Title: Digital audio circuit
Inventor: SATO MITSUE
IPC: H03M1/82
Filed: 1986-03-05
Abstract: PURPOSE:To make the conversion level constant independently of the change in a sampling frequency by switching a resistor deciding a reference current value corresponding to the clock frequency in a digital audio circuit using an integration system D/A conversion circuit and an A/D conversion circuit. CONSTITUTION:A controller 10 controls a switch 11 to switch the sampling frequency and the clock frequency from a clock generator 8 and a 1/2 frequency divider fed to a signal processing LSI 4. Further, the controller 10 controls a switch 12 corresponding to the clock frequency to switch resistors 20, 21 deciding the reference current of the integrated current of an integration capacitor 18. Thus, the reference current value of the reference current source 16 is switched corresponding to the clock frequency. Thus, the conversion level is made constant independently of the change in the sampling frequency.

Title: Rotary head type digital audio reproducing device
Inventor: YOKOZAWA SEIICHI
IPC: G11B15/467
Filed: 1987-03-03
Abstract: PURPOSE:To prevent an erroneous sampling by a false sink signal and to realize stabilized tracking control by forming the signal expressing a tracking dislocation amt. by the level of the crosstalk of the pilot signals of both adjacent tracks subjected to sampling with the detection time of the pilot signal as the reference. CONSTITUTION:The signal expressing a tracking slippage amt. is formed by the level of the crosstalk of the pilot signal of one part of adjacent tracks subjected to sampling with the detection time of the pilot signal as the reference and that of the crosstalk of the pilot signal of the other part of adjacent tracks and the feeding of signals to a capstan servo is controlled by whether the detec tion of the pilot signal on-track is correctly performed or not. A correct tracking can thus be taken without malfunctions even if a false sink signal by overwrite, for instance, is located before an actual sink signal. In the case of no pilot signal on-track being detected the tracking control by signals is not performed to prevent the disturbance in tape traveling.

Abstract: PROBLEM TO BE SOLVED: To simplify fitting and removing work of an electric feed line, by supporting, with a supporting member, an electric feed line retaining member of roughly U-shaped whose upper surface is open, which is formed so as to be capable of fitting the electric feed line. SOLUTION: The inner diameter W of an inner groove 13 of an electric feed line retaining member 1 is formed so as to be almost equal to the diameter of an electric power line 4, and the opening width (w) of its upper surface is formed so as to be a little smaller than the inner diameter W of the electric feed line retaining member 1, or the diameter of the electric feed line 4. The electric feed line 4 is pressed in the inner groove 13 from the above of the electric feed line retaining member 1, and both side pieces 12 of the electric feed line retaining member 1 is expanded outward by its elasticity to fit and retain the electric feed line 4. A supporting member consisting of a frame 2 and a bracket 3 for supporting the electric power line retaining member 1 are formed integrally below the electric feed line retaining member 1.

Abstract: PURPOSE:To eliminate an interference component even when the arrival direction of an interference signal coincides with that of a main signal by synthesizing the main signals received at plural antennas with negative phase and same amplitude with each other, and compensating it by forming the interference signal with high purity. CONSTITUTION:A reception signal received by a sub antenna 4, after the main signal being set at the same amplitude as and the negative phase with the main signal of the reception signal received by the antenna 1 by a variable amplitude circuit 11 and a variable phase circuit 12 controlled by a control circuit 141 on which the relative amplitude and relative phase of the reception signal and the reception signal of the antenna 1 are added, is supplied to a synthesizer 14 with the reception signal received by the antenna 1, and the interference signal with the high purity in a remaining form from which the main signal is negated is extracted from the synthesizer 14. And a signal via a synthesizer 10 and an extracted interference signal set at the same amplitude as and the negative phase with the interference signal of the signal similarly are synthesized at a synthesizer 19, and since no antenna which receives the interference signal is used, the interference signal can be eliminated even when the arrival direction of the interference signal coincides with that of the main signal, then, automatic compensation can be performed.

Title: Optical scanning device
Inventor: AKATSU KAZUHIRO
IPC: G02B26/10
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide an optical scanning device with which a prescribed spot diameter is provided even when there is the eccentricity of a photosensitive body by movably holding the optical scanning device and keeping a distance between a prescribed spot on the optical scanning device and a position to be irradiated with light on the surface of the photosensitive body within a fixed error range at all the time. SOLUTION: An optical scanning device 7 is arranged so as to be rotated with a shaft 9 as a center. The surface of a photosensitive body 5 is contacted to this optical scanning device 7 by a positioning roller 11 so that the distance between the surface of the photosensitive body 5 and the optical scanning device 7 can be fixed at all the time. Since the positioning roller 11 is pressed onto the surface of the photosensitive body 5 by the gravity of the main body of optical scanning device 7 or the force of a spring or the like from the outside, even when the shape of the photosensitive body 5 is changed, the distance between the photosensitive body 5 and the optical scanning device 7 can be accurately fixed.  In this case, when the position of the positioning roller 11 and the lengthwise position of scanning light 8 and 12 on the photosensitive body 5 are almost fixed, the distance between the photosensitive body 5 and the optical scanning device 7 can be exactly kept.

Abstract: PURPOSE:To improve the reliability of a data transmission system by providing a mistransmission preventing means to prevent such a case where a central unit transmits the untransmitted change terminal data on a reading terminal already stored in a memory means for change terminal data to a host computer. CONSTITUTION:A transmission and flag FD is set into the change data in order to prevent the misjudgment of a host computer 1. Then the flag FD is set for the untransmitted change data in case this data contains the change data on a terminal whose registration is cancelled as a change terminal or if the past untransmitted change data on the change terminal is detected when a central unit 3 receives a request from the computer 1 for the terminal data on the present time point of the change terminal earlier than the change data. Thus the transmission of the change data is inhibited to the computer 1. This improves the reliability of a data transmission system.
