Title: Optical position sensor
Inventor: MATSUI TOORU
IPC: G02B7/32
Filed: 1982-05-04
Abstract: PURPOSE:To perform an accurate range measurement, by constituting an optical position sensor so that both end parts of a slit-shaped reflected optical image span a pair of light shielding layers which are provided to interpose a light-sensitive part on the light receiving face of the optical position sensor. CONSTITUTION:A lens 26 and a light emitting diode 28 constitute a light projecting means 29. The light emitting diode 28 has the light emitting part formed to a stripe shape or a slit shape, and the longitudinal direction of this shape is made vertical to the longitudinal direction of the base line to project the light to an object to be measured. In an optical position sensor 34, for example, p type diffusion regions 38 and 40 are formed on an n type semiconductor substrate 36. A strip-shaped reflected optical image 42 projected to the object to be measured is focused onto the optical position sensor 34, and both end parts of this reflected optical image 42 span light shielding layers 44 and 46. Thus, the quantity of light made incident to the light-sensitive region is not changed even if the reflected optical image 42 is deviated from a center line 48 in the vertical direction.

Title: Absorbance system analyzer
Inventor: TANAKA MASARU
IPC: G01N21/17
Filed: 1981-05-19
Abstract: PURPOSE: To enable high-precise measuring of a low-concentration component and the use of a low-precise device, by regulatig and fixing a device so that signals from two photo detectors are equalized to each other with a given precision.  
     CONSTITUTION: Through flowing of zero gas to a cell 21, a gain control circuit 27 is regulated and fixed so that outputs of photo detectors 23 and 24 are equalized to each other with a given precision. With this, a signal from a differential amplifier 28 is integrated by a signal processing circuit means 29 from a point of time when an integrtor 20 starts to integrate to a point of time an integrated value attains a given value and a coincidence signal is generated, and the value is stored. Sample gas is then flowed to the cell 21, and the signal from the differential amplifier is integrated in a similar manner by the processing means 29 by means of a gain fixed by the control circuit 27. Using the two integrated values, an analysis is then made on a component to be measured. This permits the high-precise analysis of a low-concentration component and enables use of a low-precise device with the signal processing circuit means.

IPC: H05B41/23
Filed: 1989-03-27
Abstract: PURPOSE:To prevent discharge of a discharge lamp inside its outer tube when the discharge lamp is extinguished by connecting a switching element in series with a second capacitance element in an interposing manner, which switching element makes the circuit while the discharge lamp is not lighted and which breaks the circuit in response to lighting of the lamp, and connecting a charge discharge element in parallel with the second capacitance element.
