Filed: 1985-01-11
Abstract: PURPOSE:To obtain a simple configured and inexpensive video signal detection circuit by constituting to compare a detecting output voltage which is outputted from the AGC detection circuit of an AGC loop circuit in a video tape recorder at a comparator. CONSTITUTION:An AGC detection circuit 12 generates a smoothed signal by detecting the pedestal part and the white peak of a video signal 100 inputted to the AGC circuit 11 and settles the level of a video signal inputted to the AGC detection circuit 12 by controlling the gain of the AGC circuit 11 through this smoothed signal. Hereupon, a comparator 13 compares the detecting output voltage inputted from the AGC detection circuit 12 with a reference voltage and it is detected that there is no input video signal because the output of a video signal detecting signal 500 is suppressed to a low level when the detecting output voltage is higher or lower than the reference voltage. Accordingly the configuration of a circuit is simplified as stated above.

Title: Fabrication of tunnel transistor
Inventor: UEMURA TETSUYA
IPC: H01L29/68
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for fabricating a tunnel transistor having a high quality junction interface. SOLUTION: After a drain layer 3 is formed using a mask 11 having a void 12, the mask 11 is removed and a channel layer 5 touching at least the side face of the drain layer 3 is formed. Consequently, the side face of the drain layer 3 can be exposed without requiring a step for exposing the side face of the drain layer 3 through etching. Since the channel layer 5 is formed after the mask 11 is removed in a deposition system, residual impurities on the tunnel junction interface between the side face of the drain layer 3 and the channel layer 5 can be reduced as compared with a conventional method.

Title: Pig-tailed semiconductor laser device
Inventor: YANASE TOMOO
IPC: H01S5/00
Filed: 1984-01-10
Abstract: PURPOSE:To reduce the noise due to return light by reduction of the amount of return light by a method wherein a pig-tail containing a fiber type polarization filter and a birefringence optical fiber is arranged in such a manner that the output end of a semiconductor laser optically couples with one end of the pig- tail. CONSTITUTION:When a semiconductor laser beam is made incident to the pig- tail 14 so that the polarization direction 22 of an emitted beam of the semiconductor laser 11 may become coincident with the stress direction of the polarization filter 18 of the pig-tail 14, it passes through the first section 18 as it is because of no attenuation of TE waves. Next, this beam is made incident to the second section 19, where the length is 2n+1L/4; therefore, the beam comes to the state of circular polarization 24 at the emission end. A return light reflected on this emission end, on returning to the connection part of the first section 18, becomes TM waves perpendicular to the stress direction of this section 18. Since the TM waves are attenuated by a metal film 17 during passing through the secion 18, the light hardly returns to the semiconductor laser 11.

Title: Pre-distortion device and method
Inventor: HASEGAWA TAKESHI
IPC: H04B1/62
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a device for operating precise pre-distortion without increasing the scale of a circuit. SOLUTION: Pre-distortion is operated by using a pre-distortion function calculated from the inverse function of the input and output characteristics of a power amplifier for holding the inclination of a small power part with satisfactory linearity of the input and output characteristics for linearizing the input and output characteristics. At the time of digitizing the pre-distortion function, and registering it in a table, a difference between the pre-distortion function and a function expressed as y=x is calculated, and a function indicating the difference is registered in a function table. Then, the part of the pre- distortion function whose inclination is small is made equal to the function expressed as x=y. Thus, a quantization error can be reduced by digitizing only the difference between the pre-distortion function and the function expressed as y=x.
