Title: Abnormal pressure preventing device in hot water circuit
Inventor: ITO YASUO
IPC: B60H1/03
Filed: 1984-07-17
Abstract: PURPOSE:To prevent the pressure in a hot water circuit from abnormally rising to aim at avoiding a breakage, etc. in a heat-exchanger, a hot-water pipe line. etc. even if a heater is operated while a valve disposed in the circuit is left to be opened, by disposing a check valve in the valve element of the valve. CONSTITUTION:In the case of that during the off-season or upon failure of a heater cooling water circuit, valves 1A, 1B are closed to divide the cooling system into an engine 3 side second hot water passage 10B and a heater side first hot water 10B, and then a preheating type heater 5 is erroneously operated again while the valves 1A, 1B are left to be closed, the pressure in the hot water circuit 10B rises due to the combustion heat from the preheating type heater 5. However, when the pressure rises and exceeds, for example, 0.5kg/cm<2>, a disk 31 of a check valve 30 disposed in the valve 1B is opened under pressure to transmit the pressure into the engine 3 side second hot water passage 10A. Further, the pressure rises above the valve opening pressure of a radiator cap 2a, the pressure is therefore, discharged to the outside, thereby the pressure of the cooling water system will not rises above the valve opening pressure. Accordingly, a heating apparatus, pipe line component parts may be prevented from being broken due to abnormal pressure.

Title: Ion descaling method of metal material
Inventor: AKIBA TOYONORI
IPC: C21D1/82
Filed: 1978-12-05
Abstract: PURPOSE:To reduce power consumption necessary for descaling by beforehand heating the metal material having been deposited with scale to 550 deg.C or its transformation point temperature in the case of descaling said metal material through glow discharging in a reduced pressure atmosphere by reducing gas. CONSTITUTION:After the inside of a pressure reducing device 1 built therein with anode 2 is evacuated through a vacuum suction pipe 3, hydrogen gas is supplied through a supply pipe 4 and is put in a reduced pressure state of about 10 Torr. Next, the metal material 6 which has been preheated to the temperature of the range from 550 deg.C up to the transformation point temperature of said material in a preheating furnace 9 and has scale on its surfaces is passed through the inside of the pressure reducing furnace 1 while being sealed with support devices 5. At the same time, with the metal material 6 as cathode, glow discharge is caused between the same and anode 2, whereby the deposited scale is reduced and descaled. Since the temperature elevation of the material up to the start of descaling reaction is accomplished in the preheating furnace 9, the glow discharge power necessary for descaling can be less.

Title: Vapor reflow device
Inventor: HOSHINO SUKEYUKI
IPC: B23K1/015
Filed: 1985-07-09
Abstract: PURPOSE:To relieve the thermal impact to electronic parts by utilizing the latent heat of evaporation in an upper stream side conduit or preheating tank to preheat the parts. CONSTITUTION:Conveyors are so disposed that the terminal 27f of the conveyor 27 on the upper stream side and the beginning end 28s of the conveyor 28 on the down stream side are positioned near the tank 11 in the upper stream side conduit 15. The conveyor 28 on the down stream side travels at such a prescribed speed at which a printed circuit board PB stagnates for a prescribed period in satd. vapor V. On the other hand, the speed of the conveyor 27 on the upper stream side is set sizably lower than the prescribed speed. The circuit board PB carried on the upper stream side conveyor 27 is therefore transferred at the low speed in the cooling section of the upper stream side conduit 15 in which the equiv. temp. monotonously rises. The temp. of the circuit board PB and the electronic parts gradually rises and the thermal impact is relieved. The circuit board PB rides onto the down stream side conveyor 28 from the upper stream side conveyor 27 near the tank 11 and is subjected to a reflow treatment in the tank 11. The treated circuit board is ejected through a conduit 16.

Title: Semidouble base band transmission system
Inventor: KAGEYAMA KOICHI
IPC: H04L5/16
Filed: 1992-06-10
Abstract: PURPOSE:To improve reliability by preventing the detection of carrier interruption in a reception side by adding a data signal having prescribed transition behind a transmitted data signal only during a period when a transmission request signal is turned on. CONSTITUTION:In an NRZI system, a transmission side detection part 8 detects the transmission completion of a final code composed of a trailing pad TP, for which 'one bit' added behind an end flag F of a transmitted data signal SD in the case of one packet transmission is composed by two bytes. On the other hand, a reception side carrier detection part 18 does not count the absence of transition by four bytes yet after final transition with a final bit '0' of the end flag F in received data RD is detected. Therefore, a carrier detection signal CD is turned on. On the transmission side, a data addition part 9 adds the data signal PD of prescribed transition behind the signal SD only during a period when a transmission request signal RS is turned on corresponding to the final code detection completion of the detection part 8. Thus, the detection of carrier interruption on the reception side is prevented.

Title: Plasma treatment equipment
Inventor: YOKOYAMA NAOKI
IPC: H01L21/31
Filed: 1977-12-16
Abstract: PURPOSE:To perform plasma treatment by preventing the temperature rise of the sample and controlling the treating speed. CONSTITUTION:In the region of sample 8, quartz tube 2 is surrounded by solenoid coil 11, thereby generating a magnetic field in the vertical direction inside the tube. In this magnetic field, the plasma flow receives narrowing force and converges on substrate 8. Consequently, changing the strength of the magnetic field will make it possible to adjust plasma density with respect to the sample surface. Although high- frequency electrode 6 is about 150 mm away from sample 8, plasma is transported to the sample by the action of coil 11. Thus the sample is kept at a temperature below 100 deg.C and oxidized.

Abstract: PURPOSE:To reduce the operation stop of the circuit by using an internal signal of a leading edge detection circuit so as to input the signal to a reset input terminal of an RS latch circuit so as to prevent the RS latch circuit from being stopped through malfunction of the leading edge detection circuit. CONSTITUTION:The circuit consists of an RS latch circuit 3 latching a 1st input pulse signal 1 whose period is T1 and whose pulse width is t1 inputted to a set terminal S and a leading edge detection circuit 4 using a 2nd input pulse signal 2 to detect the leading edge of the RS latch circuit, outputting an output pulse signal 5 and outputting a reset signal 6 to a reset terminal R of the RS latch circuit. Then the leading edge detection circuit 4 uses its internal signal as the reset signal 6. Thus, even when an output pulse signal of the leading edge detection circuit 4 is an erroneous signal, when the internal signal is normal, the operation of the RS latch circuit 3 is not stopped and the entire circuit is not stopped to keep the operation and the output pulse signal is restored normally to return the entire circuit to the normal operation.
