Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To lower the cost of the whole power unit for the image reader including a high-precision, low-noise power source for a CCD linear image sensor. SOLUTION: The power unit 70 for the image reader consists of a switching regulator power source and an analog power source for a general component for an A/D circuit board 43 and a CDS circuit board 42 uses a DC power source ±Va3(±15V) obtained by stepping down the switching regulator power source by three-terminal regulators 71 and 72.

Title: Image forming device and recording medium selecting and feeding method therefor
Inventor: ITO YOSHINORI
IPC: G03G15/00
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To preferentially select a recording medium which a user intends under a use environment where the use frequency of each recording medium selected is varied by changing a feeding priority order based on the use frequency of each recording medium stored at a storing means. SOLUTION: When the user does not designate paper from an operation panel part, the controller part 14 of a copying device main body decides the kind of the paper supplied to a printer engine 27 in accordance with the priority order of the use frequency per the kind set at the inside of a memory 23. The user changes the normal value of the priority order through the operation panel part. Also, set information is stored even after the copying device main body is turned off. When the user designates an automatic paper selection mode, a controller 24 detects an original read in by a reader part 12 and the size of image data given by an external device, so that the paper matching with the size of a forming image is automatically selected.

Title: Laser device
Inventor: SHIBATA ISAMU
IPC: G05D25/00
Filed: 1981-07-17
Abstract: PURPOSE:To control laser outputs, motor revolutions and the synchronization of beam modulation by detecting the transmitted and reflected rays from the patterns recorded between the respective holograms of a hologram scanner wherein plural holograms are arrayed in the rotating direction. CONSTITUTION:A glass disc 21 is recorded with many holograms 211, 212,...22n at constant intervals on the same circumference, and is recorded with prescribed patterns 231,...23n between the respective holograms.

Title: Paint applying device
Inventor: USUBA YUKIO
IPC: G21C17/10
Filed: 1993-05-13
Abstract: PURPOSE:To hold a paint pushing-out quantity per unit time constant, and form a paint film having a uniform thickness in a small diameter pipe by pushing out a syringe piston by converting constant speed rotation into rectilinear motion. CONSTITUTION:In order to push paint A filled in a syringe 23, a constant speed rotation motor 33 is driven, and a screw bar 37 is rotated at constant speed. Since rotation of a pipe 39 is regulated, rotary motion of the screw bar 37 is converted into rectilinear motion of the pipe 39, and a syringe piston 29 connected to the pipe 39 is pushed out at constant velocity according to the rotary motion of the screw bar 37. Thereby, even if a pushing-out quantity of the syringe piston 29 becomes different due to a quantity of the paint A filled in the syringe 23, a pushing-out quantity of the paint A per unit time becomes constant. Thereby, when a casing 22 containing a nozzle 25 is moved at constant velocity in a spiral shape in the circumferential direction along an inner wall surface, a paint film having a more uniform thickness can be formed on the inner wall surface 6 by the paint A pushed out in a regulated quantity.

Abstract: PURPOSE:To obtain a core structure which has stable magnetic characteristics against a change in the lapse of time and is excellent in yield by making the border between the 1st magnetic film and a block on a medium slide surface not parallel regardless of the variation of the slide surface while the 1st magnetic film is not formed in a groove for winding. CONSTITUTION:A magnetic pole-gap-magnetic pole element function is satisfied by a material 2 with highly saturated magnetic flux density as the 1st magnetic pole, a gap material 7, and a material 8 with highly saturated magnetic flux density as the 2nd magnetic pole which are formed one after another on a substrate 1 with high magnetic permeability. The border between the substrate 1 and material 2 is not parallel to the gap 7 on the head slide surface to suppress the appearance of contour effect. A protection plate has a nonmagnetic material 11 on the slide surface side and the clearance to the 2nd magnetic pole 8, or adhesive layer does not become a dummy gap. Further, the lowermost point of the nonmagnetic material 11 or 13 on the side where the protection plate faces the gap is put as close to the slide surface as possible preferably in terms of characteristic, that is because the magnetic resistance of a magnetic circuit is smaller as the high-magnetic-permeability material 12 of the protection plate is closer to the slide surface.

Title: Semiconductor substrate carrying method
Inventor: MACHIDA AKIRA
IPC: H01L21/677
Filed: 1982-06-30
Abstract: PURPOSE:To accurately control speed and location of wafers in different weights and shapes only with control of levitating pressure by using the gravity as a driving force for transferring wafers. CONSTITUTION:In a wafer transferring path structure, a wafer 2 is levitated by the gas blowing through the pores 1 in the region A. In this case, the pores 1 are inclined in order to give an initial speed and the gas is injected in the direction indicated by the arrow 3. In the area other than the region A of the transferring path, the pores are provided at a right angle and the gas is injected upward. In the region B, gas flow is accelerated by utilizing gravity, the gas flows in the equal speed in the region C, but decelerated in the region D and is stopped in the region E. According to this method, speed and position are depending only on the inclination angle but on flow rate of gas and weight of wafer. Therefore, control can be realized with good reproducibility.
