Abstract: The object of the present invention is to enable to prevent an erroneous erase of a data stored or writing another data on the data as well as to enable to easily switch an erroneous erase prevention switch. A command generator 35, upon reception of a register instruction for checking a state of a memory card 2 received via an S/P & P/S sequencer, sets a state of an erroneous erase prevention switch 23 in a register and transmits this register content via the S/P & P/S sequnecer 31 to a host computer. According to the register content from the memory card, the host computer decides whether a write protect is ON and executes a write inhibit processing when the write protect is ON.

Abstract: A relay driving apparatus has a control circuit, which supplies a first voltage to a relay coil in response to a relay driving signal to turn on a relay contact, and thereafter a second voltage lower than the first voltage to the relay coil to keep an ON state of the relay contact. The apparatus also has a detection circuit, which is connected in a coil current supply path and detects a state change of the relay contact to an OFF state from the ON state based on a current change in the coil current. The control circuit supplies the first voltage again to the relay coil in response to the state change detected by the detection circuit to restore the ON state.

Abstract: The present invention relates to a carrying mechanism usable for successively carrying a plurality of articles to be heated in a heat treating furnace for heat treating the articles. The carrying mechanism of the present invention has wire materials 5 provided to be moved relative to the heat treating furnace and carries the articles 10 by placing the articles 10 on the wire materials 5 and moving the wire materials 5.

Abstract: A memory card is disclosed which has a card body (2) having a concavity (9) formed at the forward end thereof in the inserting direction and in which terminals (5) are disposed and projections (10) are formed between the terminals (5) to prevent the terminals (5) from being touched or accessed from outside. A receptacle for the memory card is also disclosed. The memory card has a simple structure designed to positively protect the terminals and easily let out dust or the like from inside, thereby permitting to assure a positive connection with the receptacle.

Abstract: The continuous heat treatment furnace of the present invention is provided with at least one drying and binder-removing area where drying of the objects to be thermally treated and/or removal of binder are carried out and a firing area where the objects to be thermally treated is fired in succession from inlet side towards outlet side of the furnace, the objects to be thermally treated being subjected to drying and/or removal of binder while being transported through the drying and binder-removing area and thereafter being fired while being transported through the firing area, wherein the heat treatment furnace has at least two transporting mechanisms disposed along the transporting direction of the objects to be thermally treated as transporting mechanisms for transporting the objects to be thermally treated, the objects to be thermally treated are transported by different transporting mechanisms in the drying and binder-removing area and the firing area, respectively, and the transporting speed of each tran

Abstract: A memory card and apparatus used therewith. The memory card comprises a rectangular card body having terminals in the vicinity of one end and a storage device disposed in the card body for storing data. A switch on the card is operable to a state to prevent stored data from being erased; and a status signal representing the state of the switch is supplied to one or more of the terminals. The apparatus with which the card is used has mating terminals to receive the status signal. Depending upon the state of that status signal, the apparatus is selectively inhibited from writing data to the memory card or erasing data stored in the memory card.

Abstract: A memory card is disclosed which has a card body (2) having a concavity (9) formed at the forward end thereof in the inserting direction and in which terminals (5) are disposed and projections (10) are formed between the terminals (5) to prevent the terminals (5) from being touched or accessed from outside. A receptacle for the memory card is also disclosed. The memory card has a simple structure designed to positively protect the terminals and easily let out dust or the like from inside, thereby permitting to assure a positive connection with the receptacle.
