    摘要: An input device for moving a cursor to a desired point in a display has a sliding member which moves on a two dimensional coordinate system, a location detector which electrically detects the location of the sliding member within that coordinate system, and a switch to allow data entry in correspondence to the desired point indicated in the display corresponding to the position of the sliding member, in response to depression of the sliding member in a direction perpendicular to the plane of the coordinate system.

    摘要: A recording and/or reproducing apparatus is disclosed in which informational signals are recorded and/or reproduced by irradiating an optical disc 202 with a light beam from an optical pick-up device 1 through an recording and/or reproducing opening 205 which is formed in a disc cartridge 202 which rotatably houses an optical disc 203. The optical pick-up device 1 which is used for the recording and/or reproducing apparatus comprises a light source and an objective lens 5 for converging the light beam from the light source upon the signal recording area of the optical disc 203. When recording and/or reproducing of informational signal on and/or from the optical disc 203 is performed by the optical pick-up device 1, only the objective lens 5 is moved into the disc cartridge 202 via the recording and/or reproducing opening 205 formed on the disc cartridge 202 to shorten the distance between the objective lens 5 of the optical pick-up device 1 and the disc 203.

    摘要: A tracking servo signal is generated for use in an optical disc pick-up system, being particularly advantageous for use when the depth of the pits is greater or less than one-fourth the wavelength of the light beam used to read the disc, in which case diffraction patterns formed by reflected light beams are not symmetric on a photo-detector and typically result in DC-shifted tracking error signals. A first tracking error signal is generated from selected output signals of a number of light-receiving areas of the photo-detector and a second tracking error signal is generated by combining output signals from these light-receiving areas in a pattern different than that used in generating the first tracking error signal. These two tracking error signals are combined so that the resultant signal forms a tracking servo signal that has substantially no DC component.

    摘要: A MOS-type FET (field effect transistor) amplifier includes a pair of P-channel and N-channel output stage MOS-type FETs which are ON-OFF controlled by a pulse signal and an inductive load. Each reverse current caused by the inductive load is shunted by a diode connected between the drain and source of each of the MOS-type FETs. An additional pair of diodes are provided in the drain-source circuits of the MOS-type FETs so as to prevent each reverse current flowing through respective substrates of the MOS-type FETs.

    摘要: A monostable multivibrator having a novel four terminal semiconductor device with a generally V-shaped emitter grounded current amplification characteristic. Means are provided to bias the operation of the device to a low point on the characteristic, to provide a trigger signal to the base of the semiconductor device for placing the device in a conducting state and, through the operation of a capacitor coupled between the gate and collector terminals, to shift the operation of the device to a high level on the emitter-grounded current amplification characteristic thereby sharply decreasing the output voltage obtained at the collector. Discharge circuit means are provided for the capacitor to gradually reduce the gate voltage and to shift the operation of the device back to the low circuit point thereby reducing the collector current and suddenly increasing the collector voltage.
