Title: Privacy call device
Inventor: HIRAIDE JUNJI
IPC: H04L9/06
Filed: 1990-07-30
Abstract: PURPOSE:To enhance the privacy call performance by decoding a data based on the result of decoding of an address data ciphered by a pseudo random signal. CONSTITUTION:An address data included in a signal from a communication line in the case of reception is fed to a microcomputer 6 via a serial/parallel conversion circuit 10 from a changeover circuit 8. Then the address data is fed to a storage circuit 3 from the microcomputer 6 to read relevant initial value data D1-D6, a stage number setting data and a tap position setting data. A decoding circuit 11 uses a pseudo random signal to decode accurately the ciphered data from the changeover circuit 8 and outputs the resulting data. Thus, it is not required for the receiver side to enter a signal key, and the sender side revises freely a cryptographic key and the secrecy of the communication is sufficiently kept.

Title: Image writer
Inventor: MASUDA KOJI
IPC: H04N1/19
Filed: 1986-08-29
Abstract: PURPOSE:To lower memory cost, by constituting the valid write width of a write head at a succeeding stage smaller than that of the write head at a preceding stage. CONSTITUTION:Two write heads 21 and 22 are arranged so as to be shifted with each other in a scanning direction, and a writing valid width is extended longer than ever. At this time, the valid width l22 of the write head 22 arranged at the succeeding stage is set narrower (shorter) than the valid width l21 of the write head 21 arranged at the preceding stage. To write an image on the same line correctly, a picture signal is impressed on the write head at the succeeding stage with a timing delayed by a prescribed time behind impression on the write head at the preceding stage. Since the write width of the write head at the succeeding stage is set narrower than that of the write head at the preceding stage, it is possible to reduce the memory capacity of a buffer in which the picture signal being impressed on the write head at the succeeding stage, is stored transiently.

Filed: 1985-09-12
Abstract: PURPOSE:To prevent excessive compression from occurring as well as to reduce a degree of driving force and aim at simplification in structure, by balancing air pressure and demand pressure with a specific piston, and closing a check valve at that point that the pressing air pressure to be fed to pneumatic apparatuses reaches to the demand pressure. CONSTITUTION:A stroke of a piston 18 in an air pump 14 is being set so as to cause maximum pressure P1 inside a pressure chamber 16 to bome a compression ratio in a manner conformable to almost balancing with the sum total of demand pressure P2 and resilient force of a valve spring 25. Therefore, at that point that feed air to an air cylinder 12 reaches to the demand pressure P2, force acting on both pressure receiving surfaces of a valve body 24 of a check valve 19 becomes balanced, whereby the valve 19 is maintained to a normally close state. In consequence, an air quantity inside the pressure chamber 16 is kept constant, and excessive compression is prevented from occurring, while driving force is reduced to the utmost. In addition, direct drive takes place with a motor whereby a structure inclusive of various elements for securing the driving force is simplifiable.

IPC: G06F1/08
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To permit the image forming device which processes image data by using frequency spread technology to perform excellent image formation by suppressing the generation of beat noise. SOLUTION: Video data (default data at the time of a black document) outputted from a CCD line sensor 405 when read operation is performed while a light source is turned off are equivalent to beat noise included in video data obtained when read operation is performed while the light source is turned on. Once beat noise data are stored, a correction memory 409 subtracts correction data stored in a correction data storage part 412 from video data read by a normal method while the light source is turned on to perform a correcting process for removing the beat noise. After the beat noise is thus removed, image formation is performed under the control of a printer control part 413 and then an image where no beat noise appears can be obtained as an output image.

IPC: F02D19/06
Filed: 1984-09-28
Abstract: PURPOSE:To shift the supply of plural kind of fuels to an engine by inputting a detected signal of the load of a generator or the flow rate of a fuel, calculating the time of shifting the fuel to one which agrees with the signal by means of a control unit, and operating a selector valve by means of an actuator. CONSTITUTION:At the time of warming up operation using an A-heavy oil, a control unit 13 calculates the quantity of the A-heavy oil that an engine 1 has consumed, based on the detected signal of a generator load 7 from a load detector 11 and the set value of the lowest flow rate of fuel on unloaded time from an unloaded-time lowest flow rate of fuel setter 12. And, when this quantity has reached a certain value, a shifting operation signal is outputted to an actuator 14, and a selector valve 5 is shifted to a C-heavy oil side. When a command of stopping the engine 1 is issued, the control unit 13 outputs an operation signal for shifting to an A-heavy oil to an actuator 14, and the selector valve 5 is shifted to an A-heavy oil side. As a result, the consumption of the costly A-heavy oil can be suppressed to the minimum.
