Title: Image forming device
Inventor: SUGIURA MITSUSHI
IPC: B41J3/44
Filed: 1988-04-25
Abstract: PURPOSE:To prevent the occurrence of failures such as crinkled and jammed sheets by selectively loading an electrophotographic image producing unit and a printer unit of heat development type and adjusting the press-bond force of a fixing part when the printer unit is loaded. CONSTITUTION:A photosensitive body, an electrostatic charger, a developing device and a cleaner are united in the image producing unit 2, while a heat sensitive head, an ink ribbon roller, a take-up roll, etc., are united in the printer unit 22. When the unit 22 is loaded, a cam 53 on the side of the unit 22 pushes a pressure lever 51 to reduce pressure applied to an upper fixing frame 44 supported by a journal 43. Thus, the press-bond force between fixing rollers 41 and 42 is reduced enough to carry sheets, whereby failures such as their crinkles and jam can be prevented.

Title: Electrolytic capacitor
Inventor: AOSHIMA YOICHI
IPC: H01G9/035
Filed: 1987-04-27
Abstract: PURPOSE:To improve the life of an electrolytic capacitor at a high temperature, by adding monoethanolamine salt of polyoxyethylene lauryl phosphate or polyoxyethylene octyle phosphate to an electrolyte. CONSTITUTION:For an organic polar solvent such as ethylene glycol, 0.01-20 wt.% monoethanolamine salt of polyoxyethylene lauryl phosphate or polyoxyethylene octyle phosphate is added to a liquid in which carboxylic acid group or its salt is introduced as a solute. IN an electrolytic capacitor having these composition, no abnormalities appear even after 2000 hr. This shows a fact that monoethanolamine salt of polyoxyethylene lauryl phosphate shows an excellent protection against metallic corrosion.

Title: Figure separating circuit
Inventor: SHIYUDOU TOMOKI
IPC: G06V30/148
Filed: 1981-07-02
Abstract: PURPOSE:To separate figures and symbols in a specified dimension by setting a separation frame in which an apex obtained from status change between rasters of binary pattern obtained by horizontal scanning of a drawing is made to middle point of the upper side and expanding the frame to a reference value if required. CONSTITUTION:A drawing made to binary by horizontal scanning and presence of a signal is expressed by black and white (white is omitted in the figure) for each dot. The apex of the figure is determined from the change of status of existence of dots between rasters. For instance, in Figure A, there is no black dot in i-1th raster and black dots appear in i-th raster. Accordingly, it is judged that there is an apex of the figure in the raster (i), and an initial separation frame of width (DELTAw), height (DELTAh) (DELTAw=DELTAh=4 in the figure) is set making the middle point (c) are reference. There are two black dots on the left side, no dot on the lower side and one dot on the right side. As this is inseparable, it is expanded to left and right by w/2 and downward by h/2 to include in the frame. When the size exceeds the maximum size of the figure to be separated after repeating expansion, it is judged that the group of black dots on the apex is inseparable, and another apex is set.

IPC: G03G15/00
Filed: 1988-04-25
Abstract: PURPOSE:To obtain the device which provides high contrast and has the smaller dependency on environment and excellent durability by forming an image holding member of a conductive layer, diffusion reflecting layer and dielectric resin layer. CONSTITUTION:The image holding member of the display device for sticking fine magnetic powder which is conductive and is colored electrically to the image holding member is constituted of a conductive base 1, the diffusion reflecting layer 2 and the dielectric resin layer 3. The layer 2 is formed of fine reflective particles of org. resin powder or metal salt, etc., which are dispersed into a thermoplastic resin, etc. The layer 3 is formed of a thermoplastic resin or thermosetting resin. Thereby, the fine powder is removed by the microruggedness due to the fine reflective particles remaining on the surface of the layer 2 and the microgaps layer 3 generated in the inside. The degrade of the contrast at the time of repetitive use and the decrease of the electric resistance by the adsorption of moisture at the time of a high humidity are, therefore, prevented and the high contrast, environmental resistance and durability are improved.
