Title: Method and apparatus for ultrasonic wave image
Inventor: TODA KOJI
IPC: G01N29/22
Filed: 1990-10-11
Abstract: PURPOSE:To obtain the images of the shape and the elastic property of a sample based on the received reflected wave by arranging a wave transmitting means for exciting the specified mode in leaking surface acoustic waves and a wave receiving means on the surface of water, transmitting an ultrasonic wave beam which is focused on the sample in the water, and scanning the sample. CONSTITUTION:A leaking surface wave element 26 having the wave transmitting and receiving means is arranged on the surface of water in the tank 16. When an RF signal 106 is imparted into the element 26 from a radio-frequency-pulse generator 52, a surface acoustic wave is excited. A part of the wave becomes the leaking surface acoustic wave which is propagated in the water 12. The specified mode in the surface wave is excited, and the wave is transmitted to a sample 14 in the water 12. The reflected wave is received with the wave receiving means of the element 26. A moving stage is sequentially moved by first and second control signals 100 and 102 of a scanning and controlling part 24 to scan the ultrasonic wave beam of the element 26. The received signal with the element 26 is processed in a reflection-intensity detecting means 56 and an image forming means 66, and the result is displayed on an image display part 72. Thus, the images of the shape, the elastic property and the like of the sample can be obtained.

IPC: G11B7/09
Filed: 1988-10-31
Abstract: PURPOSE:To enable the fast and accurate moving operation of an optical head to a prescribed position by disposing one pair of magnets between one pair of bobbins around which driving coils are wound and a head main body fitted in between these bobbins and forming lines of magnetic force by these magnets toward the head main body side and individual bobbin sides. CONSTITUTION:One pair of the magnets 7 and 8 are disposed between one pair of the bobbins 3 and 4 wound with the driving coils 31 and 41 and the head main body 21 fitted in between the bobbins 3 and 4, and the magnetic lines of force are formed by the magnets 7 and 8 toward the side of the head main body 21 and the sides of the individual bobbins 3 and 4. Then, lines of magnetic force toward the side of the optical magnetic head 2 and the sides of individual magnetic yokes 5 and 6 are formed by one pair of the permanent magnets 7 and 8. Consequently, the number of magnets 7 and 8 can be reduced, and the disposing work of the magnets 7 and 8 can be simplified, while the disposing accuracy of the magnets is improved, and hence electromagnetic force to be given to the head main body 21 and the individual bobbins 3 and 4 can be uniformalized. By this method, driving force to be given to the optical head 2 is stabilized, and then the optical head 2 can be operated to move quickly and accurately into the prescribed position.

Title: Image forming material
Inventor: TAKATO TAKAKI
IPC: G03C1/72
Filed: 1984-12-26
Abstract: PURPOSE:To obtain an image forming material suitable for use in the formation of a fine pattern by combining a donor with a salt which acts as an oxidizing agent and then releases an anion capable of forming a charge-transfer complex with the donor by quick degradation when light is irradiated on the salt. CONSTITUTION:This image forming material contains an electron donating compound and an org. salt and/or an inorg. salt which is reduced with light and generates an anion. The material can form an image by the difference in color tone between the state of the mixture before the irradiation of light and a state after the formation of a charge-transfer complex by the irradiation of light. For example, when the donor and the photodegradable compound are dispersed in a polymer carrier or incorporated into the molecular skeleton of the carrier, an image can be formed by the difference in absorption in the ultraviolet and visible regions between light irradiated and unirradiated parts. An image can be also formed by the difference in solubility in an org. solvent between the state of the mixture before the irradiation of light and a state after the formation of a charge-transfer complex by the irradiation of the rays of light.

Filed: 1990-10-11
Abstract: PURPOSE:To efficiently supply an erasing current even in time of high frequency by providing this rotational erasing circuit with a control means and controlling ON/OFF of the output current outputted from an oscillation means. CONSTITUTION:Power supplied to a terminal T1 is transmitted to the inside of a rotary cylinder by a power supplying means 3, then supplied to the oscillating means 2 through an electromagnetic conversion means 1. During the execution of rotational erasing, a high level rotational erasing signal TTL is supplied to a terminal T2 and converted into impedance by an operation amplifier OP1 in the control means 4 and the converted impedance is transmitted to the means 2. Thereby, transistors(TRs) TR1, TR2 are turned to operation state and the means 2 is turned to a resonance state by a capacitor C1 and a reactance component of a head H1 in the means 1. When the rotational erasing is stopped, the TTL is turned to a low level and resonance is stopped. Consequently, an unnecessary floating variable can be reduced and an erasing current can be efficiently supplied even in the high frequency state.

Title: Winding method for wire
Inventor: HACHITSUKA TAKASHI
IPC: B21C47/04
Filed: 1985-12-06
Abstract: PURPOSE:To perform the winding of the coil of good shape by changing the rotary speed of the reel of a winder periodically and by giving a big curvature to the wire in case of the rotary speed of the reel being slower than the reference and a small curvature in case of faster speed. CONSTITUTION:In case of the rotary number of a reel 3 being slower than the wire rod, the advance quantity of a bending roll 6 is in the retreated position from the case of the reference diameter and is moved so that the curvature of the wire in winding becomes larger by reducing the bending quantity to be given to the wire 1. The winding diameter becomes smaller according to the number of reel turnings being increased in order and reaches to the reference state once again, so the roll 6 is advanced accordingly and the feeding curvature corresponding to the curvature thereof is taken. The wire bending curvature is reduced by increasing the bending quantity onto the wire 1 by advancing the roll 6 by cylinder 7 when the speed of the reel 3 is further increased and the winding diameter becomes smaller.
