IPC: G06F17/30
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To prevent desired data from being omitted from candidate data during the time of narrowing-down work when a key word used for retrieval is not casually made to correspond to the data yet by adding a repechange type AND retrieval function. SOLUTION: A natural number (n) larger than 2 is previously set and the i-th retrieval process is carried out by a retrieval means. If i<=n is defined under such conditions, the AND sets of (i) pairs of relative sets, which are extracted in the 1st to i-th retrieval processes are decided as candidate sets. If i>=n is defined, the AND sets of (n) pairs of relative sets which are extracted in the (i-n+1)-th to i-th retrieval processes are decided as candidate sets respectively. Then the nodes belonging to those decided candidate sets are shown as the candidate nodes. In other words, the node N0 that is omitted from the candidates at an AND part, i.e., (G1) AND (G2) AND (G3) AND (G4) revives as the final candidate via an AND part, i.e., (G2) AND (G3) AND (G4).

Title: Vehicle collision preventing device
Inventor: HASHIMOTO YOSHIYUKI
IPC: B60R21/00
Filed: 1993-02-04
Abstract: PURPOSE:To alarm a collision corresponding to the traveling situation of a vehicle. CONSTITUTION:A detector 10 detects both the speed of the vehicle A entering an intersection and the time of passing the detector 10. Then the detected data are transmitted to a vehicle B passing in front of a transmitter/receiver 12 by way of the transmitter/receiver 12. The vehicle B obtains the intersection entrance probability of a driver's own vehicle B from both the intersection appearance probability of the vehicle A and the vehicle speed and the entrance acceleration of the driver's own vehicle B. Then, collision probability distribution is obtained from the intersection entrance probability of both vehicles. Consequently, only when collision probability is large, a collision avoiding operation such as alarming, etc., can be executed so as to effectively prevent the collision.

Abstract: PURPOSE:To make variable the heat-insulating performance of a container, consisting of a container main body which has a double-wall filled with a filler and evacuated inside and a lid, by adjusting the fittingness of a lid on the container main body according to an inside temp. CONSTITUTION:A container main body 1 and a lid 2 are made up of exterior and interior walls made of austenite stainless steel. The closed spaces between the exterior and interior walls are evacuated and filled with silica fine powder to form a composite heat-insulating layer. The lid 2 is formed into a cap-like shape, and its circumferential wall 3 is lower than the height of a fitting shoulder part 4 around the circumference of a top opening of the container main body 1 so that the lid 2 is lightly fitted on the fitting shoulder 4. When the inside of the container main body 1 becomes high- temperatures, the thermal expansion of the interior wall of the lid 2 becomes larger than that of the exterior wall. Therefore, as the interior wall of the lid 2 that is fixed by a post 5 in the middle warps upward along the circumference. As a result, a small gap is produced in the fitting part between the lid 2 and the container main body 1 to allow the heat inside the container main body 1 to escape outside, so that the heat-insulating performance of a heat-insulated container can be automatically reduce.

Title: Twisting and spinning
Inventor: MATSUSHIMA AKIO
IPC: D01H7/90
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To obtain a spun yarn having an approximately constant appearance and approximately constant physical properties by increasing the rotation rate of a twisting roller to enhance a twisting force, when a spun yarn tension detected at a twisting and spinning time reaches a prescribed lower limit value. SOLUTION: A sliver S drafted with a draft device D is fed into a twisting device T equipped with a twisting roller through a spinning nozzle N to produce the spun yarn Y. In the process, the tension of the spun yarn Y is measured using a tension-detecting device 9, and the detection signal is inputted into a central controller 10 which can arbitrarily set the rotation rate of the twisting roller. When the tension value reaches a prescribed lower limit value, the central controller 10 outputs a signal to a motor-driving controller 11 to increase the rotation rate of the twisting roller so as to maintain the twisting force. When the rotation rate of the twisting roller reaches the upper limit, the spinning operation is stopped. Thus, the spun yarn Y having a prescribed strength can always be produced.

Abstract: PURPOSE:To attain an access to the data in the same timing as a case where no error is detected by outputting the data corrected by a correction means via a switch means only when an error bit is included in a data bit part and transmitting a correctable error production signal via a report means. CONSTITUTION:When a read address 107 is received in a cycle T1, the data on a designated address of a memory module 3 is held by a read data register RDR 4 in a cycle T2.
