Title: Controller for engine with supercharger
Inventor: YOSHIOKA MAMORU
IPC: F02B37/18
Filed: 1991-04-10
Abstract: PURPOSE:To reduce a torque shock caused when the operation of only a main supercharger (single supercharging stage) is changed over to the operations of both main and sub-supercharger (double supercharging stage). CONSTITUTION:An exhaust bypass valve 32 and waste gate valve(WGV) 42 are provided for equalinzing the supercharging pressure of both supercharging stages to each other. A CPU controls the WGV 42 when an exhaust change-over valve 23 is opened to change over 'single' 'double' so that the supercharging pressure is reduced a fixed amount lower than intake pipe pressure PMBO right before the opening of the exhaust change-over valve 23 and gradually reqained. That is, while the CPU stores the intake pipe pressure PMBO right before the change-over of stage by an intake pressure sensor 62, the CPU obtains a drop rate B of supercharging pressure on the basis of a map specifying the drop rate B of the supercharging pressure for a passage time after the change-over of stage. Desired supercharging pressure PMW is figured out by multplaying the intake pipe pressure PMBO by drop rate B of supercharging pressure to adjust the opening of the WGV 42 so that then intake pipe pressure PM is PMW.

Title: Surface acoustic wave converter
Inventor: TAKAHASHI SEIICHIRO
IPC: H03H9/145
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To efficiently and stably excite surface acoustic wave without any notch in the frequency characteristic in a using band by specifying the length of crossing part of positive and negative electrodes, the length of their noncrossing part and the width of bus bars, which are respectively parts of interdigital electrodes, at a prescribed ratio. SOLUTION: When the length of crossing part of electrodes 1, 2 of an interdigital electrodes is set a1, the length of noncrossing part is set a2 and the widths of the bus bars 3 and 4 to be a3, the values of a1 to a3 are respectively varied to satisfy a prescribed relation to prevent the generation of a notch frequency. A notch exists not only in a specific frequency but exists with specific distribution by setting a specific frequency to be a peak. Then, the existence of the notch with respect to frequency characteristic causes the increase of an insertion loss not only in a specific frequency but extending the whole using band. Namely, the insertion loss can be reduced by preventing the notch.

Abstract: PURPOSE:To discriminate a target object and its background even in case a luminance difference of both of them is not sufficient, and to recognize exactly the object by providing a color extracting device, a picture emphasizing device and a color information setting device. CONSTITUTION:Picture data of each separate color inputted to memories 7, 8 and 9 through a color signal separator 2, etc. from a color TV camera 1 are outputted to a color extracting device 10. The device 10 converts an input picture data so that it becomes color information which is not generated by the brightness, and outputs it to a picture emphasizing device 11. The device 11 forms a picture data related to whether both color information is similar or not from the color information inputted from the device 10 and the color information inputted from a color information setting device 12. This picture data becomes a larger value by the extent that the input picture is different from a color of a pattern picture set in advance to the setting device 12, and becomes smaller value as it becomes approximate. In this way, a difference of the pattern picture and its background is emphasized, and even in case when a luminance difference of a target object and its background is not sufficient, both of them can be discriminated, and the object can be recognized exactly.
