Title: Tension controller
Inventor: KISHIDA YOUJI
IPC: B65H23/188
Filed: 1983-01-21
Abstract: PURPOSE:To prevent the fluctuation of tension due to a periodical mechanical loss and to give a prescribed actual tension to a work by compensating the periodical torque fluctuation of a driving roll to a torque reference. CONSTITUTION:The position of the driving roll is detected by a position detector 10 consisting of a resolver, a selsyn, or the like, and this position signal is inputted to a mechanical loss storage device 11. A mechanical loss corresponding to the position is outputted periliminarily to the device 11, and the mechanical loss corresponding to the position is outputted by the inputted position signal, and this signal passes a signal adjuster 12 and is given to a current control circuit as a compensating value of the torque reference. By this constitution, even if the periodical mechanical loss exists in the driving roll system, the fluctuation of tension due to the mechanical loss is not given to the work but a prescribed tension is given to it. Consequently, an effective tension control is performed with respect to a line where the feedback control cannot be constituted.

Title: Flash fixing device
Inventor: KENMOCHI SEIICHI
IPC: H05B41/30
Filed: 1984-01-19
Abstract: PURPOSE:To simplify a circuit and improve reliability by detecting whether a flash lamp emits light or not from voltage variation of the capacitor of a rectifying circuit which drives the flash lamp, and retriggering the lamp and allowing the lamp to emit light. CONSTITUTION:An AC voltage 1 is stepped down 2 and rectified 3; and reactors 5 and 6 are connected to the plus side in series and the flash lamp 4 is connected directly to the minus side. A trigger circut 8 is triggered with a trigger signal from a paper feed part which is not shown in a figure to turn on the flash lamp 4. A light nonemission detecting circuit 9 detects the terminal voltage across the capacitor 7 and inputs a retriggering signal to the trigger circuit 8 when detecting nonemission of light, thereby turning on the flash lamp 4. When the lamp 4 is off during retriggering operation, it is judged that the device faults and a trouble signal is generated. Thus, the circuit is simplified and the frequency of trouble is reduced to improve the reliability.

Abstract: PURPOSE:To provide a camera capable of photographing at higher speed in pseudo panoramic size, compared with photographing in full size. CONSTITUTION:The timing for full opening of the front blade 12a and rear blade 12b of a shutter, against the photographic picture frame 11a of the full size and the photographic picture frame 11b of the pseudo panoramic size, is detected by a photointerrupter 42.

Title: Brushless polyphase ac generator
Inventor: HATANAKA TAKESHI
IPC: H02K19/16
Filed: 1986-01-20
Abstract: PURPOSE:To generate an output of bulk capacity in a compact structure by providing to a rotor multiple poles to the positions shifted at a fixed phase angle each axially for motor corresponding to multiple AC output windings. CONSTITUTION:When a rotor 24 rotates clockwise, the flux flows in the opposite direction of an AC output winding 22. Thus, an AC output is obtained as the flux between the first and second static field poles 18 and 19 is interlinked to the AC output winding 22 by the first phase poles 29 and 30 in accordance with the rotation of the rotor 24. Similarly, the second phase poles 40 and 42 interlinks an alternating pole periodically to the second phase AC output winding 23 between the first and second static field poles 19 and 20 in accordance with the rotation of the rotor 24, so that the AC current flows from the output of the first phase AC output winding 22 to the second phase AC output winding 23 at an angle of 120 deg. out of phase. Thus, the three-phase AC output is obtained as the output of a generator.

Filed: 1980-01-25
Abstract: PURPOSE:To expand the scope of the indicating condition of a fluorescent indicator tube, by forming a same phosphor pattern layer astride both an anode segment and an isolating layer surrounding the anode segment. CONSTITUTION:A wiring layer 2, a conductor through-hole 3, an isolating layer 4 and an anode segment layer 5 are formed on an isolating base 1, and a phosphor layer 6 on them is formed so that a same phosphor pattern can include a part 6a spread over the anode segment layer 5 and a part 6b spread over the isolating layer 4. Accordingly, the part 6b becomes low bright compared with the part 6a, and, moreover, the brightness lowers in proportion to the distance from the anode segment 5. As it is thus possible to distribute the brightness on a same indicating pattern, various indicating conditions can be obtained, by means of the phosphor layer 6 covering all over the plural number of anode segment layers 5a-5b, and impressed voltages combined with them.

Abstract: PURPOSE:To well perform an original detection without generating a secondary trouble in a system to perform the original detection by the density difference between an original surface and a background. CONSTITUTION:The original holding surface of the platen cover of an IIT 4 becomes gray in the prescribed density. Thus, even while the platen cover cannot be completely closed, the original can be detected in the completely same manner as the closed condition.

Abstract: PURPOSE:To reduce a laser light loss at Q switching time by providing a full- reflecting member in an optical path of a laser resonator, and displacing an opposing member provided at the reflecting mirror by an actuator when the beam reflected from the member is incident to the full-reflecting mirror. CONSTITUTION:A laser rod 1 made of an erbium-containing glass is excited by a discharge tube 2, a part of a giant pulse emitted from it is reflected on an output mirror 3, and returned to the load 1. Then, the beam emitted from here is incident through an optical path 101 to be incident to a full-reflecting member 5 and also to an opposed member 6, and the beam reflected on the member 5 is incident through an optical path 102 to a full-reflecting mirror 4 to form a Q switch. In this construction, the member 6 is inclined at 45 deg. with respect to the member 5, and the opposing gap (d) between the members 6 and 5 is varied by an actuator 7 provided on the lower end of the member 6. Thus, when the members 6, 5 are made to approach with each other, the beam is leaked externally through an optical path 103, and is incident to the mirror 4 only when they are separated.
