A correction value output circuit 30 inputs the pulse p2 to generate a correction value (i) for the correction of the error of the pulse p2 and to set the correction value to the 1920-adic counter 12 when the 1st destination circuit 10 is selected from the 2nd frequency divider circuit 20.  A selector 2 selects the 1st frequency division pulse p1 or the 2nd frequency division pulse p2 to provide an output of the selected pulse.

Title: Cold-setting polymer paving material
Inventor: SAKAMOTO HIROYUKI
IPC: E01C7/30
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To save energy, by using an epoxy resin as a binder for aggregate and specifying the mixing ratio of the epoxy resin and the property. SOLUTION: When a road is paved, an epoxy resin which is a cold-setting polymer paving material, is used instead of asphalt used conventionally. The binder is mixed with aggregate by 3-7wt.%. to secure the dynamic stability and increase the workability. The usable time is longer than 10min, the curing time is shorter than 10 hours, the tensile strength is larger than 5N/mm<2> , and the elongation is larger than 100%, as the properties of the binder. In these conditions, the aimed figures of density, stability, bending strength of the mixture, bending strain of the mixture, etc., can be achieved. In this way, since aggregate or asphalt is not required to heat and hence, energy can be spared and generation of carbon dioxide can be regulated.

IPC: G04G3/00
Filed: 1978-10-04
Abstract: PURPOSE: To form an electron watch equipped with an oscillator which oscillates at a constant frequency under none of influences of external strain and impulsive force, its shape and size, and contamination, by using a resonance frequency of atomic-uncleus quadruplex resonance for the standard of time.  
     CONSTITUTION: In an electronic watch making use of atomicnucleus quadrupole resonance (NQR), LC resonance circuit 1 consists of capacitors C 0 , C 1  and C 2 , vari-cap diodes D 1  and D 2 , and inductance L. Part C 0  is where substance (paradichlorobenzene, potassium chlorate, etc.) 7 showing NQR is sandwiched between electrodes 8a and 8b, covered with plastic molding material 9 and then led out by lead wires 6a and 6b. Since the substance showing NQR absorbs more energy of the LC resonance circuit at a resonance frequency of this NQR, oscillator 1 decreases in output. For the purpose, the output of lock-in amplifier 4 is fed back, so that the oscillation frequency of oscillator 1 can be fixed to the resonance frequency (10∼ 100MHz) of NQR.

IPC: H04B10/077
Filed: 1981-08-06
Abstract: PURPOSE:To prevent erroneous reception of a receiving circuit which photodetects frequency-modulated light into a binary signal, by superposing a signal of optional frequency having lower amplitude than an electric signal obtained by converting received light in the prestage of a demodulator to said electric signal.

Title: Recognition system for pellet positioning
Inventor: SAKURAI YOSHIKI
IPC: H01L21/58
Filed: 1981-08-05
Abstract: PURPOSE:To allow high speed automatic positioning without being influenced by the turbulence of pellet arrangements and further allow setting inferior marks in a mounting process. CONSTITUTION:An IT camera of an image pickup tube type or a two-dimensional solid image pickup element type is used as an image pickup system, and one whereby the surface of a pellet in the field of vision brightens white almost over the entire surface, and the SN ratio between the seat surface becomes large is chosen as an illuminating system. An inputted binary image is transmitted to a mask circuit, and the total number of white or black bits in the image of a set mask part is counted. In an operating circuit, the number of XY pulse motor drive pulses required for position correcting is calculated based on the counted number of each mask and transmitted to a table drive circuit. In a rough positioning, first the counted number of white bits of each mask is compared with each reference value and judged as ''ON'' if over the reference value and ''OFF'' if otherwise. In one screen input, when all of four masks U, D, R, L are determined as ''ON'' by said judgement system, the rough positioning is taken as finished, and an accurate positionig is started.

IPC: H04B10/077
Filed: 1990-05-14
Abstract: PURPOSE:To confirm the timewise system margin by applying phase modulation to a sent transmission signal and varying the phase modulation degree and a modulation frequency. CONSTITUTION:Phase modulation is applied to an input clock signal by a gain adder type phase modulation circuit 6, and phase modulation is applied to a data signal of a data main signal 11-2 at an identification circuit 9 by using a modulation clock signal (f) being an output of the gain adder type phase modulation circuit 6. Moreover, a voltage controlled frequency oscillator 7 is controlled by an output voltage (c) of a monitor control circuit 5 to vary a phase modulation frequency (modulation signal) (a). The other output voltage (b) of the monitor control circuit 5 controls a phase variable circuit 8 to vary an input clock signal phase difference of the gain adder type phase modulation circuit 6 thereby controlling the phase modulation degree. Thus, the timewise system margin is confirmed.

Title: Frequency converting circuit
Inventor: YOSHIHARA YOSHIAKI
IPC: H03D7/12
Filed: 1982-07-14
Abstract: PURPOSE:To attain stable conversion of frequency by reducing the variation of a local oscillating circuit due to an input signal in case of strong input signal. CONSTITUTION:An intermediate frequency signal having the frequency corresponding to the difference between a local oscillation signal applied to the emitters of transistors (TR) Q1, Q2 and a high frequency signal applied to the base of the TRQ1 is taken out from an output terminal Out through an intermediate frequency transformer T1. An emitter follower TRQ5 is connected to the collector side of a TRQ4 for the local oscillating circuit and a local oscillation signal is applied from the emitter of the TRQ5 to the base of a TRQ3 through a capacitor C1. Even if an input signal is applied to the emitter of the TRQ1 through the capacitor C1, the input signal is attenuated because the emitter impedance of the TRQ5 is low, and signal flow from the emitter to the base is reduced, so that the mixing of the input signal to the local oscillating circuit is extremely reduced.
