Patent JP-H0997876-A (JP)
Title: Semiconductor device and its manufacture
Inventor: HONNA MASARU
IPC: H01L27/04
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To reduce the error of the total resistance value of polycrystalline silicon resistors composed of polycrystalline silicon films and diffusion resistors composed of diffusion layers connected in series resulting from the error of the forming accuracy of the resistors by forming the diffusion resistors by introducing an impurity into a substrate by using the polycrystalline silicon resistors formed on an insulating film as a mask. SOLUTION: Diffusion resistors 41a are formed by implanting impurity ions into a substrate by using polycrystalline silicon resistors 31a as a mask. When the widths W1 of the resistors 31a become wider than a desired value, the widths W2 of the diffusion resistors 41a formed by using the resistors 31a as a mask become narrower unless the absolute forming area of the resistor elements 41a and 31a changes. Even when the widths W1 become narrower than the desired value and a error occurs in the forming accuracy of the resistors 31a and 41a, the sum of the widths W1 and W2 always become constant. Consequently, even when the cross-sectional areas of the resistors 31a decrease or increase due to the forming error, the cross-sectional areas of the resistors 41a which are used in paired states with the resistors 31a increase or decrease.  Therefore, the total resistance value of the resistors 31a and 41a connected in series offsets the forming error and approaches a desired value.

IPC: B63H25/00
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To provide an azimuth pusher contorl method of and device that use two azimuth pushers so effectively as to reduce their power consumption and noise. SOLUTION: Two azimuth pushers 2 and 3 arranged on a line C2 perpendicular to a hull centerline C1 in the stern-side bottom region of a marine research ship 1 are driven by a DPS or other controller 4. The controller 4 uses mode signals B effecting a longitudinally fixing mode whereby the turn on the line C2 is limited in the same direction other than the normal 360-degree turning mode, so that it can control turning motors 2b and 3b of the azimuth pushers 2 and 3 in the longitudinally fixing mode to provide lateral thrust in holding the ship position when external forces such as winds, waves and tides are relatively moderate.

Abstract: PURPOSE:To grind at high precision a plurality of shafts of control valves of a power steering device. CONSTITUTION:Rough grinding is executed by a grinding wheel 31. The outer diameter part is finish-ground by a grinding wheel 32. The coordinate value indicating the position of a grinder table 14 of the grinding wheel 32 is compared with the finished diameter of the outer diameter part detected by a sizing device 49, and the difference is corrected, eliminating the error due to the thermal displacement of the grinder table 14. Successively, the chamber of a groove 2 of a work 1 is executed by the grinding wheel 32. This constitution eliminates the re-setting of the work and a plurality of works can be ground wihout generating defective alignment. The grinding by correcting the thermal displacement allows the grinding at high precision. The chamfer of the groove part where the in-process measurement is impossible can be correctly executed.

When the driving magnet 1 is rotated, then the waveform of counter-electromotive force generated on the confronting coil is formed in the shape of overlapping harmonic multiplied by minus 5 on a fundamental sine wave, as shown in figure. The amplitudes B1, B5 of the fundamental sine wave and the fifth harmonic are set to be -0.14B1<B5<0. By this method, torque ripple is reduced, and wow flutter can be reduced.

Title: Exhaust gas reflux quantity control device
Inventor: KURITA NORIAKI
IPC: F02D45/00
Filed: 1991-10-03
Abstract: PURPOSE:To provide an exhaust gas reflux quantity control device which has a simple structure and accurately controls the quantity of exhaust gas reflux. CONSTITUTION:The inlet pipe pressure PmNMSS and the number of revolutions of an engine NeNMS are read (905, 907) while EGR is controlled to stop EGR (909). The inlet pipe pressure PmNMSE is read when EGR is stopped (915) to calculate the variation of the inlet pipe pressure DELTAPmNMS (917). Since the variation DELTAPmNMS is approximately proportional to the actual quantity of exhaust gas reflex, the actual quantity can be controlled to the target value by correcting the opening of an EGR valve so that the variation becomes DELTAPmO (919 to 927).
