Patent JP-H03162059-A (JP)
Title: Network controller
Inventor: KAWAI TOSHIHIKO
IPC: H04M11/00
Filed: 1989-11-21
Abstract: PURPOSE:To reduce current consumption by starting a control means when a polarity inversion signal is detected and a no-ringing call signal is detected and not starting the control means when no no-ringing call signal is detected. CONSTITUTION:A no ringing incoming circuit 11 detects polarity inversion and outputs a polarity detection signal and a timer circuit 23 starts counting. However, in this case since no ringing call signal is not detected, an effective tone detection signal DV resulting from a DTMF receiver 13 starting a CPU 16 is not outputted the CPU 16 continues the stop state. When the state continues and a timer circuit 23 counts a prescribed timeout time T2, a timeout signal is outputted. Thus, the timeout signal is fed to the no ringing incoming circuit 11 via an AND circuit 27 and the no ringing incoming circuit 11 reaches in line open state. Thus, the current consumption is saved.

Filed: 1989-11-21
Abstract: PURPOSE:To obtain the surface acoustic wave device having a large suppression quantity in a stopping area and a high performance by reducing the influence of an electromagnetic induction on a pattern with regard to surface acoustic waves connected in a multistage.

Title: Manufacture of semiconductor integrated circuit device
Inventor: TSUNODA TAKESHI
IPC: H01L21/265
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent an increase in a leakage current in a transistor, a variation of the threshold voltage of the transistor and the like without impairing the uniformity of the film thickness of a block oxide film, by a method wherein prior to an impurity implantation, the block oxide film is formed while being heated. SOLUTION: A block oxide film 26 is formed on the whole surface of a wafer while being heated, and thereafter impurities are implanted in a source/ drain 24 and gates 23A and 23B. After that, a Ti silicide film is formed by the same way as a conventional way. In such manner, by implanting the impurities in the source/drain 24 and the gates 23A and 23B after the film 26 is formed, the impurities implanted in the gates 23A and 23B do not experience a thermal history at the time of the formation of the film 26. Owing to this, as the penetration through the film 26 due to a thermal diffusion of the impurities is not generated, a variation of the threshold voltage of a transistor formed on the wafer is little.  Moreover, as the uniformity of the film thickness of the film 26 is never impaired, damage to the film 26, which can be generated in the manufacturing process of a semiconductor integrated circuit device, is little.
