Title: Recording device and recording sheet
Inventor: IWATA MASAKATSU
IPC: B65H37/04
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To beautifully finish a work without being troublesome by controlling to carry so as to overlap the extreme end of a succeeding recording sheet with the rear end of a recording sheet, in the case of long record. SOLUTION: In this device, the carrying speed of a feed roller 6 is faster than the carrying speed of a carrying roller 10, and even if feed of next recording sheet is begun since the rear end of a recording sheet is detected, the preceeding recording sheet can be overtaken on the way. Consequently, since the rear end of the recording sheet is detected by a sheet sensor S1, feed of the next recording sheet is begun so as to obtain a fixed overlapping quantity considering the carry of the feed roller 6. The next recording sheet is controlled so that a remaining quantity G on the upper stream side from between the carrying roller 10 and the pinch roller 11 becomes a fixed overlapping quantity. By overlapping the next recording sheet with the recording sheet during recording in this way, printing is continued without complicated control, and banner (long) record can be easily performed.

Title: Method for preventing intergranular stress corrosion cracking of ni-based alloy
Inventor: MINAMI TAKAO
IPC: C23F11/06
Filed: 1986-11-20
Abstract: PURPOSE:To effectively prevent the intergranular stress corrosion cracking of the Ni-based alloy which is brought into contact with a deaerated alkaline soln. at high temp. by adding a specified amt. of a cyclic amine to the deaerated alkaline soln. CONSTITUTION:From 0.3ppm to 1%, based on the weight of a soln., cyclic amine such as morpholine, cyclohexylamine, and piperazine is added to the deaerated alkaline soln. to be used in a heat exchanger, etc., and exposed to a high temp. An increase in the corrosion potential of an Ni-based alloy due to the impurities such as Fe3O4, Cu, Cu2O, and CuO which are eluted into the soln. in the form of sludge or scales and deposited in the high-temp. deaerated alkaline soln. is controlled by the cyclic amine. Furthermore, the entrance of the potential into the corrosion cracking generating potential region is also prevented. As a result, even when a member consisting of an Ni-based alloy is incorporated into an existing plant, the corrosion cracking of the member can be prevented without disassembling the plant.

Title: Multiple inverter device and control method therefor
Inventor: ICHIKAWA KOSAKU
IPC: H02M7/48
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To reduce the size and output high voltage without the need for output transformer, and reduce higher harmonics to the load side by connecting the unit inverter cell in each phase with an input transformer having multiple winding on the secondary side out of phase. SOLUTION: A secondary winding 3S of an input transformer 3 comprises three sets of windings constituted in 18 phases, shifted from one another by an electrical angle of 20 degrees, and an individual unit of them is connected with the same stage of unit inverters constituting the respective phases. Even if an n-th stage in each phase is bypassed, the harmonic components in input current become identical without disturbing the 18-phase constitution. The input transformer 3 having the plurality of the secondary winding 3S and the unit inverter cells 4U1-4U3, 4V1-4V3, 4W1-4W3 are combined with each other. As a result of this, the size can be reduced and high-voltage output can be obtained, without the need for output transformer. Since it is unnecessary to select semiconductor devices constituted in series, gate control is simplified.  Since the circuit voltage is reduced, the reliability of the device is enhanced. The output- side harmonic component can be determined at a PWM switching frequency of the semiconductor devices.
