Title: Optical recording and reproducing device
Inventor: ISHIDA TAKASHI
IPC: G11B7/0045
Filed: 1987-07-27
Abstract: PURPOSE:To prevent a valuable data to be stored, from being broken down, by providing a comparator for deciding whether an address which is read out of an optical disk is within a set range or not to set a recording inhibited area. CONSTITUTION:When an address value C inputted to a comparator 11 from an address reading circuit 10 is smaller than a set value A or larger than a set value B, the output of the comparator goes to 'H', and by an AND circuit 12, a recording command signal J is inputted as it is to a laser driving circuit 13, therefore, a laser 2 emits a light beam by recording power and a data is recorded. When the address value C is above the set value A and below B, the output of the comparator goes to 'L', and even if the recording command signal J is inputted by mistake, since the input to a terminal 131 of the laser driving circuit 13 remains 'L' by the AND circuit 12, the recording power is not generated. In such a way, the breakdown of a valuable data caused by erroneous recording can be prevented.

Title: Production of substrate for information recording
Inventor: TODO AKIRA
IPC: B29C65/08
Filed: 1987-07-27
Abstract: PURPOSE:To prevent the generation of the positional deviation and warpage of spacers by ultrasonically welding an outside circumferential spacer to a disk substrate on one side and subjecting the outside circumferential spacer and the other disk substrate as well as the inside circumferential spacer and the disk substrates on both sides to simultaneous ultrasonic welding. CONSTITUTION:The outside circumferential spacer 5 and the disk substrate 3a on one side are first superposed on each other and are welded by the ultrasonic welding. The disk substrate 3a welded with the spacer 5 and the disk substrate 3b on the opposite side are then superposed on each other via the inside circumferential spacer 6 and the disk substrate 3b on the side opposite to the spacer 5 as well as the inside circumferential spacer 6 and the disk substrates 3a, 3b on both sides are simultaneously welded and stuck from one direction. Since the outside circumferential spacer liable to deviate in position is welded to the disk substrate on one side in the 1st stage, the positioning is facilitated. Since the unwelded parts are welded at one time in the state of welding the outside circumferential spacer to the one disk substrate, the residual strains are decreased. The generation of the positional deviation and warpage is thereby prevented.

Title: Fuel assembly
Inventor: SAKURADA KOICHI
IPC: G21C3/30
Filed: 1987-07-27
Abstract: PURPOSE:To improve reactor stop margin capable of responding to the high combustibility by arranging bundled fuel rods so that the center distance between the neighboring fuel rods belonging to different small units is larger than the distance between the center of the neighboring fuel rods in small units. CONSTITUTION:A fuel assembly 11 is formed of small units 13 of three columns and three rows by fuel rods 12, and eight sets of the small units 13 are incorporated in a square channel box. As compared with the fuel assembly 1 in which the fuel rods 3 are arranged at intervals of P0, the center distance P1 and P2 of the fuel rods 12 are larger than Pc, P0 is smaller than Pc, the ratio of the distance between the small units and the neighboring small units 13 W1 or W2 to thermal neutron diffusion length are enlarged. The smaller the density of water, the larger the thermal neutron diffusion length is, and the larger the density of water, the smaller the thermal neutron diffusion length is and so the lowering rate of thermal neutron utilization factor is small during operation and large at the time of cool temperature and stop. Therefore, during operation the effective multiplication constant of the reactor core is heightened and profitability is improved, and at the time of the cool temperature and the stop the effective multiplication is lowered and reactor stop margin can be increased.

Title: Ic card reader/writer
Inventor: ONO REIJI
IPC: G06K17/00
Filed: 1986-08-13
Abstract: PURPOSE:To prevent destruction due to a latch-up phenomenon by outputting a signal to an IC card only when a control means detects a supply current and forcibly ejecting the IC card if the supply current is not detected. CONSTITUTION:When the IC card is inserted, an IC card reader/writer 1 carries the IC card to a collect electrode position, and depresses a collect electrode to be conducted. A current conducted from a power source 3 is conducted to comparator 7 through resistances 5 and 6, where the supply current to the IC card is detected. If said current is not detected, namely, if a current is not conducted to the IC card normally and the signal is outputted in such a state, a signal voltage becomes higher that a power source voltage conducting to the IC card 2. If the latch-up phenomenon is occurred, the IC card 2 is forcibly ejected. Since the IC card 2 is forcibly ejected in case of conducting no supply current IC chips can be prevented from destruction due to the latch-up phenomenon.
