Title: Gear changeover device
Inventor: HANIYU TOSHIO
IPC: G11B15/26
Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To make it possible to well mesh the gears of a gear change device with each other when a gear changeover device is shifted to a state of meshing the gears with each other. SOLUTION: The shaft barrel part 100 of the one gear 80 is pivotally supported by forked spindle part 84 and sub-shaft part 92 of a shaft member 78. When the meshing of the gears 80 and 120 with each other is defective, the end peripheral part 102 of the shaft barrel part 100 is disengaged from a positioning part 96 of a head part 92 of the sub-shaft part 86 and the end peripheral part 102 manipulates an inclined guide part to deflect the sub-shaft part 86. The shaft barrel part 100 of the one gear 80 is then elastically deformed in an inclined state with respect to the revolving shaft of the shaft member 78. As a result, the frictional resistance in the portions where the gears are meshed with each other is reduced and the gears are turned with each other in different directions with relatively small torque so that the gear can reset to the state of meshing each other.

Title: Data signal equalization and signal equalizing circuit arrangement
Inventor: MUSUTAFUA KIYUBIREI GAAKAN
IPC: H04B3/06
Filed: 1989-01-06
Abstract: PURPOSE: To improve the performance of DPE expressed by a signal to noise ratio(SNR) and a bit error rate(BER) by inverting the stream of data, supplying the stream inverted data to a discrimination feedback equalizer(DFE) and inverting the stream of discrimination outputted from the equalizer. CONSTITUTION: In the DFE to be operated in a forward data mode or a data invertion mode, a received input signal sample is supplied to a feed forward filter section 16, and its weighted sum is generated. A feedback filter section 18 is driven by discriminating preceding data, and the influence of a preceding symbol upon the current discrimination is eliminated. On a discrimination stage 20, the discrimination is performed based on the value of a signal in an input at a fixed time point. This time point is determined by a reference tap position(RTP) to be used as the symbol of synchronization between a transmitter and a receiver.  When a channel impulse response is almost fixed, the RTP is selected to be the peak of the channel impulse response and when the channel impulse response is changed and the SNR is low, the RTP is arranged at a position where the 1st allowable pulse of a stream attached to the symbol exists.

Abstract: PURPOSE: To measure the position of the measuring objects mounted to a substrate with good performance by making use of the principle of an ultrasonic angle beam flaw detection method.  
     CONSTITUTION: An arbitrary size l 1  from one surface of the measuring object 2b secured by welding 3 to a substrate 1 is determined and a punch hole 11 which becomes a reflection source of ultrasonic waves is opened on the back of the substrate, after which said punch hole 11 is detected by using an angle probe 7 from the front surface of the substrate 1. In the case of the angle probe 7 of 45°, the horizontal distance from the angle probe 7 up to the punch hole 11 corresponds to a plate thickness (t) and therefore l 1 +t is made a reference size. Next, the angle probe 7 is stopped at the point where it has detected the punch hole 11 and the distance l 2  up to the measuring object 2a is obtained. From the difference between l 2  and the reference size l 1 +t, the quantity of dislocation between both plates α is obtained. The use of a measuring jig 12 whose plane and side faces are both of L-form and whose end side end 12a is notched to arc form in measuring the sizes l 1 , l 2  is suitable.

Title: System and method for distributed communication control
Inventor: ISHII KEI
IPC: G06F13/00
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To easily and speedily detect communication abnormality by confirming whether a communication function is recovered or not at every prescribed time, updating the relevant part of table into established state when the recovery is confirmed, and performing communication while alternately using duplexed communication routes. SOLUTION: Each controller 3 transmits the table of communication enable/ disable state to an operator station 1 periodically while using the normal communication route. The operator station 1 displays the table of communication enable/disable state sent from each controller 3 in the table of matrix with a communicating party and presents the part, where the occurrence of any trouble is judged, from the matrix to an operator. Each controller 3 tries communication through the disabled route to the communicating party in disabled state on each route for confirming whether the communication function is recovered or not at every prescribed time. As a result, when communication is made successful, the route is returned to the enabled state and concerning following communication, communication is performed while alternately using the duplexed routes.

IPC: B65H3/06
Filed: 1985-01-09
Abstract: PURPOSE:To make the press-contact forces of feed rollers acting upon on the left and right sides of a paper sheet to be used, substantialy equal to each other, by shifting the gravitational center of the feed roller to a substantially center position in the lateral direction of the sheet with the use of a weight in accordance with the size of paper sheets. CONSTITUTION:A shaft 3 is rotated for every paper feed, and this rotation is transmitted to a feed roller 6. The uppermost paper sheet is separated from the paper sheets subsequent to the second one, since both left and right corners of the uppermost one come off from separating pawls 2, 2 due to the feed-out force provided by the rotation of the roller 6. The thus separated uppermost paper sheet is fed into between guide plates. At this time, a movable weight 10 is slid to left and right along a guide rod 11 to adjust the slide position in accordance with the size of the sheets so that the gravitational center of the feed roller is shifted to a substantially middle point position W' or W'' of a paper sheet to be used in the lateral direction. With this arrangement the press contact forces on the left and right sides of a paper sheet are substantially equal to each other for vaious size paper sheets, and therefore, no oblique feed trouble may be caused, thereby it is possible to feed paper sheets smoothly one by one.
