Title: Magnetic flux control circuit
Inventor: ORIME SHINKEI
IPC: H01F7/18
Filed: 1978-11-27
Abstract: PURPOSE:To obtain a magnetic flux control circuit incorporating the self-diagnosis function by causing the necessary output in case some fault occurs to either one of the signals of the phase control, the reset current control and the overcurrent detection each. CONSTITUTION:When the phase control signal is supplied to terminal 1 and the phase control is carried out normally after decision given to control signal 0 through decision circuit 21, set gate 18 is blocked. Then the reset signal is applied to terminal 3 to supply the necessary current to coil 10-A of magnetic core 9 via resetting exciter 8. When the reset current is normal, output Q' of FF6B is set to 1 to be applied to gate 16 of quality decision circuit 15. If the overcurrent occurs to the reset current, reset comparator 14 detects it. And then set gate 18 and reset gate 7 are blocked to avoid the buring of reset exciter 17 and exciter 8. Also gate 16 is turned off even if some fault takes place at either one of the phase control, the reset current control and the covercurrent detection. And the output of deciding FF6C turns to logic 0 to secure the decision for the quality of the magnetic flux control circuit.

IPC: G03B21/625
Filed: 1992-05-12
Abstract: PURPOSE:To lessen the generation of moire patterns and to eliminate video disturbance by having plural lenticular lens elements having lenticular lens shapes on light incident surfaces and providing fine rugged shapes which emit the incident light on at least the two points on the surfaces in the same direction on the surfaces of these elements. CONSTITUTION:The lenticular lens sheet is formed with the fine rugged shapes 42-1, 42-2,... on the surfaces of the lenticular lens elements 41 on the light incident side. The light from the various positions of the lenticular lens elements 4 are made to arrive at an observer by these fine rugged shapes 42-1, 42-2,... and, therefore, not only the dark ray parts but video light eventually arrive at the observer and the intensity of the dark ray part weakens. Then, less dark and hardly visible moire patterns are obtd. and the disturbance on videos is eliminated when the lenticular lens sheet is combined with a Fresnel lens sheet. The lenticular lens sheet is easily produced by extrusion molding of a material contg. thermoplastic resin and nonthermoplastic beads.

Title: Rear-wheel steering controller for vehicles
Inventor: FUKUNAGA YUKIO
IPC: B62D5/26
Filed: 1984-07-17
Abstract: PURPOSE:To improve car steering stability, by setting a selector valve for steering rear wheels, to be steered in the reverse direction to a front-wheel steering direction, to an operating position at a rear-wheel steering position in time of more than the specified car speed while to a neutral position at a non-steering position, respectively. CONSTITUTION:In time of more than the specified car speed, a controlling device 31 keeps a selector valve 29 at an operating position with a signal out of a car speed sensor 32. Under this condition, if right steering operation takes place, front wheels 1 are steered to the right, while rear wheels 2 are steered to the left. When a car speed goes beyond the specified speed, the car speed sensor 32 indicates this fact to the controlling device 31. Receiving this indication, when the controlling device 31 judges that rear wheels 2 are in a non-steering position with a signal out of a position sensor 33, it causes the selector valve 29 to be situated in a neutral position 29b, disabling these rear wheels to steer. However, this control unit 31 judges that rear wheels are in the steering position, it keeps the selector valve 29 at the operating position 29a whereby such a possibility that these rear wheels 2 are locked as being left steered intact is prevented from occurring.

IPC: B62D11/08
Filed: 1981-09-17
Abstract: PURPOSE:To perform a pivotal turn around a ground point gradually by providing an inching valve capable of being operated with a foot. CONSTITUTION:As the inching spool 61 of an inching valve G is depressed with a pedal, the pressure oil begins to escape through the notch 61b of the spool 61 to a port L through a slant face 61a and the pressure oil flowing into a clutch unit through an auxiliary speed change oil hydraulic control valve E is decreased in accordance with the amount of the pedal depression, then the half-connected condition of the clutch is created at the strength proportional to the decrease. When the pedal is further depressed, the pressure oil escapes to the port L through the notch 61b instead of through the slant face 61a, and the pressure oil of an oil pressure unit flowing from the auxiliary speed change oil hydraulic control valve E escapes to a drain port D through a notch 61c, thereby the auxiliary speed change unit is put in a neutral condition and the vehicle is stopped.

IPC: G01D5/20
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To make precisely detectable the position of a shaft to be detected, even when the characteristic of a coil is irregular by comparing the detection signal of the shaft to be detected, on the basis of the difference between two oscillation signals which are outputted respectively from a coil for detection and a coil for reference. SOLUTION: In a comparator 10, an oscillation signal from a coil 5 for reference is inputted to a noninverting input terminal, an oscillation signal from a coil 1 for detection is input to an inverting input terminal according to the movement size of a shaft 2 to be detected, and a detection signal Vsig which is obtained by amplifying the difference between both oscillation signals is output from an output terminal. In this case, even when the characteristic of the coil 1 itself for detection becomes irregular, an irregularity due to the temperature in the characteristic of the coil itself is offset when the difference between the oscillation signal to be output from the coil 1 for detection according to the insertion and passage state of the shaft 2 to be detected and the oscillation signal to be output from the coil 5 for reference is found.  Thereby, the position of the shaft 2 to be detected can be detected precisely.

Title: Reflection mirror antenna
Inventor: FUKAMI AKINARI
IPC: H01Q19/19
Filed: 1983-08-12
Abstract: PURPOSE:To obtain a very effective antenna which keeps stable and excellent line quality by arranging a focus of a subreflection mirror while displacing it by a prescribed displacement on an antenna axis from the focus of a main reflection mirror. CONSTITUTION:In constituting the antenna where the focus f2 of the subreflection mirror 2 and the focus F of the main reflection mirror 1 are not made coincident, but shifted on the antenna axis 4 by a distance of DELTAf, there is a disturbance in the phase distribution on the aperture of the main reflection mirror 1 and a phase difference is caused between the center in the aperture and the circumferential part. As a result, the directivity characteristic of the antenna is shown in characteristic 6 in broken lines of a figure. That is, the notch produced between the main beam and the 1st side lobe is compensated and also the side lobe level is increased. Thus, even if the apparent direction of an incoming radio wave due to the phase relation between the direct wave and the reflected wave caused by the reflection on the surface of the sea in using this antenna as a reception antenna is changed, the received electric field is not lowered. Thus, the very effective antenna capable of keeping stable and excellent line quality is attained.
