Abstract: PURPOSE:To reduce the cost of subscriber's lines in an exchange. CONSTITUTION:In the case of receiving a dial pulse from a terminal 300 and sending a pushbutton(PB) signal to a transmission time division multiplex bus 201, a timing generator 30 switches a call/PB signal switching part 10 based upon loop information detected by a terminal interface part 50 and the switching part 10 extracts dial pulse data and sends the extracted data to a PB signal selecting part 20. The selecting part 20 judges a corresponding PB signal, a PB signal receiving part 21 collates a time slot to which the PB signal concerned is supplied and fetches the PB signal from a reception time division multiplex bus 202 and the switching part 10 transmits the PB signal to a prescribed receiving terminal. A time slot table has been previously registered in the receiving part 21 by a CPU 40.

Title: Overcurrent tripping device
Inventor: OISHI HIROTOSHI
IPC: H01H61/02
Filed: 1989-10-13
Abstract: PURPOSE:To quickly actuate a tripping mechanism and also reduce a variation of radiation heat impinging on a bimetal by fixedly attaching the bimetal so that the plane of a heater and that of the bimetal are approximately perpendicular to each other and the bimetal is fixed to the middle portion of the heater. CONSTITUTION:When a current flows between a terminal B and a lead wire 5, a heater 9 produces heat, by which a bimetal 10 bends in the direction of A. When the current flowing in the heater 9 becomes an overcurrent, the bimetal 10 is more bent to actuate the tripping mechanism of a relay and cut off the current. As the bimetal 10 is fixedly attached to the middle of the heater 9 whose temperature is high, heat is so quickly conducted that the current can be cut off without delay. Moreover, the planes of the heater 9 and the bimetal 10 are perpendicular to each other so that the radiation heat, from the heater 9, impinging on the bimetal 10 is small and a variation of this radiation heat due to the bent of the bimetal 10 is also small and resultantly, the operation is stabilized.

Title: Control method of actual temperature of intermittently operated heating means
Inventor: HAINRITSUHI SHIYUUKU
IPC: G05D23/20
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To control actual temperature of an intermittently operated heating means. SOLUTION: At least a single operation parameter is measured for a prescribed measuring period T in a switch-on period 86 of a heating means. An actual temperature of the heating means is detected on the basis of a measured value of at least this single operation parameter. A length of the switch-on period 86 at that time is changed on the basis of a compared result of the actual temperature and a prescribed target temperature. The shortest length of respective switch-on periods 86 is equal to the measuring period T. The measuring time T is selected on condition that heat energy supplied to the heating means in a length of the measuring time is successively smaller than heat energy generated in a switch-off period 88 extending up to the next switch-on period.

Title: Electronic metronome
Inventor: KANEKO MASAO
IPC: G04F5/02
Filed: 1984-12-18
Abstract: PURPOSE:To decrease noise and to extend a battery life by driving back and forth a tact bar by an electromagnetic conversion part. CONSTITUTION:A permanent magnet 14 continues to oscillate back and forth by a series of attraction and repulsion effects when coil bodies 15, 16 are ener gized. The tact bar 4 supported pivotally to a tact fulcrum 13 can be oscillated back and forth as well. The tempo of such forward and backward oscillation can be selected as desired by changing the electric signal to be fed to the bodies 15, 16 and the same oscillation amplitude can be assured at any tempo by adjusting the intensity of the electric signal. The tact bar 4 is directly driven by the electromagnetic conversion part in the above-mentioned manner and therefore the rotation transmission parts are decreased, by which the noise is decreased and the less driving torque is required. The extension of the battery life is thus made possible.
