Filed: 1990-10-04
Abstract: PURPOSE:To minimize the changing quantity of the alignment of a steering roll and miniaturize the endless belt carrying device by providing an auxiliary roll which curves the belt carrying path between the steering roll and the roll next to the steering roll in the opposite side of the belt near the steering roll. CONSTITUTION:An auxiliary roll 5 is rotatably supported by a device frame supporting driven rolls 31 and 32 and drive roll 2 and is brought into contact with the outer peripheral surface of a belt 1 between the roll 31 and a steering roll 4 and is arranged so as to curve the belt carrying path between the rolls. In addition, the belt 1 is moved in the width direction by the change of the alignment of the roll 4 at the speed according to the quantity of the change. Since the auxiliary roll 5 is thus arranged, the winding angle of the belt 1 to the roll 4 can be set largely as a result, the belt 1 can react quicker and more smooth against the change of the alignment of the roll 4. Even the small changing quantity of alignment, therefore, makes it possible to properly control the width directional movement of the belt 1.

Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To accurately detect a phase of a delay wave at a current point of time even when a time requiring to detect a delay wave to be demodulated. SOLUTION: Data R spread-modulated by a spread code having a code length being a multiple of N of a correlation length are fed to an input terminal 11. A reference phase generating section 14 generates data RT representing a tip number being a reference to detect a phase of a delayed wave included in the received data R. A phase detection section 15 detects a phase of the delayed wave by applying inverse spread to the received data R while sequentially revising a phase of the spread code and detects a relative phase between the delayed wave and the data RT by obtaining a difference between the data representing the detected phase and reference chip number data RT. Demodulation sections 16(1), 16(2) add the data RP1, RP2 representing the relative phase and the reference tip number data RT to obtain the absolute phase of the delayed wave to demodulate the delayed wave by using the spread code having the absolute phase to apply inverse spread to the received data R.

Title: Communication circuit
Inventor: SUZUKI SATORU
IPC: H04B3/03
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To improve the noise characteristic by providing an output stabilizing means and a noise elimination means in a communication circuit. SOLUTION: A communication signal 100 that is isolated from a communication line by a pulse transformer 1 is applied to resistors 5, 6, 7 and fed to a transmission reception circuit 4 via resistors 2, 3. Then the transmission reception circuit 4 detects the communication signal 100. In this case, noise directly received from the pulse transformer 1 is given to a point of ground level via capacitors 10, 11 being a noise elimination means 52, then the noise is eliminated. Since an output from the pulse transformer 1 takes a ground level as a reference level by providing resistors 5, 8, 9 being an output stabilizing means 51, the output of the pulse transformer 1 is made stable. As a result, since the output of the pulse transformer 1 is made stable and noise is eliminated, the noise characteristic is improved.

Title: Deflector roll for high tension rolling mill
Inventor: KAMIMARU AKINOBU
IPC: B21B39/08
Filed: 1993-10-25
Abstract: PURPOSE:To elongate the life of a roll by making the surface hardness of a deflector roll base material into a specific value, further providing a thermally sprayed layer made of WC as its main component on its surface, and making the surface's average roughness into a specific value. CONSTITUTION:The base material surface hardness of a deflector roll 3 is made in 85+ or -3 Shore hardness HS. The thermally sprayed layer made of tungsten carbide as its main component is provided on the surface, and the surface's average roughness Ra is made in 1+ or -0.3mum. Because the hardness of the base material surface area is made over than 82 Shore hardness HS, locally deforming is hardly generated, and the thermally sprayed film can be prevented from stripping. Because the base material's surface hardness is made under 88 Shore hardness HS, the reduction of the tight adhesion strength of the film caused on the hardness increase can be controlled within a level without practically troubling. The surface roughness of the WC thermally sprayed film is generated with slips if it is too fine, and flaws are generated on the steel strip if it is too rough.

IPC: E03B3/32
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To remove a deposit in a culvert type intake device including a conduit, and to supply good quality water stably for a prolonged term by piping pipes to the inside and/or the outside of an intake section for the conduit and installing a backwash line supplying a Jet flow towards the intake section at the time of the washing operation of the conduit. SOLUTION: A conduit backwash line 12 is branched from a water-supply line 21 from the upstream spot of a water-supply line21-shaped valve V11, piped through the insides and/or the outsides of conduits 11 at specified spots, and projected from the conduits 11 from intake sections 11b and connected to a drainage line 19 or a water storage tank 15. When a valve V16 is closed at the time of backwash operation, a valve V15 is opened and water is flowed into a backwash line 12-1 and the valve V15 is closed suddenly, a high-speed flow is ejected as jet flows from perforated pipe sections 12a in response to the intake sections 11b of the conduits 11 in the backwash line 12. Accordingly, deposits in the conduits 11 and in a peripheral culvert section can be removed.  Stable intake for a prolonged term is carried out without requiring a hand by periodically conducting the above-mentioned process.
