Title: Image forming element and its forming method
Inventor: AYLWARD PETER THOMAS
IPC: G03G5/10
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To obtain a base for forming an image reducing gloss and glare at the time of observing a print by making the surface roughness of a laminated base having a biaxially stretched film stuck to the uppermost surface of the base within a specified range. SOLUTION: This image forming element is provided with a laminated base having a biaxially stretched film layer stuck to the uppermost surface of the base and having average surface roughness of about 0.5-2.54 μm. Since a random surface pattern formed on the rough surface on the biaxially stretched sheet disperses reflected light in a random style especially useful in many photographic markets, it is preferable. The surface roughness of the biaxially stretched sheet can be formed by mixing a water-soluble binder resin or a solvent-soluble polymer binder with an inorganic pigment or a filler. As an additional method, desirable surface roughness can be attained by using a mutually insoluble block copolymer preferably, such as a mixture of polyethylene and polypropylene.

Title: Exposing unit
Inventor: MURANAKA YOSHIHARU
IPC: B41J2/44
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To obtain an easy-to-manufacture exposing unit in which the quantity of light being projected onto a photosensitive sheet can be increased by fixing a convex lens for focusing light projected from an LED arranged on a lower head case to the lower surface at the opening of an upper head case thereby suppressing diffusion of light and defining the focal point. SOLUTION: An LED 2 is arranged on the upper surface of a lower head case 1, an opening 4 is made in an upper head case 3 and a convex lens 5 for focusing light from the LED is fixed to the lower surface at the opening. Light is projected from the LED 2 toward the opening 4 and focused through the convex lens 5 in order to print onto a photosensitive sheet K placed on the upper head case 3. According to the arrangement, diffusion of the light projected from the LED 2 to the photosensitive sheet K is suppressed, the focal point can be defined and clear printing can be ensured by increasing the quantity of light being projected onto the photosensitive sheet K. Furthermore, the number of LEDs can be decreased and a head can be manufactured inexpensively while eliminating blur.

Title: Watch dog timer
Inventor: NOHARA NORIYOSHI
IPC: G07C3/00
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To solve such problem on the safety of a system when any unpredicted signal is outputted from the port of a microcomputer during a runaway and following reset. SOLUTION: An instruction decoder 3 decodes a watch dog timer initialization instruction to be cyclically executed, and generates an instruction pulse for initializing the number of counts of a counter 1. Then, a delay operation is operated based on the rising of the instruction pulse, and the obtained instruction pulse is outputted to a counter 1 as a single for initializing the number of counts. When operating frequencies are high frequencies, or a power supply voltage is a low voltage, any pulse signal is not outputted to the counter 1 by a delay circuit 2 so that a microcomputer can be reset by this watch dog timer.

Title: Control rod for reactor
Inventor: UEDA KIYOSHI
IPC: G21C7/113
Filed: 1990-12-11
Abstract: PURPOSE:To increase a mechanical life and to reduce an exchange frequency by a method wherein the covering pipe of a neutron absorption rod is formed approximately in a circle in cross section and a recessed part dented inwardly in an axial direction by a specified length is formed in a part of the peripheral wall thereof. CONSTITUTION:A neutron absorption rod 17 formed approximately in a circle in cross section contained in a sheath 16 is formed in such a way that at least a part of the section of a sheath pipe 18 thereof has an inwardly dented recessed part 20 so that a containing space for a neutron absorption material 19 is narrowed. When swelling is produced owing to irradiation of the absorption material 19 with neutrons, the inwardly deformed recessed part 20 of the covering pipe 18 is expanded outwardly to be formed in a circle. Since the recessed part is relatively easily deformed outwardly until it is formed in a complete circle, a generating period of a stress on the covering pipe 18 is sharply delayed. Thus, a mechanical life for the absorption rod 17 is increased by an amount equivalent to a delay in a stress generating period and an exchange frequency can be reduced.
