Title: Oil pressure regulator for step feed device
Inventor: SUGINO KENJI
IPC: B23B47/18
Filed: 1980-03-31
Abstract: PURPOSE:To stabilize the velocity of cutting feed in a low speed range and prevent abrupt load at the time of resumption of cutting, by improving the throttle valve of an oil pressure regulator which controls the feed velocity of a step feed device and by providing an oil passage with a differential valve. CONSTITUTION:When a drill is moved forward under quick feed, a travel adjusting screw integrated with the drill comes into contact with the rear end face of a piston rod 17 so that pressurized oil in a pressurized oil chamber 41 is conducted into a differential valve G through a passage 14, a V-groove 5 and passages 27, 28. A groove is provided on the peripheral part of a rotary valve 3 so that the depth of the groove varies gradually. The groove cooperates with the inside surface of a cap 6 to constitute a throttle valve between the passage 14 and the V-groove 5 to set the drill at a cutting feed speed. The oil conducted into the differential valve G pushes a valve 36 to connect passage 30, 33 to each other and flows into a pressurized oil chamber 42 to retract a piston 22. When the drill is quickly moved back, the valve 36 is returned to retract the piston rod 17 for a distance corresponding to the displacement due to being pushed by the valve 36.

Abstract: PURPOSE:To control an ultrasonic motor properly according to the character of load torque by correcting the value of a target signal based on a state signal to be obtained through comparison between an input signal and an output signal from a piezoelectric element for detecting the driving state. CONSTITUTION:When a material grip command, e.g. a target position signal or a power signal, is fed from a manipulator system 4 to a gripper system 5, a gripper controller 5 rotates an ultrasonic motor 7 then the rotation is transmitted to grippers 81, 82.

Title: Neutron measuring pipe handler
Inventor: SAKAMAKI KAZUO
IPC: G21C19/20
Filed: 1988-02-25
Abstract: PURPOSE:To surely and easily check, from above a nuclear reactor, that the spindle of the front end pipe of a neutron measuring pipe is brought to a drawable position by putting on a lamp when the above-mentioned spindle is pushed down to the position where said spindle is disengaged from the recess on the rear face of an upper grid plate. CONSTITUTION:A piston rod 45 is driven to a projecting direction by the pressurizing force on a cylinder 40 by which a gripping member 64 is advanced and is fitted to the spindle 3. The gripping member 64, thereupon, fits to a collar part 3a of the spindle 3 when a neutron measuring pipe handler 10 is lowered by gravity. The spindle 3 is disengaged from the recess 6 on the rear face of the upper grid plate 5 when said device is further lowered by gravity. A limit switch 15 comes into contact with the upper grid plate 5 and turns on to put on the light 70 at this time. An operator knows that the spindle 3 is disengaged from the recess 6 of the upper grid plate 5 upon lighting of the lamp 15 and, therefore, the operator pulls back the gripping member 64 as the next step. The neutron measuring pipe 1 is thereby withdrawn into the whole of a fixing base 62.

Abstract: PURPOSE:To increase the translation success rate and translation speed by making a feedback display of information on the correct/incorrect status, absence, and vagueness of a syntax analysis in real time in parallel to the input of an original document. CONSTITUTION:A syntax analyzing means 2 reads an input sentence automatically and uses information of a grammar information knowledge base 3 to analyze the structure of the sentence. A decision means 5 uses the grammar information and information of a translating function knowledge base 4 to decide whether or not the analytic result obtained by the syntax analyzing means 2 is correct as to syntax and meaning and whether or not the input sentence meets the requirements of a failure in translation by the translation assisting device. The decision results are sent as decision result codes to a feedback means 6, which converts the decision result codes into output messages and outputs them on the display of an original document generating means 1. An operator uses an original document input means 1 to correct the input sentence according to the indications of the messages. Consequently, the translation success rate and translation speed can be increased.
