Title: Wave dividing and synthesizing method for radio equipment
Inventor: YOSHIDA TAMAAKI
IPC: H04J1/06
Filed: 1983-03-14
Abstract: PURPOSE:To make it unnecessary to design a frequency characteristic for dividing filters with high precision and to divide waves without influences of adjacent dividing filters by separating sequence of dividing filters to an even channel sequence and an odd channel sequence to divide waves. CONSTITUTION:Transmitters 2 are connected the even channel side and the odd channel side individually. The even channel-side transmission signal and the odd channel-side transmission signal synthesized by transmission dividing filters 1 are transmitted by a transmission antenna 3. In the reception side, the signal received by a receiving antenna 6 is distributed to the even channel side and the odd channel side by a distributor 7 and is divided to individual radio channels by reception dividing filters 4 and is outputted to a receiver 5. For the purpose of compensating the distribution loss of the distributor 7, an amplifier 8 is used to perform preamplification. Consequently, a high-precision characteristic is not required for dividing.

Title: Counter correction circuit for video signal
Inventor: KIJIMA TAKAYUKI
IPC: H04N5/208
Filed: 1991-02-14
Abstract: PURPOSE:To attain optimum contour correction and to eliminate a noise component by implementing the correction so as not to lose a level of a contour signal thereby implementing base clipping. CONSTITUTION:A contour signal generated by a contour signal generating circuit 2 is given to a base clip circuit 3, in which only a noise elimination level preset for the contour signal is clipped. Then the contour signal whose noise level is clipped is given to an amplitude correction circuit 4, in which the amplitude is corrected so that the level is the same as the original contour signal and after the gain is adjusted by a gain control circuit 5, the result is added to the original video signal by an adder circuit 6. Thus, regardless of an input video signal level, accurate and well-balanced contour correction is implemented and deterioration in S/N is not caused.

Abstract: PURPOSE:To aim at reduction in a setting space and improvement in the reset characteristic of a shockless piston by letting a poppet member, forming a damper chamber partivively, hold a function of a check valve, and making a seat part diameter of this poppet member larger as specified. CONSTITUTION:Relief valves 3, 4 partition a damper chamber 38 with a shockless piston 30 and a sleeve 35 constituting a poppet member 19, while they make up a check valve allowing only flowing into an interconnecting passage 39. With each closure of two main passages 1, 2, if high pressure oil is discharged to the passage 1, by way of example, with inertia of a hydraulic motor (m), it flows into a shock absorbing chamber 32 by way of a through hole 19b, a secondary pressure chamber a pass hole 21a, a passage 41 and a slit 40, whereby the poppet member 19 opens a large diametral seat part 18a against a spring 22 through a pressure differential by an orifice 19c. In addition, with movement of the sleeve 35, the shockless piston 30 closes each of pass holes d1, d2 in order as throttling each of them for deceleration. Thus, reduction in a setting space is well promoted and, a reset characteristic of the shockless piston is improved.

Abstract: PROBLEM TO BE SOLVED: To reduce power consumption for illumination and miniaturize circuit configuration by utilizing external light for illuminating the surface of an original by a sensor, and only when light quantity is lacking, using an illuminating equipment. SOLUTION: A scanner body is moved and the surface of an original is scanned to read out the surface of the original by a CCD in a sensor 6. Normally the sensor 6 is illuminated by external light, but when the level of an analog signal outputted from the sensor 6 is low, a signal is sent from a circuit arranged in an A/D converter 10 and capable of detecting the output level of a video signal outputted from the sensor 6 to an illuminating equipment 7 to turn on a lamp or an LED. A read original, picture is converted into an electric signal by the CCD and outputted. The video signal outputted from the sensor 6 is converted into a digital signal by the A/D converter 10 and inputted to a shift register 13. The register 13 shifts the video signal synchronously with a reference pulse supplied from a reference pulse generating circuit 15.

Title: Water feeding devive
Inventor: TSUJI AKIO
IPC: F04B23/00
Filed: 1978-04-10
Abstract: PURPOSE: To prevent a pump driving motor from damage due to over-loading in a water service device by utilizing the syphon distroying action effectively so that any leakage of large quantity will not occur in the piping.  
     CONSTITUTION: While a pump 2 is in operation, the water sucked from an intake reservoir 1 by the pump 2 flows through the piping 4 in full state and reaches the drainage area 7. If the pump 2 is stopped, a syphon distroying valve 9 comes into operation to suck in the air for the purpose of syphon distruction and the water in the piping 4 is separated to the upper and lower stream sides of the piping 4 with the highest position 8 as the critical point. At this time, the water in the upper stream side of the piping 4 is checked to flow back to the intake reservoir 1 by the action of a check valve 5, so that water leakage is prevented. Consequently the frictional loss in the initial period of restarting of the pump 2 becomes nearly as large as the one under continuous operation, so that overflow of water can be prevented as well as damage of the pump driving motor due to over-loading can be prevented.

Filed: 1983-03-11
Abstract: PURPOSE:To detect errors with a high precision without the influence due to the waveform distortion of a clock signal supplied from a receiver by adding a clock reproducing function to a false error detector. CONSTITUTION:The signal supplied from the receiver to this false error detector is only a base band signal before demodulation. An extractor 12, a tank 13, and a limiter 14 reproduces a clock signal from the base band signal inputted to a terminal 6. This reproduced clock signal is supplied to the first and the second samplers 9a and 9b through the first and the second phase shifters 10a and 10b. The second phase shifter 10b shifts slightly the phase of the clock signal supplied to the second sampler 9b, and the second sampler 9b samples the base band signal at a time elapsed by DELTAT from the Nyquist point. The output of the second sampler 9b is the reproduced data having the degraded quality and the error rate of this output signal is called a false error rate, and the false error pulse is outputted to an output terminal 8 in accordance with a receiving signal.
