Title: Fog status detection device for vehicle
Inventor: YAMADA KATSUNORI
IPC: B60R21/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To detect an obstruction at the time of traveling in fog at high sensitivity by extracting a high intensity region and an optical curtain region of a tail lamp, etc., from an image of a color image pick-up device to pick up an image of an outer part of a vehicle and computing fog influencing quantity from a proportion of a density value of each of the regions. SOLUTION: A forward traveling image output from a color camera 1 is memorized with an RGB image by converting an RGB color specification system image data of a tail lamp, etc., to an XYZ color specification system image data by an image information forming device 2. Simultaneously, a lightness image is also formed and memorized. The image data is output to a high intensity region extraction device 3 and an optical curtain region extraction device 4. The high intensity region extraction device 3 extracts a lightness region of higher than a designated color setting threshold value from both of the image data, computes a central coordinate position and outs it to the optical curtain region extraction device 4 and outputs an extracted image to an influence judgment device 5.  The optical curtain region extraction device 4 extracts an optical curtain region, computes average density of the region, takes a ratio of brightness of a high intensity region and a medium intensity region and makes it a degree of influence of fog on the influence judgment device 5.

Title: Automatic device for checking mounted printed circuit board
Inventor: MURAOKA KENJU
IPC: H05K13/08
Filed: 1994-03-31
Abstract: PURPOSE:To automatically check a positional error and lift of a lead wire by finding the volumetric center of gravity of a printed circuit board having pads on which electronic parts are mounted and the area center of gravity at the lead center by the light-section method. CONSTITUTION:A laser beam from a laser light source 1 is directed to an object to be measured including a printed circuit board having pads on which electronic parts are mounted by lead wires. Reflected light from the object is received by a camera 2, and is analog-to-digital converted and image-processed by an image processing unit 3. Thus, luminance information is found. An arithmetic operation unit 4 calculates the output of the image processing unit 3, and a control unit 5 controls the on/off of the laser light source 1 and the scanning of the laser beam. The object is three-dimensionally scanned to find the volumetric center of gravity thereof. The object is also two-dimensionally scanned to find the area center of gravity at the lead center. If the volumetric center of gravity and the area center of gravity fall within a predetermined threshold range, the lead is judged to be normal. Thus, positional error and lift of the lead wires and the soldering state are judged automatically and accurately.

Filed: 1990-03-30
Abstract: PURPOSE:To see that a specified illuminator automatically lights up at low illuminance when a person enters a room and that unnecessary automatic lightening can be prevented by equipping it with a human body detecting means, which sends out a human body detecting signal to a controller, and an illuminance detecting means, which sends out a low illuminance detecting signal to said controller when the illuminance is below the set illuminance.

And a driving circuit 14 sends out an opening/closing signal Q2 to a switch A. Hereby, a main illuminator 2 lights. The microcomputer 13 starts the clocking with an internal timer at the same time when it sends out a lighting instruction signal S20, and when a specified time passes, it stops the sending-out of the lighting instruction signal S20 and closes the switch A and extinguishes a main illuminator 2.

Title: Capacitor motor
Inventor: YAMAZAKI KENJI
IPC: H02P1/44
Filed: 1979-07-10
Abstract: PURPOSE:To improve the reliability of a capacitor motor in operation and the reduction of power consumption by turning on or off a semiconductor switching  element with a signal electrically detecting the conduting state to switch the capacitor capacity at starting time and after acceleration. CONSTITUTION:Since a transistor Tr6 is turned on with its base voltage lowered while a transistor Tr5 is turned off when starting a capacitor motor, a transistor Tr8 is turned on to conduct is thyristor S. Accordingly, an auxiliary winding A is connected to phase dividing and starting capacitors CR and CS. When the motor speed is raised to cause the potential across the winding A to become high so that the detected voltage by a detector 1 exceeds set voltage of constant-voltage diode 9, a current flows through the base of the transistor Tr5 to conduct the Tr5 while turn off the Tr6. Accordingly, the gate signal of the thyristor S is eliminated, and it is thereafter turned off in half cycle of applied AC voltage to automatically isolate only the capacitor CS. In this manner it can improve the reliability in operation of the motor and reduce the power consumption.

At this state the device is evacuated to 10 -7  Torr and adjusted to 10 -3 W10 -4  Torr by introducing N 2  gas. On the other hand, N 2  gas and Ar gas are introduced into a sputtering device in the 1:1 ratio to adjust the device to 10 -1 W10 -2  Torr. Electric power is then supplied to the evaporation source to form a lithium nitride thin film on the substrate by vapor deposition or physical vapor deposition due to sputtering. This film is relatively stable and can be applied to various uses such as the electrolyte of a lithium cell and a sensor.

Title: Multicone type synchronizer
Inventor: ISHIGURO YASUHIDE
IPC: F16D23/06
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent abrasion and seizure caused by biting of a middle ring into an outer ring by forming the outer peripheral edge part in the small diameter side end part of the middle ring into a cross-sectional circular arc shape. SOLUTION: At unoperated time, there is a case where respective rings rotate while inclining in the optional direction in an idly rotating state. In this case, since a middle ring 14 relatively rotating with an outer ring 13 is different in the inclination, the edge part of the small diameter side end part easily hitches on the inner peripheral surface side of the outer ring 13, particularly, a lubricating groove 13d formed on the inner peripheral surface. However, since the outer peripheral edge part 14d corresponding to the small diameter side edge part of the middle ring 14 is formed in a cross-sectional circular arc shape, the outer peripheral edge part 14d of the small diameter side end part of the middle ring 14 does not hitch on the lubricating groove 13d on the inner peripheral surface of the outer ring 13 so as to prevent biting of the moddle ring 14 into the outer ring 13 to thereby prevent abrasion and seizure caused by biting of the middle ring 14 into the outer ring.

Title: Resistance measuring unit
Inventor: SHINDOU SHIYOUTAROU
IPC: G01R27/02
Filed: 1979-07-09
Abstract: PURPOSE: To make read of a display equipment easy and sure, by controlling the current value flowed to a measured resistance into a fixed value independently of the value of the measured resistance in the resistance measuring unit using clip- system transformers for injection and detection.  
     CONSTITUTION: Current Ix flowed to measured resistance Rx is controlled into a fixed value independently of the value of measured resistance Rx by the function of the system including clip-system current transformer CT, clip-system transformer PT, and integrator IG. Consequently, voltage e x  generated across both ends of measured resistance Rx corresponds to the value of measured resistance Rx. This voltage e x  is detected by coil 24 in transformer PT, and the detection voltage is rectified and amplified by rectifying and amplifying circuit RE 2 , and the value is displayed on display equipment DI. Thus, since the output of rectifying and amplifying circuit RE 2  is proportional to the value of measured resistance Rx, the scale proportional to the value of the measured resistance is used when an indicator is used as the display equipment, so that read becomes easy and read error can be prevented.

Abstract: PURPOSE:To absorb a difference between interfaces, a frequency shift due to Doppler effect, and variation in propagation delay time by supplying the transmission/reception timing of the interface on the side of a ground node from the local clock in a satellite earth state, and using an adapter equipped with a buffer in common and synchronizing networks.

Consequently, the frequency shift due to Doppler effect caused by variation in the distance to a stationary satellite and variation in propagation delay time due to a shift in the position of the satellite are both absorbed.
