Title: Syringe for animal and needle for animal
Inventor: YAMAKAWA KIYOYASU
IPC: A61D7/00
Filed: 1996-04-06
Abstract: PROBLEM TO BE SOLVED: To prevent a needle from being broken or to make the needle hard to be broken by fitting a stopper cylinder at the top end of cylinder of a syringe to surround the needle and protruding the needle from the top end of this stopper cylinder. SOLUTION: At the top end of a cylinder 1, a bolt-shaped metal fixture 6 is screwed for fitting a needle 5 and at that head part, the needle 5 is attachably and detachably fitted. Concerning a stopper cylinder 7, the male screw part of the bolt-shaped metal fixture 6 is passed through a hole formed on that bottom part, screwed and fixed to the top end of the cylinder 1. Namely, the stopper cylinder 7 is fitted to the top end of the cylinder 1 by the bolt- shaped metal fixture 6 for fitting the needle. Thus, since the stopper cylinder 7 gets press-contact with the body surface of animal, force to be operated upon the root of the needle 5 is decreased. Further, when the needle 5 is abutted to the inner periphery of top end of the stopper cylinder 7, force is not operated upon the root of the needle 5 any more, and the needle is made much harder to be broken.

Title: Cooling method for steel hoop in continuous annealing apparatus
Inventor: FUKUOKA YOSHIKAZU
IPC: C21D1/26
Filed: 1979-08-31
Abstract: PURPOSE:To regulate the temp. of a steel hoop rapidly and accurately so as to cool it thereby improving the quality of products, by contacting the steel hoop with metallic rotators, which are internally cooled with water, in order to cool the hoop, and making changeable the contacting arc length of the rotators with the hoop. CONSTITUTION:Temp. TE of a steel hoop 23, which has been heated in a heating furnace and a soaking furnace, at the inlet of quenching zone is measured with a sheet thermometer 21c for hoop. The temp. TE is compared with desired temp. TE0 by a regulator 29 for hoop temp., and the deviation is reduced to zero either by changing the set temp. for the heating furnace and the soaking furnace, or by changing the line speed. The temp. TD of the hoop at the outlet of the metallic rotator 22 is measured by a sheet thermometer 21d arranged at the outlet, and the temp. TD is compared with the desired temp. TDO by a regulator 29. If deviation is present, the deviation TD-TD0 is reduced to zero by feeding back, and a motors 26, gears 25, screws 24 are rotated by a mechanism 30 for changing the contacting length so as to change the positions of rotators 22, which are so set that their positions are changeable, thereby changing the contacting length. The cooling after overaging is performed in the same way.

Title: Production of two-layered magneto-optical recording medium subjected to initialization
Inventor: IIDA MASAYO
IPC: G11B11/105
Filed: 1990-04-26
Abstract: PURPOSE:To shorten a time for initialization processing by initializing a low-coercive force layer after the formation of the film thereof, then forming the film of a high- coercive force layer. CONSTITUTION:A glass substrate 1 is set on a substrate holder 2 of a sputtering device of a process for producing a magneto-optical recording medium consisting of the two-layered films of the low-coercive force layer and the high-coercive force layer exchange-bonded therewith. After the inside of the device is evacuated to a vacuum, the films of a 1st protective layer and the low-coercive force layer are formed on the substrate 1. A permanent magnet 3 is moved without breaking the vacuum and the substrate 1 is rotated >=1 turns in this state and is subjected to the initialization processing by which the directions of magnetization are unified. The permanent magnet 3 is thereafter returned to the home position and further the film of the high-coercive force layer is immediately formed without breaking the vacuum. The directions of the magnetization of the high-coercive force layer are unified by the effect of the exchange bond from the initialized low-coercive force layer and are thereby initialized. The relatively smaller magnetic fields for the initialization are necessitated and since the initialization is executed at one time, the time for the initialization processing is shortened.

IPC: G11B20/10
Filed: 1984-05-31
Abstract: PURPOSE:To effectively prevent interference between codes, by adding a square wave of a width proportional to the inversional width of a recording electric current to the rising point of the recording current and, at the same time, another square wave of a width proportional to the falling width of the recording current to the falling point of the recording current. CONSTITUTION:A count value latched by a latch circuit 9 addresses a ROM10 at the timing shown by the waveform G and the ROM10 outputs parallel data of a scale proportional to the address, namely, the count value. The parallel data are converted into serial data by a parallel-serial converting circuit 11 and become a square wave having a width proportional to count values of counters 1 and 2, namely proportional to the inversional interval of a recording electric current as shown by a waveform H. The square wave is supplied to an adder/subtractor circuit 13 after an appropriate quantity is attenuated by an attenuator 12. By making the width of a square wave superposed upon the recording current proportional to the inversional width, the rising end and falling end and a position behind the ends, where magnetization inversion is produced in the opposite direction, can be standardized with respect to the inversional width.

Filed: 1985-05-24
Abstract: PURPOSE:To reduce waveform asymmetry which occurs at the time of recording by canceling a magnetic field which leaks to a recording/reproducing head from an erasing head. CONSTITUTION:A coil is wound by several turns to a recording/reproducing back bar 11, it goes to an additional coil 13, and this additional coil winding is connected in series to a canceling coil winding 10. When a canceling current flows to canceling coil at recording, the current flows by the same timing to the additional coil, as well. A magnetic field which is generated by a canceling current and leaks to a recording/reproducing head from a canceling head, and a magnetic field which turns around a recording/reproducing magnetic core by the additional coil cancel each other in a magnetic gap part of the recording/ reproducing head. In such a way, at the time of recording, no bias is applied to a recording magnetic field, and a waveform asymmetry which occurs at the time recording is reduced.
