IPC: G10K15/04
Filed: 1989-02-23
Abstract: PURPOSE:To output neither a holding alarm nor a nonholding alarm for a live alarm which continues for a specific time by giving respective warning output circuits independent timing times. CONSTITUTION:Live alarms which are inputted from respective live alarm input terminals I1 - IK are inputted to input terminals of an (n)-stage shift register SFT. A clock generating circuit OSO outputs a clock with an mn/ (m; timing time, n; number of stages of the shift register) second period and the clock is inputted to the clock terminal of the (n)-stage shift register SFT. The (n)-stage shift register SFT outputs an alarm from a holding alarm output terminal 02K after its timing every time (n) clocks are inputted to the clock terminal. Namely, when the live alarm continues (m) seconds later after its generation, the alarm is generated. Then the live alarm is reset to reset an after-timing operation holding alarm. Consequently, an alarm is prevented from being generated unless the alarm continues for (m) seconds.

Filed: 1995-01-20
Abstract: PURPOSE: To improve the durability of a reed while maintaining its acoustic characteristics by subjecting at least the vibrating part thereof to a surface treatment with a silicone resin. CONSTITUTION: This reed is composed of a vibrating part 2 showing a tapered shape toward a supporting part and a supporting part 3 and a reed is used as its blank. Both of the vibrating part 2 and the supporting part 3 are subjected to an impregnation treatment with a 3-aminotriethoxysilane which is, for example, a silane coupling agent, as the silicone resin so as to attain a thickness of about 1μm. As a result, the durability of the reed is improved and the blowing feel is improved. The saving of the labor for impregnating the reed with water at the time of use is possible as well. Further, the reed is normally held stored in a case, etc., for the purpose of mechanical protection. The insertion and removal of the reed into and out of the case are facilitated by subjecting the reed to the surface treatment by the silicone resin.  In addition, the damage of the reed is lessened at the time of taking out and in the reed.

Filed: 1993-03-05
Abstract: PURPOSE:To make an operation efficient by a method wherein, when a roll of paper is started so as to be wound, the roll of paper is fed slower than a coil velocity and a paper velocity is changed over so as to take a back tension when it is restricted by the coil velocity. CONSTITUTION:A coil-diameter detector 6 outputs a coil-diameter detection signal (CD). A comparator 9 compares the rotary-body-veclocity detection signal of a pulse pickup 8 with a coil-velocity signal. An adder-subtracter 7a adds the CD to a comparison signal and subtracts the CD from the comparison signal. A velocity control amplifier 10 amplifies an addition-subtraction signal, and it inputs a velocity control signal to an adder-subtracter 7b through a limiter circuit 14. The adder-subtracter 7b adds the velocity control signal to the output-current detection signal of an inverter 16 and subtracts the velocity control signal from the output-current detection signal. A current control amplifier 15 amplifies an addition-subtraction signal, and it inputs a current control signal to the inverter 16. Then, a roll of paper is wound on a coil, a tension setter 12 is actuated, a tension detection contact 13 is changed over to the side of a tension setter 11, and a tension setting signal is input to the limiter circuit 14. The limiter circuit 14 limits the velocity control signal of the velocity control amplifier 10 to a tension set value.

Filed: 1993-03-05
Abstract: PURPOSE: To strictly, easily and cheaply keep a target position of a central irradiation portion of an X-ray irradiation beam by thrusting a fixing device installed in an X-ray tube to the outside penetrating through a protection casing. CONSTITUTION: A fixing device 7 is installed in an X-ray tube 1, projecting to the outside penetrating through a protection casing 3 and can be directly united with a holding portion 6 of an X-ray irradiation device. Relative accuracy of a target position of a central irradiation portion Z to the fixing device 7 chiefly depends on installation accuracy of the fixing device 7 to the X-ray tube 1. Therefore, since accuracy of the target position of the irradiation portion Z relative to the holding portion 6 in the neighborhood of the X-ray irradiation device depends only on manufacture accuracy of the fixing device 7 and the holding portion 6 and the installation accuracy of the fixing device 7 to the X-ray tube 1, the target position of the central irradiation portion of a beam irradiated from the X-ray irradiation device can be strictly kept in an easy form and at little expense.

Title: High manganese steel having good wear resistance to earth and sand
Inventor: FUJIKURA MASAKUNI
IPC: C22C38/00
Filed: 1979-04-14
Abstract: PURPOSE: To enhance weld padding property and resistance to wear due to earth and sand by a method wherein contents of C and O 2  is reduced from, and elements such as Cr and V are added to, high-toughness high-Mn steel.  
     CONSTITUTION: In high-Mn steel containing 7W40% of Mn, contents of C is reduced to 0.9% or less and O 2  to 0.015% or less, and Si<3%, Cr<10%, and V<5% are added. Or further, at least one of Ni<10%, N<0.3%, Mo<4%, Cu<2%, W<2%, Co<2%, B<0.01% REM<0.5%, Ti<2%, Nb<2%, Zr<2%, Al<2% may be added. From a normal high Mn steel used for crushing rocks or parts therefor, or earth and sand excavator, C is somewhat reduced to prevent carbide from precipitating on grain boundaries. This enhances abrasion resistance to earth and sand. Addition of Cr and V reduces initial abrasion and assists in work-hardening property and thereby improves earth-sand abrasion resistance. Reduced amount of O 2  improves weld padding property. This also reduces oxide impurities so that sand-earth abrasion resistance is improved.
