Title: Fluid rotary joint structure for rotary fluid pressure cylinder device
Inventor: OTA KOJIRO
IPC: B23B31/30
Filed: 1989-04-10
Abstract: PURPOSE:To restrain the exoergic attending with a high speed rotation by externally fitting a cylindrical fluid feeding material in a rotator shaft through a sleeve, and indirectly mounting a ball-and-roller bearing between the sleeve and the shaft, and applying the pre-load with an elastic material. CONSTITUTION:A moment for inclining a shaft 1a is worked on a fluid rotary joint, and the moment is increased as the rotating number rises, and radical displacements of bearings 27, 28 are increased and an annular clearance between a sleeve 8 and the shaft 1a becomes uneven. In the case of indirect mounting, the force F=M/L2 working on the bearings 27, 28 with the moment M is reduced because a distance-between-intersections L2 between a contact line m3 and a rotary center shaft line C4 becomes large. A spring 29A presses an outer wheel of the bearing 28 to right against an inner wheel, and the reaction force presses an outer wheel of the bearing 27 to right against an inner wheel through the sleeve 8 to make the distance-between-intersections L2 large. Consequently, a clearance can be reduced to maintain the leakage oil constant, and length of the sleeve 8 can be reduced to reduce the exoergic and compactize a device.

Title: Device for detecting eyeball position of vehicle driver
IPC: G01B11/00
Filed: 1992-03-17
Abstract: PURPOSE:To increase the efficiency of eyeball detection and shorten the time for processing by using as a reference an eyeball present region defined by means of scanning of an input image of a face, and detecting the eyeball positions of the driver within a set eyeball searching region. CONSTITUTION:An image of the face of a driver D is taken by a CCD camera 302 in synchronization with emission of light from an infrared stroboscope 300, and is stored as information about density and gradation on image memory 308. Whether or not the seated state of the driver is controlled is checked, and when the seated state is not controlled an eyeball present region specifying counter N is reset to 1 and the width and length of the eyeball present region are specified. The coordinates of the specified region are stored 308, and when the counter N is at a number more than 10, an eyeball present position specifying circuit 310 calculates the average position of the eyeball present region and sets an eyeball searching region corresponding to the speed at which the vehicle runs. When the iris is detected 312 within the set region, the eyeball position is regarded as being detected, and the next image taking process is started. When the eyeball is regarded as not having been detected, a detecting process is performed again from photographing of the face image.

Title: Manufacture of catalyst substrate
Inventor: FUKUZUKA TOSHIO
IPC: C25F3/06
Filed: 1980-07-05
Abstract: PURPOSE: To obtain a rough surface with high adhesion by heat-treating a steel plate under suitable conditions before or after working and by carrying out electrolytic etching in a soln. contg. halogen ion.  
     CONSTITUTION: A stainless steel plate is heat-treated at about 500W850°C. As the final working rate applied to the plate is increased, the treating temp. is made lower and the treating time is made longer. The heat-treated plate with Cr carbide deposited on the surface is electrolytically etched in a soln. contg. halogen ion to allow the deposited Cr carbide and its periphery to be leached out preferentially. By this method a uniformly rough surface is obtd. over the whole surface of the steel plate, and the adhesion to a catalyst carrier is enhanced.

Title: Phase controller and phase control processing method
Inventor: TAKADA TOMOHITO
IPC: H04N7/16
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a device/method which can control the phases of such signals that are not added synchronously with each other and also signals that are hard to be detected synchronously with each other in a device that processes with switching the input signals received from plural devices. SOLUTION: When a system is started, a scrambler 7 produces a scrambled test signal 3 from an input changeover switcher 1 which distributes the signals to the external devices 4, 5 and 6. An output changeover switcher 14 switches the output signals received from the devices 4 to 6. A descrambler 16 cancels the scramble as long as the phases of these signals are controlled. A phase control 17 controls the 1st to 3rd phase controllers 11, 12 and 13 to shift the phases from the reference value until the descramble is canceled for the signals which are inputted to the descrambler 16. Then the control 17 outputs a control signal when the phase control is over for the signals inputted from the devices 4 to 6 and actuates the switcher 1 to switch the signal 3 to a main line system input signal 2.

Abstract: PURPOSE:To facilitate the manufacture of a color filter substrate executed by laser beam machining, and to realize a high numerical aperture and a high yield by forming a specific laser protective layer on the substrate in advance. CONSTITUTION:On a translucent substrate 1, a color filter layer 2 of RGB-BL is provided, and on its layer 2, a flattening layer 3 consisting of a resin for flattening the upper face of a filter is provided, and on it flattening layer 3, a protective layer 4 to a laser light is provided, and also, on this protective layer 4, a transparent conductive layer 5 is provided. In this case, as for the layer 4 which becomes the base of the transparent conductive layer 5 to be worked, it is desired to be a substance having higher heat resistance than that of the transparent conductive layer 5. Also, since the machining utilizes light, not only a problem of a temperature, but also an absorption factor of light becomes a problem. That is, in the case where an absorption factor of wavelength of a laser light of the layer 4, which becomes the base is large, the layer 4 of the base is machined by the laser light after the transparent conductive layer is machined. Therefore, the substance whose absorption factor is small, and whose reflection factor is large against wavelength of the laser light.
