Title: Manufacture of oxide superconducting coil
Inventor: HOSONO FUMIKAZU
IPC: B28B1/00
Filed: 1989-03-23
Abstract: PURPOSE:To obtain an oxide superconducting coil which can provide characteristics of oxide superconducting wire material even after it is coiled by restricting the thermal expansion of a metal-coated oxide superconducting wire material with a material having smaller thermal expansion coefficient than that of the metal coating, and sintering to heat treat it. CONSTITUTION:In order to manufacture a pancakelike coil by applying a metal- coated oxide superconducting wire material, the thermal expansion of the wire material is restricted with a material having smaller thermal expansion coefficient than that of the metal-coating of the wire material, and sintered to be heat treated. For example, fine superconducting powder having a composition of Tl8Ba8Ca8Cu3OX having a critical temperature of 120K is filled in a silver tube having 6.0mm of outer diameter, diameter-reduced to be plasticized to 2.0mm, and further rolled to a silver-coated tapelike wire material having 0.1mm of thickness. This wire material is wound in 10 turns on a pipe made of MgO having 30mm of outer diameter, and a tape of 42Cu alloy is wound on the outside of the turns. In this case, an insulating tape of MgO is inserted between the 42Cu alloy and the wire material. Thereafter, it is heat treated at 845 deg.C in an oxygen atmosphere.

Title: Liquid container
Inventor: SUZUKI YOSHIHARU
IPC: B65D81/26
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To prevent a liquid in a container from flowing out when the container falls down, and at the same time, prevent a leakage to the outside due to the closing of a suction hole by coming into contact with a liquid seasoning, and a clogging from generating. SOLUTION: The internal end part 14 of a suction hole 11 on a liquid container 1, is extended lower than the internal end part 7 of a discharging port 5 on the liquid container 1. The discharging port 5 and the suction hole 11 are formed in such a manner that A area of the discharging port 5, and B area of the suction hole 11, may receive an approx. uniform liquid pressure when the liquid container 1 falls down on a horizontal surface S under a state wherein a liquid E is housed inside so that air may not pass through either one of the discharging port 5 and the suction hole 11 being closed with the liquid E and may not enter the inside of the liquid container 1.  For the suction hole 11, the passage cross sectional area at a part being closer to the internal end part 14 is made larger than that of an external end part 13, and when the container 1 is erected, the liquid in the suction hole 11 is made to stream down.

IPC: B22D18/04
Filed: 1989-03-23
Abstract: PURPOSE:To prevent the development of defective product by outputting a signal after the lapse of the prescribed time from starting supplying of molten metal into cavity and providing control means for changing the pressurizing pattern to molten metal surface with this signal. CONSTITUTION:Pressurized air is supplied into a pressurizing chamber 20 through an air supply passage 42, and the molten metal in a crucible 12 is pushed up, supplied and packed into the cavity 32 in a mold 30 to produce the casting. When the filling-up of the molten metal completes, this is detected with a filling-up detecting sensor 58 fitted at the upper part of the mold 30, and CPU 62 outputs command for changing the pressurizing pattern. Even in the case the filling-up detecting sensor 58 is not normally worked, after the lapse of the prescribed time preset to a timer 60, the signal is transmitted to the CPU 62 and the CPU 62 outputs the command for changing the pressurizing pattern. Even if the filling-up detecting sensor becomes defective, the development of the defective product can be prevented.

Title: Fuel cut control device of internal combustion engine
Inventor: KAWAI TAKASHI
IPC: F01N3/20

Abstract: PROBLEM TO BE SOLVED: To prevent the torque shock accompanying the transfer from fuel cut prohibiting state to fuel cut executing state by prohibiting the transfer from fuel cut prohibiting state by a fuel cut prohibiting means according to the temperature reduction of a catalyst to the fuel cut executing state by a fuel cut executing means. SOLUTION: In the traveling of a vehicle, it is judged whether an idle-on F/C(fuel cut) condition or a slope descending F/C condition is established or not as deceleration fuel cut condition in an ECU 90, and when the judgment result is YES, it is judged whether the catalyst temperature rise corresponding quantity is larger than a judgment standard value or not. When this judgment is NO, transfer to F/C executing state is performed. However, when F/C prohibiting state was once set, the F/C prohibiting state is kept. Namely, it is judged whether a F/C prohibiting control flag is 1 or not, and when the flag is 1, or the F/C prohibiting control is under execution, the F/C execution control flag is set to 0 in order to continue the F/C prohibiting state to make the F/C non-executing state.

Abstract: PURPOSE:To prevent an amplifier as a rear stage from being overloaded and to improve transmission quality by sending out the output of a fixed gain means as the output of the automatic gain control circuit only for a specific time after an abrupt level rise of a pilot signal is detected. CONSTITUTION:A received signal and the pilot signal are inputted to an input terminal 1, amplified by an amplifier 2, and supplied to a level adjusting circuit which has resistances R3 and R6 and a thermistor 5. The pilot signal is extracted by a BPF7 and supplied as the heater current of the thermistor 5 through an amplifier 8, rectifier 9, and DC amplifier 10. The comparator 8 detects an abrupt level rise of the pilot signal to operate a time limit circuit 14 and also energize a relay 12, thereby switching a contact 13 to the side of a fixed resistance 4. Further, the contact 13 is returned by the circuit 14 to the side of the thermistor 5 after the resistance becomes stable. Thus, the amplifier as the rear stage is prevented from being overloaded and the transmission quality is improved.

Filed: 1985-04-08
Abstract: PURPOSE:To make tracking quickly by shifting a reproducing head to the center of two head positions where an envelope takes threshold value for a track. CONSTITUTION:When an envelope 110 of a signal recorded in a track of a magnetic disk is detected by an envelope detecting circuit, head positions X1 and X2 of two points 112 and 114 at which the envelope 110 cuts a specified reference value, i.e. a threshold value Vth are found, and the position of simple average of the two head positions X1 and X2, i.e. the center position X of the two is regarded as the center of the track, and the head is shifted to this position. Accordingly, if the envelope 110 is in ideal condition and signals are recorded in the disk, the position of its peak 116 nearly coincides with the position X. In this case, when the position of the reproducing head is in a track of larger diameter out of plural tracks, the reference value is made higher than the case where the position is in a track of smaller diameter.

Title: Catalyst for polymerization of olefin
Inventor: HIRUTSUKA KUNUUTEIRA
IPC: C08F4/24
Filed: 1991-01-16
Abstract: The present invention concerns a catalyst for polymerization of olefins, said catalyst comprising an inorganic support material with catalytically active chromium and titanium compounds bound on its surface. The catalyst is prepared according to the invention by bringing the catalytically active metal compounds sequentially in vapour phase onto the support material surface in excess amounts in relation to the binding sites available on the support material surface. The support material temperature is maintained above the condensation temperature of the vapour, preferably above 160 DEG C, and simultaneously sufficiently high so as to achieve the thermal activation energy necessary for the generation of bonds between the support material and the catalytically active material or its compound. To avoid desorption of the chemisorbed compounds, the temperature is kept below approx. 500 DEG C. The activity of a catalyst in accordance with the invention even with very low contents of the catalytic metals is as high as the activity of a catalyst of multiply higher metal contents that has been prepared by the methods of the conventional technology.
