摘要:
In an engine in which a lift amount of a valve can be changed continuously, an engine valve operating system including a valve lift-changing mechanism is capable of increasing and decreasing the lift amount of the valve without changing an opening angle for the valve and capable of decreasing a tappet clearance in accordance with a decrease in lift amount of the valve. Thus, it is possible to prevent the ratio of the tappet clearance to the lift amount at a low valve lift from being increased to minimize the influence of the dispersion of the tappet clearance and to reduce the seating speed of the valve at the low valve lift to prevent the generation of a noise. It is also possible to prevent a reduction in performance of the engine at a high valve lift due to the dispersion of the tappet clearance and to decrease the seating noise of the valve at the low valve lift.

The present invention relates to a microwave chemical reaction apparatus characterized by comprising a means for heating a reaction liquid, which is capable of irradiating microwaves while controlling the output power according to the temperature of the reaction liquid, together with a means for forcibly cooling the reaction liquid from the outside, and being capable of precisely controlling the reaction temperature. The microwave chemical reaction apparatus can control the reaction temperature precisely, for example, within ±1° C. of a predetermined temperature, and can be applied to fine chemical reactions. Further, since reactions proceed rapidly in such an apparatus, mass production can be achieved by a relatively small-sized reaction apparatus.

Two data centers located in the vicinity are connected using a synchronous transfer copy function, and one of the data centers is coupled with a third data center disposed at a remote location by an asynchronous remote copying function. The order whereat a storage sub-system located in the vicinity has received data from a host is consistently guaranteed, and the third data center holds the data. Further, each storage sub-system includes a function whereby, during normal operation, data can be exchanged and the data update state can be obtained by the storage sub-systems located in the two data centers that do not directly engage in data transmission.
摘要:
A primary controller operates to transmit write data and a write time to a secondary controller in the earlier sequence of the write times after reporting a completion of a request for write to a processing unit. The secondary controller stores the write data and the write time transmitted from the primary controller in the cache memory. At a time, the secondary controller stores the write data in a disk unit in the earlier sequence of the write time. These operations make it possible to guarantee all the write data on or before the reference time.

A combustion pressure detecting apparatus is provided for improving a combustion pressure detection accuracy. The combustion pressure detecting apparatus is mounted in a mounting hole of a cylinder head together with a combustion device for detecting the pressure within a combustion chamber as a combustion pressure. The combustion device may be one of an injector for injecting a fuel and a spark plug for igniting an air/fuel mixture within the combustion chamber. The combustion pressure detecting apparatus comprises an injector seat facing the combustion chamber and arranged in the mounting hole in a state in which a load from the combustion device is blocked, and a sensor element fixed between injector seat and the cylinder head by the injector seat for detecting a load transmitted thereto through the injector seat as a combustion pressure.

With the purpose of achieving consistent non-synchronous copying of data from a plurality of primary side control units to a plurality of secondary side control units, all of the secondary side control units are connected via a loop, and each of the secondary side control units determines guarantee time by circulating a time added to the data received from the primary side control units via said loop communication route. A consistent data copying is guaranteed by circulating the determined guarantee time via the loop communication route.
