Title: Fuel injection device for gasoline engine
Inventor: SHIRASAWA KAZUJI
IPC: F02D45/00
Filed: 1990-06-15
Abstract: PURPOSE:To exactly detect failures by comparing measured, respective time intervals between the times when air-fuel ratio feedback corrections are performed, and identifying abnormalities of specified air-fuel ratio measuring means when the ratio of the time intervals becomes above a constant value. CONSTITUTION:A control device 13 has an air-fuel ratio feedback correcting means for correcting the fuel quantity in an intake system based on information from air-fuel ratio measuring means 7, 8 so that an intake mixture reaches a theorefical air-fuel ratio. The time intervals between the times when air-fuel ratio feedback corrections are performed, are respectively measured, and the respective time intervals are compared to each other. When the ratio of the respective time intervals reaches above a constant value, abnormalities of the specified air-fuel ratio measuring means 7, 8 are identified. Thus, even when the air-fuel ratio measuring means 7, 8 are inperfectly broken, or they are deteriorated to make responded output worse, etc., exact failure detection can be performed.

Filed: 1992-06-17
Abstract: PURPOSE:To compensate the branch loss and excess loss of the coupler and to equally distribute a light signal of the output larger than an input light signal to an output side by using the light power amplification type optical fiber having plural cores within one clad. CONSTITUTION:Two multicore fibers 61 and 62 added with rare earth elements having nearly equal structure parameters are bundled and while these fibers are heated, the fibers are fused and stretched to form a fused and stretched part 7 which is thinned in the central part. Light coupling and distributing effects are executed in this fused and stretched part 7. The multicore fibers 61 and 62 added with the rare earth elements are constructed by embedding plural pieces of cores 8 which are added with Er and have a refractive index nw (nw>nc) into clads 9 which have a refractive index nc. The quantity of the Er to be added into the respective cores 8 can be reduced as the number of the cores 8 is larger. The degradation in the amplification efficiency by the extinction of concn. is suppressed.

IPC: G03G15/36
Filed: 1988-06-29
Abstract: PURPOSE:To uniformly electrify a photosensitive body and to make uniform the quality of a copy by operating an electrifier and an erase device before an image forming stage starts, and entering the image forming stage after rotating a photosensitive drum at least once or over. CONSTITUTION:The erase device 3 is a light source for achieving image shift (for instance, the function of forming a space for filing) and image composition (the function of forming images of two originals on a single copy). It is used for erasing a charge of the photosensitive body independent of image exposure by an image exposing device 4 after the electrifying stage. Before image forming stage of the copying device starts, the electrifier 2 and the erase device 3 are made operable, and operation enters the image forming stage after rotating the photosensitive drum 1 once or more. The photosensitive drum 1 is uniformly fatigued in terms of electrification and photoelectricity, whereby a uniform copy can be stably obtained.

Title: Semiconductor memory
Inventor: TAGUCHI MASAO
IPC: G11C11/407
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To speed up the access by strongly driving a data device by operating a sense amplifier with a voltage equal to or higher than the voltage to be applied to memory cells and operating cells with an optimal voltage independently of the sense amplifier. SOLUTION: A data bus DB is connected to a sense amplifier by turning transistors Q35 and Q36 on by outputting a column selecting signal CL1 when voltages of the output terminal of the sense amplifier become larger to some extent. Next, the potential of the H level side of the sense amplifier rises to a potential near a Vcc while driving also the data bus. The BL1a on the H level side of bit lines does not rise to 1.6 volt or higher since a transistor Q1a starts being turned off in the vicinity of 1.6 V. Thus, the power consumption of an array can be reduced while attaining the high speed access by stipulating the restore voltage of the bit lines by restricting voltages at gates of transistors connecting the bit lines and the sense amplifier in this manner and by driving the sense amplifier with voltage equal to or higher than this voltage.
