Filed: 1987-02-04
Abstract: PURPOSE:To reduce the direct manufacture cost of a rotator by assigning a tooth form on the pitch curve of two elliptic gears whose pitch curves are expressed by a specific polar equation, and approximating the tooth surface by an arc close to an involute curve. CONSTITUTION:The tooth form is assigned on the pitch curve of the two elliptic gears whose pitch curves are expressed by the polar equation I. Then the tooth form is formed by wire-cutting discharge machining while a tooth form assigned to a point Ak is used as one tooth of a spur gear having a pitch circle Ch which has its center at Ok and a radius rhok. The tooth surface is determined by approximating the involute curve constituting it by >=1 arc and using the center coordinates and radii of the arcs and the intersections of the arcs and addendum circles and the arcs and dedendum circles. Consequently, the shape of the rotator for the flowmeter is determined in a short time to manufacture the rotator, and the direct manufacture cost is reducible.

Abstract: PURPOSE:To reduce the size and weight of the titled device and enhance the reliability of the device, by discriminating whether an operation of a plurality of independent movable mechanisms of a motive power transmitting mechanism is correct, based on a detection signal from an operating position detector. CONSTITUTION:With a clutch solenoid 21 turned ON, a platen 1 is rotated to feed a paper. With the solenoid 21 turned OFF, an ink ribbon system is controlled, and a ribbon down state sensor is turned ON. For example, a driving circuit for the solenoid 21 is broken, the platen 1 is not rotated even when the solenoid 21 is turned ON and a feeding motor 18 is rotated in order to rotate the platen 1, and the ribbon down state sensor is switched from an ON state to an OFF state. Since it is naturally necessary that the platen 1 be rotated and the ribbon down state sensor be maintained in the ON state, the condition is discriminated to be abnormal. Accordingly, whether the operation of a movable mechanism is correct can be detected based on a signal from an operating position detector.

Abstract: PURPOSE:To make a microcomputer sufficiently execute other work even when transmission speed is fast while reducing the load of the microcomputer by providing a pulse width transform circuit, two-phase clock generating circuit and AMI (Alternate Mark Inversion) waveform output circuit. CONSTITUTION:At an AMI driver 2, when the bit data of the transmitting data is '0', a pulse width transform circuit 4 transforms the pulse width to 1/2 H level pulse width. A two-phase clock generating circuit 5 divides the transformed pulse to the (+) side and (-) side data of an AMI waveform and an AMI waveform output circuit 6 outputs the AMI waveform to a bus cable 3. Thus, at a microcomputer 1, timer interruption is loaded at the speed as the data transmission speed and since the transmitting data in a memory is outputted from a port while being shifted for one bit each time, the work amount of the microcomputer can be reduced.
