摘要:
In a music information database, music information where music pieces and impression words representing impressions of the music pieces and usable as search words when any of the music pieces is to be searched for is registered for a plurality of music pieces. Information collection section collects, from among various information being provided by information source sites, information usable as music-piece-related search words. Registration section registers the words usable as music-piece-related search words, collected by the information collection section, into the database in association with particular music pieces. In this way, it is possible to construct a music information database which permits a music information search therethrough using impression words representing impressions of a music piece, at low cost without taking much time and labor.

A rotation stabilizing device includes a rotary member rotated around a rotating center axis, an inertia member vibrating in accordance with a change of rotating speed of the rotary member, and a viscoelastic connector for detachably connecting the inertia member to the rotary member. The viscoelastic connector has viscosity and elasticity so as to change form in accordance with vibration of the inertia member. The inertia member is connected to at least one of an outer side and an inner side of the rotary member at a same phase in a direction of the rotating center axis of the rotary member by the viscoelastic connector.

A process for industrially preparing intermediates of aromatic amidine derivatives having anticoagulant activity, i.e., compounds represented by formula (3) or salts thereof, by the following reaction scheme including (1), (2), and (3), wherein R1 represents H or an alkyl group; and R3 represents H, an alkyl group, or an alkanoyl group
摘要:
In a driving apparatus to transmit driving power to an image carrying member in an image forming apparatus, provided with a driving gear and a flywheel coupled with the image carrying member, there are further provided with a rigid protrusion fixed on one of the driving gear and the flywheel; and an elastic member fixed on the other one of the driving gear and the flywheel, the elastic member is shaped so as to engage with the rigid protrusion and includes a first member provided in contact with the rigid protrusion at the engaging portion for elastically deforming itself so as to control a natural frequency value of a driving system including said rotating body, and a second member for controlling damping characteristics of said driving system.

An image forming apparatus having a rotational body. The apparatus includes: the rotating body such as a photoreceptor drum; a driver for driving the rotating body; the first member, provided in a driving transmission path of the driving force, for transmitting the driving force from the driving source to the rotating body, and for elastically deforming itself so as to control a natural frequency value of a driving system including the rotating body and driving source; and the second member, provided in the driving transmission path of the driving force, for controlling damping characteristics of the driving system.
摘要:
A proper frequency of a driving system is shifted to a high frequency side by increasing the rigidity of a photoreceptor drum or the proper frequency of the driving system is shifted to a low frequency side by reducing the rigidity of the photoreceptor drum so that the proper frequency of the driving system is made so as not to conform with a frequency of a speed fluctuation component transmitted to the driving system. With this construction, the photoreceptor drum is prevented from causing the resonance and the speed fluctuation is reduced so that an image quality can be improved.
摘要:
A driving device for a rotational photoreceptor drum for use in an image forming machine, in which a rotational drive from a motor is supplied through a gear train to the axial shaft of the drum. The shaft is connected to the drum only at the side farthest from the gear train. An inertia member is provided within the drum. A rotational member having a rotational resistance is brought in contact with a non-image region of the drum.

A process of shaping a thin metal film into a lead frame starts with preparing a thin metal film, an etchant effective against the thin metal film and a photoresist solution resistive to the etchant, followed by coating the entire surface of the thin metal film with the photoresist solution so as to form a multiple level structure having the thin metal film and a photoresist film, and a predetermined pattern is embossed on the multiple level structure so as to break slits in the photoresist film along the periphery of the predetermined pattern, then removing a part of the multiple level structure by using the etchant so that a hollow space is formed therein in the predetermined pattern.
