Title: Method for forming multicolor image and device therefor
Inventor: HASENAMI SHIGEHIKO
IPC: G03G15/01
Filed: 1994-08-04
Abstract: PURPOSE:To prevent the lowering of reliability caused by a reelectrifying stage in one cycle of forming a multicolor image, to effectively avoid color mixing with a toner image, and to avoid the deterioration of image quality based on environmental change or use histroy if necessary. CONSTITUTION:A latent image forming stage B is performed to a latent image carrier 1 electrified in a uniform electrifying stage A so as to form plural latent images Z1, Z2... whose maximum exposure levels become smaller and smaller successively. After the 1st latent image Z1 is visualized with 1st color toner T1 in a 1st developing stage C, uniform exposure is performed in a uniform exposure stage D by using light of wavelength whose transmissivity to the 1st color toner T1 is low so that the absolute value of the potential of a non- image part may be higher than that of the potential of a toner layer in the lst developing stage C. Thereafter, the 2nd latent image Z2 is visualized with 2nd color toner T2 in a 2nd developing stage E. Then, the same stages are repeated to form the multicolor image. The condition of the potential on the latent image carrier 1 is controlled by detecting the potential of the latent image carrier when necessary.

Title: Thermal cell
Inventor: YAMAZAKI HIROSUKE
IPC: H01M6/36
Filed: 1983-10-28
Abstract: PURPOSE:To obtain highly reliable thermal cell in which the center of an igniter is struck with high reliability by simplifying the structure of an impact-type ignition device which is suitable for achieving complete sealing by suspending an impact core bar from the center of a beating part and making and beating part movable due to its flexibility. CONSTITUTION:A beating part 9 is formed by integrating an impact core bar 8 with a thin spring plate having plural concentric geooves 9a and 9b. When the core bar 8 is pushed by hand, the beating part 9 moves up and down. Next, the beating part 9 is set on an exterior lid 5 in such a manner as to close its hole, and the periphery of the beating part 9 is fixed to the exterior lid 5 by means of solder or silver solder 10. After that, an igniter 1 is set in an igniter holder 6 having a fire introduction hole 7 before an impact core holder 12 is placed on the holder 6, then the holder 6 and the exterior lid 5 are unified by welding. When impact force is applied to an ignition device (A) in the direction indicated by arrow (F), the core bar 8 is pushed before the beating part 9 moves down and vigorously strikes the igniter 1 which then produces flare. The thus produced flare is then introduced into the fire introduction hole 18 of the stacked body through the fire introduction hole 7 to cause the heating agent 14 of each layer to catch fire successively, thereby increasing the temperature of the entire fuel cell and melting the electrolyte layer.

Title: Flux cored wire for welding
Inventor: KASHIMURA TOSHISADA
IPC: B23K35/02
Filed: 1985-09-12
Abstract: PURPOSE:To improve the feedability and rectilinearity of a product as well as productivity by working a wire in such a manner that the elongation percentage epsilon on the outside surface in local bending attains a specific value. CONSTITUTION:A granular flux is packed in a metallic sheath. The elongation percentage epsilon on the outside surface in local bending expressed by the equation for such wire is so adjusted as to attain a 25-55% range. The feed resistance increases and the feedability is unstable in a curved feed system with the wire having <25% elongation percentage epsilon. In addition, rectilinearity is unstable as a result of stress relieving and disconnection in the process of production. On the other hand, the feed resistance increases with the wire having the elongation percentage epsilon exceeding 55%. The reduction of area necessary for drawing to the target sectional size as well as the size of the stock according to the decrease of the elongation arising from such drawing, the timing and condition for intermediate annealing and the grain size of the flux particles to be packed to the inside are adequately selected in order to attain the target elongation percentage epsilon. The feedability and rectilinearity of the product are thereby improved.
