Title: Slip saturation value control system for inverter device
Inventor: HAYASHIDA TAKAHIRO
IPC: H02M7/48
Filed: 1982-10-12
Abstract: PURPOSE:To prevent an overcurrent from being stopped by varying the saturated value of a slip individually from the rotating speeds of induction motors. CONSTITUTION:A slip is obtained from the deviation between Wref read out from an external input interface and W read out from a speed detector by a slip calculation program 21, compared with slip saturation value pattern for each speed stored in an ROM, suppressed within the limit value as a Ws command, and the sum of W and Ws is used as a rotating speed command W0 of a motor. Since the pattern of a slip saturated value 22 varies depending upon the rated value and the capacity of an induction motor, the optimum value is selected from the characteristics of the motor. The variation of the saturated value of Ws can be performed by using a software processing by a digital control system using a microcomputer which is difficult in a hardware.

Title: Manufacture of hybrid circuit board
Inventor: TAKAYAMA AKIRA
IPC: H01L21/60
Filed: 1983-09-29
Abstract: PURPOSE:To obtain the high property of wire connection by a method wherein a capillary constituting the device is put in connection while being made eccentric in the region within an acute angle the direction of ultrasonic oscillation and the direction of wires reverse to the direction of tension form on pads, when the wires are electrically connected to the pads on a circuit board by means of an ultrasonic wire bonding device. CONSTITUTION:An IC chip 2 and many bonding pads 1a'-1a'' surrounding it are provided on the circuit board 1, and electrode wirings provided to the chip 2 are connected to these pads 1a'-1a'' respectively by means of bonding wires. At this time, since the pads 1a' and 1a'' become parallel or vertical in the direction 4 of bonding wires and that 3 of capillary oscillation, the slip of an alloy layer does not generate during bonding. Slip generates in the pads except those; therefore the pad width is more increased, as the angle between the directions 4 and 3 becomes larger toward the direction of 40 deg., and thus the contact point 5 of the capillary is made eccentric in a pad.

Filed: 1993-07-20
Abstract: PURPOSE:To improve the responsiveness of gas pressure control and improve the stability by re-setting the integration value at the same time that the gas pressure of a gas tank reaches the gas pressure command value. CONSTITUTION:A pressure comparing means 12 compares a command signal PO from a pressure command means 11 with a detecting signal PS from a pressure sensor 2 which detects gas pressure in a discharge tube 5 and outputs a differential signal D corresponding to the difference to an integrating means 14, proportionally calculating means 15 and an integration control means 13. The integration control means 13 outputs a prescribed signal SO (integration value re-setting signal) to the integrating means 14 based on the differential signal when the detecting gas pressure PS in the discharge tube 5 reaches the gas pressure command value PO. The integration value of the integrating means 14 is re-set by the prescribed signal SO. Thus, only the steady condition is to be controlled after the re-set, regardless of the conditions of the previous speed deviation.
