PURPOSE:To prevent early capacity drop in deep charge-discharge cycles by adding a potassium salt of ethylenediaminetetraacetic acid to an electrolyte. CONSTITUTION:In a paste type lead-acid battery using a lead-calcium group alloy grid, a potassium salt of ethylenediaminetetraacetic acid is added to an electrolyte. By adding this salt to the electrolyte, early capacity drop in deep charge-dischar...

PURPOSE:To prevent early capacity drop in deep charge-discharge cycles by adding a potassium salt of higher fatty acid to an electrolyte. CONSTITUTION:In a paste type lead-acid battery using a lead-calcium group alloy grid, a potassium salt of higher fatty acid is added to an electrolyte. By adding this salt to the electrolyte, early capacity drop in deep charge- discharge cycles which is a proble...

A surgical instrument for uterocervical conisation. It includes a holder member (1) for diathermic wire (6), this member being intended for mounting in a pistol grip. The wire (6) is tensioned by the holder member such that the wire forms an angle alpha to the longitudinal axis of the holder member, the wire cutting out a cone when the member is turned through a complete revolution. The angle al...

PURPOSE:To prevent a processing from being interrupted by switching the kind of operation and an increment value in one operation based on the specification of a parameter indicating an operation switching period and a parameter indicating an increment value switching period. CONSTITUTION:When a vector 27 exists in a main storage 6, the elements 6, 2 of the vector 27 are compared by a minimum/maxi...

Processing arrangement for enhancing signal contours of a signal, having a transition zone between low-amplitude and high-amplitude areas, including a device for multiplexing the samples of the input signal processed during the duration of the transition zone and non-processed samples located outside said zone. This multiplexing device is preceded by a first non-processed input sample transfer pat...

PURPOSE:To use a display part also as an operation switch group in common by selectively detecting the light of a weak lighting LED on a matrix array by a photosensitive pen and converting the light into address information to control the display lighting of the LED. CONSTITUTION:The LEDs on the matrix array are weakely lighted by column selecting pulses to be successively repeated, row selecting ...

The invention relates to a sheet moulding compound (SMC) comprising a basic layer (3) consisting of thermosetting material, fillers, fibres and customary additves, one side of which is provided with two layers, an intermediate layer (2) and a top layer (1), the intermediate layer of which lies against the basic layer, the intermediate layer comprising at least fibre reinforcement and thermosetting...

PURPOSE:To facilitate an easy process for the defective mask of a data storage unit, by installing a storage unit of major-minor structure containing a minor loop of 1-bit length in addition to a storage unit of major-minor structure for data. CONSTITUTION:The 2nd storage unit for data consisting of a minor loop 202, major lines 203 and 206, a detector 204 and others plus the 1st storage unit for ...

PURPOSE:To produce a novel compound containing hypoxanthine base by treating an adenine base-containing compound with adenosine deaminase, etc., and to use the compound as an antiviral agent. CONSTITUTION:Adenine base-containing compound shown by formula II is reacted with adenosine deaminase in 1/10 M phosphoric acid buffer solution (pH 7) at 25 deg.C for several hours to forma novel hypoxanthine...
