Filed: 1992-06-16
Abstract: PURPOSE:To make computation of a floor response spectrum at a high speed possible and in consideration of the uncertainty of a response time history which can occur in practice, by providing a power spectrum density computing means and a floor response spectrum computing means. CONSTITUTION:A frequency analyzer 1 computes a power spectrum density of a building floor, a piping system or the like from a response acceleration time history at a position of installation of the building floor or the like which is obtained by a dynamic analysis of a building or a building-equipment compound system. The result obtained by the analyzer 1 is inputted to a floor response spectrum calculator 2. The calculator 2 calculates a transmission function and the number of transient response series of one particle system while varying a natural period for a specific attenuation constant. Then, it determines the power spectrum density of the absolute response acceleration time history of one particle system for each natural period. Moreover, it determines the maximum value of the acceleration time history corresponding to this density, with a phase made random and on a probability theory basis, while taking in an effect produced by the narrow-band characteristic of a spectrum being peculiar to a low attenuation system. In this way, a floor response spectrum having a probability distribution is computed.

Title: Magnetically driven arc welding method
Inventor: MIHIRA SHIYOUJI
IPC: B23K9/08
Filed: 1980-11-07
Abstract: PURPOSE: To obtain a weld zone of good quality by changing an arc current that generates arc and magnetic coil current that generates a magnetic field during welding and rotating arc of stable length and thereby deepening penetration.  
     CONSTITUTION: In the initial stage of welding, a strong magnetic field is formed in the welded area by letting magnetic coil current flow strongly from a time T 1 . Next, arc current is let flow from a time T 2  and time T 2 -T 3  is sloped up. Then, an arc generated between the electrode and joint is rotated at high speed by mutual action of small arc current and high magnetic field to preheat the welding joint. Arc current is increased during the time T 4 -T 6  in the intermediate stage of welding and magnetic coil current is lowered and rotating force is reduced to deepen penetration and to stick weld metal while preventing scattering. During the time T 6 -T 9  in the later stage of welding magnetic coil current is strengthened again and the arc is rotated at high speed to scatter excessive molten metal. At the same time, arc current is sloped down to obtain stable bead.

Title: Internal combustion engine variable valve timing adjusting device
Inventor: UEDA KENJI
IPC: F01L1/34
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To provide a valve timing adjusting device capable of releasing a locking means before relative torque generates between a housing member and a vane member. SOLUTION: The length of a valve member 45 is about the same as the axial length of a shoe 11b. Because the valve member 45 is abutting on the lateral on the delay angle side of a vane 14c by a spring member 46 force at the most delayed angle position, hydraulic fluid is not supplied to the whole body of a spark advance hydraulic chamber 66. Consequently, hydraulic pressure in a hydraulic chamber 37 rises faster than the whole hydraulic pressure in the spark advance hydraulic chamber 66 of the three chambers. Thus hydraulic pressure in the hydraulic chamber 37 rises and a stopper piston 30 slips out of a taper hole before a vane rotor 14 rotates from the most delayed angle position to the spark advance side, therefore the stopper piston 30 does not have a chance to hinder the relative rotational movement of the vane rotor 14 and a shoe housing 11.
