Abstract: An optical head device and an optical recording and reproducing apparatus using this optical head device, which can record information and reproduce the recorded information at any of optical recording media, such as a next generation optical recording medium, in which the wavelength of the light source is made to be shorter, the numerical aperture of the objective lens is made to be higher, and the thickness of the recording medium is made to be thinner, and conventional recording media of DVD and CD standards, are provided. A light having wavelength of 405 nm, emitted from one of optics, is inputted to an objective lens as a collimated light, and is focused on a disk having thickness of 0.1 mm. A light having wavelength of 650 nm, emitted from the other of optics, is inputted to the objective lens as a diverged light, and is focused on a disk having thickness of 0.6 nm.

Abstract: In order to interlock an electric contact within an insulating body for a plug-type connector, the invention provides integral clips that are axially spaced apart from one another and on the edges of which the electric contact can be interlocked within a through-opening on the mating side and on the connection side. The invention also proposes a method in which two mould cores that encompass one another and form the through-opening can be removed from the through-opening in opposite directions after the injection-moulding process.
Abstract: Controlled quantities of powdered medication are formed in controlled release packages using electrostating metering. Also provided are combination medication therapy delivery packages comprising two or more active pharmaceuticals segregated from one another in a single delivery package.
Abstract: In order to realize a connector housing (10) that is tightly sealed relative to the environment, there is provided a device for an axially slidable connector-ended cable (5) because a contact holder (20) connected to the connector-ended cable can be displaced by a defined axial distance (C) within the connector housing, wherein a constant pressure is exerted upon the contact holder (35) of a corresponding female connector (3) by means of an integrated pressure spring (40).
Abstract: An arc detector comprising a voltage generator for detecting a voltage and an integrator for integrating said voltage with respect to time and generating an output signal corresponding to said integration. The arc detector also includes a discharge controller for controlling said output signal of said integrator, an amplifier for amplifying said output signal from said integrator and outputting an amplified signal; and a comparator for comparing said amplified output signal to a reference voltage and generating a detection signal based on said comparison.
Abstract: A method and device for oxidization of materials in supercritical water. The method involves a) introducing a fluid containing water and an oxidizing agent in a ring-shaped area and through a first end of a substantially tube-shaped reactor comprising an external wall and an internal tube, b) heating the fluid in the ring-shaped area, c) introducing the heated fluid into the internal tube and simultaneously introducing material to be treated into said internal tube at a second end of the reactor, d) mixing the fluid and the material to be treated in a first portion of the internal tube, followed by cooling the obtained mixture in a second portion of the internal tube, and e) isobarically discharging the fluid/oxidized material from the internal tube of the reactor.
Abstract: In a plasma CVD apparatus, a plate formed with a plurality of perforated holes is arranged to separate a plasma generation region and a processing region. The aperture ratio of the perforated holes to the plate is not greater than five percent. Plasma including radicals and excited species is generated from an oxygen (O2) gas in the plasma generation region, then the radicals and excited species flow into the processing region through the perforated holes. A monosilane (SiH4) gas is also supplied into the processing region, but the backward flow of the monosilane gas into the plasma generation region is suppressed by the plate. In the processing region, the radicals and the excited species and the monosilane gas result in a gas phase reaction that yields the silicon dioxide film formed on the substrate or the wafer with high quality.

Abstract: A reliable and cost-efficient direct drive force feedback motor is suitable for joystick applications, allowing multiple degrees of output freedom, requiring no coil commutation, and permitting compact packaging. A multiple degree-of-freedom motor consistent with the invention comprises an output shaft, a stator, and a rotor. The stator comprises first and second lamination stacks, each lamination stack having an interior curved surface and a coil wound thereon, the lamination stacks being disposed adjacent the output shaft. The rotor is fixed to the output shaft and movably supported adjacent the stator with an air gap disposed between the rotor and the stator, the rotor including at least one magnet disposed thereon and being movable along the interior curved surface of the lamination stacks in directions defining at least first and second degrees of freedom.

Abstract: In a reflection type liquid crystal display device having a front light and a reflection type liquid crystal panel including a reflection electrode of uneven structure, average tilt angles of the uneven structure of the reflection electrode are changed to form a high directivity reflective region having a characteristic reflecting an incident light from the front light in a vertical direction and a wide viewing angle reflective region having a characteristic reflecting an outside light incident slantingly from the front in a vertical direction, thereby forming the high directivity reflective region and the wide viewing angle reflective region to be mixed in the reflection electrode in the same display device.
Abstract: A semiconductor device has an MIS (metal-insulating film-semiconductor) structure, and a film mainly containing Al, O, and N atoms is used on a semiconductor. Alternatively, a semiconductor device has an MIS structure, and a film mainly containing Al, O, and N atoms is provided as a gate insulating film on a channel region between a source and a drain. Characteristics required of a gate insulating film of a 0.05 ?m-gate-length-generation semiconductor transistor are satisfied. In particular, no fixed charge is included in the film, and impurity diffusion is reduced.
