Patent JP-S63308416-A (JP)
Title: Delta modulator
Inventor: MURAKI KENJI
IPC: H04B14/06
Filed: 1987-06-10
Abstract: PURPOSE:To obtain a delta modulator which generates a small quantization noise by using plural quantizers and making a majority decision among their outputs. CONSTITUTION:When the output of a comparator 12 is in a part E, D flip-flops (DFF) 13, 14 and 15 output 'H', so the output of an OR gate 19 is also 'H'. In a part F, the DFFs 14 and 15 are outside a blind sector and output 'H'. Even if the DFF 13 malfunctions to output 'L', the output of the OR gate 19 becomes 'H', which is correct. A part G is the blind sector of the DFFs 13 and 14, but the DFF 15 outputs 'H', so the output of the OR gate 19 is wrong only when both DFFs 13 and 14 output 'L'. When the appearance probabilities of 'H' and 'L' in the blind sector are half and half, the probability that a part G malfunctions is 1/4. In a part H, the DFFs 13, 14 and 15 are all in the blind sector, so the malfunction probability of the OR gate 19 is 1/2. Thus, a majority decision among the outputs of the three DFFs is made to narrow down the blind sector apparently and a quantization error can be reduced.

Title: Engine tachometer driver
Inventor: YAMASHITA SHOJI
IPC: F02D45/00
Filed: 1987-06-10
Abstract: PURPOSE:To achieve a higher response characteristic of an engine tachometer, by driving the engine tachometer by a fundamental drive pulse corresponding to a rate of change in an engine revolutions signal and an added drive pulse corresponding to a rate of change in a load signal of an engine. CONSTITUTION:Two pulses A and B are generated according to the rotation of a crank shaft of an engine from a pulse generator 1. The pulse A is generated once each rotation of the engine while the pulse B is generated once each time the crank shaft rotates by a fixed value. The pulse B provides an engine rotation signal varying in the frequency thereof with changes in revolutions of the engine. With such an arrangement, the pulse B is supplied to a CPU 2 and a rate of change in the engine revolutions signal is detected to make a fundamental drive pulse of an engine tachometer 9. A throttle valve opening signal changing according to a load generated from a throttle valve opening sensor 11 is supplied to the CPU 2 and a rate of change in the opening of the throttle valve due to variations in load is detected to make an added drive pulse signal of the tachometer 9. This eliminates a delay in response of the tachometer 9 with the driving of the tachometer 9 by both fundamental and added pulse signals thus obtained.

Abstract: PURPOSE:To provide a method for producing the black base material of a car interior material in which a white or other nonwoven fabric except a black one is used as a raw material and a pre-process for dyeing this nonwoven fabric in black is not necessary. CONSTITUTION:A white spin-bond nonwoven fabric 2 (100%, 30 to 50g/m<2> of polyester) is fed by a roller 3 to a solution tank 1 in which 99% of water, soluble phenol resin is mixed with 1% of azo dye. The nonwoven fabric is impregnated with the mixed solution of the amount of impregnation 50g/m<2>. The obtained impregnated nonwoven fabric 2A is fed to a drying furnace 5 by a roller 4, and dried for 80 seconds by using steam at temperature of 130 deg.C to have a volatile component of 8 to 10%. The dried nonwoven fabric 2B is cut to a predetermined size by a cutter 6. A three-layer plate 8 formed by providing the two cut nonwoven fabrics 2C and 2C on the upper and lower sides of a rock fiber 7 is placed in a forming die 9 with the prescribed form of a car interior material and thermally pressed. The azo dye with which the cut nonwoven fabrics 2C and 2C are impregnated becomes black and the water soluble phenol resin is cured owing to heating at this time, so that the black base material 10 of the car interior material with the prescribed form can be obtained.

