Title: Magnetic thin film head
Inventor: OOTSUKA KOUJI
IPC: G11B5/39
Filed: 1982-11-09
Abstract: PURPOSE:To make the gap in an MR thin film head narrow and to increase the resolving power by providing a two-layered structure consisting of a relatively thick under layer having a tapered end and a relatively thin upper layer to a lead wire for supplying electric current to an element having a magneto-resistance effect so as to reduce difference in level. CONSTITUTION:The 1st electrically conductive layer 12 of Al-Cu is formed on the whole surface. A resist film having a prescribed pattern is formed on the layer 12, and the layer 12 is etched. Since the layer 12 is exposed to plasma beforehand, it has low adhesive strength to the resist film, so an end of the layer 12 is tapered. Only the 2nd electrically conductive layer 13 is present at the lead part under an upper magnetic shielding layer 15, and the layer 12 is not present, so difference in level is reduced, and even when an insulating layer 14 is made thin, insulation can be kept stably. Most of the lead part is a thick two-layered film consisting of the 1st under layer 12 and the 2nd upper layer 13, so the lead part has a low resistance value.

Title: System and device for floating point multiplication system
Inventor: OKAMOTO FUYUKI
IPC: G06F7/487
Filed: 1989-07-28
Abstract: PURPOSE:To suppress the arithmetic of a number which is not normalized and perform floating point multiplication by only inspecting the most significant digit of the product of a mantissa part by a normalizing decoder and shortening a scanning time. CONSTITUTION:When the product of a multiplicand 2<3>X0.01110 and a multiplier 2<4>X0.00011 is found, a multiplier 10 calculates the product of the mantissa parts of the multiplicand 1 and multiplier 2 to obtain 0.000010101. Digit position decoders 7 and 8 add the number of leading 0s of the multiplicand, i.e. 0 and the number of leading 0s of the multiplier, i.e. 3 to obtain the sum 1+3=4, which is used as a shift digit quantity for left shifting to obtain 0.10101. The sum 4 is obtained by subtracting the sum 4 of the numbers of leading 0s from the sum 3+4=7 of the exponent parts to obtain an answer 2<3>X(0.10101), which is equal to the answer found by normalizing the multiplicand and multiplier. Here, the most significant digit is decided and only when it is 0, the number is shifted left by one digit. The arithmetic time is shortened since leading 0s need not be detected unlike before by scanning all digits of the product of the mantissa parts for normalization.

Title: Manufacture of cylindrical alkaline secondary battery
Inventor: NAGAURA TORU
IPC: H01M2/02
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To stuff more active material into a battery container than a conventional one by improving a battery manufacturing method by means of diameter shrinking and thereby realize high capacity of a cylindrical battery. SOLUTION: An electrode element 10 is brought into a condition, in which it is unable to move vertically in a battery can 4 by catching and fixing it by a seam part 5 and a can bottom at its upper and lower parts before diameter shrinking. Thereby, the electrode element 10 will not be pushed up toward the opening of the battery can, even when the outside diameter of the bottom of the battery can 4 is partly shrunk in the succeeding diameter shrinking process, so that no clearance is produced between the bottom of the battery can and the electrode element 10, even after the diameter shrinking process has been completed. The extension of the battery can caused by the diameter shrinking of the battery can 4 is used to secure an appropriate clearance between a sealing lid and the electrode element 10.  Therefore, because there is not negative factor due to wasteful space produced from the extension of the battery can 4 by the diameter shrinking, the advantage of the manufacturing method by means of diameter shrinking is utilized maximally.

Title: Semiconductor memory cell
Inventor: TERADA KAZUO
IPC: G11C11/34
Filed: 1985-09-06
Abstract: PURPOSE:To execute a stable reading action even when a part of the supplying voltage is reduced accompanying the miniaturizing operation by providing a variable capacity element in which one side electrode is connected to the second energizing electrode of the transistor and other side electrode is connected to the read only word line larger than the line where the amplitude of the supplying voltage is supplied to a bit line and a word line. CONSTITUTION:The threshold voltage of MOSFET 11 is 0.5V, a variable capacity element 12 shows the larger capacity value when the electric potential of a memory node 19 side is higher than the electric potential of a read only word line 16 side by 0.5V or above, and the element shows the very small capacity value at the time except for it. At the time of the reading action, the read only word line 16 is changed from 0V to 5V, and at such a time, the electric potential of the memory node 19 of a '1' storing memory cell rises from about 2V to at least about 5V by the linking of the capacity. On the other hand, the electric potential of the memory node 19 of the '0' storing memory cell at such a time is about 0V as it is and the capacity value of the variable capacity element 12 is small as it is.

