Patent JP-S5984404-A (JP)
Title: Ac magnet
Inventor: HIROTA TETSUYA
IPC: G01N27/90
Filed: 1982-11-05
Abstract: PURPOSE:To prevent an AC magnet with a laminated core whose opposite poles are facing each other from a damage such as burning or dielectric breakdown by a method wherein an endless coil is provided near the pole at the end of the direction of the laminate and direction of the axis of the coil is identical with that of the laminate so that heat generation near the magnetic pole of the end is suppressed. CONSTITUTION:An AC magnet is composed by winding exciting coils 2 around both legs of a laminated core 1 which is roughly U-shaped. At that time, an endless coil 6 is attached to one end of a tip 1a of each leg which is made wider and the direction of the axis of the endless coil 6 is identical with that of the laminate. With this constitution, flux 4 along the direction of the laminate is suppressed by flux 7, whose direction is opposite to that of the flux 4 and produced by an induced voltage generated in the coil 6 according to the Lenz's law so that the heat generation caused by the eddy current generated by the flux 7 is suppressed. Thus, protection of the AC magnet for magnetic flaw detection, which does not need magnetic field at the end part of the laminate, from the damage caused by the eddy current is realized.

Abstract: PURPOSE:To permit production of a bright tin plated steel plate having excellent paint adhesion and high temp. water resistance by carrying out Ni plating on the surface of a tin plated steel plate then plating a metallic Cr layer and a Cr hydroxide layer further thereon. CONSTITUTION:After a cold rolled steel plate for plating is defatted and washed, tin electroplating is carried out on both surfaces thereof at 1.12-11.3g/ m<2> quantity. The steel plate is heated to temp. higher than the melting temp. of tin to melt the tin and to apply a brightening treatment; thereafter, Ni plating is carried out on the surfaces thereof at 1-20mg/m<2> quantity. Further an electrolytic chromic acid treatment is applied thereon and 10-100mg/m<2> a metallic Cr layer and 5-30mg/m<2> a Cr hydroxide layer as Cr are formed thereon. Since the Cr layer and the Cr hydroxide layer are formed by interposing the Ni layer on the Sn layer, the exfoliation of the Cr layer on the surface of the Sn layer is eliminated by the increased adhesion between the Sn layer and the Ni layer as well as between the Ni layer and the Cr layer, and the tin plated  steel plate for canning having high paint adhesion and high temp. water resistance is obtained.

Abstract: PURPOSE:To enable the fine patterns to be formed by a method wherein electron beams are accelerated in an electron emitting part to be once decelerated before passing deflectors but accelerated again in the part near a specimen surface for increasing the throughput and reducing the forward scattering. CONSTITUTION:An electron gun; a condenser lens 12, a decelerating ing electrode 41a; aperture masks 14, 16, deflectors 23, 22; an accelerating electrode 42b existing between said elements are respectively impressed with V0, V1, V2, V3 (V3=0V fixed). At this time, the electron beams accelerated by V0-V1 in an electron emitting part are once decelerated by V0-V1 to be accelerated again by V2-V3 in the part near a specimen surface. In such a case, the electron beams in the same high brightness as that of a high accelerating voltage device and in the less forward scattering on a specimen surface can be emitted as well as the accelerating voltage is stepped down in the deflecting parts thereby enabling the deflecting regions to be widened. Through these procedures, the title electron beam lithography device capable of forming fine patterns can be realized.

IPC: H04Q9/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To reduce a transfer time of a remote control code and to increase the number of slave stations per master station. SOLUTION: Software processing about entire remote control codes is performed by a common system, and a spare system only sends received data. This system consists of master stations CC1 and CC2 and slave stations SS1 to SS5, and the common system of each slave station SS1 to SS5 performs delay regenerative relay of free tokens TE (a token signal having only a header without the following code) or busy tokens TF (a token signal having the following code). On the other hand, the spare system performs only hardware relay, and this structure of the system shortens about 5msec per place of a spare system in comparison with a conventional method where entire common and spare systems perform delay regenerative relay.

IPC: G06F19/00
Filed: 1994-08-19
Abstract: PURPOSE: To make desirable fixing even in the case of performing printing over consecutive pages of a passbook by setting the fixing setting temperature of the fixing device for each page in reference to the fixing temperature setting table. CONSTITUTION: In reference to the first fixing temperature setting table based on the number of pages, the fixing setting temperatures required for printing the head page 43 and the next page 44 are set. In this case, the fixing setting temperature is set by setting the following voltages: the fixing voltage, the upper limit voltage, and the lower limit voltage required for printing the head page 43 and the next page 44. For this purpose, the first fixing temperature setting table is stored with the fixing setting temperatures suitable for printing in the first page 43 and the second page 44 when these pages are under a two- page spread condition. When a different page is printed, heat capacity is also different. Accordingly the fixing voltage which differs depending on each page is stored.

Title: Magnetic head
Inventor: SATO KAZUHIKO
IPC: G11B5/187
Filed: 1987-08-05
Abstract: PURPOSE:To improve wear resistance and to extend the life of a magnetic head by packing a nonmagnetic member via wear resistant nonmagnetic films into a pair of recesses delineating the width of a magnetic gap. CONSTITUTION:Two lines of the recessed which delineate the length l of the magnetic gap in the transverse direction of a tape are formed to both sides at the top ends of a pair of magnetic half bodies 11, 12 constituting a magnetic head in parallel over the entire surface for contact with the tape. The glass 17 as the nonmagnetic member are packed in the recesses. The wear resistant nonmagnetic films 18 consisting of forsterite or magnesium titanate are interposed between the glass 17 and the wall surfaces of the recesses in which the glass is packed so as to form a part of the surface for contact with the tape. The wear resistance of the part for contact with the tape where the head comes into contact with the tape at a high relative speed is thereby improved by the provision of the wear resistant nonmagnetic film 18. The life of the magnetic head is thus extended and the need for exchanging the head is eliminated for a long period of time.

Title: Air supply passage opening/closing device
Inventor: HAGIWARA TADASHI
IPC: F24F13/15
Filed: 1990-07-24
Abstract: PURPOSE:To perform quiet closing of a damper and to simplify the constitution for regulating a damper position by a method wherein when a damper opened in a way to pivot in the direction of a supply air flow is closed, the damper is made to pivot against a force on which a supply air flow is exerted. CONSTITUTION:When a motor 11 is run and gears R6 and L7 are rotated, dampers R2 and L3 secured on a gear shaft 8 are rotated approximately in a 90 deg. arc in the same direction as a direction P of a supply air flow to open the supply air passage of a body 1. Meanwhile, when a power source is turned OFF, a damper release holding state by means of the motor 11 is released, the positions of the dampers R2 and L3 are returned to a stopper 12 by means of a return bus 9. In this case, since the dampers R2 and L3 are made to pivot against a force on which a supply air flow is exerted, pivoting operation is brought into a slow state. Thus, the dampers R2 and L3 prevent the generation of pleasant noise due to an impact on the stopper 12, whereby there is no need to solidly form the stopper 12 and firmly mount the stopper.
