Title: Method for trimming resistor
Inventor: ONO SEIYA
IPC: H01C17/24
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for trimming a resistor of which the resistance can be finely adjusted and a high-precision resistor can be obtained. SOLUTION: A resistor 3 is formed on an insulating substrate 1. The resistor 3 is irradiated with a scanning laser beam in the directions of x-axis and y-axis. For adjusting resistance value, when the value is near the target value, a y-axis driver 9 and a y-axis mirror 11 are driven for scanning the laser beam in the direction of y-axis, and change in resistance measured with a measuring instrument 5 is calculated by a controller 7. The maximum value and the minimum value of the rising ratio of the predetermined resistance are compared. When the changing amount is larger than the maximum value, the scanning of the laser beam is performed in the direction so as to reduce the resistance by driving an x-axis driver 8 and an x-axis mirror 10.  When the changing amount is smaller than the minimum value, the scanning of the laser beam is performed in the direction so as to increase the resistance by driving the x-axis driver 8 and the x-axis mirror 10. The change in resistance is reduced so that the value little by little approaches the target value.

IPC: A47K13/10
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To accurately determine an origin by setting a position as the origin where a seat and a seat cover are closed and kept in contact with a toilet bowl, regarding a toilet bowl where the totally close position of the seat and the seat cover is used as the origin and an open/close drive speed is changed, depending on the angles of the seat and the seat cover with the origin. SOLUTION: Switches 31 and 35 are operated when a seat cover 33 and a seat 29 are in a totally open state. Then, a controller 25 controls two-phase stepping motors 15 and 27 for closing both of the seat 29 and the seat cover 33. In this case, the controller 25 reads an output signal from an encoder 26 and stops the operation of the two-phase stepping motors 15 and/or 27, according to a fluctuating signal, upon the contact of the seat 29 and the seat cover 33 with a toilet bowl. At the same time, the controller 25 causes the contact position to be stored in a memory as a totally close position. Then, the controller 25 calculates and finds the current angles of the seat 29 and the seat cover 33 on the basis of the number of signals from the encoder 26, after the start of the motors 15 and 27 at the totally close position.  A drive speed for the open/close control of the seat 29 and the seat cover 33 is thereby changed.

Title: Internal pump of boiling water reactor
Inventor: SUZUKI KOICHI
IPC: G21C15/243
Filed: 1987-10-16
Abstract: PURPOSE:To enable purge water to sufficiently increase temperature by providing spiral channels as a purge water passage on the outer and the inner peripheral faces of a stretch tube. CONSTITUTION:On a stretch tube 12 spiral channels 18 are formed as a purge water passage on the outer peripheral face. A part of purge water which is injected from a purge water inlet 17 to a motor case 8 rises as it is turned along the channel 18, the other part thereof comes in the inner peripheral side of the tube 12 from a lower inner peripheral side outlet 19 and rises in a gap between the tube 12 and a motor shaft 10. In this rising process the temperature of the purge water is gradually increased by heat transfer from the tube 12 of high temperature, the case 8 and the shaft 10. Since the passage of the purge water rising along the channel 18 therein is lengthened to form spiral, specially temperature up is effectively performed, the temperature difference between reactor water and the purge water is lessened and heat fatigue is reduced for a welding part 11. Further, a spiral channel on the inner peripheral face of the tube 12 is provided and so the effect of temperature up is also obtained.

Abstract: PURPOSE:To enable discrimination and detection of a phase missing by judging forward and backward ways of position and speed detection signals to compare and judge the signals with a sample signal with addition and subtraction thereof. CONSTITUTION:By a command of a center controller 2, a servo motor 3 turns a feed shaft 4 in a desired direction to move a tool head 1 to a specified position. Then, a position encoder 5 and a speed encoder 6 output a signal pulse and a position decoder 10 and a speed decoder 8 at the next stage judges whether the movement of the head 1 is forward F or backward A. Then, an output pulse of the decoder 8 is inputted to an addition/subtraction circuit 9 to be counted each in a forward way or backward way and a pulse signal of the position decoder 10 is inputted to an OR circuit 11, which outputs the signal to a resetting circuit 12 to reset a signal pulse being counted with the circuit 9. Here, a comparative judgement circuit 13 compares an integral value of the circuit 9 with a sample integral value to distinguish an output attributed to a phase missing from a signal output being interrupted for a fixed time as caused by a backlash, thereby allowing the device 2 to continue or stop the movement of the head 1.
