Patent JP-S6230921-A (JP)
Title: Optical sensor
Inventor: WATANABE MASANORI
IPC: G01D5/26
Filed: 1985-07-31
Abstract: PURPOSE:To obtain a stable output, by providing a second light-receiving element receiving an output light passing through first and second Fabry-Perot interference devices and by comparing output signals from the first and second light-receiving elements with each other. CONSTITUTION:A light outputted from a light-emitting diode 41 is transmitted through a first Fabry-Perot interference device 42 whose characteristics change according to a physical quantity to be measured, and is then made to branch in two directions by a beam splitter 44, and one split light is transmitted through a second Fabry-Perot interference device 43 and then enters a photodiode 45, while the other enters a photodiode 46 directly. Signals outputted from the diodes 45 and 46 are subjected to a comparing process by a signal processing circuit (not shown in the figure), and thereby the physical quantity to be measured is determined. In this way, the dependency of a quantity of light reaching the diode 46 upon said physical quantity can be made much smaller than the dependency of a quantity of light reaching the diode 45 upon this physical quantity. In other words, a change in the intensity of an emitted light and nonuniformity in a coupling loss can be eliminated by dividing the output of the diode 45 by that of the diode 46.

Title: Voltage peak detector
Inventor: NANBARA TOMOHIKO
IPC: G01R19/04
Filed: 1984-08-16
Abstract: PURPOSE:To decrease the ON resistance of a transistor (TR) and to obtain a voltage peak detector which has a short rising time by connecting plural TRs for switching in parallel or increasing emitter diffusion area. CONSTITUTION:Plural switching TRs 2 are connected to an input signal terminal 11 in parallel and a charging capacitor 3 and a discharging resistance 4 are connected to their emitters in parallel. When a pulse signal is applied to the terminal 1, the TRs 2 turn on to charge the capacitor 3, and the high level potential of the pulse is held, so that a voltage peak is detected. The TRs 2 are connected in parallel, so the ON resistance of the TRs 2 decreases and the rising time is shortened.

Abstract: PURPOSE:To measure a track pitch easily and accurately by bringing a displacement measure into contact with some part of the head fitting member of a tracking mechanism, by displacing the fitting member by one track, and by detecting the displacement. CONSTITUTION:While the top surface of a tracking frame 30a which is the measured surface of a tracking mechanism 30 and the measurer 204d of a magnet scale 204 are not in contact with each other, the tracking mechanism 30 is fitted on a fitting table 220, and a knob 219 is rotated to bring the measurer 204d into contact with the measured surface.

Title: Apparatus for measuring residual chlorine
Inventor: MIYAI JINKICHI
IPC: G01N33/18
Filed: 1986-07-21
Abstract: PURPOSE:To measure residual chlorine simply and accurately without requiring operation, by a method wherein a solution to be inspected is adjusted to pH3-5 by a pH control mechanism and the concn. of hypochlorous acid in the solution to be inspected is measured by an electrode for measuring the concn. of hypochlorous acid. CONSTITUTION:The solution to be inspected flowing through a flow pipe 1 flows in a pH control mechanism 3 to be adjusted to pH3-5 without being substantially diluted. Whereupon, the OCl<-> ion in the solution to be inspected is entirely converted to HOCl. Therefore, by detecting the concn. of HOCl in the solution to be inspected after the adjustment of pH by using an HOCl electrode 4, the total concn. of free available chlorine can be detected. Since the pH of the solution to be inspected is adjusted without substantially diluting said solution, the total concn. of free available chlorine in the solution to be inspected can be directly calculated without requiring operation based on a dilution rate.

Title: Bias sputtering
Inventor: TSUNEOKA MASATOSHI
IPC: H01L21/3205
Filed: 1986-07-23
Abstract: PURPOSE:To obtain a bias sputtering method capable of making the coating property of a film to be formed excellent without causing the decrease of film quality, by forming a bias sputtering film applying a treatment gas having specific gravity larger than argon gas. CONSTITUTION:On the upper part of a chamber 1, a gas supplying port 7 connecting to a treatmint gas source 6 is arranged. For the treatment gas source 6, the following are adopted, krypton gas, xenon gas and radon gas having specific gravity larger than argon gas, or a mixed gas of thease gases and argon gas. The treatment gas is introduced into the chamber 1, whose inside is kept a vacuum of about 1-100 Torr, and electric power is supplied to a lower electrode 3 from a negative power source 5, while an upper electrode 2 is heated by a heater 12. As the result, the surface coating of a silicon wafer W is completed by the effect of plasma generating in the vicinity of the upper electrode 2. As the gas having specified gravity larger than argon gas is used, the acceleration which moves the treatment gas toward the wafer W is decreased. Therefore, the generation of voids can be restrained and the film quality is improved.

Abstract: PURPOSE:To form information pits accurately by reading pit information right after recording and by controlling the peak value of light beam intensity in the recording. CONSTITUTION:The output of a readout level at which information is not written is sampled and threshold level signals stored in capacitors 36 and 39 are compared, so that a comparator 33 converts the pit information into pulses accurately at any time.

Title: Color image processing method
Inventor: MIZUTANI SHIN
IPC: G06T7/60
Filed: 1994-07-25
Abstract: PURPOSE:To correct only a color so that a change in a color of an object is natural without much change in the luminance distribution of the entire image from that of an original image by expressing the color image as a vector in an RGB space in the unit of picture elements and taking only an angle of a normalized image RGB vector into account. CONSTITUTION:A color image is expressed as a vector in an RGB space in the unit of picture element, a norm of the RGB vector of a color original image is calculated and recorded (S11, S12). Then the norm is used to normalize the RGB vectors of all picture elements. The normalized RGB vector of each picture element of the corrected color image is updated so as to decrease its evaluation function (S13, S14). After the convergence of the evaluation function is confirmed, the corrected color image is formed based on the updated normalized RGB vectors of all the picture elements and the RGB vector norm of all the picture elements of the color original image already recorded.
