Title: Infrared-ray detecting piezoelectric vibrator and infrared-ray detecting method
Inventor: OTA HARUYOSHI
IPC: G01J1/02
Filed: 1989-01-18
Abstract: PURPOSE:To perform highly accurate detection by providing a pair of exciting electrodes on the upper and rear surfaces of a piezoelectric vibrating substrate, providing a light absorb ing black body on one surface of the piezoelectric vibrating substrate so as to cover said surface, using ghe black body surface as an infrated-ray receiving surface, and resonating the surfaces at the different resonance frequencies. CONSTITUTION:Exciting electrodes 2 (2a and 2b) forming a pair are provided on the upper and rear surfaces of a quartz resonator substrate 1. A light absorbing black body 3 is provided on the surface of substrate where infrared rays are received so as to cover the surface. When the infrared rays are transmitted through a light transmitting window 4 in a cover 5 and absorbed into the black body surface 3, the temperature of the substrate 1 is increased. As a result, the resonance frequency in a surface sliding vibration attitude is changed. How ever, the resonance frquency in a thickness sliding vibration attitude is not changed very much since the curving point of the resonance frequency is set in the vicinity of normal temperature. The surface sliding vibration attitude has nodes at the center and the centers of the peripheral parts of the substrate 1. Therefore, the substrate 1 is held with holders 6 (6a and 6b) at the central points of the sides of the substrate 1. Thus, both vibrating attitudes can be resonated at the same time without the effect on the vibration in the thickness sliding vibration attitude. The change in resonance frequency of the surface sliding is operated and compared with the resonance frequency of the thickness sliding, and the infrared rays can be detected.

Filed: 1985-01-22
Abstract: PURPOSE:To eliminate ununiform single domain formation, by impressing an electric field in the Z axis direction in a state wherein a load is applied to single crystal of lithium tantalate pulled up in the X-axis direction. CONSTITUTION:The single crystal 1 of lithium tantalate pulled up in the X-axis direction by Czochralski method is kept in such a way that the Z axis is preferably in the horizontal direction, and the electrical insulating weight 2 is placed on the top of the crystal. A pair of the positive and negative electrodes 3 and 3' are attached to the sides of the single crystal 1 in this state. Consequently, load of the weight 2 is applied to the single crystal 1, piezoelectric effect caused by load stress is produced not only on the lower part but also on the upper part, and this piezoelectric effect appears in the same direction as that of the Z axis. Voltage is applied to the electrodes 3 and 3' in the structure. Since piezoelectric effect is generated similarly, difference between the upper and lower part in the crystal, electric field is applied in such a way that the difference between the upper and the lower parts is lessened and made uniform, so that the aimed uniform domain formation can be sufficiently carried out.

Inventor: SUZUKI KUNIAKI
IPC: B41J5/30
Filed: 1990-01-19
Abstract: PURPOSE:To obtain a normal printing result by making printing speed alterable according to the data transfer speed of a host computer. CONSTITUTION:When a CPU 11 detects the empty state of an image memory 14 to issue the request command of image data for a host computer 13, the host computer 13 transmits the image data of one page to a printer. The CPU 11 receives the image data to begin to store the image data in an image memory 14 and performs printing processing through a mechanism control circuit 17 after the completion of the storing of the image data. When the image memory is in an empty state and the storing of the image data is not completed, the CPU 11 discharges paper at that time and outputs a speed indication signal S2 to the mechanism control part 17 so as to decrease printing speed to the speed considered to be in time for the data transmission of the host computer 13 and also requires the re-transmission of the image data of one page presently processed with respect to the host computer 13. By this constitution, the timing of data transfer speed is matched with that of printing speed to obtain a normal printing result.

Abstract: PURPOSE:To improve leakage of a current flowing to the resistance of a trigger circuit by connecting 1st to 3rd resistances in parallel and a transistor in series to a sensor circuit and by driving this transistor by the output of the sensor circuit. CONSTITUTION:To sensor circuit 1, the series circuit composed of resistances 25, 38 and 40 and transistor Tr24 is connected in parallel, and SCR22 is driven by circuit 1 via Tr24. When a detected object of metal, etc., approaches to detection coil 11, oscillation 12 stops and the output of [NC] is ''L'' at a normal time and ''H'' at a detection time. since Tr24 is OFF at the normal time and the threshold level of ZD35 is set smaller than that of constant-voltage diode ZD37, no current flows to resistances 25 and 38 and SCR22 turns OFF. At the detection time, Tr24 is ON and SCR is also ON; and a current is supplied to circuit 1 via resistances 38 and 25 and light emission diode 24 is also supplied with a current. Consequantly, no current flows through resistances 25 and 38 with SCR22 OFF, so that the leakage of a current will improve.

Abstract: PURPOSE:To reliably make an automatic supply of spare sheets without noise by detecting that a transport line is abnormal and there is a missing sheet, then lowering the bottom plate of a magazine storing spare PTP sheets. CONSTITUTION:When an attachment 71 interposed between upper and lower guides 73, 72 for a chain 7 does not transport a sheet S in a space of a lower guide 76 for some reason (a missing sheet) and moves in the direction of an arrow (a), an air cylinder 3 is operated by a missing sheet detecting signal of a photoelectric switch or the like, which causes an operating rod 31 to lower a guide plate 6 and the bottom plate 11 of a magazine 1 coupled thereto for the adjusted amount by an adjusting screw 52. Thereupon, a sheet S on the bottom plate 11 is lowered, which causes the advancing attachment 71 to feed out the sheet S onto a slide guide 77 and the lower guide 76. Thus, an automatic supply of a spare sheet can be accomplished easily, reliably and without noise by only vertical motions of the bottom plate 11 of the magazine 1.