Title: Multiplex signal transmitter and multiplex signal receiver
Inventor: KAWAI KIYOYUKI
IPC: H04N7/08
Filed: 1989-06-07
Abstract: PURPOSE:To eliminate need for an expensive 3-dimension movement adaptive Y/C (luminance signal/chrominance signal) separator circuit by applying frequency multiplex to a luminance broad band signal to a luminance signal region and applying frequency multiplex to a chrominance broad band processing to a chrominance signal region. CONSTITUTION:A high frequency component YH of a Y signal (board band processing of luminance) is subjected to frequency multiplex to a tilt high frequency of a low frequency component YL of the Y signal and a high frequency component QH (chrominance broad band processing signal) of a Q signal are subjected to frequency multiplex to a tilt high frequency of a high frequency component of an I signal. Thus, before a color difference (I, Q signal) is subjected to orthogonal modulation with a chrominance carrier SC1 at the sender side, the high frequency component QH is subjected to frequency multiplex and a C signal is subjected to orthogonal demodulation with a chrominance subcarrier SC1 at the receiver side, then the high frequency component QH is separated. Then each component is separated at a 2-dimension frequency region and the need of use of an expensive 3-dimension moving adaptive Y/C separator circuit is avoided.

Abstract: PURPOSE:To measure an effective value of an extremely low frequency sine wave at a high speed by bringing a sine wave to full-wave rectification, and thereafter, detecting an amplitude value by a peak holding circuit and a sample holding circuit and measuring the effective value. CONSTITUTION:A distortionless sine wave of a period T1 inputted to a full-wave rectifier 1 is brought to full-wave rectification as shown by a dotted line in the figure, brought to peak holding 2 during a period T2 as shown by a full line in the figure, and thereafter, set by a reset pulse of pulse width T2, and repeated in a T2 + T3 period. This peak holding waveform is brought to sample holding 3 by the nearest value to a peak value of the end of the period T2. Accordingly, when a period of a sampling pulse is denoted as T4, T4 = T2 + T3 is obtained. These periods T2, T3 and the period T4 are determined by a timing pulse generating circuit 4. Subsequently, an output of the circuit 2 is brought to A/D conversion 9, and a prescribed relation existing between an amplitude value and an effective value is calculated by a CPU 10 and displayed 11 as an effective value voltage on a display 11 by a segment LED.

Filed: 1994-06-03
Abstract: PURPOSE:To improve the reliability in information reading and writing by enhancing the smoothness of an ABS surface in the case of forming the ABS surface into a crown shape. CONSTITUTION:The ABS surface 28 and its rear surface 30 of a slider are subjected to both side lapping and thereafter, the ABS surface 28 is subjected to one side lapping so as to be accompanied with shrinkage. As a result, the entire part is so deformed that the ABS surface 28 side is recessed and the rear surface 30 side is projected. However, the ABS surface 28 itself is maintained in a flat state since its recessed shape is shaved by the lapping. The rear surface 30 is thereafter subjected to the one side lapping so as to be accompanied with shrinkage. As a result, the entire part is so deformed that the ABS surface 28 side is projected and a crown is formed on the ABS surface 28. Therefore, the ABS surface 28 is smoothed and the crown is formed.

Title: Rubber roll
Inventor: SATO SEIJI
IPC: B65G39/06
Filed: 1987-06-10
Abstract: PURPOSE:To improve durability remarkably by orientating radially a heat- resistant short fider in a diametral direction, by a method wherein the heat- resistant short fiber is mixed into synthetic rubber in a specific quantity in an orientated state. CONSTITUTION:An aramide fiber or a carbon fiber is favorable as a heat- resistant short fiber to be mixed with rubber raw materials and a matter having the diameter and an aspect ratio to the extent of 5-30mum and 100-1000 respectively is used. A mixture ratio of the heat-resistant short fiber with rubber is 0.5-10pts. per 100 pts. rubber and when the same is 0.5 pts. or lower, production effect is small for its production cost. Then when the same is 10 pts. or higher, mixing into the rudder becomes difficult, and wear resistance and compression-resistant permanent distortion become worse. The optimum mixture ratio is an extent of 2-5pts. Then as aramide short fiber as the heat-resistant short fider is added and mixed with natural rubber or synthetic rubber especially NBR or fluorine rubber, the modulus of elasticity and tensile strength are improved remarkably.
