Title: Method and apparatus for resetting flat stepping motor from step out
Inventor: KOBA YOSHIKAZU
IPC: H02K41/03
Filed: 1993-07-09
Abstract: PURPOSE:To allow automatic resetting from step-out by providing jet ports opening horizontally in the direction eccentric to the center of a slider oh the side face thereof, and a valve for controlling compressed air supply to the jet ports. CONSTITUTION:A slider 2 is provided with ports 6, 8 for jetting the air horizontally to each side face 21 in predetermined directions at an acute clockwise and counter clockwide inclination angle theta. The jet ports 6, 8 are communicated with an air channel 52 for forming an air bearing 5 between the slider 2 and the stator 1 through control valves 7, 8, respectively. When an abnormal external force acts on the slider 2 to bring about a step-out state, the control valve 7 or 9 is opened to jet compressed air through the jet port 6 or 8. Consequently, rotary force is generated through reaction to rotate the slider 2. When an orthogonal relationship is substantially established with respect to X and Y axes, a self holding state is sustained by the magnetic attraction between the salient pole 13 of the stator 1 and the pole parts of electromagnets of X and Y axes caused by excitation of the electromagnetic drive unit for X axis or Y axis.

Title: Start judging method of electronically controlled internal-combustion engine
Inventor: TAKIMOTO TOSHIYUKI
IPC: F02D45/00
Filed: 1982-11-05
Abstract: PURPOSE:To suppress the rate of fuel consumption by stopping the increase of fuel after starting, when the number of revolutions of an engine has attained a specific value, even though a starter switch senses the start of engine. CONSTITUTION:The result of judgement by Step 100 will be ''NO'' immediately after turning-on of the starter switch, because the number of revolutions of the engine is below approx. 500rpm. Step 101 following it will give ''YES'' because it is immediately after turning-on of the starter switch, and ''1'' is entered into a starting time flag STA. Now the increase at the time of starting is made. If thereafter the engine speed rises to get over approx. 500rpm, the result of judgement by Step 100 becomes ''YES'', so that STA flag becomes ''0''. Accordingly fuel increase for starting period is stopped even while the starting switch is in ON, if the engine speed is over the reference value.

Title: Plasma processing device
Inventor: OMOTO YUTAKA
IPC: H01L21/302
Filed: 1994-08-19
Abstract: PURPOSE: To aim at the plasma processing utilizing chemical characteristic of the gas by separately controlling plasma density and the ion current. CONSTITUTION: A high frequency power source 15 makes the power at 150W with the frequency at 13.56MHz in a coil 14, and the electric field is generated in the vertical direction of a substrate 13 to be processed. The coil 14 is a Rogowskii coil formed by bending a wire from straight to circle so that the center axis of the helical coil goes along a columnar processing chamber. Micro wave power is set at 700W and the ion current is set at about 10mA/cm<2> so that the oxidation film etching speed are matched with each other. Since the micro wave power is lowered, plasma density is lowered in comparison with the conventional way, and dissociation speed of the processing gas CHF3 is lowered, and the Si etching speed is lowered in the condition that the SiO2 etching speed is maintained constant, and the etching speed selection ratio is improved to 15.  Since plasma density and the ion current can be separately controlled, plasma processing utilizing chemical characteristic of the gas can be performed.

Abstract: PURPOSE:To obtain a seeker apparatus capable of always turning a sensor to the direction of a target, by processing the signal and gimbal driving signal outputted from the first and second sensors and inputting the signal after selection to drive both gimbals. CONSTITUTION:For example, the signal A and gimbal driving signal B from radio wave sensor 3 are inputted to an operator 6 with a controller. Subsequently, the normality/abnormality of the signals from the sensors 1, 3 are judged to perform the selection of the signals and a gimbal driving signal D is outputted to turn the sensors 1, 3 to the direction of a target. By this selection of the signals, even when either one of the sensors, for example, the sensor 1 loses the target by the effect of a cloud, the signal of the other sensor, for example, the sensor 3 is utilized to make it possible to output the driving signal D. As a result, the sensors 1, 3 can be always held to the direction of the target. As a result, the other signal, for example, a distance or the timewise change rate thereof can be detected.

Title: Spindle servo circuit
Inventor: YOKOTA HACHIRO
IPC: G11B20/14
Filed: 1993-08-06
Abstract: PURPOSE:To ensure excellent playability at the ordinary time and to stabilize spindle servo when vibration occurs. CONSTITUTION:At the ordinary time when a shock detecting circuit 15 does not detect the shock, a control circuit 16 narrows a protection period in a synchronization protecting circuit 100, the detecting signal for synchronizing signal erroneously detected by a detecting circuit 9 for synchronizing signal due to flaws, stains, etc., is prevented from being inputted to a CLV control circuit 11 and good playability is ensured. On the other hand, when the shock detecting circuit 15 detects a shock, the control circuit 16 widens the protection period in a synchronization protecting circuit 100, makes the detecting signal for synchronized signal, which is correctly detected by the detecting circuit 9 for synchronizing signal but its timing is largely shifted due to the influence of jitter, surely input to the CLV control circuit 11 and the spindle servo is kept in a stable state.
