摘要:
The present invention provides a porous ultrafine grinder including ultrafine abrasive grains of diamond or cubic boron nitride having an average grain size of 60 .mu.m or less, and a binder which can form a fused phase by fusion with the ultrafine abrasive grains under heating. The binder is a porous material having continuous pores, and the fused phase formed in the interface of the binder and the ultrafine abrasive grains has a thickness of 1.5 .mu.m or less.

A piezoelectric gas jet generator includes a piezoelectric vibrator and upper and lower volume-varying chambers formed above and below the piezoelectric vibrator. In order to effectively use the movement of air supplied with the vibration of the piezoelectric vibrator, plural upper supply pipes and lower supply pipes communicating with the upper and lower volume-varying chambers and protruding from an upper housing and a lower housing are made to protrude in a direction parallel to the plane of the piezoelectric vibrator so as to be parallel to each other. Here, the upper supply pipes and the lower supply pipes are located at different planar positions.

A diaphragm pump includes a duct structure capable of connecting an inlet port and an outlet port without using a tube. In the diaphragm pump, each of an inlet channel hole and an outlet channel hole is formed as a depression without the provision of inlet and outlet ports each formed as a protrusion on a housing, and a tubular protrusion provided on a plate forming a channel is fit in the depression.

A non-reciprocal circuit device includes a dielectric that is a multilayer board in which a plurality of insulating sheets are laminated; a first central conductor, a second central conductor, and a third central conductor that are disposed in different layers of the dielectric, and are arranged vertically such that they partially cross one another; a flat ferrite member disposed on the undersurface of the dielectric; a first capacitor, a second capacitor, and a third capacitor that are disposed on the undersurface of the dielectric; and a case for accommodating the ferrite member. The dielectric with the central conductors, the ferrite member, and the capacitors are integrated together to form a half-finished product, which is then placed in the case.

摘要:
A nonreciprocal circuit device includes a box-like yoke consisting of upper and lower yokes. The yoke accommodates a magnetic assembly consisting of a magnetic body and first to third line conductors, chip capacitors connected to ends of the line conductors, and a magnet. The first and second line conductors are input and output terminals, and an end of the third line conductor is connected to a terminating chip resistor. The chip resistor is longitudinally disposed such that its long sides are substantially perpendicular to a line between ends of the input and output terminals. The end of the third line conductor is connected to a terminal electrode on the hot side of the terminating chip resistor. A terminal electrode on the earth side of the terminating chip resistor is directly connected to the lower yoke, and a notch is formed in the lower yoke under the hot side terminal electrode.
