摘要： Provided is a driving system for a vibrating type actuator capable of simplifying a driving circuit. A vibrating body of the vibrating type actuator can generate a first mode and a second mode which are different in a vibration form, in accordance with an alternate current signal to be supplied. An alternate current signal having a frequency close to a resonance frequency in the first mode or the second mode is applied either between an electrode Va and a common electrode Vc or between an electrode Vb and the common electrode Vc of the vibrating body of the vibrating type actuator. One of the electrodes to be supplied with the alternate current signal is selected by a switching element operated based on a signal from a driving direction switch.

摘要： A vibration-type driving device comprises a vibration element including a driving member and an electro-mechanical energy conversion element having an electrode and arranged to displace the driving member with a driving signal supplied to the electrode, and a driven element that is kept in contact with the driving member of the vibration element. According to the driving signal supplied to the electrode of the electro-mechanical energy conversion element, the vibration element excites vibrations in two flexural vibration modes in which a direction of generation of a node in one mode is perpendicular to that in the other mode. With the use of the two flexural vibration modes, the natural vibration frequency of the vibration element can be prevented from increasing, and the position of a node occurring in one flexural vibration mode and the position of an antinode occurring in the other flexural vibration mode can be made to coincide with each other, so that the amount of displacement of the driving member can be made large.

摘要： In a document retrieval system for retrieving a document from documents stored in storage devices according to a retrieval condition input by a user, the storage device where a retrieval is carried out is selected from the storage devices, and the retrieval condition is input. In the selected storage device, when the retrieval according to the input retrieval condition is carried out, based on a retrieval result, information indicating the number of documents satisfying the retrieval condition is managed for each storage device where the retrieval is carried out. When the retrieval condition is input, based on the managed information, whether the number of documents stored in any selected storage device and satisfying the input retrieval condition is larger than a predetermined number is determined before carrying out the retrieval. As a result of this determination, control of whether to conduct the retrieval is achieved.
