Title: Sheet cutter
Inventor: OOYANE YUUICHI
IPC: B65H35/06
Filed: 2003-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To develop a sheet cutter wherein paste is hard to adhere to a cutter material and a cut end of a sheet, having excellent sharpness.  <P>SOLUTION: In the so-called guillotine type sheet cutter, a groove is provided on an inside surface facing a counter part cutter of a moving cutter and/or a fixed cutter, in the length direction along a cutting edge. When cutting a sheet with paste, the paste is adhered to the inside surface (the surface facing the counterpart edge) of the moving cutter and the fixed cutter. However, as the moving cutter moves and cut forward, the paste is rubbed off by the groove and collected in the groove, so that the paste hardly adheres to a part except the groove of the cutter material or the cutting cutter of the sheet.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Image forming apparatus
Inventor: FUKUTANI TAKAYUKI
IPC: G03G15/16
Filed: 2003-04-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of optimum control of a conveyance belt depending on print mode in image formation.  <P>SOLUTION: Upon receiving image data, a CPU (central processing unit) 26 transmits a drive start signal to a motor 25. At the same time as the drive of the motor 25, the monitoring of the output of an encoder 19 is started by a speed detection part 22. A speed determination part 23 compares the period of the pulse output of the encoder 19 with a conveyance belt period that is optimum for image formation, and determines whether the present speed of the belt is at a level that printing is possible or not. An image data color distcrimination means 27 verifies whether the image data transmitted is a color image or a monochrome image. In the case of the color image, the image formation is not started until the output of the required speed is confirmed by the speed determination part 23. At the point of time when the output of the required speed is confirmed, an image formation start signal generation part 24 generates an image formation start signal and a series of image formation processes is started. Control may be performed in the same manner according to image quality mode.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Liquid level detection apparatus for vehicle
Inventor: YASUDA ATSUSHI
IPC: G01F23/28
Filed: 2003-04-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a liquid level detection apparatus for vehicles capable of acquiring satisfactory detection accuracy by suppressing the incidence of secondary reflected waves on an ultrasonic sensor.  <P>SOLUTION: A surface 42 of a bracket 4 for emitting ultrasonic waves, a part opposed to a calibrating plate 6, and the calibrating plate 6 are not arranged in parallel but inclined at an angle θ to each other. The angle θ is set in such a way that ultrasonic waves reflected at a reflecting surface 61 of the calibrating plate 6 toward the surface 42 may be reflected at the surface 42 but not be incident onto the reflecting surface 61 of the calibrating plate 6 again. Since the ultrasonic waves reflected at the reflecting surface 61 and incident onto the surface 42 are thereby reflected on the surface 42 but not incident on the calibrating plate 6 again and does not cause secondary reflected waves, it is possible to reliably prevent malfunctions such as reductions in accuracy in detecting a liquid surface due to the error recognition of a reception signal at the reception of the secondary waves as a reception signal of reflected waves from the liquid level in a conventional liquid level detection apparatus for vehicles.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Optical fiber ribbon

IPC: G02B6/44
Filed: 2003-04-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical fiber ribbon 1 suitable to a new fiber separation method capable of breaking a tape coating layer 5 without making a cut to the layer 5, and a new single fiber separation method is made suitable.  <P>SOLUTION: The layer 5 of the optical fiber ribbon 1 is pressed by drawing members 27 and 33 which have an elastic modulus that is greater than the elastic modulus of the constituting members of the layer 5 and is less than the elastic modulus of colored layers 9. Then, the members 27 and 33 are moved with respect to the tape 1 along the ribbon fiber direction so as to draw the layer 5. Due to friction force between the members and the layer 5, sheared stress is generated in the layer 5 and only the layer 5 is broken. Thus, the tape 1 is made suitable for the new single fiber separation method, inadvertent cutting of the optical fiber ribbon and external damage to the colored layers hardly occur during the single fiber separating process of the optical fiber ribbon.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Measuring probe for crystal oscillator
Inventor: IWAHASHI SHIGEO
IPC: G01H13/00
Filed: 2003-04-15
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a sufficient and stable resonance frequency change according to the pressure change even under pressure, and to accurately measure the properties of the fluid even under pressure, such as a line in a chemical plant, or the like.  <P>SOLUTION: A crystal oscillator 31 is mounted on a casing 21 via an O ring 27, and a lid 22 is clamped by a bolt 28 for supporting and fixing the crystal oscillator 31. In the crystal oscillator 31, the peripheral end of an AT-cut crystal oscillator base sheet is chamfered, or set to the same convex shape, and vibration energy is entrapped inside surrounded by an O ring. In the crystal oscillators 31 in these shapes, a main vibration mode is attenuated at the peripheral end since the superposition of small wavy fluctuations disappears in a charge distribution, and becomes a fine sinusoidal curve-like charge distribution. Therefore, even if the peripheral end of the crystal oscillator is pinched with strong force, the vibration characteristics are not greatly affected, thus obtaining a sufficient and stable resonance frequency change according to the pressure change even under pressure.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
