IPC: G03B7/16
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a camera equipped with a lamp unit having light distribution characteristic extended in the width direction of a scene without making the lamp unit larger. SOLUTION: The lamp unit provided in the camera equipped with a stroboscope and an automatic focusing mechanism is equipped with a tungsten lamp 41 constituted by linearly disposing a filament 42 in a glass bulb 44, a reflector 46 condensing the light of the lamp 41, and a front panel 47 attached to the front of the reflector 46. The lamp 41 has such a light emitting area that sufficient light quantity is extended over the longitudinal direction of a photographic plane(image) and the light distribution characteristic fit to the longitudinal direction of the image is given without making the lamp larger. As a result, not only a red-eye preventing effect on the periphery of a frame but also focusing ability at a peripheral range-finding part are improved.

Title: Optical projection exposure device
Inventor: SASE YOSHIMITSU
IPC: G01B11/00
Filed: 1991-12-26
Abstract: PURPOSE:To correct the chromatic aberration with high accuracy and reduce out-of-focus conditions in the image formation position in each wave band by dividing the wave band of reflected light from an alignment mark. CONSTITUTION:White lamp light from an alignment light source 22 is applied to a band path filter 19. It is limited into light of a specified broad wavelength width. Then the light passes through a projection lens 2 by means of an illumination lens 18 and a half mirror 13 and is applied to an alignment mark 4. Reflected light from a wafer 3 passes through the projection lens 2 and a take-in mirror 11, and forms an image of the alignment mark 4, entering an objective glass 12. The light is turned into parallel rays of light and divided by means of a wavelength separation mirror 14 by wavelength ranges, being applied to image formation lenses 151 and 152, respectively. The images are magnified through magnification lenses 161 and 162, respectively, and formed on optical detectors 171 and 172 again. This corrects the chromatic aberration with high accuracy and reduces out-of-focus conditions in the image formation position of each wave band.

Or the longitudinal acceleration of a vehicle is directly measured and monitored, and when the absolute value exceeds 0.03g, the rotational angular velocity of each tire may be nullified. The rotational angular velocity of each tire may be nullified when a brake pedal is depressed. On the other hand, the throttle opening is measured and differentiated, and when the monitored differential value exceeds 100%/sec., the rotational angular velocity of each tire is nullified.

Title: Semiconductor device and its manufacture
Inventor: TOMINAGA ATSUSHI
IPC: H01L21/331
Filed: 1991-12-26
Abstract: PURPOSE:To completely prevent the deterioration of electric characteristics due to the influence of water content or the like permeating from the outside, by forming a silicon nitride film and a titanium oxide film wherein the density of the film itself is higher than a silicon oxide film, on the side wall of a polycrystalline silicon layer. CONSTITUTION:After a metal wiring layer 11 is formed, an SiN film 21 as an insulating film and an SiO film 14 as an interlayer insulating film are formed in order on an insulating film 8 containing a polycrystalline silicon layer 10 and a metal wiring layer 11 of a first layer, by using a plasma CVD method. Since the polycrystalline silicon layer 10 forming an emitter leading-out electrode is covered with the SiN film 21 as an insulating film, the polycrystalline silicon layer 10 does not directly come into contact with the SiO film 14 as an interlayer insulating film, so that the deterioration of electric characteristics due to the influence of water content or the like permeating from the outside can be completely prevented. Thereby the reliability of a device can be improved.

Abstract: PROBLEM TO BE SOLVED: To accurately determine the correctness of eyeglasses by measuring the refractive ability of a subject's eyes while the subject is gazing into a distance with both eyes wearing glasses. SOLUTION: The refractive ability is measured while the subject is gazing into a distance with both eyes wearing glasses. When it is recognized that his eyes are set in position, a light source 25 with an intense light is turned on and the light is reflected from the eyeground. If a disturbing light comes in from a path in front of his eyes, the path is blocked with a shutter 16. The light reflected from the eyeground goes through lenses T of the glasses and is reflected from a dichroic mirror 8, 11, through an objective lens 19, from a mirror 20, a pierced mirror 21, through a diaphragm 28, a deflection prism 27, a lens 26, from a dichroic mirror 17 into a means for imaging as luminous flux with a ring shape. The video signal is taken into a means for the arithmetic operation and values of refraction including astigmatism are found from the dimensions and the ovality of the ring.  The reflected light of the measured luminous flux, which retraces a path O1 through this lens T, goes along a path O2 and is cut off with a shading material of a film 17a for the total reflection and the refractive ability is accurately measured even if the subject has the glasses with the lens T on.

Title: Cell tone image data converting method
Inventor: MATSUSHITA KAZUHIRO
IPC: H04N1/46
Filed: 1993-12-22
Abstract: PURPOSE:To make a boundary line clear and to reproduce an image close to the original cell tone image by forcedly replacing a less-frequency color with a highest-frequency color without sampling a part where a numerical value is not stabilized. CONSTITUTION:The color of light is delicately changed corresponding to the degree of brightness to mix three colors of red (R), green (G) and blue (B). The gradation data of primary colors are converted so that the color number in cell tone image data can be subtracted to the number of colors to be expressed by a target computer device. Since the gradation-changed data are data corresponding to the number of colors to be reproduced, in order to prepare final data, the color number is further decreased to the color number to be simultaneously generated by sampling the data. In this case, the part where the numerical value is not stabilized is not sampled for the unit of a character but the less-frequency color is forcedly replaced with the highest-frequency color, and the colors are subtracted by performing sampling to investigate the frequency of colors to be used.

Title: Servo motor position controller
Inventor: ANIYA MASAHIRO
IPC: G05D3/12
Filed: 1991-12-27
Abstract: PURPOSE:To facilitate the design of a servo system and to easily realize an optimum response by limiting the width of an integrating operation at an integral compensation part. CONSTITUTION:A moving position signal theta(t) of a servo motor 1 is detected by a potentiometer 3, a position feedback signal and velocity feedback signal are compared with a target input Vin by a deviation calculation part 5, and deviation is calculated. The calculated deviation is inputted through an amplifier 6 to an integral compensation arithmetic part 8, and the servo motor 1 is controlled through a driver 7 with the output. Since the output of an integrator composed of an operational amplifier at the integral compensation part 8 is limited, the integrating operation is not executed but only the proportional operation and the differential feedback operation are executed when the target input Vin and the moving position signal theta(t) are deviated more than the width of a dead zone. When a moving position is made close to the target input Vin and the deviation enters the dead zone, the integrating operation is started. By limiting the width of the integrating operation at the integral compensation part, the design of the servo system is facilitated and the optimum response is easily realized.
