Title: Optical head device
Inventor: TODE HIDEKAZU
IPC: G11B7/135
Filed: 1988-07-11
Abstract: PURPOSE:To obtain a high performance tracking error signal by forming an aperture of a grating area of a holographic element in the orthogonal direction to the direction of an information track to be an approximately oblong aperture shape as nearly equivalent to an outgoing beam diameter. CONSTITUTION:The grating area A of the holographic element 13 has the approximately oblong perture extending in the direction of (x), where a diameter of the aperture in the direction of (x) is equal to an effective aperture diameter of the outgoing beam 2 at the element 13. By such constitution, an optical disk 4 is irradiated by + or - first-order diffracted transmission light of an incident beam upon the area A with converged spots 10e and 10f. A spot 10a is set to be small enough to read satisfactorily information written on a track 9. A spot diameter in the direction of (x) is smaller than a space between the tracks 9 in the direction of (x), so that the spots 10e and 10f are capable of reading a signal traversing the track 9 in the direction of (x). Consequently, the tracking error can be obtained from an arithmetic output.

CONSTITUTION:A preform 4 (core material) of an elliptical cross-sectional shape is made to stick and grown at the lower end of a seed rod 1 by blowing control. In the above-mentioned method, various kinds of blowing control with raw material feeding parts 2 and 2' as centers are performed to provide deviation in the amount of sticking (growth) of the core material 3 and form the whole elliptical shape. Thereby, the core preform 4 consisting of elliptical cellular glass is obtained. In the process, e.g., speed change control over the relative rotational speed of the preform to the raw material feeding part and variable control of relative clearance between the preform and the raw material feeding part, are cited as the blowing control of the preform material 3. Blowing control in a relation inverse to that in the afore-mentioned core material 4 is carried out to blow the preform material 5 (clad material) onto the outer periphery of the core preform 4 to form a clad 6 into a circular shape in the outer layer.

The silicon oxide film is etched, and the surface of the semiconductor substrate 1 is exposed between an n<+> type polycrystalline silicon film 2 and the p<+> type polycrystalline silicon film 4. Said surface is etched by reactive ion etching, and grooves (or holes) 6 are formed. The width of each groove 6 is specified by a silicon oxide film obtained by the oxidation of the polycrystalline silicon film 2. Therefore, the width of the groove 6 can be made less than the minimum machining size. Thus the sizes of element isolation regions for isolating the well regions 2 and 4, i.e., the sizes occupied by silicon oxide films 7 and 9, can be reduced.

Title: Method for adding impurity
Inventor: HAYASHI HIROSHI
IPC: H01S5/00
Filed: 1980-12-03
Abstract: PURPOSE:To improve controllability for the addition of extremely small quantity of impurities into a growing layer, by forming an impurity adding layer having a constant concentration on the same crystal as a source crystal by liquid phase eqitaxial growing, measuring said addition layer, and obtaining the impurity material for the liquid phase epitaxial growing. CONSTITUTION:For example, a Te added grwoing layer which is grown on a GaAs substrate is employed as a raw material of Te, when Te doped GaAs or GaAlAs is grown by the liquid phase epitaxial growing. For example, the growing layer, wherein a mol ratio of Te is about 1.2X10<-2>, is grown on the GaAs substrate, and the substrate is removed by etching. For example, said product is used as an impurity raw material instead of metal Te. In this method, the quantity of the impurity raw material to be mixed in a solution can be increased by about 100 times when the growing layer having the desired carrier concentration is formed, and sufficient measuring accuracy can be obtained. Therefore, the addition of extremely small quantity of inpurities can be facilitated, and the control property can be improved.

A cover face part 45 is extended to an inner wheel 30, and its top end clogs the side part of a bearing body 15 through a minute cavity space (s). Hence, a strong sealing performance and a sealing performance never changed even if the both sides are reversed are obtained.
