IPC: G05B11/36
Filed: 1980-03-05
Abstract: PURPOSE:To reduce a control error without excessively raising the operation frequency of an apparatus to be controlled, by varying a blind sector set point in accordance with the operation frequency of the apparatus to be controlled. CONSTITUTION:The difference of a target value which has been set by the target value setting device 1, and a measured value which has been obtained by the detector 2 is provided to the control judging part 5 by the subtracter 3. On the other hand, the blind sector is provided once as an initial value to the reversible counter 10 by the blind sector setting device 4, and the output of the counter 10 is used as  an actual blind sector. The control judging part 5 compares a control error provided by the subtracter 3 with a blind sector provided by the reversible counter 10,  and outputs a control command to the apparatus 6 to be controlled. The said part 5  always monitors the operation frequency of the apparatus 6, and outputs a command 11 for increase to the counter 10 when the operation frequency has been raised, so that the blind sector is enlarged. On the contrary, when the operation frequency has been lowered, the part 5 outputs a command 12 for decrease in order to  make the blind sector small. In this way, a control error can be reduced without  excessively raising the operation frequency of the apparatus 6.

The signal C is inputted to a preamble n-symbol carrier phase estimation circuit 41 and a clock phase estimation circuit 70, and the carrier phases are estimated every (n) symbols to an arbitrary carrier phase. The output C of a sample circuit and the output R of a carrier filter 100 are inputted to a detection circuit 50, and a demodulation signal H, including no carrier phase error, is outputted. The carrier phase errors can be decreased, because the carrier phases are estimated in sequence and for every (n) symbols.

IPC: H04N19/50
Filed: 1984-02-20
Abstract: PURPOSE:To also make a plural receiving system of an encoding system between acting compensation frames sufficiently endurable by changing over, when detecting a transmission error, posterior encoding system to an encoding system between acting compensation-free frames. CONSTITUTION:In an encoding system between acting compensation frames, information created by shifting previous frame information based on an acting compensation information can be a part of new frame information. After an error occurs, continuous use of this encoding system could shift a part of erroneous information stored in a frame memory 260 in a receiving device 2. Therefore, for the purpose of fixing an erroneous information position on the memory 260 for easy detection of the erroneous position, along with entrance of an erroneous position detecting mode, the system changes over the encoding system using an action as 0 (or virtually the encoding system between acting compensation-free, simple frames).

Title: Interface facilitating communication of periphery with both synchronous or asynchronous system
Inventor: SUUNIRU JIYOOSHII
IPC: H04L29/06
Filed: 1988-02-10
Abstract: There is disclosed herein an interface for a peripheral to allow the peripheral to communicate with either synchronous or asynchronous systems. The interface includes a series of flip-flops coupled in a chain to take the combined data strobe and chip select signals from an asynchronous system such as a microprocessor and synchronize the combined signal with the peripheral clock and convert the signal to a pulse. This pulse then emulates the instruction enable pulse received from synchronous microprogrammed systems. If the peripheral is operating in a synchronous system, the instruction enable signal from the system is gated through a multiplexer controlled by a mode signal which indicates which mode is active so as to act as the peripheral instruction enable signal. An AND gate gates one bit of the instruction bus with the ANDed chip select and data strobe signals to create a read/write control signal for interval use in controlling the data bus drivers.

Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst filter having a large contact area and high contact frequency but extremely small filtration resistance. SOLUTION: A specified amt. of a catalyst prepared in a fine powder state is added to a pulp suspension liquid of about 0.1% density (generally the amt. of the catalyst is several times the fiber amt.), and mixed and suspended, to which a specified amt. of all flocculation assistant (depending on the kind of the catalyst, and for example, a melamine colloid or aluminum polychloride) is added and stirred. Further, a proper polymer flocculant and high pressure air-saturated water in proper amts. are also added and stirred to cause strong adsorption of the fine powder catalyst to the fiber surface. In this stage, microbubbles of air produced from the high pressure air-saturated water deposit as bubbles on the fiber 1 so that the fiber 1 adsorbing the catalyst 2 floats to form a deposited layer of fiber containing lots of microbubbles of air on the water surface.  The deposited layer is transferred to a metal mesh, dehydrated in vacuum without pressurizing, and dried to complete the production of a filter.

Filed: 1981-03-02
Abstract: PURPOSE:To prevent a tape from being applied with an excessive tension by shortening the time of operation by releasing braking force to a reel turntable where the tape comes to the operation position through the one-directional rotation of a motor and by locking the tape at the no-operation position through the opposite roration. CONSTITUTION:In fast-forward mode, the 1st and 2nd motors 30 and 42 turn to move main rod 36 and subrod 54 to the right through groove 52 of gear 50 with a cam and pin 38, and then projection 62 and pin 14 are unlocked mutually to bring idler 22 into contact with pulley 28, thereby rotating the take-up reel turntable. On detecting a tape end, motor 42 reverses and the engagement between gear 50 with the cam and arm 72 with a pawl rotates subrod 54 to press projection 62 against pin 14, thereby stopping the take-up reel turntable. Therefore, the braking means is released through the one-directional rotation of motor 42 and put in operation through the opposite rotation, so that the operation during the said actions can be quickened.
