Title: Camera provided with image blurring prevention device
Inventor: MIYAMOTO HIDENORI
IPC: G03B5/00
Filed: 1994-04-27
Abstract: PURPOSE:To provide a camera provided with an image blurring prevention device capable of sufficiently and appropriately correcting image blurring by constituting a camera so that the speed of a correcting action exceeds tone maximum image blurring speed until at least the image blurring speed becomes the maximum. CONSTITUTION:A driving part whose rising time is shorter than prescribed time is used as the driving part. That means, a sine wave A is the sine wave whose frequency (f) is 10Hz and whose maximum image moving speed Vmax is 7.5mm/s by the camera shake of a beginner, for example. A curve B is the rising characteristic curve of the image blurring prevention device. A fixed point C is a point showing the maximum vibration speed of the waveform A and a fixed point D is the correction speed of the curve B when the waveform A shows the maximum vibration speed. In such a case, the correction speed shown by the fixed point D corresponds to 63% of the maximum correction speed Lmax and exceeds the speed of the sine wave A shown by the fixed point C. Then, the image blurring prevention device provided with a characteristic shown by the curve B can follow the camera shake shown by the vibration waveform A.

Title: Characteristic extracting method, and object recognition device using the method
Inventor: OHASHI KATSUMI
IPC: G06T1/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To execute character extraction processing with high accuracy regardlessly of the position of an object. SOLUTION: An image inputting part 6 takes in an image from a camera that is arranged with its image pickup direction directed to a road, processes it and stores the input image in image memory 7. An image converting part 9 generates a perspective transformation image that is projected on a virtually horizontal plane where image data of each pixel of the input image is set on a road surface. When a characteristic extracting part 10 performs edge extraction processing from the perspective transformation image, an area setting part divides a created edge transformation image into plural small areas of the same size and further groups them by extracting small areas that include the prescribed number of edge configuration points. An object discriminating part 12 collates the size of each group with a prescribed model and discriminates whether the group corresponds to a vehicle or not.

Abstract: PURPOSE:To prevent defective forming by lamination and to improve working efficiency by executing pressurization of a powder raw material by a pressure oil of a large capacity and low pressure in an initial period and by a pressure oil of a small capacity and high pressure in a later period. CONSTITUTION:The pressure oil is put into an upper hydraulic chamber 21 of a sub- cylinder 13 by a hydraulic pump 23 to push down a plunger 20 and to lower an upper die 22. The pressure oil of a hydraulic pump device 3 flows into a small-pressure chamber 35 of a pressure converting cylinder 28 when the upper die 22 actuates a position sensor 66 during lowering of the die 22. This oil presses a piston 31 which delivers the pressure oil lowered in the pressure from a large pressure chamber 36 and feeds the same to the upper hydraulic chamber 21 of the sub-cylinder 13, thereby pushing down the upper die 22 by the lower pressure and pressing the powder raw material. The pressure oil in a lower hydraulic chamber 18 of a main cylinder 12 is then released into an oil tank and the pressure oil of the device 3 flows into a large pressure chamber 36 of the cylinder 28. Then, the pressure oil in the small pressure chamber 35 flows into the upper hydraulic chamber 17 of the main cylinder 12 and pushed down the piston 15, thereby lowering the die 22 and pressing the powder raw material by the high pressure.

Abstract: PROBLEM TO BE SOLVED: To improve the use efficiency of light from a reflection mirror without decreasing the optical characteristics by constituting a side wall part so as to seal the side hole of a concave reflection mirror and to control a light- emitting region. SOLUTION: The light source device for image projection consists of a concave reflection mirror 7 having a spherical, ellipsoidal or parabolic reflection face, a discharge lamp 1 with a small electrode gap assembled in the concave reflection mirror 7, and a side wall part 9 attached to the open end of the concave reflection mirror 7. The side wall part 9 is formed to seal the side holes 8 of the concave reflection mirror 7 and to control the light-emitting region. Thereby, leaking of light from the reflection mirror 7 or decrease in the accuracy of the reflection face can be prevented, and irregularity in a dichroic reflection film formed on the reflection face can be avoided. Thus, decrease in the optical characteristics is prevented and the use efficiency of light can be improved.  Moreover, a front cover can be easily attached without decreasing the optical characteristics and scattering of the broken discharge lamp when the lamp is broken can be prevented.

Filed: 1978-07-25
Abstract: PURPOSE: To stably convey an image carrier and perform good fixing by cooling or heating one end of the fixing roller so that the temperature differnces of its both ends become of a specified range.  
     CONSTITUTION: While copying paper 20 is being conveyed by a fixing roller 31  containing a heater 35 in its hollow part and a backup roller 32 turning in contact therewith, the toner images formed on the copying paper 20 are heat fixed. One end of this roller 31 is controlled by cooling with a fan 44 so that its temperature has a difference of the specified range as compared to the temperature of the other end. As a result, the oblique conveying, zigzag conveying, etc. of the copying paper owing to the temperature differences of both ends of the roller 31 are prevented, the copying paper stably conveyed and the toner well fixed. The similar results are also obtained even by heating one end of the fixing roll whose temperature becomes lower than that of the other end.

Abstract: PURPOSE:To prevent the misoperation of start-up of a motor and the careless opening of a cover in a disk-driving device on whose body a motor for driving a disk and a switch for controlling the power supply to the motor are provided and a cover for covering the upper part of a disk-mounting surface of the body is openably and closably fitted. CONSTITUTION:The operating member 45 for the switch 40 is fitted to the upper wall of the cover 5 so as to unavoidably close the cover 5 when the operating member is operated. Consequently, the disk 3 is prevented from being unexpectedly driven for rotation when the disk 3 is being taken in or out in the state where the cover 5 is left open. An operating knob 33 for releasing the closing lock for the cover 5 is provided on the flank of the body 1. The cover 5 is thus prevented from being unexpectedly opened during the rotational operation of the disk 3 and misoperation due to a mistake of the knob for the operating member 45 for the switch 40 is also prevented, thereby permitting each to be properly used.
