Title: Elevator doorway device for base-isolated building
Inventor: UGAWA KIMITAKE
IPC: B66B13/30
Filed: 2002-11-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide an elevator doorway device for a base-isolated building where a doorway between both a base access and a shaft access normally responds to the displacement between both of them when a shaft leans.  <P>SOLUTION: A doorway 7 with no gap in floor surfaces, wall surfaces and ceiling surfaces in a normal condition is formed to achieve a good appearance. During earthquake, or the like, a fixed-side upper blocking plate 32, a fixed-side lower blocking plate 39, a shaft upper blocking plate 46 and a shaft lower blocking plate 49 are slid and displaced from their opposed members via guides 38, 45, 48, 51 formed of members having low friction performance. Thus, both the blocking plates and the guides are smoothly slid and displaced during relative displacement of a base building 2 and a base-isolated building 4, therefore avoiding inconveniences including deformation of both of them with slide and displacement and incomfortable squeak noises.  <P>COPYRIGHT: (C)2004,JPO

IPC: G11B20/12
Filed: 2002-11-08
Abstract: <P>PROBLEM TO BE SOLVED: To substantially shorten data recording time even if a host information processor requests recording of data which does not keep to a block size (boundary), while suppressing reproduction operation for generating an error correction code to the minimum.  <P>SOLUTION: A information recording and reproducing apparatus is equipped with a central processing unit 34 which monitors a data recording request from a host computer and also determines whether or not the data being requested to be recorded by the computer concerned is consecutive to the data to which recording operation is being carried out. When the data requested to be recorded by this computer is consecutive to the data under recording operation, the data is collectively recorded on the magnetic disk 18. When a second block of the data requested here to be recorded is made a unit and the last block does not fill a block size, the data wherein the second block is a unit is separated from the data requested to be recorded, and the next sequential recording request from the computer is waited for predetermined time.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a digital trimming system capable of omitting a connecting terminal required between a device to be trimmed and a trimming device and capable of miniaturizing the profile of a product.  <P>SOLUTION: A predetermined frequency clock signal produced by an internal clock producing means is converted from a voltage fluctuation into a current fluctuation in the side of the device to be trimmed and, thereafter, the signal is transmitted to the trimming device through a power supply inputting terminal in the device to be trimmed and a power supply outputting terminal of the trimming device side. In the side of the trimming device, the current fluctuation from the device to be trimmed is read to convert the same into the voltage fluctuation. Further, the voltage fluctuation is shaped into the clock signal as the reference clock signal of the trimming system.  <P>COPYRIGHT: (C)2004,JPO
