Title: At-earthquake operation device of elevator
Inventor: HARA YUICHI
IPC: B66B5/02
Filed: 1994-12-20
Abstract: PURPOSE: To make continued operation of elevator temporarily when one earthquake sensor is actuated while another sensor is kept in the working condition. CONSTITUTION: An at-earthquake elevator operating device is equipped with an earthquake sensor 12 of small level actuation and another earthquake sensor 13 of large level actuation, and elevator car 1 is stopped at the nearest floor when the sensor 12 is actuated, and after a certain time, the sensor is restituted automatically to the working condition to resume the elevator operation. When the other sensor 13 is actuated, the car 1 is stopped at the nearest floor, and the elevator operation is ceased.  This at-earthquake elevator operating device incorporates a continuous operation circuit 9 consisting of a terminal unit 16 to receive a continuous operation command from the service station when the sensor 13 is actuated, a failure sensing circuit 18 to judge if it is OK to continue the operation after sensor 13 actuation when the continuous operation command is fed, and a continuous operation command circuit 19 which puts the sensor 13 in working condition if the passed judgement shows a normality and holds a continued operation while monitoring the earthquake generating situation thereafter with the sensor 12.

Title: Discriminating method for inside cusp and outside cusp of polygon
Inventor: SASAKI HIROYUKI
IPC: G06T11/40
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To judge an inside cusp and an outside cusp even when two segments having vertexes as end points overlap each other by discriminating a branch point from a segment formed of forward and backward arrays of dots starting at a noticed vertex when two segments having the noticed vertex as end points overlap each other, and making a judgement from the position relation between two segments passing the branch point. SOLUTION: In the case where vertex p(0) of a polygon is noticed, two sides p(11)p(0) and p(0)p(1) having the vertex as end points overlap with each other, so two sides p(10)p(11) and p(1)p(2) to be compared are updated. Since the two updated sides p(1)p(2) and p(10)p(11) overlap each other, they are updated into short sides p(10)p(11) and p(9)p(10) within the two sides. After the update, since the two sides p(1)p(2) and p(9)p(10) to be compared do not overlap, the external product value of those two sides is calculated and the sign of the external product value and the sign of the signed area of the polygon are compared with each other, thereby making an inside/outside cusp decision on the vertex p0 by using the comparison result.

Title: Method and device for controlling buffer
Inventor: MASUDA MICHINORI
IPC: H04L12/861
Filed: 1989-12-08
Abstract: PURPOSE:To perform the release of a buffer at a time when a response from the communication destination of a re-transmission control part is received by adding a constant value on the in-use counter of the buffer when the re- transmission control part performs packet transmission, and substracting the constant value from the counter when the response for a transmitted packet is received. CONSTITUTION:A data link layer performs protocol processing when a DT(data) packet is received. When the protocol processing is performed at a transport layer, and it is confirmed that the packet is an AK packet for the DT packet transmitted previously, the in-use counter 16 of the buffer of the DT packet held at a numeric value setting means 2 is decremented by one. At this time, a numeric value comparison means 1 compares whether or not the value of the in-use counter 16 is 0, and since it coincides with 0, a list deletion means 4 and a list insertion means 5 release the buffer by moving the buffer from a buffer list 11 in current use to a null buffer list 10. When noncoincidence with 0 is obtained, no buffer is released, and the content of the buffer is held.
