Title: Rotary anode structure for x-ray tube
Inventor: KOBAYASHI KAZUO
IPC: H01J35/10
Filed: 1981-06-24
Abstract: PURPOSE:To increase the thermal resistance of the shaft of a rotor by increasing the diameter of the said shaft, which supports a target, from the target to the shoulder of the rotor. CONSTITUTION:The diameter of a shaft 2a of a rotor 2 becomes smaller from a shoulder 2b of the rotor 2 to a target 1. The shape of the above shaft 2a is not limited to one straight line, but may be a shape formed by connecting not less than two straight lines. In addition, the shaft 2a may be formed so that it has a hollow center. As a result, the mean sectional area of the shaft 2a of the rotor 2, which develops the maximal bending stress equal to that of the conventional structure, becomes about 70% that of the conventional structure. Conseqneutly, the thermal resistance of the shaft 2a can be increased.

IPC: G03F1/00
Filed: 1981-06-24
Abstract: PURPOSE:To realize high productivity and low cost, by forming a composite pattern of the 1st and 2nd patterns based on only the basic 1st pattern which can be easily produced. CONSTITUTION:A composite pattern of the 1st pattern 1 and the 2nd pattern 2 which encloses the pattern 1 with a space secured between them is formed with use of a photomask. For the production of this photomask, a visible pattern 1A is obtained by enlarging the pattern 1. Then an latent image pattern 2A of the pattern 2 is formed on a mask base material with use of the pattern 1A. Furthermore, a latent image pattern 1B of the pattern 1 is formed, and both patterns 1 and 2 are made visible after giving a development process to the mask base material. In such a way, the production is excluded for the pattern 2 that is hard to produce. As a result, the productivity is increased with a reduction of cost for a photomask.

IPC: G11B3/095
Filed: 1980-07-17
Abstract: PURPOSE: To realize a correct inter-music detection even with a record disk having different reflection factors or an unevenness, by comparing the detection signal of an inter-music sensor and the sample holding value of the detection signal.  
     CONSTITUTION: The output of an inter-music sensor 1 is sampled by a switching element 3a which is turned on and off via a clock generator 4 to be held at a capacitor C. This held value is compared with the detection output of the sensor 1 through a differential amplifier 5, and this difference of value is processed by a comparator 6 to which the threshold value is set. If the reference of value is larger than the threshold value, and area where the sensor output is large incomparison with the sound groove is decided as an area between the pieces of music. In such a way, a correct and stable inter-music detection is ensured even with a record disk having different reflection factors or an uneven reflection. An inter-music detection is also made possible during a performance of different relative speeds to a sensor in the same way as the lead-in mode.

Title: Conductive adhesive composition, anisortropic adhesive film provied with the same, and connecting method using the film
Inventor: NAKAGAWA TORU
IPC: H01B1/20
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent short circuiting and perform an electrical connection allowing a high density mounting by setting a radiation curable resin in an adhesive resin to a quantity sufficient for controlling the flowing property of the adhesive after curing and capable of sufficiently absorbing the stress generated by heat cure of a thermosetting resin. SOLUTION: Since an adhesive resin 26 has high flowing property when it is not exposed to radiation, the adhesive resin 26 between an electrode pad 10 and an electrode terminal 14 is eliminated in crimping, so that a conductive particle 28 makes contact with the electrode pad 10 and the electrode terminal 14. Mean while. since the adhesive resin 26 exposed to radiation substantially shows no flowing property about the pressurizing force in crimping, the conductive particles 28 will not make contact with each other. This, in an anisotropic adhesive film 22, a conducting part is formed only in the thickness direction between the electrode pad 10 and the electrode terminal 14 by emission of radiation, and the formation of short circuits between electrical connecting parts can be prevented in parts other than that.

Filed: 1991-04-26
Abstract: PURPOSE:To realize accurate step driving without requiring an encoder by switching an ultrasonic oscillation generating means for driving and a standing wave oscillation generating means for stopping appropriately through a switching means. CONSTITUTION:An oscillator ultrasonic wave generating means applies a voltage having frequency in ultrasonic range onto an oscillator piezoelectric element 11. Consequently, the oscillator piezoelectric element 11 is excited to rotate a rotor 17 by a quarter of the standing wave oscillation mode wavelength of the rotor 17. A switching means then switches the oscillator ultrasonic wave generating means to a rotor standing wave generating means which thereby applies a standing wave driving voltage onto a rotor piezoelectric element 16. The rotor 17 is then fed so that the positions of pectinated teeth 13 are aligned with reference to a rotor standing wave oscillation node set at half of the standing wave oscillation mode wavelength. According to the invention, the rotor 17 can accurately be driven in step without requiring any encoder.
