Title: Frequency converter
Inventor: FUKUDA SACHIROU
IPC: H03D9/06
Filed: 1979-12-26
Abstract: PURPOSE:To stabilize operation against fluctuations of local oscillation electric power, by providing a circuit, composed of a quarter-wavelength line for an intermediate frequency and terminating resistance, between a connection point of a mixer diode and intermediate frequency amplification stage and the ground. CONSTITUTION:A signal inputted from input terminal 4 and local oscillation electric power are mixed by diode 1 and an intermediate frequency signal, after appearing at terminal 5 via microwave stopping filter 2, is amplified by intermediate- frequency preamplifier 3. Between terminal 5 and the ground, a quarter-wavelength line of high characteristic impedance for an intermediate frequency and a terminating resistance with a low resistance value are provided in series. Even if a decrease in local oscillation electric power increases the impedance of the diode, impedance variation viewed from the intermediate frequency amplifier decreases, and consequently the amplifier never gets unstable, so that a little characteristic deterioration occurs in normal operation.

Title: Hot water supplying apparatus
Inventor: KAKIGI TOSHIYUKI
IPC: F24D17/00
Filed: 1983-09-14
Abstract: PURPOSE:To decrease the dissipated heat from a circulating pipeline, by accumulating heat when the temperature in hot water being fed from one end of a heat accumulator is above the predetermined temperature, while by transferring heat from the accumulator to the water when the temperature in hot water is below the predetermined temperature. CONSTITUTION:A plurality of heat accumulators 5, filled with regenerative medium 4 in order to exchange heat with hot water being fed from one end of a pipeline, are provided to a hot water pipeline 2. Water taps 6 to take out hot water, of which heat is to be exchanged by the regenerative medium 4 while the water is passing through the heat accumulators 5, and also provided to the pipeline 2. On the other hand, a pump controlling means 7 stops the operation of a pump 3 when the temperature in the heat accumulator 5 is above the value which is primarily set, and it brings the pump 3 into operation, when the temperature in hot water in the pipeline coming from a storage tank I to the heat accumulator 5 is below the value which is secondarily set. While, the heat accumulator takes surplus heat from the hot water to accumulate, when the temperature in hot water fed from one end of an accumulator is higher than the predetermined temperature, and it transfers the heat accumulated in it to the hot water when the temperature in the water is below the predetermined value. In such a munner, the temperature in hot water can be kept nearly constant when the water is taken out for use.

Title: Dynamic random access memory
Inventor: UEHARA HIDEAKI
IPC: G11C8/06
Filed: 1988-07-07
Abstract: PURPOSE:To reduce power consumption in a standby state by performing the switching of an internal address signal and an external address signal in a refresh operation by a row pre-decoder. CONSTITUTION:The row pre-decoder 70 is constituted of a switching means 71 and a decoder circuit 72, and performs the switching of the external address signals (ADO-ADN) and the internal address signals (AO-AN) in the refresh operation by the switching means 71 of the row pre-decoder 70. Therefore, since it is enough to receive a signal CBR for address switching by the row pre-decoder 70 just before the internal address signals (AO-AN) are inputted, it is not required to operate a NAND gate at the input stage of a CBR control circuit at high speed. In such a way, since the dimension of a MOS transistor comprising the NAND gate can be reduced, the power consumption in the CBR control circuit in the standby state can be reduced.
