Title: Lead-acid battery
Inventor: MUKASA TOMONORI
IPC: H01M4/14
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To maintain a stable battery performance over a long term by using a negative electrode activation material containing fatty acid added within a specific range, and specifying the added fatty acid as stearic acid or the salt thereof. SOLUTION: A drop in the discharge capacity of high efficiency particularly increases according to an increase in the amount of added fatty acid and greatly increases, when the added amount exceeds 2%. Thus, the added amount is kept at 1% or less. A battery added with 0.05% or more of fatty acid loses little amount of liquid, showing an excellent liquid losing characteristic. These results show that the added amount of fatty acid is preferably 0.05% to 1%. The liquid losing characteristic is improved because hydrogen generating reaction is suppressed during overcharging by forming a fatty acid film on an active material surface, thereby raising hydrogen overvoltage and reducing a charge current for constant voltage charge. The fatty acid to be used is zinc stearate and higher fatty acid hardly dissolving into dilute sulfuric acid is preferable as the fatty acid.  Particularly, stearic acid and the salt thereof are preferable.

Title: Peripheral interrupter for computer system
Inventor: NIKORASU TSUITSUKU
IPC: G06F13/24
Filed: 1988-05-20
Abstract: PURPOSE: To increase the number of supportable peripheral devices by installing a single interruption signal line between plural peripheral devices. CONSTITUTION: A circuitry is set between a single interruption signal line 102 and each peripheral device 101-1 to 101-N connected to this line. This circuitry involves a first part to transit from a first voltage level to a second voltage level according to an interruption signal pulse received from joint peripheral devices. This second voltage level is kept until a clear interruption signal is added to this circuit after this and the second part of the circuitry speedily returns the interruption signal line to the first voltage level in response to this clear interruption signal. This first voltage level clears the interruption signal line. Thus, an interruption signal is converted by another peripheral device. Thereby, supportable peripheral devices are increased.

Title: Rolling method for flanged shapes
Inventor: INAGAKI AKIRA
IPC: B21B1/088
Filed: 1986-05-30
Abstract: PURPOSE:To produce many kinds of shapes of different kinds and sizes with good productivity by disposing a rolling mill having specifically shaped cross helical rolls between intermediate rolling and finish rolling at the time of rolling the shapes by rough rolling, intermediate rolling and finish rolling. CONSTITUTION:A beam blank 4 from a break down mill 1 is molded to the sectional shape of an intermediate material 25 by an intermediate universal rolling mil l 2. The intermediate material 25 is then rolled by a cross helical roll type rolling mill 14. Two pieces each of the upper and lower cross helical rolls 15, 15',16, 16' of this rolling mill contact the flanges of a material 17 to be rolled and roll down the web part in proixmity to the flanges of the material to be rolled while the roll shafts maintain the angle thetaH in the rolling direction within the horizontal plane and thetaV with the horizontal shafts, thereby fluidizing the material of the rolled down part in the transverse direction and expanding the web in the transverse direction. The size of expanding the width in the transverse direction is basically determined by setting the angles thetaH, thetaV and the cross helical roll gap for each of the product sizes. The material is successively rolled by the finishing mill which permits the change of the barrel width of the horizontal rolls in the axial central direction.

IPC: G11B5/187
Filed: 1984-06-18
Abstract: PURPOSE:To prevent the leak of magnetic flux and to eliminate a false gap action by eliminating a work degenerated layer of a ferrite in the joint boundary part between the ferrite and a magnetic alloy film of a high saturation magnetic flux density, which is formed on the ferrite, to form a magnetic gap. CONSTITUTION:Flat parts 21 narrower than a prescribed track width tw and V-shaped grooves 22 are provided on the joint surface of each of two core part pieces 20 and 20' consisting of a high-permeability ferrite, and a winding groove 23 is formed in one core part piece 20', and a magnetic alloy film 24 of a high saturation magnetic flux density is formed on the joint surface of each part piece. After nonmagnetic packing layers 26 consisting of a high-melting point glass or the like are formed in grooves 22, and both part pieces 20 and 20' are so assembled that gaps 27 are constituted while projecting to hill shapes, thus obtaining magnetic heads. In this assembling, alloy films 24 are formed after work degenerated layers, which are generated when grooves 22 are formed, on surfaces of grooves 22 of core pieces 20 and 20' are removed by etching with an aq. solution of a phosphoric acid. An alloy whose magnetic permeability is equal to or higher than that of ferrite part pieces 20 and 20' is used as materials of films 24. Thus, an excellent magnetic head is obtained where false gaps are not generated in joint parts parallel with the gap 27 though different kinds of magnetic materials are joined to each other.

Title: Ion implantation magnetic bubble element
Inventor: URAI HARUO
IPC: G11C11/14
Filed: 1983-07-07
Abstract: PURPOSE:To sweep out unnecessary magnetic bubble data to each group to the outside of a guard rail by making two bubble generators writing a bubble to two minor groups independent of each other corresponding respectively to the different phase of a rotating magnetic field. CONSTITUTION:In writing a magnetic bubble, bubble generator G1 of an odd number minor loop group 11 is activated at an odd number period m=2n-1 of the rotating magnetic field and bubble generator G2 of an even number minor loop group 12 is activated at an even number period m=2n. Thus, the magnetic bubble data of an odd number only are arranged to the transfer path 41 of the odd number loop group and magnetic bubble data of an even number order only arranged to the transfer path 42 of the even number loop group in the write major transfer path of each loop group. When the magnetic bubble data are arranged in this way and the magnetic bubble is transferred in each minor loop, no unnecessary magnetic bubble remains at all in the write major transfer path. Thus, it is not required to sweep out unnecessary magnetic bubbles to the outside of the memory operation region and then no guard rail is required.

Abstract: PURPOSE:To constitute a simple fast optical switch by driving an optional electro-optic elements among electro-optic elements arranged among plural polarization beam splitters which are arrayed linearly in series and switching splitters where light enters and exits. CONSTITUTION:Optical fibers 1-6 are connectec to the polarization beam splitters 13-17 arrayed linearly in the series through rod lenses 7-12 for convergence.

Patent JP-H02303842-A (JP)
Title: Recorder
Inventor: AICHI TAKAO
IPC: B41J2/01
Filed: 1989-05-19
Abstract: PURPOSE:To remove problems such as stains of a next page or the like by minimizing length of waiting time after discharging paper of a medium to be recorded by a method wherein the case where an area having a recording density exceeding a specific value exists in a recording data, a next record is reverse for the time corresponding to a position at which the high density area exists. CONSTITUTION:When a high density part exists in a recording sheet, time for which execution of a next recording command is reserved after discharging paper is varied according to a position at which it exists. On supposing that, for instance, a Kth part is a last high density part 3, waiting time after discharging paper comes to be calculated by adding one page content recording time X (K-1)/N to minimum fixing time T1. When recording time corresponding to length of discharge opening arrangement is taken as (t), t= one page content recording time/N is obtained. Further, since recording speed is supposed to be constant irrespective of height of recording density in the sheet, time(t) is a value capable of being preliminarily established. Time TK for which execution of a next recording command after discharging paper is reserved when the high density part exists in the sheet can be expressed by the formula TK= T1+(K-1)Xt.
