storage tank 5 by  natural convection. Further, in case overflow occurs due to added hot water, heat  recovery is made in the same manner. In case of draining of the hot water in the  bathtub, heat recovery can be made by opening a drain valve 15 of the overflow pipe 8.

Title: Washing of material to be washed and drying method
Inventor: UCHINO MASAHIDE
IPC: B08B3/08
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for all washing operation by quickly drying a completely washed material by a method wherein after heating the material to be washed at a temperature higher than that of a washing liquid for execution of washing, the material is washed in contact with the washing liquid. SOLUTION: A material 4 to be washed in a heating tank 1 is heated at a temperature higher than that of a washing liquid 5 by circulating a not air generated from a hot-air generator 3, and a heat quantity necessary for drying is stored. Washing is executed by dipping the heated material 4 into the washing liquid 5 of a washing tank 6. For this washing, the material 4 is brought in contact with the washing liquid 5 only for the time required for washing the material 4, and the time for contact with the washing liquid 5 for storing heat required for drying becomes unnecessitated. When the contact of the washing liquid 5 with the material 4 is released, the material 4 is kept at the same temperature as that of the washing liquid 5 or at a higher temperature than the liquid, thus quickly drying operation becomes possible. A drying tank 7 is formed adjacent to the washing tank 6.  A condensation pipe 8 is arranged in the drying tank 7, and a condensation liquid 13 is returned to the washing tank 6.

Title: Semiconductor integrated circuit
Inventor: IKEGAMI FUMIO
IPC: H01L27/04
Filed: 1990-01-08
Abstract: PURPOSE:To prevent malfunctioning with the preclusion of simultaneous operation of output buffers during a scan test by providing an output buffer containing an AND circuit with one input connected to a scan test mode terminal and the other input connected to an internal circuit. CONSTITUTION:When a scan mode terminal 2f is at a 'L' level, a scan FF contained in an internal circuit block 7a forms a shift register to enter a scan mode. At this point, as terminals 2f, 2g and 2h and near-by output buffers 4a and 4f are fixed at 'L' as the terminal 2f is at the 'L' level. Therefore, even if with a shifting of a data of the scan FF, an output from the internal circuit block 7a to the output buffers 4a-4f is inverted at the same time, no outputs of the output buffers 4a-4f will not be inverted. Hence, no power source and ground noises are generated. Even when a simultaneous action occurs in the output buffer separated from the terminal 2f, a scan in terminal 2g and the terminal 2h, the power source and ground noises as caused by the simultaneous action are attenuated with an aid of the power source/ground terminals 2a, 2b, 2o and 2p.
