Abstract: A key signal is supplied through an I/O port to a chord discriminating section of one electronic musical instrument, which generates corresponding accompaniment tone data. The accompaniment tone data is transferred through the I/O port to a tone signal generator of a different electronic musical instrument without auto-play accompaniment function, whereby accompaniment tone is generated from the different electronic musical instrument.

Abstract: Disclosed is a foot switch apparatus which is connected to a tape recorder, the tape recorder having a mode control circuit which designates its operation mode. The foot switch has an automatic back spacing circuit coupled to the mode control circuit. When the foot switch operates, a recording tape on the tape recorder is rewound by a predetermined length in response to an operation of the automatic back spacing circuit.

Abstract: A tape recorder has a base plate, a capstan rotatably supported by the base plate and a flywheel attached to the capstan. The capstan is rotated by a drive device having a motor and a driving gear mounted on the flywheel coaxial with the capstan. A pair of magnetic heads are movably arranged on the base plate. A moving gear is rotatably supported on the base. A cam member and a push member are mounted on the moving gear. The push member engages with one of the magnetic head to move the head as the moving gear is rotated. A pair of transmission gears are arranged on both sides of the moving gear to be able to engage with the driving gear and moving gear. The transmission gears transmit the driving force of the drive device to the moving gear to rotate the moving gear by engaging with the driving gear and moving gear. The engagement of the transmission gears with the driving gear and moving gear and the rotating angle of the moving gear are controlled by a controlling device.

Abstract: Data for a plurality of musical pieces is preset in a ROM pack and also on a tape recorder. Musical piece data read out from the ROM pack or tape recorder is supplied from a control section to melody generators, a chord generator, a bass generator and a rhythm generator. Melody data, chord data, and rhythm data obtained from these generators are coupled through an amplifier to a loudspeaker.

Abstract: In an apparatus for manufacturing a spring unit, a pair of movable bodies are slidably mounted on a guide rail which is extended on a frame structure. A pair of rollers are provided on the respective movable bodies and a grip mechanism is arranged on the frame. The ends of a single wire are held between the pairs of rollers and the intermediate portion of the wire is gripped by a grip mechanism so that the single wire is stretched between the movable bodies. A swing arm is axially and swingably supported on each of the movable bodies and a forming roller is pivotably fixed to the respective swing arms. A guide is arranged between the forming rollers and the rollers and a pitch rod is arranged between the guide and the forming roller.

Abstract: A door locking mechanism which comprises a key body to be secured to the hem of a door, a slide key slidably mounted in the key body, the head of the slide key being protrudable out of the key body toward a door frame upon rotation of a locking knob so as to be shifted to its half-locked and complete-locked positions, a key latch to be secured to the door frame, and a half-locking arm anchored to the key latch and provided with an opening to receive the head of the slide key,wherein a pair of inlets are formed on the slide key and one of a pair of pins provided on the locking knob selectively engage one of the pair of inlets on the slide key to force the slide key to slide toward the door frame upon rotation of the locking knob, and a slide plate is vertically slidably mounted inside the key body and biased to hold the pins of the locking knob in a position where the pins disengage with the one of the inlets on the slide key, the slide plate being provided with means for positioning the slide key to its unloc

Abstract: A vibration insulating handle for a pneumatic power tool comprising an inner tube (15) and an outer tube (16) both rigidly but adjustably attached to the tool housing (10). The inner tube (15) forms an air exhaust passage (13) which communicates with a silencer (12) carried on the extreme end of the outer tube (16). The tubes (15, 16) are radially spaced relative to each other leaving an annular heat insulating gap therebetween. A weakened portion (30) on the outer tube (16) is located adjacent the tool housing end of the latter and comprises two axially spaced pairs of peripherally extending slots (27, 28). The weakened portion (30) enables the outer tube (16) to yield elastically in radial directions to bending and shearing vibration forces transmitted to the handle during operation of the tool.

Abstract: A catheter introducer includes a hollow sheath extending continuously from a base end portion thereof to a distal end portion thereof, and a hollow hub having a connection portion for connecting the hub to the sheath in such a manner that the hub and sheath partially overlap. A reinforcing coil body is fitted in the connection portion and extends axially of the sheath from the connection portion toward the distal end of the sheath to a point beyond the connection portion. The hub has a valve for enabling a catheter to be passed therethrough under liquid-tight conditions.

Abstract: Wiping cloth for a cleaning device with squeezing and/or wringing facilities (3), whereby on the T-formation hem reinforcement (8) - central reinforcement (9) fixing studs (10) are provided, which are clipped on with an asymmetrical spacing and with their longitudinal axes (2) being disposed on the central pitch line (21) of the retraction device (5).

Abstract: In a handy reader/printer apparatus for reading recorded information from a desired portion of a medium to be read and printing read information on a desired portion of a medium to be printed, the apparatus has a housing having an opening in a lower surface thereof and placed on the medium to be read or printed such that the desired portion of the medium can be fitted in the opening, a reader unit, arranged in the housing, for reading the recorded information of the desired portion of the medium to be read fitted in the opening while the housing is placed on the medium, a printer unit, arranged in the housing, for printing data in the desired portion of the medium to be printed fitted in the opening while the housing is placed on the medium, a memory for storing data read by the reader unit upon operation of the reader unit, and a readout unit for reading out the storage data from the memory as the printing data to the printer unit upon operation of the printer unit.

Abstract: A tongue therapy device is disclosed for training the tongue to assume its proper posture on the palate and to prevent tongue thrust during swallowing. The device includes an element, such as a pin, for irritating the tongue upon contact. A protective element is provided which keeps the tongue off the irritating element unless the tongue moves beyond a given point. The protective element can be a resiliently yieldable cover for the pin. Alternatively, it can be a ramp sloped to resist forward movement of the tongue. Each device is compact enough to fit on the lingual side of a single tooth. It can be, therefore, mass-produced to fit substantially all individuals and can be installed relatively quickly and easily.
