    摘要: A control apparatus for a hydraulically operated vehicular transmission having a plurality of hydraulic engaging elements has an accumulator which is connected in parallel with a hydraulic engaging element for a low-speed transmission train and a back pressure generating source which generates a hydraulic oil pressure to be supplied to a back pressure chamber of the accumulator. The control apparatus includes a changeover valve which can be changed over between a first position in which the back pressure chamber of the accumulator and the back pressure generating source are brought into communication with each other and a second position in which the communication is cut off to lower a pressure in the back pressure chamber. The changeover valve is arranged to be changed over from the second position to the first position when a hydraulic oil pressure in the hydraulic engaging element for the low-speed transmission train has exceeded a predetermined pressure.

    摘要: A control apparatus for a hydraulically operated vehicular transmission has a plurality of hydraulic engaging elements including a first hydraulic engaging element which is kept engaged in a plurality of transmission trains. The control apparatus has an accumulator which is connected, via a branched oil passage, to a working oil passage which is communicated with the first hydraulic engaging element. It also has a control valve which is disposed in the branched oil passage and which can be moved between a first position in which an upstream portion of the branched oil passage on a side of the first hydraulic engaging element and a downstream portion of the branched oil passage on a side of the accumulator are brought into communication with each other and a second position in which the communication is shut off. It further has an oil discharge passage which is connected to a second hydraulic engaging element when the second hydraulic engaging element is disengaged. This oil discharge passage is arranged to be connected to the downstream portion of the branched oil passage in the second position of the control valve.

    摘要: The transmission is of a type that a low-speed transmission train is established in cooperation with one-way clutch. A high-speed transmission train is established by hydraulic oil supply via a shift valve in a condition in which the hydraulic oil is kept supplied to the low-speed hydraulic engaging element. A pressure adjusting valve and a hydraulic oil pressure control valve control, to increase or reduce, the supply pressure of the hydraulic oil to the high-speed hydraulic engaging element. A speed change controller at an initial stage maintains the shift valve, at the time of speed changing from a high-speed transmission train to a low-speed transmission train, in a condition in which the hydraulic oil is supplied to the high-speed hydraulic engaging element. The supply pressure of the hydraulic oil is reduced in this condition until the high-speed hydraulic engaging element gives rise to a slip. The supply pressure of the hydraulic oil is maintained in the condition of reduced pressure until the one-way clutch is engaged and thereafter the shift valve is changed over to a condition in which the hydraulic oil is discharged from the high-speed hydraulic engaging element.

    摘要: An impedance meter includes a floating type ammeter which measures a voltage across a current detection resistor and determines a current flowing therethrough. A balun eliminates the common mode voltage component in the high frequency range; and a differential amplifier eliminates the common mode voltage component in the low frequency range. The common mode rejection (common mode elimination) effect of the balun and differential amplifier crosses over at a crossover frequency where the impedance of an capacitor and the impedance of the balun are equal. As a result, the impedance meter is capable of measuring a broad range of impedances across a wide range of frequencies, both the low frequency and high frequency range.

    摘要: A highly accurate electromagnetic-induction-type conductivity and dielectric constant meter is obtained by using a calibration box (instrument) and a structure as below. The conductivity and dielectric constant meter employs an electromagnetic inductive probe which includes a primary transformer composed of a toroidal core with a wound primary coil, a secondary transformer composed of a toroidal core with a wound secondary coil, an electrostatic shield shielding the transformers, and cables that connect the probe to a meter. To eliminate the electrostatic capacity produced by causes other than electromagnetic induction, the structure of the probe is symmetrical. In a first embodiment, the secondary transformer is placed between two parts of the primary transformer, which has two cores of the same shape that are placed symmetrically. The structure, including the primary and secondary transformers, gaps in the electrostatic shields, and cables, are symmetrical with respect to a plane perpendicular to the central axis of the ring shapes and passes through the center of the annular core of the secondary transformer.
