Inventor: KASAHARA AKIHIRO
IPC: G11B7/09
Filed: 1990-06-13
Abstract: PURPOSE:To always obtain a stable control characteristic by providing a ring- like position damper in the periphery of a bearing line in axial symmetry centering around the axial center of a sliding bearing mechanism between a movable part containing a movable body and a coil bobbin, and a still part. CONSTITUTION:A ring-like positioning damper member 38 is provided symmetrically even against the surface positioned on a line for connecting the center of an objective lens 28 and an axial center and on the axial center, therefore, when a movable plate 25 is displaced in the focus direction, component in the tracking direction of the damper members 38 opposed by inserting and holding the symmetrical surface can be balanced. Accordingly, a crosstalk in the focus direction and the tracking direction can be reduced, the more stable servo-control in two directions can be realized. Also, by giving the symmetric property by using one ring-like damper member 38, it can be prevented that the crosstalk increases.

Title: Engine cooler for motor cycle
Inventor: HIROSE TATEO
IPC: F02B61/02
Filed: 1978-12-11
Abstract: PURPOSE: To effectively cool the engine for a motor cycle with a simple construction by disposing a lateral radiator with its front side lowered between an engine cylinder head arranged at the lower center of a body and a tank mounted on the upper front portion of the body.  
     CONSTITUTION: When a motor cycle runs, running wind passes through a duct 12 or the like and the recess portion of a tank 3 into a radiator 9. When the running wind passes from the upper surface toward the lower surface over the radiator 9, it cools the collant by heat exchange. This coolant is passed through a pipe 11 to be circulated into a cylinder 10 and a cylinder heat 8 to thereby cool the engine 2. Since the radiator 9 can be contained within the width of the tank 3 without any side projection, no disturbance occurs nor scratches when the motor cycle is fallen down.

IPC: H04N5/372
Filed: 1988-06-21
Abstract: PURPOSE:To suppress the flicker of a fluorescent lamp by obtaining a prescribed reference signal by adding a smear signal generated from a solid-state image pickup device in a horizontal direction by an outputting part. CONSTITUTION:At time t1 in a first field, the impression pulses phiV2, phiV4 of the electrodes G2, G4 of the solid state image pickup device repeat H-level and L-level, and the impression pulses phiV1, phiV3 of the electrodes G1, G3 repeat M-level and L-level, and a smear charge is transferred to a horizontal transferring part 5. At time t2, the impression pulse phiH of the electrode G5 repeats H-level and L-level, and transfers and outputs the smear charge. At that time, since the impression pulse phiR of the electrode G6 stops at L-level, the smear charge is added successively to detection capacity C. At time t4, the pulses phiV1, phiV3 become H-level, and a signal charge is read out, and in the period of time t5, it is outputted successively. In a second field too, the same is repeated. Thus, the reference signal which correlates with information that the signal charge is integrated for one field and bas high precision can be obtained.

Abstract: PURPOSE: To obtain the counter pulse in accordance with the tape travelling position, by supplying the direction detection signal obtained from the double-phase counter clock signal and the clock signal of 4-fold frequency to the 4-notation reversible counter and then counting the clock signals.  
     CONSTITUTION: The direction detection signal SD and clock signal ϕCK are obtained from the counter clock signals ϕ a  and ϕ b  having the repeating frequency according to the extent of tape travelling and through the tape travelling direction detector 2 and the 4-fold clock signal generator 1, and then supplied to the 4-notation reversible counter 4. The counter 4 receives a switch control to the addition and subtraction when the tape is travelling forward and backward respectively. At the same time, the data 0 and 3 are preset to the counter 4 with every edge of the rise and fall of the control signal supplied from the edge selector 3. As a result, the error caused by inversion of the tape travelling directions can be offset, at the same time preventing the occurrence of the unnecessary pulse signal. Then the pseudo counter clock signals ϕA and ϕB showing the tape position in correspondence to the frame cycle of the video signal can be generated 6 based on the counter output signal SCN of the counter 4.

IPC: B41J2/165
Filed: 1989-06-16
Abstract: PURPOSE:To keep ink from remaining at the tip of a blade and eliminate the attached ink quickly from an ink discharge port surface by forming a slit with a specific width, which extends from the tip of a blade to the inside of the blade. CONSTITUTION:On a blade 17, a slit 18 with a prescribed width (0.2mm-2.0mm), which extends from the tip to the inside, is formed.
