Title: Ultrasonic motor
Inventor: SUZUKI KAZUMA
IPC: H02N2/00
Filed: 1988-11-15
Abstract: PURPOSE:To achieve reciprocal rotary motion easily through a simple and thin structure by pressure contacting a slider onto the outer circumferential face of a vibration disc unit provided with piezoelectric elements vibratable in radial mode and circumferential sliding mode then rotary driving the slider. CONSTITUTION:When electrical signals in ultrasonic range are applied in parallel onto a radial mode piezoelectric element 6a and a circumferential slip mode piezoelectric element 2, inherent radial mode of a vibration unit u1 is generated through the piezoelectric element 6a. When a slider is pressure contacting with the outer circumferential face of a drive member 3, pressure contact force is amplified under radial mode of the vibration unit u1 and rotary force functions in the slip mode thus producing rotary motion of the slider. In the reverse cycle, contracting mode prevails under radial mode to reduce pressure contact force so as to idle the vibration unit u1. Since the process is repeated during initial half cycle, the slider rotates unilaterally.

Title: Phase locked loop frequency synthesizer
Inventor: WATANABE YASUNOBU
IPC: H03L7/10
Filed: 1992-10-27
Abstract: PURPOSE:To reduce a pull-in time by selecting a reference frequency sequentially from a larger frequency toward a smaller frequency till an object frequency is divided out by a prepared reference frequency and setting a frequency division ratio corresponding to the reference frequency when the object frequency is divided out to a variable frequency divider in a PLL loop. CONSTITUTION:When a command of an object frequency fout is given to a frequency division ratio setting circuit 7, a control section 7c discriminates whether or not the object frequency fout is divided out by a reference frequency prepared in advance and when the object frequency fout is not divided out, the reference frequency is being changed from a larger frequency toward a lower frequency. When the object frequency fout is divided out by the reference frequency, a control section 7c allows 1st and 2nd storage sections 7a, 7b to respectively output frequency division ratios M, N' at that time. Thus, it is not required to select all the prepared reference frequencies and to make arithmetic operation and the pulling is finished when the object frequency is obtained and the pull-in time is reduced.

Title: Optical head device
Inventor: TANAKA HIDEKI
IPC: G11B7/135
Filed: 1986-12-05
Abstract: PURPOSE:To obtain a sufficient focus sensitivity in a state that an S/N is not deteriorated, without adding a new optical member, by working in a concave shape an end face opposed optically to a photodetector of an optical member for leading a light beam which has passed through a recording medium, to the photodetector. CONSTITUTION:Reflected light containing a focus error signal from a recording medium is made incident on an optical waveguide 6 from the upper part of the paper surface, and a part thereof is diffracted by a diffraction grating 8a and made incident on photodetectors 7a, 7b in the optical waveguide 6. The end face 6a of the optical waveguide 6 opposed to the photodetectors 7a, 7b is worked in a concave shape, therefore, a composite focal length of a focal length of the diffraction grating 8a and a focal length of the concave part 6a becomes longer than a focal length of only the optical member in which a concave shape is not worked in the end face of the waveguide. Accordingly, in a state that a DC light (light which is not varied against a focal movement) level is constant, against a variation of a minute luminous flux, its variation can be detected with high sensitivity.

Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent foreign matter from being deposited in a downward flowing-out direction changing chamber for elimination of maintenance work for eliminating foreign matter by making a position where fluid flows in the downward flowing-out direction changing chamber from a clearance generated between a plug and a seat ring, eccentric from the central position of the downward flowing-out direction changing chamber. SOLUTION: When the first and second plugs 10, 11 are pulled upwards by a diaphragm operating device to form a flow passage between upward and downward flowing-out direction changing chambers 8, 61 and a fluid flowing-in opening 2, the fluid flowed from the fluid flowing-in opening 2 flows in the bottom surface of the downward flowing-out direction changing chamber 61. The flowing-out center to the downward flowing-out direction changing chamber 61 is near its inner side surface 61a, therefore, the fluid flows out a fluid flowing-out opening 3 while generating a clockwise vortex with the position where it flows into the downward flowing-out direction changing chamber 61 from the second seat ring 13 centered.  The vortex agitates foreign matter remaining on the bottom part of the downward flowing-out direction changing chamber 61 and makes it flow into the fluid flowing-out opening 3 easily, thus it is possible to prevent foreign matter from being deposited.

Title: Method for controlling temperature of lamp
Inventor: SAITO HIROYUKI
IPC: G03G21/20
Filed: 1988-11-14
Abstract: PURPOSE:To detect and control the temperature of a fluorescent lamp accurately by switching a heat quantity to the lamp on its way at warmup of the lamp. CONSTITUTION:A facial lamp heater 7 is fitted to the surface of a glass tube 23 of a fluorescent lamp 2 opposite to the side formed with an optical aperture 24 of the glass tube 23 and a thermister 8 as a temperature sensor is fitted to nearly the centre of the lamp heater 7. With the lamp 2 heated, since the lighting of the lamp 2 heats up itself at a low temperature at the start of warmup, the temperature of the temperature sensor is not excessively increased even when the thermal inertia of the tamp 2 is small. Moreover, when the temperature of the lamp 2 reaches a prescribed value or over, since the heating by the lighting of the lamp 2 and the lamp heater 7 are used at the same time, the lamp reaches the setting temperature in a short time. Thus, the temperature of the lamp is detected without error and the temperature of the lamp is kept accurately to the setting temperature.

Title: Manufacture of josephson element
Inventor: TANABE YUZURU
IPC: H01L39/24
Filed: 1987-11-19
Abstract: PURPOSE:To facilitate the formation of a Josephson junction by forming a superconducting layer having a higher critical temperature than that of a superconductor by an ion implanting method on the surface of the superconductor made of a polycrystal or a single crystal. CONSTITUTION:Oxide superconductor 1 which exhibits superconductivity by cooling it with liquid nitrogen is employed as a superconductor of a bulk section, and its surface undergoes ion implantation for a higher transition temperature. In this case, the shape of a region 2 to be ion implanted is so controlled by a mask as to become a suitable shape for forming a Josephson junction. The critical temperature of the ion implanted region 2 rises so that this region can transite to a superconducting state at higher temperature than the transition temperature of the bulk section which is not ion implanted. Thus, the Josephson junction can be easily formed merely by partly ion implanting to the superconductor.
