Abstract: PURPOSE: To apply an inverse-polarity voltage to thyristors and improve efficiency to a higher frequency region by turning on one of two pairs of electric valves provided on positive and negative dc bus lines at the time of commutation of the thyristors which supply ac to a load.  
     CONSTITUTION: Electric valves 2 and 3 are connected to a dc power supply so that they are turned off when a thyristor bridge 4 is commutated, and electric valves 11 and 12 are provided to discharge a capacitor 9. When thyristors S 1 ∼S 3  are on and S 2  and S 4  are going to be turned on after commutation, a current level sensor 16 operates, the electric valve 2 is turned off, and the electric valve 3 is turned on by a logic circuit; and when electric valves 11 and 12 are turned on, the capacitor 9 is discharged, an inverse voltage is applied to S 1 , S 3 , and S 5 , and blocking ability is quickly restored. When S 2  and S 4  are on and S 3  and S 5  are going to be turned on after commutation, the same function is performed. In this constitution the period for restoring the thyristors are greatly shortened and efficiency is improved even in a higher frequency region.

Title: Joint of rotation difference sensitive type
Inventor: YOSHIBA HIROSHI
IPC: B60K23/04
Filed: 1990-05-21
Abstract: PURPOSE:To maintain torque transmission control performance corresponding to a rotation steed difference at the time of normal running operation and restrain the performance at the time when torque transmission is not unnecessary so as to prevent swinging of a vehicle at its rear part by arranging in a juxtapose manner a discharge oil passage provided with an orifis and a bypass discharge oil passage provided with an oil passage opening/closing control valve. CONSTITUTION:No pressure oil is supplied from a control pressure oil passage 120 upon normal running while a spool valve 110 closes a bypass discharge oil passage 100 with pressure of an accumulator chamber 70. When relative rotation occurs in both output shafts 15, 16, a driving piston 40 sliding on a cam 21 reciprocates and due to resistance at an orifis 90 of a discharge oil passage 60 pressure of cylinder chamber 50 increases. Then hydraulic pressure acts on the driving piston 40 to compress the cam face 21 thereby generating differential control torque. In the case where differential torque is not required, pressure oil is supplied from the control pressure oil passage 120 and the bypass discharge oil passage 100 is opened to flow work oil in the bypass passage 100, thereby restraining the differential control torque to a small level.

Then scattered light which is Doppler-shifted is converted 8, the quantity of light based pon the light and dark parts of interference fringes are detected,a nd an arithmetic means 14 finds the moving speed.

Filed: 1995-05-29
Abstract: PURPOSE: To reduce the measuring error of a coordinates measuring device (CMM) and enhance its measuring accuracy by correcting the measurements with a corrective value representing the flexural characteristics of CMM when the coordinates of the work to be processed are measured thereafter. CONSTITUTION: The elastic flexural characteristics of a coordinates measuring device (CMM) are determined on the basis of the positions of measuring carriages 2, 4 for various affecting amounts, for example, the measuring force, acceleration and measuring capacity of device, and the corrective value is calculated from the obtained flexural characteristics. The measuring error resulting from a machine bending can be corrected with this corrective value. The corrective value depends upon the positions of the carriages 2, 4, i.e., the position of scanning head, and therefore, determined for various positions and stored. This method according to the present invention can be combined with a guide error correcting method developed on the basis of a fixed model and with the dynamic correction method for machine deviations resulting from vibrations of machine member(s).  By these three correcting methods, the unstability in measurement can be minimized.
