Title: Fuel pressure control device for engine
Inventor: NAKAMURA YOSHITATSU
IPC: F02D41/30
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To improve hot restarting performance of an engine. SOLUTION: In a non-return fuel pressure control system, the fuel pressure is feedback-controlled to a value suitable for a fuel supply amount. In such a system, fuel vapor generation is suppressed by heightening a target fuel pressure and increasing the actual fuel pressure, when water temperature at the time of stopping an engine exceeds a heat resistance determination value. Under the normal condition where the water temperature is the heat resistance determination value or lower, fuel leakage from a fuel injection valve is suppressed by setting the target fuel pressure to be a target fuel pressure during idling. It is therefore possible to respectively prevent overlean and overrich phenomena of an air-fuel ratio, and improve restartability of the engine.

Title: Roller breakage detecting device for roller hearth kiln
Inventor: YAMAGUCHI MINORU
IPC: G01V8/20
Filed: 1991-12-24
Abstract: PURPOSE:To provide a roller breakage detecting device for a roller hearth kiln which enables reliable detection of breakage of a roller by a simple equipment. CONSTITUTION:A projector 8 arranged to the outside of a furnace inlet 2 of a furnace body 1 and in a position below the axis of a roller generates a photo signal in the direction of the length of a furnace. A light receiver 10 arranged to the outside of a furnace outlet 3 of the furnace body 1 and in a position below the axis of the roller is provided in a manner to independently receives photo signals generated from each projector 8. During normal rotation of the roller, beams emitted from the projector 8 are inputted to the light receiver 10 without being shut out. When breakage occurs to a roller 5, the roller 5 is dropped and inclined under gravity. In which case, a part of beams emitted from the projector 8 are shut out by means of a roller breakage piece. Thus, since beams to the light receiver 10, corresponding to the shut out beams, are shut out, breakage of the roller is reliably detected.

Title: Pressure sensor
Inventor: MATSUMURA TAKASHI
IPC: G01L9/00
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To reduce the temperature difference between a pressure detecting element and a signal processing element so as to improve the output of a pressure sensor by a method wherein the pressure detecting element is connected to a thermally good thermal conductor and the good thermal conductor is extended to a chamber for the signal processing element. SOLUTION: A pressure detecting element 21 is connected thermally to a lead frame 42 as at least one good thermal conductor, and the good thermal conductor is extended to a chamber 13 for a signal processing element. A gas which is introduced from a pressure source into a chamber 12 in which the pressure detecting element 21 is installed follows the temperature of the pressure source so as to be set to an unstable state. On the other hand, since the chamber 13 in which a signal processing element 22 is installed is a comparatively closed space, it is in a state which is stable in terms of temperature. In addition, due to the heat capacity of the chamber 13 as a whole, the temperature of the signal processing element 22 is nearly equal to the temperature of the chamber 13 so as to be stable.  In addition, since the pressure detecting element 21 and the thermally connected good thermal conductor are covered with a protective gel 71 whose heat insulating effect is large, the heat energy of the gas which is introduced into the chamber 12 for the pressure detecting element and that of the pressure detecting element 21 are hard to move.
