Title: Controller of engine
Inventor: SHIMIZU MAKOTO
IPC: F02D41/02
Filed: 1988-01-29
Abstract: PURPOSE:To effectively restrain the reduction in fuel consumption in the transient time when a school control valve is changed over to be opened or closed by providing a change-over timing setting means which sets the fuel supply timing changed over by a fuel supply timing changing means, during the period when the control valve is being closed. CONSTITUTION:With a school control valve 15 closed, intake air is supplied from a small-diameter intake port 5a only to generate school of mixture and with the school control valve 15 open, intake is supplied from both intake ports 5a and 5b to generate no school of mixture. At this time, a fuel supply timing change-over means 35 changes the timing at which fuel is injected from a fuel supply means 21, to that within an intake stroke when the position of the valve 15 is within the closed range, and to that out of the intake stroke when that position is within the opening range, whereby providing satisfactory mixture state of fuel. Since a change-over timing setting means 36 sets the change-over timing to select the area within the intake stroke or out of it when the valve 15 is in the closing position only, the reduction in fuel consumption in connection to the opening and closing action of the valve 15 and the change-over of fuel injection timing may be restrained effectively.

Title: Radio wave absorbent prepreg
Inventor: SO SATORU
IPC: H05K9/00
Filed: 1991-02-13
Abstract: PURPOSE:To enable a radio wave absorbent to be prevented from deteriorating in mechanical strength and easily controlled in a narrow range of width by a method wherein carbon fiber or silicon carbide fiber is impregnated with thermosetting resin. CONSTITUTION:Prepreg 1 is formed into a sheet, and fiber base material 2 is impregnated with thermosetting resin 3. The prepreg 1 can be obtained by impregnating the fiber base material 2 with thermosetting resin 3 through a conventional method. The fiber base material 2 is formed of carbon fiber or silicon carbide fiber which can be optionally changed in resistance. For instance, conventional fiber such as nykalon fiber or chilano fiber can be used as silicon carbide fiber. The thermosetting resin 3 is, for instance, epoxy resin, BMI resin, or polyimide resin. Moreover, the thermosetting resin 3 can be compounded with hardening agent, if necessary. By this setup, a radio wave absorbent of this design is hardly lessened in mechanical strength as compared with a case where magnetic substance powder such as ferrite powder is mixed.

Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To surely and accurately realize the tape cassette insertion detecting operation and to expand operation life of each component by always assuring smooth sliding of a slide lever for the stage.

IPC: G01M11/00
Filed: 1991-01-21
Abstract: PURPOSE: To clarify the property of an optical fiber and effectively design a receiver for an optical communication system by using the free-space wavelength of a light carrier wave, the length of a single-mode optical fiber and modulation frequency to find a color dispersion coefficient. CONSTITUTION: The free-space wavelength of a known or measured carrier wave signal and the length of an optical fiber in a single mode or a proceeding time for an optical signal are input to a light wave component analyzer to perform calibration and measurement with a short optical fiber. Then, the minimum value (the smallest point) in a graphic display or modulation frequency at a zero point is measured by using light frequency regarding the AM frequency response property of the optical fiber in a single mode. At this time, bias at a right angle to a positive/negative gradient is applied to an optical modulator for the light carrier wave signal to measure the frequency at a zero point twice so that the measurement values can be averaged to improve the accuracy of measurement.  A marker is aligned to the first zero point and the free-space wavelength, the length of the optical fiber and the modulation frequency at a zero point are used to calculate a color dispersion coefficient in ps/nm/km display.

When it is coded data, it is synchronism- converted so that it is synchronized with frame synchronism of a video signal by a frame memory 11. When coded data is connected to LPCM and recorded in an audio signal recording region on a magnetic tape, a changeover switch 17 is controlled, and dummy data is recorded in the prescribed period after LPCM. Further, when reproduced audio information is coded data, an output processing circuit 61 is bypassed.

Abstract: PURPOSE:To enhance cleanability of an image bearing body with a simple and small-sized structure by installing the feeder of a cleaning agent between a de- veloping zone and a regulating member, and using a magnetic member for at least one part of said feeder. CONSTITUTION:Dense magnetic force lines are generated between a magnet roll 9 in a sleeve 10 and the magnetic member 14 of a cleaning agent support member 13. A conveyed developer T is allowed to form a brush. Since the magnetic force lines are fluctuated in the direction and strength by the rotation of the roll 9, this brush is vibrated and stirred, and the flow of the conveyed developer is made uniform. The cleaning agent layer C held with the support member 13 is scraped by this vibration and stirring action, and at the same time, it is uniformly distributed on the surface of each developer particle. Besides, since the scraped agent is spread on an image bearing body 1 in a developing zone 17 in an early stage, deterioration due to the agent can be prevented and cleanability can be enhanced.
