  • Patent number: 11569774
    Abstract: An actuator control device supplies electrical power to a plurality of actuators via a plurality of controller units consecutively disposed and connected in one direction. A power supply unit or an input/output and power supply unit is interposed between each arbitrary number of controller units from within the plurality of controller units. In a case that the power supply unit is interposed, the power supply unit supplies electrical power to the block connected on a downstream side in a connecting direction. In a case that the input/output and power supply unit is interposed, the input/output and power supply unit performs input and output of signals to and from an exterior and the block that is connected on the downstream side in the connecting direction, while also supplying electrical power to the block.

  • Patent number: 10063004
    Abstract: A controller assembly includes a plurality of controller units, and a heat dissipating unit interposed between the controller units. Male and female connectors are disposed in the controller units, and the connectors thereof are fitted to female and male connectors of the heat dissipating unit to thereby establish electrical contact therebetween. Upon driving electric actuators, heat generated in circuit boards of the controller units is dissipated to the exterior through a plurality of heat dissipating protrusions provided on the heat dissipating unit, so that heat generating sources of the circuit boards are cooled.

  • Patent number: 4650667
    Abstract: Gas-emitting bath additive compositions are stably preserved over a long term. They comprise a carbonate, an organic acid, and a stabilizer which is selected from magnesium oxide, sodium aluminate and a mixture thereof. Magnesium oxide and sodium aluminate are effective to improve the preservation stability of bath additives when used in an amount of 0.1 to 1.5 wt % of the total composition.
