Title: Mark discriminating circuit for mark read machine
Inventor: SUMIDA KAZUYUKI
IPC: G06K7/00
Filed: 1988-04-04
Abstract: PURPOSE:To correctly discriminate marks and to drastically shorten a processing time by deciding the time of a minimum reference voltage as a mark detecting time when the minimum difference between the two reference voltages is >=a prescribed vale. CONSTITUTION:An automatic reference circuit 2 consists of a gain regurator 3 to output a voltage V1 obtained by subtracting a constant voltage VCONST from an input voltage V0 from an input terminal 1, and a filter circuit CR. A subtracting circuit 4 consists of a D/A converter to output a voltage VDA and a substractor 5 to output the voltage obtained by subtracting the voltage VDA from the voltage V0 as a reference voltage VREF. A microcomputer MPU stores the voltage VREF when the output of a comparator COMP is at an H, and when the minimum difference between the voltages VREF which are stored for the columns to be added with the marks is >= the prescribed value, MPU decides the time of the minimum value VREF as the mark detection, and the other time as the dirt detection, etc., and when the said minimum difference is < the prescribed value, MPU decides it as the dirt detection, etc.

Title: Process control system
Inventor: YOTSUMOTO HIROSHI
IPC: G05B5/01
Filed: 1980-06-20
Abstract: PURPOSE:To improve the stability of a valve under high-speed control by discriminating which one of the corrected amount of a valve position found by control arithmetic and that of a present valve position is considered to be the actual output value of the valve, and by generating a signal which corresponds to a shift in valve position. CONSTITUTION:The valve control output signal DELTAP of a control arithmetic part 4 which corrects the deviation epsilon of a process controlled variable 2 from a process 8 from a control target 1 and a difference DELTAP' between a feedback amount PFB from an output station ST6 and the output signal Pn of a valve position arithmetic part 10 are alternated dynamiclly by a selection switch 12. The output DELTAPn of the switch 12 is outputted actually to the ST6 via a process controller 5. For this purpose, the  signal DELTAPn is stored temporarily in a storage device 13; when the last output DELTAPn-1  is greater a prescribed value, the DELTAP is used and when less, the DELTAP' is outputted, thereby correcting errors of the ST6, a process output device, etc. Thus, the stability of a value during high-speed control and quick control is improved and highly  precise control is exercised.

Title: Optical semiconductor element
Inventor: ISHIMURA EITARO
IPC: H01S5/00
Filed: 1986-04-09
Abstract: PURPOSE:To make it possible to control wavelengths and spectra by a reflecting (reflection preventing) film, by making the thickness of the reflecting (reflection preventing) film to be a thickness, at which wavelength dependency of reflectivity is specified. CONSTITUTION:A reflecting (reflection preventing) film having a thickness other than 1/4m wavelength (m=1, 2...) is provided. when a film other than a 1/4-wavelength film is used as a reflection preventing film, the wavelength and the spectrum of emitted light can be controlled. For example, an Si film having a 0. 1 wavelength, an SiO2 film having a 0.4 wavelength and an Si film having a 0.1 wavelength are laminated. Then the width of the half wavelength value of an LED, which is wider than the width of the half wavelength value of a laser diode, can be made narrow effectively. Since the reflecting (reflection preventing) film has the wavelength dependency of reflectivity, the wavelength and the spectrum of the emitted (absorbed) light can be controlled.

