Title: Method of controlling automobile suspension device
Inventor: TSUBATA HIDEO
IPC: B60G17/052
Filed: 1987-08-26
Abstract: PURPOSE:To enhance the control accuracy of an automobile suspension unit by obtaining an actual charge and discharge amount from the internal pressure of the suspension device and the vehicle height, and by calculating an error between a control section instructed value and the actual charge and discharge amount, and by compensating the set value of opening and closing time of a control valve, repeatedly at predetermined intervals, so as to obtain a standard charge and discharge amount. CONSTITUTION:When a controller 5 receives detection signals from a suspension internal pressure sensor 4 and a vehicle height sensor 2, the controller 5 computes and measures an actual charge and discharge flow rate. Further, a compensation instructing section 15 delivers a compensation instruction for changing the time characteristic between the flow rate and the valve opening in accordance with the rate between a flow rate instructed by the controller and the actual flow rate, to the controller 5. When the controller 5 receives this compensation instruction, the controller 5 determines a valve opening time in accordance with the valve opening time characteristic which has been changed, and controls a control valve 6. The compensation instruction is issued from the compensation instructing section 15 every predetermined time (few seconds to few minutes). With this arrangement, it is possible to enhance the controllability.

IPC: H01L29/812
Filed: 1984-10-09
Abstract: PURPOSE:To reduce the variability in threshold voltage caused by the lateral diffusion of impurity after injection by a method wherein a semiconductor layer of one conductivity type is formed on one main surface of a semiconductor, and a recess groove is formed in the surface of the semiconductor substrate across the semiconductor thickness. CONSTITUTION:An ion-implanted layer 2 is formed by Si ion implantation to the surface of the GaAs semi-insulation substrate 1. Thereafter, an Si nitride film 3 is deposited by CVD, and a window 4 is opened by photoetching technique and etched into the recess groove 5. At this time, if the thickness of the ion- implanted layer 2 is 1mum, the formation of an etching groove 5 of 1mum or more is needed. Next, an active layer 6 is formed by dissociation growth of GaAs at the side part of the recess groove 5 on heat treatment at 850 deg.C for 40min under As pressure. Thereafter, the Si nitride film 3 is removed, and another Si nitride film 7 is deposited.

Title: Improvement of torque rod-bearing assembly
Inventor: MCLAUGHLIN RONALD J
IPC: F16C11/06
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a vehicular joint assembly having a high load bearing capability and improved performance by providing two basic parts including a dual axis part bar-pin journal and an elastomer bearing socket to be eternally lubricated and sealed throughout the life. SOLUTION: A bearing socket 144 is formed of an elastomer compound such as a urethane or natural rubber compound having the appropriate physical properties. A bar-pin 142 includes a hemispherical ball or a slide surface 170 and a non-metallic low-friction bearing material coating 172. The coating 172 is applied by an economical half-precision injection method. By this method, control for an accurate tolerance and smooth surface finishing is enabled. The coating 172 prevents the relative movement from being mechanically and/or chemically generated between the front surface 170 and the coating 172. Accordingly, the slide motion is limited between the outer front surface of the coating 172 and the inner front surface 174 on the bearing socket 144 and also generated.

Title: Massaging device
Inventor: YODA HIROKI
IPC: A61H7/00
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To perform a desired massage without shifting the contact position of a massager and a site to be massaged by changing massaging force to the site to be massaged by the massager, whose curvature is successively varied by changing the position of an arm with respect to the shaft by rotating the shaft, so as to change the strength of massaging. SOLUTION: Right and left shafts 1 are extended from a massaging part 5 by being pivotally supported around a shaft center X by bearings 6. The arm 2 is folded and extended at the tip part of both of the shafts 1 to hold the massager 3. Both of the shafts 1 are drive-rotated by a rotation means consisting of a motor 7, a transmission shaft 8, respective gears 9a, 9b, etc. The curvature of the surface of the massager 3 is successively varied. The strength of massaging is changed by changing strength of massaging force to the part to be massaged B by the massager 3 by drive-rotating both of the shafts 1 to change the position of the arm with respect to both of the shafts 1. Since the operation locus is not varied at this time, a desired massage can be given without shifting a contact position with the site to be massaged B.

Title: Optical low-pass filter and image pickup device equipped with same
Inventor: NISHIDA YASUAKI
IPC: H04N5/357
Filed: 1990-08-10
Abstract: PURPOSE:To suppress the formation of an image of a diffraction grating on an image pickup surface by arranging two gratings in two directions while they deviate from the array of picture elements of a solid image pickup element, and setting the period of the diffraction grating image less than the horizontal and vertical periods of the picture elements of the solid image pickup element. CONSTITUTION:The optical low-pass filter 4 consists of the diffraction grating which has gratings in two mutually orthogonal directions and the gratings in the two directions are arranged deviating from an image pickup surface. When the effective period is less than the period of one group of color filter arrays, the period of the diffraction grating image is small even if moire fringes are formed, so the light-shade contrast of the moire fringes becomes low, so that the diffraction grating image is inconspicuous. Consequently, the formation of images of the respective gratings of the diffraction grating constituting the optical low-pass filter on the image pickup surface can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To photograph a picture with appropriate exposure by flash photographing regardless of a distance to a subject by changing the length of a photoelectric conversion time according to whether or not the subject can be illuminated with flash light to specified luminance. SOLUTION: An exposure time is set to a specified time or to be longer than the specified time according to whether the subject is illuminated with flash light to be appropriately exposed or the subject is underexposed even though it is illuminated with the flash light. Namely, the exposure time is set to a specified value when the subject is positioned within a distance range where it is appropriately exposed by a maximum emitted light quantity or under and it is set to be longer than the specified time when the subject is positioned at the distance where it is underexposed even though a diaphragm 102 is set at an open position and a flash 18 is made to emit light by the maximum light quantity.  An underexposure decision part 212 decides whether or not it is underexposure by using range finding data from GNo of the flash 18, the open aperture value of the diaphragm 102 and range-finding data from a range-finding module 15.