IPC: B21C31/00
Filed: 1985-09-06
Abstract: PURPOSE:To directly measure the mutual eccentricity of the center at the outlet and inlet sides of a stem and container by fitting a center measuring panel on the inner face of the container inlet port and outlet port and by pressing the center indicating member engaged with the stem tip thereto. CONSTITUTION:The center indicating member 4 composed of a center 4a, sleeve 4b, etc. is fitted to the tip part of a stem 3. The center measuring panels 5, 6 that the center 5a, 6c are clarified are provided attachably and detachably on the inner face of the inlet port and outlet port of a container as well. In case of the measurement of the eccentricity, the measuring panel 6 is first fitted to the container inlet port and after pressing the center indicating member 4 fitted to the stem 3 thereto, the eccentricity is found by comparing the marked position and the center 5a by removing the measuring panel 5. It is similarly measured with the measuring panel 6 at the outlet port side as wel. Consequently the eccentricity mutual at the center at the outlet and inlet sides of the stem 3 and container 10 can directly be measured and with the correction thereof with the wall deviation of the extrusion steel pipe can be reduced.

Title: Image transferring device
Inventor: IZUMI TAKAO
IPC: G03G15/16
Filed: 1989-07-31
Abstract: PURPOSE:To prevent generation of soiling of the back of the transfer material and transfer uneveness even when continually used for a prolonged period of time, by making the difference between work function PHIT of developer and work function PHIR of a surface material of a transfer member under 4.0eV. CONSTITUTION:When toner and the transfer member come into contact, electrical charge carrier travels across a contact surface boundary from the higher electrochemical potential side to the lower side. As the result, two objects are electrified to opposite signs with the equivalent electrical charge quantity, and the difference in contact potential at this time Vc is shown by formula 1. When two objects are separated, the carrier flows backward within the range where the electrical charge carrier can exceed a potential barrier of the boundary, and the electrical charge remaining in the object is observed as electrifying electric charge. The difference between the work functions of the toner and the transfer member ¦PHIT-PHIR¦ is made to be below 4.0eV. Thus, the toner can be prevented from adhering to the transfer member.

Title: Semiconductor laser
Inventor: AZUMA TOSHIO
IPC: H01S5/00
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To reduce the optical loss by forming a tapered waveguide structure where the thickness of active layer and isolated confinement layer decreases toward the emission edge but the thickness of barrier layer is constant thereby suppressing the coupling between quantum welts in tapered waveguide. SOLUTION: A tapered waveguide 12 has a structure where the thickness of an active layer 5 and isolated confinement SCH layer 6, 3 sandwiching the active layer decreases gradually toward the emission edge 13 but the thickness of a barrier layer 4 is invariant. Since the tapered waveguide 12 includes a barrier layer of invariant thickness, coupling does not take place between the quantum wells. Consequently, only the band gap is enlarged due to thinner quantum well active layer and the wavelength is shortened at the absorption end. This structure prevents undue increase of absorption loss due to integration of tapered waveguide.

Title: Racket
Inventor: OHARA TOSHIYUKI
IPC: A63B102/02
Filed: 1987-08-07
Abstract: PURPOSE: To compromise between the swinging easiness and the ball hitting speed by providing a racket frame with a balancer which can freely move between a position near the grip and a position near the racket, and urging means for urging the balancer toward the position near the grip. CONSTITUTION: A balancer 4 and a spring 4 as an urging means are accommodated in a cylinder 5 attached to a frame 1, and in a normal condition, since the balancer 3 is located at a position near a grip G by the urging force of the spring 4, a large force is not required at a start of swinging. Further, the urging force of the spring 4 is set to be greater than the weight of the balancer 3, and upon hitting, the spring expands since a centrifugal force greater than the urging force of the spring 4 is applied in a direction in which the head H of the racket is advanced. Thus, the balancer 3 is moved toward the head H so that the gravitational center of the racket appoaches the head H, and accordingly, the ball hitting speed can be enhanced.  Thus, it is possible to reduce the inertial moment at a start of swinging, and to increase the inertial moment at the instant of hitting of a ball, thereby it is possible to compromise between the hitting easiness and the ball hitting speed.
