Title: Video signal processing circuit
Inventor: MURAKAMI TOSHIO
IPC: H04N5/20
Filed: 1985-12-28
Abstract: PURPOSE:To obtain necessary knee slopes equally from knee slopes for every knee point by changing the knee point of a white knee circuit and changing the knee point in accordance with the level of an input signal. CONSTITUTION:At a comparator 4, the control of a knee point is started by the direct current voltage or above in which an inputted clamping video signal is determined by the sliding position of a variable resistor 5. The output of the comparator 4 is inputted and inverted to a phase inverter 6. A variable resistance 9 mixes the inverting signal and the normal rotating signal of the comparator 4. The mixing ratio is determined by the sliding position of the variable resistor 9. The output of the variable resistor 9 is inputted from a control input terminal 8 to a white knee circuit 7 as a control signal, responds to the voltage and the knee point is changed. When the input level is changed to V1, V2, V3 and V4, n1, n2, n3 and n4 and knee points are changed, the knee slope becomes smooth and the effective scope of the input level is extended.

IPC: H01J9/227
Filed: 1994-11-29
Abstract: PURPOSE: To decrease generation of the shadow to be generated by the effect of boundary steps between mutually adjacent lens blocks by making one side of the boundary part of a single lens block adjacent to two or more lens blocks. CONSTITUTION: The boundary lines between lens blocks 50a of a lens block 50 are deviated by the distance of a half of one side of the single block 50a every one line. By this structure, the lattice-like shadow to be formed on the irradiated surface is made discontinuous by shading by step parts 50b of,the boundary parts of the lens blocks 50a in exposing. Since the boundary surface including the step parts 50b of the boundary parts between the lens blocks 50a are formed along the incident light, the step parts 50b of the lens blocks 50a on the periphery of a multi-lens are diagonally formed along the indecent light. Therefore, generation of the shadow to be generated by the effect of the boundary steps between the mutually adjacent lens blocks 50a can be decreased.

Title: Ringing signal detecting system
Inventor: TANAKA KAZUO
IPC: H04M3/02
Filed: 1989-11-14
Abstract: PURPOSE:To reduce the number of hardwares and to accurately detect and transfer a ringing signal by shaping the waveform of a pulse by a software in a control part and correcting the distortion of the shaped waveform to a pulse width equal to the holding period of a rectangular wave. CONSTITUTION:A rectangular wave output from a ringing signal detection part 21a is directly outputted to a processor, i.e., a control part 29. The control part 29 executes the waveform shaping 29a of the rectangular wave to the pulse of a pulse width longer than the holding period of a rectangular wave consisting of plural waves and then the shaped waveform is distortion-corrected 29b to a pulse width equal to the holding period of the rectangular wave as a ringing signal detecting output (8). Namely, a detection part output (2) being a signal with an unstable detection level is directly sent to the control part 29 and stabilized by the software in the control part 29. Consequently, waveform shaping based on the hardware can be omitted, the circuit can be simplified and the cost can be reduced. In addition, an accurate ringing signal can be detected and transferred by distortion correction or the like.

Title: Non-volatile semiconductor memory circuit
Inventor: KATO HIDEO
IPC: G11C29/24
Filed: 1992-11-05
Abstract: PURPOSE:To detect and erase the memory cell of an overerasing state by detecting the potential change of column lines by conduction by a differential amplifier as the cell of the overerasing state is depressed and is, therefore, conducted if there is such cell at the time of a test mode. CONSTITUTION:A row decoder 23 puts all column lines WL 1 to m in a non- selection state, i.e., at a ground level. A source VSS* is at the ground level. The column lines BL 1 to n are successively changed over and selected by a column decoder 22 in this state and the data from a sense amplifier(SA) of this time is read out. The overerasing state memory cell(OEMC) is then detected. Namely, the threshold voltage of the OEMC is negative and is depressed if the OEMC exists in the selected column line and, therefore, leak current flows to the column line. Then, the column lines BL 1 to n are originally charged and the output via an output circuit 24 from the SA is ought to be 0 but is 1 because of the leak current. As a result, the OEMC is detected and erased.
