Title: Manufacture of thermoplastic resin film
Inventor: SHIMIZU HIDENORI
IPC: B29C55/08
Filed: 1990-06-29
Abstract: PURPOSE:To prevent adhesion at a holding part, by a method wherein a nonadhesive resin layer having a softening point higher than that of a heat bonding layer on a part to be held substantially is laminated to the heat bonding layer laminated evenly extending over the whole width. CONSTITUTION:A nonadhesive layer 4 having a fixed width is laminated to a base layer 2 and heat bonding layer 3 which are laminated evenly, in a form where both end parts of a widthwise direction are coated with the heat bonding layer 3. Polyethylene terephthalate and polyvinyl chloride are available as resin of the base layer 2. Then polyester, polypropylene and polyamide are available as resin of the heat bonding layer 3. Sine it is necessary that the nonadhesive layer 4 is of a resin whose substantial melt softening point is higher than a surface temperature of a tenter clip at the time of thermal fixation after lateral stretching, even the same kind of resin as the base layer 2 may be good or even the other resin having a high softening point may be good. However, it is preferable that the nonadhesive layer 4 is of the same raw materials as those of the base layer 2 to make reuse of cutting layer to be obtained through recovery by cutting both end parts after stretching and thermal fixation.

Abstract: PURPOSE:To reduce the number of manufacturing processes of a thin-film magnetic head so as to prevent the magnetic head chip of the head from being damaged by successively forming a protective layer, lower magnetic layer, gap layer, 1st insulating layer, coil pattern layer, 2nd insulating layer, and 2nd magnetic layer on one surface of a base plate and fixing the magnetic head thus produced to the side face of a nonmagnetic substance of a slider member in a facing state. CONSTITUTION:Plural blocks for constructing magnetic head chips by a thin-film technology are set on a light-transmissive insulating nonmagnetic base plate 50 of glass, etc., and conductors 51 which are used as terminals of head coils is embedded in each through hole of the blocks. Then the coil terminal of the magnetic head section 52 formed in each block is connected with the conductors 52 and one magnetic head chip 55 is cut off. The chip 55 is then fitted to the side face of the end section of a slider member 60. The side face is formed of a nonmagnetic material and the chip 55 is firmly stuck to the side face with a bonding agent so that the chip 55 can face the side face. Thus the number of manufacturing processes is reduced and breakage of the magnetic head chip can be prevented.

Filed: 1993-07-14
Abstract: PURPOSE:To provide an image of a high resolution without causing deterioration of an S/N ratio by applying an inclined magnetic field in the frequency direction of a desired size and a different polarity immediately before each frequency encoding in such a way that timings of the frequency encoding and echo signal measuring are deflected from each other. CONSTITUTION:In an MRI device, after spinning of a testee is excited by a 90 deg. pulse, 180 deg. pulses are applied repeatedly to obtain echo signals, and phase encoding, of a different polarity, is applied with a different value for each 180 deg. pulse before and after frequency encoding for each echo signal. In this case, an inclined magnetic field of the same size and different polarity is applied immediately after every frequency encoding in such a way that timings of frequency encoding and echo signal measuring are deflected from each other. A time t1 at a center of the inclined magnetic field is set to be a center time in the frequency encode direction, setting a peak of the echo signal at the time t1 of the inclined magnetic field when its surface becomes similar to that of the inclined magnetic field, thereby asymmetric sampling is enabled.

Abstract: PURPOSE:To simplify the manufacture, to reduce the cost and to improve the S/N ratio, by using a board provided with an input plane projected as checkers and an input pen having a magnetic anisotropy laminated with high permeability thin plates. CONSTITUTION:With a drive line Xa 203 driven, a voltage E1 is induced in a sense wire Ya 204 with a magnetic flux passing through a direction in parallel with a laminated layer of an input pen 107 and generated to a magnetic path to a projection B310 from a projection A309. Similarly, a voltage E2 is induced in the sense wire Ya 204 with a magnetic path reaching a projection D312 from the projection orthogonal to the laminated layer of the input pen 107. The voltages E1, E2 have opposite polarity. Since the construction of the input pen 107 is magnetically anisotropic, the magnetic reluctance in parallel with the laiminated layer is small and that in orthogonal direction is large, the directivity is produced for magnetic coupling, the voltage E1 can considerably be taken larger than the voltage E2, allowing to detect coordinates X3 and Y3.

Filed: 1982-10-01
Abstract: PURPOSE:To cut a pipe simply without damaging the pipe in cutting a pipe using an electromagnetic forming device and dies having sharp shoulder parts by setting the quantity of electric energy within the range in which stress necessary for cutting is generated. CONSTITUTION:A pipe 2 is fitted to a cutting coil 1 on a coil stand 5. At the same time, a pair of dies 6a, 6b are arranged at the outside of the pipe 2 through a spacer 8. These dies 6a, 6b have sharp shoulder parts 7a, 7b along the cutting line of the pipe 2 on inner rims of opposing faces, and the distance between cutting lines can be determined by changing the distance (l) between opposing dies. The pipe is cut by the same principle with electromagnetic forming. When electric energy accumulated in a capacitor C is supplied to the cutting coil 1 which acts as a primary coil, the pipe 2 becomes a secondary coil and induction current is generated. Repulsive force is generated between the coil 1 and pipe 2 corresponding to the change of magnetic field. The cutting part of the pipe 2 is bulged out between the pair of dies 6a, 6b, and the pipe 2 is cut.

Abstract: PURPOSE:To attain the direct connection between a tablet and a personal computer by counting the counter control signal in a counter read inhibiting period, reading the counted value in a counter read permitting period via a CPU and initializing a counter. CONSTITUTION:A tablet 10 outputs the counter control signals to an image processor 20 only in a counter read inhibiting period and a counter 22 counts the counter control signals. A counter state discriminating circuit 23 receives a counter read control signal from the tablet 10 and discriminates a read permitting period or a read inhibiting period of the counter 22 based on the counter read control signal. A period interruption generating circuit 24 outputs a signal to periodically carry out the interruption for initialization of the value of the counter 22 after a CPU 21 reads the value of the counter 22 in the counter read permitting period. Thus the CPU 21 reads the value of the counter 22 in a counter read permitting period and initializes the counter 22. In such a constitution, the tablet 10 can be directly connected to a personal computer.

Title: Sealed lead-acid battery
Inventor: KAWAI KATSUYOSHI
IPC: H01M10/16
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To suppress upward elongation of electric collectors of respective electrode plates and prevent separation of active materials from the electric collectors and rupture of the electric collectors by installing an acid resistant frame, which applies pressure to respective electrode plates composing a unit of electrodes, in a space between the unit of electrodes and a battery jar lid. SOLUTION: In a sealed lead-acid battery, an acid resistant frame 3 to apply pressure to respective electrode plates constituting a unit 1 of electrode plates is installed in a space between the unit 1 of electrode plates and a battery jar lid 4. Consequently, the upper ends of respective plates are pushed by the acid resistant frame 3 and the upward elongation of electric collectors of respective electrode plates can be suppressed. As a result, separation of electrode active materials from the electric collectors due to the upward elongation of the electric collectors and rupture of the electric collectors can be prevented, so that taking out of energy of the battery can be carried out without a trouble.  Moreover, since the electric collectors are not extended upward over a retainer, short circuit between electrodes with different polarity, which generally occurs above the retainer can be avoided and a risk of firing can be also avoided.
