Title: Integrated circuit device having multilayer interconnection
Inventor: YAMANAKA TAKASHI
IPC: H01L21/314
Filed: 1983-05-06
Abstract: PURPOSE:To reduce the influence by the abnormal growth of an Si nitride film by using the multilayer film of a thin Si dioxide film and a thick Si nitride film as the insulation film between the first and second metallic wiring layers. CONSTITUTION:The first metallic wiring layer 15 connecting an active element to a passive element on a substrate is formed. The Si dioxide film 16 is adhered on the wiring layer 15. The Si nitride film 17 is adhered on the Si film 16. The second metallic wiring layer 18 is formed on the Si film 17. Then, the influence by the abnormal growth of the Si film 17 reduces. Since the Si film 16 exists as the barrier, the amount of accumulation of charges from the wiring 15 into the Si film 17 also decreases extremely.

Title: Ball joint
Inventor: SHIRAI TAKEKI
IPC: F16C11/06
Filed: 1995-04-04
Abstract: PURPOSE: To prevent the occurrence of a joggle in a non-load state by a method wherein an opening part communicated with the spherical body support part of a holder is formed and a resilient member is arranged at an opening part. CONSTITUTION: A resilient cap 8 mounted on an opening part for insulating the vibration of a spherical body support part 2 is brought into contact with a spherical body part 5 by means of a press force high enough to allow slight resilient deformation of soft synthetic resin. In the press direction thereof, a gap between the spherical body part 5 and the spherical body support part 2 is eliminated and the spherical body part 5 is nipped between the resilient cap 8 and the spherical body support part 2. Namely, since the pressure force of the resilient cap 8 is exerted in the direction of the opening part 14 for coupling of the spherical body support part 2, a reaction force against the press force of the resilient cap 8 is exerted on the spherical body part 5 along the edge part of the opening part 14 for coupling.  Thus, resistance is exerted on rotation, based on the spherical body support part 2, of the spherical body part 5 and in such a state that no load is transmitted between a rod 4 with a ball and a holder 1, even when vibration is applied on a ball joint, joggle is prevented from occurring.

IPC: G01B9/02
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To make interference fringes countable by measuring DC components of an interference signal using an integrator for correction so as to convert the interference signal into a signal only with AC components. SOLUTION: In a signal processing circuit 40, a signal obtained by a photoelectric conversion element 8 is converted into an electric signal by a current- voltage converter 41, then subjected to smoothing of high frequency components in a low-pass filter 42 and digital-converted by an analog-to-digital converter 43. The average value of the maximum value and minimum value of the interference signal during the specified displacement of a reflecting means 5 is then obtained by a level detecting circuit 44. After latching this value by a latching circuit 45, the interference signal is made into an analog signal by a digital-to- analog converter 46, and the difference from the output signal voltage of the current-voltage converter 41, containing DC components is obtained by a differential amplifier 47 so as to obtain the interference signal only with AC components.  Also in a signal processing circuit 50, a signal obtained by a photoelectric conversion element 7 is subjected to the same processing to obtain an interference signal only with AC components.

Filed: 1988-03-31
Abstract: PURPOSE:To always enable the stable measurement even when the state of an objective surface and its inclination against the direction of incident light are changed by disposing position sensors in conforming their light receiving directions to plural directions at a fixed angle. CONSTITUTION:A circular cone is assumed as its center line as the incident light 10, vertex as an incident point P and vertical angle as 2theta, and the position sensors 1-4 are provided at approximately quarters dividing a circumference formed by cutting this cone with a plane which is orthogonal to the center line, whereas the light receiving directions of these sensors 1-4 are passable through a reflecting point P. And, reflecting rays 11-14 are from the reflecting point P to the position sensors 1-4. Then, the incident light 10 is incident upon the surface of the measuring object 8 in a slantwise direction to this surface and diffusionally reflected at the point P. Now, supposing that the surface of the object 8 is a perfect diffuse surface, a reflected light distribution curve is indicated as a circle verging on the surface of the object 8 at the point P. Thus a reflected light having enough luminous intensity to output a stable detecting signal can be incident upon at least one of these sensors 1-4.

Title: Revolution speed controlling device for motor
Inventor: FURUHATA TAKASHI
IPC: H02P29/00
Filed: 1979-06-27
Abstract: PURPOSE:To economize the power consumption and to reduce the introducing time to a control system by obtaining a signal with a modulation means having the same period as a revolution speed signal and a duty ratio which is changed by an error signal with a reference signal and also by controlling a driving circuit with the said signal. CONSTITUTION:By corresponding detectors 8 and 12 to a rotating disc 7 connected to a motor 6, pulse signals G and B having a frequency corresponding to the respective revolution speed is obtained. Then an error voltage E0 is obtained by comparing a signal G with a reference signal H using a phase comparator 2 and it is input to a pulse width modulator 4 together with the signal B. A pulse signal P having a pulse width which is inversely proportional to the intensity of voltage of the voltage E0 is obtained and a driving circuit 5 is controlled by a signal P. As a result, when the speed is low, for instance, the period of the signal P is prolonged and the pulse width is enlarged, thereby enabling to reduce the introducing time to the servo system and improve the starting characteristic as well.

Title: Roll bearing device for rolling mill
Inventor: KANEKO KAZUO
IPC: F16C13/00
Filed: 1985-04-17
Abstract: PURPOSE:To grind safely and easily a roll with bearing boxes with high accuracy by fitting and fixing closely the inner race of a roll bearing device having multi-row cylindrical roller bearings to the neck part of the roll and the outer race to the bore of the bearing box respectively in the radial direction. CONSTITUTION:The inner race 42 of the bearing used in the roll bearing device of a rolling mill having the multi-row cylindrical roller bearings 4 is fitted with a tight fit to the neck part 11 of the roll 1 and the outer face 44 is also fitted with a tight fit to the bore 31 of the bearing box 3. The bearing is assembled to support rotationally the neck part 11 of the roll 1. The clearances in the radial direction in both fitted parts are thereby made zero. The body part of the roll 1 in such assembled state is corrected by grinding. The weight of the roll itself is large in the correction grinding stage of the roll 1 and therefore the whirling of the roll itself according to the rotation of the roll during grinding is substantially obviated. The cylindricity and eccentricity of the body part are therefore kept at about <=10mu in most cases and the accuracy of the body part is maintained within a practicable range.
