Title: Scrap chopper abnormality detecting device
Inventor: KOSHIISHI HIROMICHI
IPC: B23Q17/09
Filed: 1993-10-15
Abstract: PURPOSE:To infallibly detect scrap chopper cutting abnormality by measuring by a magnetic sensor the magnetism of a cut piece which is cut by a scrap chopper, after magnetizing the cut piece with a magnetizing device and determining the abnormality of the chopper by the detected result of increase or decrease of the magnetic flux. CONSTITUTION:Trim scrap cut pieces out by a scrap chopper 35 into a specific length are magnetized when they pass through the inside of the magnetic field of a magnetizing device 1 provided on the outlet of the chopper 35. When the magnetized cut pieces pass through a magnetizing sensor 2, magnetic flux interlinking with a detecting coil varies. Then the peak value of the voltage induced to a detecting coil by increase or decrease of magnetic flux is measured and, when the voltage is exceeding the standard value, it is determined that the chopper 35 is functioning normally, while, when the voltage is below the standard value, cutting is determined to be abnormal because cut pieces are not discharged from the chopper 35. When cutting is abnormal, an alarm device 5 is operated and the slitter line is stopped by an on/off switch 6.

Abstract: PURPOSE:To electrically insulative fine wires from outer environment while conserving the strength of the wires by a method wherein an insulating fine wire is wound around a conductive fine wire protruded from the central part of multiple through holes made in a capillary. CONSTITUTION:An initial ball 13 is formed by releasing the first and second clampers 9 and 3 to melt down a conductive wire 1. A capillary 2 positioned above an electrode 10 is lowered to perform the pressure fixing step. At this time, a nonconductive fine wire 4 is bonded onto the initial ball 13 together with the conductive wire 1. When the capillary 2 is lifted by 1-10mm to be turned, the nonconductive fine wire 4 is wound around the conductive wire 1 to be electrically insulated. Next, after moving the capillary 2 to an outer connecting terminal 7 to be brought into contact therewith, the nonconductive fine wire 4 is cut off. Through these procedures, the strength of the wires can be increased while enabling the electrical contact between the two fine wires during the molding step to be avoided.

IPC: B41J2/30
Filed: 1989-10-04
Abstract: PURPOSE:To make a warming-up which is pleasant to the ear possible by a method wherein before printing a printing data, power connection which does not extend to printing is driven to a driving coil while the cycle is made variable and changed into a melody, in accordance with a detected value of a temperature detector. CONSTITUTION:When a printing data is sent to an impact printer, a temperature detector 1 detects a temperature by a resistance value of a thermistor 8 which is provided in an impact head 4. At this time, if the detected value is not higher than 10 deg.C, a data for warming-up is generated by a character generator 2, and a driving coil control unit 3 is made to output a power supply duration of e.g. 150musec with cycles of 116Hz, 132Hz and 148Hz respectively 10 times. By doing this, a driving lever 6 and printing wire 7 operate in a range which does not extend to printing, and the viscosities of an ink and lubricant between the wire 7 and a wire guide 10, and a lubricant between the lever 6 and a damper 13 decrease, or a part of them flies away, and printing without dots miss, uneven density can be performed. Also, since the driving cycle for a warming-up is made variable, a jarring noise can be changed to a melody which is pleasant to the ear.

Title: Rear focus type zoom lens
Inventor: TSUNODA TAKASHI
IPC: G02B15/167
Filed: 1988-10-17
Abstract: PURPOSE:To decrease the number of lens elements and to well correct various aberrations at the time of focusing by dividing a master lens group to a 1st lens group and a 2nd lens group, constituting the 2nd lens group movably on the optical axis and using this lens for focusing. CONSTITUTION:The master lens group IV is constituted of the two lens groups IV1, IV2. The lens group IV1 on the object side and the lens group IV2 on the image plane VI side are respectively constituted of 3 elements of lenses and, therefore, the master lens group is constituted of 6 elements of the lenses in total. The lens group IV2 is of the triplet configuration of convex, concave and convex and has the lens arrangement suitable for correction of various aberrations. The lens group IV1 has the effect of making the ray focused at the center of the image plane VI incident to the lens group IV2 in nearly parallel with the optical axis. The incident angle and height of the rays to this lens group IV2 are maintained nearly constant even if the lens group IV2 is moved on the optical axis for the purpose of focusing. The fluctuation in aberrations is thus decreased to the time of focusing. The various aberrations over the entire part of the zoom lens are thus well corrected over the entire focusing range by the master lens group IV in this way.

Title: Ultrasonic apparatus for diagnosis
Inventor: ISHIMURA TOSHIAKI
IPC: A61B8/14
Filed: 1988-10-17
Abstract: PURPOSE:To improve a distance resolution by providing a means for correcting the attenuation of a high-frequency component of an echo signal which is caused by a difference in an arrival distance between ultrasonic waves. CONSTITUTION:A variable frequency characteristic amplifier 10 is provided between a reception circuit and a pulse compression circuit. The frequency of an input chirp signal Vi is fixed when a gate voltage VG of FET 16 of the amplifier 10 is kept fixed. When the gate voltage VG is reduced linearly in accordance with the arrival distance of ultrasonic waves and the lapse of time, a resistance value between a source and a drain of the FET 16 increases in accordance therewith. Accordingly, the frequency of an amplifier 11 has a characteristic of its high band being raised, and the attenuation of a frequency component in the high band of the signal Vi is corrected effectively. Thereby an ultrasonic image being excellent in a distance resolution can be obtained invariably in a range from a shallow part to a deep part of a subject without increasing a side lobe of a time base of an impulse signal after the compression of a pulse.
