IPC: H02M1/12
Filed: 1992-04-27
Abstract: PURPOSE:To make it possible to bring an inverter under instantaneous follow-up control, by adding a reactor-transformer current signal to a capacitor signal, and obtaining a reactor current signal. CONSTITUTION:A current signal IAF at a capacitor 14 provided near a system bus line 3 in an injection circuit and a current signal IT equivalent to a secondary current of a reactor-transformer are taken up through a CT3 and a CT4, respectively, and these current signals are added in the same level to generate a reactor current signal IR. A reactor fundamental-wave current signal I1 is subtracted from the reactor current signal IR to obtain the higher harmonic reactor current signal, which is then added to a load higher harmonic current IL from a higher harmonic source 4 and they used as a current command value IREF to control an inverter 10. Consequently, the inverter 10 is brought under instantaneous follow-up control without changing a control algorithm.

Title: Built-up sleeve type rolling roll
Inventor: SANO GIICHI
IPC: B21B27/03
Filed: 1980-09-30
Abstract: PURPOSE:To increase the shearing resistance of the bonded zone in order to prevent the slip of a sleeve, by providing recesses in the inner surface of the sleeve and in the outer surface of an arbor, and by filling up these recesses with adhesives. CONSTITUTION:In order to prevent the slip at the bonded zone between a sleeve 2 and an arbor 1, projections 3' are formed in an adhesive 3; the size of the projection 3' is made larger than a gap (c+d) to be added to the bonded zone by the expansion of the sleeve 2 caused by its temperature rise. In the boundary surface 2' of the sleeve 2, projections 2'' and recesses 2''' are fomed; in the boundary surface 1' of the arbor 1, projections 1'' and receses 1''' are similarly formed; and in the adhesive 3, projections 3' are formed. Accordingly, under a condition that the sleeve 2 is heated to expand, a relation (a+b)>(c+d) is established; hereby, when shearing force is impressed upon the sleeve 2, and shearing force in the opposite direction is impressed upon the arbor 1, the strength of the bonded zone 3 nearly equal to the shearing strength of the projection 3' of the adhesive 3 at the engaging position is obtained.

Title: Method for quick reception rise
Inventor: TERAJIMA MASANORI
IPC: H04L27/14
Filed: 1989-05-31
Abstract: PURPOSE:To shorten the reception rise time by switching the time constant of AC coupling between a frequency discriminator and a base band part by an analog switch to faithfully discriminate continuous data of the same code. CONSTITUTION:At the time of reception rise, the time constant of AC coupling is determined by only a resistor 4 and a coupling capacitor 3 because an analog switch 6 is turned on, and the coupling capacitor 3 is quickly charged. When zerocrossing is detected in the output of a comparator 8 by a zero-crossing detector 10, the time constant of AC coupling is determined by the series value of resistors 4 and 5 and the coupling capacitor 3 because the analog switch 6 is turned off. Consequently, the cut-off frequency of a high-pass filter consisting of resistors 4 and 5 and the coupling capacitor 3 can be set to a sufficiently low value. Thus, the reception rise time is shortened because the time constant of AC coupling can be reduced at the time of rise, and even continuous data of the same code is satisfactorily discriminated because the low cut-off frequency is sufficiently reduced in the steady reception state.

Title: Optical circuit
Inventor: NISHIMOTO YUTAKA
IPC: G02B6/122
Filed: 1990-05-25
Abstract: PURPOSE:To stabilize the optical characteristics of guided light and to reduce its loss by forming plural recessed parts in the surface of an LiNbO3 base plate and forming a three-dimensional optical waveguides between the recessed parts. CONSTITUTION:Impurities are injected into the recessed parts 12 and 13 in the surface of the LiNbO3 base plate 11 from the surface of the LiNbO3 base plate 11 and the areas 15 and 16 right below the recessed parts 12 and 13 are made lower in refractive index than the area 14 between the recessed parts to form low-refractive-index layers 17 and 18. Namely, the area 14 held between the low-refractive-index areas 17 and 18 is relatively high in refractive index to form the three-dimensional optical waveguide 19 as a high-refractive-index layer. Thus, the three-dimensional optical waveguide 19 is formed at a position which is recessed from the surface of the LiNbO3 base plate 11 by depth (w), so it is hardly affected by environmental temperature and environmental pressure. Consequently, the optical characteristics of the guided light become invariably stable and the low-loss circuit is obtained.

Title: Travelling device
Inventor: URAGAMI FUKASHI
IPC: B62D57/024
Filed: 1994-05-27
Abstract: PURPOSE:To devise a uniaxial oscillating coupling means to travel on a travelling surface having a curved surface at an stable position by furnishing the uniaxial oscillating coupling means with an oscillating horizontal shaft having an oscillating surface practically orthogonal with an oscillating surface of each oscillating horizontal shaft of a biaxial oscillating coupling means as well as practically orthogonal with the travelling surface. CONSTITUTION:A relative angle of a main frame 4 and each oscillating frame 6 is changed on a surface of a biaxial oscillating coupling means 34 orthogonal with an oscillating horizontal shaft 40, and also the relative angle of the main frame 4 and each oscillating frame 6 is changed on the surface orthogonal with an oscillating vertical shaft. The relative angle of the main frame 4 and each oscillating frame 6 on the surface orthogonal with the oscillating vertical shaft 38 becomes less than 90 degrees. Additionally at this time, a distance between the central part of a connecting frame 8 and the oscillating horizontal shaft 40 of the biaxial oscillating coupling means 34 on the surface orthogonal with the oscillating vertical shaft 38 of the biaxial oscillating coupling means 34 is also reduced. Consequently, the central part of the connecting frame 8 moves to slide in the direction approaching the main frame 4 on an oscillating horizontal shaft 36 of a uniaxial oscillating coupling means 30.

Abstract: PURPOSE:To decide the presence or absence of the stress corrosion crack sensitivity in the in-pile structural materials of a light water reactor and to easily diagnose the corrosion resistance thereof by measuring the hardness of the above-mentioned materials. CONSTITUTION:An upper grid 6 is installed in a reactor pressure vessel 5. An arithmetic unit 3 and a display device 4 are provided on an operating floor 9 in the upper part of the reactor; further, an auxiliary hoist 8 is provided right above the vessel 5. A hardness measuring instrument 2 is hung down from the auxiliary hoist 8 and the hardness measuring instrument 2 and the arithmetic unit 3 are connected by a cable 7. The hardness measuring instrument 2 is first lowered down to a material to be diagnosed, i.e. the upper grid plate 6 by the hoist 8 and the hardness thereof is measured. The result of the hardness measurement is sent as an electric signal to the arithmetic unit 3. On the other hand, the expression data indicating the relation between the hardness and the corrosion resistance is incorporated into the arithmetic unit 3 and the previously measured hardness data of the upper grid plate 6 before the use is previously inputted therein. The corrosion resistance is easily diagnosed by computing and predicting the corrosion resistance level of the measuring point by using two sets of the above-mentioned data.
