A laser distance measuring apparatus, for measuring the distance between objects existing in two directions at least as seen from the apparatus by using laser light, comprises two projectors for projecting laser beams along a specified projection axis toward each one of the objects, a photo detector for receiving reflected light of projection from each object, a distance measurement processor for measuring the distance from a reference point of the apparatus to each object on the basis of the reception signal to the projection by the photo detector, and a distance calculation processor for calculating the distance between the objects on the basis of the distance data measured by the distance measurement processor and the angle formed by two projection axes, in which the projection axis by one projector is variable in angle with respect to the other projector. Therefore, the distance between objects can be measured easily and at high precision by one distance measuring operation only.

This invention relates to a coil unit of coreless armatures. Inner and outer cylindrical coils formed of parallelly arranged coil element wires of an equal length are fitted and combined with each other and overlapping parts thereof are joined sequentially to form electrically closed loops. The thickness in the radial direction of the coil unit is made uniform by means of the foregoing formation. Also, as the length per turn of the coil element wires becomes uniform, a coil unit excellent in the dynamic balance can be obtained and, further, the shape of the cross-section of the coil element wires can be made proper with the cross-sectional area made constant, so that motors of different numbers of turns can be easily designed.

A method of making outer blades for electric shavers wherein a metal sheet in which many hair inlet holes are made by punching or coining process is subjected to grinding process performed on the side at which the blade is to engage inner blade of the shaver and then to pressing process with a soft ram pressed against a rigid body on which the sheet is placed, so that any grinding fins remaining on peripheral edges of the respective holes will be thereby removed.

An energy-beam welding method for two metal pieces is performed by bringing a cylindrical jig into axial engagement with one of the metal pieces at welding zone between them which are placed as joined, and irradiating an energy beam to the welding zone through the cylindrical jig in its axial direction, causing at least part of the energy beam reflected on inner peripheral wall of the cylindrical jig to be directed to the welding zone, whereby the metal pieces are mutually welded easily reliably.

An improved method of manufacturing coreless armatures typically for coreless motors, according to which a coreless cylindrical coil and an insulative disk member carrying commutator segments and rotary shaft are mechanically strongly coupled together without any adhesive agent, is provided. A radially inward compressive force is applied to the outer periphery of the coil within which the disk member is inserted at position for the coupling until coil windings partly bulge inwardly to clamp the peripheral edge of the disk member whereas a substantial part of the windings is compressed dense and into a smooth cylindrical shape.

A method of making cylindrical rotor coil for use in coreless motors is provided whereby the coil is of a reduced thickness with compressed coil turns enabling the stator magnetic gap distance to be reduced, thus enabling a higher flux density to be utilized highly efficiently in the gap. A force is applied to a cylindrically wound coil of an insulation coated wire so as to act in its radial directions and against at least one of the inner and outer peripheries of the cylindrical coil, whereby respective turns of the wire are compressed together and flattened on the plane defining the respective peripheries. The force application is preferably repeated while varying the relative position of the cylindrical coil in its peripheral directions to the applied force.

In an information signal editing device, when a user specifies a desired reproduction section or reproduction start position, a management information file recorded in a memory is rewritten into a second management information file which is created on the basis of the specified information, and a second information file is set on the basis of the second management information file. The information signal editing device constructed as described performs arbitrary virtual editing when a DVD-RAM disk is non-rewritable, whereby the user can obtain a desired reproduction signal.

A rotor of a coreless motor high in mechanical strength and durable against a high torque for a long time is provided. A non-metal disk member is provided for holding a cylindrically wound coil secured at its one axial end to the periphery of the disk in coaxial relation to a metallic rotary shaft coupled at one end to the disk member whereby the coupling force between the disk member and the rotary shaft is made high. The disk member and rotary shaft may be made into an integral body with the same metal material. Commutator segments for feeding a source current to the coil are provided on the disk member through an insulative layer.

Actuation of a prefatiguing lamp is selectively controlled in accordance with the measured time interval between successive copying operations. In substantially continuous copying where the measured interval is less than a first predetermined time period, no prefatiguing illumination is provided. Where the measured interval exceeds a second, longer predetermined time period, full illumination is provided. When the measured interval is between the first and second predetermined periods, partial illumination is provided by appropriate reduction in the operating voltage impressed upon the prefatiguing lamp.
