Title: Chamfering device for pipe end surface
Inventor: KITAOKA TAKEO
IPC: B23B5/16
Filed: 1983-12-29
Abstract: PURPOSE:To easily chamfer an end surface of a pipe with high quality by making use of a little power whatever the size of a workpiece pipe is. CONSTITUTION:For deformation of the outer diameter of a pipe in processing, the spool 74 in a servo valve 45 is moved via a guide roll 71 in contact with a pipe outer peripheral surface and a roll support lever 72, whereby a flow rate of pressure oil to a hydraulic cylinder 32 is adjusted. The hydraulic cylinder 32 is operated by the amount of the pressure oil, and thereby a first slide bench 30A is moved. A cutting tool 62 is rotated at all times around a pipe shaft following the unevenness of the pipe surface. Accordingly, even if the pipe outer peripheral surface is deformed, the depth of bite of the cutting tool 62 is uniform, enabling high precision chamfering to be effected.

Title: Mode-checking mechanism and mode-adjusting mechanism for laser beam
Inventor: OKADA KAZUAKI
IPC: H01S3/098
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To automate mode adjustment of a laser beam from a laser oscillator. SOLUTION: The inclination of a total reflection mirror of a laser oscillator having a condenser 13 is adjusted by an adjusting mechanism section 15, including piezoelectric elements 5, 6. A laser beam 14, outputted from an emission mirror 10, passes through a hole provided at the center of a mode detecting section 11, where the mode of the laser beam is detected. In the mode-detecting section 11, four thermosensitive elements separately provided around the center hole output signals, when the temperature rises. A voltage is applied to the piezoelectric elements 5, 6 in response to the signals, so as to adjust the inclination of the total reflection mirror 3, thus causing the cross section of the laser beam to be a true circle.

Title: Vibration control device
Inventor: MUTAGUCHI KATSUO
IPC: E04H9/02
Filed: 1992-08-24
Abstract: PURPOSE:To simplify the structure and lighten the weight by forming the movable element of a linear motor, provided with the movable element and a stator, into a vibration damping body, and fixing the stator onto the structure side. CONSTITUTION:The stator 5 of a linear motor 6 formed of a movable element 4 and the stator 5 is disposed between guide rails 2, parallel with the guide rails 2 with a specified clearance to the movable element 4. An exciting power source is connected to the stator 5, and a variable driving power source is connected to the movable element 4. When a current is applied to the movable element 4 with a primary iron core, dielectric electromotive force is generated between the stator 5 with a secondary iron core and the movable element 4, so that the movable element 4 travels on the guide rails 2. When the movable element 4 is made travel in the reverse direction to external force acting upon a structure 1 at the time of oscillation being generated to the structure 1, the movable element 4 functions as a vibration damping body, and the oscillation of the structure 1 can be suppressed rapidly. Since the movable element 4 is provided with the function of the vibration damping body, the rectilinear motion of the vibration damping body can be easily obtained with simple structure.

Title: Active common-mode canceler
Inventor: OGASAWARA SATOSHI
IPC: H02M1/12
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To remove a trouble in a common-mode voltage caused by a step- shaped change by a method wherein a voltage whose magnitude is identical to that of the common-mode voltage generated in the switching operation of a semiconductor element at a power converter and whose polarity is opposite is superposed on the output of the power converter so as to offset the common- mode voltage. SOLUTION: Whenever an inverter 4 is switched, the output zero-phase voltage, i.e., the common-mode voltage, of the inverter 4 is changed stepwise. Thereby, a common-mode current i(t) flows to a grounding conductor through the stray capacitance between the winding of a motor 6 and a frame. At this time, the common-mode voltage of the inverter 4 is detected by a star-connected capacitor 8, a voltage whose magnitude is identical to that of the common-mode voltage and whose direction is opposite is output to a common-mode transformer 11 which is connected in series, and the common-mode voltage can be offset completely. As a result, the common-mode current i(t) does not flow. Thereby, the common-mode voltage and the common-mode current are removed.

Abstract: PROBLEM TO BE SOLVED: To provide a method of processing pyrolysis gas for preventing the gas from being exhausted externally as it is by safely treating the gas exhausted even after emergency interruption without causing combustion. SOLUTION: Pyrolysis gas 31 having a temperature of about 450 deg.C from a thermal decomposition reactor 30 is introduced into a separation tank 33 through which cooling water 32 is circulated, and impurities such as tar and smoke dust are dissolved into the cooling water 32 for removal thereof, and further exhaust gas 34 cooled to 100 deg.C or lower through the cooling water is then deodorized through an activated coal tank 35 and is exhausted from an exhaust hole 39 with the aid of an air suction fan 37.

Further, even when a combustion/melting furnace, etc., are urgently interrupted, such an emergency power supply may be used that can drive a suction fan.  Moreover, there may be eliminated the need of an auxiliary fuel and a complicated combustion apparatus for burning raw gas, and the raw gas is safely and securely treated with a simplified structure.
