Title: Active matrix display device
Inventor: NAKAJIMA SETSUO
IPC: G02F1/133
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To improve image quality by providing the device with constitution obtd. by arranging thin-film transistors(TFTs) in respective pixel electrodes arranged in a matrix form and setting a field-through voltage smaller than the voltage necessary for one gradation. SOLUTION: Peripheral driving circuits are composed of shift register circuits 201, NAND circuits 202, level shift circuits 203 and buffer circuits 204 for driving active matrix circuits 205. The active matrix circuits 205 comprise the TFTs 206, auxiliary capacitors 208 and liquid crystals 207. All the circuits are composed of the TFTs formed on the same glass substrate. The feed-through voltage is set smaller by the voltage necessary for one gradation in order to suppress the degradation in the image quality by the variation of the feed-through voltage. The value itself of the feed-through voltage is set smaller in such a manner, by which the influence of its fluctuation is lessened and the high image quality is obtainable.

Title: Image input device
Inventor: KAGAMI YOSHIJI
IPC: H04N1/04
Filed: 1988-10-05
Abstract: PURPOSE:To input an image irrelevantly to the kind of a body to be read by detecting the kind of the body to be read automatically and selecting a proper read means. CONSTITUTION:When the body to be read is inserted, a CCD sensor 18 detects information indicating whether the body to be read is a transmission or reflection type and information on the width of the body to be read in the form of the quantities of photodetection by the CCD. A CPU 40 matches the guide plate 5 of a read body conveying means and a slit plate with the width of the body to be read by motors 21 and 23 according to the width of the body to be read. Further, motors 22 and 35 are driven to convey the body to be read. The CPU 40, on the other hand, connects a switch 43 to a transmission type CCD sensor 25 when the body to be read is the transmission type or to a reflection type CCD sensor 26 when the body to be read is the reflection type. Consequently, both the transmission and reflection type documents are readable.

Title: Preamplifier
Inventor: KAWASHIMA SEIICHIROU
IPC: H03F3/08
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To process the received signals of various modulation systems via a single amplifier by reducing the noises in a low frequency area and widening the band in a high frequency area. SOLUTION: An input optical signal is converted into a current signal by a photodetector 10 and outputted through a feedback part 13 when the input impedance of an amplifier 12 is sufficiently high. The output voltage varies by the frequency characteristic that is increased and reduced in the low and high frequency areas respectively of the feedback resistance value of the part 13. At the same time, the output voltage undergoes the band limitation by the input impedance of the amplifier 12 and the parasitic parallel capacitance of the photodetector 10. Thus the amplifier 12 can reduce the noises in an AM modulation system where the severe noise characteristic is required in a low frequency area and can widen the band in an FM and QAM modulation systems where the wide band characteristic is required in a high frequency area.

Title: Document preparing device
Inventor: TAKAHASHI HIROMASA
IPC: G06F17/21
Filed: 1984-11-30
Abstract: PURPOSE:To read and confirm in succession plural documents prepared by a simple operation from an external part memory by installing a quick-viewing mode function to read in succession plural prescribed documents from the external memory. CONSTITUTION:When an operator wants to confirm the prepared document, a quick-viewing mode of the document is designated from a work menu displayed on the screen of a CRT 14. Thus, a CPU 10 calls out a file name, a head address and the number of the address of the document, an object, from a catalog area of an external memory 12, stores them to a main memory 11 and displays the contents to the screen of the CRT14. Like this, when the operator selects the quick-viewing mode from the first work menu, plural documents are in succession read from the memory 12 and displayed at the CRT 14 only by the operation of the quick-viewing key. Consequently, plural prepared documents are read and confirmed in succession from the external memory only by the simple operation.

