Title: Method and equipment for recognition of leakage
Inventor: BUCK RAINER
IPC: F02D41/22
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To enable recognition of even a small leakage, by detecting at least two pressure values at different time points, and setting up fuel amount balance, on the basis of the pressure values. SOLUTION: A specified control signal is applied to a pressure control valve 40. A first pressure value is detected with a pressure sensor 50. Spouting fuel mass MF is read from a characteristic map. Jet fuel mass ME is calculated depending on the number of revolution N and a desired running mode FP. Return fuel mass MR is read from a storage device. At a time point t2 , a second pressure value P2 is detected with the pressure sensor 50. Leakage fuel mass ML is calculated by using a specified formula. Whether the leakage fuel mass ML is larger than a threshold value SW is inspected. When the mass ML is larger than the threshold value SW, leakage generation is recognized, and a suitable treatment is executed. In the other case, airtightness of system is recognized.  Thereby the monitoring of airtightness of the whole high pressure fuel supply system is enabled, and the leakage to the outside can be also recognized.

Title: Torque detector
Inventor: HORIKOSHI SHIGERU
IPC: G01L3/10
Filed: 1984-02-10
Abstract: PURPOSE:To reduce the dependence in temperature with a small size by provide a circumferential groove at the opposed part between a rotating shaft and an excitation core to create a thrust gap. CONSTITUTION:As an alternating current flows through excitation coils 4 and 5, a magnetic flux flows as shown by the broken line passing through an excitation core 7 and a rotating shaft 1. Since the magnetic flux flows through thrust gaps 1 and 2 and radial gaps 9 and 9', the magnetic resistance at the gap part lowers to increase the magnetic flux. As for a signal processing means, when a torque is applied to the rotating shaft, the magnetic resistance of the shaft changes due to a reverse effect of magnetic distortion and causes an imbalance in the induced voltage of a secondary coil to generate an output voltage, which is amplified with an amplifier 10 and taken out as an analog output 13 through a full- wave rectification circuit 11 and an integration circuit 12. Thus, the decrease in the magnetic resistance of an air gap part brings about an effect of raising the torque output sensitivity. The dependence on temperature is the nature intrinsic to magnetic characteristic of the rotating shaft and the dependence of the output sensitivity on temperature decreases with an increase in the magnetic flux flowing through the shaft.

Filed: 1995-02-09
Abstract: PURPOSE: To obtain a small-size, thin, wide-band inexpensive non-contact type IC card by a method wherein an antenna is composed of a conductor formed on a thin plastic film and a U-shaped ground conductor surrounding the conductor. CONSTITUTION: On a surface of a plastic film, a conductor D1 and a ground conductor D2 are formed using conductive ink by screen printing. On the surface, a spacer is laminated, which is a plastic film provided with a relief hole on a position corresponding to an IC and coated with an adhesive on the back surface thereof. Lastly, plastic films each coated with an adhesive are laminated as upper and lower layers for forming a non-contact type IC card. In this manner, since the ground conductor is formed to be flush with the conductor, the band is hardly remarkably reduced in width even in a thin IC card.
