Title: Image forming device
Inventor: AKIYAMA SATORU
IPC: G03G15/04
Filed: 1989-09-08
Abstract: PURPOSE:To simplify a synchronizing mechanism by detecting that a recording medium passes through a prescribed position and transferring an image while synchronization is taken in a sub scanning direction. CONSTITUTION:When the recording medium P is fed to a transfer roller P by a paper feeding roller 2, a paper feeding sensor 5 detects that the paper P passes through the prescribed position. The synchronous signal generating means controls the driving of an optical unit as a latent image forming means in synchronization with a signal taking the timing of writing the image in the sub scanning direction onto a photosensitive body 6. The image is recorded on the prescribed position of the recording medium P being fed without being stopped. The sensor 5 is disposed in the upstream of a transfer position at a distance greater than that the leading edge of a latent image formed on the photosensitive body 6 moves from where it is developed to the transfer position where it is transferred onto the photosensitive body P. Thus, without the need for a complicated mechanism taking synchronization in the sub scanning direction, the recording medium can be synchronized in the sub scanning direction while it is being fed.

Filed: 1983-12-08
Abstract: PURPOSE:To obtain a high-sensitivity photosensitive material with few fogs by using an oxidizing agent for reducing or eliminating the function of a solvent for silver halide contg. sulfur to grow particles in promoting the growth of silver halide particles by using said solvent. CONSTITUTION:A solvent for silver halide contg. sulfur such as thiocyanate, organic thioether, a thionic compd., and a mercapto compd. is added when the particles of silver halide are formed or the particles are grown to promote the growth of the silver halide particles and to form the high-sensitivity particles. In this case, an oxidizing agent for reducing or eliminating the growth promoting function of said sulfur-contg. compd., for example, an oxidizing agent added with H2O2 such as H2O2, NaBO2.H2O2. 3H2O, and K2S2O3, or an oxidizing gas of organic peroxides are added at an optional needed time. However, an oxidizing agent which does not decompose gelatin and does not have a drastic sensitivity reducing function is preferably used. When an oxidizing agent is used in excess, a reducing agent such as sulfite is used at an opportune time to deactivate the oxidizing agent. The layer of the silver halide emulsion thus obtained is formed to obtain the high-sensitivity photosensitive material without any fogs.

Filed: 1988-09-19
Abstract: PURPOSE:To form a stopper during a wafer process by a method wherein a plurality of first protruding parts formed in a weight part and a plurality of second protruding parts formed in a support part are piled up via prescribed gaps in such a way that, for one part, the first protruding parts are situated at the upper part in a vertical direction and that, for the remaining part, the second protruding parts are situated at the upper part. CONSTITUTION:An Si support part 11, an Si weight part 12, an Si cantilever 13, first protruding parts 15 and second protruding parts 16 are formed during a wafer process. When an acceleration is applied to this sensor, the Si weight part 12 is displaced to an alpha1 direction or an alpha2 direction. When an excessive acceleration is applied, the first protruding parts hit the second protruding parts 16 if a displacement exceeds a prescribed value; thereby, the displacement is stopped. For example, when an ABC cross section is viewed, the first protruding parts 15 are stopped by the second protruding parts 16 for an excessive displacement in the alpha2 direction; when an AB'C' cross section is viewed, the first protruding parts 15 aye stopped also by the second protruding parts 16 for the excessive displacement in the alpha1 direction. Accordingly, even when the excessive acceleration is applied, it is possible to prevent the Si cantilever 13 from being damaged.
