Title: Two-stage servovalve
Inventor: ICHIYANAGI TAKESHI
IPC: F15B13/043
Filed: 1980-12-05
Abstract: PURPOSE: To improve the frequency response of a pilot valve for a direct-acting servovalve and heighten its stability in quick action, by setting the diameter of the spool of the pilot valve, the dias of the spool of a main valve and the pressure reception area of the main valve at appropriate values, respectively.  
     CONSTITUTION: The parameters most important to quickly and stably drive the spool 14 of a main valve 2 are the pressure reception area S of the main valve, and the diameters (d), D of the spools of a pilot valve 1 and the main valve. These parameters can be changed into a dimensionless parameter α=dD/S. To enable the quick response of the main valve 2, a dimensionless response number equal to the quotient fM/fP of the division of the response of the main valve 2 by that of the pilot valve 1 needs to be 0.3 or more. The value of the dimensionless parameter α is determined so as to satisfy said condition of the dimensionless response number. To ensure the stability of the quick response of the main valve 2, the value of the dimensionless parameter α needs to be 0.7 or less.

Title: Inside-out type battery
Inventor: KURODA AKIRA
IPC: H01M2/18
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To prevent the distance between a positive electrode and a negative electrode from becoming long, increase the mutually opposite surface areas of the cathode and the anode, and improve the reaction efficiency of the positive and the negative electrodes by providing a separator with a polymer part, which can slide by volume increase of the positive electrode in the outer circumferential direction, in the side face. SOLUTION: Since a polymer part 6 of a separator 7 slides due to volume increase of a positive electrode 1 in the outer circumferential direction and the side face of the separator 7 is spread, the volume increase of a positive electrode 1 in the outer circumferential direction is not inhibited by the separator 7. Consequently, even if the negative electrode on the opposite to the positive electrode is lessened due to discharge of the battery, the positive electrode whose volume is increased by the discharge of the battery increases the volume in the negative electrode side positioned in the outer circumferential side, so that the distance between the positive and negative electrode can be prevented from becoming long. Moreover, since the pressurizing force applied to the separator 7 is lessened, damaging the separator can be prevented.

Title: Method for detecting and compensating state of different contact force with multiple-coordinate contact system
Inventor: RUDORUFU SHIYUTETSUTONAA
IPC: G01B21/04
Filed: 1994-07-22
Abstract: PURPOSE: To automatically compensate a contact error in a contact system by putting parameters for the contact system and a calibration gauge into a control device, getting in contact with a calibration surface of the calibration gauge by the contact system, performing contact motion in the direction determined by two coordinate directions, and determining a contact force state and a correction coefficient based on an inclination distance of the contact system. CONSTITUTION: In starting calibration, radius of a contact ball 12, depth of a hole in a calibration gauge 3, etc., are inputted as parameters of a multi-coordinates contact system 6 and the gauge 3. As a contact pin of the contact system 6 is positioned to a flat bottom of the gauge 3, calibration is started. The pin gets in contact with a ring surface of the gauge 3 in X- and Y-directions, and the ball 12 is inserted to determine a center of the gauge 3. It gets in contact with the ring surface from the center, and it is returned to the center again to collide with the gauge 3 perpendicularly to a conical surface. This contact is performed for both the XZ- and XY-directions. Moving motion is superposed on contact motion to reduce friction, and contact force is determined based on distance of inclination of the contact pin.  A correction value determined based on it is introduced into a controller, thereby an error of the contact system 6 can be automatically compensated.

IPC: B23P19/00
Filed: 1994-07-22
Abstract: PURPOSE:To detect the insertion error of all leads by providing a detecting machine for detecting the leads of a part. CONSTITUTION:When a part 1 is inserted to the hole of a base plate 3, the lead 2 of the part 1 is lowered to the lower surface of the base plate 3. A detecting plate 4 is laid in a seesaw form supported in one point, and when the top end of the detecting plate 4 is pressed down by the lead 2 of the part 1, the other top end of the detecting plate 4 is reversely raised. The top end opposite to the end surface making contact with the lead 2 of the detecting plate 4 is monitored by a detecting machine 5. While the detector 5 judges the presence of the detecting plate 4 in the waiting state having no insertion of the lead 2, the detector 5 judges the absence of the detecting plate 4, when the detecting plate 4 is raised by the insertion of the lead 2, because the detecting plate 4 is out of the monitoring range of the detecting machine 5.

Abstract: PROBLEM TO BE SOLVED: To increase the strength of a permanent magnet with respect to centrifugal force by tightly fitting the cylindrical permanent magnet onto a rotor shaft, and press-fitting a cylindrical fiber-reinforced member having a specified fitting allowance onto the permanent magnet. SOLUTION: A permanent magnet 15 is tightly fit onto a rotor shaft 1, and a fiber-reinforced member 16, having a specified fitting allowance, is press-fit onto the permanent magnet 15. Thus a pre-stress is exerted in the direction in which the diameter of the permanent magnet 15 is reduced by the fiber- reinforced member 16, to enhance the adhesion of the permanent magnet 15 to the rotor shaft 1. In addition, an adhesive 17 is placed between the outside surface of the rotor shaft 1 and the inside surface of the permanent magnet 15, to integrate the permanent magnet 15 with the rotor shaft 1 for further enhancement of the adhesion between them. This increases the strength of the permanent magnet 15 with respect to the centrifugal force for the prevention of damage to the permanent magnet 15, and enables high-speed operation of the rotor shaft 1.
