Title: Double sided flexible disk drive device
Inventor: KUMAKURA TAKESHI
IPC: G11B21/12
Filed: 1989-01-23
Abstract: PURPOSE:To prevent the play caused at a rotary fulcrum part of a lever which turns interlocking with a drive operation mechanism by setting the size of a hole part where an arm part which supports rotatably the lever is inserted in accordance with the size of the arm part and forming the hole part into a constricted part in the width direction of the arm part so as to hold the arm part between both sides of the hole part. CONSTITUTION:A lever 5 turns interlocking with a drive operation mechanism, and an arm part 10 supporting rotatably the lever 5 is put into a hole part 12. The part 12 has a size in accordance with the size of the part 10 and also formed into a constricted part 13 in the width direction of the part 10. Thus the part 10 is held between both sides of the part 12. In such a way, the part 12 is formed into a special shape in order to prevent the play of the lever 5 at its rotary fulcrum part.

IPC: G03B13/02
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To provide the fitting structure of a finder eyepiece part provided with a waterproofing function constituted so that a spectacle protection pad for the finder of a camera is prevented from being turned up and the number of parts required for assembling the finder eyepiece part is reduced. SOLUTION: The spectacle protection pad 10 is provided with a seal member 36 shaped so that window members for a finder 12 and 14 are housed inside and the end part of the window member 12 on a camera body 2 side is enveloped inside from the outside. When the pad 10 is fitted to the camera body 2, the seal member 36 is interposed between the edge 12a of the window member 12 and the camera body 2 and it functions as waterproofing packing. Besides, since the edge of the pad 10 on the camera body side is not exposed outside, the pad 10 is prevented from being turned up because the finger of a user is caught by the edge thereof when the camera is operated.

Title: Ignition circuit for engine
Inventor: HONJIYOU YOSHINAO
IPC: F02P1/08
Filed: 1982-01-28
Abstract: PURPOSE:To enable ignition in an engine from a low speed revolution range to be made and improve the starting characteristic thereof by providing a maximum value detection circuit adapted to detect that the electric current flowing through a primary circuit reaches a maximum value, and an ignition timing compensating circuit. CONSTITUTION:The electric current which short-circuits a primary coil 3 is diverted into a circuit including a transistor (Tr)5 and that including a capacitor 14 thereby charging the capacitor 14. Therefore, the voltage across a resistance 13 becomes the same differential waveform as that of the voltage applied across a linear element 18. Consequently, when the drop in the voltage applied across the whole circuit reaches its maximum value, the voltage becomes zero and control transistors 11 and 20 are turned off. Therefore, a drive transistor Tr7 is turned on and the main transistor 5 is turned off. As a result, the electric current flowing in through the primary coil 3 is cut OFF, a high voltage for ignition generates across a secondary coil 2. On the other hand an  ignition timing compensating circuit is completed through resistances 15, 16 and a Zener  diode 17 so as to render the main transistor Tr5 conductive before the electric current  therethrough reaches its maximum value thereby preventing a delay in ignition timing.

Filed: 1981-02-03
Abstract: PURPOSE:To reuse energy through recovery of the sensible heat from an ingot by disposing jackets enclosing an ingot guide passage between the respective rollers of roller aprons constituting the ingot guide passage and circulating cooling water therein. CONSTITUTION:Molten steel 3 flows through a mold 4, by which a shell is formed. As it passes through roller aprons 7-12 mounted with jacket blocks, the radiation heat generated from the ingot is absorbed by the cooling water flowing in the jacket, whereby the ingot is cooled. The water in a cooling water pit 18 is fed to the respective jacket blocks by means of a cooling water circulation pump 19, and cools the ingot. The resultant hot water is fed to a heat exchanger 24 and the cooling water heat exchanged with a low temp. medium 25 is discharged into the pit 18. The medium 25 is evaporated by the heat exchanging with the hot water past the jacket blocks in the heat exchanger 24 to form a high pressure gas which is fed into a gas turbine 29, thereby driving a generator 30.

Filed: 1979-02-09
Abstract: PURPOSE: To reduce the size of a rectifier circuit by employing two field effect transistors (FET) for a rectifier to enhance the efficiency of a switching regulator.  
     CONSTITUTION: The sources S of two field effect transistors FET9, 10 are commonly connected each other, and an electric current is applied from an AC power supply 11 between the drains D of the transistors. When the transistors 9, 10 are n-channel, the transistor 9 is conducted while the transistor 10 is turned off by the secondary auxiliary winding of a transformer 11 as the polarity of the power supply 1 is connected to the drain D of the transistor 9 and the negative polarity of the power supply 1 is connected to the drain D of the transistor 10. Thus, an electric current is flown to a reactor 4 and a load 7. When the above polarities are inverted, the transistor 9 is turned off while the transistor 10 is conducted, so that the energy of the reactor 4 is flown to the load. When the alternating current is rectified with the transistors 9, 10 to improve the linearity and accordingly the efficiency. Thus, the size of the rectifier circuit is reduced.
