Title: Cooling device
Inventor: YAMADA KAZUO
IPC: F25B1/00
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To simplify a device structure, to reduce size and weight, and to reduce an occupying floor area by a method wherein a condenser is arranged as a lamination plate condenser, in a cooling device provided with a compressor, the condenser, and an evaporator. SOLUTION: Refrigerant gas compressed by a compressor 1 is heat exchanged with cooling water of a cooling water circuit 8 and converted into refrigerant liquid as the refrigerant gas flows through a refrigerant circuit 7 of a lamination plate condenser 6 by way of a refrigerant piping 5. The refrigerant liquid exchanges heat with brine at a brine circuit and cools brine as the refrigerant liquid flows through the refrigerant circuit of a lamination plate evaporator 9 via an expansion valve, and converted into refrigerant gas which is returned to the compressor 1. In this case, the lamination plate condenser 6 and a lamination plate evaporator 9 are structured such that brazing materials 6b serving as a heat-exchange plate and channel plates 6c of a thin sheet composed of a herringbone type are alternately laminated.  By increasing or decreasing the plates, heat-exchange capacity is increased or decreased and a heat transmission area is optimized. Further, by reducing size and weight, arrangement and piping are facilitated.

Title: Semiconductor memory device
Inventor: NOTSUYAMA YASUYUKI
IPC: G11C17/00
Filed: 1986-03-31
Abstract: PURPOSE:To decrease power consumption by providing a storage means selection transistor (TR) and an output node discharge TR to both ends of a data storage means and by applying conduction control corresponding to a precharge period. CONSTITUTION:At the time of an output node 11 is precharged by a signal phiP,a signal B2 conducts a selection TR 12 and a memory cell MOSFET13 of a series circuit 10. On the other hand, a discharge MOSFET14 is nonconductive by signals the inverse of phiP, A1 and no through-current is generated between power supplies VDD, VSS. At the time of precharge is finished, the TR 14 is conductive and if a depletion TR is used for the TR 13, the TR 13 is conductive, the node 11 is discharged, and if an enhancement TR is used for the TR 13, the TR 13 is nonconductive and the node 11 is not discharged. Thus, only when the precharge is finished and the data are read in the node 11, the TR 14 has only to be subjected to conduction control. Thus, the through- current is decreased to reduce the power consumption.

Title: Facsimile equipment
Inventor: AOKI YUTAKA
IPC: H04N1/00
Filed: 1991-04-03
Abstract: PURPOSE:To optionally select the destination of closed area communication. CONSTITUTION:A numeral ID such as a telephone number included in a control signal transmitted/received before picture information is entered from a numeral ID entry means 1 and it is registered to a numeral ID registration means 2. When the communication line with a destination is connected, a transmission and reception means 3 transmits and receives a control signal at first. Whether or not the numeral ID of the destination included in the control signal is registered is discriminated by an ID discrimination section 4. When the received numeral ID is registered, the picture information inputted/outputted to/from a picture information input means 5. When the received numeral ID is not registered, a DCN signal is transmitted from the transmission and reception means 3. Thus, the connection with the communication line is interrupted. Thus, closed area communication with a destination in a wide range is implemented without transmission reception of a destination not required such as a direct mail.

Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To adequately ensure variable range of a transmission output level, while suppressing the deterioration in the frequency characteristic. SOLUTION: An intermediate frequency variable amplifier 1 amplifies transmission signal at an optional gain and gives the amplified signal to a radio transmission unit 21.
