Filed: 1984-02-03
Abstract: PURPOSE:To reduce the decrease in the amount of electrolyte so as to improve the life of a sealed lead storage battery used either in a trickle charging state or in a floating charge state by coating the surface of the battery jar with metallic foil having a very small steam permeability. CONSTITUTION:When constituting a sealed lead storage battery which is used in a trickle charging or floating charge state and in which oxygen gas produced during charging is absorbed by the negative plate, a member formed by affixing films 1 made of a polyester resin or similar material to the surfaces of metallic foil 2 with a thickness of 10-200mum made of aluminum or similar material is stuck to the surface of the battery jar by means of an adhesive 3. Therefore, due to the very small steam permeability of the metallic foil 2, the decrease in electrolyte can be suppressed even when charging is performed under a condition of high ambient temperature. As a result, the increase in the internal resistance and the deterioration of the capacity of the battery are alleviated, thereby improving its life.

Title: Microprogram controller
Inventor: OWADA TATSUO
IPC: G06F9/26
Filed: 1987-01-30
Abstract: PURPOSE:To shorten the processing time of a microprogram controller by storing a flag showing the state of the value stored in a register into a flag memory circuit in response to the register when the value is stored in the register. CONSTITUTION:A register circuit 1 selects the value instructed by a microinstruction and stores it in a register. A flag generating circuit 17 checks the received value to be stored in the circuit 1 and produces a flag showing the state of said value. A flag memory circuit 2 reads out the flag produced by the circuit 17 and stores the flag which is decided by the microinstruction and read out in response to the register to output the flag in response to an instruction. Thus it is not required to carry out the microinstruction to produce a flag via an arithmetic circuit in order to check the value stored in the register. As a result, the microprogram processing speed is increased and the processing time can be shortened with a microprogram controller.
