Title: Intra-station loopback test system in loop network
Inventor: NAKAI SHOICHIRO
Filed: 1985-11-21
Abstract: PURPOSE:To attain a transmission/reception test of both the priority control and the transmission right acquisition control furthermore, the dynamic test of both controls by providing the 1st switch inserted in series with the transmission line, a transmission buffer, a control section applying both the controls, a reception section receiving a signal addressed to its own station and the 2nd switch to each node. CONSTITUTION:In conducting the operation test of the transmission/reception control in its own station, a transmission control section 16 controls switches 11, 12 so that a signal from the upperstream device is bypassed toward the down stream and inputted to a control section and a reception section. In this state, the control section stores the test packet addressed to its own station to a transmission buffer section 15. The control section discriminates whether or not the transmission of the test packet is enabled according to the priority control and the transmission right acquisition control and when enabled, the control section gives a transmission command to the said packet to the buffer 15 to change over the switch 12 thereby inputting the said packet to the control section and the reception section for the said test. In the test above, the operation test of the transmission right acquisition control is attained. Further, in using a trigger signal or a polling signal as the test packet, the operation test of the priority control is conducted.

Title: Magnetic disk device
Inventor: EDAKAWA KENJI
IPC: G11B19/20
Filed: 1990-09-28
Abstract: PURPOSE:To effectively reduce thermal off-track by differenciating each relief angle theta of the bearing housings of both ends of a spindle. CONSTITUTION:The angle theta of run off 12 provided on bearing housings A13 and B14 which are attached to both ends of a shaft 3 is differenciated between the bearing housings A13 and B14. When the holes on a base plate 8 in which the outer wheels of the bearing housings enter are expanded to a constant degree due to a change in temperature, since a load is added to the run off part 12 by a radial spring 9 from the opposite direction from the run off part 12, and because the angle theta of the run off part 12 is different, the amount of displacement in the center of the shaft 3 is different between the side of the bearing housing A13 and the side of the bearing housing B14. Using this difference, the inclination of the spindle is corrected. Thus, the inclination of the spindle due to the change in temperature is corrected and the thermal off-track is reduced.

Filed: 1994-09-30
Abstract: PURPOSE: To speedily process exact reading work by deciding the line of characters with kanas printed alongside (agate characters) in an opposite order from a line preceding to the final character line and deciding that the final character line and the character line preceding to the agate character line are not the agate character line. CONSTITUTION: Concerning the character lines stored in a storage part, whether it is the agate character line or not is decided in the direction of an arrow instructed by a code R oppositely from a character line L4 on the lowest stage to a character line L1 on the upper stage. When any character line is decided as the agate character line, that information is added to the storage part. Thus, the respective line are decided in reverse order R but since no agate character line comes to the final character line containing a character positioned at the end of each sentence, namely, to the final stage L4 of the sentence, the final character line L4 is processed as it is not the agate character line without receiving the agate deciding work.  Besides, since the agate character line is not continued for two line, a character line L2 preceding to a character line L3 decided as the agate character line is decided as a main character line without receiving the deciding processing work.

Filed: 1993-10-20
Abstract: PURPOSE:To provide a solid electrolytic capacitor excellent in reliability wherein conductive high-molecular compound is applied to solid electrolyte, and imperfection due to increase of leak current when a voltage is applied for a long term is little. CONSTITUTION:Conductive high-molecular compound 3 covers a dielectric oxide film 2 so as to leave cavities 7 as oxygen supply sources in fine holes forming the surface of a sintered body (tantalum 1).
