Title: Semiconductor memory storage
Inventor: MIYAKE SHINICHI
IPC: H01L21/8246
Filed: 1980-11-26
Abstract: PURPOSE:To improve charging property at the time of the reading of an ROM device, and to prevent malfunction by connecting junction capacity consisting of diffusion layers to the nodes of an IGFET for load and a plurality of FETs for switching connected in series. CONSTITUTION:Lines are formed by connecting the FETs1 for load and a plurality of the FETs2 for switching in series, the gate electrodes of the FETs of each line are connected to row lines A-F consisting of a plurality of conductive layers, and the matrix-shaped ROM device is formed. The drain diffusion layers 6 of the FETs1 functioning as the nodes of the FETs1 for load and the FETs2 and the output reading points 7 of the ROM are shaped so as to be extended and arranged among each line, and the junction capacity of the diffusion layers 6 are made larger than the parasitic capacity of the source-drain diffusion layers 5 of the FETs2 by approximately double. Accordingly, when the FETs2 are switched and read, parasitic capacity can rapidly be charged, and malfunction can be prevented. The device can be improved without increasing its space occupancy because the FETs1 require originally large areas.

Filed: 1993-06-14
Abstract: PURPOSE:To drive an intermediate size panel using an analog driver having a comparatively low sampling speed by sorting video signals by one line inputted time sequentially, lowering transfer speed of one pixel, and inputting them to plural analog drivers. CONSTITUTION:Video signals outputted from CCD shift register A and B are inputted to an analog driver 3 consisting of a sample-and-hold circuit and a driving circuit.

Title: Monitor signal measurement method for catv amplifier and catv amplifier capable of measuring the signal
Inventor: KURIHARA MASAMI
IPC: H04N7/16
Filed: 1994-06-28
Abstract: PURPOSE:To grasp dispersion in level deviations or levels while directly observing it on a spectrum analyzer by measuring a monitor signal for a CATV amplifier through a pseudo-transmission network built in the amplifier or mounted externally. CONSTITUTION:A broadcast signal sent from a center is received by an amplifier 1, which amplifies the input signal and the amplified signal is uniformly attenuated by an ATT independently of frequencies and the resulting signal is outputted to an output side monitor terminal 5. In the case of the measurement, a pseudo-transmission network 2 having an entirely reverse frequency characteristic to that of a desired monitor signal is connected to the monitor terminal 5 of the amplifier 1 and a spectrum analyzer 3 is connected to the transmission network 2. Although more or less high low differences are in existence on peak lines of a frequency spectrum displayed on a CRT of the spectrum analyzer 3, the difference represents a level deviation in the signal. Moreover, the amplifier 1 is adjusted in a way that the difference on the peak lines of the frequency spectrum is eliminated.

Title: Endoscope image pickup device
Inventor: YABE HISAO
IPC: G02B23/26
Filed: 1984-08-13
Abstract: PURPOSE:To photograph an image of a correct brightness extending over the whole picture irrespective of a focal distance by bringing an image signal of one picture to gain adjustment at every picture element in accordance with a focal distance of the time of an image pickup. CONSTITUTION:In case a focus point is 10-100mm. being the farthest, a lens 20 of an endoscope 10 is separated from an object to be photographed, therefore, it is unnecessary to compensate an intensity distribution of an illuminating light. In case the focus point is a middle distance (5-12mm.), a gain pattern whose gain is + or -0% in the center part and increases by +10% and +20% toward the peripheral part is generated from a gain pattern generator 44, and a luminance drop of an image of the peripheral part is corrected through a gain correcting circuit 36. Also, in case the focus point is set to a short distance, a gain pattern for compensating an influence exerted on an image luminance of an illuminating window 16 is generated from a gain pattern generator 44, and a gain correction 36 is executed. Accordingly, an image of a correct brightness is obtained irrespective of a focal distance.
