Title: Roll cross rolling method
Inventor: UEHORI YUUJI
IPC: B21B13/14
Filed: 1982-04-24
Abstract: PURPOSE:To reduce the generation of excessive thrust force and the abrasion of rolls by setting the crossing angle of the shaft of upper and lower paired roll groups beforehand, and correcting the angle of only the shafts of upper and lower work rolls slightly with a change in condition after passing of a plate material. CONSTITUTION:Work roll chocks 1a, 2a can be moved in a rolling direction or be maintained in a prescribed position by the driving mechanism consisting of mechanisms 5a, 5b, 6a, 6b for setting the positions of the work roll chocks provided to backup roll chocks 3a, 4a in order to change the crossing angle of the shaft 4 of upper and lower work rolls 1, 2 with a change in the condition under rolling. The need for any large mechanism for crossing the shafts over the entire part of the paired roll groups during rolling is thus eliminated and the generation of excessive thrust force owing to the crossing of the shaft among the paired roll groups is reduced.

Abstract: PURPOSE: To simplify the structure thereof in order to facilitate the attaching thereof as well as the selection of a type by a method wherein the mirror, independent with respect to the type bar and three surfaces of which are connected, is provided on the type bar.  
     CONSTITUTION: The mirror device M, in which the three surfaces thereof are connected, is provided independently with respect to the type bar 1B and a slant angle adjusting section MA for the mirrors M1, M2, M3 having plane or concave mirror surfaces as well as the securing section MH for the same are equipped at the lower side of the stay MS of a holding body for the device M while a support point MP rotatably securing the mirrors M1, M2, M3 is provided at the lower side of the stay MS. When the type bar 1B is moved longitudinally, transversally and orthogonally on the surface of a type board in order to type a letter under selecting a type, the type bar 1B is moved onto the objective type under reflecting the surface of the type in a searching zone divided into narrower ranges to the mirrors M1, M2, M3 and thus the type is picked up to type the letter. According to this method, the attaching of the mirror is facilitated remarkably while the handling thereof is simplified and the fatigue of eyes may be reduced.

Title: Lead acid battery
Inventor: HOSHIHARA NAOTO
IPC: H01M10/06
Filed: 1980-05-23
Abstract: PURPOSE:To decrease rapid deterioration of the capacity of a battery caused by low- rate discharge, by holding, within a specific range, the concentration of sulfuric acid remaining in the electrolyte at the last stage of the initial low-current discharge. CONSTITUTION:At the last stage of the initial low-current discharge of a lead acid battery where the hour rate of the discharge is below 5 (0.2 C), especially 0.2- 0.05 C, the concentration of sulfuric acid remaining in the electrolyte is suppressed below 20wt%, preferably restricted to 15-5wt%. The simplest method of regulating the sulfuric acid concentration at the last stage of the discharge is, for example,  to carry out discharge in a sufficient acid concentration, before replacing the liquid with sulfuric acid of a given concentration below 20wt%.

Inventor: SATO KOHEI
IPC: B65H75/40
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To lessen external dimension at packaging time by turning a step to both sides of lower parts of a pair of right/left frames for a position in no-use a position in use. SOLUTION: A step 17 capable of turning from a position in no-use to a position in use is provided in a connection pipe 13 connecting right/left frames 4, 5. An engaging protruded part 15 is provided in the right/left frames 4, 5, and an engaged protruded part 20 is provided in the step 17.

Title: Fuel injection valve
Inventor: OGUMA YOSHITOMO
IPC: F02M69/04
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To equalize the injection amount and the spraying shape of fuel to be injected from a nozzle hole to respective directions. SOLUTION: This fuel injection valve has the relationship of 0.1<t/D<0.25 between the distance (t) in the axial direction of a needle valve 25 at the lifting time of the needle valve 25, between the tip surface 25b of the needle valve 25 and a facing surface 32b of a nozzle plate 32 and the pitch diameter D between the nozzle holes 32a, and the relationship of δ/L<=0.2 between the eccentric amount δ from an axis of the needle valve 25 and the lift amount L in lifting of the needle valve 25. Therefore, when a contact part 25a is separated from a valve seat 31a, the flow of fuel to be allowed to flow to the nozzle plate 32 through between the contact part 25a and the valve seat 31a is equalized in the circumferential direction. Moreover, fuels collide with each other without being allowed to directly flow to the nozzle hole 32a, and atomization is promoted.  Therefore, even if the needle valve 2 is made eccentric, the injection amount and the spraying shape of fuel to be injected from the nozzle hole 32a to respective directions can be equalized.
