A damage detecting device according to one aspect of the present invention comprises a first speed generator, a second speed generator, a first waveform shaping section, a second waveform shaping section, and a determining section. The determining section compares a second rectangular wave shaped by the second waveform shaping section and a first rectangular wave shaped by the first waveform shaping section and, if the first rectangular wave is not output while the second rectangular wave is output, determines that a supporting device for an armature shaft is damaged or worn.

An open/close control system for an inspection lid adapted not to open while a vehicle travels. An emergency release device is provided behind the inspection lid, where the emergency release device disables power transmission of a driver which opens and closes a side entrance/exit door of a railway vehicle. The emergency release device is installed in a space inside a wall surface inside the vehicle, and the space can be opened and closed by the inspection lid. The open/close control system has a locking device provided in the space inside the wall surface in order to restrict rotation of the inspection lid, and also has an open/close controller which detects traveling of the railway vehicle to actuate the locking device.

The present invention allows a thumbnail display representing the outline of input images in a digital image printer to be made, in which it is determined whether an image is a first kind of image or a second kind of image, and if it is determined that the image is the first kind of image, a feature part of the first kind of image is enlarged in the thumbnail display to make the contents of image more understandable. Also, the invention allows a thumbnail display representing the outline of input images in a digital image printer to be made, in which it is determined whether an image is a character image or a gradation image, and if it is determined that the image is the character image, a part of the character image is enlarged in the thumbnail display to make the characters more understandable.

Image processing apparatus, image processing method and computer program

In an image processing method and apparatus, image data having multi-value levels for one pixel is input, and the input image data is quantized such that an output area of one pixel is adapted to an output device in which an output area of one pixel changes depending on the position of the pixel. A quantizing process executes an arithmetic operation based on an algorithm of a neural network on the basis of a value obtained by multiplying an output value by a weight corresponding to an area of each pixel. Therefore, even if pixels have different maximum luminances, the different numbers of bits, and different color expression capabilities, an optimum half-tone process can be performed by an algorithm based on a cellular neural network, and a high-quality image can be obtained.

Image processing method and apparatus

Taking into consideration the disadvantage that a large-scale analog neural network cannot be constructed as an LSI and, even if this were possible, the cost would be prohibitive and the network would lack universality, a digital image processor for processing input image data based upon a cellular neural network is provided with a first multiply-and-accumulate arithmetic unit for digitally processing multiplication and accumulation of input image data of a plurality of pixels and input weighting values in a predetermined area, a second multiply-and-accumulate arithmetic unit for digitally processing multiplication and accumulation of output image data of a plurality of pixels and output weighting values in a predetermined area, and a non-linear acting unit for deciding output image data in accordance with results of calculation from the first and second multiply-and-accumulate arithmetic unit and non-linear characteristic parameters. This makes it possible to realize an image processor which excels in universality, ease of control and ease of integration.

An image forming method and apparatus which forms an image by using PWM to properly reproduce tones at a low density in the image formation, and attain a high-quality image without reducing the resolution in the dot formation corresponding to a high density value. A color laser beam printer using the PWM to which the present invention is applied forms a latent image onto a photosensitive drum by the laser beam irradiated from a semiconductor laser. The waveform of a chopped wave signal used in the PWM is set to be unique with respect to each color component, and be asymmetrical to the center of each pixel represented by the image signal in synchronization with the waveform of the chopped signal. Accordingly, the interval of dots formed to correspond to each color component is relatively wide when the density value is small, while the interval is relatively narrow when the density value is large.

An electrophotographic system is constituted by an electrophotographic photosensitive member, a charger for charging the photosensitive member to a potential, and an illuminator for illuminating the charged photosensitive member with a light beam to form an electrostatic image thereon. The electrophotographic photosensitive member has a potential-exposure energy characteristic providing an induction energy and a gamma valve varying depending on an electric field intensity induced by the charged potential. The electrophotographic system further includes a controller for controlling the charged potential on the photosensitive member corresponding to resolution and gradation data of an original, so as to optimally reproduce the resolution and gradation, as desired, of the original.

A static pressure gas bearing is incorporated in a housing wherein a slotted groove with a small volume and a throttling control valve are positioned close together. Compressed gas is injected onto the bearing surface from the slotted groove. This configuration provides a static pressure gas bearing in which it is difficult to develop self-induced vibration.
