Title: Shading correcting circuit
Inventor: SUMITA KAZUYUKI
IPC: H04N1/40
Filed: 1985-08-20
Abstract: PURPOSE:To obtain a shading correcting circuit which contains no correction mechanism in its optical path system and is never affected by the change with the lapse of time of the light quantity of a light source like a fluorescent lamp, etc., by proportionating the reference voltage of an A/D converting part corresponding to a picture signal to a shading wave form. CONSTITUTION:When a power supply is applied, a control part 8 starts a photoelectric transducing part 3 and an address counter 6. At the same time, an analog switch 9 selects the reference voltage Vs corresponding to the maximum dynamic range of the output of the part 3 out of a reference voltage generating part 10 in the form of the 1st reference voltage of an A/D converting part 4. When a transmission original is read and scanned, the shading data is read out a line memory 5 for each line as soon as the scan of the original is started and then converted into analog signals by a D/A converting part 7. In response to this operation, the 2nd reference voltage VD is produced from a reference voltage generating part 11. Then the part 4 performs the A/D conversion of the read-out picture signals of the transmission original based on the reference VD.

Title: Electromagnetic clutch of electromagnetic type booster
Inventor: SHIMIZU YASUO
IPC: F16D27/115
Filed: 1984-09-03
Abstract: PURPOSE:To reduce noise and permit the smooth transmission of a necessary torque by applying a mechanical multiple-disc clutch onto the electromagnetic clutch of an electromagnetic type booster and reducing the connection noise on clutch connection. CONSTITUTION:When an electromagnetic coil 44 is in excitation state, magnetic fluxes are formed around the vacant space which an elliptical hole 43 forms.

IPC: A61B8/00
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To make echoes strong in a target line penetrating into an examinee to be measured, by tilting scanning beams so that each scanning beam becomes almost vertical to the target line based on the angle between the target line set in the examinee to be measured and an ultrasonic vibrator. SOLUTION: A punctual needle 3 is punctured into a human body with along a penetration path guide 4 by fitting a punctual needle adapter to an ultrasonic vibrator 1 placed on the human body 2 surface. Then the angle θ of the punctual needle 3 to the ultrasonic vibrator 1 is determined by this punctual needle adapter. This angle θis inputted to a control part. The control part determines a display position of the penetration path guide 4 by arithmetic calculation and displays it on a display. Further, the delay times of each vibrator cell are controlled so that the scanning beams from the ultrasonic vibrator 1 become almost vertical to the punctual needle 3. Thus, the transmission wave beams and the reception wave beams become vertical to the stab needle 3 which receives strong echoes in the position of the punctual needle.

Title: Digital signal modulating system
Inventor: SHINOJIMA YASUSHI
IPC: H04L27/00
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To shorten the width of one bit and to accelerate communication by recognizing data during the first 'L' or 'H' period of one bit, shortening and omitting the following 'H' or 'L' period. SOLUTION: Corresponding to digital data, data '0' are composed of signals having different duty ratios and frequencies, namely, composed of the period 'L' of 2x and the following period "H" of (x) and data '1' are composed of the period 'L' of (x) and the period 'H' of (x). Therefore, the length of the data '1' is shortened into the 2/3 length of data '0' and set. These transmission data are transmitted after its pulse width is modulated and on the reception side, received data composed of serial data sequences are generated by specifying the signals by detecting the duty ratios by edge detection. Thus, since the unwanted 'H' period is shortened, the transfer time of one bit can be shortened.  Besides, when the data '1' and '0' are competed, the data '1' are embedded in the data '0' and are not outputted so that the contention can be detected, the transmission can be stopped and the destruction of other transmitting data having higher priority can be prevented.

Filed: 1984-09-06
Abstract: PURPOSE:To exclude troublesome adjustment of an analog filter in a conventional system and to miniaturize the circuit scale by introducing a transversal filter as a means using a matching filter for filtering a discriminated data after a delay. CONSTITUTION:The transversal filter consists of plural stages of D flip-flop (FF)32 shifting a discriminating data in a clock frequency (f) by a clock period 1/nf (n is a positive integer) sequentially, plural resistors 33 applying weighting to an output of each D FF32 in matching with the impulse response of a transmission line and an adder 34 summing outputs of the resistors 33. A weighting in response to an error signal epsilon is applied to an output of the adder 34 by a weighting device 26 and the result is fed back negatively to the input of an identification device 23. Since the filtering characteristic of the digital filter is decided definitely by the resistors 33, the constitution and its handling are simplified.

Abstract: PROBLEM TO BE SOLVED: To guarantee a slantly moving property and excellent water stop property across a long term by mounting a spacer elastic body with a lower hardness than that of a rubber packing in a clearance between the receiving port and insertion port of the inside of the rubber packing. SOLUTION: A rubber packing 2 is stuck to the inner surface of a receiving port 1 molded by a plastic by an adhesive and a spacer elastic body 3 is provided on the back of the rubber packing 2.

Even if the insertion port 5 is slanted for the receiving port 1, sufficient water stop property can be held by approaching the width center position of the rubber packing 2 to the fulcrum position of the slant.
