Abstract: Apparatus for attenuating noise necessarily emitted from output slots of a printer mechanism enclosure and utilizing a minimal amount of enclosure components of significantly reduced size. Input and output housings or compartments for noise attenuation are provided, each of which form elongated narrow guideways. One end of each of the guideways of each of said compartments is aligned with the paper input and output slots, respectively, of the printer mechanism housing and is sealed to prevent noise at the juncture. The guideways have narrow passageways extending therethrough, but are sufficiently wide to permit the paper passing therethrough to move without experiencing any drag resistance due to the presence of the guideways. At least one surface of the guideways confronting and substantially parallel to the moving paper web is lined with a suitable noise attenuating foam.

The circuit arrangement provides a stabilized oscillation and eliminates the likelihood of producing an electric shock.

Abstract: A laser knife comprises a tubular member adapted to be passed through a forceps channel of an endoscope for insertion into a coeloma, holders disposed at the distal end of the tubular member for holding an affected part within the coeloma which is to be cauterized, a laser radiation transmission member for irradiating the affected part held by the holders with radiation from a laser, and a pad on the holders for accepting the laser radiation subsequent to the completion of the cautery, thus preventing the irradiation of normal tissues with the laser radiation.

Abstract: A fixture for an electronic flash includes a connection terminal which enables a synchronized flashlight illumination and another connection terminal which is used to transmit an electrical signal to a camera which is indicative of the completion of a charging operation or a flashlight illumination of an electronic flash. The fixture is constructed to retract said another connection terminal from its abutting surface on a usual hot shoe or an accessory shoe of a camera whenever the electronic flash is mounted thereon, thereby preventing an electrical short-circuiting of said another terminal by the surface.

Abstract: A suspension strap fastener for camera including a rear lid which is pivotally mounted on a camera body by means of a hinge comprising a core shank and a pair of hinge plates, is mounted on a portion of the shank which is not engaged by the hinge plates. The fastener is also formed with a connection with a suspension strap.

Abstract: Apparatus for producing signals of varying volume and pitch which are functions of the magnitude and distribution respectively, of weight (or weights) placed upon a platform hinged at one corner and swingable in mutually orthogonal directions. Sensors convert the physical displacements occurring at first and second corners opposite of the platform adjacent to the hinged corner into signals for controlling the volume and pitch of an output signal. Alternatively, displacement of the platform may be controlled by the application of varying pressure by means other than full body weight, such as the operator's finger(s).The apparatus may be utilized as a unique means for producing music or musical sounds responsive to a person dancing or otherwise moving upon the platform to provide an entertainment form which is both unusual and enjoyable.

Abstract: A protective cover for taking lens of camera comprises a thin sheet which is bent to cover the front, the top and a top portion of the rear of a camera body and is mounted on the camera body so as to be slidable lengthwise thereof between a first position which it covers a taking lens and a second position in which it exposes the lens.

Abstract: A laser knife includes a tubular member adapted to be inserted into the coeloma by being inserted into the forceps channel of an endoscope, a pair of oppositely located laser radiation emitter and acceptor members on the distal end of the tubular member, a laser radiation receiving element disposed on the acceptor for accepting laser radiation which is used for purpose of cautery subsequent to the completion thereof and performing a photoelectric conversion of such radiation, a laser radiation transmission member for transmitting laser radiation to the emitter, and a laser radiation isolator interposed between the transmission member and a laser oscillator and responsive to a laser radiation accept signal from the element for interrupting the supply of laser radiation into the transmission member. In this manner, unwanted irradiation of normal tissues with the laser radiation is automatically terminated after a desired affected part has been cauterized.

Abstract: A replacement ribbon package for ribbon cartridge assemblies. The package comprises a Mobius Loop ribbon arranged in full fanfold fashion within a channel-shaped ribbon holder. A semirigid stripper sheet positioned between the ribbon and the base of the channel-shaped member permits the ribbon to be simply and readily stripped from the channel-shaped member once the package is inserted into the ribbon cartridge housing. A tearaway wrapper, which encircles the channel-shaped member and the ribbon serves to loosely hold the ribbon fanfold portion to prevent any creasing. The package is designed to be placed into the ribbon cartridge housing to simplify the installation operation and eliminate handling of the ribbon portion inserted into the ribbon cartridge housing.The package may be boxed or inserted within a plastic tray having a lid heat sealed to the tray flange.Instructions may be printed upon the enclosure package, the tear strip, or upon a separate insertion.

Abstract: A release electromagnet assembly having a permanent magnet associated with a movable member and which also includes an electromagnet cooperating with the magnet to produce a magnetic attraction therebetween which is effective to constrain the movable member and which is effective to produce a force of repulsion opposing the attraction of the permanent magnet, thereby releasing the movable member for free movement. The permanent magnet has an end pole of a single polarity where it abuts against the electromagnet so that the flux from the magnet partly passes through an external magnetic path external to the yoke of the electromagnet. When energized, the electromagnet produces a flux passing through a magnetic path which is provided internally of the yoke and which opposes the flux from the permanent magnet, thus releasing the movable member from its constraint applied by the permanent magnet.

Abstract: An electrically driven optical instrument such as stereo-microscope is provided with a transfer shaft rotatably carrying a drive transmitting, transfer gear. An axial displacement of the transfer gear occurs in response to an external operation to move the transfer gear selectively to a first position in which it meshes with an output gear on a motor and a second position in which it meshes with a manually driven gear that is mounted on an externally exposed operating shaft, thus accomplishing a switching between an electrical drive and a manual drive.
