IPC: G03G15/09
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent toner from being leaked outside a developer tank even when it is scatted on the inside of the developer tank and to obtain a high- quality image without surface fogging by arranging a seal member on a more downstream side than a developing area in the moving direction of magnetic developer. SOLUTION: The seal member 8 is formed of polyethylene terephthalate so as to be like a plate, for example. Then, one end thereof is fixed to the upper side surface of the developer tank 1 and the free end thereof is elastically brought into contact with the surface of the magnetic developer 2 attracted to the surface of a developing roll 3 on the more downstream side than the developing area in the moving direction of the developer 2. A scraping member 7 is formed to be like a round bar and proximately arranged to the roll 3 on the downstream side of the seal member 8. By forming a magnetic brush by directly attracting the developer 2 in the tank 1 to the surface of the roll 3 and rubbing an electrostatic charge image formed on the surface of a photoreceptor drum 4 by the magnetic brush, the high-quality image without density irregularity is obtained.

Title: Cover opening and closing device of keyboard musical instrument
Inventor: OGURA MICHINORI
IPC: G10B3/00
Filed: 1990-09-14
Abstract: PURPOSE:To preclude an entanglement phenomenon by providing a pantograph mechanism constituted by intersecting a couple of belt plates, which have fulcrums of rotation at the mid-points and are in the same shape, with each other at the fulcrum positions. CONSTITUTION:The couple of belt plates 63a and 63b which have the fulcrums of rotation at the mid-points and are in the same shape are coupled rotatably while made to cross each other at the fulcrum positions. Namely, the angle of intersection of the couple of belt plates 63a and 63b is invariably equal at opposite positions, so when a keyboard cover 41 is placed in opening/closing operation in a right-angled direction in the length direction of long holes 45a and 45b, and 57a and 57b connecting two places of the front ends of the couple of belt plates and the two places of the rear ends, the movement quantity becomes equal between both end parts of the keyboard cover 41. Therefore, even when one of both end parts of the keyboard cover is held in the hand and opened or closed quickly, the keyboard cover never slants. Consequently, the entanglement phenomenon is precluded.

Title: Electronic control suspension system
Inventor: TANAKA TADAO
IPC: B60G17/015
Filed: 1984-11-21
Abstract: PURPOSE:To reduce a reactive shock in time of sudden steering, by opening an interconnecting control valve at a time when a steering wheel exists in the return side and a steering angle is large enough, while constituting this valve so as to be closed when it returns to being neutral within the set time and a car speed is more than the specified value. CONSTITUTION:A steering angle 42 of a steering wheel 43 and a car speed 41 are inputted into a controller 36 together with other control information data. At the controller 36, relative size of a steering direction, a position to a neutral position of the wheel and the steering angle are all judged. In consequence, when the wheel 43 exists in the return side and the steering angle is large enough, interconnecting control valves 241 and 242 are opened and simultaneously a timer is set. When the wheel 43 reaches to being neutral within the timer elapse and the car speed 41 at that time is more than the specified value, these valves 241 and 242 are closed for the specified time long. With this constitution, a reactive shock in a car body in time of sudden steering is reducible.

Title: System for compressing picture by setting fixed bit rate
IPC: H04N19/186
Filed: 1992-09-14
Abstract: PURPOSE: To stabilize the quality of a picture by classifying a signal to a class in accordance with the variation of an original picture and controlling a quantization step size by the classified class and keeping the bit quantity fixed for each class. CONSTITUTION: A block division means 20 divides a signal from a color signal separation means 10 by a prescribed unit and outputs the signal to a DCT converter 30 and a variation detecting and class classifying means 50. The means 50 detects the variation of the signal and classifies it to a pertinent class by the detected variation. A multiplier 90 multiplies the output of an SF setting means 60 and a signal from a quantization table to generate a quantization step size and outputs it to a quantizer 40 to quantize it. A bit adjustment part 80 discriminates whether the number of bits of a block passing the quantizer 40 is proper for the number of assigned bits from the means 50 or not to repeatedly adjust block bits until it is proper. After adjustment, the block is outputted to an entropy encoder 100 to obtain encoded data.

Title: Working device
Inventor: YAMAGUCHI SHUICHI
IPC: B30B15/32
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To surely move a part subjected to a working treatment from a working stock toward a downstream side. SOLUTION: A part 12 cut by a cutter 58 is surely placed on a belt 68 by the dead weight of the part 12 via an inclined face 18. That is, because the part 12 is surely placed on the belt 68, the part does not fall out of the belt 68 or is not left on the die 16 as was usual in a conventional practice. Accordingly, there is no need for a handling time to recover the part which has fallen outside the belt 68 or crushed with the dies 16, 52, and the work efficiency is improved. Further, the parts 12 cut by the cutter 58 are not required to be blown by air, and, as soon as the part 12 is completed, the part 12 falls naturally on the belt 68, thereby improving work efficiency.

Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To provide an attaching structure for infrared receiver which can enhance the appearance of an infrared receiver, can reduce the occupying space of the receiver, and can improve the light reception sensitivity of the receiver. SOLUTION: In an attaching structure, grooves 3 and 4 engaged with screws 6 attached to a wall surface 6 are formed on a bottom face 2a of a main body 2 of an infrared receiver. In a state in which an infrared receiver A is attached to the wall surface A by engaging the grooves 3 and 4 with the screws 7, the attaching structure cannot be seen from the outside.
