Title: Active magnetic surveying method
Inventor: OOKUBO YASUKUNI
IPC: G01V3/28
Filed: 1987-10-07
Abstract: PURPOSE:To survey an underground magnetic body distribution with high accuracy according to the position relation between the installation positions of solenoids and an observation point and a produced secondary magnetic field by producing a magnetic field under the ground by many solenoids arranged in a survey area at intervals. CONSTITUTION:A receiver 3 is placed on the ground surface 4 and the solenoids 3 are arranged in a pit. In another case, the receiver 3 is put in the pit and the solenoids 2 are arranged in another pit. Assuming many magnetic bodies 1 are distributed in an E shape in a two-dimensional plane, the two-dimensional space of 200mX200m thickness of the magnetic bodies 1 is divided into, for example, 8X8 cells and the magnetic susceptibility of each cell is found. When the receiver is placed on the ground surface 4, extraction accuracy is high inside an inverted triangle formed having the ground surface 4 as its base and height based upon the pit. Thus, the solenoids 2 as artificial magnetic field production sources are installed to increase the information amount, thereby measuring the distribution of the magnetic bodies 1 with high accuracy.

Title: Sealed gasket for explosion-proof cell
Inventor: SHINODA KENICHI
IPC: H01M50/184
Filed: 1984-12-03
Abstract: PURPOSE:To obtain a gasket, with high reliability, which is securely operated under lower pressure without making thickness of the thin face part extremely thin by making a molecular orientation of polymer on the surrounding part of a breaking groove formed in the sealed gasket, approximately in parallel to the groove. CONSTITUTION:The sealed gasket 20 for explosion-proof alkaline cell is an injection molding product of polypropylene or the like, integratedly formed of the boss part 22, inner cylindrical part 24, corn-shaped slant face part 26, and outer cylindrical part 28. When the gas pressure inside the cell becomes abnormally high, the gasket inner cylindrical part 24 is broken with a longitudinal groove 24a along the axial direction serving as a starting point. In this sealed gasket 20, the molecular orientation of polymer on the surrounding part of the longitudinal groove 24a is in parallel to the longitudinal 24a. For this reason, this part is inclined to be cracked along the longitudinal groove 24a, so the residual thickness of the longitudinal groove 24a need not be made extremely thin. Therefore, the control of dimension during molding is performed more easily, and the dispersion of operating pressure, caused by molding error and temperature, can be reduced. Polypropylene, on account of being strong in molecular orientation, is suitable for composing the sealed gasket.

IPC: G02B6/12
Filed: 1987-10-08
Abstract: PURPOSE:To improve a handling property and workability by making use of the characteristic that the 1st layer near a metallic mold is deformed at the larger degree than the 2nd layer adjacent thereto when the laminated sheets of a thermoplastic resin are subjected to hot press-molding with the metallic mold. CONSTITUTION:An acrylic resin 21 forming the laminated sheets 2 is thicker than a vinylidene fluoride resin 22. Namely, the respective sheet thicknesses are selected in the following manner: While core layers 32 are formed in accordance with grooves 11, 12 when the laminated sheets 2 are not press-molded in the metallic mold, the acrylic resin 23 and the vinylidene fluoride resin 22 are deformed to a mountain range shape in the inside thereof and the acrylic resin 21 is substantially separated from the groove parts and other parts of the metallic mold. Furthermore, the vinylidene resin 22 in the part deformed to the mountain range shape forms a clad layer 33 and the core layer 31 is formed on this clad layer 33. Although the outside surface of the core layer 31 comes into contact with the air, the refractive index of the air layer is sufficiently lower than the refractive index of the core layer 31 and said layer can be regarded as the clad layer 33. The handling property and workability are thereby improved.

Title: Fm demodulation circuit employing phase locked loop
Inventor: NISHIJIMA KAZUNORI
IPC: H03D3/02
Filed: 1989-09-29
Abstract: PURPOSE:To always obtain a constant PLL loop gain even when the amplitude of an input signal is fluctuated by detecting the output amplitude of an automatic gain control circuit with an amplitude detection circuit so as to control a gain of a phase error amplifier. CONSTITUTION:A phase error amplifier 9 consists of a variable gain amplifier. The output amplitude of an automatic gain control circuit (AGC) 5 is detected by an amplitude detection circuit 6, the detection output is amplified by a DC amplifier 7 and supplied to a limiter 8. The limiter 8 limits the output amplitude of the amplifier 7 and its output is fed to a phase error amplifier 9 via a gain variable terminal 13 as a gain control voltage. Thus, when the output amplitude of the AGC 5 is decreased in response to the level fluctuation of an FM demodulation signal, the gain of the amplifier 9 is increased. Moreover, when the output amplitude of the AGC 5 becomes larger, the gain of the amplifier 9 is decreased. As a result, the PLL operates so that its loop gain is always constant.

IPC: G11B21/02
Filed: 1991-09-05
Abstract: PURPOSE:To continuously position magnetic heads by providing small-sized magnets on a coil and a holder, which drive the lamination of arms and spacers as one body, and on an upper substrate and supplying power to the coil to equalize driving forces to inner and outer cylinders. CONSTITUTION:Magnetic heads 1 are fixed to and supported at front ends of plural arms 2, and spacers 2 which alternate with arms 2 keep intervals of arms 2 fixed. A coil 7 drives the laminated body of arms 2 and spacers 3 as one body, and small-sized magnets 11 are provided on a holder 4 facing an upper substrate 9 and on the substrate 9. When a power source is turned on to supply a current to the coil 77 a driving force is generated in the coil 7 by the interference between the magnetic field generated in the coil 7 and that of a magnetic circuit 8. Since the supply current of the coil 7 is controlled to equalize the driving forces to inner and outer cylinders, oscillation of magnetic heads is suppressed. Thus, magnetic heads 1 are continuously positioned between arbitrary cylinders on the magnetic disk.
