摘要:
An automatic wire extension method capable of effecting reliable and smooth wire extension regardless of the size of the diameter of an initial hole and even with use of an inexpensive apparatus, such that during the wire extension through an initial hole having a normal diameter, when a wire electrode is fed while a machining fluid is injected toward a workpiece (50) from a wire extension nozzle (120) attached to an upper wire guide (30) and set apart from the workpiece, the wire electrode is reliably threaded into the initial hole (51) and a wire passage of a three-point support guide (72) accommodated in a lower wire guide, due to a wire guiding function provided by the machining fluid jet. A wire extension through a small-diameter initial hole, when a wire extension nozzle (120) having a nozzle hole (125) with a diameter smaller than that of the initial hole (51) is attached to the upper wire guide, and the wire electrode is fed through the nozzle with the nozzle positioned close to the workpiece and with the supply of the machining fluid interrupted, the wire electrode is threaded into the small-diameter machining hole close to the nozzle, and then into the wire passage of the lower wire guide due to a wire guiding function provided by the initial hole.

A drive system for a thin-film EL matrix display panel includes first and second voltage doubler circuits and a DC booster circuit. A 1/4V.sub.M voltage, which has the 1/4 voltage level of the modulation voltage, is applied to the first voltage doubler circuit of which an output voltage is applied to a modulation voltage applying circuit. The 1/4V.sub.M voltage is further applied to the DC booster circuit which develops an output voltage having a voltage level of 1/2V.sub.W. The thus obtained 1/2V.sub.W voltage is applied to the second voltage doubler circuit of which an output voltage is applied to a write voltage applying circuit.

A method for driving a thin-film electroluminescent (EL) display panel comprises the steps of charging the EL display panel by applying to the EL display panel a voltage of KV.sub.0 where V.sub.0 is a voltage for emitting electroluminescence from the EL display panel and K is more than zero and less than 1, and applying the voltage of V.sub.0 to the EL display panel, whereby the EL display panel is driven with a stepwise driving pulse due to the capacitance feature of the EL display panel. A circuit for enabling the method is also provided.

An elevator control system for controlling a plurality of elevator cars arranged for parallel operation for servicing a plurality of service floor landings of a building, in which means are provided so that, in response to origination of a new hall call in addition to hall calls originated and allotted already, a suitable car for servicing this new hall call can be selected and the new hall call can be allotted to the selected car to be serviced by the selected car. In the system, the change in the service condition of all the cars for the already allotted hall calls due to allotment of this new hall call thereto is taken into account in selecting the suitable car. For example, means are provided for computing for each car the forecast waiting time at each of the already allotted floors to be serviced thereby to detect the change in the forecast waiting time when this new hall call originating floor is serviced. The new hall call is allotted to the car which provides a forecast waiting time less than a predetermined limit, and this car services this specific floor.
摘要:
Apparatus for detecting the number of objects such as the number of persons located within a predetermined area. Ultrasonic wave is emitted toward the objects, the number of which is to be determined, and the reflected waves from the objects are received by a receiver. Among the received reflection waves, the waves having an amplitude greater than a predetermined peak value are derived as the useful reflection wave signal having a constant peak value. The number of the objects is determined based on the quantity of the derived reflection wave signals having the constant peak value. By emitting the ultrasonic wave for every unit time, the derived reflection wave signals having the constant peak value may be averaged by means of a smoothing circuit.

A press machine includes a controller including a top-dead-center detector adapted to: rotate a main shaft in a predetermined direction selected from a normal rotation direction and a reverse rotation direction to place a slide at a first position displaced relative to a top dead center of the slide by a predetermined height; while outputting and counting pulses from an angle detector, rotate the main shaft in a direction opposite to the predetermined direction to move the slide to a second position located at the same height as the first position beyond the top dead center; and rotate the main shaft from the second position in the predetermined direction by an amount corresponding to a half of the counted pulses to detect the top dead center.
