Title: Preset channel selector
Inventor: SUZUKI TATSU
IPC: H03J7/18
Filed: 1978-07-20
Abstract: PURPOSE: To obtain an economical and easy-to-use preset channel selector, by preventing the presetting of the same station by making it possible to know whether a station in reception is preset or not.  
     CONSTITUTION: With switch 50 ON, FF51 is set to make its output high in level, and consequently a clock pulse is applied to the up input of up-down counter 47 via gate 48, thereby varying the division ratio of variable divider 21. If a receiving station exists when the content of counter 47 reaches a certain value, a signal appearing at the output of intermediate frequency amplifier circuit 17 resets FF51 to  make its output low in level and any pulse is not applied to counter 47 via gate 48.  When the content of counter 47 has been written to memory 42 yet at this time,  light emitting element 57 comes on and when not, it stays unlighten. In this way, it  is made possible to make a comparison between a tuning frequency stored in memory 42 and that obtained through the operation.

Title: Programmable logic array
Inventor: MAYUMI HIROSHI
IPC: H03K19/177
Filed: 1979-07-13
Abstract: PURPOSE:To ensure the nondefectiveness in application of the programmable logic array as a whole even though some defect may exist, by providing the spare product term row. CONSTITUTION:In the product/sum-type field programmable logic array FPLA, the defective product term is ''killed'' to have no function by utilizing the fact that the function has no change even if the product term row may be replaced optionally and by providing previously spare product term row. In other words, a low level is given to the wiring of the product term row at the side of the product array. Programmable element C forms product array 10 (four product terms A1-A4 plus intersection between I1'/I1'' and I2'/I2'') as well as sum array 20 (A1-A4 plus intersections of outputs O1-O4). And in case some defect exists at the element of product term A1, the programming is first given to both elements on the line of the proper positive auxiliary inputs (such as I1' and I1'') among the normal elements at the product array side on product term A'. Thus those two elements are turned on. As a result, term A' is always set at a low level regardless of the input and gives no drive to the side of the sum array. In other words, the ''killing'' is carried out.

Abstract: PURPOSE:To enable a sharp image with a multiple of gradations to be formed by forming a density gradation by use of a difference in the sensitivity of a photoconductor to plural kinds of light rays of different wavelengths. CONSTITUTION:Two kinds or more of light rays of different wavelengths are applied to a photoconductor to form an image having gradations in optical density; i.e., the photoconductor with the spectral sensitivity shown in the figure is used, and when three kinds of light rays of wavelengths lambdaa, lambdab, lambdac are applied to different portions of the photoconductor, for example, the portion to which the light ray of wavelength lambdaa is applied has the highest density, and the optical density decreases from the portion to which the light ray of wavelength lambdab is applied to the portion to which the light ray of wavelength lambdac is applied. Thus an image with a multiple of gradations can be formed by use of the difference in optical density. Preferably, two kinds or more of light rays to which the photoconductor has sensitivity should not be applied to the same portion of the photoconductor.
