PURPOSE:To obtain a compact spectrophotometer, by combining optical fiber and a spectroscope part having approximately the same outer diameter as said optical fiber. CONSTITUTION:Luminous flux from a light source 1 is transmitted to a sample A through an optical fiber 8a for incident light. The light is reflected by the sample A and made incident on an optical fiber 8b for the reflected light. A s...

A surgical equipment for transmitting surgical output power such as laser beam from a hand piece is provided with a pressure sensing element of which resistance changes with the force externally applied to the hand piece so that the pressure sensing element senses an operator holding the hand piece.

An automatic running work vehicle in which both front wheels and rear wheels can be steered and which is provided with a follower sensor for detecting the boundary between an unworked area and a worked area and an orientation sensor for detecting the running direction so as to run automatically along the boundary. Based on the result of detection of the boundary by the follower sensor and on the r...

A release ski binding having a sole plate which in its center area can be pivoted about an approximately vertical axis and can be tilted up about a transverse axis arranged in front of the vertical axis, which sole plate is held on the ski in the skiing position by a resilient holding mechanism, which holding mechanism is responsive to a swivelling movement of the sole plate relative to the ski an...

A PNPN layer type gate turn-off thyristor including a first gate and a second gate comprises, in particular, a second P-type layer such that the impurity atom concentration at the auxiliary thyristor portion is lower than that at the main thyristor portion. Since the first gate disposed at the auxiliary thyristor portion is first fired and then the main thyristor portion is turned on, the above-me...

The present invention relates to a safety binding of a boot on a ski comprising two lateral clamps (4) movably mounted under the action of an elastic member (28) parallel to the plane of the ski (3) between a closed position in which the clamps coact with the sole of the boot and an open position. Each clamp (4) is connected to one end of a longitudinally slidable strip (45) by means of articulate...

Melt extruded poly(6-oxy-2-naphthoate-4-oxybenzoate) shaped articles of relatively high strength and modulus are produced in a lesser period of time than commonly heretofore required in the prior art. The required polymer is capable of exhibiting an anisotropic melt phase and is formed through the reaction of 6-acetoxy-2-naphthoic acid and 4-acetoxybenzoic acid under a combination of melt polymeri...

A novel class of resinous organosiloxane polymers includes triorganosiloxy, fluorinated organosiloxy, SiO4/2 and silicon-bonded hydroxyl groups. The fluorine-containing hydrocarbon radicals are bonded to silicon by means of a sequence of at least two methylene group. Preferred organosiloxane polymers stabilize the cellular structure of polydimethylsiloxane foams during curing.

An optical recording and reproducing apparatus includes a first semiconductor laser for emitting a recording laser beam whose intensity is modulated in accordance with an information signal to be recorded and a second semiconductor laser for emitting a reproducing laser beam having a constant intensity. The recording and reproducing semiconductor lasers are commonly mounted in a supporting member ...

PURPOSE:To enable lead-out electrodes of shape fitted to the pattern to be easily formed even when the metallic electrodes of a semiconductor pellet has a complicated pattern shape, by forming the lead-out electrode out of an Si substrate. CONSTITUTION:Island emitter regions 4 isolated from each other are formed in a base region 3. In such a manner, the region 3 and the regions 4 appear on the sid...

A method of producing a drive shaft with drive elements on a cylindrical basic part includes forming a desired contour for a drive element on pairs of discs, forming holes in the discs of each pair having axes being inclined relative to the surfaces of the discs and having inclinations being opposite to and mirror images of each other, pushing the discs onto a cylindrical basic part with the disc ...

A safety device in the form of a spring applied actuator includes a two-part housing (10, 11), in which a pressurized fluid is applied to a diaphragm 12 to compresses a set of springs (23, 24) within the housing, in order to maintain a friction surface (4) in a retracted condition and apart from a rotating surface (R). A diminution of fluid pressure enables the previously compressed spring set (23...

METHOD AND MEANS FOR TRANSMITTING DATA THROUGH A DRILL STRING IN A BOREHOLE Data are transmitted through a column of drilling fluid in a drill string that is being applied in drilling a borehole in an underground formation. The data are in the form of pressure waves (such as pressure pulses) and are generated by means of a down-hole liquid motor that is driven by the drilling fluid. The pressure w...

A digital device time-multiplexes the execution of multiple tasks that are defined by respective sequences of control words in a control memory. In this device, the time-multiplexing is performed by sending control signals that are representative of respective resume addresses along with each output message sent by the device that calls for a response. These response messages are thereafter receiv...

The arrangement comprises a frame 1 arranged on the lamp, with a circular opening and a fastening plate 9 fixed on said opening. In order that an angle lamp can be rotated into a desired position for final fastening, the frame of known lamps has oblong holes designed for fastening screws. A disadvantage of these holes is that water easily penetrates the lamp via these holes. The possibility of rot...
