A mat (1a) for an acoustic apparatus, wherein a plurality of granular bodies (2a) of an inexpensive silica gel are disposed in the state of single layer. When the mat (1a) is laid under the acoustic apparatus, the upper end parts of the granular bodies (2a) are brought into point-contact with the bottom surface of the acoustic apparatus, and the lower end parts of the granular bodies (2a) are brought into point-contact with a floor surface thereunder. Accordingly, the reflection of vibration can be reduced by minimizing the contact area of the mat (1a) with the acoustic apparatus, and vibration on the upper end part side of the granular bodies directly transmitted to the mat (1a) and vibration indirectly transmitted to the mat (1a) after being reflected on the lower end part side of the granular bodies can be very rapidly diffused in the air.

For a balance adjustment due to a reduction in size and weight of an actuator, an arm portion, an axis attaching portion, and a coil supporting portion are arranged so that the centers of gravity on the coil side are located on a straight line connecting a rotational center and the center of gravity on the head side. Further, the improvement of an assembling efficiency of a VCM, an increase in torque, a one-touch fixing of an FPC connecting band, a noise prevention of a read pattern, and an insulation between the base and cover due to a bias of an MR read head are accomplished. A sector mark is detected by comparing a peak detection pulse and its reference polarity signal. A redundancy is provided to a reference detection polarity signal so that a read signal can be detected even if any one of the read signals of the sector marks is dropped out. A gray code detecting section for recognizing a cylinder address also detects on the basis of a peak detection pulse and a polarity signal due to the reading of a gray code. A memory space to store a program is divided into an ROM space of a small electric power consumption and an RAM space of a large electric power consumption and stores each peculiar program. When the CPU doesn't execute a program in the RAM space, the execution of an idle program in the ROM space is allocated, thereby reducing an electric power consumption in an idle state by using an ROM.

摘要:
Sytème de modification de disquettes souples, par exemple de taille 8'' ou 5 1/4'', utilisées comme support de logiciels ordinateurs et équipements périphériques. Le système permet de modifier la capacité d'origine de stockage d'informations sur les surfaces magnétiques, ou disques. La modification est obtenue en créant des trous ou perforations spéciaux pour le décodage optique et magnétique. Ces nouveaux trous sont percés symétriquement des deux côtés de la pochette noire de protection du disque ou sur son (ses) bord(s). Le système utilise un gabarit combiné (1) qui est creux et se compose de deux surfaces rectangulaires identiques incomplètes, fermées en (7a), (7b) et ouvertes en (3a), (3b). Chaque surface est pourvue de demi-cercles positionnés (1a), (1b) et d'ouvertures en U traversant les deux surfaces (1c), (1d), (1e), (1f). Un outil perforateur (9) à angle alpha se compose de deux mâchoires tranchantes (10a), (10b) qui, en position fermée, rentrent l'une dans l'autre, formant un espace interne en U et reliées aux poignées (11a), (11b). Une disquette souple peut être introduite dant le gabarit ou guide (1) et après l'alignement du coin (8a) avec le coin (8b) et le positionnement des zones (1a) avec (5a) ou (1b) avec (5b), la partie avant de l'outil perforateur (9a) de (9), peut être positionnée de manière que le serrage des mâchoires tranchantes (10a), (10b) provoque le découpage d'un trou, par ex. (2b) sur la pochette de la disquette (2a); la forme du trou est déterminée par exemple par le contour d'une ouverture en U, par ex. (1c), du gabarit ou guidage (1).

The present invention provides a liquid crystal display device with a built-in disk device by adopting an arrangement of the disk device and the substrate designed so as to be able to reduce the size and thickness of the liquid crystal display device and share the substrate among liquid crystal display devices having different screen sizes. In a 20-inch LCD 50, amain control substrate 14 is disposed substantially at the center of the lower part, substantially in parallel to an LCD module, a disk device 11 is disposed at the top on the left side and a disk device control substrate 12 is disposed alongside the disk device 11 so as to be substantially horizontal to the disk device 11 and a power supply circuit substrate 51 is disposed at the top on the right side so that it is possible to use the same disk device 11, the disk device control substrate 12 and the main control substrate 14 as those of a 14-inch LCD.

For a balance adjustment due to a reduction in size and weight of an actuator, an arm portion, an axis attaching portion, and a coil supporting portion are arranged so that the centers of gravity on the coil side are located on a straight line connecting a rotational center and the center of gravity on the head side. Further, the improvement of an assembling efficiency of a VCM, an increase in torque, a one-touch fixing of an FPC connecting band, a noise prevention of a read pattern, and an insulation between the base and cover due to a bias of an MR read head are accomplished. A sector mark is detected by comparing a peak detection pulse and its reference polarity signal. A redundancy is provided to a reference detection polarity signal so that a read signal can be detected even if any one of the read signals of the sector marks is dropped out. A gray code detecting section for recognizing a cylinder address also detects on the basis of a peak detection pulse and a polarity signal due to the reading of a gray code. A memory space to store a program is divided into an ROM space of a small electric power consumption and an RAM space of a large electric power consumption and stores each peculiar program. When the CPU doesn't execute a program in the RAM space, the execution of an idle program in the ROM space is allocated, thereby reducing an electric power consumption in an idle state by using an ROM.
