Abstract: PURPOSE:To always read a picture area accurately by comparing a picture signal obtained through readout of the picture area with a preset value and detecting the relative position in the read area or the size of a picture medium so as to set the read range. CONSTITUTION:A CPU 28 reads a data from a line memory and continues to carry a film in the subscanning direction till the maximum value reaches 25, that is, 0.1 of density or over in a digital value. Succeedingly, the film is stopped at a position advanced by 15mm further from the film tip at that time. The CPU 26 reads the content of a line memory sequentially and compares it with a preset threshold level and memory addresses A, B in crossing with the threshold level are stored. Since the A,B are recognized as the addresses, the film size is obtained by WF=97[mum]X(B-A). The film size in the main scanning direction is discriminated based on the size and the distance till the end of the film is obtained by a horizontal synchronizing signal.

Title: Door lock actuator for vehicle
Inventor: FUKUNAGA KATSUTOSHI
IPC: E05B83/36
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To dispense with a movable connecting pin so as to reduce the number of parts and so as to prevent a defective action by switching a connection lever between a connection position, in which a lock/unlock operation force can be transmitted to an operation lever, and a double lock position, in which this operation force cannot be transmitted, by means of a double lock lever. SOLUTION: A double lock mechanism is constructed of a connection lever 61, which is supported in an operation lever 60 freely oscillationally and removably engaged with an operation lever 65, and a double lock lever 66 interlocking with the connection lever 61. The double lock lever 66 interlocks with a motor 53 serving as a driving source and switches the connection lever 61 between a connection position, in which a lock/unlock operation force can be transmitted from the operation lever 65 to the operation lever 60, and a double lock position, in which transmission of the lock/unlock operation force is prevented because the operation lever 65 hits the air. In this way, a defective action caused when the operation lever 60 is turned so as to be moved from the double lock position to the connection position can be prevented.

IPC: G03G9/08
Filed: 1984-09-03
Abstract: PURPOSE:To obtain toner for developing electrostatic charge images which does not stick to a sheet made of soft PVC and obviates offsetting even when the toner is fixed by a heat roll by incorporating a specific vinyl resin and olefin polymer into the toner. CONSTITUTION:The vinyl resin to be used has the hydroxyl group of 50-350(KOHmg/g). The sticking of the toner to the soft PVC cannot be prevented if the hydroxyl value is <50 and the electrostatic chargeability is poor if said value exceeds 350. The resin to be used is adjusted in the glass transition point to 20-100 deg.C. The caking resistance of the toner is poor if said point is <20 deg.C and the fixability is poor if said point exceeds 100 deg.C. The olefin polymer consisting of PE or PP or a mixture composed thereof is incorpo rated at 0.1-40wt% into the toner. The offset resistance is not enough at <0.1wt% and the fluidity of the toner is poor when the ratio exceeds 40wt%.

SOLUTION: A waste liquid containing nitrogen in an ammonia state in a raw water tank 1 is sent to a reaction tank 2, to which a chlorine-based oxidizing agent is continuously added from an oxidizing agent tank 5 by a pump 16. Acid and alkali are supplied from an acid reservoir 7 and an alkali reservoir 8, respectively, to control the pH of the liquid to 6.5 to 7.5. The waste liquid in the reaction tank 2 is sent by a pump 16 to an inspection tank 4 where the pH and the oxidation reduction potential(ORP) are continuously measured. When the ORP reaches the preliminarily determined value as a function of pH, injection of oxidizing agent is stopped and a reducing agent is injected from a reducing agent reservoir 6. When the ORP decreases to a specified value, injection of the reducing agent is stopped and the liquid is sent to a treating tank 3 by a pump.  The procedures of these processes are recorded in a controlling device to realize an automatic treatment.

Title: Width scanning type rotary head device
Inventor: SOGABE YASUSHI
IPC: G11B5/008
Filed: 1992-07-13
Abstract: PURPOSE:To provide a width scanning type rotary head device capable of satisfactorily and continuously recording/reproducing a signal even at a device having a small angle for a tape winding. CONSTITUTION:Rotary surfaces 8 and 9 rotated by a motor 3 are provided with two rotary heads 10 and 11 attached on positions opposed to each other 180 degrees. The rotary surfaces 8 and 9 are rotated in the width direction of a tape 1 and the signal is recorded/reproduced in almost the width direction of the tape 1 by the rotary heads 10 and 11. Since the attaching position of the rotary head is placed opposing with 180 degrees against the 90 degrees of a tape winding during the scanning of the rotary head 8 on the tape, the recording of the signal is made intermittent. The travelling of the tape 1 is continued and when it reaches the rotary surface 9, the signal is intermittently recorded by the rotary head 11 same as the rotary head 10. A position between the rotary surfaces is set so that the gap of a signal recorded by the rotary head 10 is filled up tracks recorded by the rotary head 11 and thus, the signal is continuously recorded/reproduced on the tape 1.

Abstract: PURPOSE:To form a comparatively long delay time with a simple circuit constitution by comparing a voltage dividing value made by a thermister element and a resistor with the voltage of a reference voltage source and providing an amplifier circuit outputting a signal when both input levels are inverted. CONSTITUTION:When a voltage input is given to an input terminal 4, a voltage dividing value in response to the resistance ratio is impressed to a connecting point between a resistor 8 and a thermister element 7. When the resistance value of the thermister element 7 is decreased by self-heating, the voltage dividing value is decreased accordingly. When a voltage across the thermister element 7 reaches a reference voltage Vr as shown in figure (b) as the result of decrease in the resistance value of the thermister, an amplifier circuit 6 outputs a signal. The leading time (e) of the waveform is a delay time. The delay time is increased more than the time constant comprising a resistor and a capacitor and a value as large as several sec is obtained easily.
