摘要： A converter that records or reproduces information to or from a recording medium while making a movement relative to the recording medium is mounted on a slider. The slider has at least a pair of openings on a side face thereof, and airflow generated by the movement relative to the recording medium flows in via one of the paired openings, passes in a vicinity of a surface of the converter other than a surface thereof facing the recording medium, and thereafter flows out via the other one of the paired openings. With this, the ability to cool the converter is improved.

摘要： An optical disc clamp mechanism that is capable of selectively playing back either of a compact disc or a mini disc. The clamp mechanism includes a circular disc receiving section for contacting a reference surface of either of the compact disc or the mini disc and further includes a magnetic clamp unit for clamping the mini disc by magnetic attraction with a magnetically attractable member of the mini disc. A first conical or spherical taper cone portion for engaging the center hole of the mini disc is mounted to the disc receiving section and a second conical or spherical taper cone portion for engaging the center hole of the compact disc is mounted to the disc receiving section. The first taper cone portion is located inwardly of the second taper cone portion and protrudes from the second taper cone portion in the axial direction. The magnetic clamp unit further includes a stopper element for preventing detachment of the first and second taper cone portions from the disc receiving section. Accordingly, the optical disc clamp mechanism independently affects the centering of a mini disc and a compact disc to allow either of the discs to be centered.

摘要： Disclosed is a semiconductor device using a polycrystalline compound semiconductor with a low resistance as a low resistance layer, and its fabrication method. The above polycrystalline compound semiconductor layer is doped with C or Be as impurities in a large amount, and is extremely low in resistance. The polycrystalline compound semiconductor layer is formed by either of a molecular beam epitaxy method, an organometallic vapor phase epitaxy method and an organometallic molecular beam epitaxy method under the condition that a substrate temperature is 450.degree. C. or less and the ratio of partial pressure of a V-group element to a III-group element is 50 or more. In the case that the above polycrystaline compound semiconductor layer with a low resistance is used as an extrinsic base region of an heterojunction bipolar transistor, since the extrinsic base region can be formed on a dielectric film formed on a collector, it is possible to reduce the base-collector capacitance, and hence to enhance the operational speed of the heterojunction bipolar transistor.

摘要： An optical head is mounted in an optical disk apparatus that optically records or reproduces information on or from an information recording medium having a magnetooptical effect. The optical head includes a laser diode for emitting a P-polarized beam and a first hologram element on which the P-polarized beam is incident and which diffracts the P-polarized beam more in zeroth order than in higher orders but diffracts an S-polarized beam perpendicular to the P-polarized beam more in higher orders than in zeroth order. The zeroth order P-polarized beam emitted from the laser diode is focused on the information recording medium by the first hologram element or an objective lens interposed between the first hologram element and the information recording medium. One or more second hologram elements are placed between the first hologram element and the laser diode and split a beam reflected from the information recording medium and then diffracted by the first hologram element into beams having respective planes of polarization perpendicular to each other. A plurality of optical detectors for detecting the beams transmitted through the second hologram elements are disposed in line with the laser diode.

摘要： An impurity diffusion method which can control a surface atomic concentration from a low to a high surface atomic concentration with a good uniformity is provided. Natural oxide is removed from the surface of a semiconductor substrate with a deoxidizing atmosphere gas as a diffusion atmosphere gas in advance, and then an impurity gas is passed thereto, while passing the deoxidizing atmosphere gas thereto, thereby conducting the diffusion. Flow rate or concentration of impurity of the impurity gas is so set that the impurity atomic concentration of the diffusion layer can be controlled by the flow rate or the concentration of impurity of the impurity gas. The impurity atomic concentration of the diffusion layer can be controlled by adjusting the flow rate or concentration of impurity of the impurity gas, and a diffusion layer having a low impurity atomic concentration can be formed. A shallow junction having a depth of not more than 50 nm can be formed.

Each of the elastic members has one end fixed to the base member. The other end of each of two of the elastic members is fixed to a distal portion of a first leg of the lens holder adjacent the base member. The other end of each of the other two elastic members is fixed to a proximal portion of a second leg of the lens holder remote from the base member.
