Title: Color printer system
Inventor: EBIHARA EIICHI
IPC: H04N1/48
Filed: 1988-07-08
Abstract: PURPOSE:To prevent a moire fringe without severely requiring the accuracy of a printing position in a printing mechanism part by applying pre-processing to inputted printing data to impart shift different at every color and imparting predetermined different offset at every color printing. CONSTITUTION:For example, four points (shown by a 'black round mark') of adjacent pixels in printing data are set to (0, 0), (1, 0), (0, 1), (1, 1) and the positions of the printing points of respective colors are set to Y, M and C shown by a 'white round mark'. At this time, the density to be given to each color is determined as the sum of the values obtained by multiplying the densities of respective colors at four points by counting due to a distance. A printing data pre-processing means 1 calculates the data to be given to the image forming means of each color from the printing data inputted by the above mentioned method. In a printer of each color, control is preformed so as to give offset in a line direction to an image forming position corresponding to the printing point position of each color by a printing position control means 2 and a timing control means 3 performs control so as to impart offset in an up-and-down direction to the printing position of each color printed on paper. By this constitution, even when the printing point of each color is shifted, no adverse effect is exerted on the color of an printing result.

CONSTITUTION:A shock absorber 1 has its first liquid room 19 and its second room 21 connect together also by a sub-channel 41, and the channel is opened and closed by an opening/closing mechanism so as to change its damping force. In order to close the sub-channel 41, which is opened, operative force which is generated during relative movements of a cylinder 3 and a piston 17 is exerted on the valve body 73 of a sliding valve 71 to remove the same and then a controlling channel 91 is opened during the stretching speed of the shock absorber 1 being zero or low so as to release the liquid room 57 of a poppet valve 51 from its condition under which it is filled up with liquids. Thus the valve 51 has its valve body 53 moved by the force of a spring 56, and oil is introduced into the liquid room 57 via the controlling channel 91, simultaneously, for promptly closing the sub-channel 41; therefore, its low damping force is changed into high damping force.

IPC: G03G15/00
Filed: 1989-07-05
Abstract: PURPOSE:To preclude misdetection due to a noise while holding necessary irreducible pattern width by referring to input data from a detection means as to a specific threshold value at specific reference intervals, and deciding the pattern head from the appearance rate of the referenced value reaching a pattern detection level. CONSTITUTION:A photosensitive body 3 is exposed to a pattern which has reference density to form a latent image or developed pattern on the photosensitive body, and its surface potential or density is detected by the detecting means 1. Then the input data from the detecting means is referred to as to the specific threshold value at the specific reference intervals and when the referenced value indicates a pattern detection level twice successively as to the specific threshold value, the appearance rate of the pattern detection level as to a specific reference quantity is calculated including the two referenced values. When the appearance rate is larger than a specific rate, the head of the specific reference quantity is regarded as the pattern head. Thus, the pattern head part is prevented from being misdetected owing to a noise.

Filed: 1992-06-30
Abstract: PURPOSE: To surely use a device even at a high voltage by providing a means for increasing breakdown voltage between an island-shaped area and an adjacent semiconductor separate area in a semiconductor device. CONSTITUTION: A breakdown voltage increasing means is provided not only to a horizontal extended part 40 of a separate area 4 but also to a p-type area 41 being a means adjacent to the surface. The p-type area 41 is arranged in an island-shaped area 3, and these p-type areas form a narrow ring completely surrounding a contact pad 6 in the island-shape area 3. An isolated distance λbetween the p-type areas 41 and between the p-type area 41 and the extended part 40 is set about 6μm sufficiently short enough to allow depletion areas in the surrounding of the surfaces area 41 and a p-n junction 34 to overlap each other in an operation. Thus, the depletion area in the surrounding of the p-n junction 34 is further extended on the surface so that electric field intensity in the depletion area can be further dropped.  Thus, the breakdown voltage of the p-n junction 34 can be further increased. Thus, the p-n junction of the device can withstand voltage higher than 1400V.

Title: Method for judging adequacy of volume of container
Inventor: KATAYAMA MASAYOSHI
IPC: G01F17/00
Filed: 1984-08-20
Abstract: PURPOSE:To judge the adequacy of the volume of a container accurately, by resonating the container at the resonance frequency of the container, and computing the volume of the container based on the detected signal of the resonance. CONSTITUTION:When a vibrator 2 is swept in a specified frequency range, a container 3 is resonated at the resonance frequency of the container 3. The resonance is detected by a sensor 8. Based on the detected signal, the resonance frequency is obtained by a signal processor 10. The volume of the container 3 is computed based on the obtained resonance frequency in a microcomputer 11. The adequacy of the volume as to whether the volume is within an examination reference value or not is judged. In this method, remaining of water in the container and the contamination of the inside due to use of water in the conventional method can be prevented. Thus the adequacy of the volume of the container can be automatically judged accurately.
