Title: Preparation of ultrafine electrically conductive fiber
Inventor: OKAMOTO KAZUYOSHI
IPC: D01F8/04
Filed: 1981-02-26
Abstract: PURPOSE: To obtain the titled fibers useful as a suede artificial leather, etc. without broken fibers and dripping, by extruding a core component containing electrically conductive carbon into an island component, enclosing the island component in the sea component, processing the fibers into a fabric, and separating the sea component.  
     CONSTITUTION: A sea component (C), e.g. 2-ethylhexyl acrylatestyrene copolymer, is extruded in a stable extruding state, and a sheath component (A), e.g. nylon 6, is extruded to be present in the sea component (C) in the form of islands. A core component (B), e.g. nylon containing carbon, containing electrically conductive carbon is then extruded into the sheath component (A) and spun to give island-in-sea fibers, which are then processed into fibers, fabrics or sheets. The sea component or the interposing component (C) is then separated to give the aimed fibers having the island component ≤0.8 denier in which plural island components are enclosed by the sea component or plural sheath-core fibers ≤0.8 denier are linked with the interposing component (C).

Inventor: MITSUYAMA EIHACHI
IPC: B41F17/10
Filed: 1986-02-07
Abstract: PURPOSE:To make the cutting and selling of a required length possible without using any measuring instrument, by a method wherein the back of a cloth 2 is exactly printed by an effective winding (m) by rotation of an annular belt at the same speed as the winding speed of the winding cloth. CONSTITUTION:The seals 3, 3', 3'', 3'''... continuously indicating the number in (m) on the one surface of the annular belt 2 of a narrow width strip state made to be of the same length as that of a winding cloth 1 and the projected seals 4, 4'... are arranged over its total length and at the same time, stretched across without loosening. An ink roller 19 is touched to the seal of the annular belt 2 via a lower roller 13, besides the annular belt 2 touches the winding cloth 1 on the cloth feed roller 25 at the front end of the working machine 24 working the winding cloth 1 and the seals of the annular belt 2 print the back of the winding cloth 1. The titled instrument is composed of such an arrangement. Because the winding cloth 1 and the annular belt 2 are always made to have the same rotation speed, the seals arranged on the belt 2 never make the slippage of printing on the back of the winding cloth 1 and the accurate printing is carried out.

Filed: 1990-02-06
Abstract: PURPOSE:To prevent generation of damage due to heat to a heating body and a film by providing a means to separate a pressurizing member from the heating body and inhibiting separation of the pressurizing member during image formation. CONSTITUTION:The pressurizing roll 5 is brought into a pressurized contact with the heating body 1 by the energization of a coil spring 7 through a pressurizing lever 6.

Title: Logic circuit simulator
Inventor: UEDA TOSHIHIRO
IPC: G06F11/25
Filed: 1990-02-06
Abstract: PURPOSE:To eliminate a transient signal variation by constituting the logic circuit simulator so that a delay element for adjusting the timing of all input signal variations of each element for constituting a logic circuit can be inserted virtually. CONSTITUTION:Based on a connecting description inputted by a connecting description input module 5, the number of stages of an element for passing through by back-tracing a path for reaching an external terminal from one input terminal of one element is counted. Subsequently, this count is executed with regard to all input terminals of the above element. Next, the maximum value of the number of stages of the above element is derived, and a difference to the number of stages of the above element of each input terminal is calculated. In the case of a unit delay logical simulation, a value of the number of stages of the element becomes a value of a delay. Accordingly, by inserting a delay element having a value of a delay corresponding to the number of stages of the above element into each input terminal, the timing of a variation of all input signals is adjusted. This processing is executed with regard to all the elements for constituting the logic circuit.

Title: Automatic rewinding camera
Inventor: AKIYAMA KAZUHIRO
IPC: G03B17/42
Filed: 1981-02-27
Abstract: PURPOSE:To rewind a photographic film even if it is torn at some perforation by generating a film running signal synchronously with a body of revolution rotated as the photographic film is run and by resetting a timer circuit, which has shorter delay time than one frame for starting the reversing of a motor, by said generated signal. CONSTITUTION:A driven sprocket 62 rotated in engagement with the running of a photographic film 4 is provided to generate a film running signal, by which a timer circuit having shorter delay time than one frame is reset. Therefore, the film running signal is not generated synchronously with a driving sprocket 30 which advances the photographic film 4 by a motor 1. Consequently, even if the film is torn at its perforation 4a by the driving sprocket 30 to operate a frame advancing mechanism which controls a one-frame advance by the motor, the timer circuit operates to form a reversing circuit for the motor 1 before the frame advancing switch S3 of the mechanism turns off, thereby rewinding the photographic film 4 automatically.
