Title: Method for lining inner wall surface of pipe
Inventor: TANAKA TOSHIAKI
IPC: B05D7/22
Filed: 1987-04-02
Abstract: PURPOSE:To drastically improve the lining efficiency by enabling the lining without completely drying the inner wall surface of the pipeline to be renewed. CONSTITUTION:A high-viscosity epoxy resin paint 5 capable of being cured in water is accumulated in a pipe 1 to be treated, and an elastic pig 6 is arranged at the rear of the paint. A pressure difference is generated between the space behind the pig 6 and the space before the paint 5, and the pig 6 and the paint 5 are integrally moved toward the outlet end of the pipe 1 to be treated while pushing ahead the water W retained in the pipe 1 by the paint 5. Namely, since the epoxy resin paint capable of being cured in water is used as the paint, the water in the pipeline need not be carefully removed by drying, and hence the efficiency in renewing the pipeline is drastically improved.

Title: Psk circuit
Inventor: MATSUOKA HIDEKI
IPC: H04N11/04
Filed: 1994-04-20
Abstract: PURPOSE:To suppress a side lobe without the need for a roll-off filter by selecting a corresponding kind of a waveform among transmission data waveform patterns for plural filtered transmission data. CONSTITUTION:Transmission data are sampled at a pattern discrimination section 4 by using a data series in plural bits for one block, the sampled data are given to a shift register 5, in which the data are converted into parallel data and they are given to a control section 6. The control section 6 reads waveform conversion data corresponding to the data in plural bits from a ROM 7 and gives the read data to a D/A converter 8. The D/A converter 8 provides sequentially the output of waveform data based on the received data and a low pass filter 9 applies waveform shaping to the outputted data. Thus, a conventional analog roll-off filter is not required, the number of components is reduced to reduce the cost, the circuit scale is made small and then the power consumption is reduced.

Title: Apparatus for adjusting optical system of pulse encoder
Inventor: TAKEKOSHI YOSHITAKA
IPC: G01D5/36
Filed: 1987-04-04
Abstract: PURPOSE:To easily adjust a position with high accuracy without performing manual operation, by sending a position correcting order to a servo amplifier performing operation on the basis of the analytical data of a wave form. CONSTITUTION:A wave form analytical part 1 detects the data relating to the shift with respect to an ideal wave form from the output wave form of a pulse encoder 5 when the slit part of the pulse encoder 5 is moved. A computer 2 operates a way to have to move a light emitting part or four quantity- of-receiving light detectors from the detected data in order to allow the output wave form of the encoder 5 to approach the ideal wave form to output a position correcting order. In response to this output, a servo amplifier 3 supplies a drive current to an optical system driving part 4. As a result, the ideal wave form is obtained from the encoder 5.

Abstract: PURPOSE:To join smoothly and quickly the rear end of a preceding rolled material and the front end of a succeeding rolled material by providing sloped end faces by pressing to said front end and rear end, butting the two end faces on different planes and conducting high frequency current thereto while pressurizing the butt surfaces on the same plane. CONSTITUTION:The rear end of a preceding rolled material 10a and the front end of a succeeding rolled material 10b are pressed on the inlet side of a roughing mill or finishing mill to slope the respective end faces 11 with an angle of inclination theta by about 2-4 deg. relative with the perpendicular plane. The two end faces 11 are then butted and a V-shaped step is provided by a lifting cylinder 44 so that the end faces are butted on different planes. Contact chips 45 are brought into contact with the side faces and high frequency current is conducted thereto to heat a welding point 111. The welding point is pressed by a press contact roll 43 to start joining. The cylinder 44 is thereafter gradually descended and the point 111 is moved successively toward the transverse direction. The roll 43 is moved in follow up to said movement. The preceding and succeeding rolled materials are thus smoothly and quickly joined and rolling efficiency is improved.

Title: Compensating system for identification of cross polarization
Inventor: MIYAJIMA TAKAHIKO
IPC: H04B7/00
Filed: 1979-07-02
Abstract: PURPOSE:To compensate the waveform distortion, by controlling the amplitude of the base band signal at polarized wave side, in demodulating the transmission wave by using the reference carrier different in phase by 90 deg. CONSTITUTION:The horizontal polarization signal is fed to the terminal 41 and the vertical polarization signal is to the terminal 42. Detectors 50, 51, 52 perform demodulation with the signal having the phase diference by 90 deg. from the phase shifter  49. Thus, the first and second series signal of the horizontal polarization demodulation and those of the vertical polarization demodulation are obrained. The output of the phase detector 50 is fed to the synthesis circuit 56, and the correlation between the first and second series signals of the vertical polarization from the circuits 54 and 55 is taken at the correlating units 57 and 58 to be the control signal for the amplitude control circuits 61 and 62. The synthesis circuit 56 synthesizes the first and second signals of the vertical polarization in amplitude-control and outputs the first series base band signal of horizontal polarization without vertical polarization components.

Title: Protection system of control signal memory against overflow
Inventor: FUKUDA EISUKE
IPC: H04W88/08
Filed: 1982-05-17
Abstract: PURPOSE:To prevent a control signal memory from overflowing owing to noise without increasing its capacity and the number of central processors, by writing only control data on a normal subscriber station in the control signal memory, and inhibiting the writing if the subscriber station is disconnected. CONSTITUTION:The control data is provided with an area 4 for indicating significance or insignificance; ''1'' ''1'' is set for the significance and ''0'' ''0'' is set for the insiginificance. A monitoring pattern is transmitted from the subscriber station when the control data is not sent out. The monitoring pattern is inputted previsouly to a comparing circuit 20, which compares it with received data to output ''1'' or ''0''. A shift register 50 shifts the output of the comparing circuit 20 by one, two, and three clock pulses CP to send out them from outputs 1, 2, and 3. The output at a point (a) is ''1'' when the outputs 1, 2, and 3 are all ''1'' and ''0'' when not. An AND circuit 70 which inputs the output and the bit of the area 4 generates a write pulse to the control pulse when they are all ''1''. When the subscriber station is disconnected, the output at the point (a) is never ''1'' and the write pulse to the memory 30 is generated.

Title: Dot type printer
Inventor: HORITANI KEIICHI
IPC: B41J25/00
Filed: 1978-07-07
Abstract: PURPOSE:To obtain a printer which is so designed that a roller which is attached to a carrier and an eccentric cam which is in contact with the roller are so arranged that their axes become perpendicular to shifting direction of the inclined carrier so that friction between the roller and the eccentric cam become less and the carrier can move smoothly. CONSTITUTION:A shifting direction A of a carrier 2 and a centerline B of a spring 3 which is pressing the carrier 2 are parallel with each other and inclined at an angle theta. An axis C of a roller 5 attached to the carrier 2 and an axis D of an eccentric cam which is in contact with the roller 5 are perpendicular to a direction A, and as the carrier 2 receives from both sides an equilibrated force with the direction A, it can smoothly shift on a guiderail 10. Pressing direction of the roller 5 by the eccentric cam 9 also becomes the same as the direction A, and rotations of the roller 5 and the cam 9 are relatively free from sliding in up-and-down direction, and therefore, the friction can be reduced.
