Title: Semiconductor integrated circuit
Inventor: TAGUCHI MASAO
IPC: H01L39/06
Filed: 1988-03-11
Abstract: PURPOSE:To keep an integrated circuit superconductive and enable signals to propagate at a high speed by a method wherein a relation between the width and the length of the gate of a FET is specified. CONSTITUTION:MOS transistors T11-T14 are used as a drive device and a superconductive wiring SCx in wiring width is used as a signal wire. An FET T1 provided with a gate width W and a gate length L is so set as to satisfy an inequality, W/L<(2JClambdaOX)/{muCOx(VG-Vth)<2>}, where VG denotes a gate voltage of the FET T1, Vth represents a threshold voltage of the FET T1, mu is an effective mobility of carriers, COX is a gate oxide film capacitance of the FET T1, JC denotes a critical current of a high temperature superconductive wiring SC, and lambdaOx is a random depth of the superconductive wiring SC. When the wiring width of a superconductive wiring is determined as mentioned above, a drive current of a drive device can be made lower than a critical current of the superconductive wiring, so that the superconductive wiring can be kept in a superconductive state and signals can be propagated at a high speed.

Filed: 1985-03-23
Abstract: PURPOSE:To obtain a magnetic recording medium which has high coercive force, a small noise level, high S/N and high corrosion resistance by forming a thin magnetic film layer of a Co-Ni-Cr alloy contg. about 3-17atom% Cr on a Cr layer of a nonmagnetic base to about 400-2,000Angstrom  thickness. CONSTITUTION:The Cr film is constituted as the underlying layer of the magnetic film consisting of the Co-Ni-Cr alloy. The alloy film in which Cr is incorporated at about 3-17atom% and which has about 400-2,000Angstrom  magnetic film thickness is used for the magnetic film consisting of the Co-Ni-Cr alloy. For example, the aluminum substrate plated with Ni-P is subjected to DC magnetron sputtering using Cr having 8-inch diameter as a target under the conditions of PAr 5milliTorr to form the Cr layer on the Ni-P plating layer at about 2,500Angstrom . The substrate formed with the Cr layer is then subjected to DC magnetron sputtering using the Co of the 8-inch diameter placed with 7X7mm Ni chip and 7X7mm Cr chip as the target under the conditions of PAr5milliTorr to form the thin magnetic film layer consisting of the Co-Ni-Cr alloy on the Cr layer. The magnetic disk is thus obtd.

IPC: F24F3/04
Filed: 1989-03-14
Abstract: PURPOSE:To provide an air conditioner requiring only a small construction space and a minimum construction cost having a highly efficient operation by a method wherein a compressed air is supplied to an air supplying passage, a turbine fan is provided in a discharging passage and the air is discharged up to a ground while sucking a discharged air in a underground space. CONSTITUTION:A high pressure air tank 3 is arranged within a high deep underground space 1 and air of which pressure is kept by a compressed air plant 2 is accumulated within a high compressed air tank 3. An air supplying passage 5 connects between a compressed air plant 2 and a high pressure air tank 3. A compressor 6 is connected to the turbine fan 4. The compressor 6 is rotated by a turbine fan 4 and the air within the high deep underground space 1 taken from the discharged port is compressed by the compressor 6 and then it is sent to the discharging passage 7 communicating with a surface ground. Accordingly, the air is sent under its compressed state, resulting in that it is possible to reduce a sectional area of the air supplying passage and at the same time it becomes possible to supply a large amount of air without providing any installation of the relay unit for use in assisting an air supplying operation in the midway of the air supplying passage.
