    • In a roll type straightener, a barrel assembly including a pair of rolls (3, 3'), tightening male and female screws (5, 4), displacement male and female screws (14, 13) is mounted on a main shaft (8). The periphery of the respective female screws (4, 13) have a plurality of notches (22), with which pawls (18a, 19a) of levers (18, 19) are engageable for preventing the female screws (4, 13) from rotation with the main shaft (8) by a drive source. Upon the adjustment of barrel width, the pawl is selectively engaged with the notch (22) of the tightening female screw (4) or both female screws (4, 13), so that the female screws drive the mating male screws (5, 14) in the axial direction to displace one of the rolls (3') to a predetermined position, as the main shaft (8) rotates. The operation sequence is controlled in a fully automatic manner by a controller (23) while monitoring the rotation of the main shaft (8) by a detector (20).
    • 在辊式矫直机中,包括一对辊(3,3'),紧固公螺纹和内螺纹(4,5)的筒组件,位移公螺纹和内螺纹(14,13)安装在主轴(8)上 )。 各个内螺纹(4,13)的周边具有多个切口(22),与此相对应的爪(18a,19a)的爪(18a,19a)能够接合,以防止内螺纹(4,13)旋转 主轴(8)通过驱动源。 在调节镜筒宽度时,棘爪选择性地与紧固内螺纹(4)的凹口(22)或两个内螺纹(4,13)接合,使得内螺纹驱动配合的外螺纹(5,14) )沿主轴(8)旋转,以将一个辊(3')移动到预定位置。 在通过检测器(20)监视主轴(8)的旋转的同时,通过控制器(23)以完全自动的方式控制操作顺序。

    • A split type optical pick-up device suitable for use in an optical disc memory system has a two-part structure: stationary and movable optical systems which are provided separately. The stationary optical system includes a semiconductor laser for emitting a laser beam which is received by a deflecting member of the movable optical system. The thus deflected laser beam is focused onto an optical disc by an objective lens. The light reflecting from the optical disc passes through the objective lens in the reversed direction and also through the deflecting member to impinge upon a tracking error detector which is also provided in the movable optical system. Because of the provision of the tracking error detector in the movable optical system, there will be produced no offset in a tracking signal generated by the tracking error detector.
    • 适用于光盘存储器系统的分割型光学拾取装置具有两部分结构:分开设置的固定和可移动光学系统。 固定光学系统包括用于发射由可移动光学系统的偏转构件接收的激光束的半导体激光器。 这样偏转的激光束被物镜聚焦在光盘上。 从光盘反射的光沿相反方向穿过物镜并且还穿过偏转构件以撞击也设置在可移动光学系统中的跟踪误差检测器。 由于在可移动光学系统中提供了跟踪误差检测器,所以在由跟踪误差检测器产生的跟踪信号中将不产生偏移。

The light reflected from the optical disc passes through the objective lens in the reverse direction and also through the deflecting member to impinge upon a tracking error detector which is also provided in the movable optical system. The deflecting member has differnt rates of transmission for p and s polarized light for the light reflected from the optical disc such that the s polarized light is reflected toward the stationary optical system as much as possible so as not to waste the s polarized light, which defines a component of an information signal to be reproduced in the stationary optical system. Because of the provision of the tracking error detector in the movable optical system, there will be produced no offset in a tracking signal generated by the tracking error detector, and since the deflecting member reflects the s polarized light as much as possible, there is obtained an enhanced S/N ratio.

    • A heating wire is wound around a casing within which a sensor body is placed. Thermo-sensitive switch means is connected to the heating wire, which is responsive to the temperature within the casing to control the rate at which electric current is supplied to the heating wire so as to keep the temperature at a constant value. The casing may be placed within an airtight housing which is made of an insulating material. A further heating wire may be arranged on the inner wall of the airtight housing, which is controlled by further thermo-sensitive switch means so as to keep the temperature within the housing at a constant value.

    • A medium judgment program is recorded on an information recording medium. The program causes a computer to judge whether the medium is authorized. The judgment may be based on information on a unique value preformed in the medium in regard to each of the media. If the computer determines that the information recording medium is right or authorized, the program permits the computer to reproduce a main program. The main program is different than the medium judgment program. If the computer determines that the information recording medium is wrong or unauthorized, the computer is prohibited from reproducing the main program.
