Title: Semiconductor integrated circuit device
Inventor: OKAMURA HITOSHI
IPC: H01L27/06
Filed: 1989-03-27
Abstract: PURPOSE:To obtain high electrostatic breakdown strength by providing an NPN transistor and a C-B diode as an electrostatic protection circuit, and constituting a bypass circuit having superior response to negative pulse. CONSTITUTION:When a positive voltage pulse with respect to a power supply line 4 is applied to an input terminal 3, an NPN transistor Tr1 operates as a bipolar transistor, and makes a bypass current flow in the power supply line 4. When a negative voltage pulse is applied, a C-B diode 6 whose response is superior to a parasitic C-Sub diode 5 of the Tr1 operates in the forward direction, and forms a current bypass. The diodes 5, 6 are formed in the same process: the collector is connected with the input or the output terminal 3 of the Tr1; the emitter is connected with the power supply line 4 via a resistor 2. As mentioned above, the current is rapidly bypassed regardless of the polarity of input pulse, so that no load is applied to the Tr1, which can be prevented from destruction.

Abstract: PURPOSE:To recognize the pattern of a picture by extracting the feature quantity of the picture at high speed and with high accuracy, by performing the extraction of the (n) pieces of feature vectors in parallel by using (n) pieces of memories. CONSTITUTION:By assuming plural straight lines l11-l1i drawn at a regulated interval in the line direction of a memory 1, finding the sum of the values of pictures 2 positioning on respective straight line, the sum of the number of the picture elements 2 painted in black existing on respective straight line can be obtained. Assuming those as C11...C1i, the first feature vector C1 setting those as elements can be obtained. Similarly, by assuming plural straight light lines l21...l2i drawn at the regulated interval in a direction different from the straight line within the range of an angle of 180 deg., and finding the sum of the values of the picture elements 2 positioning on respective straight line as C21...C2i, the second feature vector C2 setting those as the elements, can be obtained. Similarly, (n) pieces of feature vectors can be found by changing the angle, and the pattern recognition of the picture can be performed by using those (n) pieces of feature vectors.

Title: Paper supply device
Inventor: MAMIYA TOSHIHARU
IPC: B65H3/06
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a roller by providing a roller with an annular surface layer part made of an elastic material, forming the surface layer part with an annular first and second parts axially arranged, and making an outer diameter of the roller of the first part larger than that of the roller of the second part. SOLUTION: A pick-up roller is formed by a frictional member 2 comprising two large diameter parts 2-a and a small diameter part 2-b formed therebetween, and a core member 3 having a mounting part 3-a and a flange part 3-b of the frictional member 2. At the start of use, two large diameter parts 2-a of the frictional member 2 are contacted with a sheet material to feed the sheet material. When the frictional coefficient is decreased due to the change of the surface condition of the large diameter part 2-a caused by consumption, the feeding force is impaired, the slippage is generated between the large diameter parts 2-a and the sheet material, the large diameter parts 2-a are shaven by the sheet material, which reduces the outer diameter, so that the small diameter part 2-b makes contact with the sheet material.  Since the surface condition of the small diameter part 2-b is not deteriorated, the sheet material can be fed without slippage.

Title: Television signal transmitter
Inventor: ABE YOSHIO
IPC: H04N7/00
Filed: 1987-03-27
Abstract: PURPOSE:To expand an aspect ratio while providing compatibility to an existing television system by superimposing a video signal at both sides of the screen to make the screen aspect ratio longer laterally within a band of a television signal subjected to residual-side band amplitude modulation and inverting alternately the positive modulation and negative modulation of the superimposed signal. CONSTITUTION:A carrier wave P1 obtained from an oscillator 24 of an orthogonal modulation circuit 4 is subjected to amplitude modulation by an amplitude modulator 22. The amplitude modulation wave is subjected to band limit by a 1st filter 23 and formed in the residual-side band and the result is fed to an adder 29. The carrier wave P1 is shifted in terms of phase by 90 deg. by a phase shifter 25 as a carrier wave P2. A multiplex signal inputted from a multiplex signal input terminal 26 is used to apply double-side band amplitude positive modulation to the carrier wave P2 by the positive modulation circuit 27 and negative modulation is applied by a negative modulation circuit 28. The modulated signal is selected alternately by each horizontal period or a field by a selection circuit 29. The selected signal is subjected to band limit by a 2nd filter 30 and fed to an adder 31. Thus, a multiplex signal is superimposed on a conventional video signal to form the synthesized television signal.

Filed: 1980-06-05
Abstract: PURPOSE:To realize a variation of stereophonic feeling or spread for a sound image to be reproduced, by adding the signal of the opposite channel to the signal of each channel of a stereo set and at the same time varying the level of the signal to be added. CONSTITUTION:When stereo signals -L and -R are obtained at terminals 1L  and 1R of a stereo demodulating circuit 1, these signals are supplied to the base of  transistors (TR) Q1 and Q2, respectively. Thus L+DELTA1R and R+DELTA1L are obtained at the collectors of the transistors. At the same time, signals -L and -R are supplied to the base of TRSQ3 and Q4, respectively, and also L-R and R-L are obtained at the collectors of these transistors since they constitute a differential amplifier. Then TRSQ5 and Q7 as well as Q6 and Q8 use the TRSQ3 and Q4 for a constant current source, respectively. Thus signals DELTA2(L-R) and DELTA2(R-L) are obtained at  the collectors of TRSQ5 and Q8, and the coefficient DELTA2 varies by the value of voltage EC. As a result, the addition signals of opposite channels are obtained through speakers 4L and 4R, and the spread of a reproduced sound image can be varied by changing the value of voltage EC.
