Title: Shutter and control method for closing body of the same
Inventor: NAKAJIMA KOJI
IPC: E06B9/68
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a shutter capable of being easily assembled and retaining the closed condition of a section to be closed by a closing body while preventing limit of installed locations. SOLUTION: A fire-resistant screen device 3 as a shutter is provided with a noncombustible sheet 8 vertically movable along an opening 1 to be closed. When closing the opening 1 by the sheet 8, the sheet 8 is lowered by its own weight and then, the sheet 8 is raised while retaining the fitting condition of a throating body 10 to the floor and moving downward the throating body 10 relative to a weight 9. When an engaging part is engaged with a engaging means, the sheet 8 is stopped. The whole dead weight of the sheet 8 does not act on the floor and no gap arises between both side edges along the transfer direction of the sheet 8 and a guide rail 4 even when the installation position of the engaging means is not finely adjusted.

Title: Scanning type optical range finder
Inventor: UIRIAMU EICHI TEIRAA
IPC: G01S17/931
Filed: 1994-04-08
Abstract: PURPOSE: To provide a small-sized and compact scan type range meter showing a wide field of view and a high distance resolving power by using plural vibrating mirrors as a scanning element. CONSTITUTION: Two lines of sight are scanned accurately in synchronization with each other by two synchronized vibrating mirrors. These lines of sight are separated from each other at a distance W, thereby generating a parallax angle to the near target. The nearer the target is, the larger the angle δ is. Incoming light from both channels is sent to a lens, and the lens forms an image of a picture element on the lines of sight. For the remote target, the picture element is equal to both lines of sight, and a first detector element of a linear detector array is equally started by light from each channel. For the near target, a difference is produced in starting the detector element, and the difference is in inverse proportion to the distance.  The total dimensions D of the linear detector array are determined by the target having the shortest distance and it has no relation to the scanned field of view.

Abstract: PURPOSE: To automatically detect defects, etc. as count values even if they are irregular in sizes by using a memory having stored matrix coordinates.  
     CONSTITUTION: A memory in which (N)number of defect addresses by the matrix coordinates constituting the defects 1 of defect pattern groups 2, 3 in 1 to n addresses is prepared. The respective 2 coordinates of the defect addresses are respectively compared and whether these are adjoining (including diagonal direction) with a difference by 1 address or not is retrieved. With a reference address as 1 address, it is compared with other addresses and if there are adjoining addresses, a flag bit is attached after that address. When the comparison up to the n address is finished, retrieval is made while jumping the flagged addresses and attaching the flag to the reference address if there is no flag in the reference address and there are flags in the adjoining addresses from the 2 address similarly up to the n address. Upon ending of all the comparisons, the number of the defect addresses by the matrix coordinates having no flags is counted and is made the number of the groups 2, 3 of the defects.

Title: Torsional torque signal abnormality detecting method for electric power steering device
Inventor: OSHITA SAIICHIRO
IPC: B62D5/04
Filed: 1988-03-25
Abstract: PURPOSE:To enable correct decision of abnormality by deciding abnormality of a torsional torque sensor when the handle steering angle speed is more than a fixed value and the status where the steering angle is in the increasing direction continues during a fixed time or more in the status where a torsional torque signal is considered to be zero. CONSTITUTION:An electric power steering device includes a torsional torque sensor for detecting torsional torque of a steering shaft, wherein steering assisting force is decided according to the torsional torque detected by the sensor to control electric power supplied to an electric motor. In this case, when the steering angle of steering handle is more than a fixed value and the status where the steering angle is in the increasing direction continues more than a fixed time or more regardless of the status where a torsional torque signal is considered to be zero, it is decided that the torsional torque signal is abnormal. Thus, abnormal torsional torque signal is distinguished from a normal condition where the handle is not steered and a torsional torque is not generated so as to enable exact detection of abnormality.
