Title: Latching-type solenoid device
Inventor: TAKASE YOSHIO
IPC: H01F7/18
Filed: 1990-02-23
Abstract: PURPOSE:To simplify wiring and to make the title device small-sized by a method wherein a drive circuit which drives a latching-type solenoid is united with the solenoid. CONSTITUTION:A pulse generation circuit 2a which drives a solenoid 1 is united with a polarity changeover circuit 2b; a drive circuit 2 is formed. The drive circuit 2 is formed of the following: one pair of switching circuits in which side ends of transistors to which diodes for reverse-current blocking use have been connected are connected to each other; a time-constant circuit, for base bias use, which is formed of a series circuit by a resistance and by a capacitor and which is inserted between a base for the switching circuit on one side and the side end of the diode for the switching circuit on the other side; and a diode for discharge use. When a control switch SW is turned on to the side of (a), an excitation current in the forward direction flows to an excitation coil 10 in the solenoid 1. When the switch is turned on the side of (b), an excitation current in the reverse direction flows to the excitation coil 10. Thereby, an interconnection can be simplified and the title device can be made small- sized.

Inventor: SHIRATO ASAO
IPC: B29L9/00
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To easily and efficiently execute the composite molding between materials different from each other with a general purpose injection molding machine and molds by a method wherein an inner layer material, the softening temperature of which is higher than that of an outer layer material, is filled by injection in a cavity, in which the annular outer layer material has been installed, so as to make the outer layer material and the inner layer material into an integral body. SOLUTION: The following components are employed, for example. The size of the cavity 6 made by molds 1 and 2 has an inner diameter of 9 mm and a length of 65 mm. An outer layer material 7 is a tube having an outer diameter of 8 mm, an inner diameter of 6 mm and a length of 65 mm and made of Teflon (polytetrafluoroethylene). An inner layer material 9 is made of polyimide. The molding temperature is set to be 370 deg.C. The molten resin of the inner layer material 9 is filled in the cavity 6. The outer layer material 7 is softened or semi-melted and stretched by means of the heat and pressure of the inner layer material 9 so as to be pressed against the inner wall of the cavity 6 in order to be integrally shaped together with the inner layer material 9 to the cavity 6.  Further, as for the feeding speed of molten resin, the optimum region is present or a favorable result can be obtained at 8% of the maximum injection speed.

Title: Exhaust pipe of hot water supplying and space heating unit
Inventor: YASUNAGA SHIYUNICHI
IPC: F24H9/02
Filed: 1984-03-07
Abstract: PURPOSE:To contrive to improve the combustion performance and thermal efficiency of the titled unit by a structure wherein a baffle plate equipped with flexible plates is provided within the interior of an exhaust pipe connecting a heat exchanger and an exhaust fan in order for the baffle plate to block the upper part of a heat exchanger, which is put out of use only when either hot water supplying operation or heating operation is put into action independently. CONSTITUTION:When the titled unit is used either for hot water supply only or for heating only, high temperature exhaust gas is produced on the in-use side, because combustion proceeds, and is lead to an exhaust fan. At this time, flexible plates 9 provided on a baffle plate 8 band themselves, because the one end of each plate 9 is fixed, by being heated with high temperature exhaust gas, resulting in opening the slit parts provided on the baffle plate so as to form the passages of the exhaust gas. On the contrary, because the temperature at the out-of-use side (non-combustion side) is low, flexible plates do not bend themselves, resulting in blocking the slit parts 10 provided on the baffle plate. Thus, no air enters from the out-of-use side, resulting in improving the combustion performance and accordingly also enhancing the thermal efficiency.

Title: Driving circuit for impact dot head
Inventor: FUTAGAWA YOSHIKIYO
IPC: B41J2/30
Filed: 1989-02-23
Abstract: PURPOSE:To eliminate an increase in energy consumption due to the heating of a Zener diode and to improve energy converting efficiency and the stability of a current waveform by allowing a driving signal generator to vary the leading edge of a coil current in two stages. CONSTITUTION:In the driving signal generator 10, a current flowing into the coil gradually increases according to the time constant of the coil 3 and that of a driving circuit as the current waveform (i) of the coil 3 shows, when a PNP transistor 5 and an NPN transistor 4 are simultaneously turned on. After first predetermined time t0 has passed, the NPN transistor 4 is turned off. Counter-electromotive force generated in this instance is effectively used as a trailing edge current circulating a coil 5 via the turned on PNP transistor 5 and a diode 7. After second set time t1 has passed, the PNP transistor 5 is turned off, and the counter-electromotive force of the coil 3 is quickly absorbed to a high voltage power line V1 from an unstabilized power source voltage V2 via a counter-electromotive force absorbing diode 8.
