摘要:
A data processing apparatus for an electronic cash register comprises a keyboard having a plurality of entry keys, a printer, a memory unit, an interface circuit with which a memory pack storing sales data is mechanically, electrically and removably coupled and a data processing unit connected with the keyboard, the printer, the memory unit and the interface circuit. Responding to operations of one of the keys for sales data selection, the data processing unit energizes the memory pack connected to the interface circuit to read out the sales data corresponding to the operated sales information key from the energized memory pack and write the read-out sales data into the memory unit and then issue a print signal to the printer for printing the sales data.

A memory pack is provided having a random access memory connected between a positive power source terminal and a ground terminal, an addressing terminal coupled with the random access memory, and a data input/output terminal coupled with the random access memory. The memory pack further includes an LED energizing terminal, a light emission element which is connected between the LED energizing terminal and a positive power source terminal, the LED being lit by an energizing signal applied to the LED energizing terminal, a RAM energizing terminal and a photocoupler which is connected between the RAM energizing terminal and the random access memory and which responds to an energizing signal applied to the RAM energizing terminal to apply an output signal to the random access memory thereby to set the random access memory to be operative.

A print control system managing a print job on a job basis and on a page basis. When a print job is interpreted, a job description file and page data for each page are created. The job description file contains the attribute of the entire job and a job element (content) list. An item of page data is associated with the print attribute of each page including image data. The job control module extracts necessary image data according to the job element list and sends it to a printer. Because a plurality of print jobs share the common data, many job management functions, including print job combination and page addition/deletion, can be implemented easily.

Electric discharge breakdown in an optical waveguide pattern formed on a crystal substrate having pyroelectric effect is substantially extinguished or reduced, so that the yield of optical waveguide devices in the manufacturing process can be increased. A plurality of optical waveguide patterns 5 are formed, in parallel, by means of heat treatment on a substrate 2 of lithium niobate having pyroelectric effect, and the formed waveguide patterns are cut into a predetermined chip-shape. In the manufacturing method of this optical waveguide device, patterns are formed so that both ends of the optical waveguide pattern 5 are respectively communicated at a position where both ends of the optical waveguide pattern 5 are out of an effective chip range. Further, a dummy pattern 26 is formed at a position close to a waveguide pattern 25.

A fuel assembly comprises a plurality of fuel rods bundled in grid pattern, a part of the fuel rods containing gadolinium as a burnable poison. At least one of the fuel rod having gadolinium contains gadolinium enriched in at least one kind of isotope of odd mass number more than an isotopic abundance of natural gadolinium. In the enriched gadolinium, a ratio of a content of Gd-155 to that of Gd-157 is 0.1 or less. An average concentration (wt %) G0 of enriched gadolinia is, with M denoting the number of month under rated power operation per one cycle of an equilibrium core, P power density of a nuclear reactor (kw/l unit) and W a sum of isotopic composition, is set in the range shown by the following expression.

Provided is a composition for a lightweight heat-insulating material having high heat-insulating properties. The composition for a heat-insulating material contains a fibrous material, inorganic foamed particles, a thermosetting resin, and a foaming agent. Since the composition for a heat-insulating material contains the inorganic foamed particles and the foaming agent in addition to the fibrous material and the thermosetting resin, the weight can be reduced and the thermal conductivity can be lowered due to the inorganic foamed particles having low specific gravity. Further, the thermosetting resin is caused to foam by the foaming agent, and the weight can be reduced and the thermal conductivity can be lowered. A lightweight heat-insulating material having high-insulating properties can be obtained.
