Title: Current measuring device
Inventor: MIYAKE TOSHIYUKI
IPC: G01R17/06
Filed: 1980-07-31
Abstract: PURPOSE:To eliminate an influence of a change in a resistance value of a load resistance due to a self-heating phenomenon, created by a current, and an ambient temperature, by a method wherein a measurement current and a reference current are alternately applied in a time-division manner to a common load resistance. CONSTITUTION:With switches 10, 7b opened and a switch 7a closed, a measurement current 1 flows to a load resistance 2, and voltages at the opposite ends of the resistor 2 are integrated for a given period of time by means of integrating circuits 4, 5, and 6. Then, with switches 7a, 8b opened and switches 7b, 8a closed, a reference current 9 flows to a load resistance 2 in the reverse direction to that of the measurement current, and voltage, having an inverse polarity, at the opposite ends of the resistor 2 are integrated. A sequence circuit 13 opens a gate circuit 15 for a period until an output of an operational amplifier 4 is brought into a null position. A clock pulse from a pulse generator 14, passing through the gate circuit 15, is counted to measure a measurement current. This prevents the production of a change in an indication value resulting from the exertion of the influence of self- heating, and enables to perform a rapid and stable measurement.

Abstract: PURPOSE:To improve the work efficiency by arranging plural elastic members, which can be elastically deformed in the merchandise passing direction, along this direction in a read area and visualizing the scanning line of reading light. CONSTITUTION:Plural elastic members 31 which can be elastically deformed at least in the merchandise passing direction are arranged along this direction in the lower edge part of a reading window 21, and the scanning line of reading light is projected on elastic members 31 when reading light is scanned from a reading part to the outside through the reading window 21.

After the merchandise passes, the scanning line of reading light is projected again since elastic members are restored to the initial state. Since the operator does not depend on the sixth sense, the reading error is reduced to improve the work efficiency.

IPC: G02B26/00
Filed: 1994-05-20
Abstract: PURPOSE:To stably radiate short-wavelength light formed by converting the light radiated from a semiconductor laser with a high efficiency by disposing a specific optical element between a semiconductor laser and an optical wavelength conversion element. CONSTITUTION:A thin-film optical element 103 is set perpendicularly to the optical axis of the semiconductor laser 101. A part (about <=10%) of the light having a wavelength of, for example, about 870nm of the incident laser beams on the element 103 is fed back to the active layer of the laser 101. The laser beams exclusive of the laser beams reflected by the element 103 pass the element 103. The direction of the laser beams past the element 103 is rotated 90 deg. around the optical axis by a lambda/2 plate 104. The laser beams are condensed at the incident end face of a polarization inversion type waveguide element 106 by a focusing lens 105 after the laser beams pass the lambda/2 plate 104. Thereafter, the laser beam of the wavelength 870nm is converted into a blue light of wavelength 435nm while propagating in the waveguide 108. Consequently, the blue light is stably radiated from the exit end face of the element 106.

IPC: F23N5/12
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a combustion device in which an occurrence of malfunction in control of operation can be reduced. SOLUTION: An input voltage variation monitoring section 36 monitors an amount of variation in which an input voltage Vin supplied to a flame rod electrode 24 is displaced in respect to a predetermined reference voltage Vsp. A data storage section 40 stores a correction data for use in correcting a flame rod current value outputted from the flame rod electrode 24 in response to a varying amount of the input voltage Vin. A sensor output correcting section 38 corrects and outputs the flame rod current value in response to a varying amount of the input voltage Vin monitored by the input voltage variation monitoring section 36 and the correction data of the data storing section 40.  Since it is possible to output the flame rod current value excluding a bad influence of variation of the input voltage Vin, it is possible to avoid a problem that an operation control malfunctions under the flame rod current value set under a bad influence of variation of the input voltage Vin and then it is also possible to reduce occurrence of malfunction in the operation control.
