Patent JP-H0960047-A (JP)
Title: Hydraulic drive device
Inventor: YASUDA HAJIME
IPC: E02F9/20
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To lessen an operational burden for an operator to adjust a bucket motion locus in swinging a hydraulic shovel and elevating a boom. SOLUTION: When weight in a bucket increases the value of k×Qbm becomes smaller than the value of Qbo . Thus, a control part 15 performs a process 29, so as to keep Qb equal to k×Qbm . A regulator 3b controls a pump at k×Qbm , smaller than an ordinary target delivery flow Qbo , and at a target delivery flow Qb2 for power control. As a result. the delivery flow Qb of a hydraulic pump 2b changes like a process from (a) to (d) via (b) along iso-power curves. In this case, the hydraulic pump 2a is in a normal control state through positive control and power control. and delivers a target delivery flow Qa1 , corresponding to the positive control, or a target delivery flow Qa2 corresponding to the power control. A boom, however, cannot be elevated much, due to a heavy load.  A delivery flow from the hydraulic pump 2b is, therefore, kept at a corresponding lower level, and the speed of a slewing motor 8b is lowered, thereby maintaining a good balance between a boom elevation amount 1b and the swinging amountsw thereof, regardless of a load.

Inventor: ONO YOSHITAKA
IPC: B05C7/08
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to form a coating layer which is secure in a tight contact state by extrusion molding a coating material in a molten state along the inner periphery of a pipe from a circular die while retreating in the longitudinal direction in the pipe and forming the coating layer by cooling while pressing the material to the inside surface of the pipe by means of a roller. SOLUTION: When the inside surface of the existing buried pipe 21 is subjected to coating, a tube 3 with an extrusion head 5 at the front end is inserted into the pipe 21 from its one opening end and the front end is disposed to face the other opening end. Next, the roller 9 is connected via a spherical surface joint 8 to the front end of the extrusion head 5 and thereafter, an extruder 2 is driven and the coating material is melted in a molten state by this extruder 2 and supplied to the tube 3 and extruded the molten material from the circular die 5a of the extrusion head 5 through the inside hole 4a of the spherical surface joint 4. The extrusion head 5 is retreated in this state and the coating material is continuously extruded to the inside surface of the pipe 21 and is brought into tight contact with the inside surface of the pipe 21.  The coating layer 22 is cooled to solidify by the roller 9 in which the cooling water is circulated by a cooling water hose 10.

Filed: 1993-08-04
Abstract: PURPOSE:To provide a highly accurate and convenient pinhole element by equipping a photo sensor having a pinhole to allow the passage of a light flux and a shading section to block a light flux outside the pinhole. CONSTITUTION:A mirror 2 and a lens 3 for optical axis adjustment are laid on the optical path of a light flux 14 emitted from an illuminant 1, so as to keep the pinhole 9 of a pinhole element 8 aligned with the focal point of the lens 3. Also, the element 8 is placed on a two-dimensional positioning mechanism. A photo detector 15 detects the light flux 14 transmitted through the pinhole 9 of the element 8. When the flux 14 is incident on any of divided elements, the element exposed thereto outputs a signal for the receipt of light. Also, the two-dimensional positioning mechanism is operated according to the magnitude of the signal, for adjusting the amount of luminous energy received with each divided element at uniform and minimum level. As a result, the pinhole 9 is accurately aligned with the position of the focal point.

Title: Flap support mechanism
Inventor: UNE ATSUNOBU
IPC: H01L21/027
Filed: 1984-10-11
Abstract: PURPOSE:To enable ready supply of large flap displacements in an arbitrary direction by performing positioning work in a short time by a method wherein a flap means of changing the first and second members in non contact is provided, and both members are joined together with a plurality of cross finger springs provided with cuts columnar and rectangular to the column axis. CONSTITUTION:Cross finger springs 16-19 joined with brackets 21 and a mask holder fitting frame 13 are provided in a direction of 45 deg. to the X axis and the Y axis and have cuts columnar and rectangular to the column axis. The interaxial interference with the current passed through electromagnets 5 and 7 which supply flap displacement in the Z-axial direction at a point of 27mm off the center is very small with the maximum of about 14%. Besides, the bending rigidity and the rotation rigidity of the cross finger springs 16-19 are very large; therefore, the interaxial interference in the X- and Y-axial directions is very small. Further, the rigidity of the springs 16-19 is small, so a large flap displacement can be supplied to a mask 1. Since the rigidity of the springs 16-19 against flap displacement is fixed regardless of direction, the mask 1 can be readily supplied with flap displacement in an arbitrary direction.

Filed: 1993-08-26
Abstract: PURPOSE:To provide a displacement detector in a noncontact power supply for a mobile body in which the field of a primary coil is sensed and the displacement of a running vehicle with respect to the primary coil is detected. CONSTITUTION:Secondary coils 5, 6 are arranged side by side on the bottom of a running vehicle 1. Currents induced in the secondary coils 5, 6 are fed to power converting sections 7, 8, respectively.

Abstract: PROBLEM TO BE SOLVED: To prevent breaking of a sheet caused by reversion of a rolled stock by adding a current reference value which is converged to zero at a prescribed timewise change rate to current controllers for mill driving motors during stopping a rolling line. SOLUTION: A difference ΔV between an actual speed VFB measured with a speed detector 2 and a speed reference value Vref calculated with a speed reference arithmetic unit 1 is inputted to a speed controlling means 4. A current reference value Iref1 which makes the difference ΔV zero is calculated with the speed controlling means 4, the current reference value Iref1 is added to the current controller through a normally closed switch 7a and reference output switch 5. When a rolling mill is stopped, the current reference value Iref2 with which is made zero at the prescribed timewise change rate from the current reference value Iref1 is outputted with the current reference controlling means 6. The current reference value Iref2 is added to the current controller through the normally opened switch 7c and switch 5.  In this way, since the current reference value Iref2 is not suddenly varried, the rolled stock is not reversed at the time of stopping a rolling line.
