    摘要: An I/O unit has a fixed unit such as a housing provided with a multiplicity of connection terminals and an LED display module unit. A mounting/dismounting unit is provided with a terminal block including connection terminals to be coupled with the connection terminals of the fixed unit. The mounting/dismounting unit has a hinge disposed at an end thereof and the fixed unit has a pin and a grip capable of being engaged with the hinge. The grip is pulled out to a position to be used and then further pulled out, whereby the mounting/dismounting unit is forced out, drawing an arc about the pin and separated from the fixed unit. With this arrangement, an I/O module with a mounting/dismounting unit capable of being easily removed is provided.

    摘要: A programmable logic control (PLC) device for executing a logical operation process of a sequence for program. The PLC device includes a PLC control unit (10) and a high speed input/output module (20) capable of executing a logical operation at a high speed in response to an external input signal and externally outputting a result of the logical operation, whereby an external signal to be processed at high speed can be processed without using a special processing unit.

    摘要: A method of preparing para-chlorotoluene by the electrolytic chlorination of toluene in an aqueous solution of hydrogen chloride or a metal halide as an electrolyte by passing an electric current from a cathode to an anode, both of which are immersed in the electrolyte, in order to form an active chlorine species which then reacts with toluene to produce the desired para-toluene. The anode is made of a carbonaceous material having cyclodextrin or a derivative thereof bonded onto its surface. The toluene that is introduced into the aqueous solution of electrolyte is included as a clathrate compound within the cyclodextrin.
