Title: Picture processing method
Inventor: MIURA TAKANOBU
IPC: H04N5/225
Filed: 1988-12-28
Abstract: PURPOSE:To recognize shape and dimension in a short time even when the shape and dimension is changed by using a filter, on which surface a lattice- shape groove is worked. CONSTITUTION:Light irradiated from a light source 3 passes through a coiling window 2' of a member 2 to be image-picked up and reaches a filter 4. Since there is the lattice-shaped groove on the surface of the filter, the light transmits through a part excepting for the groove and is diffused in the part of the groove. Then, in a picture image-picked up through the lens system of a TV camera 1, two striations 6 and 7 appear orthogonally with a coiling window 5 as a center. Data for each line A,A' and B,B' in the longitudinal and lateral direction are detected for each picture element and by discriminating light and shade, the two striations 6 and 7 are detected. Further, by obtaining the central coordinates of the respective striations, the central position of the coiling window is detected. When coiling work proceeds, the coiling window 2' is gradually closed by a wire. However, when the picture data for one line are processed, the central coordinates of the brightest and widest striation, out of the plural striations, are obtained. Thus, the central position of the part, which is opened most widely, in the coiling window is obtained.

Title: Semiconductor memory
Inventor: MIYASHITA KOJI
IPC: G11C17/18
Filed: 1990-11-29
Abstract: PURPOSE:To accomplish low power consumption and to reduce a layout area in a bit line by precharging a data line and the bit line only by a data line load circuit. CONSTITUTION:In the case that logic 'L' is stored in an N type MOSFET (MHOS) 2-1 being a memory cell, a column selection transistor NMOS 5-1 is in an on-state when the word line 9 is in the state of the logic 'L'. At such a time, an NMOS 7 is activated by a control signal 3, and the data line 6 and the bit line 1-1 are simultaneously precharged to the logic 'H'. Next, when the word line 9 changes to the logic 'H', the NMOS 2-1 becomes in the on-state and the bit line 1-1 becomes the logic 'L'. When the NMOS 5-1 is in the on- state, at the same time, the data line 6 also becomes the logic 'L', which is outputted from an inverter 8. At this time, other column selection transistor is turned off and the bit lines 1-2 to 1-N are not precharged. Thus, the low power consumption is accomplished and the device is highly integrated.

Title: Memory circuit device
Inventor: TANIGUCHI MASAHARU
IPC: G06T1/60
Filed: 1989-12-20
Abstract: PURPOSE:To improve the reading efficiency of data from a memory by providing a circuit for detecting that all data for one line written in a line memory are 'H' or 'L' to the periphery of the memory. CONSTITUTION:The output D1 of an n-input NAND circuit 2a for inputting data to the line memory 1 goes the data input of the 1st FF 2c and outputted to an output Q1 by a clock, the inverse of WE. When all the input data for one line to the line memory 1 are 'H', the output D1 is always 'L' at the time of inputting the clock, the inverse of WE, and thereby the output Q1 also is always 'L', so that the output QC of the 2nd FF 2e is still held at 'H' even if the writing of the one line data in the memory 1 has been completed. When the input data to the memory 1 are not all 'H', the output QC of the 2nd FF 2e is turned to 'L'. Namely, when even one of the input data is 'L', the FF 2e latches the 'L'. When the output QC of the FF 2e is used as a flag for detecting all 'H', whether data to be read out are all 'H' or not can be detected at the time of reading out the data written in the memory 1.

Filed: 1993-12-27
Abstract: PURPOSE:To provide a reception circuit of a two-wire time division transmission system, which can detect a bit position except for the start bit of an equalized reception signal and can appropriately set the gain of an equalizer. CONSTITUTION:A peak holding circuit 50 holds the maximum level (e) of the equalized reception signal (c), which is outputted from the equalizer 10. A bit detection circuit 40 detects an initial bit position larger than a prescribed threshold for the prescribed number of times from the equalized reception signal in the same place. A level detection circuit 30 detects a bit level (d) in the bit position, which is detected by a bit detection circuit. An equalizer control circuit 20 receives the bit level (d) and the maximum level (e) and compare them with the prescribed threshold. When (e) is larger than the threshold, a control signal (b) for reducing the gain of the equalizer is outputted. When the threshold is smaller than (e), a control signal (a) for raising the gain of the equalizer by (d) is outputted. The equalizer 10 compensates the line loss of a transmission line. An identification circuit 60 converts the equalized reception signal into a digital signal.
