Title: Induction heating type iron
Inventor: HIROTA MOTONARI
IPC: D06F79/04
Filed: 1989-06-20
Abstract: PURPOSE:To make unnecessary the on-off control for a steam-sucking fan each time a person irons with steam or irons normally, by a method wherein both the steam- sucking fan and, by the output of a receiving device, a control device controlling the steam-sucking fan are provided, and when the receiving device receives a signal from a transmitting device, the control device operates the steam-sucking fan. CONSTITUTION:Since a receiving signal is a square wave with a period of 1msec, an iron stand-controlling device 31 stops a steam-sucking fan 36 and supplies high frequency power to a heating coil 30. Since an iron body 21 is placed above the heating coil 30, it is heated by induction of the high frequency power supplied to the heating coil 30, and as the result of it, a base temperature of the iron body 21 rises and shortly reaches a preset temperature. At this time, the information about the base temperature from a base temperature-detecting device 22 is that its temperature is equal to the preset temperature or higher. For that reason, an iron body-controlling device 26 turns the signal to a transmitting device 27 into the square wave with the period of 0.5msec. This signal is sent to the side of an iron stand 29 by the transmitting device 27. A receiving device 32 sends the receiving signal to the iron stand-controlling device 31. The iron stand-controlling device 31 stops the excitation of the heating coil 30.

Filed: 1989-06-20
Abstract: PURPOSE:To speed up the operation of a data multiplexer by using a 1st signal (DLP) and a 2nd signal (DLK) which are small in delay quantity. CONSTITUTION:The Johnson counter 20 of a data demultiplexer is equipped with two flip-flops (FF1 and FF2) and a logic gate 21 ORs the Q outputs of the FF1 and FF2 and a clock pulse (CLK). Further, a delay circuit 22 consisting of one gate delays the CLK by a delay time corresponding to the input/output delay time of the logic gate 21 to obtain the DCLK. The output of the logic gate 21 is used as the DLP, so the delay quantity of the DLP is reduced by two stages of gates as compared with a conventional example and the delay quantity of the delay circuit 22 which delays the DCLK is reducible. Consequently, the operation of the data demultiplexer is speeded up.

Title: Production of high molecular piezo-electric conductor
Inventor: DAITOU KOUJI
IPC: H01L41/45
Filed: 1981-10-06
Abstract: PURPOSE:To increase the coupling constant Kt of electric machine providing unstretched film with large thickness piezo-electric characteristics by a method wherein the unstretched film produced by cooling and solidifying the molten copolymer composed of vinylidene fluoride and trifluoroethylene is heat treated after quenching without stretching process. CONSTITUTION:The molten copolymer composed of 70-83mol% of vinylidene fluoride 30-17mol% of trifluoroethylene is quenched at the temperature at least 50 deg.C lower than the crystalline transition temperature Tm'. The refrigerants such as water, liquid nitrogen, liquid air, ammonium and Freon for quenching are actively utilized or the process such as casting said molten copolymer on a refrigerated good thermal conductor is actively adopted. In case of forming said molten copolymer, the melting temperature exceeding the melting point Tm (150-160 deg.C) may be normally acceptable, however, the substantial temperature of 200 deg.C-300 deg.C is preferably adopted considering the effect of temperature dependency on the melting viscocity and the thermal cracking temperature.

Title: Resetting method of receiving equipment
Inventor: SUZUKI EIJI
IPC: H04L27/01
Filed: 1984-07-28
Abstract: PURPOSE:To recover quickly a fault of reception and to improve the circuit using efficiency for a receiving equipment of a digital radio communication, by changing gradually the clock phase when the fault of reception is detected. CONSTITUTION:If the reception distortions are increased by the fading, etc., the equalization, the reproduction of carrier waves and the clock reproduction are not performed in a correct way owing to the reception distortions which exceed the capacity of an equalizer 19. Thus the synchronization is lost with the transmission side, and the base band signals are disturbed. A reception fault detecting circuit 25 decides that the frequency of discordance between the result of discrimination obtained at an original discriminating time point and that obtained at a discriminating time point slightly shifted from said original time point exceeds the prescribed level. Thus the circuit 25 detects a fault of reception and then transmits the sawtooth waves of a low frequency to a variable phase shifter 24 to change gradually the phase of a clock. Thus a state synchronous with the transmission side is obtained periodically. When the reception distortions due to the fading, etc. are decreased, the equalization, the reproduction of carrier waves and the reproduction of clocks are carried out successively in a normal way when the synchronization is secured with the transmission side.

Title: Laser diode
Inventor: GEMA NOBUO
IPC: H01S5/062
Filed: 1979-12-07
Abstract: PURPOSE:To enable production of several laser light rays from a single laser diode and variation of the laser light rays in amplitude by forming the light emitting unit variable in structure. CONSTITUTION:An N region 4 is low density impurity region of impurity density Nd. By representing specific dielectric constant with epsilonr of the region 4, the potential applied externally to the controlled P type region 9 with V, and barrier potential difference when voltage is not applied to the region 9 with Vd, the thickness d of the depletion layer becomes as indicated by the right side formula. In the formula, the region 9 has sufficiently high density as compared with the impurity density of the region 4 to be thus ignored. Thus, a depletion layer having a thickness d is formed toward the region 4 from the region 9. Since the depletion layer having a thickness d proportional to the 1/2 square of the voltage V applied to the region 9 is formed in the region 4 in reverse bias direction externally, when the reverse bias voltage V is gradually increased, a part to which a current flows can be eliminated from the region 4 at certain time.
