Abstract: A terminal switching control apparatus, used for a combination of a voice terminal device and a non-voice terminal device, comprises a call signal recognition detector to detect an incoming signal and distinguish the detected signal between an voice signal and an non-voice terminal call signal, a device for transmitting a response message to urge the calling party to respond if no incoming voice signal is detected, an action request device for urging the called party to respond by the voice terminal device when an incoming voice signal is recognized after transmitting the response message, a control device for switching the line connection to the non-voice terminal device if neither the voice signal nor the non-voice signal is detected by the call recognition device, and a set of mode selector switches for selecting a presence mode and an absence mode according to the presence/absence status of the called party.

Abstract: A circular electromagnetic flow coupler comprises a circular flow path, conductive partition walls which divide the circular flow path into generator side flow paths and pump side flow paths in the circumferential direction thereof, insulators for insulating the inside and outside of the flow paths, and magnetic poles for generating a magnetic field in the radial direction of the circular flow path. The insulators are provided with openings so that they are not damaged when pressure is exerted thereto.

Abstract: An apparatus for assembling a tubular mesh ring annularly interposed between a tubular casing in a catalytic converter and a columnar catalyst unit inserted therein, the mesh ring alternately having a plurality of crests and roots extending incliningly with respect to an axis of the catalyst unit when mounted to the converter, the assembling apparatus comprising a pair of side receiving members for supporting the sides of the mesh plate with an overlapped portion of the mesh tube positioned on top and the axis thereof oriented to be substantially horizontal, a lower receiving member for supporting the lower portion thereof, an upper receiving member for supporting the overlapped portion from below, an electrode secured to the upper surface of the upper receiving member and capable of bearing against the overlapped portion from below, a pressing plate for urging the overlapped portion against the electrode, and an electrode tip in cooperation with the electrode to spot-weld the overlapped portion of the mesh t

Abstract: An inspection device for detecting faulty prints on a printed matter running at a high speed. The prints on the printed matter are held as if they were stopped on account of the employment of an even-numbered polygonal prism which rotates in synchronism with the running speed of the printed matter and which allows an inspector's eye to catch successively the prints on an optical axis not only at their positions on said optical axis but also at their moving positions before and behind said optical axis.

Abstract: A cassette, cartridge, box or magazine for storing and projecting transparencies or slides as well as a viewer or projector, the cassette and the viewer or projector matching each other. Said cassette having two compartments for stacks of slides and a structure connecting said compartments and being provided with a passage for moving the slides one by one from the bottom of one compartment to the other compartment and preferably from the top of the last named compartment to the first named compartment through a second passage. The connecting structure being adapted for attachment to a projector or viewer with a slide in said passage being arranged between a light source and a focussing lens. The viewer or projector being provided with means for pushing the slides one by one from one compartment through the passage into the other compartment.
