Title: Radio system
Inventor: SEKI KENJI
IPC: H04W24/00
Filed: 1989-10-11
Abstract: PURPOSE:To discriminate an area not utilized by even a radio system with a difference from a transmission power automatically by extracting level information at an opposite party as to a radio wave radiation of its own equipment from a radio wave radiating from an opposite radio equipment to discriminate whether or not the both stay in the service area. CONSTITUTION:Other radio equipment 2 receives a radio wave radiating from a transmission section 14 of an opposite radio equipment 1 by an antenna 21 and the reception signal is inputted to a reception section 23 via a TR switch 22. A demodulation section 25 interprets the reception signal inputted from the reception section 23 and demodulates the electric field strength of the radio wave radiating from a transmission section 24 of the radio equipment 2 at a preceding time based on the signal. An alarm section 26 discriminates it at which degree of the electric field strength the radio wave radiating from the radio equipment 2 is received by the opposite radio equipment 1, and the alarm section 26 applies alarm display when the electric field strength is deviated at the outside of a setting range. Thus, the service area, that is, the transmission reception coverage area is confirmed by setting the electric field strength of the radio wave transmission from the radio equipment 2 into the vicinity of the sensitivity of the radio equipment.

Abstract: PROBLEM TO BE SOLVED: To attain long stabilization of a lubricating function by setting the inside diameter of an inner ring in an antifriction bearing so as to be less than a particular value, and forming an oil guiding part for guiding oil to the raceway surface of a race at the shoulder part of an outer ring. SOLUTION: A ball bearing used in a rotation supporting device is a bearing whose inner ring inside diameter is ϕ8 mm or less, namely, a small-diameter ball bearing or a miniature bearing. At a boundary part between the shoulder part 3b2 of an outer ring 3b on the stationary side or an outer ring raceway surface 3b1 and the inside diameter surface 3b3 of the outer ring 3b, an oil guiding part 32 is formed which guides oil to the outer ring raceway surface 3b1. As a result, a lubricating component adhering to the shoulder part of a race is guided to the raceway surface of the race smoothly. Therefore most of sealed lubricant can be used for lubrication of the raceway surface which is the severest lubricating condition. It is thus possible to attain long life of the rotation supporting device.

Title: Extremely low temperature device
Inventor: KANEKO TOMOMI
IPC: F25D19/00
Filed: 1994-10-28
Abstract: PURPOSE: To cool an object to be cooled only by the refrigerating machine of an extremely low temperature device by turning on a heat switch with the heat conduction of liquefied gas, and solidifying the liquefied gas and turning off the heat switch when the liquefied gas reaches its boiling point and freezing point. CONSTITUTION: When a refrigerating machine 4 begins to cool a superconductive coil 1, a heat-shield plate 8 in contact with a high-temperature side cooling stage 7 is first cooled, so that the temperature of the cylindrical member 23 of a heat switch 20 becomes low. On the other hand, the temperature of the superconductive coil 1 side in contact with a low-temperature side stage 5 remains ordinary temperature. Accordingly, heat is transferred through liquefied gas to the ordinary-temperature cylindrical member 23 of the high-temperature side cooling stage 7 from the ordinary- temperature cylindrical member 23 of the low-temperature side cooling stage 5. Then, when the gas is liquefied, the liquid drops of the liquefied gas drop on an end plate 22 depending on heat transfer due to the function of a heat pipe, and then evaporate to take latent heat from the high-temperature cylindrical member 23. As a result, the evaporating liquefied gas is liquefied again in the low-temperature cylindrical member 23.

Abstract: PROBLEM TO BE SOLVED: To enable setting of a roll revolution reflecting on rolling conditions such as the cumulative number of rolling rolls and temperature of tube stock in a stretch reducer. SOLUTION: On the entrance side of a stretch reducer 1, the actual length of a tube stock is detected by a length measuring meter 3 on the entrance side, as is the temperature of each part of the tube stock by a thermometer 5, and then, a target elongation length by the stretch reducer 1 is determined from the target length of a finished tube, so that a roll revolution is set for the stretch reducer. Meantime, on the exit side of the stretch reducer 1, the actual elongation length of the tube is detected by a length measuring meter 4 on the exit side, with the number of roll revolution corrected at each stand of the stretch reducer 1 so that the actual elongation length may coincide with the target length of the finished tube; in this case, the correction is determined by a neural network 10 based on the actual tube stock length, tube stock temperature, other dimensional items of tube stock, cumulative number of rolling rolls, target elongation length and elongation deviation.
