Title: Information writing/reading device for recording medium
Inventor: UGAWA SHOHACHI
IPC: B41J29/46
Filed: 1989-06-20
Abstract: PURPOSE:To change relative moving speed between a recording medium and an information writing/reading part, and simultaneously, to prevent the jumping phenomenon of an information recording position by changing the relative moving speed by changing some prescribed value into another different prescribed value while keeping a definite correlation. CONSTITUTION:A relative moving speed changing means to change the relative moving speed between the information writing/reading part and the recording medium is constituted of a head carrying shaft 56 the pitches of whose helically cut grooves 56a are different for a front and a back directions. Then, the relative moving speed is changed by this relative moving speed changing means by changing some prescribed value '1' into another different prescribed value '2'. Thus, even if the relative moving speed is changed, the definite correlation is kept, and the jumping phenomenon of the information recording position is never caused.

Title: Optical head device
Inventor: OBA AKITOMO
IPC: G02B7/28
Filed: 1988-06-28
Abstract: PURPOSE:To prevent the wavelength fluctuation of a light source and the influence to be caused by the deformation of a light spot and to decrease the focusing shift by diffracting and separating reflected light generated from a recording medium from an optical axis of an image forming lens by a grating lens, placing a parting of a four-division photodetector in parallel to the diffracted direction, and selecting a distance to the grating lens. CONSTITUTION:A grating lens 25 diffracts and separates a laser reflected light beam of a disk 4 along the track direction 6 from an optical axis of an image forming lens 3. Subsequently, a four-division photodetector 9 is placed between focal lines 10, 11 to which an astigmatism light 5 is orthogonal. Next, by selecting a distance extending from a semiconductor laser 1 to the grating lens 25, a focusing shift generated by the wavelength fluctuation of the semiconductor is minimized. According to such constitution, against the wavelength fluctuation of a light source, a small light spot deformation and the focusing shift are decreased remarkably, and its shift is extremely small and can be reduced to <=0.24mum when the wavelength fluctuation is 10nm.

Title: Method and apparatus for producing print screen
Inventor: TOZAKI HIROMI
IPC: B41N1/24
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce the shift of print pattern significantly by pasting a mesh bonded with a metal to a temporary frame larger than the final finish dimensions, matching a final dimension frame to the meshed part of the temporary frame and then displacing the meshed part other than final dimension frame. SOLUTION: A final frame 1 having final dimensions is applied to the mesh part 2 bonded to a temporary frame internally arranged with a metal 4 having an opening for passing a paste. Coordinate at the opening is then measured and the difference from design dimensions is read out. Shift of the coordinate in the metal 4 is eliminated by displacing the mesh 2 in the direction of the shift thereby applying a tensile force to the metal 4. After the shift of the coordinate is eliminated, the final frame 1 and the mesh part 2 are bonded through an adhesive 3 and then the mesh 2 is cut off along the outer circumference of the final frame 1. Finally, the mesh part 2 within the frame is coated with a photosensitive agent which is eventually hardened to form a filter film thus finishing a print screen.

Abstract: PROBLEM TO BE SOLVED: To reduce the consumption of a battery, by suspending the electric supply from the battery to an optical sensor detecting an abnormal rotary speed during the sliding motion of the door when a latch unit is in a half-latched or a fully latched state. SOLUTION: A sliding door against a car body is provided with a latch unit brought to a fully latched state through a half-latched state by fitting to a striker fixed to the car body, and a motor 8 driving the sliding door by rotating a wire drum connected to the sliding door through a wire. A controller 87 controling the revolution of the motor 8 suspends the electric power from a battery 83 to an optical sensor 84 detecting the rotary speed of the wire drum when the latch unit is in the half-latched or fully latched state. In this way, electric current is not supplied to the optical sensor 84 having a large dark current in the waiting state in the closed condition of the door. Hence, the burden of the battery 83 is reduced even when a car is parked for a long time.

Abstract: PURPOSE: To manufacture a seamless large diameter pipe with small driving power by subjecting a pipe material spirally to a process of bending part of said pipe material in its circumferential and axial directions to outer wide, and gradually expanding the same then bending the same to a straight pipe part.  
     CONSTITUTION: An inner roll 12 is restrained at an angle θ by a pair of guide rollers 41 disposed on both sides of the roll 12, and a pipe material 10 is passed through a clearance 36 at the angle θ with respect to the inner and outer rolls 12, 14 from the left direction. Then, it is driven by the rolls 12, 14 and moves in the direction of the clearance 38 while revolving. The unworked part 10A of the material 10 arriving at the clearance 40 is rolled by the tapered parts 16, 26 of the rolls 12, 14, by which the wall thickness is reduced and the material is bent to the outer side. Thereafter, it is bent to the inner side in the clearance 38 to form a straight pipe part 10C. The above-mentioned process is applied successively and spirally to the material 10, whereby the flow of the material in the circumferential direction is made easy and the need for large driving force is eliminated.
