Title: Semiconductor bidirectional switch
Inventor: MIHARA TERUYOSHI
IPC: H01L27/088
Filed: 1990-07-30
Abstract: PURPOSE:To decrease ON resistance by surrounding transistors with channel cut regions and N<+> drift regions of the same conductivity type as a drift region and thereby separating a pair of MOS transistors composing a semiconductor bidirectional switch from each other. CONSTITUTION:An N/N<+> substrate is anisotropically etched to make grooves 11 at positions in where conductive channel cut regions 8 are to be formed. Conductive channel cut regions 8 are formed in the grooves 11 by deposition and etching back of amorphous silicon or polysilicon doped into N form and a gate oxide film 5 is formed. The polysilicon is deposited and patterned to form gate wirings 6 and boron ions are implanted with the gate wirings 6 used as masks to form channel regions 3. Source regions 4 are formed by selectively implanting phosphorus ions and arsenic ions. Layer insulating films 7 are deposited, contact holes 12 are made, and wirings 9 are formed. Thereby cell density is heightened and ON resistance is decreased through microstructure.

Title: Electric vacuum cleaner
Inventor: ISHINO YASUO
IPC: H02P27/02
Filed: 1981-12-09
Abstract: PURPOSE:To stabilize performance, by charging a capacitor for storing triggering energy through passive elements and manual switch, and reducing the difference in power applied to a motor blower with respect to the fluctuation of a power source frequency. CONSTITUTION:The motor blower 1 is connected to a thyristor 2 in series. When the voltage of a capacitor 7, which is charged through electric shock protecting resistors 4 and 5 and the manual switch 6, reaches a breakover voltage, a trigger diode 3 becomes a conducting state. The charge stored in the capacitor 7 is imparted to a gate of the thyristor 2, and the thyristor 2 is made conductive. In tis constitution, even through a remote control line is grounded by any chance, the grounding current flows through the resistor 4 when the side of a power source 9 is grounded and through the resist 5 when the side of a power source 8 is grounded, respectively. Therefore the grounding current flows through only one resistor. Therefore, the charging time until the voltage of the capacitor reaches the breakover voltage can be made short, and the difference in power applied to the motor blower 1 with respect to the power source frequency can be made small.

Title: Limiter amplifier
Inventor: MORIKAWA HIROYUKI
IPC: H03G11/00
Filed: 1990-07-26
Abstract: PURPOSE:To eliminate the need for a special bias circuit and to minimize the gain reduction by introducing each of two outputs of a 2nd stage differential amplifier to each base of a couple of transistors(TRs) of a 3rd stage differential amplifier respectively as a balanced input. CONSTITUTION:When an emitter voltage of a TR Q14 rises due to offset, a change is caused in two outputs of a 2nd stage differential amplifier (b) and a base voltage of a TR Q6 rises, while the base broadcast of a TR Q7 is decreased. Thus, a base voltage of a TR Q8 of a 3rd stage differential amplifier (c) is decreased, while a base voltage of a TR Q9 is increased and similarly a base voltage of a TR Q12 of a 4th stage differential amplifier (d) is decreased and a base voltage of a TR Q13 rises. As a result, an emitter voltage of the TR Q14 is decreased to suppress the offset. Thus, a special bias circuit is not required and the gain reduction is minimized.

