Title: Camera
Inventor: FUJINO AKIHIKO
IPC: G03B7/16
Filed: 1988-05-17
Abstract: PURPOSE:To make a camera lightweight and compact without deteriorating operability by supplying power to a flash gun from the power source of a camera body and alternately switching a power supply state for charging the power source and a power supply state for control based on measuring of a timer. CONSTITUTION:A power supply means is designed which alternately switches the power supply state when a capacitor for accumulating flash energy for a flash gun removable from a camera body is charged from a power source 130 mounted to the camera body and the power supply state where a controller 200 for actuating devices is charged. To achieve the intention, the timer is provided, and moreover a switching means is provided which switches the power supply state for charging and that for control based on the measuring of the timer. Based on the recognition that the decreasing amount of a voltage outputting from the power source accompanied by charging the flash gun does not become great suddenly, switching said two states is controlled in turns of time. The camera can thereby be made lightweight and compact without deteriorating its operability.

Title: Thickness-sliding inflection crystal vibrator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/19
Filed: 1978-09-28
Abstract: PURPOSE:To improve frequency-temperature characteristics of a thickness-sliding inflection crystal vibrator by appropriately setting the side ratio of the vibrator. CONSTITUTION:Of a Y plate turned on the X axis by approximate 35 degrees, a crystal vibrator of (x0) in width, (y0) in thickness and (z0) in length is formed. At this time, setting its size with a ratio of width to thickness between 9.0 and 13.5 makes this vibrator cause not pure thickness-sliding vibration but thickness-sliding inflection vibration with combined inflection vibration, so that its frequency-temperature characteristics will be flat. Further, this vibrator is of the largest size in the Z'-axial direction and supporting it in the Z'-axial direction (z0 direction) makes it possible to reduce an energy loss at the support point. In this way, a miniature thickness-sliding inflection crystal vibrator with excellent frequency-temperature characteristics can be obtained by appropriately setting its side ratio.

Abstract: PURPOSE:To obtain a method for forming a colored image which is sharp and has excellent contrast by using a photosensitive material for diffusion transfer having the layer constitution consisting of a panchromatically dye-sensitized silver halide emulsion and back printing specification and using a silver complex diffusion transfer method, etching bleach method and coloring method. CONSTITUTION:The photosensitive material for diffusion transfer is exposed from the surface side having no silver halide emulsion layer and an image receiving material is superposed thereon. Both materials are passed through a processing soln. for diffusion transfer and are stripped; thereafter the direct positive type photosensitive material for diffusion transfer is used with the image receiving material on which the transferred image is formed as an original. Said photosensitive material is exposed from the surface having the silver halide emulsion layer and is superposed on the image receiving material, then both materials are passed through the processing soln. for diffusion transfer and are stripped. Then the two processes, i.e., the process consisting in processing the image receiving material on which the transferred image is formed with an etching bleach liquid to remove the silver image and the process consisting in using a dye liquid, dyeing the image with the dye and obtaining the dye image are executed. The silver halide emulsion which is panchromatically color- sensitized is used. The sharp color image having the excellent contrast is thus obtd.

IPC: F16K31/06
Filed: 1990-05-11
Abstract: PURPOSE: To reduce wear by absorbing load first by a valve head when an armature is drawn into a hole, and distributing to absorb final load by the valve head and a stopper acting between a stator and the armature. CONSTITUTION: A valve head 58 is radially overlapped on a flange 32 and formed in such wall thickness that the outer edge part of the valve head abuts the edge part of a flange 32 surrounding a hole 24 when a magnet coil 26 is excited and an armature 54 is drawn into the hole 24. When the armature 54 is drawn in, the valve head 58 first absorbs a part of load of the armature 54, and then a stopper 60 abuts a stator 34. Full load is not therefore absorbed only by the stopper 60 but absorbed first by the valve head 58 and then finally distributed and absorbed by the valve head 58 and the stopper 60. As a result, the operating state of a solenoid valve 10 becomes moderate, and the wear of the stopper 60 is reduced.

Filed: 1992-05-13
Abstract: PURPOSE:To obtain a steel plate for fuel tank of automobile high in corrosion resistance against the fuel and environment of salt damage and in mold workability by applying successively a tin layer, an electrotreated chromate film, an epoxy based coated film having a specific thickness. CONSTITUTION:The steel plate containing, by % by weight, <=0.002 C, 3-20 Cr, 0.005-0.10 acid soluble Al, if necessary, 0.03-0.05 one or more kind of Ti Nb, Zr, V in wt.% and balance Fe is coated with tin, is coated with the electrochromate film thereon and furthermore is coated with the epoxy coating film of 0.1-3mum. The steel plate containing >=3% Cr is excellent in corrosion resistance and in a tin plating steel plate, the steel is one-sidely corroded because the potential of tin is more positive than the potential of steel. When the content of Cr is above 20%, mold workability and weldability is deteriorated and the mechanical strength and corrosion resistance of the steel are lowered with increase in C content. When Al content is less than lower limit, the generation ratio of surface defect of the steel is high and when above upper limit, the soundness of plating is lost. When the thickness of the epoxy based coating film is less than the lower limit, tin is dissolved and when above upper limit, effect of preventing the elusion of tin is saturated.
