Title: Ecl circuit
Inventor: TATEHARA KENICHI
IPC: H03K19/08
Filed: 1989-12-28
Abstract: PURPOSE:To realize high speed operation by supplying a charge current through a P-channel MOS transistor(TR) to transfer the level of an output terminal rapidly from an L to an H level. CONSTITUTION:When the level of a noninverting input terminal 6 changes from an L to an H level and the level of an inverting input terminal 7 changes from an H level to an L level, an inverting output terminal 10 is apt to go from H to L and a noninverting output terminal 11 is apt to go from L to H. When the level of the inverting output terminal 10 is lower than the threshold voltage of a P-channel MOS TR 12, the P-channel MOS TR 12 is turned on. On the other hand, since an NPN TR 2 is turned off, the noninverting output terminal 11 is charged by a current being the sum of a current flowing from a ground 8 via a load resistor 4 and a current flowing from the ground 8 via the P-channel MOS TR 12. Thus, the rapid transition of the level of the output terminal from L to H is attained. Thus, high speed operation is made possible.

Title: Antidewing material and tube covering structure using the material
Inventor: OKANO TERUO
IPC: B32B27/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to avoid the various faults due to condensate on the surface of a tube, in the heat insulator of covering the tube or the surface of the insulator by laminating a porous film on the one side surface of a water absorption synthetic resin sheet. SOLUTION: The antidewing material is constituted by laminating a porous film on the one side surface of a water absorption synthetic resin sheet. Accordingly, the condensate on the back surface of a porous film is absorbed via the pores of the film by the water absorption drying force of the water absorption synthetic resin sheet even if the surface tension is large, and water retention is conducted. On the other hand, even if the moisture in the sheet becomes the water retentivity or more due to the temperature rise of the atmosphere so that it is oozed as liquid water on the surface of the sheet, since there is no driving force for discharging it on the back surface via the pores of the film against the surface tension, the liquid water is not discharged at the back surface side. Thus, it can be suitably used even in civil engineering and building fields.

Title: Automated guided vehicle
Inventor: MATSUBA KATSUMI
IPC: G05D1/02
Filed: 1993-12-15
Abstract: PURPOSE:To plan a course avoiding a congested area by introducing the concepts of staying times and the numbers of staying vehicles by zones in a course programming method for an area wherein plural automated guided vehicles move simultaneously. CONSTITUTION:An autonomous AGV1a as an automated guided vehicle moves an initial position S to a target position G while avoiding an obstacle O. The area wherein the autonomous AGV1 other than the obstacle O can move is divided into plural zones Z of proper size. Once the autonomous AGV1a receives such a conveyance request from a host computer that it moves from the initial position S to the target position G, an autonomous controller plans a basic course. Then when the number of other automated guided vehicles which stay at passage scheduled time based upon the obtained basic course is larger than the limit number of vehicles set for each zone, the passage scheduled time is delayed to avoid congestion. Further, when there is a zone wherein the delay time is longer than a specific time, the zone is regarded as an obstacle and the basic course is refound.

Title: Variable displacement swash plate compressor
Inventor: KAZAHAYA YUKIO
IPC: F04B27/14
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent abrasion and seizure of contact parts of a swash plate and a shaft as well as to improve controllability by smoothing the axial motion (the tilting motion) of the swash plate. SOLUTION: Contact pins 63a, 63b, 63c and 63d are always in contact with the outer peripheral surface of a shaft 5. Since the outer peripheral surface of the shaft 5 is always in contact with the contact pins 63b, 63b when a torsion moment acts on a swash plate 60, the edge of a central hole of a swash plate 60 is not brought into direct-contact with the outer peripheral surface of the shaft 5. As a result, the motion (the tilting motion) of the swash plate 60 is smoothed during the operation of a compressor.
