摘要： An optical waveguide chip including a core portion as an optical waveguide, a clad portion composed of a lower clad layer and an upper clad layer, and an optical fiber guide portion which is formed integrally with the clad portion for positioning a single-mode optical fiber which is to be connected with the core portion. Each portion of the optical waveguide chip is formed by creating a layer of a radiation-sensitive polysiloxane composition by photolithography. At least two kinds of radiation-sensitive polysiloxane compositions are used so that the core portion has a higher refractive index than the clad portion.

摘要： A magnetic recording and/or reproducing apparatus for use with a tape cassette. A pair of tape loading posts are moved respectively by first and second drive gears to draw a portion of a magnetic tape out of the tape cassette to wrap the magnetic tape portion about a head drum. The tape loading posts are drivingly connected respectively to the first and second drive gears through respective lost-motion mechanisms such that subsequent angular movements of the respective first and second drive gears after movement of the tape loading posts to their respective tape loading positions are prevented from being transmitted respectively to the tape loading posts. The first drive gear is provided in its outer periphery with a cut-out. A tape loading gear is in facing relation to the cut-out in the first drive gear until the tape cassette moves to its loading position. After movement of the tape cassette to its loading position, the first drive gear is angularly moved slightly so that it is brought into mesh with the tape loading gear and is driven thereby for angular movement in its tape loading direction.

摘要： A movable guide for receiving a caddy is provided movably in the loading and unloading directions on a main chassis. The movable guide is moved by a drive mechanism from an eject position to a disk drive position. An arrangement is made so that by an action of front and rear guide pins engaged in front and rear cam slits of the main chassis, when the movable guide is at the eject position, a turntable of a traverse unit disposed below the main chassis is spaced by a predetermined distance from a disk and, as the movable guide is moved in the loading direction, approaches gradually to the disk and, when the movable guide reaches the disk drive position, the turntable is attracted to the disk. The turntable approaches the disk upwardly relatively from beneath the disk and is attracted smoothly to the disk by a series of continuous operation.

摘要翻译：一种与磁带盒一起使用的磁记录和/或再现装置。一对带装载柱分别由第一和第二驱动齿轮移动以将磁带的一部分从带盒中拉出以将磁带部分包围在磁头鼓上。磁带装载柱通过相应的丢失运动机构分别驱动地连接到第一和第二驱动齿轮，从而防止相应的第一和第二驱动齿轮在磁带装载柱移动到其相应磁带装载位置之后的角度运动。分别传送到磁带装载柱。第一驱动齿轮在其外周设有切口。磁带加载齿轮与第一驱动齿轮中的切口面对面，直到带盒移动到其装载位置。在磁带盒移动到其装载位置之后，第一驱动齿轮稍微有角度地移动，使其与磁带加载齿轮啮合并由此驱动，从而在磁带装载方向上进行角度运动。

摘要： A first adjusting base made of a leaf spring material is supported on a holder in such a manner that the first adjusting base crosses the moving direction of the holder and is slightly pivotable about a first pivot axis which is parallel to a disk surface. A second adjusting base made of a leaf spring material is supported on the first adjusting base in such a manner that the second adjusting base crosses the first pivot axis and is slightly pivotable about a second pivot axis. The first and second adjusting bases are biased in a slightly pivoting direction by their own elasticity and, by turning screws which restrict the biasing, the first and second bases are pivoted to adjust the direction of an optical axis of a pickup head. Shaking of the pickup head is prevented and shock to the pickup head is absorbed by elasticity of the first and second adjusting bases whereby the device can be made compact and light.
摘要翻译：由板簧材料制成的第一调节基座以这样的方式被支撑在保持器上，使得第一调节基座跨过保持器的移动方向，并且能够绕平行于盘表面的第一枢转轴线稍微地枢转。由板簧材料制成的第二调节基座以这样的方式支撑在第一调节基座上，使得第二调节基座与第一枢转轴线相交并且可围绕第二枢转轴线稍微转动。第一调节基座和第二调节基座通过其自身的弹性以稍微的枢转方向偏置，并且通过转动限制偏置的螺钉，第一和第二基座枢转以调节拾取头的光轴的方向。防止拾取头的晃动，并且通过第一和第二调节基座的弹性来吸收对拾取头的冲击，由此可使装置紧凑且轻便。
