摘要： PURPOSE:To enable a good tracking control that is mighty against both flaw on a disk and external impact by decreasing a gain of a tracking servo control in the case of a flaw on the disk and increasing the gain in the case of an external impact. CONSTITUTION:In the case of a flaw on the disk 1, a preformat signal S31a and a tracking error signal S32a are both fluctuated. In the case of an external impact, the signal 32a is generated as an error amt. When the flaw is found on the disk 1 by comparing of comparators 61 and 62, a 1st deciding signal S60a of the disk 1 is outputted by a flaw/impact deciding circuit 60 of a drop- out detection processing part 50, and when the external impact is found, a 2nd deciding signal S60b of the disk 1 is outputted. When the signal 60a is outputted, a tracking error signal S32a-1 at a low level is outputted from a gain variable circuit 70, and is given to a servo control part 42. On the other hand, when the signal S60b is outputted, the signal S32a-1 at a high level is outputted from the circuit 70, and is given to the control part 42.

摘要： PURPOSE:To continuously restart control with a tracking signal by detecting the runaway of an optical head and stopping the driving of the optical head for a prescribed time when operation is moved from access operation to tracking operation. CONSTITUTION:When a counter 5 finished the counting of a track moving number, which is a purpose, and an access is ended, a selecting signal (a) of switching control 10 goes to '1' and a drive switching part 9 selects a tracking signal TS. At such a time, when an optical head 1 shown in a position signal S is not enough decelerated, a runaway detecting part 11 causes a runaway detecting signal E to '1' and runaway is detected. According to the signal E, a drive control part 12 sends a stopping signal (b) to a driving part 2 and the driving part 2 stops operation. Then, a track servo is turned off. The head 1 goes to stopping operation and the track servo is turned on again and track- positioned. Thus, the runaway is prevented.

摘要： PURPOSE:To make it possible to apply direct printing to printing paper by an ink stylus, by projecting the other end of the ink stylus part of an ink lead-out means only by a minute length from the surface of an ink lead out means support at the time of non-printing. CONSTITUTION:An ink stylus part 1 consists of an engineering resin molded body and a metal fine tube and one end thereof forms an ink lead out part in integral relation to a base stand part 2 and the other end thereof is projected from the flat surface of an ink lead out means support 3 at the time of non- printing so as to obtain an exposed part 1c in a minute projection amount. The ink lead out from the ink stylus part 1 is supplied by the capillary phenomenon of the ink guide body with a desired void ratio comprising fibers and the ink occlusion body 6 in a flexible pipe 9 and the stylus part 1 is impacted to paper by the motion to the side of platen through an elastic plate 4 to form an ink picture element. At this time, the ink stylus part 1 is moved to the direction of the occlusion body 6 while guided in the support 3 by pressing force and embedded thereinto.

摘要： PURPOSE:To enable to drive a printing hammer by a low voltage and to obtain a large displacement, by a method wherein a plurality of ceramic sheets are laminated, and electrodes are provided on both sides of each of the ceramic sheets so that the electrode provided between adjacent ones of the sheets functions as a common electrode for the adjacent sheets, thereby constituting a multilayer construction. CONSTITUTION:A plurality of the ceramic sheets 7 are laminated to constitute a multilayer construction, electrodes 8 of appropriate pattern are provided at predetermined positions of both sides of each of the ceramic sheets 7, and the electrode 8 provided between adjacent ones of the sheets 7 is used as a common electrode for the adjacent sheets 7. The directions of polarization of the electrodes 8 are so set that they are opposite for the adjacent ceramic sheets 7, as indicated by arrows P. Accordingly, since a bimorph-type printing hammer is provided by utilizing the transverse effect of mechanical strains of a piezoelectric ceramic, there is no need for a separate magnifying mechanism. In addition, since the electrodes are provided on both sides of each of the ceramic sheets constituting the piezoelectric ceramic, the hammer can be driven by a low voltage.
摘要翻译：目的：为了能够以低电压驱动打印锤并获得大的位移，通过层叠多个陶瓷片的方法，并且在每个陶瓷片的两侧设置电极，使得提供电极在相邻的片之间，作为相邻片的公共电极，由此构成多层结构。构成：多个陶瓷片7被层压以构成多层结构，在每个陶瓷片7的两侧的预定位置处设置适当图案的电极8，并且设置在相邻的片7之间的电极8 被用作相邻片材7的公共电极。如箭头P所示，电极8的极化方向被设定为相邻的陶瓷片材7相反。因此，由于双压电晶片型打印锤是通过利用压电陶瓷的机械应变的横向效应提供，不需要单独的放大机构。此外，由于电极设置在构成压电陶瓷的每个陶瓷片的两侧，因此锤可以由低电压驱动。

摘要： PURPOSE:To reduce high-frequency vibration and vertical and horizontal vibration by a method wherein a prescribed inertia mass which has a printing wire is mounted and fixed on a movable plate provided to the center of an elastic plate and a piezo-porcelain plate, which is divided into two and has electrode layers on its front and back surfaces, is solidly jointed with the elastic plate. CONSTITUTION:When an inertia mass 10 returns to a balancing position at a high speed, it is given a repulsion force from the whole surface contacting with a base plate 19 so that the movement of the inertia mass 10 becomes rebounding motion with straight component and rotation component. In order to reduce this phenomenon, a cut slot 24 is provided to an upper plate 23 which is also used as a clamp for printing hammer to form a pivot 25, which is provided to a suitable position corresponding to the position of a pivot 21 of the base plate 19. With this composition, the straight movement of the inertia mass 10 is completely restrained and the rebounding motion due to the remaining rotation component force is also reduced to be almost negligible.
摘要翻译：目的：通过以下方法减少高频振动和垂直和水平振动：其中具有印刷线的规定惯性质量块被安装并固定在设置在弹性板的中心的可移动板和压电陶瓷板上，被分为两部分，其前表面和后表面具有电极层，与弹性板牢固地接合。构成：当惯性质量块10以高速返回到平衡位置时，从与基板19接触的整个表面获得排斥力，使得惯性质量块10的运动成为具有直的分量和旋转的回弹运动零件。为了减少这种现象，切割槽24被设置到上板23，上板23也用作用于打印锤的夹具以形成枢轴25，枢轴25设置在对应于枢轴21的枢轴21的位置的合适位置通过该组成，惯性物料10的直线运动被完全抑制，并且由于剩余的旋转分力而导致的回弹运动也降低到几乎可以忽略不计。
