Title: Voice quality assuring system for private branch exchange of public exclusive connection
Inventor: KIKUCHI OSAMU
IPC: H04Q3/58
Filed: 1992-04-23
Abstract: PURPOSE:To improve the talking voice quality by providing an automatic gain controller and an echo canceler between the central office line trunk and private line trunk of a private branch exchange PBX. CONSTITUTION:An echo canceler 6 erases the echoes which are produced when the voice signals sent from a private line 2 are returned by a 2/4-wire converting circuit 8 of a central office line trunk 4 and a 2/4-wire converting circuit 10 included in an office exchange of a public network 1. An automatic gain controller 7 is included in a channel reaching to the line 2 from the network 1 and keeps a fixed talking level. That is, the reduced talking level is compensated by the controller 7 for the voice signals sent from the network 1. Thus the compensated voice signals are sent to the line 2. Furthermore the voice signals sent to the network 1 from the line 2 are erased by the canceler 6 even though these signals are returned by both circuits 8 and 10.

Title: Magnetic disk device
Inventor: KISO MATAICHIRO
IPC: G11B25/04
Filed: 1985-05-14
Abstract: PURPOSE:To set the dislocation of a magnetic disk in the same direction by increasing the surface pressure owing to the tightening force of a large diameter volt with the use of volts having different diameters, and decreasing the surface pressure owing to the tightening force of the small diameter volt. CONSTITUTION:The small diameter volts 11A-11C are disposed at positions symmetric with the disposing positions of the large diameter volts 9A-9C with respect to straight lines Y1-Y2, which intersect orthogonally with straight lines X1-Xn, through a spindle shaft 23. When the temperatures of a base 1 and a housing 21 are raised due to the heat produced by the load current of a spindle motor 2 or the heat caused by a mechanical loss arising from a bearing, the slide of a joint part 8A between the base 1 and the housing 21 occurs always at the side of the small diameter volt, because the tightening force of the large diameter volt is larger than that of the smaller diameter volt. Thus the direction and quantity of the slide in the joing part becomes always constant, thereby obtaining a highly accurate device.

IPC: B41J7/96
Filed: 1987-04-28
Abstract: PURPOSE:To ensure that even when only one of a multiplicity of pins is broken, the breakage of the pin is detected securely and speedily, by providing a pressure sensor on the side of a platen against which the tip of a printing pin collides at the time of printing, and a testing means for checking whether a pressure signal due to the collision of the printing pin is generated from the pressure sensor within a predeterined period of time from the time of the generating of a driving signal for the printing pin. CONSTITUTION:When a printing pin strikes a pressure sensor 13 in response to a driving signal from a CPU 1, a pressure signal is generated immediately after the driving signal, and a flip-flop 15 set by the driving signal is immediately reset. After the flip-flop 15 is reset, a test signal is generated. In this case, a discriminating circuit 17 judges that the printing pin is normal When the driving signal from the CPU 1 is applied for a broken printing pin, the pin does not strike the sensor 13, so that no pressure signal is generated. In this case, the circuit 17 judges that the printing pin is broken, and supplies the CPU 1 or other controlling part with a signal indicative of this condition.

Abstract: PURPOSE:To measure a frequency characteristic exactly, by providing a means for coupling an exit light beam of a semiconductor laser, with an optical path to be measured, through a liquid crystal to which an AC electric field has been applied. CONSTITUTION:As voltage of a signal generator 11 is varied, a DSM scattered state is varied, a mode power distribution of a laser beam which is made incident to a fiber cable 4 to be measured, and is propagated is varied in each time, by which a speckle pattern of the section of the fiber is varied. In case when it has been observed by a time constant which is much longer than a period of an applied voltage signal, the speckle pattern of the fiber section is averaged. Accordingly, when a time constant for measuring a frequency characteristic of the optical fiber cable 4 is made much larger than a period of a voltage signal which is applied to a liquid crystal film 9 generated by the signal generator 11, the speckle pattern in case of measuring the frequency characteristic of the optical fiber cable 4 is averaged equivalently. Therefore, the reproducibility is elevated.

Title: Power supply circuit wherein power consumption is reduced in standby state
Inventor: CHIYOU KICHIYOU
IPC: H04N5/76
Filed: 1994-05-19
Abstract: PURPOSE: To save power consumption by forcibly reducing an output voltage at a secondary side by the control of a microprocessor, when a load equipment is in a standby state and controlling the amount of feedback of a feedback part. CONSTITUTION: In a standby state, 12V at a terminal B of a secondary side rectifying part 104 is dropped to 5V by a 5V-regulator 110 and then is applied to a microprocessor 109, thus continuously operating the microprocessor 109. Then, since a diode D1 can be turned on due to the conduction of a transistor Q2, a voltage applied to a terminal C of the secondary side rectifying part 104 can be forcibly fed back through a route of a resistor 5, a feedback part 106, and the diode D1, thus forcing a voltage at the secondary side to be dropped and hence reducing power consumption to less than 10 W and enhancing the reliability in TVCR.
