A magnetic bubble decoder employs forward magnetic bubble paths each forming a magnetic bubble shift loop, backward magnetic bubble paths, series switches disposed in the forward bubble paths, for straight advancing the magnetic bubbles and parallel switches, disposed in said forward bubble paths, for branching the magnetic bubbles from said forward paths to the backward paths. Control lines are provided for alternatively energizing the series and parallel switches to be operated in cooperation ...

A sealed type current interrupting device for vehicles comprising electrode members for making and breaking current, a catalyst column containing a catalyst for decomposing ozone generated between said electrode members, and a casing member for sealing said electrode members and said catalyst column, whereby said electrode members and said catalyst column are substantially isolated from the outer atmosphere.

A device, in which light waves are directed to the surface of a periodic structure constituted of a material having high reflectivity of the light wave used, whereby a field having a periodic strength of an electric field vector of the light wave is generated in the vicinity of the surface of said periodic structure, and the energy of the light wave is supplied to the charged particles while said charged particles pass through said field, thereby accelerating the charged particles.

Movable magnetic compensating pieces are disposed on a lower magnetic path unit of an electron lens. The compensating pieces are in partial contact with the lower magnetic path unit and moved toward and away from each other on the lower magnetic path unit by manipulation form the exterior of the lens.

A field effect semiconductor device including a plurality of field effect semiconductor elements formed on a common substrate and a compensating circuit for controlling the threshold voltage of said transistors by comparing the threshold voltage of one transistor to a reference voltage and generating a backward bias control voltage across a PN-junction of the one transistor between the source thereof, which is connected to the source of at least one of the other transistors, and the common subst...

A semiconductor substrate of Group III-V compound such as GaAs or GaP covered uniformly with powder of the same kind of semiconductor with grain diameters of 20-500.mu. is placed in a quartz tube and a small piece of zinc is also placed in the tube at a place separated from the substrate, the zinc is heated above 700.degree. C to evaporate it by a heating coil placed around the zinc, the substrate is also heated by a coil around it independently of the zinc, and a zinc gas is flowed by being car...

A light source lamp for atomic light-absorption analysis comprising a structure constituted by a molded body of fine metal wires having a relatively high-melting-point which are mechanically closely linked with each other having a metal having a relatively low-melting-point impregnated in the gaps between the fine wires, wherein the metal of a low-melting-point is continuously fed to a hollow portion through the gaps between the fine wires while maintaining the contour of the structure by virtue...

Disclosed is a method of implanting impurity ions wherein such ions are implanted into the surface of a semiconductor partially exposed by a hole in two layers, one being made of silicon oxide and the other being made of a metal such as aluminum.

The length of the entrance edge of each blade on the side of the crown ring is made longer than that on the side of the shroud ring; and the runner satisfies the following three conditions: 15.degree..ltoreq..theta..ltoreq.35.degree. .gamma..sub.1 c.ltoreq..gamma..sub.1 s D.sub.1 c.ltoreq. D.sub.1 s Where .theta. = an angle between the centerline of the runner and a line connecting the points at which the entrance edge of the blade contacts with the crown and shroud rings respectively; .gamma..s...

A counting device for measuring the repetition rate of a pulse signal which uses a monostable multivibrator including a constant-voltage diode connected in parallel with one of two switching elements which are connected in a monostable multivibrator configuration, thereby producing a measuring output signal which is independent of any voltage change in the operating power source for the monostable multivibrator.
