Abstract: To heat an object locally by automatically recognizing a shape of the object and emitting an electromagnetic wave based on the shape without enlarging a device size. An electromagnetic wave heating system comprises a heat chamber having a wall surface, in which an object is placed to be heated, a flat antenna arranged on the wall surface of the heat chamber and configured to emit the electromagnetic wave so as to heat the object inside the heat chamber, and a controller configured to control a movement of the flat antenna. The flat antenna comprises a plurality of antennas arranged in an array manner, and the controller detects a shape or a temperature distribution of the object based on a reflected power that is generated when the electromagnetic wave is emitted from the plurality of antennas, and determines a size of microwave supplied into each of the plurality of antennas based on a detection result thereof.

Abstract: To realize a reduction in size of an electromagnetic wave heating system that utilizes water vapor. The electromagnetic wave heating system comprises a heat chamber having a first wall surface and a second wall surface different from the first wall surface, in which an object is placed to be heated, a flat antenna arranged on the first wall surface of the heat chamber and configured to emit an electromagnetic wave so as to heat an object inside the heating chamber, a discharger arranged on the second wall surface and configured to generate a discharge plasma by occurring a high voltage through a resonation structure of the electromagnetic wave, and an oscillator formed by a semiconductor element and configured to output the electromagnetic wave, and it is configured that the electromagnetic wave outputted from the oscillator is supplied into the flat antenna and the discharger.

Abstract: A spindle phase indexing device for a machine tool is equipped with a guide rail detachably or fixedly attached to a table, a phase indexing jig configured to travel on the guide rail and which includes a first fitting part, a cutting tool including a second fitting part configured to be fitted with the first fitting part, and a controller configured to store therein a phase of a spindle at a point in time when the first fitting part and the second fitting part are fitted together. The first fitting part and the second fitting part are formed such that rotation of the cutting tool is constrained when the first fitting part and the second fitting part are fitted together.

Abstract: A tool holder on which a nonrotational tool is mounted is mounted on a spindle of a machining center. A tool holder body of the tool holder includes a positioning pin that is inserted into the machining center and a locking mechanism. When the positioning pin is not inserted into the machining center, the locking mechanism locks the rotation of the tool holder body relative to a drive shaft. When the positioning pin is inserted into the machining center, the locking mechanism allows the rotation of the tool holder body relative to the drive shaft.

Abstract: A primary object is to provide a communication apparatus, in particular, its buffer memory which conforms mainly to specifications of SAE-J1850 or ISO-9141.

Abstract: A microcomputer which is desired to be small and lightweight comprises an EPROM for storing an operation program for the microcomputer, a selection circuit which opens a gate connected to the ERPOM through the input of an address allocated to the EPROM, and another selection circuit which opens a gate connected to a circuit for storing a fixed value through the input of another address, thus eliminating a verification error which often occurs at the time of writing a program into the EPROM.
