A push-button switch including a housing which is integrally molded with a first metal plate and a second metal plate. The first metal plate includes a fixed contact, and the second metal plate includes a main portion, a bridge section extending from the main portion, and a bowl-shaped movable contact on a forward end of the bridge section. The housing is provided with a recess for exposing the fixed contact on the inner bottom face thereof, a plurality of caulking walls formed in an annular for...

An apparatus and method for forming dough and dough pieces to a thickness of as little as 1 mm. The apparatus generally comprises a plurality of powered externally rotated rollers spaced above a plurality of moving conveyor belts. The dough is pressed and stretched without breaking by the action of said rollers and said conveyor belts.

A transfer device for transferring articles in one or more lines to a subsequent station simultaneously comprising a first belt conveyor suspended from a fulcrum shaft and a second belt conveyor positioned underneath said first belt conveyor at right angles thereto, the first belt conveyor being swung periodically so as to transfer articles thereon to said second conveyor.

An electromagnetic driven variable electrical resistance device has a variable resistor mounted onto the front side of a case and provided with a rotatable shaft to which a drive-gear is attached. A pair of solenoids are mounted onto the bottom panel portion of the case. A pair of movable driving-pawl members are pivotally supported by the recess portions of an E-shaped spacer attached to the case and are biased by a pair of spring means and held in an upper limit position by a T-shaped stopper ...

A snap-action operable push-button switch has a metal contact of rectangular shape having a pair of rectangular holes at both sides of a central stripe integrally formed therewith, the central stripe being bent toward one side thereof and the metal contact also having a pair of rectangular resilient contact pieces integrally extended therefrom in a size smaller than the size of the rectangular holes.

A variable tuning resistor has a threaded shaft which moves a slider along a linear resistance element. A flexible ribbon is connected at one end to the slider to be moved thereby. A guide member through which the ribbon is guidingly slidable is oriented perpendicular to the shaft extending upwards. The guide member is formed with a window through which the ribbon is visible. The ribbon is formed with a marking such as a slot obliquely along the length thereof in such a manner that as the ribbon...

Two integrally formed fixed contacts each have a lead portion with terminals at the opposite ends extending external of the switch housing and a contact portion connected to the lead portion by a connecting portion. A holder slidable in the housing retains a U-shaped movable contact which is movable to and from a position in which the opposed internal faces of the movable contact engage with the opposed external faces of the fixed contacts respectively to establish ohmic connection between the l...

Apparatus for transferring formed articles such as confectionery, bread or the like from a feed conveyor through a displaceable transfer conveyor onto a receiving conveyor, trays or boxes without tumbling, deforming or injuring the formed articles, the transfer conveyor being moved substantially downwardly at a velocity greater than the falling speed by gravity of the articles thereon, and then swung substantially laterally at a velocity sufficient to avoid contacts with the falling articles, an...

In a VHF-UHF tuner, the signal from the VHF antenna is fed to a resonant circuit comprising a plurality of coils which are selectably shorted out by a channel selection switch to select the various channels. The output of the resonant circuit and the UHF IF signal are fed to a band switch integral with the channel selection switch. The channel selection switch is adapted to short out the coils of the resonant circuit when in the UHF position to attenuate the VHF channel 2 signal component and pr...

A VHF mixer serves as an amplifier-mixer for VHF and an IF amplifier for UHF and CATV. UHF and CATV tuners produce the UHF and CATV IF signals respectively. A band selector switch enables a VHF local oscillator and disables UHF and CATV local oscillators to receive VHF, enables the UHF local oscillator and disables the VHF and CATV local oscillators to receive UHF and enables the CATV local oscillator and disables the VHF and UHF local oscillators to receive CATV.
