Title: Power converter
Inventor: NAGANUMA KATSUNORI
IPC: H02M7/483
Filed: 1995-05-11
Abstract: PURPOSE: To reduce in size a power converter by reducing the capacity of a filter capacitor in a main converter using an IGBT. CONSTITUTION: When a short-circuit damage occurs in the IGBT 11a of either a two-phase bridge circuit 10 or a three-phase bridge circuit 30, the damage is detected by a current detector 22a, the thyristor 28 of a quick discharging circuit is fired, and a vacuum breaker 2 is operated. Then, a power converter is stopped before a filter capacitor 21b is charged by a shorter quick discharging circuit having a time constant shorter than the discharging circuit without resistor 25. Accordingly, even if the short-circuit damage occurs in the either of the IGBTs and either upper or lower filter capacitor 21a is short-circuited, the other filter capacitor 21b can be so protected as not to be raised to the DC link voltage, and hence the capacitors 21a, 21b can be used in such a manner that they can use a capacitor of low withstand voltage of about 1/2 of the DC link voltage.

Title: Semiconductor switching device
Inventor: YOSHIDA SATORU
IPC: H01L29/74
Filed: 1977-09-21
Abstract: PURPOSE: To obtain a switch of high sensitivity by reducing the junction area face of a thyristor and equivalently inserting a transistor which is not affected by rate effect in parallel therewith thereby letting current be shared.  
     CONSTITUTION: A transistor Q 1  assumes an npn structure with E 1 B 1 C 11  and a thyristor of pnpn is constituted by the E 1 B 1 C 11  of Q 1  and the E 2 B 2 C 2  of Q 2 . A gate breeder resistance RGK is connected depending upon the case. If such constitution is employed, current also flows in the base region of the transisotr at the same instant when the thyristor part is turned ON by the trigger curent from a control electrode 70, whereby switching is effected. On the other hand, when no current flows to the thyristor part, the transisotr part also goes OFF. Hence, the area ratio of the thyristor part may be reduced in consideration for the current amplification factor of the transistor for the current amplification factor of the transistor part also goes OFF. Hence, the area ratio of the thyristor part may be reduced in consideration for the current amplification factor of the transistor and the high sensitivity switching of small influence of rate effect may be produced. Since the area of the thyristor part has become smaller, switching time becomes shorter

Filed: 1977-09-22
Abstract: PURPOSE: To enable to detect simply and accurately hydraulic priming pressure of a hydraulic pump turbine having a hydraulic priming pressure detector by opening a pressure detecting tap at a runner back pressure chamber of the turbine.  
     CONSTITUTION: A pressure outlet tap 4 is opened at the partition wall at the upper cover 9 side of a runner back pressure chamber 8 formed between a runner 1 and the cover 9 in a hydraulic pump turbine and connected through a conduit 5 provided with a control valve 11 at the intermediate thereof directly to a pressure detector 7. When the runner 1 is rotating at the pump starting time to exhaust compressed air for depressing water level, the pressure in the chamber 8 increases while varying in vibration. This pressure increasing rate in the chamber 8 is smaller than that in a runner discharge chamber 3, and the pressure pulsation rate is also smaller than that in the chamber 3. The hydraulic priming pressure can be thus accurately detected simply by the detector 7 even without damper provided at the detector 7 side

Title: Manual original feed type facsimile equipment
Inventor: TANAKA SHINICHI
IPC: H04N1/00
Filed: 1994-05-27
Abstract: PURPOSE:To allow the operator to surely feed drafts continuously by generating a different alarm tone when a time limit of feeding a succeeding original is near so as to raise the attention of the operator. CONSTITUTION:An alarm ringing section 5 has a 1st alarm ring means 5a and a 2nd alarm ring means 5b. When one original is read, the facsimile equipment sends a dummy signal to a receiver side to hold the connecting state of a telephone line and to provide an output of an alarm tone. In this case, a different kind of alarm tone is generated to inform a user of the setting time approaches a time limit. A signal processing section 2 starts a 1st timer circuit 4a in the midst of transmission of the dummy signal so as to generate a 2nd alarm tone to be outputted till the limit time is near from a 1st alarm tone raised in a usual state. Since the alarm tone read by one original is made different depending on the setting time, the interruption of the telephone line due to a delayed feed of the original is prevented, waste of the operating time is avoided and the operability of the facsimile equipment is improved.

Filed: 1985-05-28
Abstract: PURPOSE:To obtain a mist printer which enables to regulate ink droplet diameter and brings about a high quality printing by laminating a film with tiny holes and another film with smaller holes to form an ink film. CONSTITUTION:A serial printer is provided with an ink film 7 which is formed by lamination of a primary film 1 with many tiny holes 1a and a secondary film 2 with smaller holes, and the ink film is wound closely to a heat sensitive head 4. If the heat sensitive head 4 is applied with electricity, the ink in the holes 1 and 2 is suddenly heated to generate bubbles, and the ink flies to adhere to a recording medium 6, resulting in printing. Inasmuch as the ink film 7 moves relatively to the heat sensitive head 4, and moves through an ink supply dives 3, the ink is constantly supplied. As states above, many holes of the film are exposed to a single heat generating body, resulting in a change of ink droplets to become misty, the volume of the ink is controlled to enable a high quality printing.
