Title: Grinding method for non-true circle of shaft structure
Inventor: SHIOZAWA MAKOTO
IPC: B24B1/00
Filed: 1986-10-22
Abstract: PURPOSE:To obtain a true circle of the section of a shaft structure under the condition of its use, by obtaining a distortion amount, given to the shaft structure so as to decrease its distortion to zero, from a measured valve of the distortion, generated similarly to that in the condition of use, and giving the distortion amount similar to said distortion in a normal temperature to the shaft structure. CONSTITUTION:A shaft structure 1 is ground to a true circle in a normal temperature, and distortion of the shaft structure 1 under the condition of its use is measured in each position in the peripheral direction for the true circle 10 in that time. After measurement is finished, on the basis of a measured value, the shaft structure 1 is ground to a non-true circle so that the distortion in the normal temperature, that is, the displacement of size from a radius of the true circle 10 decreases to zero under the condition of use. After grinding the shaft structure 1, if it is placed in the condition of use, the shaft structure 1 of true circle is obtained. In this way, when the shaft structure 1, ground to the non-true circle, is placed in the actual condition of use, the shaft structure 1, forming its sectional shape to the true circle, can be prevented from deflecting when the shaft structure 1 rotates.

Title: Cable telephone system
Inventor: NAKAO MASAHARU
IPC: H04N21/2383
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To enhance the secrecy of communication data by applying bit shift processing to shift a data string with an error correction code added thereto to a tail end of the data string by a prescribed amount from the head of the data string and sending the resulting data string with shift amount data. SOLUTION: In the cable telephone system utilizing a network of a 2-way broadcast system, transmission data are fed to a transmission data generating circuit 54, in which the data are divided into data bit strings and an error correction code addition circuit 55 adds an FEC error correction code to the tail end of each data string. Based on shift amount notice data outputted from the transmission data correction circuit 54, the data string of one unit consisting of an information bit string + FEC is divided to conduct the rearrangement processing to shift bits ranging from the head to a bit designated by the shift amount notice data, to the tail end of he FEC. Then the result is outputted to a transmission line via an output circuit 57 with the shift amount notice data. A receiver side conducts reverse processing to the processing above to make demodulation.  Thus, the secrecy of communication data is enhanced with a simple configuration.

Title: Control system for servo-motor
Inventor: KAZETO HIROHIKO
IPC: G05B7/02
Filed: 1988-10-06
Abstract: PURPOSE:To improve servo-performance by switching a speed control system to a proportional-plus-integral control (PI control) or a delay control by a deviation between a position feedback from a machine system and a position command. CONSTITUTION:A speed control is switched to a PI control 2 or a delay control 3, based on speed information of a machine from a position feedback, and distance information from a difference between a position command and the position feedback to a target position. That is, switching of the speed controls 2, 3 follows up the PI control 2 in a dynamic friction area in the vicinity of the target position, and when it enters into a static friction area and becomes an overshoot as it is, it is switched to the delay control 3. In such a way, the overshoot is small, and also, it is possible to approach a command position, comparing with executing only the delay control from the beginning.

IPC: H04Q11/04
Filed: 1991-10-01
Abstract: PURPOSE:To prevent overflow in a buffer. CONSTITUTION:Each cell storage decomposition section 600 receives a cell through a signal line 41 and corrects a correction time stamp in each cell additively based on prescribed information given from a control section 500 through a signal line 51 and stores the cell till the correction time stamp corrected exceeds the time stamp given from the control section 500 through a signal line 50 and decomposes the cell when the time stamp is exceeded to output information from a medium to a decoding section 700. A buffer control section 900 monitors number of cells stored in the cell storage decomposition section 600 and when number of cells exceeds a prescribed number, a control signal is outputted. Upon the receipt of the control signal, the control section 500 corrects the prescribed information additively and outputs the result to the signal line 51. As a result, number of cells outputted from the storage decomposition section 600 is increased, the number of stored cells is decreased and overflow is prevented.

Title: Cross color reducing device for carrier chrominance signal
Inventor: KUMANO MAKOTO
IPC: H04N9/78
Filed: 1992-09-22
Abstract: PURPOSE:To reduce a scale and cost by detecting the degree of a non-inverse phase between the output of a delay device provided with specific delay time and an input carrier chrominance signal and reducing an output level corresponding to the degree. CONSTITUTION:The delay time of a field memory 2 for outputting an input carrier chrominance signal 1 containing a cross color while delaying it by one field is defined as 263 horizontal scanning period +N/fsc. In this case, N is an integer, fsc is a carrier color frequency and 263 shows a line number. A detector 3 inputs the input carrier signal and the output of the memory 2 and detects the degree of the non-inverse phase between both of signals. When the amplitude of x+y is larger than each component amplitude of (x) or (y) according to the input/output characteristic of the memory 2, a controller 4 decreases an output signal. Therefore, the cross color can be decreased, further, the output level is decreased, and the device can be constituted with the small scale at low cost. In this case, the x axis stands for the input signal level value of the delay device 2, and the y axis stands for the output level of the detector 3.
