Patent JP-H10196155-A (JP)
Title: Vibration isolation mechanism
Inventor: YAMADA MASAAKI
IPC: E04H9/02
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To reduce vibrations in the vertical direction effectively by installing a fluid column relatively bearing upper structure, a tank, in which capacity is changed by the relative displacement of upper and lower structure and a connecting pipe connecting the tank and the fluid column. SOLUTION: When a foundation 1 is displaced upwards, the side wall and top plate 10 of a tank 9 are moved integrally to an upper section. Since a support plate is fixed to the upper structure 10, on the other hand, a section between the top plate 10 and a bottom plate 11 is separated relatively, and the capacity of the tank 9 is increased. Oil in a connecting pipe 12 is flowed into the tank 9. Consequently, oil in quantity equal to the quantity of oil flowed in flows from the inside of the oil column 3 into the connecting pipe 12. As a result, the length of the oil column 3 is shortened by length size equal to the upward displacement of the foundation 1, and displacement is offset by the shortening of the oil column 3.  When the foundation 1 is displaced downwards, the capacity of the tank 9 is reduced, oil in the tank 9 flows into the connecting pipe 12 side, and the length of the oil column 3 is lengthened by size equal to displacement. Accordingly, vertical movement can be inhibited largely.

Abstract: PURPOSE:To improve the flame retardance of a crosslinked polyolefin resin, without causing the lowering of crosslinking efficiency and surface appearance, by compounding a silicone-grafted polyolefin with a flame retardant at a low temperature, and crosslinking the composition with water in the presence of a silanol condensation catalyst. CONSTITUTION:A polyolefin (e.g. polyethylene) is added with an unsaturated alkoxysilane and an orgaic peroxide, subjected to the silicon grafting reaction, added further with a flame retardant, and kneaded at a temperature near the melting point of the polyolefin. The composition obtained thereby is crosslinked with water in the presence of a silanol condensation catalyst. The flame retardant is, e.g. halogen-containing flame retardant, aluminum hydroxide, etc., and is dried to a water content of <=50ppm, preferably <=10ppm before use.

Abstract: PURPOSE:To contrive a positive, smooth operation of a device for generating a high pressure fluid by using a double acting hydraulic cylinder by a construction wherein two spool valves are actuated simultaneously in association with each other. CONSTITUTION:The arrangement is made such that a hydraulic pressure is fed through a pressurized fluid supply port 41 of a pushing spool valve 40 into a head side chamber  P of a hydraulic cylinder 21, whilst the fluid pressure in the rod side chamber R is allowed to flow out through a fluid pressure supply and discharge port 24 and a communication port 45' of a pushing back spool valve 40' and thence into a fluid reservoir.  At the same time, the fluid pressure in the head side chamber flows out therefrom through a fluid pressure supply and discharge port 23', a communication port 45 and a discharge port 43 and into the fluid reservoir, whilst the fluid pressure for the rod side chamber is introduced from a fluid pressure supply port 41' and through a communication port 44' and a fluid pressure supply and discharge port 24'.

IPC: H04M7/06
Filed: 1990-01-24
Abstract: PURPOSE:To eliminate the need for care for the difference of signal formats entirely by discriminating a type of a signal format and supplying the converted signal format based on the result of discrimination to a center exchange. CONSTITUTION:A signal format discrimination section 13 discriminates the type of a signal format used by a floor exchange 11 to which a caller (subscriber 15) belongs and the type of a signal format used by the floor exchange 11. Moreover, when it is discriminated that the type of the signal format of the caller and the type of a signal format of a called party are coincident, the format is sent to a center exchange 12 and when discriminated to be dissident conversely, the signal format converted into the signal format of an opposite party is sent to the center exchange 12. Thus, the exchange processing by the common line signal system is implemented without caring for the difference of the signal format at all.

Abstract: PURPOSE:To obtain a flat LOCOS region, in which an abnormal region is hardly generated, in excellent productivity, and to improve the degree of integration by forming a fine groove section to the periphery being in contact with the LOCOS region of an active region and burying a nitride film into the fine groove section. CONSTITUTION:A third SiO2 oxide film 15 is formed through heat treatment in an oxidation atmosphere oven. The oxide film 15 is not formed on the surface of an Si3N4 film 14a because the oxidation of the Si3N4 film 14a of a side surface is very slow. Only the Si3N4 film 14a of the side surface is removed, and Si in the peripheral section of a stepped difference 10a is exposed. Si In the peripheral section is etched in a (self-alignment) manner to form a groove 16 intruding to the side surface. The whole surface is coated with a third Si3N4 film 17 to bury the groove 16. Only the Si3N4 film 17 in the side surface and the groove 16 remains through etching, and an Si wafer 10 in which the Si3N4 film 17 is buried is completed. The oxidation intrusion of Si to a section as an MOS type active region surrounded by the third Si3N4 film 17 is inhibited, and an insulating film, in which a bird-beak region (A) is suppressed, i.e. a LOCOS, can be formed.

After the voltage induced with the coil 3 is amplified to an intended value with a signal amplifier 5, it is converted to DC voltage with a detector 6. This DC voltage is measured with a known means, whereby the level of the surface 8 is measured.
