Title: Underwater acoustic response device
Inventor: KURODA KEIICHI
IPC: G01S15/74
Filed: 1987-06-09
Abstract: PURPOSE:To improve the reliability of a device by cutting off a path by an analog switch in a period of the time width of a single pulse and making the path conductive in other periods. CONSTITUTION:A pulse acoustic wave sent by an external sound source is inputted to a gain switching circuit 3 through a receiver 1 and a BPF 2. Then a pulse acoustic wave signal which is given an optional gain by the circuit 3 is passed through the analog switch 4, amplified 5, and sent 6. Then a level detecting circuit 7 outputs a rectangular wave signal 71 while a signal 51 extracted from the output signal of a power amplifier circuit 5 exceeds a reference voltage. This signal 71 is integrated 8 and outputted as a signal 81 corresponding to the time width T1 of the rectangular wave. Further, a pulse generating circuit 9 generates a single-pulse signal 91 with time width T2 much longer than the width of the pulse acoustic wave from the external sound source when the signal 81 corresponding to the time T1 exceeds the reference voltage. This signal 91 drives the switch 4 in a period of a high potential and the switch 4 is turned off while the signal 91 is on to cut off the signal from the circuit 3. Consequently, the acoustic wave is not sent by a transmitter 6 to prevent howling from being caused.

Title: Automatic dial device
Inventor: MORIKAWA KENICHI
IPC: H04M15/30
Filed: 1980-10-17
Abstract: PURPOSE:To enable to calculate the call fee automatically, even if no polarity inversion is obtained, by starting the calculation of call fee through an off-hook output, in an automatic dial device having the call fee calculating function. CONSTITUTION:After the transmission of a dial signal, when an opposing subscriber picks up a handset of a telephone set 15, a control section 2 starts the calculation of call fee through the reception of an off-hook detection output of a hook detection circuit 14 and displayed on a display device 6. When the call is finished and the handset of the telephone set 15 is hooked off, the hook detection circuit 14 detects it and informs it to the control section 2. If the polarity of the power supply of a station is inversed through the response of called party, the control section 2 once resets the call fee calculation started with the off-hook detection and the fee calculation is started from the point of time again. Thus, the calculation of call fee is made even for a private branch of exchanger which is impossible for the inversion of polarity.

Title: Thickening of metal tube
Inventor: IRIE TORU
IPC: B21J5/08
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively form a tube having a desired thickened part with cold working by forming an expanded part with inserting a punch having tapered part from one end of a tube and inserting the expanded part in a reduction die having tapered part. SOLUTION: A tube stock 1 is vertically arranged with holding one end 1a by a clamp 2. A punch 3 is descended by actuating a hydraulic cylinder 4 and is pushed into the other end part 1b of tube stock 1, the other end part 1b of tube stock 1 is expanded as well as thickened. When expanded by pushing in of the punch 3, the tube stock 1 is generally thinned by tensile load in the circumferential direction, but by setting a tapered angle of the tapered part 3c of punch 3 to the range of >=30 deg. to <60 deg., compression load in the axial direction is applied to the tube stock 1, thickening action is generated. Next, the reduction die 5 is descended by the hydraulic cylinder 6 and the expanded part 1c thickened in a tube 1d is pushed into a die hole 5a through a tapered part 5b.  By this method, the outer diameter is reduced to the same diameter or roughly same as the outer diameter of tube stock 1a.

Abstract: PURPOSE:To enable the same terminal equipment to be used in the ISDN network of different specification by discriminating the specification of the ISDN network by executing call originating operation by way of trial at the time of turning on device power supply, and executing the subsequent call originating operation on the basis of this discriminated result. CONSTITUTION:When the device power supply is turned on, this facsimile equipment discriminates whether or not the subscriber number of an ISDN line L2 is registered previously. If the subscriber number is registered previously, it uses this line, and calls its own equipment at the setting of G3 facsimile by designating its own equipment as a called opposite party destination. In this case, the subscriber number of the ISDN line L2 is designated in the information element 'incoming number' of a call setting message 'SETUP' to be sent, and simultaneously, in the information element 'transmission capacity', it is designated as '3.1 k audio'. But since there is the ISDN network of the specification that 'transmission capacity' is a 'voice' as well, a flag is provided in a system memory 8, and either of the two can be designated by this flag.
