Title: Optical cable
Inventor: KITAYAMA YOSHINOBU
IPC: G02B6/44
Filed: 1992-12-01
Abstract: PURPOSE:To suppress the receipt of a side pressure from side walls and to provide the optical cable of low transmission loss by adopting the structure that the optical fibers at both ends of laminated fiber ribbons hardly come into contact with the inside walls of coated fiber grooves. CONSTITUTION:The fiber ribbons 3 are housed into the fiber grooves 2 of spacers 1 with spiral grooves, by which optical fiber units 4 are constituted. These optical units are doubled and twisted around a tension member 5 and are applied with a sheath 7, by which the optical cable is constituted. Tape members 7 broader than these fiber ribbons 3 are laminated above and below the fiber ribbons. The contact of the ends of the fiber ribbons 3 with the inside walls of the fiber grooves and the receipt of the side pressure are prevented by the presence of the tape members even if the fiber ribbons are inclined within the grooves by application of external force, such as bending, on the optical cable. The degradation in transmission characteristic by microbend loss is thus prevented.

Title: Control device for variable valve system type internal combustion engine
Inventor: FUJIWARA KEISUKE
IPC: F02D13/02
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To improve uncomfortable behavior at the time of stopping an engine and to improve the startability of an engine. SOLUTION: When engine speed Ne is the specified value N1 or lower (S1), the engine speed Ne is controlled by the increase/decrease of cylinder internal pressure by bringing the closing timing of an intake valve close to the top dead center or bottom dead center so that the engine speed Ne is the target engine speed N (S2-S6). The engine speed Ne at the time of stopping the engine can thereby be damped with an ideal characteristic to improve uncomfortable behavior. To improve the startability of the engine, the intake valves of a pair of cylinders at the same crank angle are closed near the top dead center immediately before the stop of the engine. The internal pressure of the cylinder is thereby boosted to stop a piston near the top dead center.  Consequently, if an intake stroke is started from this cylinder, cylinder discrimination, fuel injection and air intake are rapidly carried out to shorten time required for the start of the engine.
