Inventor: KIMURA ATSUSHI
IPC: F15B9/06
Filed: 1993-12-28
Abstract: PURPOSE:To improve maintainability and operability by making it possible to change the direction of the feedback shaft of a positioner. CONSTITUTION:A holder main body 441 is attached to a feedback shaft holder attaching surface 42 so that the axial direction of a bearing 442 is 45 deg. to the feedback shaft holder main body 441 and 90 deg. to a valve positioner attaching surface 43. In relation to such a using method, the holder main body 441 is attached to the holder attaching surface 42 so that the axial direction of the bearing 442 is 45 deg. to the holder main body 441 and in parallel with the positioner attaching surface 43. Thus, since the direction of a feedback shaft 45 can be made variable by 90 deg. to the valve positioner main body, the valve positioner can be attached in an optimum direction for adjusting the valve positioner and for maintenance work such as cleaning, inspecting and the like.

Title: Washing contraction prevention technique for neck of shirts or the like and sewing product by sewing machine of the same
IPC: A41B3/00
Filed: 1989-12-22
Abstract: PURPOSE:To prevent contraction after washing without relaxing the tension of the sewing thread of a sewing machine by positioning a water soluble film at a position where the seam of the sewing machine passes that is the longitudinal direction of a sewing product and dissolving away the soluble film when washing the sewing product. CONSTITUTION:The soluble film 7 is positioned at a seam line at the stage of manufacturing process. It is most recommendable to insert the film inside arrow head part where the most of the sewing seam lines exist. When the washing processing of the neck in which the soluble film is positioned inside the sewing machine seam line is performed, the soluble film is dissolved and flows out in washing liquid. Then, space equivalent to the thickness of the soluble film is generated between the needle thread and the bobbin thread of the seam, and the space is very useful to immediately relax the tense state of machine sewing thread, then, the machine sewing thread from which the tense state is removed can be relaxed. In other words, the contractive force of the machine sewing thread at the seam part of the sewing machine is decreased, which generates the relaxed state of the seam.

Title: Exhaust gas recirculation system
Inventor: KUMAGAI SHIRO
IPC: F02M25/07
Filed: 1987-12-29
Abstract: PURPOSE:To perform an exhaust gas recirculation at optimum quantity all the time irrespective of a manufacturing error in a recirculating quantity control valve and a secular change in the whole system by performing the learning compensation of driving quantity in the recirculating quantity control valve on the basis of the detected result of a gas density detector. CONSTITUTION:A part of exhaust gas is led into an EGR gas extracting pipe 22, while its quantity is controlled by an EGR valve 3 and then led into an intake pipe 9. Working negative pressure in the EGR valve 3 is increased or decreased by on-off operation of a solenoid valve 23. An electronic control unit 4 alters a duty ratio of this solenoid valve 23 so as to become an EGR rate conformed to a driving state of an engine E and controls a valve opening value of the EGR valve 3. When feedback control takes place, the duty ratio of the solenoid valve 23 is compensated on the basis of the operated result and the output value of an oxygen sensor 14, thereby driving the solenoid valve 23. Afterward, whether the right and wrong of learning is judged, and when this learning is carried out, it returns to a start point of a control flow after correcting the setting value itself.

Title: Semiconductor integrated circuit device
Inventor: SANO YOSHIAKI
IPC: H01L21/316
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent insulation breakdown by applying a smaller voltage than a voltage being applied to a semiconductor layer to a conductive-type diffusion region with the opposite conduction type to a semiconductor being provided in a region over the horizontal semiconductor layer via a corner part from a LOCOS end. SOLUTION: An inverse-conductive-type diffusion region 58 opposite to a semiconductor layer 50 is formed from the lower end of a LOCOS oxide film 51 to the horizontal semiconductor layer 50 via a corner part 56. On the diffusion layer 58, an electrode 59 being extended to the upper part of the LOCOS oxide film 51 is formed via a recessed part 54. A first voltage is applied to the electrode 59, and a second voltage is applied to the semiconductor layer 50. A voltage that is lower than the second one is applied to the diffusion region 58, and the voltage of the semiconductor 50 is not directly applied to the corner part 56. Even if a thin insulation film part exists between the electrode 59 and the diffusion region 58, the voltage between the electrode 59 and the diffusion region 58 becomes lower than the second one, thus preventing the insulation breakdown of the corner part.

Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To reduce cogging torque, even if the magnetic center of permanent magnets constituting the poles of the permanent magnets for field system does not coincide with the center in the direction of the width. SOLUTION: A rotor 12 is formed by placing six-pole divided permanent magnets 16a-16f on the circumference of a yoke portion. A magnetic center M of the divided permanent magnets 16a, 16s, 16e constituting the north poles of the six-pole divided permanent magnets 16a-16f is shifted form the center G in the direction of the width in a direction of rotation by a specified distance of 'X'. The magnetic center M of the divided permanent magnets 16b, 16d, 16f constituting the south poles is shifted from the center G in the direction of the width in the direction opposite to the direction of rotation shown by the arrow A by the specified distance of 'X'. For this reason, the cogging torque of the north poles and that of the adjacent south poles cancel out each outer, thereby the cogging torque of the entire motor is reduced.
