A photoflash lamp-reflector module particularly suitable for use in a four-sided photoflash array such as a flashcube. The reflector is formed in the shape of a parabola having curved winged portions whose tangents form an angle of more than 45.degree. with respect to the optical axis of the reflector. Due to the curvature of the winged portions, a series of reflectors may be arranged in a back-to-back relationship with each other to form a flashcube assembly without any interference or distorti...

An isolator suitable for miniaturization due to a reduction in the size of a capacitor is provided. The isolator includes a flat plate-shaped ferrite member 4, and first, second, and third central conductors 5, 6, and 7 arranged on different planes in a vertical direction with dielectric bodies sandwiched therebetween so that parts thereof cross each other in the vertical direction. The ferrite member 4 is of a rectangle with long sides 4a and short sides 4b. One of the central conductors is loc...

A membrane comprising a composition including (a) 1 to 99 wt-% of at least one polyurethane elastomer comprising at least one hard segment and at least one soft segment, and (b) 99 to 1 wt-% of a solid, wherein said solid is incorporated in said at least one polyurethane elastomer.

The compositions comprise: (a) from 1 to 99% by weight of a pigment (I) having a primary particle size of from 5 nm to 100 .mu.m which is a solid Ia or a compound Ib which acts as cathode material in electrochemical cells or a compound Ic which acts as anode material in electrochemical cells or a mixture of the solid Ia with the compound Ib or the compound Ic, (b) from 1 to 99% by weight of a polymeric material (II) which comprises: (IIa) from 1 to 100% by weight of a polymer or copolymer (IIa) ...

Pillow (1) suitable for women's body, allowing an easy resting an easy resting to women's chest, keeping breasts separated therebetween and raised, unflattened by the body. The pillow has a donut shape additionally allowing an effective body side support, and it comprises: a substantially oval annular pillow main body (2), having a central opening allowing breast insertion and a resting surface (3) for the chest area surrounding the breast; a pillow secondary body (4) of elongate shape, located ...

A primary radiator includes a waveguide holding a dielectric feeder on which a radiation part, an impedance-conversion part, and a phase-conversion part are integrally formed. The radiator part widens from the aperture of the waveguide, and the phase-conversion part intersects a probe at an angle of substantially 45 degrees. Also, on the impedance-conversion part, a pair of curved surfaces are formed converging in the direction from the radiator part to the phase-conversion part, the impedance-c...

Fastening parts suitable for recycling are disclosed. The fastening parts include a plastic main body with at least two engaging projections, and metal inserts having interior screw threads contained integrally inside the plastic main body. Designing electronic equipment using such fastening parts enable easy parts separation from the plastic main body at disassembly, and facilitate recycling of both fastening parts and the plastic main body.

An oil tank suitable for an aircraft mounted gas turbine engine is divided into three series connected chambers. Aerated oil after engine use is fed into the first chamber and de-aerated oil withdrawn from the third chamber for engine use. The chambers are interconnected in such a manner that when the tank is inverted, a reservoir of oil is retained within the third chamber to provide a continued supply of oil to the oil outlet for a finite time period and insufficient oil flows into the first c...
