Title: Method for automatically calibrating ph meter
Inventor: ADACHI TORU
IPC: G01N27/26
Filed: 1992-02-06
Abstract: PURPOSE:To reduce the size of a pH standard liquid tank by minimizing the amount of usage of a pH standard liquid as needed, save space and reduce running cost, and then reduce manufacturing cost without requiring a new device for detecting change in flow rate or a determination pump. CONSTITUTION:With the time when an electromagnetic valve 11 is opened as a reference time, a pH meter reference stabilization time until pH of a pH meter 1 is stabilized after a pH standard liquid 9 flows through a normal channel 10 and a conductivity reference instruction time until the conductivity of a conductivity meter 3 changes due to the pH standard liquid 9 are obtained previously. When calibrating pH actually, the conductivity instruction time until the conductivity of the conductivity meter 3 changes from a reference time due to the pH standard meter 9 is obtained, the ratio of the conductivity instruction time to the conductivity reference instruction time is integrated into a pH meter reference stability time, thus calculating pH meter stabilization time where pH of the pH meter becomes stable. The pH standard liquid 9 is allowed to flow into the pH meter 1 by the amount of pH meter stabilization time for calibrating pH.

Title: Method of mounting anticorrosive anodic material in multitubular heat exchanger
Inventor: ICHIHARA TAKAYUKI
IPC: F28F19/00
Filed: 1986-01-31
Abstract: PURPOSE:To prevent a heat transfer pipe from being corroded by electric anticorrosive effect by disposing an anodic material between lowermost end plates of an element core to form a current flow system in end plates in the vicinity of the anodic material and the heat transfer pipe. CONSTITUTION:An anodic material having a diameter which is smaller than an interval between both end plates 6 and 17a and equal to the diameter of an opening 15 of a baffle plate 9 is penetrated through the opening 15 of the rubber-made baffle plate 9 and is moved to a connector 20. Further, a mounting bolt 21 provided with a fine screw portion 18' at its end, and a screw portion 18 at its intermediate portion, and a plane for holding an 'O' ring between said bolt 23 and a recessed portion on the plane of the connector 20 is screwed to the connector 20 by screw driving a bolt head 22, for example, and at the same time, is screwed together with the fine screw part 18' formed at the right end of the anodic material A, thereby fixing the anodic material A to the mounting bolt 21 and the connector 20 so as to form an element core 11a. Thus, since anodic materials A and B, the connector 20, the 2nd plate 6 and the heat transfer pipe 8 generate an anticorrosive current between flowpaths of cooling water of an engine, the corrosion of the heat transfer pipe 8 making contact with the lower baffle plate 9 at the lower part of the element core which has been most easily corroded, can be prevented.

Filed: 1995-02-08
Abstract: PURPOSE: To provide the transistor high frequency power amplifier by reducing a capacity and power consumption of a constant voltage circuit so as to extend the service life of a power supply battery. CONSTITUTION: The power amplifier employed by a portable communication equipment using a battery 3 as a power supply is made up of a high frequency power amplifier stage 1 comprising one transistor(TR) or over, 5, 6, 7 and up of a bias voltage setting stage 2 providing an output of a control voltage fluctuated in reverse direction to a fluctuation of an output voltage of the battery 3, a voltage of the battery 3 is fed to collectors of the TRs 6, 7 as a drive voltage and a control voltage is applied to bases of the TRs 5, 6, 7 as a bias voltage.  When the voltage of the battery 3 is higher than a rated output voltage, the bias voltage applied to the bases of the TRs 5, 6, 7 is set lower than the standard bias voltage, a signal amplification factor of the high frequency power amplifier stage 1 is suppressed and power consumption of the battery 3 is suppressed simultaneously to extend the service life of the battery 3.

Title: Recording apparatus
Inventor: SAITO YASUHIDE
IPC: B41J23/02
Filed: 1988-01-30
Abstract: PURPOSE:To obtain a correct accuracy in feeding sheets of papers, by providing a rotary member which has a first and a second transmitting units integrally formed with an output stage of a single motor, so that the driving force of said motor is transmitted to a carriage moving mechanism through the former transmitting unit, and to a feeding mechanism of an object to be recorded through the former transmitting unit. CONSTITUTION:When a carriage 5 performs shifting for recording, a stepping motor 7 is rotated in a direction A, and a worm gear 26 and a belt driving pulley 25 are also rotated. Therefore, a worm wheel 22 is rotated in a direction E. At this time, since a spring clutch 24 is not engaged with an arbor 23, a roller shaft 21 is not rotated, and accordingly a paper is not fed by a feed roller 9. The carriage 5 is moved in a direction C by the rotation of the pulley 25 in the direction A, so that recording operation is carried out. When recording is finished, the motor 7 is rotated in a reverse direction so as to return the carriage 5 in a direction D. When the worn wheel 22 is rotated in a direction F, the spring clutch 24 is engaged with the arbor 23, whereby the paper sheet is fed by the feed roller 9. Thus, the recording apparatus can be free of backlashes or rattlings.

Title: Rubber vibration isolator
Inventor: TAKAHASHI TOMOYASU
IPC: G10K11/16
Filed: 1995-01-13
Abstract: PURPOSE: To provide a rubber vibration isolator heightening sound insulating and vibration damping effect by forming a hollow part in a rubber body, and filling granules in the hollow part. CONSTITUTION: Mounting members such as a connecting base 2 and a connecting bolt 3 are added to a lump rubber body 1. A hollow part (a) is formed inside the rubber body 1, and granules 4 are filled in the hollow part (a). A rubber vibration isolator is used in the connecting place and supporting place of various equipment to be vibration generating source. When the vibration of various equipment is transmitted, this vibration is absorbed by the own elasticity of the rubber body 1, and the vibration of the rubber body 1 causes the deformation of the hollow part (a). As a result, the granules 4 in the hollow part (a) are moved, and the vibrational energy is absorbed by the movement of the granules 4, so that the vibration is damped remarkably.  The generation of sound based on vibration can therefore be suppressed so as to obtain the rubber vibration isolator excellent in sound insulating effect.

Title: Method and apparatus for measuring position of rail, and measuring apparatus for angle of attack
Inventor: YAMASHITA YUJI
IPC: G01B11/00
Filed: 1993-02-09
Abstract: PURPOSE:To measure the position of an end of a rail during running by projecting a linear light beam onto the rail face, forming an image of the scattering light on a line sensor and measuring the position by the size of signals from each pixel of the line sensor. CONSTITUTION:The laser light from a light source 9 is projected with some diverging angles, which is received by a collimator lens 10. As a result, a beam waist is generated in the vicinity of the tread of a rail 1. A cylindrical concave lens 11 is so arranged as to have its axis of the cylinder in parallel to the longitudinal direction of the rail 1, diverging the incident light in the perpendicular direction to the axis. Therefore, the light emitted from the lens 10 is diverged in the lateral direction of the rail 1 by the lens 11 and turned to slim linear beams traversing the rail 1 in the vicinity of the tread of the rail 1. The linear beam are scattered at the surface of the rail, so that a projected pattern 8 is seen from all the directions. The scattering light from the pattern 8 is detected by a photodetecting lens 12 disposed slantwise up in the longitudinal direction of the rail 1, and an image is formed on a photodetecting surface of a CCD line sensor 13.
