Title: Atmospheric pressure correction device of internal combustion engine
Inventor: ISHIHARA SHINYA
IPC: F02M23/04
Filed: 1978-08-04
Abstract: PURPOSE: To properly correct air fuel ratio continually, by mounting a by-path that a flow-rate control valve, which calculates the quantity of air corrected in response to the change of atmospheric pressure and is driven by the signals, is installed between an upper stream portion of a Venturi and a lower stream of a throttle valve.  
     CONSTITUTION: Air filtered by means of an air cleaner 1 passed through an intake system 2 and a by-path 4 and is supplied to an engine E. A pressure sensor 13 detects the pressure of an upper stream of a Venturi portion 2a, a pressure sensor 10 the negative pressure of the Venturi, a pressure sensor 12 the thrust of intake and a pressure sensor 11 atmospheric pressure. When atmospheric pressure changes, the optimum quantity of air corrected at that time is counted by means of a computing circuit 14 on the basis of pressure signals detected by means of each pressure sensor 10, 11, 12, 13, and an opening of a flow-rate control valve 9 is controlled by the output, thus appropriately correcting air fuel ratio all the time.

Title: Electrolytic capacitor
Inventor: IKEDA YOSHISHIGE
IPC: H01G9/08
Filed: 1990-04-11
Abstract: PURPOSE:To realize a power rectifying circuit for audio abundant in musicality by forming the bottom of a case into curved face, in the electrolytic capacitor stored and sealed in a case provided with a bottom. CONSTITUTION:A rolled capacitor element 6 is stored in a case 7 provided with a bottom and a sealing plate 8 is fitted in the opening of the case 7, and is tightened by a screw, whereby the case is sealed. The bottom 7a of the case 7 provided with a bottom is formed into a curved face, and the outer block 7b at the bottom of the case is formed in elliptic shape. And the peripheral length of the outer block 7c of the case opening sealing part is made longer than the peripheral length of the outer block 7b at the bottom of the case, so it is trapezoidal in one direction. That is, since the bottom of the case 7 provided with a bottom used for an electrolytic capacitor is made in curved face, resonance phenomenon does not occur, and it does not produce the mode which reflects and resonates to specific frequency. Hereby, very fresh sound quality, wherein the regenerated sound in the audible frequency band ranging from low sound to high sound is flat, can be obtained when it is used for the power rectifying circuit of audio equipment.

Filed: 1989-04-17
Abstract: PURPOSE:To enable reproduction in a forward direction also in a backward direction by encoding an image other than a frame setting the decoded image of the image existing nearest to the image in the images encoded in the frame as a reference image. CONSTITUTION:For example, when a moving image is accumulated in an accumulation medium, a targeted image is encoded to the moving image in the frame with an appropriate frame interval, and the image other than that is encoded between the frames by an in-frame encoder 18 setting the decoded image of the image encoded in the frame as the reference image. In reproduction, the image encoded in the frame is decoded and displayed, and simultaneously, it is accumulated in a frame buffer 20, and the image encoded between the frames is encoded and displayed by using the reference image accumulated in the frame buffer 20 by a decoder 19. Thereby, the reproduction can be performed by using encoded data commonly in the forward and backward directions, and encoding can be performed with high efficiency.
