IPC: H04N19/14
Filed: 1991-10-22
Abstract: PURPOSE:To calculate a normalized coefficient of an orthogonal transformation coefficient required for picture signal compression with simple configuration in a short time. CONSTITUTION:A classification section 35 calculates a square mean of AC components for each block with respect to an orthogonal transformation coefficient K1 of a picture signal subject to orthogonal transformation for each block and divides the square mean depending on its magnitude into four classes. Classification mean value calculation sections 31-34 calculate respectively the square mean value of the AC component by the class. A selection section 25 selects square mean values K31-K34 depending on a selection signal S1 and sends an optimum square mean value K5. A normalized factor arithmetic operation section 12 uses a function f(x) so as to operate the optimum square mean value K5 to obtain a normalized factor K6. An exponent arithmetic section 13 receives each quantization bit number Kb of the orthogonal transformation coefficient and the normalized factor K6, multiplies an index in response to the quantized bit umber with the normalized factor to operate and output a normalized coefficient Kn.

Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which prevents unnecessary deterioration of the members of image forming parts, is maintainable high rotation accuracies, and restrains an increase in manufacturing cost. SOLUTION: A photoreceptor 1 for forming a monochrome (black) image is driven by a first drive mechanism 10 composed of a motor 5, the pulley 11 of its drive shaft and the pulley 12 of the photoreceptor 1, and a belt 13 stretched between the pulleys 11 and 12. Photoreceptors 2, 3, and 4 are driven by a second drive mechanism 20 composed of a motor 6 and a belt 18 stretched between the pulley 14 of it and the pulleys 15, 16, and 17 of the photoreceptors 2, 3, and 4, respectively. The monochrome image is formed by the photoreceptor 1 and a developing unit 31, and a color image is formed by all of the photoreceptors and developing units. During the formation of the monochrome image, the image forming parts which are not involved in it are not driven, thereby preventing deterioration and exhaustion of the photoreceptors and developing units.  Also, loads on the motors are not changed even by switching between the color image and monochrome image, and the rotation accuracies are highly maintained.

Title: Control circuit for burner
Inventor: MORITO KATSUMI
IPC: F23N5/20
Filed: 1986-11-18
Abstract: PURPOSE:To reduce unburnt gas in a burner, by a method wherein the feed rate of kerosene, supplied by an electromagnetic pump, is reduced than the one during weak combustion and a combustion flame is brought into close contact with the burner to heat the burner to a high temperature when a control circuit receives a fire extinguishing signal, then, the control circuit stops the operation of the electromagnetic pump when a predetermined time has elapsed. CONSTITUTION:When a fire extinguishing signal is inputted into a relay control circuit 24, the input voltage of a V-F converting circuit 45 becomes low and an electromagnetic pump 12 supplies kerosene, whose amount is far smaller than the same upon weak combustion. Accordingly, only the supplying amount of fuel is reduced than a normal combustion range to make air excessive while combustion flame is brought into close contact with a burner head 9 to heat the main body 6 of a burner to a high temperature. When 7 seconds, for example, has elapsed under this condition, a timer 47 outputs a time-up signal to a relay control circuit. Then, the relay control circuit 24 stops the driving of the pump 12 to stop the supply of kerosene. However, the temperatures of the burner head 9 and the main body 6 of the burner are high and the remaining gas of an evaporating chamber 7 continues to burn, therefore, the amount of discharging of unburnt gas into a room may be reduced remarkably.

Title: Coordinate reader
Inventor: KITAJIMA HIDEKI
IPC: G06F3/0488
Filed: 1993-11-02
Abstract: PURPOSE:To accurately detect a position indicated by a coordinate indicator even at its peripheral part without particularly increasing the size of a coordinate detector as compared with a coordinate reading area by equalizing the intensity of electromagnetic coupling between the 1st exciting loop and detection loop with that between the 2nd exciting loop and detection loop. CONSTITUTION:When the coordinate detector 5 is apart from an exciting line 101 and the 1st and 2nd detection lines 111, 112. the intensity of electromagnetic coupling between a left exciting loop 101a and the 1st detection line 111 is equal to that between a right exiting loop 101b and the 2nd detection line 112, so that the amplitude values of both induction signals S11, S12 become equal to each other. Thereby, when a coordinate detection circuit 4a detects a difference between both the signals S11, S12, induction components generated due to direct electromagnetic coupling between the exciting lines 101 and the detection lines 111, 112 are always negated. When the indicator 5 approaches either one of exciting loops and detection lines, positional information indicated by the indicator 5 can be accurately detected.

Title: Fire sensor
Inventor: MORITA SHUNICHI
IPC: G08B17/06
Filed: 1989-10-24
Abstract: PURPOSE:To confirm the reliability of data stored in the same manner as a specific code by storing the specific code in a RAM and discriminating whether storage of the specific code is accurate or not at each time of fire discrimination. CONSTITUTION:The detection value from a circumstance detecting means FS is stored in a working RAM 2 and is stored in data storage RAMs 3 and 4. The specific code stored in a storage area ROM 2 is stored in a specific code storage RAM 1. The specific code in the RAM 1 is checked before signal processing for fire discrimination; and when it is normal, the difference between the current read detection value and the stored value of the RAM 4 is obtained to perform fire discrimination. When the specific code is defective, fire discrimination is not performed and a past detection value and the present detection value are exchanged. Thus, the reliability of stored data is confirmed.
