Abstract: PURPOSE:To make it possible to speedily and accurately produce a program for a new test and reduce the number of original test programs needed in testing a semiconductor device by storing set specifications and criterial specifications for different kinds of tests, and reading out one suitable specification. CONSTITUTION:The whole processes have been centralized, and test programs have been stored in a main memory 3 as 4-byte data representing four data: the system register name 9 and test specification data 11 for three processes. In testing, while being successively read out, the test specification data are selected by a specification data selector 8 by using a process selecting switch 7 from the outside and outputted to the tester bus, and a system register 6 is selected by a similar method to conventional IC testers, so that the test specification data can be latched in the register 6. By said constitution, when specifications are alterned, alterations can be made for several processes at a time. In addition, the number of needed original test programs decreases, so that custody thereof is facilitated.

Title: Burst data communication method in tdma system ring type lan
Inventor: YONEDA MITSUO
IPC: H04L12/42
Filed: 1991-03-15
Abstract: PURPOSE:To reduce the wait time even when a multiplex and consecutive burst data is sent with respect to the burst data communication method in a loop type LAN of a time division multiplex (TDMA) system. CONSTITUTION:When a frame header analysis section 20 detects it that a frame number is MF0,SF0, the section 20 discriminates the frame to be a token slot frame and sends it to a token slot analysis section 21. The analysis section 21 informs a node address of a token slot in which a token operating bit is not set to a transmission control section 19' in terms of an address signal. The control section 19' compares the signal with a latched address. When they are coincident, the control section 19' generates a transmission enable signal to be sent to a transmission buffer 14 in a timing of a transmission timing signal from the analysis section 20 when a transmission enable signal representing the detection of an inoperating bit in a header FHD is enable in a data area from an idle area analysis section 22. The buffer 14 gives a burst data to a slot division section 15 upon the receipt of the transmission enable signal, in which the data is divided into slots of the TDMA system LAN and the result is transferred to a frame modification section 24.

Title: Method and device for fault restoration in atm network
Inventor: YOSHIHARA TAKAHITO
IPC: H04L12/28
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To increase the recovery rate of a virtual path VP. SOLUTION: When a faulty virtual path takes place in a line network nodes 2 and 3 in an asynchronous transfer mode ATM consisting of nodes 1-4, a Sender 3 of a path receiver side node broadcasts a reservation message to a Tandem 1 (4) of an adjacent node. The Tandem receiving the reservation message broadcasts the reservation message to an adjacent Tandem 4 (1) furthermore. When the reservation message reaches a Chooser 2 at a path transmitter side node, the Chooser 2 stores the reservation messages received within a prescribed time all as bypass candidates and adopts the bypass candidates for a bypass until a predetermined minim warrant restoration rate is satisfied with respect to a request band of the faulty virtual path. Thus, the faulty virtual path is switched into virtual paths of a plurality of bypasses and restored.

Title: Rolling bearing
Inventor: MUTO YASUYUKI
IPC: F16C33/32
Filed: 1995-03-10
Abstract: PURPOSE: To reduce irrotational synchronous runout by setting a total of even crest components so as to be smaller than a total of odd crest components, of crest components of waviness existing at the rolling surfaces of respective rolling elements. CONSTITUTION: A plurality of rolling elements 5 are provided so as to roll freely for free relative rotation between an outer ring raceway track 2 and an inner ring raceway trick 4. At the respective rolling surfaces of the rolling elements 5, micro- waviness exists. In the case of even number of crests in waviness, both the ends of the diameter of the rolling element are positioned at the top or bottom of the waviness at the same time, so a difference between the diameter formed by connecting the summits of the waviness and the diameter formed by connecting the bottoms of the waviness increases. In the case of odd number of crests in waviness, when one end of the diameter of the rolling element is positioned at the summit of the waviness, the other end is positioned at the bottom, so that a diametrical difference hardly exists.  By selecting the rolling element where a total of even crest components is smaller than that of odd crest components in the waviness of the rolling element from a plurality of rolling elements, and incorporating it, it is possible to improve vibrating characteristics.
