Abstract: PURPOSE:To continuously alter a resonance frequency by forming a variable capacitor of the projection, of a conductor plate, an insulation layer and a conductor ring in a high frequency magnetic field generator/detector used in a unclear magnetic resonance apparatus. CONSTITUTION:An equivalent series resonator is formed of a pair of H-shaped conductor plates 1 disposed symmetrically to form a hollow cylindrical unit, a chip capacitor 2 for capacitively coupling the opposed projections 1b of the plate 1, a pair of conductor rings 3 mounted through an insulation layer 4 at the inside of the projection 1b, more particularly top and bottom guard rings 3a, 3b, and a pair of insulators 5 with the rings 3. The rings 3 integral with the insulators 5, the layer 4 and the projection 1b from a variable capacitor. An electrostatic capacity generated therebetween is varied by moving elevationally the rings 3 with respect to the plates 1. In other words, the resonance frequency of the equivalent series resonator can be adjusted. Thus, the resonance frequency of an LC series resonator can be freely adjusted to respond to a magnetic field of wide range.

IPC: H04N1/407
Filed: 1987-02-17
Abstract: PURPOSE:To eliminate the need for offset adjustment due to secular change by acquiring a gain data making a white level at midposition coincident with a prescribed voltage and setting it to the gain initial value so as to correct the offset. CONSTITUTION:The white level at the middle part and a prescribed voltage A are compared and the white level of the middle part is made coincident with a prescribed voltage A by a gain data 52 and the gain data 52 is set to the shading correction section 7 as an initial data 50 of an automatic gain control section 8 by an initial data setting section 15. Prior to the shading correction, a white board is read and the gain data 52 making the output voltage of the middle part coincident with a prescribed voltage (reference voltage) A is acquired and set as the initial data 50 of the automatic gain control section 8. Thus, the illuminance of the prescribed position at the peripheral position starting the shading correction and the middle part is corrected identically, then using the acquired gain data 52 as the initial data 50, the white level of the prescribed position is made coincident with the reference voltage and the offset is eliminated.

Title: Rotary compressor
Inventor: MACHIDA AKIO
IPC: F04C29/06
Filed: 1990-02-16
Abstract: PURPOSE:To reduce a high frequency band noise generated due to the vibration of a structure by constituting a delivery port faced to a delivery valve with large and small bore portions, and so forming the large bore part as to be flat and shallow. CONSTITUTION:The small bore part 19 of a delivery port formed on a sub- bearing 6 is continuous to a compression chamber 17 in a cylinder 8, and a delivery flat part 20 related to the large bore part of the delivery port is connected to the small bore part 19 via a stepped part. Also, the delivery flat part 20 is open to the side of a delivery valve 14. When a roller 10 compresses refrigerant gas in a compression chamber 17 up to delivery pressure, the delivery valve 14 is suddenly opened and the delivery flat part 20 is decompressed. As the volume of the delivery flat part 20 is small, however, only small pulsation occurs. Also, connection between the delivery flat part 20 and the small bore part 19 changes in a stepped way and, therefore, the propagation of the pulsation from the small bore part 19 to the compression chamber 17 is restrained. As a result, pressure fluctuation acting on the roller 10 and a crankshaft 9 is reduced, and a vibration and noise in a high frequency band can be reduced.

When the coil 1 deviates from the traveling direction of the vehicle by a specific angle, the angle is used for correction to find the angle between the traveling direction of the vehicle and the direction of the earth magnetism. For the purpose, the proper value is inputted as the angle difference theta0 between the direction of the earth magnetism and the geographic south-north direction similarly to correct the azimuth of the traveling direction of the vehicle.
