Title: Ignition timing controller of internal combustion engine
Inventor: HIJIKATA JOJI
IPC: F02D21/08
Filed: 1993-09-13
Abstract: PURPOSE:To provide the ignition timing controller of an internal combustion engine capable of always getting the optimum ignition timing not only during a normal time, but also even during transfer from the outside of an exhaust reflux range to the inside of the exhaust reflux range, or vice versa. CONSTITUTION:A standard ignition timing thetaMAP is compared with a standard ignition timing thetaMAPT which is an ignition timing of the normal time with EGR (exhaust reflux) set ON (S64). The standard ignition timing thetaMAP is set to the standard ignition timing thetaMAPT of the normal time at the time of setting EGR ON, when the standard ignition timing thetaMAP becomes larger than the standard ignition timing thetaMAPT (thetaMAP>thetaMAPT) during the normal time with the EGR set ON (S65).

Title: Combustion flame detecting device for gaseous fuel
Inventor: ISHIDA TETSUYOSHI
IPC: G01N21/71
Filed: 1987-10-05
Abstract: PURPOSE:To accurately detect whether or not there is a flame from a combustion burner by providing the optical combustion flame detecting device with an optical filter which transmits only a specific light emission spectrum in front of a light emitting element. CONSTITUTION:The light emission spectrum from the flame 12 is guided to a light reception part 16 through optical fibers 14 and 15. The optical filter 25 which transmits only the light emission spectrum of high-temperature steam by receiving the light spectrum transmitted from the optical fiber 15 is provided in front of the light reception part 12. The spectrum passed through the optical fiber 25 is converted by the light reception part 16 into an electric signal when no frame is formed, thereby deciding whether or not there is a flame. Thus, the flame spectrum is detected in a specific wavelength range where the intensity is large to securely detect whether or not there is the flame.

IPC: G01F1/66
Filed: 1988-10-05
Abstract: PURPOSE:To eliminate the influence caused by a temperature variation by transmitting a tone burst-like signal, receiving it simultaneously by a pair of receivers placed in two directions of the direction running along a flow of a fluid and the direction going against said flow, and measuring a flow velocity of the fluid from a phase difference. CONSTITUTION:To a fluid which flows at a flow velocity Vx in the direction as indicated with an arrow, a tone burst-like ultrasonic signal is transmitted from a transmitter 2. Said signal is received simultaneously by a receiver 3 placed in the direction running along a flow of the fluid and a receiver 4 placed in the direction going against a flow of the fluid, and from a phase difference between the tone burst-like signals, a flow velocity of the fluid is measured. In such a way, the influence of a temperature exerted on a sound velocity can be negated, and also, the influence of an interference wave can be reduced.

Title: X-ray mask
Inventor: TANAKA RYOJI
IPC: G03F1/22
Filed: 1988-10-04
Abstract: PURPOSE:To execute a pre-alignment with high precision by a method wherein a reference plane positioned with respect to X-ray absorber patterns is provided, the reference plane comprises guide faces and the motion in the direction vertical to the surface of a mask is restrained by the guide faces. CONSTITUTION:X-ray absorber patterns 3 are formed on a mask substrate 1 and a holding substrate 5 bonded to a silicon frame 2 is formed. The substrate 5 is a reference plane, which is positioned accurately to the patterns 3 and has dovetail groove guide faces 4a and 4b. Here, as a pair of opposed edges of the substrate 5 are formed into the guide faces 4a and 4b, the motion in the direction vertical to the substrate 1 is restrained by the guide faces 4a and 4b. Thereby, in case a vacuum in a mask chuck is broken due to troubles, the fall of an X-ray mask is prevented. Moreover, as the X-ray mask can be positioned with the guide faces 4a and 4b as a reference at the time of installment of the mask, a pre-alignment can be executed with high precision.

Abstract: PROBLEM TO BE SOLVED: To obtain a protective film having good head-touching property and excellent reproducing characteristics by forming the protective film in such a manner that hardness in an upper layer film is lower than that in a middle and lower layer films. SOLUTION: This protective film has different hardness in the thickness direction in such a manner that hardness in the upper layer side is lower than hardness in the middle and lower layers.
