摘要： Two A.C. output signals amplitude-modulated in accordance with two function values (sine and cosine) differing from each other in correspondence to a position-to-be-detected are received from a position sensor such as a resolver. By performing an addition or subtraction between a signal derived by shifting the electric phase of one of the received A.C. output signals by a predetermined angle, and the other received signal, two electric A.C. signals (sin(&ohgr;t±d+&thgr;), sin(&ohgr;t±d−&thgr;)) are electrically synthesized which have electric phase angles (&thgr;) corresponding to the position-to-be-detected and are phase-shifted in opposite directions. “±d” here represents phase variation error caused by factors, other than the position-to-be-detected, such as temperature change. In the synthesized two signals, the phase variation errors (±d) appear in the same direction, while the phase differences (&thgr;) corresponding to the position are shifted in opposite, positive and negative, directions. Thus, by measuring the respective phase shift amounts (±d+&thgr;, ±d−&thgr;) and performing appropriate operation, it is allowed to cancel out or extract the error (±d) so that an accurate phase difference (&thgr;) can be detected. Position detection data indicative of the detected phase difference (&thgr;) is converted into a pulse-width-modulated signal and transmitted in the pulse-width-modulated form.

摘要： There is disclosed a sample sucking pipe the manufacture of which is easy and which is also advantageous costwise, whose strength is relatively great and whose usage life is long and with which it is possible to prevent the occurrence of trouble such as dust clogging and sample leakage. There is also disclosed a method for manufacturing the same. A sample sucking pipe P is for sucking samples of blood contained in a sample vessel T through a rubber cap C, and is made up of a sucking pipe 10, a venting pipe 20 and a holding piece 30. The pipes 10, 20 are made of the same stainless steel. The holding piece 30 is made of polyacetal resin. The pipes 10, 20 are disposed parallel with each other with their tip ends aligned and then integrated by welding carried out along the tip end portion of the contacting part of their walls. A sucking opening 13 and a venting opening 23 are provided in the walls of the pipes 10, 20 respectively and, on the tip end side of these openings, the pipe passageways of the pipes 10, 20 are closed with rod-like members made of the same material as the pipes.
