Abstract:
A bathyphotometer system is described for detecting photoluminescent signals excited by a grid disposed in a marine vehicle. The system uses photodiodes to convert the optical signals into electrical signals which are sampled, integrated and coupled to output terminals for transmission to a surface host vehicle. In one embodiment the signals are digitized and encoded as FSK tones for transmission to the surface host vehicle.
Abstract:
An optical integrated circuit element package comprises a lead frame, a chip, a wall, and a transparent cover. The lead frame has a plurality of leads substantially coplanar and defining a central region, and a die pad is disposed on the central region. The chip is disposed on the die pad and has an optical integrated circuit element and a plurality of pads which are electrically connected to the plurality of leads by a plurality of bonding wires. The height of the wall is higher than the chip and the plurality of bonding wires, and the wall has an extending portion hermetically extending between the die pad and the plurality of leads. The extending portion is substantially coplanar with the leads, and the plurality of leads are exposed out of the lower surface of the extending portion. The transparent cover hermetically covers the wall.
Abstract:
A diagonal inner-face curved portion is formed on an inner face of a diagonal portion of a pyramid-shaped yoke portion. The diagonal inner-face curved portion is formed to make at least one of partially inner-face curved portions at the major axis side and the minor axis side of the diagonal axis swell to the outward side. The partially inner-face curved portions at the major axis side and the minor axis side are formed by circular arced portions with different radii to each other.
Abstract:
A self contained sensing apparatus includes a housing establishing an interior compartment, the housing having a maximum thickness which is less than the size of a gate opening of a semiconductor wafer processing chamber for inserting the housing into the semiconductor wafer processing chamber for sensing a parameter. The housing includes a window extending through a principal housing surface. A sensor is provided within the housing and generally aligned with the window for sensing at least one parameter. A transmitter is provided within the housing and coupled with the sensor for receiving signals representative of the sensed parameter and transmitting the signals out of the housing.
Abstract:
The invention includes at least one swingable elastic locking bar mounted on the chassis of the scanner, and the end of the elastic locking bar is provided with a contact member having a low friction coefficient, and let the contact member on the elastic locking bar contact the top cover of the frame body of the scanner. Thus, the chassis may be rigidly rested on the top cover or on the glass mounted on the top cover to move, thereby providing a good scanning effect of an arbitrary angle. The swingable action of the elastic locking bar may efficiently absorb the tolerance produced during fabrication and assembly of the top cover and the bottom housing of the frame body of the scanner, thereby assuring stability of the optical travel path.
Abstract:
A scanner head cartridge is constituted by a lower case which houses optical parts required for reading and electrical parts required for image processing, and an upper case which can engage with the lower case to cover the open surface of the lower case, and a positioning guide means used upon inserting the cartridge into the carriage is formed on the surface of the upper case, that is opposite to the lower case. A scanner head cartridge is held on a carriage that moves an ink head cartridge of an ink-jet printer for performing recording on a recording medium, in place of the ink head cartridge, and can be commonly used using a common base unit even in carriages which mount different ink head cartridges and have different shapes. In addition, the scanner head cartridge allows easy adjustment of the optical system.
Abstract:
At an optoelectronic dust sensor, opening(s) is/are formed at front panel(s) of main body housing(s), and passage hole(s) is/are formed at back panel(s) of main body housing(s). Provided between such back panel passage hole(s) and front panel opening(s) is/are dust passage route(s) permitting passage of dust and/or smoke. Passage hole(s) is/are for introducing dust and/or smoke to dust passage route(s). Opening(s), being for discharging dust and/or smoke from dust passage route(s), is/are sufficiently larger than passage hole(s).
Abstract:
An element holder is a single-piece member integrally having a light-blocking component for limiting the spread angle of light. The element holder includes a cylindrical internal path and can detachably hold an optical element on one end. A lens is affixed on the opposite end of the element holder. The element holder is a molded plastic product, and includes a single light-blocking wall integrally molded with the element holder to extend across the internal path in a level approximately equally spaced from the optical element and the lens to limit the spread angle of light.
Abstract:
To provide a photo-interrupter which can anchor a light-emitting device and a light-receiving device to a concave case in an expensive configuration. The photo-interrupter (1) includes a light-emitting device (6) and a light-receiving device (7) each with a lens projected forward being housed oppositely to each other within an concave case (2) of an opaque resin mold. The sides of the lenses (6a) and (7a) of the light-emitting device (6) and the light-receiving device (7) are secured onto the end faces 5x and 5y of openings (5a) and (5b) formed on the opposite inner surfaces of the case (2). The left and right outer surfaces (2x) and (2y) of the case (2) are bent to form pressing portions (2u) and (2v). The backs of the light-emitting device (6) and the light-receiving device (7) are pressed by the pressing portions so that they are anchored to the case (2).
Abstract:
A motive force detection system prevents an overpowering of the movement of a transport box-carrying slidable tray of a FIMS system past a reference location upon detection of improper mating of the transport box to the FIMS system port plate or an obstruction to the movement of the slidable tray.
