A method of assembling a butterfly valve that includes a shaft rotatably supported by first and second bearing portions. A first adjusting instrument is used to adjust thrust and radial clearances between the first end of the shaft and the first bearing portion. A second adjusting instrument is used for adjusting thrust and radial clearances between the second end of the shaft and the second bearing portion, and the shaft is arranged at a center of the fluid flow passage.

Disclosed is a digital variable oscillator which has: a cycle change detector for detecting the change of cycle between two input data; a decoder for outputting a predetermined signal in relation to the detection result of the cycle detector; an adder for adding signal output from the decoder a predetermined time; and a frequency adjuster for adjusting the frequency of window signal in relation to the addition result of the adder.

Non-contact type Hall ICs detecting an rotation angle of a throttle valve, a stator core strengthening a magnetic field around the Hall ICs, a lead frame connecting the Hall ICs to an outside ECU are integrated in a sensor cover by resin molding. Thus, the Hall ICs, the stator core, and the lead frame are accurately positioned in the sensor cover. As a result, the Hall ICs are accurately positioned with respect to a permanent magnet disposed in a shaft side of the throttle valve, thereby improving an accuracy of detecting the rotation angle of the throttle valve.

An opening end of a concave portion of a bearing holder is crimped to prevent an outer race of a ball bearing from sliding rearwardly, so that a bearing stop cover in the prior art is not needed to stop the slide-out of the outer race. Thus, the number of parts and assembling procedures for an intake air controller are reduced, thereby reducing the manufacturing const thereof. Further, since the bearing stop cover is not needed, the axial length of the bearing holder of a throttle body is shortened, thereby axially compacting the throttle body.

A hot-wire type flowmeter for measuring a flow rate of a fluid in a passage comprises a pair of support pins extending in parallel with an axis of the passage and an electrical resistor supported between the support pins in the passage. The resistor includes a pipe made of an electrically insulating material, a resistor wire wound on the pipe, and a pair of lead wires. The lead wires are secured to opposite end portions of the pipe and extend in opposite directions and in parallel to each other. The resistor is supported by the support pins through the lead wires.

In one cycle for transferring data, a controller forming a data transfer circuit stores pointer information P_A for periodic transfer and pointer information P_B for non-periodic transfer read from a memory respectively in first and second storage areas. The controller sequentially transfers, to a communication bus, data D_A for periodic transfer and data D_B for non-periodic transfer read from the memory by referring to the P_A and P_B. If transfer by a data length indicated in the P_B has not been completed upon the transfer of the D_B, the controller updates the data length to a data length of the remaining data, and updates an address indicated in the P_B to an address on the memory of the remaining data. In the next cycle for transferring data, the controller reads the remaining data from the memory by referring to the P_B, and transfers the remaining data to the communication bus.

Disclosed is a digital VFO device which comprises a plurality of VFO circuits 12 and 14; synchronous counters 12a and 14a installed in each VFO circuits 12 and 14; and an adjusting circuit 110 selecting one of the VFO circuits 12 and 14 based on signals 113 and 114 representing the peak shift state of an input data 11 output from each VFO circuits. Correcting instruction signals 16 and 17 are generated to correct the synchronous counter of the other VFO circuits by substituting the counter value of the synchronous counter of the VFO circuit selected by the adjusting circuit 110 for the synchronous counter of the other VFO circuits.
