Abstract: PURPOSE:To measure the thickness of copper films non-destructively and continuously  in a short time by inserting insertion type eddy current measuring elements of a diameter smaller by a prescribed size than the inside diameter of a clad pipe for nuclear fuel  and sweeping the measuring elements along the inside surface of the pipe while applying test frequencies in a prescribed range thereupon. CONSTITUTION:Two pieces of eddy current measuring elements 5 are inserted into a  clad pipe for nuclear fuel of 12.5mm. outside diameter, 10.8mm. inside diameter and 4m  length having no copper films on the inside surface, and the output terminals thereof  are connected to the bridge circuit of an eddy current measuring device 1 so that the  equil. thereof is taken. A clad pipe 2 for nuclear fuel provided with a copper film of  1-10mu thickness on the inside surface is fixed to a stand 3 by means of fixing jigs 4.  One of the eddy current measuring elements in the clad pipe having no copper film is  drawn out and is inserted into the pipe 2 having the copper film. Air pressure is applied thereto from a compressor 6 with a dryer 7 to feed the element up to the position of a  stopper plate 8. This element 5 is drawn out by a sweeping device 9 at a prescribed speed until it comes to the position of a beam switch 10, whereby the pipe 2 is swept  and the results are recorded with a recorder 11.

IPC: B23C3/00
Filed: 1987-01-12
Abstract: PURPOSE:To omit hand work and to promote the reduction of cutting time, by using a roll-shaped cutting tool and forming a desired right angular part providing an uncut part to be left further moving the cutting tool to remove the uncut part. CONSTITUTION:A printed wiring board 1 is cut by moving a roll-shaped cutting tool 3 along two sides 2 which form a location for a right angular part to be formed. Here the board 1 provides an uncut part 5, surrounded by a curved surface 4 corresponding to 1/4 circumference of the cutting tool 3, to be left in a crossing part of both the sides. Next the uncut part 5 is cut by moving the cutting tool 3 to the inside along the side in the horizontal direction or to the bottom along the side in the vertical direction and or diagonally to the inside. In any of the cases, the printed wiring board 1 removes the uncut part 5 while forms an excessively cut part 7 between a curved surface 6, corresponding to the circumference of the cutting tool 3, and the sides 2. This cutting method, in which cutting work by hand can be omitted, enables the time to be reduced for cutting.

IPC: F02F3/00
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a piston for an engine by which impact noise at the time of collision against a cylinder due to its swinging movement caused by explosive combustion in the engine can be lowered. SOLUTION: The direction of force FP generated by expansion pressure P due to explosive combustion is shifted to an anti-thrust side 1a from the direction of reciprocating movement of a piston by forming a tilting angle θin a pressure receiving top land face 11 of a piston 2. Consequently, the swinging moment Mf in the counterclockwise direction affecting the piston 2 near an upper dead point immediate after explosive combustion and the suppressing moment MP in the clockwise direction by the force FP generated by expansion pressure P due to explosive combustion are well balanced.  As a result, a phenomenon that the piston 2 which contacts the anti-thrust side 1a of a cylinder during compressing process swings to the thrust side 1b immediate after explosive combustion is suppressed and the impact noise generated by collision of the piston 2 against the thrust side 1b can be lowered.

Inventor: MORIMOTO SHOZO
IPC: G02B6/02
Filed: 1989-01-13
Abstract: PURPOSE:To efficiently transmit IR energy at a low loss by providing a cooling means which cools a light transmission path with media for cooling bodies. CONSTITUTION:The cable is constituted by inserting optical fibers 1 into tubes 3, 5 and interposing the cooling media 4, 6 in the tubes. The cooling media are conceivably a cooled liquid, liquefied gas, cooled gas, etc. A liquefied gas, low-temp. liquid tank of an electronic cooling system, etc., are usable as the method for cooling the cooling media.

Title: Field-weakening control system
Inventor: KURIYAMA SHIGERU
IPC: H02P7/28
Filed: 1979-01-22
Abstract: PURPOSE: To eliminate the rapid fluctuation of speed of the electric car and to be comfortable for passengers by a method wherein when the current of the specified value or less is detected during the detection of the motor current, then, the field- weakening control is actuated after elapsing an appropriate time lag.  
     CONSTITUTION: The current passing through the motor 5 is detected by the shunt 7 and is transferred to the trigger circuit 16 through the magnetic phase shifter 15. The trigger circuit 16 emits the control signal to the chopper 8. When the making command signal T is transmitted to the making circuit 22 of the by-pass contactor BPC, then, the condenser C1 is charged through the resistor 6 and the output voltage of OPAMP1 drops, then, it makes the output signal U from the accel 13 low potential and uses magnetic phase shifter 15 as the current detection use. When the output voltage of OPAMP1 becomes small and the output of OPAMP2 becomes great, then, the output voltage of OPAMP3 becomes great after the charging time of the condenser C3, and the transistor TR4 is augmented through the resistor R25 and the diode D1O, thus, supplying power to the coil 23 to close the field-weakening contactor FWC.

Abstract: PURPOSE:To reduce the storage capacity, by using one code as a syllable of high frequency such as ''tion'', ''ing'', or the like in words stored in an electronic dictionary. CONSTITUTION:A word is stored in an ROM in the standardized state. One data of the ROM consists of 8 bits, and upper-case and lower-case alphabets, numbers, phonetic symbolts, Katakana (square forms of Japanese syllabary), special symbols, etc. are stored in the ROM. The spelling of the word is stored in an area 1 of the ROM, and its part of speech, modified forms, idioms, etc. are stored in an area 2 and following areas. When a syllable of a high frequency such as ''tion'', ''ing'', or the like is inputted in the word to be stored in the area 1, a symbol consisting of one specific code is used. Thus, the storage capacity of the ROM is reduced, and the operation is simplified.
