Title: Method and device for generating plasma
Inventor: KAKEHI YUTAKA
IPC: C23C16/511
Filed: 1991-03-26
Abstract: PURPOSE:To generate a plasma in discharge area with a satisfactory uniformity by changing the phase velocity in a waveguide to uniformalize the microwave electric field at the time of extending TE11 mode by a taper tube. CONSTITUTION:A magnetron 1 is mounted on a rectangular guide-wave 3 to generate an electric field of TE11 mode. A taper tube 6 is also regulated in taper angle and taper length so as to extend the TE11 mode, and a microwave tries to progress in the taper tube in TE11 mode. At that time, since a quartz tube 9 has a curvature, a difference in phase speed is caused between the center and the ends when the microwave propagates in the plasma, and the phase speed becomes slower the more it is closer to the center, whereby a more uniform electric field distribution can be obtained in the whole discharge chamber 7. Thus, a high density plasma can be generated with a satisfactory uniformity within the discharge chamber 7.

IPC: H02P8/00
Filed: 1987-03-16
Abstract: PURPOSE:To smoothly control a device without generating oscillation and noise, by switching a magnetic field to be leading phase to a rotor angle in a short period, with micro-step driving. CONSTITUTION:Acceleration displacement from an acceleration displacement table 9 is set to be increased as the counter value of an interval counter 7 is increased. In the meantime, an acceleration phase difference from an acceleration phase difference table 11 is set to be leading phase at 90 degrees. The acceleration displacement and phase displacement are added to each other, and are added to windings 25, 27 via an electrical angle register 15. As a result, according to the displacement of a rotor angle, in a minute period, phase in a magnetic field is changed. Accordingly, the sudden and extreme change of torque applied to a rotor 28 is not generated.

Title: Intermittent reception system
Inventor: MASAOKA NOBUHIRO
IPC: H04W52/02
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To operate a PHS terminal for a long time by decreasing an intermittent reception interval when a remaining energy of a battery is sufficient and increasing the intermittent reception interval when the battery is consumed so as to suppress consumption of the battery. SOLUTION: An energy detection section 6 detects a voltage output of a battery section 5. In the case that the voltage is maximum, that is, the detection section 6 detects that the remaining energy is full, a radio communication control section 1 is activated in a timing of an incoming call of a 2nd group to which its own terminal belongs and the terminal receives the signal. In this case, let a transmission period of an incoming signal of each group be a time T, the intermittent reception interval is 3T. In the case that the battery voltage is less than a preset voltage, that is, the detection section 6 discriminates that the remaining energy is small, the intermittent reception interval is set longer by one cycle, a voltage value a little smaller than the present setting value is set to the energy detection section 6 and the intermittent reception interval is 6T.

Abstract: PURPOSE:To continuously and effectively measure data of the inner diameter of a tube by projecting a light beam to the inner wall of the tube while restricting rotating parts as much as possible, and detecting the reflecting light or scattering light by a position detecting device through a condensing lens. CONSTITUTION:A light beam projected into a tube 10 is reflected at the surface of the wall, and the reflecting light is reflected by a detecting prism 23 mounted to a motor 21 to a position detecting device 27 through a condensing lens 25. The rotation of the motor 21 is transmitted to a projecting prism 19 via a transmission system 29 such as a gear or the like, so that the motor 21 is rotated synchronously with the detecting prism 23. Accordingly, the light beam is continuously projected in a circumferential direction of the inner wall of the tube 10, and the reflecting light is continuously detected by the detecting device 27. The reflecting light is input to signal processing circuits 33, 34 through amplifiers 31, 32 and further input to a distance operating circuit 35. The distribution of the intensity of the reflecting light detected by the detecting device 27 is changed in accordance with the change of the inner diameter of the tube 10. Therefore, if the corresponding output signal is operated, the distance to the inner wall of the tube 10, i.e., inner diameter of the tube can be calculated.

After the resin 11 has been hardened, the outside layer is removed from the mold-releasing sheet 6. As the heat-shrinkable sheet 6 of the outermost layer shrinks by the heat treatment through the above- mentioned procedures, the cushion material 9 receives compression force from the outer circumferential part, it is deformed by said compression force, then the mold- releasing sheet 6 is also pushed inward, and lastly, it is formed into the shape formed in parallel with the recess and protrusion of the outer circumference of the coil. As a result, the occurrence of resin trap part on the outer circumferential part of the coil can be prevented, and the lowering of the quenching current can also be prevented.
