Title: Method for measuring returning torque of throttle lever
Inventor: NISHIYAMA MIKIO
IPC: F02D9/02
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To obtain a method for deciding whether a throttle position sensor is defective or not simultaneously with the measurement of returning torque while lowering the price of a torque measuring unit. SOLUTION: In a throttle body 1 provided with a throttle position sensor 4 having no idle switch, returning torque of a throttle lever 3 is measured. At first, linear output voltage is detected through the throttle position sensor 4 at the full-open position of throttle lever and then a decision is made whether the throttle position sensor 4 is defective or not based on the linear output. The linear output voltage is reset to zero when the throttle position sensor 4 is not defective and the throttle lever 3 is opened by a predetermined angle before being driven to the full-close side. When the linear output voltage reaches a level corresponding to a predetermined angle immediately before the full-close position of throttle lever, driving of the throttle lever 3 is stopped and then the returning torque of throttle lever 3 is measured.

Filed: 1990-10-31
Abstract: PURPOSE:To measure phosphoric acid ions dissolved in water to be inspected accurately by attaching oxidase-pyruvate-fixed film wherein pyruvate oxidase is fixed in a semitransparent-film state. CONSTITUTION:This sensor is constituted of a dissolved oxygen electrode 2 wherein electrolyte X is sealed and a pyruvate-oxidase fixed film (POP-fixed film) 3. The electrode 2 has a container 21. In this container 21, a cathode plate 23 and an anode plate 24 are arranged. A rising part 3b is formed at the periphery of a disk 3a on which the POP is fixed in the fixed film 3. The part 3b is coupled with the lower end of the container 21. Thus, the part is attached to the electrode 2. A detecting part 5 is formed between the fixed film 3 and a gas dialysis film 21. In the detecting part 5, oxygen dissolved in a buffer solution and phosphoric acid in a sample Y to be inspected oxidize pyruvic acid with the POP contained in the fixed film 3 as catalyst and form phosphoric acid. Thus, the oxygen and the phosphoric acid in the sample are consumed. Here, the current across both electrodes 23 and 24 is decreased by the consumption of the oxygen. Since the phosphoric acid and the oxygen are consumed at a constant rate by reaction, the content of the phosphoric acid can be detected when the amount of the current is monitored.
