A magnetoresistance effect type head or an MR head which includes a main portion further having a casing with a recess at its one surface, for providing a bonding surface in the casing so as to be generally U-shape in its cross section, and a magnetoresistance effect type head chip, a support member for a magnetic tape sliding surface and a terminal member for external connection which are all collectively bonded to the bonding surface, and a cover plate further bonded onto the main portion.

A realistic audio-visual effects generator for simulating anti-tank and a-aircraft missile launching. A pyrotechnic cartridge having disc at one end that ruptures and allows the efflux of the products of combustion to exit through a hole in the breech block which is placed at the muzzle end of the firing chamber. Along with the simulated cartridge discharge is electrical circuitry for determining if the cartridge has been properly chambered. The circuitry acts to prohibit firing should it be det...

An unlined Munroe Effect device for breaching structures in urban terrain. he device is constructed as an unlined, linear, shaped explosive charge which directs an explosive jet into the structure. The shaped charge is formed with a honeycombed substrate of metal in which the substrate interstices are filled with and the substrate is covered by an explosive material. The substrate is embedded in the explosive material. The explosive material and substrate, prior to curing of the explosive materi...

A field effect transistor with small gate leakage current; the gate leakage current being substantially reduced by a low-temperature glass layer formed on a portion of the surface. It is well known that an inversion layer occurs in a P-type region under an oxide layer, such as silicon dioxide, by ions contained in the oxide layer and/or electric fields applied between the P-type region and a conductive layer formed thereon. In a field effect transistor, the inversion layer increases the leakage ...

A multiple effect evaporator apparatus features a plurality of vertically arranged evaporator chambers, each having a plurality of vertically oriented heat exchange tubes molded at their lower ends to a bottom plate of the chamber and supporting a vessel at their upper ends, said vessel being adapted to receive a solution from an upper chamber, an overflow tube of substantially U-shaped configuration connected at one end to an upper part of the vessel and at the other end being open to the press...

A Gunn effect triode is modified to provide a phase modulator. It may, for example, generate a phase modulated output and may be used in a microwave modulator. It consists basically of a main branch and two side branches, each being biased below the threshold electric field. Domain nucleation is initiated by a trigger or input pulse applied to the main branch and the pulse may be diverted by triggered gates into a selected one of the two side branches. The effective length of each side branch is...

In a water purification plant, where a coagulant is dosed into raw water to coagulate turbidity-causing particles suspended in the raw water to form floc, and the water containing the floc is led to a sedimentation basin to separate the floc by sedimentation, thereby purifying the raw water, a coagulation effect is quickly detected by by-passing a portion of the water containing the floc and flowing to the sedimentation basin through a filter column of an apparatus for detecting a coagulation ef...

A color photographic material is provided in which the interimage effect is adjusted to provide optimum color reproduction. The photographic material comprises an emulsion referred to as type I emulsion, which releases an inhibitor on development and another emulsion with underripened grains which are more soluble than those of the type I emulsion.

A vertical or horizontal type junction FET including a channel-gate structure formed by a double diffusion process in which two treatments for diffusing different impurities are executed through an identical opening provided in a diffusion mask. For fabricating a vertical type junction FET, such double diffusion process is applied to stacked upper and lower semi-conductor layers having opposite conducting types thereby forming a channel region adjacent to the upper semi-conductor layer which fun...

A ground-effect vehicle having a base frame and a downwardly extending skirt, rides on an air cushion created by injecting air downwardly through the frame into the space beneath the vehicle. In order to prevent the down draft of the air injected under the vehicle from damaging fragile objects, such as young plants, a deflector is provided to divert the air flow parallel to the ground and to reduce its velocity, while still maintaining sufficient pressure in the air cushion to permit the vehicle...
