Title: Digital filter circuit
Inventor: HONDA SHIGE
IPC: H03H17/02
Filed: 1986-05-09
Abstract: PURPOSE:To apply digital filter processing corresponding to number of coefficients generated by three adders, one multiplier and two latch registers by using a coefficient generator generating a determined coefficient storing. CONSTITUTION:A counter 102 counts from one to ten, and the coefficient generator 103 outputs prescribed coefficients K1, K2-K7 when the output of the counter 102 is 1-7 and outputs zero when the output is 8-10. A picture data inputted from an input terminal is latched by the 1st latch register 101, multiplied with a coefficient generated correspondingly by a multiplier 104 and the result is outputted to the adder 105. The adder 105 and the 2nd latch register 106 constitute an accumulator, which accumulates the result until the counter 102 reaches 7, and is initialized by using a clear signal 107 generated by a clear signal generator 108 when the counter 102 reaches ten. Thus, a picture element data subjected to 7 stage of filters is obtained at an output terminal in the rate of one picture element per ten picture element inputs.

IPC: G11C17/00
Filed: 1985-05-16
Abstract: PURPOSE:To restrict a through type current and to prevent the increase of a consumed current and to attain high speed by connecting the second electric charge precharging MOS transistor between a data line to which a memory section is connected and a power source potential point. CONSTITUTION:An electric charge precharging N-type transistor 35 connected between a power source point and a data line 2 inputs a clock signal phi1 having a complementary relation to a clock signal -phi1 impressed to the gate of the N-type transistor 13 of a memory section 1. Thereby, even if a precharging period is shortened and the high speed is attempted, the potential Vx1 of an input end of an inverter 30 can be completely charged during a precharging period, so that when a AND logic is not accomplished, the lowering of this potential Vx1 can be remarkably small, the an increase of a consumed current can be restricted without the through type current in the the inverter section 30 and the output potential of the inverter section 30 is stabilized.

Abstract: PURPOSE:To enable the accurate prediction of a production completion time and the schedule control of a plurality of production machines to be performed by recogniz ing the starting time and completion time of one production cycle by changes in and the combinations of a plurality of contact signals indicative of the operating conditions of the production machines. CONSTITUTION:The starting time and the completion time of one production cycle are recognized by operating condition recognizing means 1 by changes in and the combinations of a plurality of contact signals indicative of operating conditions extracted from production machines. When one production cycle is completed, actual production results are increased by one by actual production results computing means 2 and a mean cycle time is calculated by mean time calculating means 3 on the basis of the production cycle time obtained by the means 1. A scheduled production is inputted by scheduled production input means 4 attached to the production machines. In production completion time predicting means 5, production results are subtracted from the scheduled production to obtain the residual scheduled production and, by multiplying the residual scheduled production by the mean cycle time, a production completion time is predicted. Further, a prediction thus obtained displays the present state in color and a remaining time on the screen of a display means 6.

Title: Method for preventing corrosion of metal and corrosion inhibitor
Inventor: OKUMA MASATSUNE
IPC: C23F11/167
Filed: 1989-04-25
Abstract: PURPOSE:To produce a significant corrosion inhibiting effect on an iron-based metal by using specified amts. of a specified phosphonium salt and a specified zinc compd. as chemical substances to be added to a water system coming in contact with the iron-based metal. CONSTITUTION:A tetrakis(hydroxymethyl)phsphonium salt and a Zn compd. capable of readily releasing Zn ions in water are added to a water system coming in contact with an iron-based metal at >=4mg/l and >=1mg/l concn., respectively. The upper limit of the concn. of the phosphonium salt is not particularly limited but about 50mg/l is fit for the upper limit because an enhanced effect corresponding to the increase of the concn. cannot be expected when the concn. exceeds about 50mg/l. About 30mg/l is fit for the upper limit of the concn. of the Zn compd. for the same reason.

IPC: H04L27/36
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To suppress expansion of a spectrum attended with phase modulation. SOLUTION: This modulator is constituted of a phase shifter 11 that converts a digital signal into 2-series of orthogonal signals and outputs the signals so that a period when a self phase change of a multilevel digital signal displayed on orthogonal axes is π/2 (rad) is in existence without fail in the case of a state transition of the received digital signal, a band limit filter 12 applying band limit to an output of the phase shifter 11 and a phase modulator 13 applying phase modulation to the output of the filter 12. Since the state transition is caused at π/2 (rad), expansion of a spectrum in the nonlinear amplifier 3 is suppressed and conversion distortions of AM/AM and AM/PM are relaxed.

Title: Optical pulse reception circuit
Inventor: YOKOYAMA MAKOTO
IPC: H04B10/50
Filed: 1985-05-17
Abstract: PURPOSE:To receive an optical pulse signal without distortion with standardized intensity by providing a photoelectric conversion circuit consisting of a photodiode and an operational amplifier and a comparator circuit. CONSTITUTION:In receiving an optical pulse A, an output B of an operational amplifier OP1 is inputted to a comparator circuit COM while its waveform remains distorted. On the other hand, since a voltage applied to a capacitor C is charged while a voltage at a point A is at high level and discharged via a resistor R1 when the voltage is at a low level, waveform C is obtained. In selecting the resistor R1 as a value so that the capacitor C is nearly discharged when a dark state for several pulses continues, then the voltage C corresponds to the maximum pulse voltage for nearly several pulses. Since nearly the same waveform as that at the point A is applied to an inverting input of an opera tional amplifier OP3, nearly the same waveform voltage as a voltage at a point B is applied to an output point C. The voltage at the point C is divided by resistors R2, R3 to form a voltage at a point D. A comparator circuit COM compares the quantity of the waveforms B and E, resulting that an output voltage F is caused. Thus, a pulse train without distortion with standardized strength is received.
