Abstract: A machine tool having a transparent observation window on a front surface of a cover that encloses a machining area space, and a display device provided in the observation window that becomes transparent or semi-transparent when a displayed image disappears. A control panel may be arranged below the observation window.

Abstract: A device asserts a first wired OR signal line to a low level. This asserted state is transferred to a second system via a first mask mechanism. The second assert mechanism asserts a second wired OR signal line. This asserted state is similarly communicated to a first assert mechanism to maintain the signal line in an asserted state. The device that has made the assertion is processed. Then, values in a first and second registers are changed to negate outputs from the first and a second mask mechanisms. It is verified that the first and second wired OR signal lines have been brought into a negate state. The values in the first and second registers are returned to the initial ones. A switching operation is performed so that each of the first and second mask mechanisms output the state of the wired OR signal line, to return to the initial state.

Abstract: A pulse transfer system is provided by which a pulse signal output from a manual pulse generator unit is transferred to a numerical control apparatus through a wireless channel. Pulses are generated in accordance with the rotation of a knob of the manual pulse generator and are counted from a reference time by a counter. A numerical value of the counter is modulated by a modulation circuit, amplified by a power amplifier circuit, and transferred as a coded signal from an antenna to a numerical control apparatus at each predetermined time. The numerical control apparatus receives the coded signal through the wireless channel and recognizes the pulses from the manual pulse generator. The coded signal transferred from the manual pulse generator unit through the wireless channel is a signal as an absolute position using time as a reference, and thus even if an error occurs during the transfer, the correct number of pulses can be recognized.

Abstract: A floppy disk drive apparatus in which, when a floppy disk is used as the memory medium for numerical control data, control is performed in such a manner that data to be transferred via an interface (4) is read out whenever there is a data transfer request from a numerical control unit (8). In particular, to an arrangement where a data read head is constantly in contact with the floppy disk, disk wear is made as small as possible by stopping the drive motor as the occasion may demand, and it is necessary that data be transferred to the numerical control unit without interruption. The drive apparatus of the invention performs optimum drive control in terms of prolonging the service life of the disk.

Abstract: An improved splicer for editing a recording tape having a pair of rows of equally spaced apart sprocket holes along both sides thereof is disclosed which includes a base having a groove adapted to receive the recording tape, a plurality of pins planted on the groove and engageable with the sprocket holes to position the recording tape in the groove in a predetermined location relative to the sprocket holes, a cutter secured to the base for cutting the recording tape placed in the groove, and a splicing member for joining two abutting tapes placed in the groove. The improved cutter which includes a stationary blade fixedly secured to the base; an inner, movable blade pivotally supported by the stationary blade and cooperable therewith to cut the recording tape placed in the groove; and an outer, movable blade pivotally connected to the inner blade and cooperable therewith to cut the recording tape placed in the groove.

Abstract: An apparatus for preparing data for controlling the sequence of broadcasting, which apparatus comprises: a broadcasting material editing unit that edits a broadcasting material such as a broadcasting telecine film or broadcasting video tape, an adaptor with which the broadcasting material related information from the broadcasting material editing unit is converted to time-related data; a command only keyboard for preparing broadcast sequence control data; and an I/O device that feeds a broadcast sequence control unit with an output signal from the command only keyboard and an output signal from the adapter. The broadcast sequence control unit performs the necessary operations for preparing broadcast sequence control data. An output device stores or records the broadcast sequence control data which has been processed with the broadcast sequence control unit.

Abstract: In providing overlapped displays of characters and graphics on a display unit, character data are arranged in the order of rows, while graphic data are divided into blocks corresponding to the rows of the character data and the data, which are extracted from the respective blocks in the order of lines, are arranged for each line in the order of the blocks. This eliminates the necessity of providing a remainder of address for each row which is instead provided at the end of each line of the graphic data so as to permit the transition to the next line by shifting the high-order digit of the address, and accordingly the utilization efficiency of a RAM is increased.

Abstract: A low power consumption type tape reader permits miniaturization of reel motors and ensures stopping a tape (3) at a first rewind stop code, even if the response of a brake magnet (11) is somewhat poor. When a rewind command is received, the rotational speed of a capstan motor (12) is switched from a forward low speed to a reverse low speed, and then a feed magnet (14) is actuated to rewind the tape (3). The rotational speed of the capstan motor (12) is gradually increased to a reverse high speed. When a rewind stop code is detected, the speed of the capstan motor (12) is gradually decreased to the reverse low speed, and then the brake magnet (11) is actuated to stop the feed of the tape (3) temporarily. A reversible counter (40) stores the number of rewind stop codes detected during the time interval between the detection of the first rewind stop code and the temporary stopping of the feed of the tape (3).

Abstract: A system for exchanging data between a microprocessor (1) and an auxiliary memory device (10) connected to the microprocessor (1). A plurality of data exchange common RAMs (24, 25) are arranged in the auxiliary memory device (10), and the operating states of the common RAMs (24, 25) are stored in memory means (26, 27), respectively. Data exchange is performed through a common RAM (24, 25) which is not being used in accordance with the storage content of said memory means (26, 27), thereby decreasing the waiting time for data transmission/reception.

Abstract: An apparatus for controlling the writing of data from a processor into a memory having different read and write times, wherein the memory is connected directly to the processor through address and data buses without the use of an input/output port. A timer circuit is connected to the buses and memory and is controlled by the processor to produce a write timing signal which controls the writing of data into the memory. The processor is placed in a holding state, based on the write timing signal, for a period long enough to assure that the data will be written into the memory in its entirety.
