    • This invention relates to a pressure reducing valve wherein a spool is driven axially by a first plunger which moves according to the magnetization state of a first solenoid, and a control port is connected to a supply port and a tank port according to the axial position of this spool. The pressure of the control port acts on the spool in the opposite direction to that of the plunger via a feedback passage, and the pressure increases or decreases according to the current flowing through the first solenoid. According to this invention, a second plunger is arranged in series with the first plunger, and a spring tends to push the second plunger toward the first plunger. A second magnetized solenoid however keeps the second plunger held back against the restoring force of the spring so that it is not in contact with the first plunger, and releases the second plunger so that it pushes the first plunger when the current fails. Hence, even if the current supplied to the first and second solenoids is cut off, the control port maintains the predetermined pressure, and a fail-safe mechanism is realized by means of a simple construction.

    • A charged-particle beam system capable of reliably detecting defects in an interconnect pattern, which is formed, for example, on a semiconductor device. The system uses an electron source for producing an electron beam. A specimen on which the interconnect pattern is formed is scanned with the electron beam in two dimensions. An image of the specimen is created based on a signal obtained from the specimen in response to the scanning, and the image is displayed on a display portion. Two probes are brought into contact with arbitrary locations on the interconnect pattern. Absorption currents obtained via the probes are applied to a differential current-voltage converter. Thus, the difference between the absorption currents is converted into a voltage signal. An absorption current image is created based on the voltage signal and displayed on the display portion.

    • An active torque-split control system for actively controlling a distribution of driving torque applied to front and rear wheels in a four-wheel drive vehicle employing a transfer device including a transfer clutch for varying said driving torque distribution depending on the operating state of the vehicle, comprises sensors for monitoring the operating state, and a torque-split controller for switching from a normal torque-split control mode to a rigid torque-split control mode only when the controller determines that the vehicle is operated in a warning region closer to a critical state. The normal torque-split control mode corresponds to a first mode that the rear-wheel driving torque gets priority over the front-wheel driving torque, while the second controllable torque corresponds to a second mode that the transfer ratio of the front-wheel driving torque is quickly increased to be substantially equal to that of the rear-wheel driving torque so as to obtain a front-wheel speed substantially equal to a rear-wheel speed.

    • A method of producing a monolithic three-way catalyst for the purification of exhaust gases of internal combustion engines. First, a mixed oxide coating is provided to a monolithic carrier by treating the carrier with a coating slip in which an active alumina powder containing cerium in oxide form is dispersed together with a ceria powder and then baking the treated carrier. Next, Pt, Rh and/or Pd are deposited on the oxide coating by a known thermal decomposition process. The addition of the ceria powder to the coating slip is effective in enhancing the CO, HC and NO.sub.x conversions and durability of the produced catalyst at high temperatures. Preferably the content of Ce in the active alumina powder is 1-5 wt %, and, in the coating after baking, Ce of the ceria powder amounts to 5-50 wt % of the coating. Optionally a zirconia powder too may be added to the coating slip such that Zr of the zirconia powder amounts to 1-10 wt % of the coating.

    • A torque split control apparatus for use with an automotive vehicle including an engine for producing a drive. The automotive vehicle is supported on a pair of primary drive wheels and a pair of secondary drive wheels. The drive is transmitted from the engine to the primary drive wheels and to the secondary drive wheels through a torque distributing clutch capable of varying a torque transmitted to the secondary drive wheels. A control torque is calculated based upon a difference between the primary and secondary drive wheel rotational speeds. The control torque is transmitted through the torque distributing clutch to provide a desired turning characteristic to the vehicle. At least one vehicle condition dependent torque, which is dependent on a specified vehicle operating condition, is calculated. Vehicle operating conditions are monitored to produce a command signal when a 4WD control is demanded. The control torque is selected in the absence of the command signal and a greater one of the control torque and the vehicle condition dependent torque is selected in the presence of the command. The torque distributing clutch is controlled to transmit the selected torque to the secondary drive wheels.
