Title: Pinch roll device in down coiler of hot rolling equipment
Inventor: NITANDA MASAO
IPC: B65H20/02
Filed: 1986-11-25
Abstract: PURPOSE:To improve the yield and quality of a product by composing a pinch roll feeding a rolled stock shiftable in the width direction of the rolling material. CONSTITUTION:The position detectors 8, 9 for the width end of a rolled stock S is respectively arranged at the inlet side of a finishing rolling mill 1 and at the inlet side of a pinch roll device 2, and a tip position detector 10 is installed at the outlet side of the pinch roll device 2. An arithmetic and control unit 11 stores the width end position of the rolled stock (s) detected by the detector 8 from the tip position detecting signal of the detector 10 and calculates thereafter the deviation of the width end position of the pinch roll device 2 inlet side with this position as the reference. A motor 13 is then driven with the deviation of the width end position as a command signal and the pinch roll device 2 is shifted in the direction making the deviation zero. Owing to the width end position of the rolled stock (s) being correctly maintained the projection part forming of a coil is eliminated. Consequently, the yield and quality of a product is improved.

Title: Method and system for multiplex transmission
Inventor: OHIRA MASATERU
IPC: H04J3/14
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To surely conduct changeover of a redundancy system of transmission lines. SOLUTION: On the occurrence of a line interruption fault on OC 12 transmission lines from a multiplexer A to a multiplexer F, the multiplexer F detects that a transmission line is interrupted for a reception signal from the OC-12 transmission lines, and transfers automatic protection switching(APS) bytes from the multiplexer A to a multiplexer G. In this case, the APS bytes are inserted to an unspecified area of an OC-192 transmission overhead determined in advance for passing-transfer of the APS bytes. The multiplexer G inserts the received passing-transfer APS bytes to a specified position of the APS bytes on the OC-12 transmission overhead and sends resulting data to the multiplexer D. Thus, a redundancy changeover between the multiplexer A and D is realized in this way.

Title: Minimum value detection circuit for video signal reproducing device
Inventor: ONO AKIHIRO
IPC: H04N5/93
Filed: 1985-12-13
Abstract: PURPOSE:To detect stably and surely a minimum level by setting a detection period at a non-steady-state longer than that at a steady-state so as to include a horizontal synchronizing signal during the detection period even when the disc rotation is unstable such as at rising of a spindle motor. CONSTITUTION:A counter 200 generates the 1st period pulse at each period such as 1H by counting a clock and generates the 2nd period pulse at each period longer than a period corresponding to 1H. The 1st period pulse is selected at a steady-state and the 2nd period pulse is selected at a non-steady-state and they are fed to a register 202 and an average circuit 203. The minimum value appears in the period of synchronizing period normally in the video signal and a minimum value level is detected surely by using the 2nd period pulse because the length of 1H period is fluctuated due to unstable disc rotation at the non-steady-state and the variation in the minimum levels is reduced.

Title: Freezing apparatus
Inventor: OGURA KAZUO
IPC: F25B1/10
Filed: 1993-11-10
Abstract: PURPOSE:To always provide a proper amount of a refrigerant in a freezing apparatus including an intermediate cooling circuit serving to introduce a part of a liquid refrigerant from a liquid reception unit into intermediate compressed gas of a multi-stage compressor by closing the intermediate cooling circuit when a detected pressure value reaches a set value or more upon defrosting operation. CONSTITUTION:When defrosting time is reached, a power supply to a liquid line solenoid valve 7 located on the side of an outlet of an intermediate condenser 6 is interrupted for pump down operation. When an automatic return low pressure switch 21 reaches a set value and is hence opened, power supply to an intermediate condenser solenoid valve 6a is interrupted for interruption of a compressor 1. Further, when a defrosting timer counts a predetermined time, power supply to a three-way solenoid valve 3 is interrupted for switching to a defrosting circuit. Hereby, low pressure is raised to return the low pressure switch 21 and supply power to the intermediate condenser solenoid valve 6a and the compressor 1 for defrosting operation. The solenoid valve 6a is opened until vaporizer pressure exceeds a predetermined value whereby a necessary amount of a refrigerant is supplied from the liquid reception unit 5.

Abstract: PURPOSE:To simplify a lens system and to make an angle of deflection large, and to correct a surface tilt excellently by providing a deformed cylinder surface and a toric surface to a single lens which constitutes a 2nd image formation optical system. CONSTITUTION:The 2nd image formation optical system 6 between the deflecting device 4 of the scanning optical system and a surface 7 to be scanned is composed of the single lens and a convergence point set behind the surface to be scanned with converged light and the surface 7 to be scanned are put in conjugate relation in a main scanning direction. Further, the origin of deflection by a deflecting and reflecting surface and the surface 7 to be scanned are put in conjugate relation in a subscanning direction. Then the single lens is formed of the deformed cylinder surface which differs in subscanning-directional refracting power with the position in the main scanning direction and the toric surface which has different refracting power in the main scanning and subscanning directions. Consequently, the optical system is reduced in size, the angle of deflection can be made large, and the surface tilt is corrected excellently.

Filed: 1991-09-30
Abstract: PURPOSE:To execute ununiform correction with high accuracy by switching and using plural voltage division potential sets having uniform and ununiform potential differences for plural reference potential sets used to be compared with an input analog signal. CONSTITUTION:A parallel A/D converter compares divided voltages Vr1-Vr9 with an analog input signal ASIG by comparators C1-C9 and the result of comparison is given to an encoder 5, in which it s converted into a digital signal. In this case, a signal processing circuit 6 outputs a signal to turn off analog switches AS3-AS1 in the ununiform correction state and to disconnect a voltage divider 3 and reference input terminals VML3-VML1 and then no gamma correction is applied to the analog input signal ASIG and the analog input signal ASIG is subjected to ununiform correction in this state. Moreover, in the reading operation state, the switches AS3-AS1 are turned on, and the signal ASIG is processed while gamma correction is applied to the signal ASIG. Thus, ununiform correction is implemented with high accuracy without gamma correction.
