Title: Communication control system
Inventor: TATSUKE NOBORU
IPC: H04L29/08
Filed: 1990-08-23
Abstract: PURPOSE:To prevent the whole of a communication network from falling into the communication impossible state by suppressing an influence of trouble, by which a communication request signal is fixed to the active state, to a local range. CONSTITUTION:A selector 55 takes communication request signals SG, SH, and SO as the input and selects the communication request signal, which a selecting part 50 processes at present, in accordance with a signal (a) outputted from the selecting part 50 and outputs this selected signal to monitor parts 51 and 52. The monitor part 51 monitors whether the communication request signal applied from the selector 55 is made inactive within a first prescribed time t1 or not. The monitor part 52 monitors whether it is made inactive within a second prescribed time t2 for expiration of a timer 53 started by expiration of a timer 54 or not, and a monitor part 61 starts a liner 62 and monitors whether the communication request signal is made active within a third prescribed time t3 or not. Thus, an influence of trouble is suppressed to a local range to prevent the whole of the communication network from falling into the communication impossible state.

Abstract: PURPOSE: To prevent the surface of an electrifying member such as an electrifying roller from being mechanically damaged. CONSTITUTION: The electrifying roller 2 is rotated at a surface circumferential speed V0 by means of a photoreceptor 1 by utilizing frictional force at the time of contacting. Rotational force from a motor 30 is transmitted to a gear supporting shaft 34, a transmitting gear 33, a gear 32, an intermediate gear 31, and a roller driving gear 38 in the order through a driving force transmitting gear 36, a driving gear 35, and a one-way clutch 37 while it is decreased, so that the surface circumferential speed V in the case the roller 2 is away from the photoreceptor 1 is lower than the speed V0. Thus, heat generated in the case the roller 2 slides on a cleaning member is reduced, so that toner is prevented from adhering on the surface of the roller 2, and the surface of the roller 2 is prevented from being damaged.  A rotational force transmitting means can be constituted of a pulley and a belt.

Title: Fuel feed device for engine
Inventor: SHINDO TAKAO
IPC: F02M71/00
Filed: 1988-09-07
Abstract: PURPOSE:To prevent the increase of a fuel consumption amount by a method wherein a fuel injection valve is controlled by an electronic control system so that an amount by which a flow rate of fuel through a fuel port is short of a fuel demand amount of an engine is injected. CONSTITUTION:When an engine 6 starts running, a negative pressure is exerted on a fuel port 24 to suck out fuel in a constant fuel chamber 29 to an intake air line 4 to feed it to the engine 6. A difference between a fuel demand amount of the engine 6 and a flow rate of fuel sucked out through the fuel port 24, i.e. a deficiency, is injected through a fuel injection valve 8 controlled by an electronic control system. Thus, accurate control is demanded for opening and closing of the fuel control valve 8, and there is no need to set air-fuel mixture concentration to a value being high more than necessary only by fuel sucked out through the fuel port 24 during idling being low in fuel spraying ability, and an engine demand amount is met economically.

Title: Method for whitening titanium or titanium alloy
Inventor: SAKAMOTO NAOSHI
IPC: C23C8/10
Filed: 1989-08-31
Abstract: PURPOSE:To stably form a white film having a high strength and uniform color tone by forming a colored oxide film on the surface of a wire consisting of Ti or Ti alloy, then corroding the surface of the Ti metal surface under the film and further oxidizing the oxide film to an opaque white color and finally, impregnating a surface hardener into the white oxide film. CONSTITUTION:The wire of the shape memory alloy consisting of the Ti or Ni-Ti system is energized in an oxidative atmosphere and is heated to, for example, 300 to 500 deg.C to form the oxide film having the interference colors of gold   red purple   blue   golden, etc., on the surface by the film thickness thereof. The wire is then immersed into a liquid mixture composed of nitric acid, hydrofluoric acid and water to etch the underlying metal surface under the oxide film and to form fine ruggedness on the surface. The wire is in succession subjected to rinsing and drying and is again subjected to the electrooxidation until the oxide film shows the opaque white color. Finally, a transparent synthetic resin, such as 'Teflon(R)', epoxy or acryl system, is applied as a surface reinforcing material on the surface and is cured by baking, by which the film having the uniform white color tone is formed.
