Title: Outside handle
Inventor: SATO KIKUO
IPC: E05B1/00
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To provide an outside handle capable of surely preventing a door from opening even if rotating moment is caused around a rotating shaft in an unlocking direction by acceleration operating on a handle during side collision, and achieving its lighter weight while ensuring safety. SOLUTION: An open rod 5 having an unlocking function is connected to a handle to be rotated around a rotating shaft 2 and a damper 10 is provided for granting resisting force to the handle to be rotated in an unlocking direction. The damper 10 includes an air damper connected to one end of the handle for generating counter torque on the handle to be rotated in the unlocking direction. The damper 10 has a piston reciprocating in a cylinder and an orifice formed in the piston. The resisting force of the damper operates substantially as much as a counter weight does to surely prevent a door from opening during side collision.

Title: Semi-rigid joint structure in square steel-pipe column and steel beam construction
Inventor: SASAKI SATOSHI
IPC: E04B1/24
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To increase elastic limit deformation and permanent limit deformation of a framework and improve strength and deformation characteristic of a column member by forming a step part between the height where the beam flange of a steel beam mates with the column member and a diaphragm formed inside the column member, and jointing both of them to a square steel-pipe column. SOLUTION: A step (x) is formed between a beam flange 1 and a horizontal diaphragm C disposed at a column end, and a square steel-pipe column A is jointed to a steel beam B to prevent buckling of a column flange plate through the horizontal diaphragm C. If horizontal load H acts on a framework, a column beam connection part is deformed like a deformation mode F for semi-rigid joint structure, therefore, a column and beam connection part can be deformed in addition to the column A and the beam member B, thereby increasing the elastic limit deformation and permanent limit deformation of the framework. A column member end and the horizontal diaphragm C effects reinforcing, thus it is possible to prevent local buckling of the column member end part and improve strength and deformation characteristic of the column member.

Title: Aligner, and method and device for detecting pattern
Inventor: SUGIYAMA HIDEJI
IPC: G03F7/20
Filed: 1990-08-29
Abstract: PURPOSE:To compensate the background of an alignment pattern signal effectively by irradiating the alignment pattern in the shape of a diffraction grating and the standard pattern in the shape of a diffraction grating, which has substantially the same interval between gratings, respectively with light, and detecting the higher-order diffracted light being obtained from respective patterns, and comparing the signals.

Title: Inverter device
Inventor: HIROSE KENJI
IPC: H02P27/06
Filed: 1987-09-10
Abstract: PURPOSE:To effectively prevent an overcurrent and to rapidly accelerate a motor by detecting that a negative load is operated at the time of an acceleration mode. CONSTITUTION:Output overcurrent detecting means detects the output overcurrent of an inverter at the time of an acceleration mode. Since a microcomputer is a positive load when the polarity of the current of a DC bus is positive, an output frequency is reduced (in step Sb) similarly to a conventional inverter, and output (in step S5). When the polarity of the current of a DC bus 9 is negative, it is negative load. Accordingly, its output frequency is raised (in step S8), and output (in step S5). Thus, the output frequency is rapidly brought into coincidence with the speed of the rotor of the motor to suppress an output current, thereby preventing an overcurrent at the time of negative load.

Abstract: PURPOSE:To aim at improvements in loading capacity and sailing stabilization, by setting height of the hull center of a center tank and height of an inner bottom plate of a wing tank and a longitudinal bulkhead dividing these tanks down to the specified value each, and making the inner bottom plate and the hull form so as to be tilted up toward both sides of a ship. CONSTITUTION:Longitudinal bulkheads 3 and 2 at symmetrical broadsides of the hull 1 are erected in separating from the smaller side than ship width B/5m (B is to be ship width) or 11.5m from side platings of these broadsides. Next, an inner bottom plate 11 in and around the hull center of a center tank 9 is set to less than the smaller side than B/15m or 6m in height from a base line 13, and an intersection point of these longitudinal bulkheads 2 and 3 and the inner bottom plate 11 and the inner bottom plate 11 equal to each bottom plate of wing tanks 7 and 8 are set to be larger than the smaller side than B/15m or 6m in height from the base line 13, while each bottom surface of the center tank 9 and these wing tanks 7 and 8 forms an upward tilt toward both sides of a ship with the hull center as the lowest part, and a ship bottom form is also made to go along this upward tilt. Thus, a sectional area of a double bottom becomes smaller, whereby hull weight is reducible so that loading capacity for a cargo is improved and, what is more, sailing stability becomes increased.

Title: Method and device for preventing backlash of driving device
Inventor: AIHARA HIDEHIRO
IPC: G05B19/18
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To automatically detect the backlash amount of a driving device and to automatically correct the backlash amount so as to prevent machining failures. SOLUTION: The amount of backlash occurring between the ball screw 15 and a ball of a driving device 21 or between a ball nut and a nut member 17 is detected by an acceleration sensor 31 as a rattling amount detector. In a control unit 33, when the detected backlash amount exceeds a preset upper limit value S (threshold value), a backlash amount correction parameter is rewritten so as to keep the backlash amount within the upper limit value. After a servo motor for rotary-driving the ball screw 15 based on the rewritten backlash amount correction parameter is subjected to sudden acceleration, a speed is reset to a normal speed. If the detected backlash amount does not exceed the upper limit value, then no rewriting is performed for the backlash amount correction parameter.
