IPC: H01L27/04
Filed: 1990-09-21
Abstract: PURPOSE:To stabilize the substrate voltage while avoiding the deterioration in the holding characteristics by a method wherein the power supply of a buffer amplifier for driving a coupling capacitor in a substrate voltage generating circuit is composed of the resistance division type reference voltage generating circuit by series-connecting to a MOS transistor and a current mirror type amplifier. CONSTITUTION:The reference voltage 4 is generated by a reference voltage generating circuit 1. At this time, an arbitrary voltage can be specified to be the reference voltage by changing the dicision ratio since the circuit 1 is resistance dividable. Next, the reference voltage of the circuit 1 is compared with the voltage of a buffer amplifier 4 by a current mirror type amplifier 2 for actuating the circuit 1 to constantly equalize the power supply voltage of the buffer amplifier 4 with the reference voltage. That is, the specific voltage of 4V can be constantly fed as for the power supply voltage of the buffer amplifier 4 regardless of the fluctuation in the external power supply while the specific voltage of 2V can be maintained as for the substrate voltage. Finally, it is recommended that the voltage of a rated voltage power supply comprising the reference voltage generating circuit 1 and said amplifier 2 shall be set up at the voltage about IV lower than the outer power supply voltage.

Title: Intra-frame vector quantizer/encoder
Inventor: AIDA HISAFUMI
IPC: H04N19/50
Filed: 1985-11-12
Abstract: PURPOSE:To reduce noise included in an input picture signal and to reduce the volume of transmission data by deciding the validity/ invalidity of picture elements in an intra-frame forecasting error signal string and deciding the validity/invalidity of a block obtained by collecting these picture elements. CONSTITUTION:The intra-frame forecasting error signal string 5 found out by a subtractor 4 is inputted to a blocking circuit 7. The circuit 7 compares the inputted signal string 5 with a threshold in each picture element on the basis of a threshold control signal 9 inputted from a transmission buffer 8, and when the signal string 5 is smaller than the threshold, the picture element is processed as an invalid picture element. When it is larger than the threshold, the picture element is processed as a valid picture element. Consequently, a forecasting error based upon noide 1 included in an input image signal 1 and invalid picture elements are increased. Then, '0' is applied to picture elements decided as the invalid picture elements. An average value separated/normalized vector quantizer/encoder 11 quantizes the dispersion of the average value and outputs the vector-quantized index in the valid/invalid block as a quantized output 12.

Title: Method for driving plasma display panel
Inventor: AWAJI NORIYUKI
IPC: G09G3/28
Filed: 1990-09-20
Abstract: PURPOSE:To reduce the cost of a plasma display panel by the lowering of the breakdown strength proof of a circuit element by always impressing a bias voltage equal to or under a discharge starting voltage on an address electrode and impressing the address voltage over the discharge starting voltage on the address electrode at the time of selecting light emission. CONSTITUTION:The discharge maintaining pulse of a negative polarity and the bias voltage of a positive polarity equal to or under the discharge starting voltage are always impressed on main discharge electrodes 13 and 14 and the address electrode 22, respectively. At the time of selecting light emission in a unit light emitting area, the write pulse of the negative polarity is impressed on the electrode 13 instead of the discharge maintaining pulse and the address voltage over the discharge starting voltage is impressed on the electrode 22. Thus, discharge is caused at the intersection of the electrodes 22 and 13. The discharge of a discharge maintaining electrode pair 12 is caused by the discharged charge, and the light emission in the unit light emitting area is kept by the following discharge maintaining pulse. At such a time, it is necessary to control the voltage of a value obtained by subtracting the bias voltage from the address voltage for the electrode 22, and the charge amount accumulated on the electrode pair 12 side is restrained to such an extent that self erasing discharge is not caused.

IPC: C01B32/50
Filed: 1988-10-07
Abstract: PURPOSE: To reduce the investment and running cost for suppressing condensation by equipping the interior of an another vessel with a membrane system, thermally insulating this vessel and heating the vessel, thereby maintaining desired overheating with respect to the feed gas to be passed to the membrane system. CONSTITUTION: A dialysis membrane system 13 houses a membrane module capable of selectively permeating a more easily permeable component within a feed gaseous stream from a not so much easily permeable component. A heat supplying means 11 superheats the feed gas stream before passing the feed gas to the dialysis membrane system 13 and supplies heat to the extent of heating the feed gas under the feed gas pressure to a temp. higher than its saturation temp. to the feed gas stream. Further, the thermally insulated vessel 9 encloses the membrane system 13 and the means 11 and suppresses the loss of the heat so as to prevent all the heat loss from increasing larger than the heat supplied by the means 11 and to maintain the superheating state with respect to the feed gas stream to be passed through the membrane system 13.  As a result, the condensation of the component of the feed gas stream in the membrane system 13 is effectively prevented and the stable uniform adjustment of the temp. in the membrane system 13 is maintained.

Abstract: PROBLEM TO BE SOLVED: To unnecessitate a standard light quantity generation device, a special support system, etc., by deciding the existence of pixel defects based on the output characteristics of a photoelectric conversion element to be tested with respect to incident light quantity which is found by changing an incident light quantity. SOLUTION: An output of the neighborhood area of a pixel to be tested is selected, the median y0 of each output level is extracted by a median filter, and the output level of an normal pixel is found. The incident light quantity (x) of the pixel to be tested is calculated by the expression x=(y0-b0)/a0. The a0 is the mean reference photoelectric coefficient of each normal pixel and the b0 is similarly the reference offset output level. The y0 is respectively found with respect to prescribed input light quantity and is substituted to the expression, and each incident light quantity is determined by inverse calculation. The photoelectric coefficient and the offset output level are derived from these incident light quantities and each actual output level by the method of least squares. Thus, it is possible to prescribe the existence/aboence and kind of a pixel defect.
