Title: Image signal correcting circuit
Inventor: SHIMANAKA MASAYA
IPC: H04N1/407
Filed: 1993-07-16
Abstract: PURPOSE:To enable an appropriate correction even when respective picture element levels are considerably dispersed. CONSTITUTION:A detection part 1 detects the minimum level from image signals P1 for one line of a black reference original and stores it in a register 2. A subtraction part 3 calculates difference between the respective picture element levels of the image signals P1 and the minimum level and outputs a differential value signal H1. A bit processing part 4 performs the bit processing of the signal H1 to prescribed bit width and outputs a differential value signal H2. A code transmission part 9 transmits any specified code concerning the signal H2 for which the prescribed bit width is disabled, and transmits the other signal as a signal H3 to a memory 5 as it is. A bit processing part 6 and an addition part 7 generate a black correct signal H5 by performing bit processing and addition at the minimum level. A subtraction part 8 corrects an image signal P2 in a normal original with the black correct signal and outputs an image signal P3. A code detection part 10 detects the specified code from the differential value signal from the memory and outputs a signal Cd. When the signal Cd is received, an interpolation processing part 11 replaces it with the corrected image signal of a preceding inputted picture element.

Title: Device for regulating opening and closing of air window
Inventor: TAKAADA KENICHI
IPC: B25F5/00
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To reduce the possibility that foreign objects enter an outer frame through an air window, without deteriorating the ability to cool a motor, by providing a cover which closes the air window when a trigger is in its initial position and which, as the trigger is operated, opens the air window by an amount matching the amount by which the trigger is operated. SOLUTION: When a trigger 6 is operated, a fan secured to a motor shaft rotates along with a motor 7, producing cooling wind. Since an arm 4 supporting a cover 1 is secured to the trigger 6, the arm 4 and the cover 1 move in the same direction as the operating direction of the trigger 6. Therefore, when the trigger 6 is operated, i.e., when the motor 7 is driven, the cover 1 closing the hole of an air window 3 moves by the amount of operation of the trigger 6, opening the air window 3 according to the amount of operation. Thus the cooling wind is exhausted out of an outer frame 2. Since the device for regulating the opening and closing of the air window thus opens the air window 3 according to the amount of operation of the trigger 6, the air window 3 opens by an amount matching the amount of power fed to the motor 7, and necessary cooling power can be obtained automatically.

Abstract: PURPOSE:To keep the maximum modulating efficiency, by inserting a pilot pulse to a signal wave and controlling a bias with its detected output to optimize the bias value. CONSTITUTION:A part of an optical output of a modulator is applied with photoelectric conversion at a photodetector 8, amplified at an amplifier 9, inputted to an analog gate 10 and gating is attained by a pilot pulse 6. An output of the gate 10 is held at a hold circuit 11, this is detected synchronizingly at a synchronous detector 12 by a perturbing signal 5, and this output is fed back to a summing amplifier as a feedback signal to the bias. When a bias set value is B+, the phase of the signal 5 and the sample hold output is opposite, the correlation of the both is negative, the bias is moved negatively. When the bias set value is B-, the bias moves positively similarly. When the bias set value is an optimum value B0, the correlation and feedback are zero and the bias value is unchanged. The bias is optimized at all times, even if the optimum bias is fluctuated due to temperature fluctuation.
