Title: Ccd image sensor signal processing circuit
Inventor: KAI TSUTOMU
IPC: H04N5/363
Filed: 1991-01-14
Abstract: PURPOSE:To reduce high noise by providing plural variable amplification factor amplifiers, increasing one amplification factor in the case of low illuminance and decreasing the other amplification factor. CONSTITUTION:A CCD image sensor 1 reads image information, outputs a signal to a variable amplification factor amplifier 3 in a preceding step, amplifies the input signal and transmits it to a reset noise reduction circuit CDS circuit 4. The output of the circuit 4 is outputted through a variable amplification factor amplifier 5 in a rear step. In this case, the noise of the circuit 4 itself can be compressed in the case of low illuminance having a high reset removing effect. Thus, in the case of low illuminance, the signal is extended by the amplifier 3 and when the signal is compressed by the amplifier 5, the high noise reduction effect can be realized.

Title: Digital television
Inventor: NAKAMURA JUNICHI
IPC: H04N7/01
Filed: 1985-01-11
Abstract: PURPOSE:To increase an output display data and to improve character visibility by outputting/displaying alternately video data as much as one frame stored once by odd numbered scanning line memories and the like on common liquid crystal scanning lines, while a display panel has horizontal data lines which are one-half of scanning lines. CONSTITUTION:After colors of video signals are separated by a color separator 9, these video signals are converted into a digital signal phi1 of RGB through an analog-to-digital conversion by an A/D converter 10 and are supplied a data controller 11. At the same time, synchronizing signals which are separated synchronization wise by a synchronous separator 7 are converted into a discrimination signal phi5 through a scanning line decision of odd and even numbers and are supplied the data controller 11. Being controlled by the above controller 11, the signal phi1 is supplied a display controller 12. And then it allows a liquid crystal panel 13 to light a lamp and reaches listeners as a picture. Thus when a low-cost digital TV is achieved by simplification of configurations of circuit and its peripheral parts, video information can be transferred to the listeners correctly and distinctly without the need for an output-displaying ability covering the whole TV scanning lines.

Abstract: PURPOSE:To shorten time required for forming a pattern by dividing a pattern to be formed into a plurality of sections, by setting a shift rate which becomes a base according to the pattern density for each section, and then constituting so that the shift rate may be compensated for the reduction side. CONSTITUTION:A pattern data which is separated into a plurality of sections in a section separating circuit 2 is sent to a memory 3 and is stored in it and is also sent to a pattern density calculation part 4. The pattern density calculation part 4 calculates pattern density value for each section and an operation circuit 5 calculates an optimum stage shift rate according to the pattern density value for each section, namely the fastest stage shift rate (basic shift rate) within a range for exposing all patterns within that section. The basic shift rate from the operation circuit 5 is subjected to a specified correction processing considering the upper limit of acceleration/deceleration of stage shift rate sent from a setting circuit 7 in a compensation circuit 8. Then, the basic shift rate after correction is sent to a running trace data retention circuit 8 and is stored as a running trace table.

Title: Inverter device
Inventor: YASUOKA IKUO
IPC: G01R29/16
Filed: 1991-01-17
Abstract: PURPOSE:To detect the open phase of an inverter device from the rate of change in the effective value of a three-phase AC current which varies remarkably time when the open phase occurs in the output of the inverter device by computing the effective value and monitoring the rate of change in the effective value. CONSTITUTION:The output current of an inverter device 1 is detected at a current detecting section 2. Then the effective value IRMS of the output current is computed at an effective value computing section 3 and the rate of change ID in the effective value is obtained through a differentiation circuit section. In order to detect the occurrence of an open phase, the rate of change is always monitored and, when the value of the rate of change ID become larger (¦ID¦<C), the inverter is protected. Therefore, even when the balanced relation among the three-phase outputs of the inverter is broken or the amplitude of the three- phase output current changes at the time of actuating the inverter or in the transient state of a load current, etc., wrong detection of an open phase can be prevented in a transient state by setting the constant C at an appropriate value.

Abstract: PURPOSE:To reduce internal resistance to improve safety at the time of anormality such as a short circuit, by forming diaphragm base body, between both electrodes, of porous resin, joining a hydrophilic group on the surface of the diaphragm base body, and also forming a porous resin film thereon. CONSTITUTION:A battery is formed of positive and negative electrodes and a diaphragm between them, and the diaphragm has a diaphragm base body composed of porous resin. A hydrophilic group is joined and also a porous resin film is formed on the surface of the disphragm base body. Resin, having a solubility parameter of 7.5 or more and 13.0 or less, is used for the diaphragm base body, and resin, having a solubility parameter of 7.5 or more and 13.0 or less, is used for the porous film on the base body surface. Thus closely resembling the solubility parameter values of the diaphragm base body an the porous improves wettability and consequently the blocking property of the pore of the diaphragm base body. Also, affinity between the diaphragm and an electrolyte becomes excellent to reduce internal resistance by joining the hydrophilic group to the surface of the diaphragm base body. Consequently, a battery, which is having low internal resistance and high safety at the time of abnormality such as a short circuit can be provided.

Filed: 1990-01-11
Abstract: PURPOSE:To detect the abnormal position of a film by setting a range wherein an endless film is moved by a meandering control means to be within a dimensional range that the dimension of the shortest part of the endless film is subtracted from that of the longest part in the lateral direction of the film. CONSTITUTION:The film 11 is an endless belt whose diameter is phiM and one side edge part is cut obliquely. When the length of the longest part of the film 11 is denoted as Lmax and that of the shortest part is denoted as Lmin, the dimension of the obliquely cut part DELTAL of the film 11 can be obtained by subtracting Lmin from Lmax. Here, the range wherein the endless film 11 is moved by the meandering control means is set to be within the range of the cut quantity DELTAL. Thus, when the obliquely cut part of the endless film 11 is positioned out of a film position detecting means 16, the abnormal positioning of the endless film 11 can be detected.
