Filed: 1983-12-16
Abstract: PURPOSE:To control the rotation of a brushless motor with a simple and inexpensive structure by detecting the position by a position detection brush and a position detection plate at the motor starting time and by an induced counterelectromotive force generated by the rotation after the motor is started. CONSTITUTION:A magnet 3 is mounted on the inside of a rotor housing 2, and position detection brushes 4, 4' made of thin metal plates having elasticity are mounted on the upper surface side.

Further, after the motor is started, the position of the rotor 2 is detected by detecting the induced counterelectromotive force generated by the rotation by the position detection coil. The brushes 4, 4' are separated from the plates 15a-15c by the centrifugal forces of the weights 5, 5' at this time.

Abstract: PROBLEM TO BE SOLVED: To permit the observation and image formation of image information in a good state without parallaxes by adequately setting each set of the constitution of a display optical system for guiding luminous fluxes to the observer's eyeballs and an image pickup optical system for forming the image information of the outside word onto an image pickup element surface. SOLUTION: The optical axis 101a of the display optical system 101 and the optical axis 1c of the see-through optical system 103 as the optical axis of the image pickup optical system 102 are aligned by an optical path separating means 4 and is made coaxial with the eyeball optical axis 1a. Since the joint surface 4a of prism bodies 9a and 9c has a prescribed spectral transmittance characteristic, most of the wavelength mainly of, for example, <=550 nm emitted from a liquid crystal element 2 is mostly reflected and the observer observes the image information of the blue green formed on the liquid crystal element 2 as an enlarged image. Only the light mainly of <=550 nm of the light from the outside world is reflected and the outside world image of the blue green is formed on a CCD 3.  The surface E3 and surface 4 of the prism body 9c and the surface E2 of the prism body 9a function as the see-through optical system 140 for the light of >=550 nm in wavelength as a whole.

Abstract: PURPOSE: To provide an electrodeless discharge lamp with easy start. CONSTITUTION: An electrodeless discharge lamp 5 is constituted by arranging four rolls of spiral high frequency exciting coils 21 withe high conductivity and circular cross section in the surroundings of a bulb 11. One end of the high frequency exciting coil 21 is connected to a high frequency oscillating circuit and the other end is connected to an earth. The center of the bulb 11 is slipped from the central axis of the high frequency exciting coil 21, displaced to one side of the high frequency exciting coil 21, and the distance L1 from the center of the bulb 11 to one end of the high frequency exciting coil 21 is shorter than the distance L2 to the other end.  Since the bulb 11 is displaced to one side of the high frequency exciting coil 21, magnetic field is strengthened in a part where the bulb 11 and the high frequency exciting coil 21 are approached to increase the electric field. Thereby, discharge breakage is made easy to make starting easy.

Abstract: PURPOSE:To obtain a high film forming speed by a mathod wherein a cluster ion beam is deflected by a deflecting means, and the deflected ion beam only is introduced to a substrate. CONSTITUTION:The cluster beam 24 emitted from a cluster beam source 6 is first ionized in an ionization chamber 14a, the cluster ion beam 26a generated in the ionization chamber 14a is accelerated by an accelerating electrode 22a, it is deflected by a deflecting electrode 30a and introduced into a substrate 4.

Title: Moving picture compressor
Inventor: MATSUI SHINICHI
IPC: H04N7/30
Filed: 1992-08-14
Abstract: PURPOSE:To simplify the structure of the compressor by predicting motion based on a weight mean component calculated for frequency shift on a Wavelet conversion axis so as to eliminate the need for the processing of conversion  time   shift   conversion on the conversion axis. CONSTITUTION:The compressor is provided with a Wavelet converter 51 applying Wavelet conversion to picture data and a weight mean device 54 taking weight mean of conversion plane data on a conversion axis loop for motion prediction, and the weight mean device 54 divides internally conversion axis data to calculate shift data and the Wavelet converter shifts the phase (shifts the frequency). Since the shift is calculated on the conversion axis, the processing of conversion   time   shift   conversion having been required for a conventional compressor is eliminated. Then the prediction on the conversion axis loop is simply implemented regardless of the elimination of the processing of conversion, shift and inverse conversion on the conversion axis and then the configuration of the compressor is remarkably simplified.

Title: Collision preventive device for medical device
Inventor: KIKUCHI HIROSHI
IPC: A61N5/10
Filed: 1988-09-26
Abstract: PURPOSE:To reliably prevent contact of a patient with a device by a method wherein a contact detecting circuit causes a given current to flow when a contact detector does not detect contact and during a normal state, and shuts off a current when the contact detector detects contact. CONSTITUTION:When a short circuit plate 1 short-circuits terminals 10a and 10b with each other, a contact detecting circuit forms one circuit throughout a range of from a power source 21 to an earth through a relay 22, a switch 4, a wiring 7a, the terminal 10a, the short-circuit plate 1, the terminal 10b, and a wiring 7b. With the switch 4 closed, the relay 22 is charged with a given current, and the relay 22 is in a working state. When a contact detector 60 detect contact, the switch 4 is opened, and since no current flows to the relay 22, the relay 22 is brought into a normal state, and a relay contact 22a is opened. In this case, an interlock circuit 24 immediately stops the motion of a medial device. For example, the generation of X-rays is stopped and movement of a moving part is stopped.

Title: Power amplifier
Inventor: MATSUMOTO KAZUHIRO
IPC: H03F3/68
Filed: 1989-09-14
Abstract: PURPOSE:To control an output power without decreasing the efficiency by providing a capacitive active element to an output matching circuit, and varying the bias of the active element so as to change the bias of the amplifier circuit while matching the circuit, thereby controlling the output power. CONSTITUTION:A bias VD3 to a varactor diode 13 is varied for the output control to change the capacitance of the varactor diode 13. Thus, an output matching circuit 14 at the output control is optimized. This is equivalent to the fact that an impedance at a point A as shown in the Smith's chart is moved to a point B having a low output by increasing the capacitance of the varactor diode 13 connected in parallel with the amplifier circuit. Thus, the output is changed from 33dBm to 28dBm or so by moving the point from A to the B while the efficiency is nearly 80%, which means decrease by 4-6dBm, but no remarkable decrease is caused.
