Title: Busy tone detection system
Inventor: KOYAMA KAZUHIKO
IPC: H04B3/23
Filed: 1991-09-09
Abstract: PURPOSE:To surely detect a busy tone from an opposite station even when a holding tone or the like is sent to the opposite station by eliminating a stray signal in a 2/4-wire conversion circuit. CONSTITUTION:An office line trunk 1 is subject to holding, a holding tone from a holding tone source 8 is converted into a signal for 2-wire at a 2/4-wire conversion circuit 2 and it is sent to a public network 9. An echo canceller 5 eliminates a stray signal caused when the 2/4-wire conversion circuit 2 converts a signal for 4-wire into the signal for 2-wire. A frequency detection circuit 3 is provided with a function for detecting a frequency the same as that of a busy tone, detects an intermittent period of the busy tone coming from the public network 9 and sends it to a controller 4. When the controller 4 detects the same intermittent period as that of the busy tone, the controller 4 informs it to a central controller 7 that the busy tone comes to the trunk 1.

Title: Waveform compensation device and retry method using this device at the time of read error
Inventor: IIDA MITSUKO
IPC: G11B20/18
Filed: 1989-09-05
Abstract: PURPOSE:To improve an error rate when data is read by providing a means changing a rate attenuating an original compensation signal in a wave form compensation part when a read error is detected in an error detection processing part for a waveform compensation part. CONSTITUTION:The switch change over part 34 of an equalizer 23 changes over a switch part 33 from a switch SW1 to switches SW2, SW3 and SW4 by a retry instruction from a controller 26. Since a resistance R1 is changed to resistances R2, R3 and R4, an equalization quantity is sequentially switched and the waveform of the compensation signal inputted to the negative terminal of a differential amplifier part 11 is changed. In the differential amplifier part 11, a data signal inputted to a positive terminal is compensated thin by the waveform of plural kinds of compensation signals inputted to the negative terminal, and it is outputted to an A/D converter 25 through LPF 24. Thus, the peak width and the peak position of a data signal are changed and the rate that the A/D conversion part 25 detects the accurate data signal is improved since the waveform of the data signal is deformed thin into plural kinds.

Abstract: PROBLEM TO BE SOLVED: To correctly detect a moment when an object to be measured starts rotating, by setting a rotation sensor for detecting a rotation of a floating part to the floating part which is freely supported to an engaging part and rotates together with the object to be measured (screw or bolt). SOLUTION: An engaging part 2 is engaged with an object 1 to be measured in a manner to be able to transmit a torque, and a floating part 3 which is a different body from the engaging part 2 is freely supported at the engaging part 2. An urging means 9 (spring or the like) urges the floating part 3 in an axial direction. A rotation sensor 6 mounted to the floating part 3 detects a rotation of the floating part 3. A torque sensor 7 set to a lever part 5 detects a torque acting to the engaging part 2. The engaging part 2 is engaged with a head part of the object 1, and a grip part 11 is held by a hand thereby to turn a wrench main body 13 and apply a torque to the object 1. The rotation sensor 6 detects the rotation of the floating part 3 and the object 1, not a rotation of the engaging part 2. Therefore, even when the object 1 rattles to the engaging part 2, a start point and an amount of the rotation of the object 1 can be detected correctly.
