Title: Semiconductor memory circuit
Inventor: SATO NORIAKI
IPC: G11C17/14
Filed: 1989-02-08
Abstract: A semiconductor memory circuit comprises a plu­rality of memory cells (M11 - M22) and a plurality of programming transistors (1), each memory cell being provided at the intersections of one bit line (BL1 - BL3) and one word line (WL1 - WL3). The memory cell includes an insulator (2) and a cell transistor (3), and a conductivity type of the cell transistor selected by a word line select signal is opposite to that of the programming transistor selected by a bit line select signal (Vin). The memory cell is programmed by utilizing an electrical breakdown of the insulator, when the bit line select signal and the word line select signal supplied are in-phase and both the programming transistor and the cell transistor are switched. Therefore, the memory cell is programmed in a short time during which the programming transistor and the cell transistor are switched, and thus this semiconductor memory circuit can be programmed with a low consumption of power and of a high speed.

Abstract: A method for preparing a vaccine for dental caries comprises the step of culturing a variant which is obtained by integrating a protein antigen (PAc)-expressing gene into the chromosomal gene of a Streptococcus mutans GS-5 strain to obtain the protein antigen, the protein antigen being produced on the surface of cells of oral Streptococcus mutans or it being extracellularly produced by the microorganism and having a molecular weight ranging from about 170,000 to 220,000. Streptococcus mutans GS-5 (K-3), in which a protein antigen-expressing gene is integrated into the chromosomal gene thereof, has an ability of producing the protein antigen on the surface of the cells or extracellularly. A preventive vaccine composition for dental caries for nasal drops comprises the protein antigen thus produced by the strain: Streptcoccus mutans, the vaccine being intranasally administered. The method makes it possible to enhance the yield of PAc and to simplify processes for purifying PAc. The vaccine composition makes it possible to internally easily absorb the protein antigen, PAc, in high efficiency and it also makes it possible to effectively increase the antibody titer observed after the administration thereof. 1

Abstract: A moving target detector (MTD) (23) in a pulse radar system (10) uses corrected weighting coefficients (W i ) to compensate for pulse stagger effect on transmitted pulses. Transmitted pulses are sampled (15, 17, 19, 20) when the radar is switched (32) to a test mode for determining a correction factor which is used to calculate (31) the corrected weighting coefficients (W i ) The radar return signals received through the antenna (18), duplexer (16), coupler (20), receiver (21) and quadrature detector (22) are processed in the MTD (23) by a finite impulse response (FIR) filter (24) using the stored (26) corrected weighting coefficients (W i ) calculated (31) for each sequence of transmitted pulses including block stagger and pulse stagger sequences. 
     In the test mode, pulses from the transmitter (14) are routed from a coupler (15) by an operate/test mode controller (32) through a delay (17), attenuator (19) and the coupler (20) to the receiver (21), and from the quadrature detector (22) to the coefficient calculator (31) which also receives uncorrected coefficients D i . In the operate mode, the appropriate corrected coefficient (W i ) is selected from a memory (26) by a synchronizer (28) that triggers the transmitter (14).

Abstract: A display system is described that allows the rapid display of colour images on screen, and removes the need for extensive image pre-processing prior to display on screen. A universal palette is utilised, divided into several sub-palettes, each one containing data pertaining to shades of different, individual colours. For example, in a palette with an 8 bit address, 64 shades each of red, green, blue and grey could be stored. Source colour data are supplied to logic which selects a particular colour component's data, and this data is then utilised to address the sub-palette containing data pertaining to shades of that particular colour. For example, red source data are utilised to address the section of the palette (sub-palette), containing data yielding red colour shades. Pixels are grouped on screen to form a macro-pixel, each pixel of the macro-pixel being devoted to one particular colour shade. The eye then acts to merge these colour pixels on screen to form the composite colour of the macro-pixel. In an alternative embodiment, all of the source colour data are used to address the palette. Overall contouring of the image on screen is removed without the need for extensive image pre-processing, thus allowing the rapid display of guality images on screen.

Abstract: A system and method for maintaining focus of a laser beam (18) on the surface of an erasable magneto-­optic disk (12) during erase operations is disclosed. The laser beam (18) exhibits beam farfield shift during erase operations, complicating the maintenance of optimal focus. An optical detector is exposed to laser light (18) reflected to the disk (12) to generate signals governing operation of a focusing lens' servo system. A digital signal processor (34) is included in the servo system and is programmed to compensate for beam farfield shift by generation of an offset correction signal during periods of erase power operation. The offset correction signal is generated by the digital signal processor (34) by comparison of optical detector output signals generated during operation of the laser source (13) where no beam farfield shift occurs and the output signals generated where beam farfield shift is occurring, but the system is known to be in focus.

Abstract: In a speech encoder, high-frequency components of input digital speech samples are emphasized by a preemphasis filter (11). From the preemphasized samples a spectral parameter (a;) is derived at frame intervals. The input digital samples are weighted by a weighting filter (13) according to a characteristic that is inverse to the characteristic of the preemphasis filter (11) and is a function of the spectral parameter (a i ). A codebook (18, 19) is searched for an optimum fricative value in response to a pitch parameter that is derived by an adaptive codebook (16) from a previous fricative value (v(n)) and a difference between the weighted speech samples and synthesized speech samples which are, in turn, derived from past pitch parameters and optimum fricative values, whereby the difference is reduced to a minimum. Index signals representing the spectral parameter, pitch parameter and optimum fricative value are multiplexed into a single data stream.
