Title: Liquid crystal display device
Inventor: SUZUKI KOJI
IPC: G09G3/36
Filed: 1990-07-25
Abstract: PURPOSE:To allow the extremely stable supply of video images to a data line or respective picture elements by using at least >=1 charge coupled devices (CCD) as means for generating a signal voltage for display. CONSTITUTION:A display signal Vin is divided to Vin1, Vin2 respectively by analog switch elements 104a, 104b of a high-speed type. These signals are lowered in signal band as compared with the input signal Vin. Two pieces of the switches 104a, 104b are merely required to be provided in a driving circuit, by which the element area is drastically decreased. The Vin1, Vin2 are respectively transferred through charge implanting circuits 105a, 150b to CCDs 1 and 2 and are successively sent. The respective CCDs operate at clocks phic and phi'c and may be shifted by as much as the phase difference component of the Vin1, Vin2. The number of stages of the respective CCDs may be half the total number of data lines 102. The charge quantity transferred in the CCDs is converted to a voltage value and is made into about 3V in peak value. The charges of the respective channels are simultaneously sent to a control circuit after the end of the charge transfer for one horizontal scanning component.

Title: Scan in/out logic circuit for lsi
Inventor: TSUCHIYA MASAKI
IPC: G06F11/22
Filed: 1989-07-26
Abstract: PURPOSE:To eliminate a need to provide the external circuit of an LSI with a special circuit and to reduce the cost of a circuit and to miniaturize it by providing a selector and a latch circuit, which latches the output of a flip flop. CONSTITUTION:When a scan mode signal is '0', an input A is selected in a selector SEL, and a normal condition is inputted to the D terminal of an FF and is set to the FF by the rise of a clock. Meanwhile, the output of the FF is outputted to a latch LAT as it is. At the time of next scan operation, the scan mode signal is changed from '0' to '1'. The latch LAT latches the state of the FF for the change of the scan mode signal from '0' to '1'. When scan-in data and the clock and supplied, the FF functions as a shift register and data is successively shifted to the FF in the next stage. At this time, the output of the latch LAT is not changed independently of the state of the FF. Since the output of the LSI is not changed in the scan mode, it is unnecessary to provide the external circuit of the LSI with a special circuit, and the cost is reduced and the circuit is miniaturized.

Title: Data transfer system
Inventor: OSAWA JIRO
IPC: H04L1/08
Filed: 1984-09-18
Abstract: PURPOSE:To improve the data transfer efficiency by informing the result of discrimination to the transmission side every reception after n times in a system which discriminates data as normal data when n times of coincidence (n<N) is obtained in the reception of same data for N times. CONSTITUTION:In the data transmission system where data is discriminated as normal data when the same data is received for, e.g., 5 times and the data is coincident for 3 times, when a reception circuit 1 completes the reception data D1-D3, they are stored sequentially in buffer memories 2-1-2-3. A discrimination circuit 30 collates mutually the content of the memories 2-1-2-3 and when all three data are coincident, the data D1 is discriminated as a normal reception data and the result of discrimination is informed to the transmission side via a transmission circuit 4. When the transmission side receives it, the repetitive transmission is stopped afterward. When the data D1-D3 are not coincident, the 4th data D4 is received and stored in a memory 2-4. The circuit 30 collates the content of the memory 2-4 with that of the 2-1-2-3, and when they are coincident, the result is discriminated a normal data and the result is informed to the transmission side via the circuit 4. When all the three data are not coincident, the next 5th data is collated.

IPC: H01L21/3065
Filed: 1985-09-03
Abstract: PURPOSE:To reduce cracks or improper insulators near the edge of a coating film formed on a thin film pattern by selectively rounding only the edges of the pattern by etching. CONSTITUTION:When a conductor pattern 2 is formed on a substrate 1, an abrupt edge 9 frequently remains on the periphery of the pattern. When a photoresist 3 is coated on the entire substrate which contains the pattern 2, the vicinity of the edge 9 is thinnest as compared with the other flat portion of the photoresist 3. Then, when ion milling at 4, the photoresist 3 is uniformly etched from the surface. Here, when the photoresist 3 near the edge 9 finishes etching, the edge 9 of the pattern 2 simultaneously starts being etched. When the photoresist 3 remaining after selectively etching the edge 9 is removed, a conductor pattern 2' having a rounded edge is formed, and an insulating film 5 is then laminated on the entirety.
