    摘要: A speaker apparatus in which the acoustic sound is radiated by flexural oscillations of a diaphragm in the form of a panel having a substantially flat surface. The speaker apparatus includes a panel-shaped diaphragm the outer rim of which can be oscillated substantially freely at least in the direction along the diaphragm thickness and at least one driver unit constituting an oscillation source secured to the diaphragm surface for imparting oscillations to the diaphragm. The diaphragm is set into flexural oscillations by oscillations applied from the driver unit driven on the basis of the playback input signal. By flexurally oscillating the diaphragm to radiate the acoustic sound, optimum frequency response characteristics can be obtained over a wide frequency range from the low to high frequency range. Moreover, the acoustic sound of optimum sound quality may be radiated in a state of minimum sound pressure level fluctuations over a frequency range from the low to high frequency range.

    摘要: A driving mechanism has a base member, a moving member, a rotatable first idler, a rotatable second idler, and a rotating member disposed between the first and second idlers. A power-transmission belt is disposed such that it contacts with the first idler, passes between the first idler and the rotating member, contacts with the rotating member, passes between the rotating member and the second idler and contacts with the second idler. A part of the belt contacts with the base member by the first idler and another part of the belt also contacts with the base member by the second idler. With this mechanism, rotational movement is converted to linear movement, and vice versa.

    摘要: A kinetic energy regenerating device utilizes the principle of perfectly elastic collision through an elastic member between a rotating body on the driving side and a flywheel to regenerate kinetic energy at a high regenerating efficiency. The kinetic energy regenerating device (1) comprises a main shaft (2) connected to the output shaft of a driving arrangement, a main disk (5) fixedly mounted on the main shaft (2), a first rotor (6) supported on the main shaft (2) for rotation relative to the main shaft (2), a flywheel (10) supported on the main shaft (2) for rotation relative to the main shaft (2), a first clutch (9) for engaging the main disk (5) and the first rotor (6) and disengaging the same from each other, and a torsion coil spring (16) elastically interlocking the first rotor (6) and the flywheel (10). The rotational energy of the main disk (5) is transmitted through the first clutch (9) to the first rotor (6) to rotate the flywheel (10) and, at the same time, to twist the torsion coil spring (16).

    摘要: A holderless hose clip, primarily for use in preventing piping hoses from falling off of connecting pipes in automotive vehicles, includes a clip body formed of a leaf spring having the shape of an annular band and which clamps the hose when released from a spread-diameter state to assume a free state. A pair of grip strips are formed by bending the ends of the clip body, respectively. An engagement claw and an engagement recess are formed on the respective grip strips to secure the grip strips to each other when the grip strips are gripped, so that the clip body is held in the spread-diameter state. The engagement claw has a guide face for guiding the grip strips axially of the clip body when the grip strips are gripped whereupon the engagement claw is received in the recess. In an alternative form of the hose clip, an opening is formed between the grip strips and a tool can be inserted into the opening while the hose clip is in the spread-diameter state to move the grip strips radially of the clip body and thereby release the clip body from the spread-diameter state.

    摘要: Disclosed is an apparatus and method for controlling switching elements (51-56) of a PWM-controlled value type inverter by a software program using a microcomputer (10). The control apparatus of the present invention produces a switching element control signal (an on/off signal) according to the following steps. When a control command value commanding the output of the inverter is determined, a control mode corresponding to the commanded output value is selected from among a plurality of control modes (M1-M6) previously contained in a table to determine the switching elements to which the control signal is applied and the order of controlling the switching elements. Further, on the basis of the control command value, the difference between a modulation signal and a predetermined reference value is computed for each phase to determine the timing of controlling the switching elements. The unit control period of each control mode is divided into halves, and the switching element control timing is determined in each of the halves of the unit control period. The control signal is produced on the basis of the combination of the selected control mode and the determined control timing.
