摘要:
A hydraulic pressure control valve comprises a valve body having a slide bore of a circular cross-section and an inlet port and an outlet port opened into an inner surface of the slide bore at axially spaced apart points, and a valve spool slidably received in the valve body for axially sliding movement and defining, by cooperation with the valve body, a variable orifice for controlling the degree of communication between the inlet and outlet ports. In the hydraulic pressure control valve, a smaller diameter portion defining an annular oil passage between an inner surface of the slide bore is provided on the valve spool coaxially with the slide bore to define the variable orifice, and has an outside diameter set constant over axially entire length. This facilitates the dimensional control of the variable orifice, so that the variation in property of the variable orifice for every hydraulic pressure control valve may be easily suppressed.

摘要:
A process of producing a ring-opening polymerization product of a norbornene derivative containing at least one polar group or aromatic group, a norbornadiene derivative containing at least one of said groups or a cycloolefin using a catalyst system prepared from an organometallic compound and the reaction product of tungsten oxide or molybdenum oxide and a phosphorus pentahalide or phosphorus oxytrihalide or these compounds and other third components. The catalyst system possesses a high polymerization activity.
摘要:
A control system for an internal combustion engine that performs learning of a throttle opening degree during idle operation, at which a target idle speed can be obtained, the control system comprising a control section that is configured to use a first learned value and a second learned value as learned values of the throttle opening degree during idle operation and to update the first learned value when a state of combustion is not deteriorated, and update the second learned value when the state of combustion is deteriorated.
摘要:
A controller executes an engine intermittent operation to stop operation of an engine when a given engine operation stop condition is satisfied and to start the engine when a given engine start condition is satisfied, makes an in-cylinder injection valve abnormality determination while causing a total amount of fuel to be injected from the in-cylinder injection valve, and makes a port injection valve abnormality determination while causing the total amount of fuel to be injected from the port injection valve. The controller inhibits execution of the engine intermittent operation until the in-cylinder injection valve abnormality determination has been made and the port injection valve abnormality determination has been made.
