Title: Yarn guide
Inventor: SOROE KAZUNORI
IPC: C04B35/48
Filed: 1989-01-31
Abstract: PURPOSE:To provide the yarn guide which has excellent strength and wear resistance, can guide yarn well and hardly generates yarn breakage even when used over a long period of time by using zirconia ceramics incorporated with crystals of specific grain sizes as the material for the yarn guide. CONSTITUTION:This yarn guide for fishing yarn or fibers, etc., is formed by using the zirconia ceramics which consists mainly of 0.3 to 0.8mu crystals, is incorporated therein with <=50% crystals of 1 to 3mu grain size in terms of volume, and contains 10 to 60mol% crystal of the monoclinic crystal. The crystal grain size of the above-mentioned material tends to increase with an increase in the content of the crystals of the monoclinic crystal system and to decrease with a decrease in the coefft. of dynamic friction. The ratio of the monoclinic crystal is required to be >=10mol% in order to deposit the relatively large crystals of 1 to 3mu as mentioned above. However, the deterioration in strength is significant if the ratio of the monoclinic crystal exceeds 60mol% and, therefore, the material in which the ratio of the monoclinic crystal is confined to 10 to 60mol% is most excellent.

Title: Transmission system
Inventor: ADACHI KAZUO
IPC: H04L5/22
Filed: 1982-02-15
Abstract: PURPOSE:To simplify the constitution of a transmission system in which analog values at plural information generation points need be collected to one place concurrently in terms of time, by omitting a sampling command station and a sampling command transmission line. CONSTITUTION:An RTu1 which is farthest from an MTu4 sends out a frame 8 for data transmission in every sampling synchronism of the system. Respective RTu1-RTu3 regared the reception timing of a synchronizing word SYN9 as sampling timing to perform A/D conversion and transmit the data to the MTu4 together with alloted slots. To time synchronizing words to sampling, dummy slots 13-14 corresponding to the data establishment time at the RTus are provided between the allotted slots and synchronizing words to the RTus1-3. Consequently, the RTus perform sampling at different timing because the synchronizing words are timed to the sampling. Thus, a device and a transmission dedicated to sampling commands are omitted, so the constitution of the system is simplified.

IPC: G01R29/02
Filed: 1990-02-01
Abstract: PURPOSE:To always obtain a constant counted result without receiving the effect of tape feeding speed by measuring a capstan speed input from the posi tive pulse to the negative pulse and from the negative pulse to the next positive pulse of a reproducing control signal. CONSTITUTION:A D(data)FF 6 obtains an output showing positive and negative period in synchronism with the rising of the speed input from a capstan speed input terminal 2. A counter 9 executes counting by taking the capstan speed input terminal 2. A counter 9 executes counting by taking the capstan speed input from the terminal 2 as clock input and inputs an output signal from the DFF 6 so as to count up the period from the positive pulse to the negative pulse of the reproducing control signal from a reproducing control signal input terminal 1 and count down the period from the negative pulse to the next posi tive pulse. The counted value of the counter 9 is different according to the duty of the reproducing control signal but constant to the change of a cycle, thereby discriminating the duty of the reproducing control signal. The DFF 10 reads in the duty discrimination output and holds it till the rise of the next positive pulse.

Title: Image reader
Inventor: FUKUDA SATOSHI
IPC: H04N1/403
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To promptly and easily discriminate soiling on a white reference board or a reading surface by performing shading correction to input data by using read data and detecting the soiling by binarizing the input data. SOLUTION: Output of a circuit 8 for storing a shading wave form at shipment is inputted in a correction coefficient converting circuit 6 and the shading correction is performed by a correction coefficient multiplication circuit 3. Since a soiled part is binarized as black of an image signal by binarizing the wave form with a high slice level, existence of the soiling on the white reference board or the reading surface is discriminated by easily discriminating whether or not black is included in a binarized result in a control circuit 5. In addition, the size of the soiling is detected by changing the size of the slice level. Consequently, the soiling on the white reference board and the reading surface is detected without increasing a scale of the circuit and an excellent shading correction is constantly performed.

Title: Nonlinear distortion compensating device
Inventor: TAKABAYASHI SHINICHIRO
IPC: H04B7/005
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a nonlinear distortion compensating device which does not require large operating amount by performing nonlinear distortion compensating operations, by not performing multiplication of complex numbers in a base- band zone, but by performing phase adjustment on orthogonal local signals and amplitude adjustment on the signals after quadrature modulation. SOLUTION: A nonlinear distortion compensating device first compensates the distortion of the phase components of transmitted orthogonal base-band signals 101 by finding a power value 103 of the signals 101 and adjusting the reading-out positions of ROMs 107 and 108 for storing orthogonal local signals based on the power value 103. Then the compensating device compensates the amplitude components of the signals 101, by multiplying the signals quadrature modulated by means of a quadrature modulating section 109 by a factor which compensates the amplitude components, based on the power value 103. Thus, a compensation device which does not require multiplication of complex numbers in a base-band zone is obtained.

Filed: 1979-03-02
Abstract: PURPOSE:To facilitate the removal of a magnetized body from an electromagnet yoke, by providing a separation coil for generating a magnetic field in the opposite direction to that by a magnetization coil, on the yoke fitted with the magnetization coil on which the magnetized body is placed. CONSTITUTION:A magnetization coil 2 is fitted, as woven, in the eight grooves of an electromagnet yoke 1, which extend from its periphery to center. A separation coil 3 is wound under the magnetization coil 2. Pins 4 are provided on the peripheral part of the yoke 1. A magnetized body 5, which comprises a gear-like magnetic pole disc 5a and a ferrite disc 5b located thereunder, is placed on the yoke 1 so that the magnetized body is surrounded by the pins 4. An electrical current is caused to flow through the magnetization coil 2 to magnetize the body 5. After that, the current is cut off and another current is caused to flow through the separation coil 3 to generate an inverse magnetic field. The attractive force between the magnetized body 5 and the yoke 1 is thus reduced to facilitate the separation of the magnetized body 5. As a result, the magnetized body 5 is not flawed and the efficiency of work is improved.

Filed: 1993-01-21
Abstract: PURPOSE:To prevent a radio communication system where the SN ratio is never deteriorated after demodulation despite the reduction of the reception power in an FM communication system. CONSTITUTION:In a bidirectional radio communication system where two points are connected together by a frequency modulated wave, at least one of both radio stations measures the reception power of the signal received from the radio station of the opposite party side (22). The modulation index of the radio wave sent from a radio station to the opposite party side is controlled based on the measured reception power so that the signal received from the opposite party station has a prescribed SN ratio. Then the band widths of the variable BPF 18 and 30 which transmit transmission/reception modulated waves of the relevant radio station are properly controlled in response to the modulation index.
