Title: Electrophotographic copying machine with automatic paper selecting function
Inventor: ITO MASAZUMI
IPC: G03B27/34
Filed: 1986-10-16
Abstract: PURPOSE:To prevent interruption of the copying operation due to the paper empty state by supplying sheets of paper from another paper supply hole if adapted sheets of paper are set in this paper supply hole when sheets of paper in a paper supply hole selected at present are empty on the way of the copying operation. CONSTITUTION:In sheets of paper in a first paper supply hole of an automatic paper supply cassette 20 are empty on the way of copying, it is discriminated whether the size of sheets of paper in a second paper supply hole of an automatic paper supply cassette 21 coincides with an obtained adapted size or not. If it is discriminated that this size does not coincide with the adapted size, a paper empty indicator is turned on to stop copying. If it is discriminated that the size of sheets of paper in the second paper supply hole coincides with the adapted size, the second paper supply hole is selected and a copy start flag is set to '1' to continue the copying operation. Since sheets of paper are supplied from the second paper supply hole though sheets of paper in the first paper supply hole are empty, interruption of the copying operation due to the paper empty state is eliminated.

Title: Device for detecting rate of solidification of cold heat medium
Inventor: YAMANAKA RYOSUKE
IPC: G01N25/14
Filed: 1993-10-01
Abstract: PURPOSE:To improve the accuracy in detection of a rate of solidification by detecting the temperature of a cold heat medium of which a difference between the start temperature of solidification and the completion temperature thereof is large and by calculating the rate of solidification on the basis of the detected temperature. CONSTITUTION:When the evaporation temperature of a refrigerant in a heat exchanger 16 is set lower than the temperature of a cold heat medium 14 at the time of completion of solidification thereof and cooling is started, the material 14 starts to be solidified around the heat exchanger 16 several minutes later. At this time, an evaporator outlet 20 turns to be at a lower temperature due to a difference in an internal pressure of the exchanger 16 and the material 14 is solidified first on the outlet 20 side. The solidification proceeds gradually toward the evaporator inlet 19 side. On the occasion, a temperature detecting means 11 is provided at a position at which the material 14 is not solidified and maintained in a state of liquid even when a rate of solidification at which the cooling is to be stopped is reached, that is, at a position located on the somewhat lower side of the center in the depth direction in the vicinity of the end part on one side of a cold storage tank 15, and a temperature detected thereby is outputted to a solidification rate computing means. The solidification rate computing means computes the rate of solidification on the basis of the detected temperature with reference to a data table and outputs it.

Abstract: PURPOSE:To improve S/N by incorporating magnetic Co-gamma-Fe2O3 powder specified in SBET specific surface area, coercive force and residual magnetic flux density into a 1st magnetic layer and 2nd magnetic layer and forming the 1st magnetic layer to the thickness larger than the thickness of the 2nd magnetic layer. CONSTITUTION:The magnetic Co-gamma-Fe2O3 powder having >=40m<2>/g SBET specific surface area, 600-750Oe coercive force and >=1,650 gauss residual magnetic flux density is incorporated into the 2nd magnetic layer. The magnetic Co-gamma-Fe2O3 powder having 26-40m<2>/g SBET surface area, the coercive force equal to or lower than the coercive force of the magnetic powder incorporated into the 2nd magnetic layer and >=1,800 gauss residual magnetic flux density is incorporated into the 1st magnetic layer. The 1st magnetic layer is formed to the thickness larger than the thickness of the 2nd magnetic layer. Since advantage is taken of the feasibility of lowering the noise level possessed by the magnetic powder of the fine particles having the large specific surface areas in the above-mentioned manner, the effect of improving a transfer characteristic by the 1st magnetic layer and the effect of lowering the noise level by the 2nd magnetic layer are interacted with good balance to lower the noise level and to improve S/N.

Title: Water rod
Inventor: KASHIWAI SHINICHI
IPC: G21C3/322
Filed: 1990-09-19
Abstract: PURPOSE:To obtain a water rod which is free from a sudden rise of a liquid level inside when a pressure of a reactor core rises sharply by providing a suppression chamber near an output of a down pipe of the water rod to store water reversed. CONSTITUTION:A suppression chamber (SC) 11 has a sectional area larger than that of a lower passage 5 and is disposed below the passage 5. A discharge pipe 12 is arranged from the SC11 outside a rising pipe 2. When a pressure change occurs, water enters a water rod 1 by a portion corresponding to the compression of steam in the water rod 1 from an inlet 8 and an outlet 9. The water revered from the outlet 9 passes through the discharge pipe 12, enters the SC11 to fill and then enters the passage 5. As the sectional area of the SC11 is larger than that of the passage 5, the water rod 1 provides a slow and small rise in liquid level of the passage as compared with the water rod without the SC11.

Title: Segment type bearing device and vertical shaft drainage pump
Inventor: AIZAWA KOJI
IPC: F16C17/04
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To perform a stable operation for a long time even when rainwater (pumped liquid) is carried into a bearing device by using a liquid nonvolatile and having a specific gravity larger than the pumped liquid as lubricant. SOLUTION: This device has a plurality of segment-like guide bearings 5 arranged along the circumference between a bearing case 4 and a sleeve 2 and an oil tank 6 for storing its lubricant 7. As the lubricant 7, a nonvolatile liquid having a specific gravity larger than a pumped liquid (rainwater), for example, a fluorine oil (specific gravity: about 2.0) or a phosphate oil (1.2) is preferably used. Since the lubricant 7 has the specific gravity larger than that of the pumped liquid even if the pumped liquid is penetrated into the bearing device, the pumped liquid layer is formed above the lubricant 7 in the oil tank 6.  Therefore, the bearing 5 is continuously operable for a long time since it is laid in the state dipped in the lubricant 7, and the lubricant 7 is not carried out of the device since it is not substituted by the pumped liquid, so that the contamination can be also prevented.

Title: Electromagnetic flowmeter for fast excitation
Inventor: MITSUTAKE ICHIRO
IPC: G01F1/58
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To enable a high excitation frequency to be used with a simple modification by providing an excitation part for each excitation coil and supplying an AC excitation current in synchronization with a total excitation coil from an excitation part corresponding to each excitation coil. SOLUTION: Excitation parts 2 and 3 of a converter l are circuit parts for supplying an AC excitation current to excitation coils 12 and 13, respectively, and synchronize AC excitation currents being supplied to the excitation coils 12 and 13 each other based on a signal from a synchronization control part 4. Since the excitation parts 2 and 3 are provided for each of the excitation coils 12 and 13, an inductance L at the excitation coil side viewed from the excitation part becomes the half even if the number of turns of each excitation coil is the same as compared with a case when two excitation coils being connected in series are driven by one excitation part as before. Therefore, even if an excitation frequency is increased, a region where a magnetic flux density required for sampling a detection signal being obtained from a fluid is stable can be secured.
