Abstract: PURPOSE:To obtain the small-sized lightweight core for evaporator having excellent performance by forming a rough surface on the tube inner face by expanding a tube with insertion of a slider into the tube and by performing an electrolytic etching by charging an electrolyte. CONSTITUTION:A slider 16 is inserted into a tube 12, the outer diameter of the tube 12 is expanded by drawing in the arrow mark direction A, the engaging hole of a plate fin 14 and the outer peripheral face of the tube 12 are closely fitted and then the tube curving part 12' is fixed to the lower end of the tube 12 by an adhesion, etc. In the second stage an electrolyte 20 is poured into the tube 12 and an electrode 22 is inserted as well to connect it to the cathode side of DC power source 24 and by connecting the tube 12 to the anode side the electrolytic etching is performed. The rough surface is formed with the formation of numerous small irregularities closely spaced on the inner face of the tube 12. The tube 12 and plate fin 14 are fixed with close fitting by the slider pipe expanding method like this, the production cost is low and the inner peripheral face of the tube 12 is subjected to rough face treatment as well, so the heat transfer efficiency is excellent and the evaporation is performed highly.

Title: Control valve gear
Inventor: OKAZAKI TATSUO
IPC: F16K17/00
Filed: 1981-11-27
Abstract: PURPOSE:To aim at obviating such damage as a twist and so on in a watertight retaining member, by installing two control elements held up in a desired state. CONSTITUTION:When the internal pressure in a control chamber rises, this pressure rising acts on a first control element 61c via a through hole 61g and tends to move this element 61c toward the right. At this time, following the first control element 61c, a second control element 61e tries to move toward the right by force of a spring 61h but hits on a step difference 61i and thereby stops, so that the first control element 61c comes off the second control element 61e. Accordingly, a state of watertightness in the second control element 61e for the first control element 61c is released and the operation liquid flows into a store chamber 41 from a control chamber 35 via the through hole 61g by way of a flow passageway 61d.

Title: Erasing method for magnetic record
Inventor: SOGA TAKASHI
IPC: G11B5/024
Filed: 1986-08-15
Abstract: PURPOSE:To prevent an erasure signal from remaining in the frequency band of a video signal by scanning a magnetic head on a track to be erased and supplying an erasure current which decreases gradually from an initial amplitude level to the magnetic head. CONSTITUTION:While a floppy disk 5 is rotated, the magnetic head 4 is scanned on a track 5a and the erasure current I is supplied to the magnetic head 4. Then, the initial amplitude level of the erasure current I is large, so the track 5a is saturated magnetically with the erasure current I and its video signal is erased, so that the remaining level decreases to nearly the same extent with bulk erasure. Further, the amplitude of the erasure current I decreases gradually, so the residual level of the erasure signal by the erasure current I also decreases gradually. When an attenuation time T is set to >=1sec, the residual level of the erasure signal further drops low enough to disregard.

Title: Control circuit of fm diversity receiver
Inventor: MURAHATA KATSUYUKI
IPC: H04B7/08
Filed: 1984-09-13
Abstract: PURPOSE:To prevent undesired high-cut action, separation control action, etc. by comparing the outputs of a subtractor circuit which subtracts the DC voltage from the S meter output voltage when a control signal is produced and then selecting an antenna. CONSTITUTION:Minus wave detection circuits 7A and 7B produce the DC voltages VA and VB corresponding to the AC components of the S meter output. The level discriminating circuits 8A and 8B produce control signals only when the levels of the VA and VB exceeds the reference voltage levels VRA and VRB respectively. The arithmetic circuit 9A and 9B subtract the VA and VB from the S meter output voltages VSA and VSB when the circuits 8A and 8B produce control signals. A comparison control circuit 10 sends the selection signal to an IF selection circuit 4 for selection of a channel A in the case of VSA-VA> VSB-VB and then a channel B in the case VSA-VA<VSB-VB respectively. At the same time, the circuit 10 sends a signal to an MPX stereo demodulator 6 for execution of a high-cut action and a separation control action. In other words, no control signal is produced unless the DC voltage exceeds the reference voltage.

Filed: 1989-07-26
Abstract: PURPOSE:To improve the debugging efficiency by providing a storage means which successively fetches a signal asynchronous with an executing clock by another clock synchronous with this clock and holds it during the program execution of a first microcomputer. CONSTITUTION:A trace memory SM which samples the signal asynchronous with the fundamental clock of a target slave microcomputer SMCU by the clock synchronous with the fundamental clock is added to an emulator. The address or the like outputted from the target slave microcomputer SMCU is held in the memory SM which traces the asynchronous signal. Consequently, the signal operated asynchronously with the fundamental clock of the target slave microcomputer SMCU having the serial communication function or the like is sampled by the operation clock synchronous with the fundamental clock and is stored in the trace memory SM. The asynchronous signal is traced correspondingly to the state of the program executed by the target slave microcomputer SMCU. Thus, the debugging efficiency is improved.
