Title: Inspection apparatus
Inventor: KURIHARA HIROSHI
IPC: G01R31/00
Filed: 1984-10-01
Abstract: PURPOSE:To facilitate correspondence even if a control object is increased, by providing a plurality of decoder parts between the 8-bit parallel output pat and the drive of a control unit. CONSTITUTION:Because the control data in ROM 21d-1, 21d-2 addressed by the data of a control unit 21a are inputted to drivers 21c-1, 21c-2, even if there is an error in the unit 21a, the control data thereof is prevented from being stored in ROM 21d-1, 21d-2 to prevent the erroneous operation of the drivers due to erroneous data. Further, because ROM 21d-1, 21d-2 drive elements on the basis of the control data sent out from ROM 21d-1, 21d-2 by said addressing, it is unnecessary to increase the output port 21b of the unit 21a even if the number of elements are increased. Therefore, only ROMs or drivers may be increased and simple disposal is enabled.

Title: Press-through pack, and method for detecting absence of contents therefor
Inventor: NOJIRI YUZO
IPC: B65D75/34
Filed: 1994-08-06
Abstract: PURPOSE:To provide a press-through pack, for which detection of presence or absence of contents can be made by means of photoelectron switch. CONSTITUTION:A press-through pack is composed of a sheet-like metal foil container body and a sheet-like covering material. A number of pockets for housing contents individually are provided to the metal foil container body, and the covering material, and the covering material is laminated over the container body for sealing mouths of the pockets. The inside of the pocket of the container body and the surface of the contents are colored in different colors. Therefore, when visible radiation is shed to the inside of the pocket, reflection becomes such that corresponds to the color of the contents when the contents are present in the pockets while reflection becomes such that corresponds to the color of the inside of the pocket when the contents are absent in the pocket. Significant difference is present between both of the reflections. Thereby, presence or absence of the contents in the pockets can be discerned easily by means of a photoelectron switch.

When the reproducing information signal from the recording medium does not exist, that is, when the non-recording part of the tape is reproduced, the rotation speed of the rotating magnetic head 2 is calculated from the number of the rotations (or frequencies) of a rotation driving system (for example, reels 15 and 17) by the second servo system, and the rotation speed is controlled based on a calculated tape scanning speed. Thus, the head searching of the music in the high-speed search is assured.

Title: Picture data compressing device and picture data restoring device
Inventor: HONMA TOSHIMITSU
IPC: G06T9/00
Filed: 1993-07-27
Abstract: PURPOSE:To efficiently restore a picture with subjectively less deterioration by adopting a nonlinear quantization technique depending on a visual intensity characteristic. CONSTITUTION:Picture data are divided into blocks each comprising a picture element matrix of 8X8 (longitudinal X lateral) for each frame, subjected to the DCT processing by a transforming section 12 and DCT coefficient data of 8X8 are generated. A quantization section 13 quantizes each block of the coefficient data. A spatial frequency quantization table(SQT) and an intensity quantization data table(DQT) are used for the quantization. A 2-dimension matrix obtained by the quantization section 13 is subjected to zigzag scanning in a scanning section 14, and transformed into a one-dimensional vector. Furthermore, a coding section 15 applies run length coding and Huffman coding to the vector. As a result, since a nonlinear quantization technique depending on the visual intensity characteristic is provided by improving a linear quantization technique utilizing the spatial frequency characteristic of the vision, a picture with subjectively less deterioration is efficiently decoded.
