In an endoscope for displaying an image of an object on a monitor screen, a static induction transistor (SIT) image sensor having a number of light receiving elements is arranged at a light emitting side of an image guide bundle. In order to eliminate dead spots appearing in the displayed image due to broken fibers in the image guide bundle, pixel signals of light receiving elements corresponding ...

A loudspeaker is disclosed having an enhanced response at bass frequencies. The loudspeaker includes a tubular enclosure having a pair of outwardly directed, opposing loudspeaker drivers mounted over each end. A port is provided through the enclosure midway between the drivers and is coupled to the exterior of the loudspeaker by a perpendicularly projecting duct. The length and cross-sectional are...

Semiconductor wafers having patterns of steps and grooves defining microcircuit elements thereon are coated with metallic film by supporting the wafers individually adjacent a respective ring-shaped sputtering source in stationary relationship thereto. Within a short deposition time of approximately one minute, good uniformity of deposition across the main wafer plane is obtained by maintaining so...

Welding apparatus is disclosed for collecting and disposing of the extraneous work piece particles thrown off during the machining and, in particular, the welding of the workups. The welding apparatus comprises a welding chamber for receiving the work piece and for establishing a welding environment about the work piece. The welding chamber has an opening and an input port for introducing a non-re...

An absorbent product has a central absorbent element. Flaps (22, 24) extend from each of the longitudinal edges of the product. Pressure sensitive adhesive (30; 32) is centrally located on the garment facing side of the pro- duct and on the garment facing side of the flaps. A single release strip (28) has a first side covering the centrally locate adhesive (30). The flaps (22, 24) are folded over ...

A single layer copper foil tape is provided having a center core and connected lead beams. Etched apertures are formed to separate adjacent lead beams and to form relatively high strength foil straps connecting edge portions of the foil tape and the center core. Score lines may be etched at the ends of each of the lead beams to form breakaway links at such ends. The inner ends of the lead beams ar...

A temperature-controlled tank container comprises a heat-insulating jacket (23) surrounding the tank on all sides with a uniform close spacing. The space between the tank and the jacket (23) is subdivided into compartments by reinforcing rings (13), end rings (14), and partition webs (30) which extend on either side of the vertex line. By means of through-holes (37...42) formed in the reinforcing ...

A pressure sensor (100) includes a pressure sensitive element and associated integrated circuitry on a common silicon chip (29). Fusible links in a conditioning network of the integrated circuit are opened by electrical pulses applied to pinouts (31) that are accessible for probing in a trough (24) in the support housing (10) that is exposed during the testing and adjusting phase, but is sealed of...

In an insertion section of an endoscope according to the present invention, a plurality of flexible segment tubes, each having a predetermined length and a predetermined inside diameter, constitute necessary ducts for the endoscope, individually. The ducts include an image guide duct, light guide duct, instrument channel duct, and air/water channel duct. The flexible segment tubes are fixed in a h...

A stopper device for use on a pharmaceutical closure, comprising an elastomeric stopper sized to function as a closure; and a polyurethane coating on the stopper. The coating has a modulus sufficient to decrease the coefficient of friction of the stopper to less than 0.6.

Multi-party conferencing apparatus for use in a pulse code modulated, time division multiplexed telephone communication system including a data bus on which operating times are divided into equal frames of time and each channel of a plurality of channels has a transmit time slot and a receive time slot in each time frame. Voice signals on conferencing channels are sampled in each time frame and co...

A method for generating additive combinations of PCM voice samples separates the samples into magnitude portions and sign portions. The magnitude portion of each PCM voice sample is converted from compressed PCM form to linear form. The magnitudes of the two voice samples, in linear form, along with their respective signs are added together to form a resultant linear value. If there is any overflo...

PURPOSE:To enable detection of residual capacity simply without considering a battery temperature, by determining correlationship between the residual capacity and a differential internal resistance from a lead-acid battery with a known residual capacity to detect a residual capacity based on the correlationship. CONSTITUTION:In a lead-acid battery with a known residual capacity, relationship is d...

A rear cushion unit having an oil storage chamber integrally arranged therewith at the upper rearward side thereof on a motorcycle. An air cleaner is arranged behind the chamber with an intake passage at the upper portion thereof. Spacing is provided around the chamber and the air intake passage such that air flow may be drawn around the chamber by the intake passage when the engine is running. In...
