Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To improve the quality of a reproduced sound by delaying the output of a musical sound signal from a musical sound signal generating means to another speaker. SOLUTION: One of branched signals of a musical sound signal SL for a left speaker is outputted from the tweeter of the left speaker as a musical sound signal SLH for the tweeter and the other musical sound signal SL is delayed by a specific delay value D through a delay circuit 26L and then outputted from the woofer of the left speaker. Similarly, one of branched signals of a musical sound signal SR for a right speaker is outputted as a musical sound signal SRH as it is and reproduced by the tweeter of the right speaker, and the other is delayed by the same delay value D through a delay circuit 26R, outputted as a musical sound signal SRL, and reproduced by the woofer of the left speaker.

Title: Magnetic disk device
Inventor: HOSHI AKIO
IPC: G11B21/12
Filed: 1985-08-16
Abstract: PURPOSE:To decrease the deterioration of a head and a disk by providing a regulating member energized in the direction to unload a head arm and a cam mechanism to shift the regulating member in the head loading direction in resisting the energizing force. CONSTITUTION:When a button 3 is pushed while the magnetic head is not contacted with the magnetic disk, a sliding lever 5 is shifted in the B direction of an arrow. As the result, a clamping lever 29 and a clamping arm are descended in a single body and the centering of the magnetic disk is executed. When the button 3 is further pushed in such a condition, the magnetic disk is completely clamped. Simultaneously, since a roller 6 is shifted from the lower side of a protruding piece 20a to the lower side of a bending part 20, a head load lever 17 is turned in the C direction of an arrow with a shaft 18 as a center. As the result, the head arm is pushed by the protruding piece 25 in the lower direction and the magnetic head is contacted with the magnetic disk. Thus, after the centering of the roller 6 and the head lock is executed, the magnetic head is contacted with the magnetic disk. Since the roller 6 and the head load lever 17 are operated on the slope surface, the contacting of the head and the disk comes to be bufferring.

Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To effectively perform electrification of dust and decomposition of odor, respectively, by increasing the number of needle tips in a needle electrode so as to enlarge a corona discharge space by forming the needle electrode constituting a corona discharge electrode by superposing a pair of plate-shaped members having a plurality of protrusions made by press working. SOLUTION: An application of a voltage between electrodes by a high voltage power source 4 generates radicals uniformly between a needle electrode 1 and a pair of opposing left/right electrodes 2, 3. In this case, the needle electrode 1 is formed by superposing a pair of left/right plate-shaped members 1b having a plurality of protrusions 1a provided by press working. Each protrusion 1a of the needle electrode 1 is disposed at an equal distance from the respective opposing left/right electrodes and uniform discharge is carried out between them. Therefore, since electrons and radicals are generated uniformly between the electrodes 1-3, electrification of dust and deodorization of odor are effectively performed. That is, the number of needle tips is increased without increasing the size of the needle electrode 1 and a discharge space between the electrodes 1-3 is enlarged.
