摘要： PROBLEM TO BE SOLVED: To provide a disk access device which is capable of stably executing the pull in of a tracking servo control even in an information signal of a low frequency of an information recording disk. SOLUTION: The low frequency gain of a phase compensation means (65) of a tracking servo control loop is raised in order to improve the follow-up accuracy of the tracking servo control by accompanying high-speed rotation of a recording disk. At this time, a tracking error signal (TE) is prevented from passing a low-frequency compensation section (61) by a switch (60) and a bypass signal route (65) in tracking servo control pull in. As a result, a large gain is not imparted to the tracking error signal and the delay of the phase is eliminated and therefore the drastic deviation of the phase relation between the output of the phase compensation means (65) and the envelope detection signal of the signal (RF) outputted from a photo-electric conversion circuit from a desirable state may be prohibited and the stable formation of a brake signal (BSIG) is made possible.

摘要： PROBLEM TO BE SOLVED: To reduce the probability of an error uncorrectable to a read signal even when a disk state is bad without making a sacrifice of the transfer speed of data. SOLUTION: In the recorded information reproducing device reading information from a running surface of the disk 1, performing error detection and correction processing for the information, reproducing the recorded information and sending out the information, a control means 11 switching a reproducing mode to a standard speed reproducing mode according to an uncorrectable state caused in a four-fold speed reproducing mode, and performing again reproducing for the error uncorrectable information is adopted. In the again reproducing processing in the standard speed reproducing mode, the matter making a signal read speed 1/4 improves the error uncorrectable due to a random error since the C/N of a high frequency signal RF, etc., is improved by 6dB.

摘要： PURPOSE:To obtain a moving body radio for securing a function of electronic parts, improving the housing space factor, and promoting a waterproof effect and a cost reduction. CONSTITUTION:The periphery of electronic parts 9 mounted on a circuit board 8 is protected and coated with a potting synthetic resin 10, fixed into a die cavity, and by injecting a synthetic resin, a housing 1 and the circuit board 8 are formed integrally. Thereafter, by using hard and soft synthetic resins in different processes, a dial unit part 2 formed by a two-stage forming method is fixed to an integral formed part and the moving body radio terminal is manufactured. In such a way, since the circuit board 8 on which electronic parts are mounted and the housing 1 are formed integrally, the capacity efficiency is improved and the waterproof effect is promoted. Also, since an assembling work can be curtailed, the cost reduction is realized. Moreover, since the electronic parts are protected and coated, at the time of integral forming and at the time thermal shock test, such a problem as peeling-off, etc., is not generated.

摘要： PURPOSE:To reduce the wiring space and prevent the interference between wirings by arranging terminal boards on the rear sides of a plurality of units in a housing, dividing the space formed on the rear sides of the units in the direction of the depth, and arranging the wirings while classifying according to the function. CONSTITUTION:A plurality of units 2 are kept in a housing vertically. The terminal board 3 on the rear side of each unit 2 has a connecting device 5 for an outside line cable 4 and a connecting device 7 for the connecting cables 6 between the units 2. Wiring space is formed in the rear of each unit 2, and divided into two in the direction of its depth. The cables 6 between the units 2 are arranged nearer to the terminal boards 3, and the outside line cable 4 is arranged and wired in the rear while being separated from the cables 6. Besides, a plurality of cable fixing and supporting devices 9 are provided between a right and left side-boards not shown in order to bind the rising part of the cable 4. And, this reduces the wiring space, prevents the inductive interference between the wirings, and facilitates the maintenance and inspection.

摘要： PURPOSE:To reduce the number of man-hours by making the shape of development diagram excluding the surface which is vertical to a device while being mounted to the device to be in a shape matching the direction of move of a processing machine. CONSTITUTION:While mounting a mounting part 4 to a device etc., the surface which is parallel to the device is angled to the same angle theta as a slant part 2. Thus. the shape of parts development diagram before a parts 1 is subjected to bending machining, is at right angle to two directions of X and Y excluding the surface which is vertical to the device while being mounted to the device, etc., matching the move direction of a standard press processing machine or a numeric control processing machine. Therefore, machining in standard X and Y directional move can be made and the number of machining man-hours can be reduced.
