Title: Accidental fire detecting method by crank shaft rotational fluctuation
Inventor: MATSUMOTO TAKUYA
IPC: F02P17/12
Filed: 1993-02-05
Abstract: PURPOSE:To accurately detect the presence or absence of occurrence of an accidental fire in respective cylinders of an engine without requiring any special hardware. CONSTITUTION:Angular accelerations Domegan-2, Domegan-1, Domegan and Domegan+1 in a crank angle range corresponding to a preceding cylinder, two cylinders subjected to the detection of an accidental fire and a succeeding cylinder are subsequently calculated. When the values Domegan-1, Domegan are considerably decreased in comparison with the values Domegan-2, Domegan-1, it is suppositively judged that an accidental fire occurs in both cylinders subjected to the detection of an accidental fire, next, when the value Domegan+1 is considerably increased in comparison with the value Domegawn, the returning to the normal burning state is ascertained, and then the occurrence of an accidental fire in two cylinders subjected to the detection is definitely judged.

Title: Solenoid valve for fluid control
Inventor: HIRAMATSU RYOHEI
IPC: F16K31/06
Filed: 1988-01-30
Abstract: PURPOSE:To suppress the cost and enhance the sealing performance by forming a ring groove at the end face of a valve element to make contact with the valve seat, and fitting a ring-shaped resilient packing in this groove. CONSTITUTION:A ring groove 8 with approx. triangular profile is formed at the top surface of a valve element 7, which seats itself and moves apart from a valve seat 5 formed at a housing 1 to block or open a communication hole 4.

Abstract: PURPOSE:To make it possible to form a developer coating on a developer supporting means to an invariably uniform layer thickness, by arranging a developer-layer restricting means for the developer supporting means in the area at the side of the rotating and ascending surface of the supporting means. CONSTITUTION:Rotary sleeve 2 as a developer supporting means is provided with blade 4 as a developer-layer restricting means in the rotating and ascending surface side area of sleeve 2 and at the ascending and rotating angle position of about 90 deg. to the lowermost surface position of sleeve 2.

Filed: 1984-02-06
Abstract: PURPOSE:To improve the strength of a diffraction grating pattern consisting of photoresist and to prevent effectively cracking of the diffraction grating pattern under environmental conditions by coating a silane coupling agent as a precoating layer. CONSTITUTION:A silane coupling agent has a group bondable with an org. resin and a group bondable with an inorg. group and is gamma-glycydoxypropyl trimethoxysilane, etc. The treatment is executed by dissolving said agent in a solvent and coating and drying the soln. Photoresist is then coated thereon and is subjected to holorgram recording. For example, a diffraction grating 35 is formed via silane coupling agent coating layer 33 on a glass substrate 31. An inter-grating spacing D can be controlled by the angle between the two luminous fluxes interfered on the photoresist and the wavelengths of the luminous fluxes. A grating depth (h) can be controlled by controlling prebaking conditions, exposing time, developing time and concn. of a developing soln. The grating is then subjected to necessary post treatments such as rinsing, drying and post baking.
