IPC: G06F3/05
Filed: 1986-02-18
Abstract: PURPOSE:To store a signal denoting a comparatively quick phenomenon at random with a comparatively simple constitution by providing a means controlling the selection action of a multiplexer based on data stored in an rewritable memory. CONSTITUTION:The analog signal with four channels are selectively added to an A/D converter through the multiplexer MPX to convert into digital signals, which are sequentially stored in a digital memory MEM. In that case, selection sequence data for MPXs is previously stored in a control memory CM from an external device EXT2. In order to store the digital signals converted by the A/D converter in the MEM, a control signal to synchronize with a reference clock signal is added for accessing to a CM from a CM control circuit CMCTL. In the process to store the digital signals converted by the A/D converter, there is not software, and quick processing can be executed accordingly.

Title: Back rest frame structure for vehicle
Inventor: WAKAO TOSHIAKI
IPC: A47C7/40
Filed: 1995-02-22
Abstract: PURPOSE: To enhance productivity while retaining sufficient stiffness in the manufacture of back rest frame structures for vehicles. CONSTITUTION: In a back rest frame structure 18, trapezoidal protrusions 38 and recesses 42 are formed facing each other on both edges of an approximately circular, closed cross section at the top section 28, and the protrusions 38 and recesses 42 are caused to engage each other. Because the protrusions 38 protrude into the cross section, the closed cross section does not open even during the collapsing process. This enhances productivity with sufficient stiffness retained. Bent sections 40 are formed by bending the ends of the protrusions 38 toward the bottom side of the recesses 42, which further increases the cross section coefficient and the strength and stiffness of the back rest frame 18.

Title: Aberration variable lens
Inventor: OKANO YUKIO
IPC: G02B27/00
Filed: 1980-03-17
Abstract: PURPOSE: To change spherical aberration without giving any fluctuation to other aberrations by changing the incident height of rays to the lens face on the image side through elongation or contraction of the air spacing between lenses.  
     CONSTITUTION: The lens system is divided to A group and B group by a variable air spacing dBO. The air spacing dBO is sandwiched by the two faces whose concave faces are directed to the position where full-aperture main rays intersect with the optical axis.

Title: Lighting device
Inventor: HAMADA HIROSHI
IPC: H04N1/04
Filed: 1985-02-22
Abstract: PURPOSE:To obtain a bright display with a high coefficient of utilization of light and without an unevenness of lighting by setting a definite ratio between the apparent space of every belt-shaped reflecting surface adjacent to each other and the apparent width of them. CONSTITUTION:Light that is outputted from a tube-shaped light source 1 is reflected in the direction of a prescribed visual angle by the belt-shaped reflecting surface 20A. A surface that is shown by a mark 20B is set as nearly in parallel with the light from the light source 1 or as to be the shadow of the belt-shaped reflecting surface 20A and is not bright when it is observed from the prescribed direction. Assuming that each width in the horizontal direction of each surface of 20A and 20B is set as (a) and (b), the luminance of the belt-shaped reflecting surface 20A is definite in spite of a distance from the light source 1 and the luminance when the stripes of light and shade is averaged becomes the multiply by a/(a+b) of the belt-shaped reflecting surface 20A. The smaller the (b), the higher the average luminance but the thickness (t) of a light guide 20 increases. The greater the (b), the lower the average luminance but the thickness (t) becomes thin and therefore, it is enough to change the ratio between (a) and (b) according to a requested means.

Title: Video display method
Inventor: MUROFUSHI TAKESHI
IPC: G01S7/298
Filed: 1985-02-26
Abstract: PURPOSE:To display the raster scan of signals obtained from PPI polar coordinate indication without non-uniformities in brightness by performing smoothing only for necessary periods as the function of brightness changes of adjacent display points. CONSTITUTION:Dot brightness signals A from a scan converter 60 and delayed dot brightness signals B through a latch 41 of a smoothing control part 40 are compared to each other. If the adjacent dots are different in the brightness, a comparator 42 outputs '1' to control a selector 53 through a shift register 43 and an OR circuit 48. The selector 43 selects smoothed data from a data converter 30 to effect smoothing for the dot period. Similarly, the output of an AND gate 50 is turned to '1' by a signal that needs to be smoothed in accordance with the 3-dot brightness pattern so that the smoothing is effected during the 3-dot period. When the change in the brightness is higher than a prescribed value, the smoothing is carried out for a prescribed period so that raster display of the PPI polar coordinate is performed without the brightness non-uniformities due to the smoothing.
