摘要:
A negative feedback amplifier including, in an input stage, a common-emitter first transistor and a common-base second transistor for supplying a quiescent collector current (standing current) to the first transistor so that a sufficient standing current flows. A negative feedback circuit is connected between an output terminal of an output stage and the emitter of the second transistor, and a first limiter diode is parallely connected to the feedback circuit so as to prevent saturation of an NPN transistor of the output stage. The common-base transistor in the input stage makes it possible to select a high resistance resistor as a feedback resistor, thus enabling the standing current of the output stage to be reduced. A second limiter diode may be connected between the output terminal and the input terminal of the output stage.

A wiper apparatus comprises a wiper motor, a wiper switch, a moisture sensor for sensing presence of moisture, a vibration sensor for sensing a vibration caused by raindrops and a controller for actuating the wiper motor in accordance with output signals from the moisture sensor and the vibration sensor. The apparatus is free from the malfunction and works automatically by sensing even a drizzling rain.
摘要:
A pressure casting mold used to mold sanitary earthenware, including a porous layer composed mainly of resin material, a filler, a curing agent and water, the filler being formed of fibers and particulates of glass material, an average diameter of the fiber filler being 1 through 10 .mu.m, and an average length of the fibers being 20 through 100 .mu.m, and the diameter of the particulate filler being 10 through 50 .mu.m, thereby obtaining a porous layer which in use is hard to clog and is high in durability.
摘要:
A reduction gear in which an output shaft rotatably supports two planet gears engaging an internal gear fixed to a housing and a pinion gear at the end of the input shaft. The supports on the output shaft for the planet gears are circumferentially movable with respect to each other in order to eliminate back-lash.

A chuck for a robot or the like of a parallel opening/closing type. A piston is slidably supported in a cylinder, slidable in a first direction. A pair of slide pawls are slidably mounted so as to be movable in a second direction, perpendicular to the first direction, for performing opening/closing movement. The pawls are biased in the opening direction. A pair of action levers are rotatably supported on the cylinder, abutting an end of the piston and engaging with respective ones of the pawls. A pair of shafts are provided on the cylinder for guiding fulcrums of the action levers and the slide pawls. Each of the pawls has a reference portion projecting upwardly, two elongated holes, and a slot portion at a center portion thereof for receiving corresponding ones of the action levers. The reference portion of one of the slide pawls, the action levers, and the reference portion of the other one of the slide pawls are supported side by side on these shafts.

A 3D imaging device obtains a 3D image (3D video) that achieves an appropriate 3D effect and/or intended placement. The 3D imaging device estimates (calculates) an ideal disparity of a main subject based on a preset viewing environment (display condition) and a distance to the main subject, and obtains a disparity (an actual disparity) of the subject (main subject) actually occurring on a virtual screen. The 3D imaging device obtains a correction disparity using the ideal disparity and the actual disparity, and adds the calculated correction disparity to the 3D image (horizontally shifts the image) to perform appropriate disparity correction. The 3D imaging device obtains a 3D image (3D video) that achieves an appropriate 3D effect and/or intended placement without being affected by a disparity occurring in the horizontal direction caused by insufficient precision (in particular, insufficient optical precision).

Disclosed is a novel transdermally absorbable preparation which enables the efficient, stable and long-term administration of a drug to a living body. More specifically, the transdermally absorbable preparation comprises: a laminate comprising an outer film, a drug-containing layer and a support layer laminated in this order from the side to be contacted with the skin; and a fixing means for fixing the laminate on the skin. In the transdermally absorbable preparation, the outer film is a drug-permeable polymer film that can control the release of the drug into the skin and is provided as a surface of the laminate which is to be contact with the skin.

A distance measuring device using a multiple wave enables measurement of long distances with a high resolution and with a high precision by significantly reducing the circuit scale required for demultiplexing circuitry. A distance measuring device (1) includes an illumination unit (1) that illuminates using multiple modulated light having a plurality of frequencies satisfying a relationship in which one frequency is an even multiple of another frequency, a light receiving unit (20) that accumulates the charge of reflected light of the multiple modulated light into a plurality of accumulation units while switching an accumulation unit into which the charge is accumulated at a predetermined timing, and a distance calculation unit (30) that calculates a distance based on the charge.

A 3D image signal processing device performs a signal processing on at least one image signal of a first viewpoint signal as an image signal generated at a first viewpoint and a second viewpoint signal as an image signal generated at a second viewpoint different from the first viewpoint. The device includes an image processor that executes a predetermined image processing on at least one image signal of the first viewpoint signal and the second viewpoint signal, and a controller that controls the image processor. The controller controls the image processor to perform an feathering process on at least one image signal of the first viewpoint signal and the second viewpoint signal, the feathering process being a process for smoothing pixel values of pixels positioned on a boundary between an object included in the image represented by the at least one image signal and an image adjacent to the object.