Title: Time base correction circuit for magnetic recording and reproducing device
Inventor: HIRATA KENICHI
IPC: G11B20/06
Filed: 1986-04-09
Abstract: PURPOSE:To prevent the disturbance of a reproduced pattern by retarding an input video signal for a prescribed time in response to the result of phase comparison between a reference horizontal synchronizing signal and a horizonotal synchronizing signal including time base fluctuation to be inputted. CONSTITUTION:A phase detection circuit 25 applies phase comparison between the reference horizontal synchronizing signal generated from a horizontal synchronizing signal generating circuit 24 and the horizontal synchronizing signal inputted with time base fluctuation and its phase error is outputted as an error voltage by using a sample holding circuit. The error voltage is fed to a switch circuit 27, and when a switching pulse is at an H level, that is in the steady- state period, the voltage is fed to the votlage controlled oscillator 26 of the next stage. The oscillator 26 oscillates a frequency in response to the output voltage of the switch circuit 27 to change the delay time of the variable delay line 21. The switch circuit 27 is controlled by the switching pulse and after speed search ON, since the level is at L level for a period of DELTAT, the output of the switch circuit 27 goes to the fixed voltage 30 and goes to an H level after a time DELTAT, and becomes an error voltage of the phase detector 25.

Title: Method for processing aluminum group material for ultra-high vacuum
Inventor: ISHIMARU HAJIME
IPC: C23C14/56
Filed: 1983-05-12
Abstract: PURPOSE:To produce a tight aluminum oxide film, by cutting an aluminum group material while it is cooled by an inert gas and oxygen within a dehydrated vessel and forming a plasma on the cut surface. CONSTITUTION:An aluminum group workpiece W is set in a vessel 1 which is dehydrated by a vacuum pump 6 and cut by a cutting tool 4. At the cutting process, the portion to be cut is cooled by an inert gas and oxygen to be supplied from a gas cylinder 9 through a nozzle 8. On the cut surface 18, a plasma 17 is formed by means of a charging electrode 11, and an aluminum oxide film is formed by the plasma. Since such things as cutting oil and impure gas are not present in the vessel, a tight aluminum oxide film can be produced.

Title: Detection method of rain sensor
Inventor: MIZUKAMI YOSHIO
IPC: G01W1/14
Filed: 1989-03-31
Abstract: PURPOSE:To extend the life of an electrode to a large extent by applying DC voltage to a rain sensor in a pulse like manner and judging a rainfall when the output voltage from the rain sensor is a predetermined value or more. CONSTITUTION:When a raindrop is applied to electrodes 2 and the supply of a current is generated between the electrodes 2, pulse like DC voltage V0 is outputted to be compared with a predetermined threshold value and, only when said voltage V0 exceeds said threshold value, a rainfall is judged to output an alarm or control signal. Since the current flowing when it rains is pulse-like and intermittent, a current supply time becomes short as compared with the conventional continuous supply of DC voltage. When the interval of pulses is made large, the current supply time can be markedly shortened as compared with a conventional one and, by delaying the speed of electrolysis, the life of the electrodes can be extended to a large extent.

Abstract: PURPOSE:To efficiently process an original document by not performing the read processing of partitioning materials, indicating boundaries of sets of original document. CONSTITUTION:Partitioning papers 300A-300D which set modes of respective sets of original documents are inserted to bottoms of a set D1 of single-sided original documents a set D2 of single-sided original documents, and two sets D3 and D4 of both sides original documents. A single sheet separating and carrying mechanism is driven by a copy start signal, and the partitioning paper 300A of the set D1 is separated and carried and is fed into a sheet path. When processings of sets D1-D3 are performed successively hereafter to complete ejection of the last original document P1 of the set D3, the partitioning paper 300D is set to a platen. Since this set partitioning paper is not an original document, the copying operation is not performed. Thus, the processing is performed more quickly because unnecessary copying is not performed and the processing speed is increased.

Title: Method of measuring flow rate of fluid
Inventor: DOMINIKU NOWAARU
IPC: G01F1/696
Filed: 1987-04-07
Abstract: The flow rate of a fluid, e.g. hot water, is determined by measuring the temperature of the fluid and the cooling time between two temperature thresholds of a previously heated probe. On the basis of these values, by way of a first interpolation based on a table comprising the cooling times of the probe as a function of different temperatures and flow rates, the cooling times at the temperature measured are calculated for all the flow rates recorded on the table, then, by way of a second interpolation between the values thus calculated which are higher and lower than the value measured, the flow rate corresponding to this value is calculated.
