Title: Broad-bank spin locking method
Inventor: FUJIWARA TOSHIMICHI
IPC: G01N24/08
Filed: 1988-10-24
Abstract: PURPOSE:To improve sensitivity to efficiently measure NOE even if there is inequality of RF waves by performing the movement of magnetization between a locking direction and a lateral plane before and after a constant spin locking period of RF strength. CONSTITUTION:For example, when an RF1 is made spin locking magnetic field strength, the magnetic field to off-resonance magnetization in which a vertical component corresponds to RF2 is made RF'1 and the angle of RF'1 to RF1 is made theta. The size of the magnetic field RF2 by 170 deg. pulse is twice as large as RF1 and the vertical component RF2 is not varied. The direction of apparent RF'2 magnetic field is inclined to about theta/2. Accordingly, when a 170 deg. pulse is applied, the off-resonance magnetization MX0 rotates in 180 deg. around the RF'2 and looks toward the direction of the RF'1. When the spin locking magnetic field is applied under this condition, the magnetization MX0 is locked, if the phenomenon of an NOE occurs and the 170 deg. pulse is also applied after the specified hours, the magnetization MX0 looked toward the direction of the RF'1 rotates in 180 deg. around the RF'2 and faces the X direction.

Title: Electromagnetic bearing controller
Inventor: MATSUSHITA OSAMI
IPC: F16C32/04
Filed: 1991-09-20
Abstract: PURPOSE:To suppress the imbalanced vibration by detecting the position in the radial direction of a rotor from the X and Y directions, controlling the electromagnetic coil electric current so as to hold the rotor at a set position, inputting the detection signal into a revolution speed tracking filter, and addition/subtraction-inputting each direction signal into a servocircuit. CONSTITUTION:The rotor displacement signal (x) in the X direction is inputted into a control circuit 4, and the result of the calculation is inputted into a power amplifier 5, and the control electric current is allowed to flow in an electromagnet coil 2. In case of Y direction, the same passes. The displacement signals (x) and (y) are inputted into a tracking filter 7 as the revolution synchronous component, and only the revolution synchronous components (xN) and (yN) among the displacement vibration components of the rotor are extracted. The differential signals y'N and -x'N are considered for the output signals xN and yN, taking account of only the imbalanced vibration components. In order to apply the damping action in the Y direction, the xN signal is multiplied by alpha, and the result is addition-inputted to the X-direction channel. While, in order to apply the damping action in the X direction, the (yN) signal is multiplied by -alpha, and the result is addition-inputted into the X-direction channel. Accordingly, the damping performance for the forward vibration of the rotor can be improved.

Title: Printing position correcting mechanism
Inventor: TSUCHIDA NOBUHIRO
IPC: H04N1/23
Filed: 1990-10-05
Abstract: PURPOSE:To correct a deviation in a latent image caused by the deformation of a lens and to prevent the deviation in printing width and a printing position by providing a temp. sensor detecting a temp. in the vicinity of the lens, and controlling the exposure starting time of an LD unit and a driving power source based on the detected signal of the temp. sensor. CONSTITUTION:The surface of a photosensitive drum 1 is electrified by an electrifier 2, and the latent image is formed on the surface of the photosensitive drum 1 by an exposing part 3. The latent image is developed by a developing unit 4. Then, the temp. sensor 8 sends a detecting signal corresponding to the temp. inside the exposing part 3 to a control part 9. The control part 9 controls the timing of the starting of an exposure and the driving frequency of the LD, based on the sent signal. In other words, the temp. inside the exposing part 3 is risen, the control part 9 delays the starting of the exposure. Conversely, when the temp. is dropped, the part 9 quickens the starting of the exposure. Simultaneously with this, when the temp. is risen, the driving frequency of the LD is reduced. Conversely, when the temp. is dropped, the frequency is increased. Thus, the positional deviation of the latent image caused by the deformation of a plastic lens 10 is corrected.

IPC: H05B7/148
Filed: 1988-10-25
Abstract: PURPOSE:To restrict a shortcircuit current at a low level by providing a current detecting means in a circuit for applying a current to an electrode of a DC arc furnace, and controlling an output current of a rectifier corresponding to an increase ratio of an overcurrent detected by this current detecting means. CONSTITUTION:An overcurrent is detected by a current detecting means 10 at the time of a shortcircuit in an arc furnace 9, and by seeing an increase ratio of this overcurrent, a contact condition of an electrode 3 with a scrap 4 can be detected. A thyrister of a rectifier 2 is controlled based on the increase ratio of the overcurrent to reduce an output of the rectifier 2 largely if the increase ratio is large, while it is reduced a little when the ratio is small, so a current in the middle of a shift can be reduced to a constant level in either case. A shortcircuit current produced at the time of a shortcircuit in the arc furnace 9 can be controlled to be at a low level.

Title: Co-generation device
Inventor: HARA MICHIOKI
IPC: F02G5/02
Filed: 1988-10-24
Abstract: PURPOSE:To reduce the nitrogen oxides in the exhaust and increase the heat recovery efficiency by providing a controller for outputting the open signal to an intake air escape valve to raise the exhaust temperature when the oxygen concentration showed by the detecting signal from an O2 sensor is more than the predetermined value. CONSTITUTION:When the output of a diesel engine 1 lowers, the air-fuel ratio is practically increased, and the oxygen concentration in the exhaust is increased by the air to be excessively supplied and the exhaust temperature lowers. Then, an O2 sensor 8 provided in an exhaust pipe 5 detects the oxygen concentration to output the detection signal to a controller 12, and the controller 12 outputs the open signal to an intake air escape valve 7 provided in an exhaust pipe 4 when the oxygen concentration is more than the predetermined value. Then, since the intake air escape valve 7 opens so as to escape a part of the air pressure supplied from a supercharger 3 to an engine 1 to the air, the air-fuel ratio is reduced, and as result the exhaust temperature rises. Consequently, the heat recovery efficiency of a heat exchanger 11 is improved and the nitrogen oxides is reduced by the catalyst of an exhaust emission control device 10.
