Abstract: PURPOSE:To enable the operation of each zone to proceed in parallel by dividing the unit operation of vacuum impregnating operation into zones corresponding to the number of centrifugal separators to proceed the impregnating operation by a zone in response to the rotation of the centrifugal separator. CONSTITUTION:After an article 8 to be impregnated is received from a conveyer 16 into a first zone I to be fixed to a centrifugal gauge 6 of a centrifugal separator 1A, a vertical type pivot 2 is pivoted. When the article advances to a second zone II, the impregnating operation begins. When a vacuum pump 15 is operated and an impregnating liquid tank 11is evacuated, the interior of a next in said article 8 is also evacuated. And said tank 11 is released from the vacuum after a certain time. After the impregnating liquid is forced into the interior of next, a pivot 2 is pivoted to advance said article to a third zone II. Here, after superfluous impregnating liquid is shaken off by a centrifugal separator 1C, said impregnated article 8 is advanced to a fourth zone IV to be rinsed. Further, a centrifugal separator 1E is rotated in a fifth zone V to shape off attached washing water and complete the impregnating operation.

Patent JP-H08330570-A (JP)
Title: Composite semiconductor device and power conversion device using the same
Inventor: SAKANO JUNICHI
IPC: H01L29/749
Filed: 1995-06-01
Abstract: PURPOSE: To reduce resistance loss and enlarge the safe operation region, by making the breakdown voltage between the source and the drain of a p channel MISFET lower than the breakdown voltage between the source and the drain of an N channel MISFET. CONSTITUTION: A region where the interval between a p1 layer 14 and a p2 layer 15 is large (L) and a region where the interval is small (LS) exist in a semiconductor device. The voltage between the source and the drain of a P channel MISFET (M3) is determined by a voltage wherein an (n-1) layer 1 in the part of LS is turned into a depletion layer and punch through is generated. By reducing LS, the breakdown voltage between the source and the drain of M3 is made lower than or equal to the breakdown voltage between the source and the drain of an N channel MISFET (M2). Thereby an excessive voltage is not applied to M2, and a wide safe operation region can be obtained. Since the region of L is formed, electron injection into the (n-1) layer is not damaged. As the result, the wide safe operation region can be maintained while easy-ON and low resistance loss are maintained.

Title: Manual operation reader
Inventor: TAKADA YUJI
IPC: G06T1/00
Filed: 1988-06-01
Abstract: PURPOSE:To surely read only a required position without special attention to a stop position of paper face scanning by bringing the mode to the read length designation mode prior to the read of a picture on paper face and scanning the position required for reading. CONSTITUTION:A mode setting switch 20 is turned on to scan the position required for reading in advance. Since a pulse signal in response to the moving distance is generated from an encoder 2 attended with the scanning of paper face, after a CPU 22 initializes a count P, the count of the pulse signal is continued. If no pulse signal is inputted within a prescribed time, the CPU 22 discriminates it that the paper face is scanned and stopped for the position required for reading by a distance L0 and stores the count P counted so far as the read length designation value in a RAM 24. Thus, the required length L0 only is read surely without any special attention to the stop position of the paper face scanning.

Title: Cable way protection element
Inventor: TSUJI MASAYUKI
IPC: F03G7/06
Filed: 1989-05-29
Abstract: PURPOSE:To restrain the change of characteristics due to the repetition of operation by specifying the material of a shape memory alloy and realizing orthorhombic phase transformation in the device wherein a circuit breaker mechanism operates with the shape change of the shape memory alloy upon the supply of overcurrent to a heater coil. CONSTITUTION:When overcurrent flows to a heater coil 9, heat generated thereby causes a rise in the temperature of a shape memory alloy spring 8. When the temperature exceeds a phase transformation start temperature level, the shape memory alloy spring 8 suddenly tends to be deformed in such a way as to push up a plunger 7. The concerned spring 8 is in a restrained condition and, therefore, when a load exceeds a sum of loads generated from the constant load bias application spring 12 of a load lever 6, the latch mechanism of a circuit breaker connected to the load lever 6 is unlocked and a circuit is thereby broken. In this case, the shape memory alloy spring 8 is made of nickel-titanium- copper metal and the phase transformation mechanism thereof related to a shape change is so made as to give orthorhombic phase transformation.

Abstract: PROBLEM TO BE SOLVED: To overlap-scan with an excess overlapping part reduced as far as possible, by setting two different shift amounts from a scanning position to the next based on the number of multiple array detectors and the overlapping width and alternately repeating the shifts. SOLUTION: Overlap scanning is carried out alternately using first and second shift amounts to a three array X-ray detector with the array number of three. The shift amount from SCAN #1 to SCAN #2 equals to TH/2 where TH is the slice thickness. The shift amount from SCAN #2 to SCAN #3 equals to 5.TH/2. After that, the first shift amount and the second shift amount are alternately repeated. By setting the shift amount in such a manner, scanning completely without an excess over lapping part can be carried out.
