Title: Power control circuit
Inventor: TAKAMI HIROYUKI
IPC: H02P7/29
Filed: 1991-02-08
Abstract: PURPOSE:To suppress the power consumption of a motor without supplying power to the circuit part when the load is off and, at the same time, to prevent the malfunction of the motor. CONSTITUTION:A counter 4 is provided for counting the number of turned-on times of a switch SW. The state of the switch SW is switched to each other among states where an oscillation circuit 5 is operated to oscillate, where the output of the circuit section 5 is set at a H level, and where the power supply from a power source circuit section 6 is stopped in accordance with the count value of the counter 4. When the switch 4 is turned on while no power supply is made to a motor M, a trigger pulse is generated from a trigger pulse generation circuit 1 and a transistor TR1 is turned on, resulting in the power supply to each circuit section 3 from a power supply circuit section 10. When the circuit section 10 starts the power supply, a reset circuit section 3 outputs a reset signal for resetting the counter 4. A delay circuit section 5 outputs a delayed pulse by delaying the trigger pulse and the counter 4 counts the delayed pulse after resetting.

IPC: G11B23/00
Filed: 1987-01-30
Abstract: PURPOSE:To reduce a play between a spindle shaft and storage medium by piercing the center hole of a recording medium into which the spindle shaft forming the tip in a tapered shape is inserted in larger diameter than the spindle shaft diameter at its both end opening parts and in the same diameter as the spindle shafts at its center part excepting those and the slope in a lenient shape. CONSTITUTION:The opening parts 8a, 9a of the center holes 8, 9 pierced on absorption plates 6, 7 are formed in a cone-shape and the angle A3 between the surface of the opening parts 8a, 9a and the insertion direction of an optical disk 1 is made smaller than the angle A1 between the tapered face of the tip 3a of a spindle shaft 3 and the insertion direction. The spindle shaft 3 is inserted into the center hole 8 in the state of not colliding with the edge part 8b of the center hole 8 when moving from the opening part 8a to the center hole 8 and the optical disk 1 is placed on a turntable 4. When the spindle shaft 3 is inserted into the center holes 8, 9 of the absorption plates 6, 7, the tip 3a of the spindle shaft 3 is not allowed to collide with the edge parts 8b, 9b of the center hole 8, 9, so the center holes 8, 9 are not reduced. The play between the spindle shaft and storage medium can thus be removed.

Title: Finder optical system
Inventor: HAYAKAWA SHINGO
IPC: G03B13/06
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To easily obtain observation magnification and eye relief having specified length and to observe an excellent finder image by moving a lens on an optical axis, changing the observation magnification and adjusting visibility. SOLUTION: In the case of observing an object image formed on a specified surface by a photographing lens 1, a 1st group L1 having positive refractive power, a 2nd group L2 having negative refractive power and a 3rd group L3 having positive refractive power are arranged in order from the specified surface side. By moving the 1st group L1 on the optical axis from an eye point 8 side to a focusing screen 3 side, variable power is performed. Then, the 2nd group L2 is moved on the optical axis along a locus facing a convex surface on the focusing screen 3 side so as to adjust eyesight. The eyesight adjustment of a finder caused by the difference of an observer is performed by moving the 3rd group L3 on the optical axis.  Thus, the eyesight of the finder is kept nearly constant and an excellent finder image where aberration is excellently corrected is observed though the observation magnification is very largely changed.

Abstract: PURPOSE:To improve the performance by spreading the mixed liquid dipersed with a carbon powder mixed with a metallic powder on the inner face of a cell container to form a film having many convex then contacting it with a positive pole to reduce the contact resistance between the positive pole and the container. CONSTITUTION:The stainless steel powder of 50-100mesh is mixed uniformly in the solution where the carbon powder is dispersed in the water glass, water or an organic solvent then applied on the inner face of a positive terminal/container 2 made of stainless steel to form a current collecting member 3 made of a conductive carbon film having many fine and sharp convex. Then a positive pole 1 is arranged on it while a negative pole 5 made of a separator 4 impregnated with the electrolyte and lithium is further arranged to form a cell. Consequently the contact resistance between the positive pole 1 and the container 2 can be reduced quite easily resulting in the cosiderable improvement of the workability and the discharge performance.

Title: Beltlike body takeup device
Inventor: ITO MASAHIKO
IPC: G03B1/56
Filed: 1987-01-30
Abstract: PURPOSE:To accurately take up a beltlike body by energizing a movable pulley in such a direction that the angle of the winding of a belt around a takeup shaft increases. CONSTITUTION:A film F is guided by the belt 26 from the side of a fixed pulley 21 and taken up by being clamped with the takeup shaft 20. At this time, its angle alpha of winding is secured sufficiently at the start of the winding, so the film is taken up around the takeup shaft 20 without having its tip projected even when no flange is provided to the takeup shaft and no claw is provided to the flange. When the film F is thus taken up successively and its winding diameter increases, the rotary arm rotates right against the force of a spring as shown by an alternate long and two short dashes line and the belt 26 follows up the film F which is large in diameter.

Filed: 1983-02-07
Abstract: PURPOSE:To fix an accurate position of a picture on the paper by controlling both the start of scan and the scan time of an original by the signal sent from a paper sensor set on a feed path for coy paper in case the copying surface of the original has no coincidence with a prescribed size. CONSTITUTION:A start switch is pushed after the copy of a special size is designated from the operation panel of a copying machine, and the feed of the copy paper is started. However a carriage 16 has no shift. Then the copy paper reaches a paper sensor 13 and energizes the sensor 13, and this energization of the sensor is transmitted to a main control part 18 for copying machine and a scan time controller 17. Receiving the signal, the controller 17 calculates the difference between the time needed for transfer of the copy paper sent at a prescribed speed to a transferring position B from the sensor 13 and the time needed for transfer of the surface of a photosensitive body to the position B from an image forming position A. Then the carriage 16 starts the scan of the original on a platen when the time corresponding to said calculated difference is elapped after the copy paper reaches the sensor 13.
