Title: Interpolating method in image scan recording
Inventor: NAKAHARA MASANAO
IPC: H04N1/393
Filed: 1988-11-17
Abstract: PURPOSE:To suppress the generation of interference nonuniformity due to interpolation generated at the time of performing the duplication of an original image by changing the interpolating position of data whose amount is decided by a variable power ratio at every one or several scanning lines. CONSTITUTION:Assuming the variable power ratio (m) as m=r+t (r is integer part of (m), t is decimal part of (m)), the integer part (r) is set as interpolation data even at the first position of a picture element in an interpolation table No.1. Next, the sum of the decimal part (t) and the (m) is assumed as A. The integer part of the A is set as the interpolation data at the next position of the picture element. And the sum of the decimal part of the A and the (m) is set as a new A. Such operation is repeated for the number of times equivalent to the number of picture elements comprising one scanning line. Next, No.2-No.4 interpolation tables are generated so that the same sequence of an interpolation data string is not attached on a No.1 interpolation table and among them mutually. When the variable power ratio (m) is set at a variable power setting apparatus 6, a CPU 7 generates four kinds of interpolation tables No.1-No.4, and writes them on a table memory 8.

Title: Take-up type air filter mechanism
Inventor: HORII TSUNEYUKI
IPC: F04D29/00
Filed: 1994-11-02
Abstract: PURPOSE: To increase the effective area of an air filter and an amount of filitered air for elongating a usable time by using a roll-like air filter and gradually taking up the filter. CONSTITUTION: An air filter 1 is taken up by a feed reel 2 under the initial condition. When here an apparatus like a liquid crystal projector 7 is electrified, a pulse generator 5 generates pulses every fixed time during the electrification to drive a stepping motor 4. When the drive motor is rotated, a take-up reel 3 connected to the motor 4 is rotated to take up the air filter 1. Further, while a tensioner 6 urges the filter 1 to make intimate contact with a fan 8, it fixes the tension of the filter 1 to smooth the take-up. Thus, while the liquid crystal projector or the like is electrified, the filter 1 moves in front of the air cooling fan 8 of the apparatus by a fixed distance at a fixed time interval so that air can be always filtered through the new portion of the air filter.

Title: Power failure processing circuit for computer
Inventor: MOBARA MASAAKI
IPC: G06F1/30
Filed: 1986-12-08
Abstract: PURPOSE:To stably maintain the memory contents by saving urgently the important information stored in a computer when a power failure occurs to the computer power supply and at the same time applying a resetting mode to prevent the change of memory contents of a memory part. CONSTITUTION:An urgent interruption circuit 20 is set under a latch state when it receives a power failure detection signal DS from a power failure detecting means 10. The latch information is detected by a 1st time limit circuit 30 and a 1st time limit action is started to secure the time needed for urgent saving of a computer 1. Then the latch information is released by a 1st time limit signal TS1 delivered after the 1st time limit action. The generation of the signal TS1 is also detected by a 2nd time limit circuit 40 and a 2nd time limit action is started. A 2nd time limit signal TS2 is produced only in the 2nd time limit action. A resetting circuit 50 produces a resetting signal RS as long as either one of both signals TS1 and TS2 exists. Thus it is inhibited in a 2nd time limit mode to write information into a memory part 2 or to rewrite the memory contents. In such a way, the memory contents are stably maintained.

Title: Highly stable high voltage circuit
Inventor: KITO KOJI
IPC: H04N13/04
Filed: 1987-11-20
Abstract: PURPOSE:To balance output currents from plural flyback transformers at a high speed by comparing an output voltage of a high output voltage detection circuit and a set reference voltage so as to control the conduction period of a high voltage output transistor in a way that the error between the both is decreased. CONSTITUTION:Since a voltage proportional to a high voltage output current of a flyback transformer 4a is generated in a current sensing resistor 8a and a voltage proportional to a high voltage output current of a flyback transformer 4b is generated in a current sensing resistor 8b, the two voltages are inputted to a summing voltage source control circuit 10 and the summing voltage source 9 is controlled so as to make the two voltage equal to each other. Since the high voltage output circuit being a time constant circuit is not placed in a loop of the output current balance control of the flyback transformer, the effect of fast response speed of control is obtained. Since the constant voltage control and the current balance control are separated to the primary and secondary sides, a sufficient capability is applied to the constant voltage control to realize a highly stable high voltage circuit.

CONSTITUTION:When a control current and a driving current are supplied, to begin with, by a Hall element 54, the direction of the supply current to each multiphase coil 52 is controlled, and a needle 50 shifts to either direction. By this shifting, a detection coil 53 crosses the magnetic flux of a permanent magnet 2, so the voltage of sine wave or in the shape of sine wave having the phase difference of 120 deg. arises in a detection coil 53. Accordingly, a supply current of the phase and current value corresponding to the voltage value of the detection coil 53 provided in that multilayer coil 52 flows to the multilayer coil 52 through a controller. Since this supply current is of sine waves or in the shape of sine waves, the torque ripple to be given to the needle 50 which mounts the multiphase coil 52 is small.
