IPC: B41J35/36
Filed: 1995-02-03
Abstract: PURPOSE: To realize color printing with high efficiency at a low cost by a constitution wherein plural systems of winding mechanisms each independently winds an ink ribbon of respective plural ink ribbon cartridges corresponding to the respective systems are provided. CONSTITUTION: A power of a stepping motor 30 is transmitted to a gear 37 via a pinion gear 31 and gear 27 in this order, then the gear 37 is rotated in the direction of ribbon winding. As a result, ink ribbons of ink ribbon cartridges 17 in plural systems are simultaneously wound by a ribbon winding mechanism RD. When starting the winding of the ink ribbons, thermal transfer printing by a thermal head 14 is simultaneously started. At the same time, rotation of each gear 37 of the respective system is detected by an encoder 25, then a control section detects the number of revolutions of the gear 37 based on the detection signal. This operation is continuously repeated until completion of the printing, the control section thereby detects the number of revolutions of the gear 37 that rotates until completion of the whole printing.

Title: Method for measuring length of optical fiber by phase change method
Inventor: TAKUMA TAKEYOSHI
IPC: G01B11/02
Filed: 1985-01-31
Abstract: PURPOSE:To measure exactly the length of an optical fiber to be measured by subjecting the light from a light source to sinusoidal modulation by using a synthesizer, making incident the light to the optical fiber, subjecting the exit light from the optical fiber to optoelectric conversion and measuring the phase difference with the electric signal from the synthesizer by a phase meter. CONSTITUTION:The sinusoidal modulation light signal form an electrooptic converter modulated by the sinusoidal wave from the synthesizer 1 is made incident to the optical fiber 3 to be measured. The exit light from the optical fiber 3 is converted to the electric signal by the optoelectric converter 4 and is outputted to the phase meter 5. The sinusoidal modulation light from the synthesizer 1 is inputted by a coaxial cable 6 to the phase meter 5. The phase meter 5 measures the phase difference between the two electric signals. The length of the optical fiber 3 can be exactly determined by investigating preliminarily the phase delays (advances) DELTAthetai, DELTAtheta0 of the converter 2 and the converter 4. The determination of said length is made possible simply by calibrating the phase characteristic with an optical fiber of which the length is exactly known if the investigation of DELTAthetai, DELTAtheta0 is not possible.

Title: Idling engine speed control device
Inventor: FUKUMASU TOSHIHIRO
IPC: F02M69/32
Filed: 1992-01-31
Abstract: PURPOSE:To easily and securely prevent the noise from being generated which comes from the resonance of air vibration in an idling speed control valve(ISCV) to a by-pass passage in an idling engine speed control device provided with the by-pass passage by-passing a throttle valve, and the ISCV for changing the passage area of the by-pass passage. CONSTITUTION:An outlet side by-pass passage 24b reaching an intake passage 21a downstream of a throttle valve 22 from the valve body 28 of an ISCV 23 has a straight pipe part 24d continuous in the same circular sectional form. This straight pipe part 24d is provided with an orifice 40 serving as a member for changing the passage area of the straight pipe part 24d with step difference. Accordingly, the orifice 40 forcibly disturbs the vibrational waveform of vibration caused by air vibration, generated downstream of the valve body 28, as exciting source so as to suppress resonance. Noise can be thereby prevented easily without performing the minute shape adjustment of the outlet side by-pass passage 24b.

Title: Auto-focus device for video camera
Inventor: ITO YUJIRO
IPC: G03B13/36
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To attain the sure JP(just pin) decision against a wobbling action by grasping the transition of evaluation value caused when the focus is moved in the near and far directions from its first position by a prescribed multiple of depth of focus. SOLUTION: When a WOB(wobbling) is carried out in a JP decision state, the evaluation value changes according to the focus state. When a start point (o) is coincident with JP, the change of evaluation value shows a W-shape (A) where the value is reduced twice. This state is decided as JP. When the point (o) is slightly shifted from JP, the evaluation value is also reduced twice or the 1st reduction is unbalanced with the 2nd one (B). This state is also decided as JP. When the point (o) is shifted to a position near the half depth of focus, the evaluation value is reduced and then increased or increased and then reduced. In either case, the difference of reduction is larger than that of increase (C). Under such conditions, the ratio is decided between the difference of reduction and that of increase.  Then JP is decided as long as the difference of reduction is larger than a fixed ratio.
