Title: Recording and reproducing device
Inventor: KAMINAKA HIROYUKI
IPC: G11B20/02
Filed: 1991-03-15
Abstract: PURPOSE:To prevent the occurrence of a mode which is out of definition by converting an indiscriminatable mode into a prescribed sound mode with an audio mode conversion circuit when the indiscriminatable mode is generated in decoding a regional audio mode discriminating signal by rewriting one part of plural audio recording regions. CONSTITUTION:In the case of four-channel postrecording, four-channel audio signals are impressed upon input terminals 1-4, and if their contents are two stereo systems, a four-channel audio mode discriminating signal is impressed upon an input terminal 5. The two-channel audio mode discriminating signals are impressed upon recording signal processing circuits 10 and 11 of audio recording regions 1 and 2 respectively by an audio mode discriminating signal conversion circuit 7. The audio signals of channels 1 and 2 and the two-channel audio mode discriminating signal 8 are converted into a recording signal of the audio recording region 1 by the circuit 10, while the audio signals of channels 3 and 4 and the two-channel audio mode discriminating signal 9 into a recording signal of the audio recording region 2 by the circuit 11, and then they are recorded in the regions 1 and 2 respectively. Consequently, no indefined mode is generated under reproducing, because of rewrite for all channels.

Title: Pulse rotor for rotation detecting device
Inventor: MATSUURA NOBUHISA
IPC: G01P13/04
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To detect the direction of rotation of a rotating member by one rotation detecting device by grouping pitches at three locations or more between four characteristic variable parts or more adjacent circumferentially into one group, differentiating the size of the three pitches or more from one other, and arranging each pitch regularly on a single circle. SOLUTION: A plurality of protruded parts 2a and 2a which are characteristic variable parts are provided on a single circle located at the center of the rotation center axis of a rotating member at the circumferential edge part of a pulse rotor la for a rotation detecting device. Pitches P1 , P2 , and P3 at three locations between the protruded parts 2a and 2a are differentiated in size, and the pitches P1 , P2 , and P3 are grouped into one. The rotor 1a is rotated together with the rotating member. At this time, the protruded parts 2a and 2a opposed to the detecting part of a sensor are circumferentially displaced to change the output voltage of the sensor. In this case, as the pitches P1 , P2 , and P3 are different from each other, time intervals in the changes of the output voltage are different.  As waveforms different from one another occur at the time when the rotating member is rotated in a normal direction and in a reverse direction, it is possible to determine the direction of rotation.

A clock pulse emerges at the output Vout while the terminal voltage of the capacitor C is kept at a level between 1 and 0. The digital value of the input voltage is calculated by measuring the period of the clock pulse.
