Title: Sonar receiver
Inventor: KAMISE YOSHINORI
IPC: G01S7/527
Filed: 1994-03-11
Abstract: PURPOSE:To prevent reduction in processing gain by elimination of a band or target direction in the band from becoming impossible though the reverberative band is eliminated in order to suppress reverberative interference from an active system by a passive system in a sonar receiver to simultaneously perform active processing and passive processing. CONSTITUTION:A reduction B2 filter 3P is arranged in a passive system, and this filter output is inputted to passive filters (B1 to B3) 4P', and when a reverberative level is large, the reduction B2 filter 3P is turned on. Respective received signal average levels of passive and active systems are respectively detected by integral circuits 6P and 6A, and when a difference between both average levels becomes large, since the reverberative level can be regarded as negligible, this is detected by a comparing part 7, and the reduction B2 filter 3P is turned off. Thereby, a processing band of the passive system is expanded to the B1 to B3, and a purpose is made attainable.

Title: Complementary insulating gate inverter
Inventor: KIKUTA SHIGERU
IPC: H03K5/13
Filed: 1987-02-25
Abstract: PURPOSE:To obtain a delayed output waveform while a rise or fall time is short by providing the parallel body of the MIS transistor of an N channel and a P channel at the input side of a CMIS inverter circuit. CONSTITUTION:Since a transistor Tr4 is on when an input signal is a low level, the input signal rises and even the potential of an (a) point automatically rises. When the potential difference between the (a) point and an output signal becomes under the threshold of the transistor Tr4, namely, in a point t1, the transistor Tr4 comes to be an off condition, the (a) point comes to be a floating condition and the potential comes to be constant. At a time point t2 when the output signal is gradually reduced up to a time point t2 and the potential difference between the voltage and the input signal exceeds the threshold of a transistor Tr3, a transistor Tr3 comes to be an on condition at this time. Thus, the time at the time of the rise and at the time of the fall is not extended and a delayed output waveform is obtained with a quick change.

Abstract: Apparatus for deburring or other surface treatment of workpieces has a tubular housing with a set of axially parallel flexible, elastic or rigid rod- or wire-like components which define gaps and whose end portions are separately affixed to driven rotary end walls. The end walls wobble in synchronism with one another so as to move the components longitudinally while the components orbit about the axis of the receptacle. The workpieces which are admitted into one end of the receptacle are agitated and rotated as a result of rotation of the receptacle and move toward the other end of the receptacle due to reciprocation of components in parallelism with the axis of the receptacle. One or more nozzles admit jets of flames, solid, liquid and/or gaseous media which penetrate through the gaps between the components of the receptacle and treat the workpieces.
