Title: Vibro-isolating device for rotary unit
Inventor: AOKI TAKATERU
IPC: F16F15/02
Filed: 1983-10-26
Abstract: PURPOSE:To both reduce wearing of a thrust rolling bearing and prevent a decrease of vibro-isolating action, by urging a movable unit in an upper direction by springs so as to reduce a load applied to the thrust rolling bearing. CONSTITUTION:An oil tank 1 fixes to its internal wall surface, positioned in the upper of a movable unit 4, a stationary plate 21, and its bottom surface is oppositely faced to the upper surface of the movable unit 4, forming a fine clearance Q generating damping force between the movable unit 4 and the stationary plate 21. Then coil springs 22 are arranged in recessed parts oppositely provided to the upper surface of the movable unit 4 and the bottom surface of the stationary plate 21, and tensile force of these springs 22 urges the movable unit 4 in the upper direction. In this way, a load applied to a thrust rolling bearing 8, comprising ball members 11 and spacers 9, 10 or the like, can be substantially reduced.

Title: Data management system and icon display device
Inventor: IKEDA NOBUYUKI
IPC: G06F3/0481
Filed: 1994-08-25
Abstract: PURPOSE: To provide a user interface that can have a natural access to a data base or a file system by using a storage, a visualization means and a display device. CONSTITUTION: A visualization means 50 visualizes the data which are stored in a storage means by the fixed timing into a three-dimensional object. The application of the fixed timing is due to a fact that the size of the three- dimensional object is subject to the quantity of data. The three-dimensional object that visualized by the means 50 is stored in a three-dimensional object storage means 51. When a display request is received, the three-dimensional object is read out of the means 51 and show on a display device 2. Therefore the period when the display request is received and the three-dimensional object is displayed is approximately equal to the period when the data are read out of the storage. Thus there is no requirement to wait for the processing time of the means 50 for display of the three-dimensional object.

Title: Measuring system for residual amount of tape
Inventor: KUBOTA KAZUYUKI
IPC: G11B15/03
Filed: 1981-12-16
Abstract: PURPOSE:To measure the residual amount of a tape with high precision by detecting the revolving angle A of the reel drive disk of one side while either one of the reel drive disks of supply and take-up sides turns by a certain angle H, and measuring the speed of revolution of the disk with a variable related to both reel drive disks of the supply and take-up sides respectively. CONSTITUTION:The disks 1 and 2 are attached coaxially with reels 3 and 4 of the supply and take-up sides respectively, and holes are drilled to these disks with a certain  angle respectively. When a switch 9 is turned on, a gate 10 is turned on for the first time at a time point when a phototransistor (PT)8 is turned on, i.e., when a hole 2-1 or 2-2 of the disk 2 passes through. Then a counter 12 is fed to a reset terminal. At the same time, an FF11 is turned on at a moment when the PT8 is turned on, and the ON state of the FF11 is kept until the PT8 is next turned on. The chip enable of the counter 12 is kept on while the FF11 is turned on. Thus the counter 12 works to count the ON/OFF pulses which are so far supplied to a terminal IN consecutively to obtain a pulse number N. The residual amount of the tape is obtained from the number N. The detection of this residual amount of tape can be performed with more improved precision as the tape approaches to the end by increasing H of the take-up side and at the same time decreasing of the supply side respectively.

Filed: 1988-08-12
Abstract: PURPOSE:To reduce the size and eliminate a loss during the sheet carrying by providing a sheet reversing means on the sheet carrying direction downstream side of a refeed carrying route so that the reversion of the sheets in the sheet reversing means can be carried out nearly within the projected area of the paper feed means. CONSTITUTION:To record images on the both sides of a sheet S, the sheet S having a record on the first surface is again sent into a process unit (image recording part) 3 through a reversed carrying route (refeed carrying route) 13c while it is reversed by a switch back part (sheet reversing means) 14. In this case, as the reversion of the sheet S is carried out nearly within the projected area, no space for reversion is required to provide horizontally. Also, as the switch back part 14 is provided on the sheet carrying direction downstream side of the reversed carrying routes 13a-13c, in a double-face recording to a plurality of sheets, the second sheet can be recorded at a determined interval and introduced to the reversed carrying route 13a-13c even when the first sheet is stopped for refeeding.

Title: Bypass route selection system
Inventor: KIMURA JUNICHI
IPC: H04L45/24
Filed: 1989-08-02
Abstract: PURPOSE:To prevent the communication faults by sending a new communication request to a bypass route when the relay line of the shortest route has a fault and requires a bypass route and furthermore the transmission quality is degradated down to a prescribed level or less. CONSTITUTION:A relay line quality monitoring function part 402 disables the relay of the selection display data on the relay lines contained in a relay line selection display memory table 405 when the transmission quality of the relay line is degradated less than an allowable level. A relay line selection function part 406 decides a relay line 300 that is defined as the shortest route to a terminating station 201 and then takes the selection display data out of the table 405. Then the part 406 selects a bypass route relay line 301 to connect this to a switch circuit 407 in place of the line 300 when the display data has a fault and kept in a relay unable state. Thus it is possible to prevent such a state where the data transmission quantity is degradated and the flow of data is disturbed.
