Title: Measuring apparatus and method for scanning optical system
Inventor: SHIMIZU KENICHI
IPC: G01J1/04
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To shorten a measuring time by measuring the output of each optical element of a photosensor having an array of optical elements in a sub-scanning direction, and reducing the number of optical elements on the basis of information on subsidiary-scanning-direction scanning positions of light spots computed from the measured outputs. SOLUTION: The laser beam of a semiconductor laser 2 condensed by a polygonal mirror 4 is reflected by a mirror and passes an fθlens 5, performs scanning in a main-scanning (y-axis) direction, and irradiates the CCD photoelectric receiving part 8 of a CCD camera 7 arranged on an orbit of light spots on a plane to be scanned. The CCD photo-detector part 8 has a photo-detector element composed of an array of optical elements of 5,000 pixels in the sub-scanning (z-axis) direction, and a picture image input board 10 measures its received signal level, especially the output distribution of each optical element. A personal computer 11 computes the center of the area of an output cross section measured, and processes it as sub-scanning-direction scanning position information.  In this case measurement is performed by causing a laser beam having an orbit of 1 to perform scanning a plurality of times at a plurality of points, but data treatment amount decreases, since the personal computer 11 decreases the number of optical elements to be used in the second measurement and thereafter.

IPC: G06F17/50
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To solve clock skew violation by adjusting the wiring length of a clock path, without changing the logic configuration nor increasing the area, so that the propagation delay time is adjusted. SOLUTION: A clock skew value, which is required from a clock skew value input means 0101, is inputted, and the propagation delay time for clock path is calculated with a propagation delay time calculating means 0102. Based on the propagation delay time, a clock path violating with respect to a clock skew value requirement is detected with a clock path propagation delay time violation detecting means 0103, and the detected clock path as well as the register coordinates connected to it are detected with a coordinate detecting means 0104. Based on the coordinate, a clock path and each register coordinate with which a clock skew is accommodated within a required range are calculated with a clock skew optimization coordinate calculating means 0105, and arrangement/wiring is performed by an arrangement/wiring means 0105, based on that coordinate.

Title: Method for diagnosing partial discharge of gas insulating apparatus
Inventor: IWAASA SHUZO
IPC: G01R31/12
Filed: 1988-11-30
Abstract: PURPOSE:To prevent accident in insulation by a method wherein partial discharge of a gas insulating apparatus is diagnosed by measuring signal from a partial discharge detector with a partial discharge measuring device, and a position of a metal line which has mixed into the apparatus is identified from frequency spectrum, generation phase and discharged amount of partial discharge. CONSTITUTION:Signal detected by a partial discharge detector 1 housed in a gas insulating apparatus 10 is acquired into a spectrum analyzer 2 as a partial discharge measuring device. At this time, the spectrum analyzer 2 is swept with such a trigger that loaded voltage loaded on a high voltage part of the gas insulating apparatus 10 becomes a positive value with zero volt crossed. The signal is acquired also by varying sweep time. A pattern of frequency spectrum acquired into the spectrum analyzer 2 is judged and processed by a computer 3 so that a position of a mixed metal line is displayed.

Title: Power steering device
Inventor: IIZUKA SUSUMU
IPC: B62D5/07
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To absorb and relieve a fluctuation in internal pressure of low pressure piping caused by sudden opening/closing of a control valve by connecting the tip of piping branched off from the vicinity of the upstream end of the low pressure piping reaching an oil reservoir from a power steering unit to the bottom part of a surge tank. SOLUTION: The tip of branch piping 8 branched off from the vicinity of the upstream end of low pressure piping 5 reaching an oil reservoir from a power steering unit 2 is connected to the bottom part of a surge tank 6. When a control valve of the power steering unit 2 is suddenly closed according to sudden steering, a flow rate of an operating fluid returned to the oil reservoir by passing through the low pressure piping 5 suddenly reduces. At this time, internal pressure of the low pressure piping 5 instantly reduces and is going to become negative pressure. In that case, the operating fluid accumulated/held in the surge tank 6 is returned to the low pressure piping 5 through the branch piping 8 to avoid a sudden reduction in the internal pressure of the low pressure piping 5 to thereby prevent generation of an abnormal sound from the low pressure piping 5.

IPC: F04D25/10
Filed: 1987-11-27
Abstract: PURPOSE:To permit the generation of concentrated airflow and diffused airflow by a method wherein a connecting rod is moved left- and right-ward two sets of eccentric cams to direct the left-and-right groups of airflow deflection plates simultaneously toward center or outwardly, in the airflow deflector of an air- conditioner. CONSTITUTION:When a motor 9 is energized a two-stage cam 11 is rotated and an eccentric cam 12 slides on a sliding wall 14, whereby a connecting rod 7 repeats reciprocating motion having the stroke of two times a distance L; therefore, the right-half group of airflow direction changing plates 1 repeats left-and-right reciprocating motion about rotary axis 2. At the same time, the eccentric cam 13 slides on the sliding wall 15 and the connecting rod 8 repeats reciprocating motions having a stroke of two times of the distance L; therefore, the left-half group of the airflow direction changing plates 1 repeats reciprocating motions opposite to the same of the right-half groups about the rotary axis 2. Accordingly, the airflow deflection plates 1 can generate concentrated airflow, in which the left-and-right groups of the plates 1 are faced to the central direction, and diffused airflow, diffusing airflow toward left and right, alternately.

Filed: 1986-12-19
Abstract: PURPOSE:To contrive to enhance the uniformity of a film thickness, by changing a scanning speed supplying a coating solution to the range from the center of a member to be coated to the outer peripheral edge thereof to a specific state to perform coating. CONSTITUTION:A disc shaped glass base plate 4a as a member 4 to be coated is placed on a turntable 25. Next, a motor 27 is started to rotate the glass base plate 4a at a low speed and, thereafter, a control apparatus 37 is operated to open a solenoid valve 44 and, succeedingly, a pulse motor 46 is started to allow scanning to start.
