Title: Pressure control valve
Inventor: KOIWAI SHIYUUJI
IPC: F16K17/10
Filed: 1979-07-25
Abstract: PURPOSE: To make a fast response and decrease a peak pressure in a relief valve by a method wherein a piston poppet and a pilot poppet are contacted with each other.  
     CONSTITUTION: When the pressure in a supply port 1 is higher than a predetermined pressure or force of a pilot  spring 14, the pressure is acted upon the spring 14 via the piston poppet 7 and the pilot poppet 13. Then, the poppet 13 is displaced in a leftward direction to release a pressure in a back pressure chamber 11 into a relief port 2, so that the pressure in the back pressure chamber 11 may be decreased. As a result, the relief valve poppet 4 is displaced in a leftward direction to communicate the passage ports 6a, 6b of a check poppet 3 with each other and the pressure at the port 1 is released to the port 2. When the pressure at the port 1 is equal to the desired pressure, the poppet 13 is returned back to abut against a valve seat 13a, thereby a communication between the back pressure chamber 11 and the port 2 is blocked, a pressure in the back pressure chamber 11 is increased by a hydraulic oil from the port 1 and then the poppet 4 is returned back to its original position.

Title: Data recorder
Inventor: TAMAKI ISAO
IPC: A61B5/336
Filed: 1990-04-10
Abstract: PURPOSE:To check recording condition based on a reproduction signal or a signal processed by storing a digital signal at a frequency according to a band width of an analog signal while it is read at a higher frequency to recording it on a tape-like recording medium with a feeding speed thereof corresponding to a ratio of the frequencies intermittently. CONSTITUTION:Analog signals of electrodes 1 and 2 stuck to a human body are converted into digital signals at a timing of a sample pulse of 320Hz with A/D converters 5 and 6 and the digital signals selected with a buffer memory 9 are latched and read by a control signal of 32kHz to perform processings of adding of an error correction code, filtering, interleaving, digital modulation or the like with a signal processing circuit 11. The results are converted into a recording signal to be recorded into magnetic heads 14 and 15 and a magnetic tape T. Only while the digital signals are read, a track TR is formed on the magnetic tape T. A reproduction signal to be reproduced with the magnetic head 15 is corrected with an equalizer 21 based on a frequency characteristic. A signal processing circuit 22 performs processings of decoding, deinterleaving, error detection, error correction, filtering and the like to reproduce the recording signal as digital data.

Title: Heat accumulation type heat exchanger for heating gas containing hydrocarbon and its operation
Inventor: SATO TAKERO
IPC: F28D17/02
Filed: 1990-04-12
Abstract: PURPOSE:To prevent a decomposition of hydrocarbon and generation of soot caused by the decomposition of hydrocarbon by a method wherein a heat accumulation chamber is divided into at least a low temperature side thermal accumulation zone and a high temperature side heat accumulation zone, and at least one mixed cold gas blowing part is disposed at an intermediate part of each of the zones. CONSTITUTION:A checker is divided into two sections for a low temperature heat accumulation chamber 1b and a high temperature heat accumulation chamber 1b. At the high temperature side is generated a decomposition of hydrocarbon. Its temperature is more than 600 deg.C, a spacing is formed at an intermediate part of both chambers, a mixing cold pipe is connected to the intermediate part to form a mixing cold part, thereby a discharging temperature of the high temperature side heat accumulation chamber 1b is prevented from being heated more than an approximate air blowing target temperature in order to adjust the mixing cold amount. In operation, a part near the upper-most part of bricks of the checker shows the highest temperature. A subsequent duct 16 shows a decreased temperature due to a presence of dispersion heat. Actually, adhesion of carbon(soot) is easily produced at the subsequent duct 16 rather than a hole in the bricks of the checker. It is possible to restrict generation of soot and its adhesion at the air blowing duct by making a heat exchanger having such a structure as described above.

Title: Lead frame for plastic seal type semiconductor device
Inventor: YAMANAKA SEISAKU
IPC: H01L23/31
Filed: 1983-05-30
Abstract: PURPOSE:To obtain a lead frame having a function of high-sealing reliability by joining the lead frame and plastics through polyimide layers formed on both surfaces of the inner lead section of the lead frame in a plastic seal type IC. CONSTITUTION:Bond-ability among a sealing resin 12 and lead frames 11 is improved by forming thin layers consisting of polyimide coatings 14 on both surfaces of inner lead sections 13 as sealing sections with plastics 12 of the lead frames 11, and the intrusion of moisture into a package from a joining interface is prevented. The polyimide layers 14 are used in order to enhance bond-ability because polyimide has excellent adhesive properties with epoxy resin as the sealing resin and a Fe-Ni alloy (such as 42 alloy) or a copper alloy employed as the lead frames. Since variance under the state of oxidation of the surfaces of the lead frames due to heating in chip bonding and wire bonding processes is eliminated and the properties of the surface are made constant at all times, a matching with the conditions of sealing is facilitated, and a leakage path is shortened particularly.

Filed: 1979-07-30
Abstract: PURPOSE:To make it possible to exercise a decision on and supervision over the length of a transmitted original at a reception side by counting screen information on the transmitted original on the picture signal unit of one line. CONSTITUTION:Through telephone functions provided to facsimile signal transmitter 1, signal unit 21 and a circuit are set. Then, an original is scanned and a picture signal is sent to unit 21 through the facsimile transmitting functions of unit 1. Unit 21 transfers the received picture signal to memory unit 23, a common unit, and every time a scanning line is detected, the unit informs signal controller 22 of that to count scanning lines by unit 22, thereby informing central controller 25 of the result. Unit 25 calculates the fee for communication from the number of scanning lines of the received picture signal. Then unit 22, when receiving the number of scanning line exceeding a certain reference value determined under the command of unit 25, sends transmission discontinuance command to unit 1 via unit 21. Thus, the fee that corresponds to the length of the original can strictly be calculated.