Title: Pulley and ball bearing therefor
Inventor: TOYODA TSUKASA
IPC: F16H55/36
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To check or prevent any noise from occurring in time of cold by installing a plastic cage where each axial one side of plural pieces of pocket storing and holding a ball is set to a ring base part and the other side to an opening part respectively, and setting up a guiding part, being guided by an outer ring or inner ring, in this cage. SOLUTION: A cage 2d is equipped with two pockets 3 at circumferential equal positions, and the axial one side is a ring abse part 4 and the other side is an opening part 5, and the peripheral edge is a concave spherical surface. A tongue piece 8 is continuously extended in the outer diametral side tilting direction from the outer diametral side part of a pillar part 7 of this cage 2d, and then a guide part 9 is installed in a tip part outer diameter of the tongue piece 8. When an outer ring 2a is rotated, the cage 2d is dragged around as being pulled by the outer ring 2a by the effect of contact between the guide part 2d and the outer ring 2a and viscosity of an oil film existing between both of them, therefore it comes into contact with a ball 2c by dint of undue contact force.  With this contact force, the ball 2c receives revolutional force from a peripheral edge of the pocket 3, whereby its axial behavior is regulated. With this, a self-excited vibration of the ball 2c is restained, and thus any noise in time of cold is controlled.

Abstract: PURPOSE:To increase the efficiency of the titled heat exchanger, by constituting the heat exchanger by assembling a rotary heat exchanger part of regenerative heat permeating type on the outer side, and a rotary heat exchanger part of regenerative type on the inside. CONSTITUTION:An air flow A and an air flow B flow into the elements 24 and 25 of a rotary heat exchanger part 16 of regenerative, heat permeating type, flowing out of the openings on the periphery of a heat exchanger, in the upper part of a heat exchanger partitioned into the upper and the lower parts by a bulkhead 29. The inside ends of diaphragms 19, 19 among the element 24 and 25 are positioned close to the outer side from the center of a circle. This structure provides large internal passages. Pressure loss is small in the air flows A and B, so that highly efficient heat exchanging can be taken place in the passages. The air flow B only flows into a rotary heat exchanger part 15 of regenerative type in the center, flowing out of the openings on the periphery of an outer heat exchanger part 16, guided by flow guide members 26. The heat exchanger part 15 has internal passages of which diameters are equal both in the center part and on the outer periphery, so that the air flow B can flow uniformly and heat is accumulated uniformly as well. When a heat exchanger body rotates and comes to a position in the lower part divided by a partition plate 29, the air flows A and B are changed reversely, and are circulated to the elements 24 and 25 of a heat exchanger part 16.

Title: Noise canceller
Inventor: KARIYA TETSUO
IPC: H04B1/10
Filed: 1991-10-01
Abstract: PURPOSE:To reduce mis-recognition of a regular pulse as an irregular pulse due to noise in the regular pulse by outputting a pulse detection signal from a comparison means based on a front edge detection signal and a pulse trailing edge confirming signal. CONSTITUTION:Pulse front edge detection means 1-3 detect a pulse front edge of an input signal and output a front edge detection signal after a prescribed time (e.g. 2mus). Moreover, pulse trailing edge confirming means 4, 6, 7, 8 detect a pulse trailing edge of the input signal to detect whether or not there is a change in the input signal within a prescribed time (e.g. 0.6mus) from that point of time. When any change is in existence, the trailing edge is neglected and when no change is in existence, a pulse trailing edge confirming signal is outputted. Then comparator means 5 outputs a pulse detection signal based on the front edge detection signal outputted from the means 1-3 and the pulse trailing edge confirming signal outputted from the means 4, 6, 7, 8. Thus, mis- recognition of a regular pulse as an irregular pulse due to noise in existence in the regular pulse is reduced.

Title: Method and device for displaying image
Inventor: NAKAMURA YASUNORI
IPC: H04N5/445
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for displaying an image capable of improving discrimination property of a character displayed overlapping a background image. SOLUTION: A background image and a discrimination image containing a character overlapped with the background image are acquired (S1, S2). A watched pixel value changed by the total density value of pixels constituting the character incorporated in the vicinity area of respective pixels of the discrimination image is obtained as to the respective pixels of the discrimination image (S3, S4). The density values of respective pixels of the background image corresponding to the respective pixels are adjusted according to the watched pixel values of respective pixels of the discrimination image (S5-S8). Therefore, since the density difference between the background image and the character is increased in the vicinity of the character, the character becomes easy to see. That is, the discrimination property of the character displayed overlapped with the background image is improved.
