Patent JP-S6294019-A (JP)
Title: Switching circuit
Inventor: YOKOSUKA AKIYASU
IPC: H03K17/615
Filed: 1985-10-21
Abstract: PURPOSE:To lower power consumption by arranging Darlington connection transistors (TRs) between an input TR and an output TR to make the current consumption nearly constant even when the quantity of the output current change. CONSTITUTION:When an output current I0 is small, a constant current I1 from a constant current source CS flows to a base of a TR Q6 thereby supplying a base current IB to an output TR Q2. On the other hand, when the output current I0 is increased, the saturation voltage of the output TR Q2 rises and a TR Q5 is conducted. Thus, since the base current to the output TR Q2 is supplied also from a load current I0 by the conducted TR Q5 when the output current I0 is increased, the current consumption ICC is made nearly constant.

Title: Memory checking method
Inventor: ITOU TOMOJI
IPC: G06F12/16
Filed: 1982-12-28
Abstract: PURPOSE:To check an RAM and an ROM memory without interrupting a system by checking the RAM and ROM memories and storing the check result in the free time of program execution. CONSTITUTION:A memory check program is executed in the free time of the program of a computer system. When the RAM is checked, stored information is transferred to a temporary storage means and then an RAM check pattern is written in the RAM and read out; and this read RAM check pattern is compared with the written RAM check pattern to check whether the RAM is normal or not, and the information stored in the temporary storage means is returned to the RAM. When the ROM is checked, the initial value of a check sum value is set and the contents of the ROM are read out successively to calculate check sum values, which are compared with preset check sum values in a normal state, deciding whether the ROM is normal or not.

IPC: G09G3/36
Filed: 1985-10-21
Abstract: PURPOSE:To eliminate a flicker and to select picture elements in a short time by impressing pulses to scanning lines when a back light is off or in relatively dark periods before and after that and then selecting picture elements. CONSTITUTION:Pulses are impressed to scanning lines when the back light 10 is off or in a relatively dark period before or after that to select picture elements. Then, a liquid crystal panel 1 holds a scanning electrode 2 at 3V0 and a display electrode 4 at 0V, and then holds the electrode 2 at -2V0 to control the potential of the counter electrode 4 according to two states of 'dark' and 'light'. Namely, when '1' or 'dark' is selected, the electrode 4 is held at +V0 and then a voltage -3V0/d where (d) is the distance between electrodes 2 and 3 is impressed from the electrode 2 to the electrode 4 to produce an electric field in the opposite direction from last operation and picture elements are inverted to write 'dark'. When '0' or 'white' is selected, the electrode 4 is held at -V0 and then the voltage from the electrode 2 to the electrode 4 is -V0/d to maintain 'light' selected in the last operation.

Title: Electro-optical device
Inventor: HIRAKATA YOSHIHARU
IPC: G02F1/1343
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To solve such problem as a narrowness of a visual angle which a liquid crystal display has, and to display a clear image by providing a first electrode connected to the drain of a thin film transistor and a second electrode extending from a common wire and disposing the first and second electrodes in a spiral so as to mesh with each other. SOLUTION: A picture element 103 connected to the drain of a thin film transistor 100 is surrounded by a common electrode 105 and is separated from a gate wire 101 and a source wire 102. Therefore, since it can be inhibited that the picture element electrode 103 is influenced from the gate wire 101 and the source wire 102 by fixing the common electrode 105 to a predetermined potential, a clear and accurate image having no bleeding on a periphery of the picture element can be indicated. Further, since a pair of electrodes 103, 105 are spirally extending toward a center vicinity in one picture element so as mesh with each other, an influence due to an interference from a neighborhood formed on an end of the electrodes is exhibited little.

IPC: H04N1/19
Filed: 1990-09-03
Abstract: PURPOSE:To attain highly accurate detection by including a 1st process in which a grating pattern arranged regularly in one direction is picked up to lead out an image pickup signal and a 2nd process outputting a visually confirmed output picture from the pickup signal and detecting the connection deviation in the scanning direction of joints of plural photoelectric conversion elements depending on moire stripe in an output picture. CONSTITUTION:At first a picture scanning section 10 carries a test chart 18 in a subscanning direction (in a direction of arrow X) and longitudinal lines 22 and lateral lines 24 are read by a picture read section 12. Then image pickup signals are processed as a picture signal forming a main scanning line 30 by a signal processing section 14 and the result is led to a picture output section 16. Moire stripes take place on the reproduction picture of longitudinal lines 22 based on a difference between a spatial frequency caused by a pitch of the longitudinal lines 22 and a spatial frequency caused by a pitch of a photoelectric conversion section 38 forming CCDs 26a-26d. Similarly moire stripes take place on the reproduction picture of lateral lines 24.
