Title: Logic circuit
Inventor: KANEKO KENJI
IPC: H03K19/082
Filed: 1980-03-18
Abstract: PURPOSE: To simplify the process of manufacture and to increase an operation speed by using a pnp transistor having constant current characteristics as a load and an npn transistor with a Schottky diode for clamping as a driving transistor.  
     CONSTITUTION: As loads, pnp transistor TRP21 and 22 having constant current characteristics are used and as driving TRs, npn TRN21 and 22 with a clamping Schottky diode are used to constitute an inverter two-stage circuit. Since this constitution uses only one kind of the Schottky diode, only one kind of a metallic electrode is used. Further, the loads are located at the collector sides of the driving TRs. The collectors of driving TRs and inputs of the next-stage gates are coupled direct. Consequently, the operation speed is increased as compared with that of C 3 L and the process of manufacture can be simplified.

Title: Color liquid crystal display device
Inventor: KIMURA YUJI
IPC: G02F1/1333
Filed: 1990-02-15
Abstract: PURPOSE:To obtain the color liquid crystal display device which has the low probability of the disconnection of wirings and a good contrast by varying the areas of picture element electrodes with each of the picture elements corresponding to respective colors of color filters. CONSTITUTION:The color filters of the same thickness are provided and the areas of the picture element electrodes 4 are varied in correspondence to the respective colors of the color filters. Namely, the area ratios of the respective picture elements R, G, B are specified to 30:59:11 in such a manner that the output ratios of R, G, B respectively attain 30%, 59%, 11% like a color TV in order to obtain, for example, a full-color display. Since the output intensity of R, G, B varies with materials, such as the transmittance and color intensity of the color filters, the area ratios are adjusted by taking the conditions, such as materials, into consideration in such a manner that the ratios of the output intensity attain 39:59:11. Color slurring is prevented by disposing the color filters on the outer side (the opposite side of the liquid crystal layer) of a substrate 1. The steps of the wirings are eliminated in this way and the disconnection is substantially prevented. The color liquid crystal display device which is free from the color slurring and has the good display contrast is thus obtd.

IPC: G01B11/30
Filed: 1984-02-28
Abstract: PURPOSE:To improve the detection precision of surface defects by preventing advantageously degradation of S/N of defect signals due to variance of illumination to a material to be examined and variance of the temperature of the material itself. CONSTITUTION:With respect to an electric signal from a photoelectrically converted visible region light, a bias is applied to the signal of level ''0'' between video signals by an unblanking circuit 1, and the preprocessing of low-pass filtering processing is performed. After the input signal is so adjusted in an AGC circuit 2 that its average level is within a certain level range, an original signal B outputted from the circuit 2 is divided by a signal A, which is obtained by processing the signal B in an LPF3, in a dividing circuit 4. The output from the circuit 4 is converted to a floating binary. Since S/N is raised effectively by this dividing processing, defect signals are accurately extracted without failures.

IPC: B41F7/26
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent an ink from being scattered from a water supply roller end. SOLUTION: A metering roller 10 has a body 11, and ends 12, 13. The body 11 is formed of Rilsan(R). And, the ends 12, 13 are formed of a stainless steel. Since the Rilsan is lipophilic, a dampening water of an emulsified state (dampening water mixed with an ink) is adhered to an outer periphery 11G of the body. However, since the stainless steel is hydrophilic and oleophobic, the ink of the emulsified state is not adhered to end outer peripheries 12G, 13G. Therefore, the emulsified ink stored at the end of the roller 10 is prevented from being scattered.
