Title: Temperature control method for roller type thermal fixing device
Inventor: HATORI KAZUYUKI
IPC: H05B3/00
Filed: 1989-12-28
Abstract: PURPOSE:To allow a rapid rise and the rapid and uniform heat transfer to a pressurizing roller side without generating fluctuations by rising of the temp. up to the one set temp. higher than a standby reference temp. after turning on of a power source. CONSTITUTION:A timer X and a clutch 16a operate and the temp. rises near to the end point of the entire energization (180 deg.C) or control target temp. (200 deg.C) when the power source is turned on. The operation of the clutch 16a is released by the end signal of the timer X and the revolution of a roller 1a starts. The timers Y and Z operate and the rotation of the roller 1a is continued while the roller 1a maintains the fixing reference temp. for the prescribed time by the proportional control during this time. The fixing reference temp. is switched to the standby reference temp. by the end signal of the timer Y. Then, the timer 1a starts shifting to the standby temp. and the rotation of the fixing roller 1a stops. The accurate fixing operation is executed in this way without prolonging the warmup time and without generating the temp. fluctuation.

Title: Earth leakage breaker restoring device
Inventor: DOBASHI AKIRA
IPC: H01H83/02
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To automatically restore an earth leakage breaker while detecting the operation of the earth leakage breaker due to a temporary cause such as a lightning surge except for the over-current. SOLUTION: When the over-current flows to a communicating equipment 20 of a load side, the over-current is detected by an over-current detecting unit 60 having a rectifier 61, and a relay 72 of a condition holding unit 70 is held by itself. Since a break contact 72c of the relay 72 is turned off, supply of a power source to a motor 81 of a driving unit 80 is stopped, and even if the earth leakage breaker 10 is operated, a switching lever 61 is not restored. When the earth leakage breaker 10 is operated by the lightning surge, since over-current is not detected by the over-current detecting unit 60, the relay 72 is not operated.  Consequently, a break contact 72c is turned on, and when a break contact 32 of the relay 30 is turned on by the operation of the earth leakage breaker 10, the motor 81 is driven by the current from a NiCd battery 5, and the earth leakage breaker 10 is restored through a restoring lever 84.

Title: Ringing eliminating device
Inventor: ASHIBE MINORU
IPC: H04N5/208
Filed: 1993-11-19
Abstract: PURPOSE:To provide the ringing eliminating device which can eliminate effectively ringing even if a cut-off frequency of an input image signal is unknown. CONSTITUTION:By a frequency characteristic analyzing circuit 1, a frequency characteristic of an input image signal Ei is analyzed and its signal band width BW is measured. A repeat period of ringing roughly coincides with a cut-off frequency of the input image signal, therefore, by adjusting the frequency characteristic of a filter circuit 2 in accordance with the measured band width BW, a ringing component R is extracted. By using the band width BW, a contour signal P for showing a contour part of the input image signal Ei is generated by a contour detecting circuit 3. Since ringing is conspicuous in a peripheral part of a contour, a correction amount CA in the peripheral part of the contour is generated, based on the contour signal P. By its correction amount CA, the ringing component R is corrected, and the correction ringing component CR is eliminated from the input image signal Ei delayed for the purpose of phase matching.
