摘要:
A key telephone system for a predetermined number of outside lines comprises only one control lead shared per outside line by cables connected between a key service unit and key telephone sets, respectively. Each telephone set has manually operable keys for supplying a higher voltage to a relevant control lead while an outside line is selected for an answer or a reanswer to a call present thereon and substituting a lower voltage for the higher voltage when it is desired to hold an answered call. Associated with each outside line and with the control lead therefor, the service unit comprises a unit comprising, in turn, a signal producing circuit for producing a first and a second intermittent signal while a call present on the associated line is not yet held and placed on hold, respectively, a supply circuit supplied with each intermittent signal for supplying a corresponding one of a flashing and a winking signal to the associated lead, a detector for detecting noncorrespondence of a signal supplied to the supply circuit and a signal supplied to the associated lead to produce a control signal, and a hold circuit responsive to the lower voltage supplied to the associated lead for holding the call. The control signal stops production of the first intermittent signal and takes the call off hold when produced while the call is not yet held and placed on hold, respectively. Outside line status indicating lamps are connected in each telephone set to the respective control leads.

The present invention aims to ensure strength of a thin-walled sintered magnet. A sintered magnet is a ferrite sintered magnet made by sintering a magnetic material. A magnetic powder mixture obtained by mixing magnetic powder with a binder resin is injection-molded into a mold with a magnetic field applied thereto to produce a molded body, which is then sintered to produce the sintered magnet. The sintered magnet has a thickness of 3.5 mm or less in the position of center of gravity thereof. The sintered magnet has a surface roughness Rz of 0.1 or more and 2.5 μm or less. The surface roughness Rz is a 10 point average roughness.

摘要:
An information readout method for an optical information medium comprising an information recording layer having pits or recorded marks representative of information data involves the step of irradiating a laser beam to the information recording layer through an objective lens for providing readings of the pits or recorded marks. When the laser beam has a wavelength λ of 400 to 410 nm, the objective lens has a numerical aperture NA of 0.70 to 0.85, and the pits or recorded marks have a minimum size PL of up to 0.36λ/NA, readout is carried out at a power Pr of at least 0.4 mW for the laser beam. When the laser beam has a wavelength λ of 630 to 670 nm, the objective lens has a numerical aperture NA of 0.60 to 0.65, and the pits or recorded marks have a minimum size PL of up to 0.36λ/NA, readout is carried out at a power Pr of at least 1.0 mW for the laser beam. Pits or recorded marks of a size approximate to the resolution limit determined by diffraction can be read out at a high C/N.
摘要:
The apparatus forms an electric circuit on a construction member of a machine based on a set of three-dimensional data. The data defines a position and a profile of the construction member, a position of the electric circuit, and a shape of the electric circuit. The electric circuit is used for electrical connection between electric instruments mounted on the machine. The data is associated with a reference coordinate system provided in the machine, and the data includes coordinates of points for determining arrangement of the electric circuit, a distance between any two of the points adjacent to each other, and a cross-sectional area of the electric circuit associated extended between the two points. The apparatus has a storage means for storing the data, a jet means for jetting a molten metal, a first transfer means for moving the construction member relative to the jet means, and a control means for jetting the molten metal against the construction member to deposit the molten metal and for controlling the relative movement between the construction member and the jet means based on the data. The jet means can jet the molten metal against the construction member so that the molten metal can be deposited on a surface of the construction member to form the electric circuit on the construction member.

A rewritable phase-change optical recording medium is provided, which includes a substrate, a first information layer, a spacer layer, a second information layer, and a cover layer. The second information layer includes a recording film containing Sb as a main component and V or V and In as second components. When an amorphous mark formed in the recording film is irradiated with a reproduction beam, crystallization of the amorphous mark occurs only in a central portion in the width direction of the amorphous mark. The width direction is orthogonal to the scanning direction of the laser beam. The recording film is formed of a material that exhibits a change in degree of modulation of 5% or less when recorded information is repeatedly reproduced. The change in degree of modulation is a change from when the number of times of reproduction is 100,000 to when it is 400,000.
