Patent JP-H0377207-A (JP)
Title: Superconductor
Inventor: TSUCHIDATE HIROYUKI
IPC: H01B12/16
Filed: 1989-08-17
Abstract: PURPOSE:To obtain a kind of superconductor having a small amount of generation of Joule heat and high superconductive stability by forming the superconductor through the process of coating the surface of each of superconductive element-wires with an aluminium material. CONSTITUTION:A superconductor 11 is of a forced cooling type, and each of twisted- wire conductors 12 composing the superconductor 11 is formed by giving 3X3X3 intertwists sequentially to primary twisted-wires 13 in process of making each unit composed of the number of the wires increased in geometric propression and then intertwisting the seven resultant unit. Each of the primary twisted-wires 13 is composed by intertwisting three superconductive element-wires 14 each having stabilized copper. Each of the copper-stabilized superconductive element-wires 14 has its surface coated with a stabilizing aluminium material 14a whose surface is covered with an aluminium- anodized coat 14b serving as an insulating coat by anodizing the aluminium surface. Since the aluminium material 14a is small in electric resistance a comparated to copper while being also low in the rate of rise in electric resistance within a magnetic field over the copper, it has a small amount of generation of Joule heat and therefore is desirable for use of a superconductivity stabilizing material for a superconductive wire while mutual coupling losses of the superconductive element-wires 14 are prevented by anodizing the aluminium surfaces thereof.

Title: Electronic small-sized refrigerator
Inventor: SUZUKI NOBUAKI
IPC: F25D11/00
Filed: 1989-08-18
Abstract: PURPOSE:To identify article to be cooled such as cooled refreshing drink in a refrigerator without opening the cover of a case by composing all or part of a vessel support for forming vessel containing chambers and a refrigerator case of a transparent or translucent material. CONSTITUTION:A vessel support 6 for forming vessel containing chambers 9 - 13 is formed of a transparent material, and the front side of a case 23 is further formed of a transparent material 23a so that vessels 14 - 18 in a refrigerator can be visually observed from the front face side out of the refrigerator. When the cover 23 is formed of similar transparent material at the case cover 7 covering the case 23, the heads of the vessels 14 - 18 can be visually observed from above the refrigerator 1.

Title: Dynamic quantity sensor and displacement measuring apparatus using this dynamic quantity sensor, displacement measuring method, apparatus and method for vibration control
Inventor: YAMAMOTO SHIZUO
IPC: G01C19/00
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To directly detect the time differentiation of acceleration, i.e., jerk. SOLUTION: If an acceleration (a) acts on a base portion 3, a cantilever body 4 is curved, and an angular velocity Ω is generated at its tip part. The angular velocity Ω is detected by a vibrating gyro 5. If the acceleration (a) is constant, the cantilever body 4 becomes at a standstill at a certain quantity of deflection. Since any angular velocity Ω is not generated at the tip part of the cantilever body 4, on this occasion, the output of the vibrating gyro 5 becomes zero. Until the acceleration (a) changes in point of time, the cantilever body 4 does not curve, and any angular velocity Ω is not generated at the tip part, and the vibrating gyro 5 does not generate an output. Namely, the vibrating gyro 5 outputs a signal according to the time differentiation of the acceleration (a), i.e., jerk.

Title: Semiconductor memory and fabrication thereof
Inventor: OKUDAIRA TOMONORI
IPC: H01B3/12
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To implement a semiconductor memory including a capacitor having a larger capacitance than that of a prior art with the same occupation area, by forming a lower electrode made up of an electrode layer and a first side wall of metallic material. SOLUTION: An interlayer insulating film 6 is formed on an upper surface of a semiconductor substrate 1 made up of a separating/insulating film 2 and a gate electrode 5, a contact hole 7 is made in the surface of the substrate 1, a doped polysilicon film is embedded in the hole to form a plug 8, and then an electrode pattern 11 made up of a barrier layer 9 and an electrode layer 10 is formed on an upper face of the plug. Formed on a side wall of the electrode pattern is a side wall 15 of a Pt film so that the electrode layer 10 and Pt-made side wall 15 form a lower electrode. Thus a contact area between the lower electrode and a dielectric film is increased to (S1+S2) (S1: prior art contact surface), i.e., increased by S2.  The contact area between the lower electrode and dielectric film can be made large and thus a capacitor can be increased in capacitance while avoiding increase in a planar occupation area of the capacitor.

Title: Plasma cvd equipment
Inventor: MATSUDA AKIHISA
IPC: H01L21/20
Filed: 1984-10-09
Abstract: PURPOSE:To obtain a uniform film by providing a shutter between opposing anode and cathode electrodes so that a film is not formed until electric discharge is stabilized. CONSTITUTION:In order to produce a hydrogenated amorphous silicon film, a substrate is previously disposed on an anode electrode 2 and silane gas (SiH4) is introduced into a reaction chamber through a gas inlet port 6 at certain current while it is simultaneously discharged through an outlet port 7 so that a pressure within the reaction chamber is maintained at a fixed level. After that, the same potential is applied to the anode electrode 2 and to a shutter 3, and then a high frequency voltage is applied between a cathode electrode 1 and the shutter 3, whereby the silane gas is discharge- decomposed between the cathode electrode 1 and the shutter 3. After a lapse of several tens seconds from the discharge decomposition of the silane gas, the shutter is opened so as to cause the electric discharge between the cathode electrode 1 and the anode electrode 2. In this manner, the substrate is provided with only a hydrogenated amorphous silicon film that is deposited by stable electric discharge. If no discharge occurs with the application of a high frequency voltage, a high voltage is applied to the shutter 3 for a moment so that it triggers the discharge between the cathode 1 and the shutter 3.
