Title: Magnetic recording medium and production thereof
Inventor: SUGITA RYUJI
IPC: G11B5/73
Filed: 1990-04-05
Abstract: PURPOSE:To obtain isolated reproducing waveforms having less sub-pulses by forming a 1st magnetic layer to the film thickness larger than the total film thickness of 2nd and 3rd magnetic layer to make the quantities of magnetic flux flowing into a magnetic head from both magnetic layers nearly equal. CONSTITUTION:A high-polymer substrate 1 is made to travel toward an arrow 18 and the magnetic layers are formed thereon. Then, the incident angle of evaporated particles on the substrate changes from theta1 to theta2 as the film grows at the time when the 1st magnetic layer is formed in the part of an aperture 15. The axis of easy magnetization inclines to the normal of the film plane and the medium having the isolated reproducing waveforms is obtd. if the inci dent angle of the evaporated atoms on the substrate is made to, for example, >=10 deg. and <=70 deg. at the time of this film formation. The quantities of the mag netic flux flowing from these two magnetic layers to a magnetic head are approximately equaled by forming the 1st magnetic layer to the film thickness larger than the total film thickness of the 2nd and 3rd magnetic layers, by which the isolated reproducing waveforms having the less sub-pulses are obtd.

Title: Method of evacuating heat-treatment furnace, and heat-treatment furnace
Inventor: FUJINAGA KIYOO
IPC: C23C16/44
Filed: 1994-04-28
Abstract: PURPOSE:To prevent particles from adhering to a wafer and to shorten the treatment time required for an evacuation operation. CONSTITUTION:Since three exhaust ports 3 are formed near contact parts of a wafer 7 with a boat 6, aerial currents 10 on the surface of the wafer 7 in a vacuum evacuation operation inside a reaction tube can be generated to be nearly parallel with the surface of the wafer 7 and in a direction advancing to the outside of the wafer 7 from the inside of the wafer 7. Many particles existing near the contact parts of the wafer 7 with the boat 6 are scattered to the outside of the wafer 7 together with the aerial currents 10, they are not scattered to the inside of the wafer 7, and it is possible to prevent them from adhering to the surface of the wafer 7. In addition, since it is not required to divide an evacuation speed into two stages as measures taken against the particles in conventional cases and to make the evacuation rate slow at first (slow pumping), the treatment time required for an evacuation operation can be shortened.

Title: Chip type piezoelectric vibrator
Inventor: SUMIDA MANABU
IPC: H03H9/02
Filed: 1986-04-18
Abstract: PURPOSE:To set a piezoelectric resonator at a proper position and also to prevent a conductive adhesive from flowing into a vibrating part owing to a capillary phenomenon, by forming banks to the inner walls at both ends of a cylindrical insulated case to support a piezoelectric vibrator. CONSTITUTION:As shown in the diagrams, the thick electrodes 14 are formed at both ends of a cylindrical and hollow insulated case 10 so that they enclosed the corners 10a of a cap 12. The thickness of the electride 14 set at such value that prevents a case where a conductive adhesive 22 moves up by a capillary phenomenon produced between the case 10 and a piezoelectric resonator 16. In such a way, the electrodes 14 are formed and the resonator 16 is put into the case 10. Thus both ends of the resonator 16 are supported by those electrodes 14. Then the cap 12 is set. In this case, a space is secured between the surface of the resonator 16 and the inner wall of the hollow part of the case 10. Therefore the adhesive never flows into the vibrating part.

Title: Gradient magnetic field coil used in magnetic field generator for nuclear magnetic resonance imaging
Inventor: IINUMA TOSHIYA
IPC: H01F6/00
Filed: 1989-04-11
Abstract: PURPOSE:To disperse the eddy current generated in the metal, especially, the magnetic pole in the vicinity of a gradient magnetic field coil, to improve the linearity of phase encoding quantity and to also improve the ghost appearing in the encoding direction of an image by expanding the interval of the turns forming the gradient magnetic field coil. CONSTITUTION:A pair of the upper and lower circular coils 1a generating a gradient magnetic field Gz arranged to the magnetic pole 4 of a gradient magnetic field coil are wound so that the mutual interval between the conductors constituting adjacent turns is expanded at every (n) turn (n>=1). By expanding the mutual interval between the conductors forming the gradient magnetic field coil, the current flowing to the gradient magnetic field coil 1 is not gathered but dispersed and, therefore, the eddy current flowing to the metal, especially, the magnetic pole 4 in the vicinity of the gradient magnetic field coil is dispersed. When the interval D is too wide, the component of Z2 or more of the gradient magnetic field Gz increases and linearity is damaged and, therefore, it is necessary to determine the internal D within a range not damaging linearity. As a result of actual adaptation, sufficient effect is developed in D=about 15mm.

Title: Thrust bearing
Inventor: WASHIDA AKIRA
IPC: F16C32/06
Filed: 1978-07-26
Abstract: PURPOSE: To increase a loading capacity of a thrust bearing and to provide a vibration-absorbing and a vibration-proof properties, by arranging a great many bearing strips, which have a bearing surface, on support boards made of a flexible material and by providing a space at a portion where the bearing strip is in contact with the support board.  
     CONSTITUTION: When a shaft 1 in the direction A, a fluid comes in the space formed between a bearing surface 7 and an end surface 2, and presses downward a bearing strip 8. This causes the back part (a lower part) of the bearing surface 7 inclines. In consequence, the fluid is further pressed into the space formed between the bearing surface 7 and the end surface 2, and an allowable PV value increases as a result of the pressure of a fluid film increasing sharply owing to the wedge action. In the title thrust bearing, each bearing strip is supported so that the space 11 is provided by a support board 6 made of a flexible material and having a contact part 10, and as a result shock is absorbed. Furthermore, since each bearing strip 8 comes in uniform contact with the end surface 2, the load is uniformly supported and a load capacity is maximized. A vibration absorbing property and a vibration-proof property can thus be improved.
