Title: Image formation device
Inventor: AKAO MICHITOSHI
IPC: G03G15/00
Filed: 1989-01-30
Abstract: PURPOSE:To constantly obtain good image for an image formation device provided with a supply means for supplying a paper sheet by performing a paper sheet carrying during inputting a power source and during restoration from a supply error. CONSTITUTION:In inputting a power source and in the generation of a supply error, a development paper 16 is separated from a sucker, which is then moved upward, and is withdrawn from a paper sheet carrier passage. In case a paper sheet is left behind in a carrier route, after a pinch roller 19b is pressed to a roller 19a by a step motor 73, rollers 19a, 19b are rotated to carry the predetermined development paper 16. At the time, a signal from a supply sensor 74 is checked. If the presence of a paper is detected by the supply sensor 74, paper sheet carrying is stopped, and the rollers 19a, 19b are released so as to display paper jamming on a display 75. When the development paper 16 is not detected by the sensor 74 during the carrying a predetermined amount, the development paper 16 is judged not to be left on the carrier route, and the next process is carried out.

IPC: F01N3/02
Filed: 1990-02-01
Abstract: PURPOSE: To further accelerator the evaporation of supplied fuel by constituting a protective sleeve of a glow plug by a fine wire fabric or a wire assembled material. CONSTITUTION: A scope of a glow wire 25 of a glow plug 22 is coaxially surrounded by a protective sleeve 26 of a thin wall across a distance in the radial direction. Moreover, a conduit connection part 27 of a fuel supply conduit 28 enters a glow plug receive chamber 11 in the radial direction and an opening 29 reaches just ahead of an external wall of the protective sleeve 26. Here, since the protective sleeve 26 is made of a fine wire fabric or a wire assembled material, a surface area of the protective sleeve 26 is markedly large. Consequently, the wire fabric or wire assembled material of the protective sleeve 26 is rapidly heated, very uniform evaporation of fuel colliding therewith is promoted, and a burning body in an air-fuel adjusting chamber 10 becomes unnecessary.

Title: Optical time-division multiplexed modem circuit
Inventor: TAKEMOTO KENJI
IPC: G02F3/02
Filed: 1988-01-29
Abstract: PURPOSE:To cope with a high-speed signal with the title circuit by using optical nonlinear elements and star couplers and performing time-division multiplexed MODEM signal processing in an optical stage. CONSTITUTION:An optical nonlinear element 17-1 outputs a high-level output only when the input #1 is '1' at the phase of optical clock pulses and, similarly, optical nonlinear elements 17-2-17-4 output high-level outputs only when the inputs are '1' at phases shifted from the phase of the optical clock pulses. When the elements 17-1-17-4 output high-level outputs, the optical signal output SO of an optical star coupler 19 becomes time-division multiplexed modulation signals. Moreover, an optical nonlinear element 37-1 output a high-level output only when the input #1 is '1' at the phase of the optical clock pulses, and similarly, optical nonlinear elements 37-1-37-4 output high-level outputs only when the inputs are '1' at phases shifted from the phase of the optical clock pulses. The outputs are held during the period T. Thus time-division multiplexed demodulation signals are respectively outputted as optical signals to the optical signal output R# of output ports. Therefore, a super-high speed time-division multiplexed MODEM system of 10GHz can be realized.
