Title: Fastening nut for pipe joint
Inventor: YAMAJI MICHIO
IPC: F16L19/03
Filed: 1993-05-07
Abstract: PURPOSE:To provide a fastening nut for a pipe joint by which corotation of a nut and a joint constituting member can be prevented reliably. CONSTITUTION:A fastening nut 4 for a pipe joint is composed of a nut body 16 and a thrust ball bearing 6. An inward annular projecting part 21 having an inside diameter slightly smaller than an outside diameter of a right side lace 18 is arranged close to an inward flange 11 of the nut body 16. The right side lace 18 is inserted forcibly inside of this annular projecting part 21. When a nut 4 is fastened gradually, though the right side lace 18 of the thrust ball bearing 6 rotates integrally with the nut body 16, a left side lace 17 of the thrust bearing 6 is brought into close contact with an outward flange 13 of the second joint member 2, and does not rotate together with the nut body 16.

Title: Optical recording and reproducing method
Inventor: ASAZUMA YASUNORI
IPC: G11B7/24035
Filed: 1991-05-13
Abstract: PURPOSE:To prevent light damages and to enhance S/N of reproduction characteristics by executing optical recording while using an inorg. photochromic material added with a rare earth element executing wavelength light emission in a prescribed electron state and executing reading out by the light emission of a prescribed wavelength. CONSTITUTION:A recording layer 2 having the inorg. photochromic material added with the rare earth element is deposited on a base body 1 and a protective film 3 is deposited thereon, by which an optical recording medium 4 is constituted. The light emission of 2nd wavelength light lambda2 is not obtainable with the recording layer 2 by the excitation of 1st wavelength light, lambda1 in the 1st electron state of rare earth ions. The rare earth ions are changed to the 2nd electron state by the photoionization by the irradiation with 3rd wavelength light lambda3. The wavelength light lambda2 is emitted by the excitation of the wavelength light lambda1. The recording of information is executed by the 1st and 2nd electron states with the wavelength light lambda3 as recording light. The reading out of the information is executed by the presence or absence or the magnitude of the emission of the wavelength light lambda2, using the wavelength light lambda1 as the exciting light.

Abstract: PURPOSE:To obtain a piezoelectric transformer capable of raising two input voltages of different frequencies by making a generation part composed of a pair of output parts which are formed at prescribed intervals. CONSTITUTION:This transformer is composed of a plate-shaped driving part piezoelectric element 18, which is polarized in the direction of its thickness and has electrodes 20 and 22 on both its ends, and generation part piezoelectric elements 14, 16 which are fixed on respective sides facing each other perpendicularly to these electrodes planes of the driving part piezoelectric element 18 and are polarized perpendicularly to these fixture planes. Said respective generation part piezoelectric elements 14 and 16 in such a piezoelectric transformer 10 are composed of two pairs of output parts 41, 43 and 45, 47 which are respectively formed via prescribed gaps 40. Accordingly, oscillation appears in an in-phase mode, in which the output parts with the gaps 40 on both their sides are oscillated with similar phases, and in a negative mode, in which they are oscillated with phases shifted in 180 degrees from each other. Two desired input voltages of different frequencies can be hence raised by setting a gap width W1 in an appropriate value.

Abstract: PURPOSE:To protect viewer's eyes from tiring due to the viewer's approaching to the screen too closely and to relieve the viewer's exposure to the ultrasonic waves by providing first - third oscillators and an ultrasonic wave element which generates the ultrasonic waves being driven by the output of the said oscillators. CONSTITUTION:The pulse width t2 of a monostable multivibrator 8 is so set that the t3 which is obtained by adding the t2 to the pulse width t1 of the second oscillator 2, becomes equal to t which is the time from when the ultrasonic wave is emitted by the element 4 till the time when an ultrasonic wave receiving element 5 receives the reflecting signal. By means of the output from a gate circuit 9, whether or not the distance between the viewer and the screen surface is such one as needing a control of the operational state of the television receiver is decided. In such way, the viewer's eyes are prevented from tiring due to a too close distance to the screen surface.

Title: Display unit
Inventor: OGURA KOUZABUROU
IPC: G01R5/14
Filed: 1978-09-04
Abstract: PURPOSE: To prolong the lifetime of a display unit by eliminating its trouble and by reducing aging variation, by employing a simple constitution where a ball only floats in a liquid in an airtight container wound with a coil.  
     CONSTITUTION: Airtight container 1 of a non-magnetic substance is a cylinder with one end made spherical for display part 2. The moment a current flows through coil 7 wounded around its out circumference, a magnetic field is generated around coil 7 and ball 4 moves in liquid 5 so that a vertical magnet will be horizontal. As a result, the magnet in ball 4 can be seen standing upringht through display part 2 while the current is not flowing and it can be seen at a level once the current flows. Namely, ball 4 turns by 90°. Since the rotational angle varies with the strength of the current, it serves as a simple meter.

Abstract: PURPOSE: To attain the opening and closing of a door and its locking with simple structure by fixing a lateral arm to the door support, mounting the door on the tip of the lateral arm, and coaxially installing a driving shaft at the lower part of the door support through a differential gear.  
     CONSTITUTION: When a manual switch operates with a door opened and when the motor 14 and the driving shaft 12 revolve, the revolving load of the door support 1 does not operate the differential gear 18 differentially due to only the door weitht and the door support 1 reolveds with the driving shaft 12 in a body. The door 6 moves toward the direction where the entrance for getting on an off closes by the link operation between the lateral arms 4 and 5 and the lateral rod 9. The upper end of the door makes contact with the weather strip. When the revolving load of the door support 1 increases, the differential gear operates differentially. As a result, the door support 1 is pushed up by the spring engagement with the shaft and the upper edge of the door enters the groove on the upper edge of the entrance. A limit switch opens and the motor 14 stops.

IPC: G03G15/08
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent toner from being transferred and attached to a second toner-carrying means in the case of unnecessary. SOLUTION: A developing device is provided with a developing roller 14 which holds the one-component toner on it, and an intermediate roller 17 which abuts on the developing roller 14 and a photoreceptor 1 for holding an electrostatic latent image on it and which forms a toner image by transferring and attaching the toner from the developing roller 14 to itself, thereby attaching the toner to the electrostatic latent image on the photoreceptor 1. At the time of recording-sheet-area-outside-development between the recording sheets, when the plurality of sheets are consecutively inserted, a bias which is applied to the developing roller 14 is changed and, thus, an electric field direction between the developing roller 14 and intermediate roller 17 is made different from that used at the time of recording-sheet-area-development.

Abstract: PROBLEM TO BE SOLVED: To absorb energy of time cycle vibration of a structural member by providing a first spring and a second spring which include rings provided with rods connected between the rings and have the stiffness which determines resonance frequency at which a first barrel part and a second barrel part vibrate. SOLUTION: A first deflection body 36 has circular rings 37 and 38. A rod 40 is thin between the rings 37 and 38 and a diameter of a cross section thereof is small at a central position thereof so that the first deflection body 36 plays the role of a spring. A second deflection body 55 is formed by a rod 59 having a circular cross section and rings 57 and 58. A retaining ring 51 enters an end part of a housing and comes in contact with the ring 58 of the second deflecting body 55. By changing the stress which acts on the rods 40 and 59 of a deflecting body assembly, the stiffness of the spring is changed to change resonance frequency and to adjust a vibration absorbing device. Consequently, the vibration energy can be absorbed by the vibration of a durable mass body 32 and a motor assembly 50 in the optimum condition.
