摘要:
There is provided a measuring board, in which an I/O switch is formed in the vicinity of an I/O terminal on the board and no deformation occurs in the wave form of an input signal. In the vicinity of the I/O terminal on the measuring board, on which a device to be measured (DUT) is mounted and in which testing is performed for the I/O terminal, there are provided a plurality of optically driven switches, each of which is composed of a photoconductive switch having electrodes with an electrode gap of a specified width on a semi-insulating semiconductor substrate and a semiconductor laser provided so as to irradiate the electrode gap. By these optically driven switches, input and output switching is performed for the I/O terminal.
摘要:
A host sends each page of image data to a page printer in band units and the page printer writes the received each band data into a reception buffer in DRAM by DMA and transfers the band data from the reception buffer to an image formation section made up of members. The host gets an available buffer capacity from the printer just before transmitting each band data, and transmits the band data only when the printer can receive the band data. In the printer, a CPU permits transfer DMA to be started after reception data as much as the data amount calculated based on the data reception speed and the transfer rate is stored in the buffer to prevent an underrun error from occurring. If an underrun error occurs, the CPU sets an error flag, and sends the error flag to the host just before the host starts transmitting each band data. When receiving the error flag, the host drops image resolution and resends the page data with the resolution dropped.

Accidents such as mistakenly delivering products belonging to a different buyer to the wrong person can be prevented. A receipt and claim ticket printing device that issues to a buyer of a product a receipt showing the product name and price and the total purchase amount, and a claim ticket for the product purchased by the buyer, has a product image storage unit that stores product images of the products that are sold; a product image extraction unit that extracts the product image of at least one of the purchased products from the product image storage unit when the receipt is issued; and a print unit that prints the claim ticket on which the extracted product image is printed with the receipt.
摘要:
A magnetic field measurement system including a pick-up coil is not moved but fixed. Strips of superconducting material are arranged in a plane with narrow slits between the strips. The strips are moved very near the pick-up coil along the plane. From output variations of a SQUID magnetometer during the movement, a magnitude of a static field perpendicular to the plane of the strips is obtained.
