Patent JP-H09298424-A (JP)
Title: Feedforward amplifier
Inventor: MISHIMA KAZUTOSHI
IPC: H03F1/32
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To minimize nonlinear distortion by providing a detector and a control circuit to monitor a distortion component and controlling a switch when the distortion component reaches a specified level or over so as to turn off an input to an auxiliary amplifier circuit. SOLUTION: A distortion signal component extracted by a distortion extract loop 1 is distributed to a detector 11 and a switch 13 by a signal extract device 10. The detector 10 detects a received signal and provides an output to a control circuit 12. The control circuit 12 monitors a detection output from the detector 11 and throws the switch 13 from an input of an auxiliary amplifier circuit 15 into a position of a terminator 14 when the detection output reaches a specified level or over thereby preventing an excess signal level from the distortion extract loop 1 from being given to the auxiliary amplifier circuit 15. Thus, even when the amplitude and the phase of a residual carrier level due to deviation in the distortion extract loop are changed optionally, since an absolute level given to the auxiliary amplifier circuit 15 is monitored, the nonlinear distortion is minimized.

Title: Detecting device for abnormality of recording medium
Inventor: OSHITA SHINICHIRO
IPC: B65H7/08
Filed: 1994-05-26
Abstract: PURPOSE:To surely detect an obstacle such as the skew running and corner folding of a recording medium by inexpensive formation. CONSTITUTION:In a case where a paper sheet is normally carried, the tip of the paper sheet 22 abut simultaneously against every actuator 14, which are therefore energized by the paper sheet 22 and wholly rotated in a direction designated by the arrow C to open the proceeding path of light, and the light issued from a light emitting element 16 is received by a light receiving element 18, and an ON signal is sent to a judging means. The output of the ON signal is maintained until the paper sheet 22 passes through the actuator 14. On the other hand, since in the case where the paper sheet 22 runs on the skew, or its corner is folded, the tip of the paper sheet does not abut against all the actuators 14 at the same time, a timing when the ON signal is outputted is delayed. Thus the abnormality of the paper sheet 22 can be detected through a single sensor 24 composed of the light emitting element 16 and the light receiving element 18 by measuring the continuous time of the output of the ON signal through the judging means.

IPC: H01L29/40
Filed: 1983-06-22
Abstract: PURPOSE:To avoid the direct irradiation of a semiconductor element with electromagnetic wave energy by covering the upper surface of a semiconductor substrate wherein the element is formed with a grounded conductive layer.

Title: Socket contact
Inventor: SHINMYO MINORU
IPC: H01R13/115
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a thin socket contact capable of securely pinching a pin contact for fixation. SOLUTION: In a box type socket contact having four surfaces of a bottom surface part 2, a first side wall part 3, a second side wall part 4 and a spring base part 5, the spring base part 5 is formed with a recessed part, and an inhibit part 8 continuously formed to the second side wall part 2 is inserted into the recessed part from outside. With this structure, dimension of a socket contact in the height direction can be reduced. A spring contact part 6 is pushed by the pin contact and deformed, but since an excessive displacement preventing part 5B of the spring contact part 6 is positioned in the recessed part, a dimension L2 between a load point 6B of the spring contact part and an abutment part 6C corresponding to the excessive displacement preventing part 5B is shorter than that of the conventional one.  Consequently, since the spring contact part is hard to be deformed after the abutment part contacts with the excessive displacement preventing part 5B, the pin contact is securely pinched for fixation by a V-shaped part 6A of the spring part and an inverted V-shaped 2B of the bottom surface part.
