Title: Formation of subterranean artificial ground
Inventor: ADACHI TOSHIHIKO
IPC: E02D3/12
Filed: 1987-03-17
Abstract: PURPOSE:To easily form an artificial ground at a given depth by a method in which excavation is made down to a given depth under the ground, an expanded bottom is formed on the bottom portion of the pit, and a hardener is packed into the connected expanded bottoms of a number of pits. CONSTITUTION:Excavation is made down to a given depth by a bottom- expanding excavator while injecting a stabilizer liquid for pit wall, and an expanded portion 1a is formed on the bottom of the pit 1. In the same way, adjacent pit 1 is formed and the expanded bottoms 1a are connected to each other. A hardening filler 5 is injected into the expanded bottoms 1a to form an artificial ground A under the ground. Thereafter, sheathing wall 7 is constructed and a pit is excavated to a depth 6. The artificial ground A which resists the pumping pressure of groundwater can thus be easily formed before excavation of pits.

Title: Manufacture of resin reinforced lumber, and resin reinforced lumber
Inventor: NAKAUE TAKAO
IPC: B27K5/00
Filed: 1991-03-26
Abstract: PURPOSE:To provide a manufacture of improving an increase of weight and a quality feeling of the surface which have not been avoided so far and caused by the fact that upon manufacturing resin reinforced lumber, conventionally generally polymeric resin is forcedly penetrated into lumber from its surface as a method of impregnating polymeric resin, and thereby the impregnation quantity can not be controlled with result that the whole part of lumber to be objected is unnecessarily impregnated with resin. CONSTITUTION:A cylindrical hollow part is formed in the fiber direction of lumber and polymeric resin is injected therein and, by the use of a centrifuge, the lumber is rotated and, by making use of centrifugal forces, resin liquid does not penetrate from the hollow inner wall surface, and thereafter the resin is polymerically cured, whereby the impregnation quantity becomes possible to be controlled and, besides, an unnecessary increase of weight becomes possible to be restrained, moreover, since the lumber is not impregnated with resin liquid, the quality feeling is not damaged, so that the use thereof can be expanded even in either field of high quality articles or wide application articles.

Title: Pellicle for lithography with improved light resistance
Inventor: SHIRASAKI SUSUMU
IPC: G03F1/62
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a pellicle for lithography consisting of a pellicle film which has a long life without deterioration or decomposition by light even when the film is irradiated for a long time with vacuum UV rays of short wavelength and which has high transmissivity for light and high performance without changes, by treating the pellicle film with fluorine gas to form a fluorinated layer on the film surface. SOLUTION: A pellicle film comprising an amorphous perfluoropolymer is treated with fluorine gas to form a fluorinated layer on the film surface. By forming a fluorinated layer of high density on the surface of the pellicle film, the fluorinated layer of high density causes recombination of opened bonds due to the radical reaction even under the conditions that the film absorbs light to produce radicals and deterioration is accelerated. Thus, deterioration of the film can be suppressed to an extremely low level. The fluorine atom content on the film surface is preferably at least >=60 mol.%. However, when the content exceeds 80 mol.%, the film strength may decrease, so the fluorine atom content is especially preferably controlled to 60 to 80 mol%.

Title: Protective apparatus for high-voltage multi-inverter
Inventor: OKAMATSU SHIGETOSHI
IPC: H02M7/48
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To attain cost reduction by inserting an AC current detector in only one phase of three-phase input of a transformer, thereby detecting short-circuit failure in a secondary circuit. SOLUTION: If two phases corresponding to the input power supply of a control circuit 54 of an inverter transistor in respective single-phase inverters are short-circuited, a power supply voltage drop detector 55 inside it comes into action and a breaker 2 is tripped through a logical sum element 72 from a logical sum element 73. If the short-circuit exists between one phase other than two phases corresponding to the input power supply of the control circuit 54 of the inverter transistor and other one phase, over-current appears, due to an influence of secondary short-circuit, in the phase in which an AC detector 3 mounted on the primary side of a transformer 4 is inserted.  As a result, even in the case of small input current in which an AC motor is variably driven at a low speed, secondary short-circuit can be detected by setting a detection level to a constant increase rate relative to a normal current value to be passed. Therefore, only one AC detector on the primary side of the transformer may be only added.

CONSTITUTION:A cut groove 2 is formed on the surface of an insulated magnetic substrate 1 of ferrite, etc., and a nonmagnetic material 3 is filled into the groove 2. Then an Ni-Fe alloy, for instance, is coated over a new surface finished with the same level as the surface of the substrate 1. Electrodes 5 and 6 are provided at both ends of the lengthwise direction of a magneto-resistance effect element 4, and the element 4 is set in parallel to the lengthwise direction of the groove 2. The upper end part of the element 4 is connected magnetically to the upper end part 9 of the groove 2, and the lower end part of the element 4 touches a recording medium 7. The surface 10 which is approximately rectangular to the element 4 touches the medium 7. The signal magnetization recorded to the medium 7 is led from the lower end part of the element 4 and then to the part 9 through the element 4. Then the signal magnetization is led to the surface 10 through the substrate 1 and returns to the medium 7. As a result, both the element width loss and the gap loss can be eliminated.

Title: Demodulator
Inventor: GOTO YUICHI
IPC: H04L27/227
Filed: 1995-03-22
Abstract: PURPOSE: To provide a QPSK(quadrature phase shift keying) demodulator which is capable of preventing a pseudo pull-in only if a simple circuit is added to a recetion logical circuit to be generally used, even when a reproduction carrier wave generates the pseudo pull-in. CONSTITUTION: At the time of a pseudo pull-in, a reception logical circuit 20 outputs a frame asynchronous alarm signal S5 because the frame information added an a transmission side becomes impossible to be detected. At the time of outputting the alarm signal S5, a reset signal generation circuit 50 generates an intermittent reset signal S4 and a selector 30 switches an APC(automatic phase control) signal source from a phase information generation circuit 25 output signal S3 to a clock signal of mark ratio 1/2. Thus, the APC signal is brought closer to a normal voltage value and the state is transferred from the pseudo pull-in to a normal pull-in state.
