    • The speed of a disc handling operation by a disc apparatus having disc changer capability is significantly increased and, at the same time, the disc handling operation is performed with stability. In the disc apparatus according to this invention, a plurality of reproducing units loaded with discs are moved independently and disc reproduction is started by returning the reproducing units to their dedicated positions. Simultaneous returning of the plurality of reproducing units is prevented and each reproducing unit moves for refuge while reproducing the disc. This novel setup significantly shortens the time for moving the reproducing units for disc reproduction. When continuously reproducing a plurality of discs accommodated in proximity, the plurality of reproducing units are moved in a stacked state rather than independently. This also contributes to a significant reduction of the time in the disc handling operation. Further, when raising the lower reproducing unit in the stack, it is moved together with the upper reproducing unit; when raising the upper reproducing unit, it is separated from the lower reproducing unit for independent movement. This prevents the reproducing units from colliding against each other. The novel constitution significantly enhances ease of use of the disc apparatus.
    • 通过具有换碟机能力的盘装置​​的盘处理操作的速度显着增加,并且同时执行盘处理操作。 在根据本发明的光盘装置中,装载有光盘的多个再现单元被独立地移动,并且通过使再现单元返回到其专用位置来开始盘再现。 防止多个再现单元的同时返回,并且每个再现单元在再现盘时移动避难。 这种新颖的设置显着地缩短了用于盘再现的移动再现单元的时间。 当连续地再现容纳在接近的多个盘时,多个再现单元以堆叠状态而不是独立地移动。 这也有助于在盘处理操作中显着减少时间。 此外,当升起堆叠中的下再现单元时,它与上再现单元一起移动; 当升起上再现单元时,它与下再现单元分离以进行独立运动。 这防止再现单元相互碰撞。 该新颖的构造显着提高了盘装置的易用性。

    • A hierarchical manager-agent structure has upper and lower layers in an open system having OSI standard protocol specifications. The upper layer has an upper-layer manager, an upper-layer agent, and managed objects, and the lower layer has a lower-layer manager, a lower-layer agent. If an operation requested from an upper-layer manager and effected on a managed object in an upper layer by an upper-layer agent affects a managed object in a lower layer, or if an operation reported from a lower layer agent to a lower-layer manager affects a managed object in an upper layer, then corresponding managed-object instances between the upper and lower layers and their operations are converted by a managed-object correspondence information converter based on information stored in a managed-object correspondence information database. The managed-object correspondence information converter has a common interface with respect to both the upperlayer agent and the lower-layer manager.
    • 分层管理器代理结构在具有OSI标准协议规范的开放系统中具有上层和下层。 上层具有上层管理器,上层代理和被管理对象,下层具有下层管理器,下层代理。 如果上级管理者请求的操作并通过上层代理对上层管理对象进行影响,则影响较低层的被管理对象,或者从较低层代理向较低层报告的操作 管理者影响上层的被管理对象,然后基于管理对象对应信息数据库中存储的信息,通过管理对象对应信息转换器转换上层和下层之间的对应管理对象实例及其操作。 管理对象对应信息转换器具有关于上层代理和下层管理器的公共接口。

    • An engine rotating speed sensor detects intake sound information due to the drive of an engine. A controller generates a signal having a frequency corresponding to a desired ratio of orders based on the detected intake sound information. Further, a phase and an amplitude the signal are controlled, and so a speaker arranged in a propagation path of the intake sound of the engine generates control sound to control the intake sound due to the drive of the engine. An engine noise control apparatus which is capable of effectively reducing or waveform-reshaping a wide range of engine noise. The apparatus has an engine rotating speed sensor for detecting an engine rotating speed and a waveform generator circuit for converting a rotation pulse signal to a periodic signal having a frequency which is a predetermined multiple of the detected engine rotating speed. The output of an air flow meter is passed through a bandpass filter and a reshaping circuit to generate a control signal which is an average value of alternating current components of the output. A CPU, with reference to a map previously stored in a memory, modifies the phase and amplitude of the periodic signal with respect to an engine rotation reference signal based on the rotation pulse signal and the control signal, and outputs the modified signal as driving signals to operate speakers disposed in an intake tube and an exhaust tube for reducing noise.
