摘要： A capacitance detection type record stylus comprises a conductive shank and a diamond partially embedded in the shank so that the diamond projects downwardly from one end of the shank. The shank is formed with a bottom face for making slidable contact with the disk record. The shank and diamond are formed with a pair of common rear faces inclined with respect to the axis of the stylus to define an electrode forming face therebetween which extends from the bottom face of the diamond partially into the shank. The electrode forming face is inclined at an acute angle with respect to the axis so that the lower end of the electrode forming face is located at a point forward with respect to the upper end thereof and subtends at the lower end thereof at such an angle that the diamond can be lapped without causing defects to occur on the lapped surfaces. The electrode forming face is entirely covered by a conductive layer so that the latter establishes electrical connection with the shank to allow signals detected by the electrode to pass through the shank to an external circuit.

摘要： For detection of signals recorded in the form of minute pits along tracks as capacitance variations, a record stylus is disclosed as comprising a shank having a portion of cross-sectional area decreasing toward one end of the stylus. A diamond, partially embedded in the shank, has a decreasing cross-sectional area toward said end of the stylus as a continuation of the decreasing cross-section of the shank. The bottom and rear face of the diamond are inclined so that the adjacent angle therebetween is smaller than 90 degrees. An electrode attached to the rear face of the diamond extends from the bottom of the diamond toward the other end of the stylus. The electrode is thus inclined in a direction opposite to the direction of movement of the recording medium to provide less concentration of electric lines of force on the rear bottom edge thereof.

摘要： A stylus for detecting signals as electrostatic capacitance variations of the information recorded in the form of geometric variations on a disc record comprises a diamond body and a stylus electrode attached to one surface of the body which makes contact with the disc record. The electrode extends downward to the plane of the contact face of the diamond body to detect the recorded information. The crystallographic orientations of the diamond body are such that the contact face is inclined at a predetermined angle to a crystallographic plane having the tendency to wear substantially at the same rate as the wearing rate of the electrode at its downward tip so that the electrode keeps contact with the record surface for a long period of use.

摘要： A circuit arrangement comprises a first delay circuit which is responsive to the leading edge of a command signal to generate a first signal a delay time after the occurrence of the leading edge and a second delay circuit which is responsive to the trailing edge of the command signal to generate a second signal a delay time after the occurrence of the trailing edge. A stylus control solenoid responds to the leading edge of the command signal for lowering the stylus into slidable contact with the surface of a capacitance disc record and further responds to the second signal for lifting the stylus from the record. A high frequency source is arranged to respond to the first signal by generating high frequency energy for application to the electrode of a capacitance detection stylus and further responds to the trailing edge of the command signal.

摘要： A recording system records a television video signal of 60 fields per second converted from a signal of the picture image content of a cinematographic film for projection at 24 film frames per second, in a manner such that the video signal has parts in each of which the picture image content of one and the same film frame continues during at least 4 fields thereof, along a spiral track on a rotating recording medium rotating at a rotational speed of 900 revolutions per second at a recording rate of 4 fields per revolution of the recording medium. The rotating recording medium thus recorded has a part on which the picture image content of one and the same film frame is recorded over a part of a length of the track corresponding to at least one revolution of the recording mediu

摘要： A cosmetic treatment apparatus comprises a discharge lamp, a capacitor, and a current controller. The capacitor supplies an electric current for the discharge lamp. The current controller controls the electric current flowing from the capacitor to the discharge lamp. In a first stage of the cosmetic treatment, the current controller performs a constant current control operation. In this operation, the current flowing to the lamp does not vary with variations of the capacitor voltage. In the end stage of the treatment, the current is lower, and it decreases with the capacitor voltage.
