Title: Objective driving device
Inventor: KOUNO TOMOMUNE
IPC: G02B7/28
Filed: 1983-04-14
Abstract: PURPOSE:To control an objective more correctly in both focussing and tracking directions, by installing a parallel plate spring and pivot bearings to an objective driving device and lightening the mass of the driving section against an elastic member. CONSTITUTION:To a sliding member 18, into which a pivot bearing 17 is press- inserted, one end of the parallel plate spring 19 of an elastic supporting member which supports the movement of an objective 9 in the F-direction is fixed. When an electric current is made to flow to an F-movable coil 11, force is produced in the F-direction and the parallel plate spring 19 becomes a supporting member, and then, the objective 9 is moved in the F-direction while its B-surface is kept parallel to the A-surface of a base body 21. Moreover, when an electric current is made to flow to a T-movable coil 12, the objective 9 is moved in the T-direction around the P-point of pivot bearings 15-17. By using the parallel plate spring for the supporting member of F-direction only, the burden to the plate spring is reduced and the mass of a movable section supported by the plate spring is reduced, and therefore, responses at higher frequencies are improved.

Title: Photographic processing method and printer processor
Inventor: YAMAMOTO HIROYASU
IPC: G03D13/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To miniaturize a device by making the path length of developing processing short without lowering the processing capacity. SOLUTION: Exposure processing is performed while changing the carrying direction of photographic paper in the middle, that is, while carrying the photographic paper in the longitudinal direction at the time of exposure processing, thereafter, the direction thereof is changed to perform the developing processing and the carrying direction of the photographic paper is restored to the longitudinal direction again. Therefore, the degree of freedom in design is increased and lavor saving in the arranging space of the device is realized.  Because the photographic paper 102 is cut by every plural frames at the time of developing processing and the developing processing is performed by making the short side direction as the carrying direction, a processing time can be shortened in order to obtain the specified throughput and respective processing tanks such as developing, fixing and washing tanks are miniaturized. As a result, the entire device is miniaturized.

Filed: 1980-05-20
Abstract: PURPOSE:To detect any kinds of faults and to increase a detection speed remarkably by connecting an output pulse with a little shorter time width than the constant clock pulse period of an oscillating circuit and another output pulse with a little bit longer time width in series. CONSTITUTION:When the period of the output pulse of an oscillating circuit 1 is denoted as TC, the output pulse width TS of a monostable multivibrator 5 which can be triggered again is set a little shorter than the period TC by a TDS, and the output pulse with TL of the monostable multivibrator 5 a little longer than the TC by a TDL. The TDS and TDL are set less as much as possible to the extent where while the TS never becomes longer than the TC, the TL never becomes longer than  TC without reference to the error, temperature deformation and secular change of  used circuit components. Then, those pulses are connected in series to operate on  the loss of an output pulse of the oscillating circuit, high-frequency abnormality and  low-frequency abnormality. Consequently, any fault is detected and a detection  speed is increased very much.

Title: Rotation driving mechanism of spider arm
Inventor: UJIIE MAKOTO
IPC: B41F13/02
Filed: 1991-04-01
Abstract: PURPOSE:To prevent a sudden fluctuation of tension added to a traveling paper by detecting the rotating angle of a spider arm, and setting the degree of acceleration/deceleration of the rotating speed of the spider arm to a determined value corresponding to the rotating angle. CONSTITUTION:When a spider arm 5 is rotated by driving a DC motor 14, the rotating angle of a spider arm shaft 3 is detected by a cam positional resolver 26. The speed of the DC motor 14 is gradually increased from the start to 100% speed, at which the drive is conducted. When the spider arm 5 reaches near a new winding paper installing position, the rotating speed of the motor 14 is linearly reduced, and the drive is stopped when it reaches the installing position. The degree of deceleration is freely set. Therefore, a sudden fluctuation of tension added to a traveling paper at the time of rotation start of the spider arm 5 and at the time of control thereof can be suppressed to prevent the breaking and wrinkling, and the stop position precision can be improved.
