Title: Device for detecting failure of intake system of engine
Inventor: MIYAMA HIDEJI
IPC: F02D41/00
Filed: 1988-02-16
Abstract: PURPOSE:To prevent erroneous judgment at the time of starting engine by prohibiting judging output for a certain period after starting engine by a restricting means at the time of detecting the abnormality of an intake system based on a throttle opening, an engine speed, and an intake pipe inner pressure. CONSTITUTION:In an ECU 8, at the time of judging to be an idling operation, first, the opening of an ISC valve is calculated 80 from a water temperature, a throttle opening, and an engine speed. Also, based on the calculated value, the sectional area of the opening of the ISC valve is calculated 82 and the throttle opening is corrected from the calculated value and the throttle opening by a converting means 83, and the judging value PMF of an intake pipe inner pressure is calculated 84 from this throttle opening and the engine speed. This judging value PMF is compared 86 with a pressure sensor signal (intake pipe inner pressure) PM and, when PMF<PM, judgment is formed to be the failure of an intake system. In this case, if an engine starting time is judged by a starting time judging means 85, the output of an abnormality signal is prohibited by an abnormality judgment restricting means 87.

Title: Outboard motor
Inventor: SUMIKAWA YUKIO
IPC: F02B61/04
Filed: 1994-02-07
Abstract: PURPOSE:To surely cool an oil pan by a cooling water, and moreover to improve sound insulating ability with restraint put on the enlargement of exhaust noise. CONSTITUTION:An exhaust path is made to pierce an oil pan 21 and led below it, and the oil pan 21 and the exhaust path are covered by a common water jacket for cooling water. The inner space S of the oil pan 21 is also formed as a pa.rt of an exhaust expansion chamber. The oil pan 21 is immersed in the cooling water and effectively cooled. Since the cooling water in an outer space B serves as a practical sound insulating body to cover the exhaust path, low noise is produced. The exhaust expansion chamber is large in volume to further improve sound insulating ability.

Filed: 1978-03-22
Abstract: PURPOSE:To remove disturbance caused by noises by controlling a reference timing signal to a fixed phase, by generating a stop signal by receiving data and the reference timing signal by comparing the phase of a conversion signal with that of the reference timing by a phase comparator circuit. CONSTITUTION:By detecting the voltage change point of a receiving data signal, change point detection circuit 2 outputs a change point signal, and reference timing generating circuit 5 generates a reference timing signal under the control with the phase either advanced or delayed by a control signal for phase advancing, phase-delaying or stopping. For the purpose, phase comparator circuit 3 compares the phase of a conversion signal with that of the reference timing signal; and the reference timing generating circuit is supplied with a phase-advancing control signal when the conversion signal leads or a phase delaying control signal when lagging, so that stop signal generating circuit 4 will generate a stop signal controlled by the receiving data signal and reference timing signal. Consequently, the reference timing signal can be controlled to a fixed phase in order to remove disturbance caused by noises, etc.

Abstract: PURPOSE:To realize a semiconductor optical amplifying element having a high gain and high-gain satd light output. CONSTITUTION:An optical waveguide layer 11 consisting of a semiconductor for obtaining an optical gain and an optical waveguide layer 12 consisting of a semiconductor on the output side of this optical waveguide layer 11 are formed on a semiconductor substrate 1.

The width of the optical waveguide layer 12 is so set that the mode sectional area within the plane perpendicular to the propagation direction of the light propagating in the optical waveguide layer 12 decreases along the output side and that the ellipticity ratio (major axis/minor axis) of the mode section approaches 1. As a result, the gain satd. light output of the semiconductor optical amplifying element is increased and optical coupling loss is lessened in the case this light output is coupled to an optical system which is axisymmetrical, such as external single mode fiber.

Filed: 1984-02-23
Abstract: PURPOSE:To obtain a unified image pickup and display device by providing a light emission device to the image pickup part and utlilizing an optical system of the image pickup part. CONSTITUTION:Motion of photographing an object 1 is photographed by a light path in the direction of the arrow 13 and recorded in a recording circuit 6. Display is made by adding a recorded video signal to a CRT controlling circuit 10, performing CRT driving signal processing, adding to CRT11 and making the CRT11 emit light. An image displayed on the CRT11 is led to the direction shown by the arrow 11 through a half mirror 12 passing through an optical system 2. Accordingly, the image of the CRT can be displayed by providing a screen (not shown in the figure) in the direction shown by the arrow 14. A charge transferring section of an image pickup element is made to multi-layer structure, and a light emitting element 18 is provided and used as a display device. At this time, a charge transferring element 16 so far transferred received charge of a light receiving section. However, charge is applied to the light emitting element 18 at the time of display. Thus, by providing a light emitting element in a part of image pickup element, the half mirror 12 becomes unnecessary and the efficiency of light emission can be heightened.
