Title: Fsk signal demodulator
Inventor: TSUBOTA KAZUHIRO
IPC: H03K5/00
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To surely and stably demodulate an NRZ(non-return to zero) signal even when an FSK(frequency shift keying) signal includes timewise companding components. SOLUTION: A signal processing means 3 samples sequentially a waveform- shaped FSK signal 2 by a clock signal 9, inverts specific sample data with respect to combinations of a series of sample data and provides an output of a serial of sample data including the inverted data sequentially. A delay detection means 5 applies delay-detection to an output signal 4 from the signal processing means 3 and a digital LPF 7 eliminates an undesired signal from an output signal 6 of the delay detection means 5 to obtain an NRZ signal.  Thus, even when timewise companding components are included in the FSK signal 2 subject to waveform shaping, since the signal processing means 3 relaxes or eliminates the timewise companding components, even when the FSK signal includes the timewise companding components whose period is less than a k-period of the clock signal or below, the NRZ signal 10 is surely obtained from the output of the digital LPF.

Title: Liquid-level display tube
Inventor: TANAKA HIROYUKI
IPC: G01F23/02
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To easily detect a liquid level by providing a display mark on the side surface of a liquid-level display tube communicating with a process liquid tank through a transparent body. SOLUTION: When a liquid level 115 is lower than the lower end of a display mark 116a, the display mark 116a is thin and not conspicuous as shown in (A). However, when the liquid level 115 rises up to a position of the display mark 116a, the display mark 116a as far as the liquid level 115 is magnified as a liquid level display tube 114 which contains a process liquid 118 acts as a convex lens, as shown in (B). Thus, a user recognizes excessive amount of process liquid 118 at a glance, and stops supplying the process liquid to prevent overflow of it.

Filed: 1988-12-02
Abstract: PURPOSE:To enable highly reliable flaw detection by a method wherein automatic flaw detection is performed with surface waves detected by making ultrasonic waves slantly enter an outer peripheral surface of a specimen. CONSTITUTION:A generating and receiving circuit 18 outputs low frequency driving signals according to an instruction from an arithmetic control circuit 20, emits ultrasonic waves having the same frequency as driving signals from a slanted angle probe 12, and transmits surface waves along a facial layer of a specimen 10.

The circuit 18 removes noise from the detection signal as well as amplifies the detection signal and supplies it to the circuit 20 via an A/D-converter 22. The circuit 20 processes an input signal and verifies that the surface wave is actually transmitted to a flaw-detection region as the specimen moves lengthwise while it automatically identifies existence of a defect on the surface or under the surface, and the results are output to a display/recorder 24 and a marker 26.

Abstract: PURPOSE: To attain transmission for the asynchronous transfer mode by keeping the relation of a frequency of a 2nd signal sent from a 2nd transmitter to be fixed to a frequency used, when a 1st signal from a 1st transmitter is received by a 2nd receiver. CONSTITUTION: A transmission signal t1 of an exchange PE is sent to a receiver R2 of a subscriber, in which the signal is mixed with a signal 12 of a local laser L2, the frequency of the mixed signal is turned to be an IF output signal. Furthermore, a signal t2 from the subscriber PS is fed to a receiver R1, in which the signal is mixed with a signal 11 of a local laser L1 to be an IF output signal. Then a frequency of the signal t2 is selected to be a fixed interval with a frequency of the signal 12, the frequency of the local laser L1 is not tuned and has a fixed interval with the frequency of the signal t1. Thus, complete double connection is attained by the signal t1, t2 and the signal t1 is locked to a reference frequency, and the signal t2 is locked to the signal t1 by using a single turning operation.

Title: Dry etching method
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/302
Filed: 1992-11-17
Abstract: PURPOSE:To improve a lower resist layer in base selectivity at etching in a three-layered resist process. CONSTITUTION:A lower layer 3 formed on an Al-Si-Cu layer 2 is etched with mixed gas of CO/Cl2/O2. CClx polymer as etching reaction product grows high in etching resistance taking in C-O bonds and car bonyl groups, so that a strong side wall protective film 6 is formed. By this setup, ions required for carrying out anisotropical processing can be lessened in impinging energy, so that the layer 3 is enhanced in selectivity to the Al-Si-Cu layer 2, and a sputtering redeposit layer caused by the layer 2 can be prevented from being generated. The deposit of CClx polymer can be lessened, so that this process is less contaminated. If sulfur compound gas such as S2Cl2 or the like is added, the process can be more lessened in contamination in combination with deposit of S (sulfur) and enhanced in selectivity.
