Title: Arc-extinguishing device
Inventor: KUNIMOTO YOICHI
IPC: H01H75/00
Filed: 1989-07-21
Abstract: PURPOSE:To improve arc-extinguishing performance by providing a first reflux outlet near the contact of a reflux side plate, and also a second reflux outlet on the opening side of a contact shoe opposite to an exhaust part. CONSTITUTION:At the time of an accident, arc is generated between contacts 11, 12, and arc gas flows to an exhaust part 8 side. At that time, a part of the arc gas flows backward from the reflux inlet 10 of a reflux side plate 2 through a reflux passage 9 and returns to the vicinity of the contacts 11, 12 from a first reflux outlet 15 as shown by A, and also it returns to the vicinity of the contact 12 opposite to the exhaust part 8 from a second reflux outlet 16. Therefore, even if a space for the operation of a contact 14 opposite to the exhaust part 8 is increased, the arc gas is easy to flow into the exhaust part 9 as the arc gas entered into the opening side of a contact 13 from the second reflux outlet 16, so that the reflux effect of the arc gas is increased, compared with the conventional example having no second reflux outlet 16, progress of the arc is smoothed, and arc-extinguishing performance is thus improved.

Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To enable the self align structured semiconductor device to be formed by the increase of photoresist steps only by forming a metallic silicide to reach the first polycrystalline silicon in the base lead out electrode part, but not to reach a single crystalline silicon in the emitter lead out electrode part. SOLUTION: A metallic silicide 12 is formed to reach the first polycrystalline 4 in the base lead out electrode part, but not to reach a single crystalline silicon 1 in an emitter lead out part. Besides, the polycrystalline silicon as an underneath layer of a gate electrode of a MISFET is the same as the polycrystalline silicon as another underneath layer of a base lead out electrode of the MISFET. Furthermore, the polycrystalline silicon and a metallic layer as an upper layer of the gate electrode of the MISFET are made the same as the emitter lead out electrode of a bipolar transistor. However, sidewalls for bipolar and MISFET are differentiated. Through these procedures, the semiconductor device can be formed by the addition of the photoresist step only.

IPC: F21S6/00
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a luminaire having a lamp body movable largely and improve operatability in moving the lamp body. SOLUTION: To a support 13, an arm 14 is coupled in such a way as rotatable in the horizontal direction as shown by the arrow around the support 13, and a lamp body 15 having a lamp is coupled with the tip of the arm 14 in such a way as rotatable in the horizontal direction as shown by the arrow C around the arm tip. By this two-step movement, the lamp body 15 is allowed to move largely in the horizontal direction. The operating force to rotate the lamp body 15 relative to the arm 14 is made smaller than the operating force to rotate the arm 14 relative to the support 13. This permits the user to move the lamp body 15 easily as he wishes.

IPC: H03F1/32
Filed: 1985-08-30
Abstract: PURPOSE:To obtain a stable characteristic even at the input of a low level by providing a level detection means detecting an output level (or input level) of a reception circuit and a control means controlling the stop/restart of the feedforward operation of a feedforward circuit. CONSTITUTION:Since the high frequency signal inputted to a mixer circuit 4 has a level sufficiently low because of the attenuation of an attenuator 2, an intermediate frequency signal only exists at the output side of the mixer circuit 4 and no other distortion exists. A part of an output signal of the mixer circuit 3 is extracted and the intermediate frequency signal including the distortion component is attenuated to the same level as that of the intermediate frequency signal at the output side of the mixer circuit 4, the result is added in opposite phase by a differential amplifier 7 via a switching circuit 11 and only the distortion component generated by the mixer circuit 3 is outputted to the output side of the differential amplifier 7. The distortion component is amplified to the same level as the distortion component at the output side of the mixer circuit 3 by the differential amplifier 7, added in opposite phase with the signal at the output side of the mixer circuit 3 by a differential amplifier 8 so as to obtain an intermediate frequency signal at the output terminal 9 in which the distortion component is suppressed completely.

Filed: 1994-08-11
Abstract: PURPOSE:To prevent a Brillouin-scattered beam occurring in an optical fiber from propagating to other fibers and to enhance conversion efficiency in wavelength conversion by inserting an optical isolator between cascade connected optical fibers. CONSTITUTION:A signal beam 1 of conversion origin is combined with a pump beam 2 generated from a pump light source 3 in an optical coupler 4. The combined beam is inputted to the optical fiber 5 to be inputted to the optical fiber 6 after passing through the optical isolator 8. A wavelength--converted beam 7 is generated by a four waves mixing phenomenon in the optical fiber 6. The generated wavelength converted beam 7 is outputted from the output terminal of the optical fiber 6 together with the signal beam 1 and the pump beam 2. In such a manner, by inserting the optical isolator between the optical fiber 5 and the optical fiber 6, the Brillouin-scattered beam 9 occurring in the optical fiber 6 is cut off by the optical isolator 8, and it does not arrive at the optical fiber 5.

Filed: 1987-07-29
Abstract: PURPOSE: To enable stable taking out of a specified concentration of a medium to be treated as distillate by providing a controller to adjust a flow rate of a medium to be heated in an absorber based on temperature in an evaporator. CONSTITUTION: At the start of operation, when steam as medium to be treated begins to be supplied to a heater 15 and a heat supplying device 16 from a rectifying column 1, as temperature in an evaporator 5 is lower than a set temperature, receiving a signal from a sensor S a controller works to fully close a connection path of mixing valves V1 and V2 with the side of a flash tank 35 and a motor of a pump 38 is rotated at a low speed. As a result, water in a device 18 to be heated is heated and rises in temperature by heat as generated when an absorbing solution to be scattered in an absorber 6 absorbs a gaseous refrigerant from the evaporator 5. Then, when the detected temperature of the sensor S slightly exceeds a set temperature of the controller C, the discharge of the pump 38 and the travels of the mixing valves V1 and V2 undergo a PID control to increase the discharge thereof.  This enables the stabilization of the operation of an absorption heat pump 2 to relax temperature hunting of a drain of the medium to be treated flowing out from a heater 15 as well.
