A semiconductor excitation solid-state laser apparatus, in which a cross-sectional area of an optical guide plate leading an excited beam emitted from a semiconductor laser element to a solid-state laser medium is made larger in the side of the semiconductor laser element thereof, while a cross-sectional area thereof is made smaller in the side of the solid-state laser medium.

A data transmission system, a receiver, and a recording medium in which a re-coder (16) generates pseudo transmission signals based on the virtual received data after a decoder (15) generates virtual received data based on virtual decision data from a virtual decision circuit (12), and a soft-decision circuit (18) outputs soft-decision data so as to decrease the number of different bits between th...

A skate provided with a supporting frame for in-line wheels and comprising a shoe which is composed of a nonrigid upper that, in a sandwich-like fashion, surrounds a stiffening element which affects the regions of the tip, of the heel, of the ankle and of the sole of the foot, and a lateral band or rim made of rubber which externally and laterally surrounds said upper proximate to said region of t...

A door obstruction detector employs an optical device, such as a segmented Fresnel lens, and a PIR sensor attached to a moving door, so that the optical device causes an image of an object, in a detection zone, to move across a sensing region of the PIR sensor when the door moves. When the object is sensed in the detection zone, a drive signal is generated for controlling movement of the door. The...

A peel seal zipper tape for reclosable plastic bags or packages includes a first and a second mutually interlocking zipper profile disposed on a top surface of a laminated film strip. The top surface is formed by a layer of a sealant material. The laminated film strip also has a middle layer, or core, of a material stiffer than the first and second mutually interlocking zipper profiles, and may al...

An optical multiplexing device is provided comprising multiple wavelength division multiplexers cascaded together. A first one of the wavelength division multiplexers has a common port and multiple optical ports which are optically co upled to the common port. The common port may be optically coupled to a trunk line of a system employing wavelength division multiplexing, for example, a fiber-optic...

For transmitting information about the neighbouring cells to mobile stations, a base station of a cellular radio system creates a message (27, 27') containing information about the neighbouring cells and transmits it to the mobile station. In addition to the transmission frequencies used in the neighbouring cells, the base station includes in the message other information characterizing the neighb...

The heat exchanger surfaces coming into contact with the hot gas comprise an iron-chromium-aluminium alloy. DETAILED DESCRIPTION - A heat exchanger for recovering heat from oxidising combustion gases containing lead oxide has its surfaces exposed to the gas made from an alloy comprising 2-10 wt.% aluminium, 10-40 wt.% chromium and the balance iron.

A laser shines light onto an object which is reflected back through a lens onto a light-sensitive measuring cell linked to a signal generating circuit, which only sends a signal when an object is detected within a given variable detection region. Light from a laser (26) is reflected by an object (40) through a lens (20), which directs it towards a light-sensitive measuring cell (24). The optical ...
