Title: Radiation-sensitive composition
Inventor: YAMAGUCHI ATSUKO
IPC: G03F7/075
Filed: 1993-09-22
Abstract: PURPOSE:To obtain excellent resolution and throughput by using a polyolefin with silyl groups introduced into side chains, polymethylmethacrylate, or silicon- contg. polymer which is a copolymer of these. CONSTITUTION:A radiation-sensitive material film 12 as a lower layer consists of 1mum thick novolac resin and a radiation-sensitive material film 13 consists of 0.2mum thick polytrimethyl silylmethylstyrene. These films are formed on a silicon substrate 11 by spin coating. By irradiating the substrate with soft X ray beams 5, the polytrimethyl silylmethylstyrene decomposes and vaporizes only in the irradiated part to give a pattern 15. Further, by performing reactive ion etching with oxygen, the oxygen gas plasma 16 oxidizes silicon in the pattern 16 to produce silicon dioxide. Thereby, the pattern 17 acts as an etching mask and a pattern 18 having 1mum height and 10 aspect ratio is obtd.

Filed: 1989-09-12
Abstract: PURPOSE:To obtain an ample pressing force with a comparatively low hydraulic pressure without using a hydraulic cylinder by expanding two thrust members through a wedge abutting on the outer peripheral surface of a rubber expanded by hydraulic pressure. CONSTITUTION:In a pressing operation, an object to be pressed is inserted between an active plate 2 and a passive plate 3 and hydraulic pressure is supplied uniformly from a hydraulic pressure generating device to the rubber tube 6 through a manifold 9 and a hydraulic pipe 8.

Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent the data of a terminal equipment in a parking lot from being altered by permitting communication only when the terminal equipment is accessed by a manager's ID number. SOLUTION: In the case of collecting the information, e.g. adjustment information of a certain parking lot 4 to be managed, a host device 2 in a maintenance company accesses a network adaptor 7 through a public line 3. A modem 10 receives the access and transfers data from the host device 2 to an MPU 9 through the public line 3. The MPU 9 compares an ID number included in the data with an ID number stored in a memory 8, and when both the ID numbers coincide with each other collects adjustment information for prescribed time from an MPU 6 built in an adjusting machine 5 and sends the collected information to the host device 2 through the modem 10. At the time the MPU 9 stores the ID number and a date executing the collection of the adjustment information in a memory 8 as the application state of a network.  Then, the MPU 9 ends the communication and releases the modem 10 from a communication line connected to the public line 3.

Title: Semiconductor element
Inventor: TAKEI KOJI
IPC: H01L39/22
Filed: 1985-10-25
Abstract: PURPOSE:To settle a problem of an increase in electric resistance resulting from thinning of a base electrode layer, by forming the base electrode layer of a superconductor. CONSTITUTION:The material of a base electrode layer 8 is a superconductor of a Pb Te compound obtained by doping thallium (Tl) at 1.0atom%. When cooled down to a temperature 1K, the base electrode layer 8 is put in a superconducting state, and sheet resistance lowers below the limit (0.01OMEGA) of detection of a measuring instrument. Since the base electrode 8 is formed of a superconducting material, the electric resistance of the base electrode layer can be made zero by setting the operating temperature of an element below the superconductivity transition temperature (Tc) of the material of the base electrode. Therefore, this constitution enables the suppression of an increase in the electric resistance resulting from the thinning of the base electrode layer, which is a problem of a conventional MBT element, and thus the base electrode layer by far thinner than the base electrode layer of the conventional MBT element can be formed.
