Abstract: A sorting and conveying line provided at an X-ray film cutting and collection operation includes a defective sheet gate, a collection gate and a sample gate for sorting X-ray film sheets, which have been cut to a predetermined size at a cutting section, while the X-ray film sheets are conveyed. Film detection sensors are disposed at entrance and exit sides of each of the defective sheet gate, the collection gate and the sample gate, and each film detection sensor detects the X-ray film sheet at times when the X-ray film sheet should be conveyed and sorted. Based on the results of detection, a determination is made as to whether or not there is any failure in control on a number of produced X-ray film sheets, and the like, as well as conveyance and sorting operations. This allows smooth and quick handling in the event of a failure.

Abstract: A sheet package producing system includes at least a cutter module and a packaging module. The cutter module has a cutter blade, for producing X-ray films by cutting a continuous sheet material. The packaging module has packaging robots, for producing a sheet package by packaging the X-ray films stacked on one another. In the sheet package producing system, a first module control unit is incorporated in the cutter module, for controlling the cutter blade. A second module control unit is incorporated in the packaging module, for controlling the packaging robots. A CPU is connected with the first and second module control units removably by a component network, for controlling the cutter module and the packaging module in synchronism.

Abstract: Illuminating light emitted from a light source is led via a condenser lens, an optical fiber, a half-silvered mirror, and a condenser lens to a reflector. The reflector reflects the illuminating light to a CCD device through a telecentric optical system which comprises the condenser lens, the half-silvered mirror, and an aperture member. The illuminating light applied to the CCD device is greatly reduced in amount as it passes through a light-transmissive sheet-like body twice. The light-transmissive sheet-like body itself or an edge thereof can be detected with high accuracy even if the light-transmissive sheet-like body has a high transmittance.

Abstract: A production management computer indicate the number of parts corresponding to a number of products smaller than a planned number of products to be produced to a controller. A parts supplying section supplies the indicated number of parts through a parts holding section to a product producing section. When the number of parts held by the parts holding section becomes nil, semi-products held by a semi-product holding section are counted, and as many parts as the number of the counted number of semi-products are additionally supplied. The product producing section can produce products without causing an excess or shortage of parts.

Abstract: A digital demodulator compensates for frequency offset between modulated and unmodulated carrier signals by detecting the frequency offset during a preamble with a known modulation pattern. Samples obtained during the preamble are stored in a memory during clock recovery, and read from the memory after the recovered clock signal has become stable. Phase offset is detected from a histogram of the phase differences between the two carrier signals, calculated modulo a certain phase angle, and compensation for phase offset is applied. The maximum histogram value is found by comparisons made according to a single-elimination tournament plan. In a diversity receiver, the maximum histogram value is used to select the output data.
