Abstract: PROBLEM TO BE SOLVED: To permit the measurement of the transfer function of a system to be controlled with sufficient accuracy in multiple-degree-of-freedom vibration control, by randomly changing the phases of sinusoidal-wave signals for driving shakers. SOLUTION: At the time of creating sinusoidal-wave signals for driving a plurality of shakers, a sinusoidal-wave signal creating part 11 randomly changes the phases between the sinusoidal-wave signals and simultaneously shakes the shakers by the created signals. A spectrum computing part 12 converts the shake signals and response signals sampled at the time of the shaking into the data of a frequency axis by Fourier integral, etc., and computes a one-time self spectrum and mutual spectrum. This process is repeated a plurality of times to compute self spectrums and mutual spectrums, they are stored in a spectrum storage part 13, and their mean value is obtained at an arithmetic mean processing part 14.  Then a transfer function computing part 15 computes a transfer function at a specific frequency (the frequency of the sinusoidal- wave signal at the time of shaking each shaker) from the mean value, and it is sequentially accumulated in a transfer function storage part 16 to compute the transfer function of all frequency components.

Title: Fuel injection system
Inventor: HONDA YOKO
IPC: F02M41/14
Filed: 1986-06-05
Abstract: PURPOSE:To make it possible to independently control the feed rate of oil, by opening and closing a relief passage for a pump chamber with the use of a solenoid valve to control the timing of fuel injection, and by adjusting the rotation of a cam ring to control the feed rate of oil during initiation of pressure feed. CONSTITUTION:Plungers 20,... are reciprocated under action of a cam ring 23 when a rotor 2 is rotated in association with the rotation of an engine so that a plunger chamber 19 and a pump chamber 3 fall in pressurized and vacuum conditions so that fuel is sucked up from a fuel tank into a sucking passage 6 through a check valve in the vacuum condition while a relief passage 8 is closed to initiate fuel injection when a solenoid valve 9 is turned in the pressurizing condition. Further, when the solenoid valve 9 is turned off after a predetermined amount of fuel injected, the relief passage 8 is opened to complete the fuel injection. In this arrangement, if it is desired to delay the timing of fuel injection, when a cam ring 23 is rotated by means of a rotary lever 25, the plungers 20 may pushed by even a low cam rise section during initiation of pressure feed, and therefore, the feed rate of oil may be lowered. Thus, it is possible to obtain a fuel injection characteristic in accordance with the operating condition of the engine.

Title: Multilayered recording medium and information reproducing device for the medium
Inventor: OZAWA KANEFUMI
IPC: G11B7/24035
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To simultaneously reproduce plural recording layers of the multilayered recording medium, in which information is recorded in plural recording layers by the bits that reflect or pass each different frequency component, by irradiating the radio waves that include plural frequency components assigned to plural recording layers and distributing the radio waves reflected from the multilayered recording medium for every frequency component. SOLUTION: A multilayred disk 4 is provided with n reflection film layers in which information is recorded. Each layer has a characteristic to reflect or pass different frequency components λ1 to λn. A radio wave radiator 1 radiates radio waves 8 having the components λ1 to λn against the disk 4. A radio wave receiving section 5 divides reflected radio waves 9 from each reflection film layer for every frequency component λ1 to λn and distributes the components to a frequency detector 6. The detector 6 detects the presence or the absence of the corresponding frequency components #1 to λn and converts them into binary numbers. Thus, n bit information is simultaneously reproduced from the n reflection film layers of the disk 4.
