Title: Position detecting device
Inventor: HAKATA YOSHITAMI
IPC: G01B21/00
Filed: 1983-03-24
Abstract: PURPOSE:To prevent a step-out phenomenon and to reduce errors at the time of sampling, in a position detecting device using a resolver, by controlling the degree of following of the second signal with respect to the first signal, which is phase-modulated in response to mechanical-or electric-quantity change basd on the third signal corresponding to the time interval, wherein the phase difference between the first and second signal is present. CONSTITUTION:A signal (b) is the output of the final stage of a follow-up counter 115. When there is any phase difference between the signal (b) and a signal (a), a signal +1 or -1 is given, follow-up correcting circuits 113 and 114 are actuated, and the counting state of the follow-up counter 115 is corrected so that its output (b) is made to agree with the signal (a). The degree of occurrence of the signal +1 or -1 can be controlled on both rising and falling sides of the signal (a), and the phase difference between the signals (a) and (b) is quickly overcome. Namely, the phase of the signal (b) of the output of the signal state of the follow-up counter 115 is controlled so that the signal (b) follows the phase of the signal (a). Therefore, even though the rotary speed of the rotor of a resolver is increased, troubles such as step-out phenomenon do not occur, and a position counter 118 counts a clock signal phi3.

Title: Method for monitoring oil leakage
Inventor: OCHIAI TAKASHI
IPC: G01M3/20
Filed: 1982-03-26
Abstract: PURPOSE:To detect oil leakage with high sensitivity, by adding rhodamine B beforehand in a water-soluble working fluid, irradiating excitation light to the liquid to be monitored such as waste water contg. the oil leaking from a hydraulic cylinder and measuring the intensity of fluorescence by the rhodamine B. CONSTITUTION:Rhodamine B is added up to about 1,000ppm to a water-soluble working fluid (consisting essentially of glycolic compds.) to be used for hydraulic cylinders of hot rolling mills, etc. For example, when the working fluid leaks and is mixed together with the cooling water for rolling rolls into a waste water system, the sample water which is passed through a filter 12 and is thus removed of foreign matter is flowed through a fluorescence measuring cell 13. The light of an Xe lamp 14 is divided to excitation light of 500-550nm by a spectroscope 15 for excitation and is then irradiated to the cell 13. Only the light of 550-600nm is removed with a spectroscope 16 for emission of light, and the intensity of fluorescence is measured with a detector 17. The electric signal thereof is converted to a concn. with a data processing device 18, and the concn. of the rhodamine is displayed on a display 19. The oil leakage is thus detected quickly and continuously.

Title: Ignition circuit of internal combustion engine
Inventor: MIURA SHIYUNJI
IPC: F02P3/055
Filed: 1980-04-15
Abstract: PURPOSE:To obtain a sufficiently large igniting energy by flowing a large current required for the main transistor constantly irrespective of the volume or waveform of the induction voltage of an ignition coil. CONSTITUTION:When a voltage which is positive on the side of a terminal A is induced at the primary winding 31 of the ignition coil 3, a current flows to the base of the main transistor 1 through between the terminals S and D of FET5, whereby the main transistor 1 is made conductive. Since the current flowing through FET5 is constant even when the voltage between A and C rises, the short-circuit current flowing to the main transistor 1 is kept fixed. When the voltage rises furthermore, a subtransistor 2 is made conductive. Thereby the main transistor 1 is interrupted and a large output voltage is generated at the secondary-side winding 32 of the ignition coil 3, whereby an ignition plug 4 is made to spark.

Abstract: PROBLEM TO BE SOLVED: To suppress a faint vibration in a yoke itself, and prevent the yoke from resonating for prevention of unpleasant noise by mounting a vibration-proof material formed out of roughly circumferential-shaped elastic resin or rubber which is brought into close contact with the opening-side peripheral surface in a yoke side surface, and a metallic C ring pressing the vibration-proof material against the yoke on the inner peripheral surface of the vibration-proof material. SOLUTION: A yoke housing 4 has an opening in one end, and a cylindrical from having a bottom on the other end. A strip rubber sheet 8 is fixed as a vibration-proof material on the inner wall opening end side of the yoke 4, and a metallic C ring 9 is compressed and mounted therein. The instantaneous faint vibration of the vibration of the yoke 4 is absorbed by the cushion action of a vibration-proof material 8. The metallic C ring 9 mounted on the inner peripheral surface of the vibration-proof material 8 presses the vibration-proof material 8 against the yoke 4, the adhesion of the yoke 4 and the vibration-proof material 8 increases for improvement to vibration isolating effect. The metallic C ring 9 itself prevents such deformation that the opening side of the yoke 4 is narrowed, so that periodic large vibration is absorbed.
