Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To detect reception quality quickly with a simple configuration by providing a binarizing means binarizing a digitally modulated reception signal and a reception quality detector detecting the quality of the reception signal, based on a binarized wave form. SOLUTION: A reception quality detector 37 uses pulse generators 28, 29 to receive a binarized digital modulation waveform outputted from a binarizing quantization device 17 of a digital demodulation section 9 and to output positive/ negative pulses respectively. A pulse generator 33 detects an output from an OR device 32 and generates a positive pulse. An exclusive OR device 34 outputs an exclusive OR sig 34 between an output waveform from the OR device 32 and a pulse waveform from the pulse generator 33. A smoothing circuit 35 smoothes an output of the device 34. An amplifier circuit 36 outputs a signal sig 36 resulting from amplifying an output signal of the circuit 35.

Title: Optical information recording and reproducing device
Inventor: ATSUTA YASUSHI
IPC: G11B7/125
Filed: 1985-08-20
Abstract: PURPOSE:To suppress variance in the peak intensity within a prescribed range by stopping down a light beam having an elliptical distribution as an elliptic optical spot on an information recording medium without being shaped into a circular distribution and correcting the irradiated power corresponding to a horizontal lighting angle of a semiconductor laser. CONSTITUTION:The light beam having an elliptic distribution irradiated from a semiconductor laser is collected and stopped down without being shaped into a circular distribution. Thus, the light spot having an intensity distribution with an elliptic cross section is irradiated on the information recording medium. In emitting the semiconductor laser without using a beam shaping means such as a shaping prism or a cylindrical lens from the relation between the peak intensity when the irradiated power from the aperture lens in the elliptic light spot is constant and the variance of the irradiated angle of the semiconductor laser, the peak intensity depends only on the horizontal irradiating angle and the effect of the vertical irradiating angle is neglected. Thus, the peak intensity is made constant by correcting the irradiated power from the aperture lens for setting in response to the horizontal direction irradiating angle.

Title: Active signal discrimination circuit
Inventor: KAGOHASHI SATORU
IPC: H04L25/02
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To reduce the number of adders, to simplify a logic circuit and to reduce the scale of a circuit configuration by parallelly connecting respective full adders and discriminating whether received data are valid or invalid corresponding to whether the number of active H in the received data at a certain time point is '1' or plural. SOLUTION: Full adders from 1-m to 1-1 successively connecting plural (m) pieces of steps successively perform addition from the lower-step adder 1-m to the higher-step adder with received data H/L of all (n) pieces of parallel signals at a fixed point of time as a binary number, and a carry output C0 of each full adder and an sum output S0 of the final adder 1-1 are inputted to a logic circuit part 2. When all the carry outputs C0 of the respective full adders from 1-m to 1-1 are 'L' and the sum output S0 of the final step 1-1 is 'H', the received data at that time point are judged valid and a discriminate signal is outputted. Thus, since the discrimination is enabled without finding the number of all the active H, the number of full adders is reduced, the logic circuit part 2 is simplified as well and the entire circuit configuration can be made small in scale and simplified.

Title: Picture communication equipment
Inventor: MIURA SHIGEO
IPC: H04N1/21
Filed: 1986-08-04
Abstract: PURPOSE:To eliminate the need for a special key and a complex operation, to efficiently use a telephone line, a memory and a recording paper and to improve the efficiency in time by receiving the telephone reservation from a reception side only at the time of completing the transmission of a last page while memory is transmitted. CONSTITUTION:Though the last page isn't completed the transmission while a facsimile transmits the memory, a signal for the purpose of the telephone reservation is transmitted from the receiver side and the signal is neglected. When a transmitter transmits a last page finish signal EOP, the receiver receives the signal and transmits a telephone reservation signal PIP to the transmitter so as to convert it to the state of call again. The transmitter receives the signal and makes a sound emitting body 7 ring so as to demand a transmitting subscriber to raise the telephone receiver. When the subscriber receives it and raises the telephone receiver, the transmitter transmits a call request signal PRI-EOP to the telephone receiver, then controls an NCU 2 and converts the line into the telephone side to be in a holding state. Therefore even at the time of transmitting the picture from the memory the telephone reservation can be possible and the useless transmission isn't executed in order to save resources.

Abstract: PURPOSE:To keep the image quality of a recording image well at a low energy level, by providing heat generating parts arranged corresponding to a picture element density on a heat signal applying means and bringing the dimension of each heat generating part extending along in the direction crossing the arrangement direction of the heat generating parts at a right angle to specific relation with respect to the center-to-center distance of the heat generating parts. CONSTITUTION:For example, the distance alpha between the end part of each of heat generating resistors 21 and the end part of a head main body 1 is set to 50mum, the center-to-center distance lambda of the heat generating resistors 21 is set to 125mum and the width dimension deltaof each heat generating resistor 21 is set to 80mum and, further, the dimension l of each heat generating resistor 21 extending along in the direction crossing the arrangement direction of the heat generating resistors 21 at a right angle is appropriately set within 2lambda. The contrast of the surface temp. distribution of ink 3 along the longitudinal direction of a slit opening part 2a becomes large as the dimension l becomes small and position shift between an ink heating region and an ink flight region is scarcely eliminated and a high quality recording image is obtained. When the dimension l becomes equal to 2lambda, positional shift begins to generate slightly. Further, as the dimension l becomes small, the application quantity of energy can be suppressed to a small amount.
