IPC: G11B5/39
Filed: 1994-06-10
Abstract: PURPOSE:To obtain a magnetic head with which interchangeable reproducing by a magnetic head having no driving mechanism for tracking is made possible and a high-density recording and reproducing is possible even if track linearity exceeds a recording track pitch and a reproducing method therefor and a magnetic recording and reproducing device. CONSTITUTION:The magnetic head 80 is divided equally into N-pieces of magnetosensitive parts by (N+1) pieces of electrodes on magneto-resistance effect elements formed collectively with a track pitch of (n+1) times the track pitch Tp when the track linearity dL is n-times the recording track pitch Tp. Further, the reproduced signals of an N system from N-pieces of these magnetosensitive parts are discretely subjected to amplitude amplification and are outputted to a reproduction selecting circuit 85. This reproduction selecting circuit 85 executes the control of switches selectively to output only the signals contg. the target track signals to be reproduced to an adder 86. Then, the magnetic head 80 is capable of adding and outputting only the reproduced signals from the magnetosensitive parts including the target track signals at all times regardless of the scanning positions.

Title: Image blur preventing camera
Inventor: ENOMOTO SHIGEO
IPC: G03B7/093
Filed: 1990-05-18
Abstract: PURPOSE:To prevent image blur without using a correcting lens by providing a shutter forcedly closing means for generating a closing signal to a shutter when an angular velocity which is detected by an angular velocity detecting means is an allowable value or more after starting the opening operation of the shutter. CONSTITUTION:Angular acceleration sensors 12a and 12b are connected with comparators 16a and 16b through integration circuits 14a and 14b for integrating the outputs of respective sensors 12a and 12b and converting them into the angular velocity and absolute value circuits 15a and 15b. The output levels of the absolute value circuits 15a and 15b are compared with a prescribed voltage Vref by the comparators 16a and 16b, and then, in the case that these are smaller than Vref, the high-leveled voltage is outputted. When the angular velocity which is detected is the allowable value or more after starting the opening operation of the shutter, the closing signal is generated to the shutter. Thus, the image blur can be prevented without using the correcting lens.

Title: Method of measuring distance between dots* plane* and straight line
Inventor: SUTEIGU KAARE EIDORUFU
IPC: G01C15/00
Filed: 1980-09-17
Abstract: Instrument for measuring the distances of points from a plane or a straight line defined by means of the instrument. The instrument may also be used in marking out points on a plane or a straight line.The instrument functions by forming at least two mirror images (1, 2) of a measuring object (7) in such a manner that these images are differently oriented when viewed. This is accomplished in the simplest embodiment of the instrument by means of a prism 8 whose front face (6) is semi-reflecting whereas the other faces (4, 5) are perpendicular to each other and totally reflecting. If the measuring object is not on the defined plane or line (10) this will show up as a displacement of the differently oriented mirror images in relation to each other.The substantial novelty of the instrument is that all the images the relative displacement of which are employed for the read-out are mirror images of the measuring object and are formed without the need for focussing optical components such as lenses and concave mirrors.

Title: Rotor of rotating anode x-ray tube
Inventor: SUDOU SATOSHI
IPC: H01J35/10
Filed: 1977-10-31
Abstract: PURPOSE: To obtain a sufficiently powerful rotor of a rotating anode X-ray tube by providing a cylindrical part made from copper-chromium alloy including chromium at a specific weight ratio.  
     CONSTITUTION: A precipitation hardening-type copper-chromium alloy including 0.2 to 0.3% of chromium in the weight ratio has a very high tensile strength and hardness in comparison with pure copper; and though these values of pure copper are rapidly lowered according as a temperature rises, the copper-chromium alloy has these values prevented from being lowered much in a temperature below approximately 500 to 600°C, so that the strength of the rotor may be improved up to approximately 10 times overall within the temperture range above. Further, the lowering of electric conductivity dependent upon such a proportion of chromium content is slight in comparison with pure copper and does not matter at all on the characteristic as an induction motor rotor.

Filed: 1990-05-18
Abstract: PURPOSE:To facilitate the correction of grammar by correcting a structure tree shown for an input example sentence into a necessary syntax structure, generating automatically the grammar out of the corrected structure tree, and replacing the relevant part of the original grammar with the generated and corrected grammar. CONSTITUTION:A structure tree correcting part 1 analyzes the syntax of a given example sentence 4 of a program based on the prescribed grammar 5 and displays a prescribed structure tree 6. Then the part 1 corrects the tree 6 with the prescribed instruction input. A grammar generating part 2 analyzes the corrected tree 6 and generates the grammar corresponding to the tree 6 obtained by correcting the sentence 4 to use it as the corrected grammar 7. Then a grammar merging part 3 preserves the rules of the prescribed grammar 5 out of the grammar 7 in regard of the grammar rules equivalent to the grammar 5 and replaces the relevant part of the grammar 5 with the grammar 7. Thus it is possible to learn the necessary grammar out of the sentence 4 and to automatically correct the grammar.
