Title: Detection of magnetization characteristic for magnetic thin film
Inventor: FUJITA HIROTO
IPC: G01R33/14
Filed: 1991-01-17
Abstract: PURPOSE:To exactly detect a thin film by impressing a low frequency signal on the primary coil of a differential magnetic head while a medium is brought into contact with, approached closely to the gap part of the head so as to shift a magnetic field and generating small differential output in a secondary coil when the magnetization characteristic of the magnetic medium having the magnetic thin film on both surfaces is detected. CONSTITUTION:The primary coils 31 and 33 and the secondary coils 32 and 34 are wound to cores 30 where a gap 1A is provided for a detection-side and a gap 1B for a non-detection-side and they are set to be the differential magnetic head 1. When the magnetization characteristic of the magnetic medium having the magnetic thin film 40 on the both surfaces is detected, the low frequency signal is impressed on the coil 31 while the medium is brought into contact with, is approached closely to the gap 1A so as to shift the magnetic filed by the low frequency signal. Thus, differential output voltage generated in the coils 32 and 34 is amplified in an amplifier 37 and it is measured. Then, influence owing to the other thin film 40, which is included in said value, is reduced so that it can be ignored by operation. Then, the characteristic of the thin film 40 on one surface is detected based on subsequently obtained data.

Title: Nonaqueous electrolyte battery
Inventor: SUZUKI SHINTAROU
IPC: H01M50/40
Filed: 1983-02-04
Abstract: PURPOSE:To provide a nonaqueous electrolyte battery with a high operation voltage and a great discharge capacity by stacking a plural number of separators within the range that the internal resistance does not becomes excessively high. CONSTITUTION:When nonwoven cloth with a weight per m<2> of below 15g/m<2> is used as a separator 5 for separating a positive and a negative electrode 3 and 4, it is necessary to stack not less than five pieces in order to prevent any internal short circuits during electric discharge. Therefore use of such nonwoven cloth as above is not appropriate since much trouble is required in separator manufacturing. As to a separator made of nonwoven cloth with a weight per m<2> of 30- 50g/m<2>, use of only one piece causes a possibility of internal short circuits, and use of two or more pieces results in an excessively high internal resistance and a discharge characteristic which is similar to that obtained when one piece of the conventional nonwoven cloth with a weight per m<2> of 50g/m<2> is used. Accordingly it is necessary to select the number of pieces of nonwoven cloth with a weight per m<2> of 15-30g/m<2> so that the internal resistance does not become excessively high.

Title: Liquid crystal device
Inventor: KAWAKAMI TATSURO
IPC: G09F9/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent a defect in the orientation of a liquid crystal cell due to a shock by sticking a shock-resisting member which suppresses strain of a liquid crystal element due to a shock transmitted through a frame and a buffer material on at least one of the top and reverse surface of a liquid crystal element. SOLUTION: The shock/resisting plate 8 is a shock-resisting member which suppresses the strain of the liquid crystal cell 4 due to the shock transmitted through the frame and buffer plate and a plate material formed of a material with a high modulus of in-surface tensile elasticity. Then shock-resisting plate 8 is stuck where the liquid crystal cell 4 has the largest strain quantity at the time of a shock, i.e., nearby the fixation position of the liquid crystal cell 4. And the material of the shock-resisting plate 8, iron is selected which has a >=150,000MPa modulus of tensile elasticity.  The size of the shock-resisting plate 8 is so determined that it can be put in an upper and a lower frame and covered with them; and the shock-resisting plate 8 is thus covered with the upper and lower frames to prevent the shock-resisting plate 8 formed of iron from covering the visual area of the liquid crystal device.

Abstract: PURPOSE:To prevent the disorder of the welding wire at the time of transit by covering and packing a peripheral part of the welding wire wound on a synthetic resin spool with a heat shrinkage film having the thickness and width of specified dimensions with the specified heat shrinkage factor. CONSTITUTION:The welding wire 6 is wound on the spool 2. This spool 2 is covered with the heat shrinkage film 1, heated, shrunk and packed. The heat shrinkage film 1 has the heat shrinkage factor of 5-20% in the widthwise direction of the spool 2 and that of 50-70% in the circumferential direction of the spool 2 and has the thickness of 60-150mum and the width of the (width of the spool 2+(50-150))mm. The thickness is made to dimensions which are not damaged in transit and besides, economic dimensions. When the width is made to dimensions less than the (spool 2 width+50)mm, the area to cover a flange 5 is insufficient and it is dislocated with the slight external pressure. The adhesion of the spool 2 to the flange 5 is satisfactory and the perfect rust prevension can be carried out.

Abstract: PURPOSE:To accumulate a molten resin in front of a screw at a high speed by arranging a resin detector detecting the molten resin to the leading end part of a heating cylinder and sucking the screw backwardly before rotating the same without applying back pressure thereto to move the resin forward. CONSTITUTION:At the time of injection molding, at first, a screw 12 is sucked backwardly by a suck-back actuator 17 while the output of a position detector 22 is monitored to be moved to a first set position and, next, after the suck-back of the screw 12 is stopped, the screw 12 is rotated at a high speed by a screw rotating actuator 14 and the resin from a hopper 20 is melted in a heating cylinder 11 to be moved forward. When the actual value detected by the resin pressure detector 24 provided to the leading end of the heating cylinder 11 reaches a set value, the screw 12 is rotated at a low speed. When the screw 12 reaches the second set position behind the first set position, the rotation of the screw 12 is stopped. The screw 12 is stopped when it is sucked back to a third set position to complete weighing.

Title: Improving method for residual stress of steel pipe
Inventor: TANAKA SHINJI
IPC: B21D31/00
Filed: 1979-02-19
Abstract: PURPOSE: To leave the compression stress in another plane, by giving a mechanical load to the steel pipe in order to cause a local deformation, and then, by releasing this load.  
     CONSTITUTION: The pipe 3 is caught by pushing from both sides with the guides 2, 2, installed in the restraint frame work 1, in order to prevent the collapsing deformation owing to the mechanical load. A load P is impressed on the pipe 3 by the roller or steel balls 4, 4, in the direction perpendicular to the line connecting the guides 2, 2. The pipe 3 causes a local deformation and generates a strain δ, the tensile stress in the inner surface 3a, and the compression stress in the outer surface 3b of the pipe 3. By adjusting the load so as to make the tensile stress generated in the inner surface 3a of the pipe 3 to be larger than the yield strength of the material, the inner surface 3a yields and causes plastic deformtaion. If the load is released from this condition, since the deformed part of the pipe 3 is restrained by surroundings, the stress of inner surface changes into the compression stress and the stress of outer surface changes into the tensile stress, and both remain as they are. By rotating the pipe 3 under the load, the inner surface successively causes the tensile yield with successive turnover of the loading point, and the compression stress remains in the inner surface according to release of the load with the rotation.
