Title: Semiconductor nonvolatile memory device
Inventor: SEKI KOICHI
IPC: G11C17/00
Filed: 1986-01-29
Abstract: PURPOSE:To make the most of a high driving capacity and a minute signal detecting capacity of a bipolar transistor, and to execute read at a high speed, by constituting the titled device by containing the bipolar transistor in the peripheral circuit of a semiconductor nonvolatile memory. CONSTITUTION:In a reading-out circuit 6, a feedback circuit which has been constituted of a conventional MISFET, and a part of a transfer gate 18 are replaced with a bipolar transistor Q2 and a constant-voltage VBB. By storage information of a memory cell, a current of a bit line is varied, and this current variation (about scores of muA) is detected by a load resistance. Usually, a large floating capacity adheres to a nodal point C, but when this potential is suppressed so as to be constant by the bipolar transistor Q2, the current variation of the bit line becomes a variation of a collector current as it is, and a floating capacity of a point D of the collector side is small, therefore, even if an amplitude of 0.1-1V is fetched, the delay time can be shortened. At the time of the amplitude of the nodal point C is suppressed, even if gm of a memory cell transistor is small, the operation can be executed at a high speed. This output is connected to a differential amplifier consisting of Q4 and Q5, through Q3.

Title: Signal processing unit
Inventor: ARAI HIDEO
IPC: H04N19/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To realize the digital moving image compressor with high image quality and a small delay. SOLUTION: An interlace image signal is given to a compression unit configuration means 201 from a terminal 211, in which a compression unit in response to coding whether depending on a field structure or a frame structure is configured. In the case of the frame structure, a changeover means 214 switches a signal in the frame or field compression unit stored and configured in an image storage means 212 and gives to a macro block configuration means 215. In the case that the compression unit is fixed to a field structure, the changeover means 214 selects an interlace image signal from the input terminal 211 and gives directly the signal to the macro block configuration means 215. Thus, in this case, almost no delay is produced.  The macro block configuration means 215 rearranges information for each macro block and the result is outputted from a terminal 216, the information is compression-coded by a compression means and converted into a bit stream at a prescribed rate by a smoothing means.

Title: Halftone recording thermal head, method and apparatus for halftone recording
Inventor: ISHII TSUTOMU
IPC: H04N1/23
Filed: 1993-02-03
Abstract: PURPOSE:To eliminate the lowering of image quality due to the line formation in the main scanning direction in a sub-scanning direction dividing system. CONSTITUTION:The width (d) in a sub-scanning direction of each of the heating resistor elements 3 of a thermal head is made narrower than the width D of one pixel in the sub-scanning direction and the position or printing position in the sub-scanning direction of each of the heating resistor elements 3 is arbitrarily set within the width of one pixel. Therefore, the printing dots of the respective lines recorded by the respective heating resistor elements 3 are not continuously and linearly connected along a main scanning direction and the stripe like noise in a printing image caused by the line formation in the main scanning direction can be eliminated. Since the overlap of the respective colors of printing dots is arbitrary in color recording, the color shift of the whole of an image is not generated.

Abstract: PURPOSE:To reduce the generation of an error, while maintaining the detection resolution and to contrive the improvement of the detection accuracy by setting a sampling period of pulse output data to T/N (N is an integer of >=2) with respect to the counting time T. CONSTITUTION:First of all, an arithmetic unit 5 fetches the holding data C of a data latch circuit 4, and thereafter, executes a speed arithmetic operation by using the data C and a data group stored in a memory device 6. The memory device 6 stores successively sampled data by a 2n - piece portion (n denotes an integer) and in a storage area, data m(1), m(2), - m(2n - 1), and m(2n) are stored. Subsequently, for instance, an arithmetic operation by a 3-point difference method such as an expression {3*C - 4*m(n) +m(2n)}/4n is executed. Next, by storing 6 the latest data C and driving out the oldest storage data from the memory device 6, the storage contents of the memory device 6 are rewritten. In such a manner, the detection resolution of a speed is not varied and a time delay becomes 1/2n, and an error at the time of reading a speed calculated value can be reduced.
