IPC: B66C23/90
Filed: 1993-12-27
Abstract: PURPOSE:To accomplish a load hoisting work even if a gantry for supporting tension applied to a support rope is put in the low gantry state. CONSTITUTION:An overload preventing device of a crane is provided with a gantry height detecting device 14 comprising a limit switch 8 for detecting the angle of inclination of a compression member 7a for forming a gantry 7 and a contact member 9, and according to an electric signal from the detecting device, it is determined whether the gantry 7 is in the high gantry state or in the low gantry state. If the limit load according to the height of the gantry 7 and the boom hoisting angle of the boom 3 is stored in a control part of the overload preventing device, the limit load in the low gantry state is calculated, and even if the gantry 7 is in the low gantry state, there is no possibility that a crane 1 is broken and a support rope 4 is broken.

Title: Battery having metal hydride electrode
Inventor: EBATO NOBORU
IPC: H01M4/62
Filed: 1990-11-30
Abstract: PURPOSE:To suppress the deterioration of electrode performance by connecting mutual hydrogen storage alloy particles of the negative electrode main component of an electrode containing a hydrogen storage alloy as a main component, or the hydrogen storage alloy with an electrode base body by an uniform mixture of a conductive agent and a rubber binder. CONSTITUTION:In a metal hydride electrode, for example, powder of LaNi4.7 Al0.3 is used as a hydrogen storage alloy. An uniform mixture of nickel powder and EPDM rubber is sufficiently mixed with this powder together with a small amount of xylene to form a paste, which is then applied to a nickel mesh and dried followed by press, and a collector terminal is welded thereto. The resulting electrode is opposed to a nickel electrode to form an open type cell. Thus, even if the hydrogen storage alloy powder is refined by a volume change accompanied by the charge and discharge of the hydrogen storage alloy, the breakage and powdering of the electrode can be avoided by the rubber elasticity of the binder to keep the form, the electric connection with the electrode base body can be held, and the deterioration of the electrode can be suppressed.

Title: Wiper
Inventor: KAWASE SHIGERU
IPC: A47L13/16
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To improve cleaning workability by a method wherein dishcloths are at least doubled and closed with a string to form at least four surfaces as wiping surfaces and when the surfaces are fouled, the dishcloths are properly folded or turned inside out on use to allow application with a reduced frequency of troublesome washing. SOLUTION: Dishcloth is doubled and closed, for example, by a string 2 or the like to be formed into a cylinder as wiping device. In application, the wiping device is folded in two to fit one side thereof into the other side so that the wiping surfaces 1, two surfaces, are made to be used. When the surfaces are fouled during the application, the wiping device is turned inside out to draw new wiping surfaces 1 to the face. By repeating the inversion and folding, cleaning is accomplished using eight surfaces in total without washing by water in the course of the cleaning work. This enables reduction in the frequency of troublesome cleaning while preventing recontamination as caused by fouled surfaces effectively using the total available area of the wiping device.  Thus, re-using is possible simply by one washing by water required after the using of the eight available surfaces thereby yielding an effect of a multiplied use in one sheet of the wiper.