Title: Production of roller
Inventor: OGAWA ISAO
IPC: G03G15/20
Filed: 1990-07-28
Abstract: PURPOSE:To easily produce a roller in which the adhesion of a core bar and a polytetraflouroethylene tube is excellent by heating the core bar by electromagnetic induction heating form the outside of the synthetic resin tube and allowing an insulating pressing roller whose shaft is arranged in parallel with the shaft of the core bar to press-bond to the core bar. CONSTITUTION:The core bar 2 to which primer 4 is applied is inserted into t;he synthetic resin tube 3 and heated by performing the electromagnetic induction heating from the outside of the tube 3, and the insulating pressing roller 7 whose shaft is arranged in parallel with the shaft of the core bar 2 is rotated relatively to the core bar 2 so as to allow the tube 3 to press-bond to the core bar 2. While the pressing roller 7 is moved from one end to the other end in the longitudinal direction of the tube 3, press-bonding is performed. Since the press-bonding is performed while air retained between the core bar 2 and the synthetic resin tube is pressed out, the nonuniformity of roller thickness caused by the adhesion in a state where the air, etc., is sealed is eliminated. Furthermore, the tight adhesion between the core bar 2 and the synthetic resin tube is improved.

Title: Warning device for decrease in air pressure of tire
Inventor: HIDAKA KUNIHIKO
IPC: G01L19/12
Filed: 1981-12-14
Abstract: PURPOSE:To make it possible to run the vehicle even though air pressure leakage occurs in the warning device itself, by inserting a shutoff valve, which is closed when the pressure in the path is decreased to a value lower than the actuating pressure of the warning device, in the path through which the air pressure of the tire is guided to the warning device. CONSTITUTION:When the tire pressure is normal, the tire pressure makes bellows 12 shrink against a spring 15. A valve body 14 is in an open position with respect to a hole 9a. When the air pressure of the tire becomes the value lower than the actuating pressure, the pressure, which is guided to the warning device 6 through the hole 9a, a chamber A, a hole 9b, and a pipe 7, is decreased, and the warning is insured. In the case, the air pressure of the tire leaks due to the trouble of the device 6 itself, the spring 15 elongates the bellows 12 when the air pressure of the tire becomes the value lower than the actuating pressure, the valve body 14 is seacted on the corresponding opening end of hole 9a, i.e. a closed valve position. Therefore, the air pressure of the tire is not decreased any more, and the warning is continuously issued from the device.

In case of the conversion mode, whether an inputted character is a vowel or a hyphone is discriminated and when the inputted character is a vowel or a hyphone, the Romaji-Kana conversion is processed. A Kana corresponding to the Romaji is obtained from a Romaji-Kana conversion table 18. Data on a screen buffer 19 are converted for a terminal or the HOST24, set in an output buffer 22 and the transfer processing is executed.

Abstract: PROBLEM TO BE SOLVED: To provide a notifying device automatically implementing the notifying method according to the natural situation. SOLUTION: When the ambient meteorological information D1 is detected by a sensor group 1, a weather state determination section 2 determines the weather state D2 based on the weather information D1 from the sensor group 1.

A control section 4 compares the weather state D2 from the weather state determination section 2 with the expected weather state data set by the notice set section 3. When they coincide with each other, the control section 4 outputs the notice method data indicated by the expected notice time data in the records to the notice set section 3, and an alarm sound is rung from a loud speaker 53.

Abstract: PURPOSE:To enable a longitudinal and forward injection of combustion flame to be performed under a linear form from a plurality of separated gas injection grooves separated to each other by a method wherein an injection part of an annular gas passage is partitioned by the partition plate to be removably attached. CONSTITUTION:An annular partition body 24 having a plurality of inwardly directed partition walls 25 in an equal-spaced apart relation is removably attached between a cylindrical wall 3a at the leading released end of an inner combustion cylinder 3 and a cylindrical wall 1a at a leading released end of an outer combustion cylinder 1 so as to partition off the gas passage 4 and a plurality of gas injection grooves 26 are formed. Due to this arrangement, the mixture gas to be injected from the gas passage 4 is injected under its separated condition at the injecting part, and a continuous injection of the mixture gas is not made at the entire circumference of the gas passage 4. Therefore, even if a circulating induction is occurred due to the rotation of the vaporization cylinder 8, the combustion flame injected from each of the gas injection grooves 26 is not circulated and a forwardly directed and stable linear blue flame combustion is continued for a long period of time under a silent condition.
