Filed: 1993-11-04
Abstract: PURPOSE:To prevent side slip of leads, twists, and bonding failure by protrudingly enlarging the width in an inner lead bottom corresponding to the bonding area on an inner lead top. CONSTITUTION:An inner lead bottom corresponding to the bonding area 2 on an inner lead top having a width enough to secure the bonding area 2 is provided with a projection 5 in the width direction of a lead.

IPC: G10L15/06
Filed: 1990-10-15
Abstract: PURPOSE:To generate oscillation or endless period chaos and to form a natural deformation pattern reflecting human's pattern recognizing capacity by using a three-layer feedback associative storage model for selecting a non-linear function. CONSTITUTION:An input pattern and a feedback signal are stored in an input register 21 and supplied to the succeeding step by an output from a clock oscillator 22. A differential operation part 24 obtains an intermediate layer output from values supplied from respective sum of product computing parts 23, 26, a threshold processing part 25 executes the threshold processing of the output from the differential operation part 24 and then multiplies the processed result by a weight matrix and the 3rd sum of product computing part 27 executes the processing of the multiplied result. The processed result is stored in an output register 28. Consequently oscillation or the like can be generated by selecting a non-linear function in the processing part 25 and a natural deformation pattern reflecting human's pattern recognizing capacity without following specific probability distribution can be formed.

IPC: B05B1/02
Filed: 1992-10-14
Abstract: PURPOSE:To carry out roasting to be transformed into stable ferrite by dispersing sprayed current, lowering the colliding energy of the current, and atomizing the liquid drops. CONSTITUTION:The tip of a nozzle 7 is slitted (the number of the slits is 2-4) and tips of nozzles 7 are arranged at random, so that the slits of each nozzle are not positioned at fixed positions. To arrange them at random, the angle thetaof each nozzle is set to be within a range defined as {(360 deg./n)/N}>=theta>=2 deg. wherein N stands for the number of the nozzles and is 3-12; n stands for the number of the slits and is 2-4. By setting the angle theta to be within the range, the colliding currents of the liquids sprayed from nozzles are dispersed while being not converged into one point and thus the liquid drop currents are made to be fine. As a result, roasting for transformation into stable ferrite can be carried out and consequently, the quality of soft ferrite products is improved.

IPC: B60P1/44
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To handle a cargo between a ground and a cargo bed and to prevent a ramp device from disturbing a direct cargo handling between a platform and the cargo bed, by mounting a loading table lifting among a height of the cargo bed, its same position, and a position abutting to the ground on a slide rail connected with a lower part of the cargo bed. SOLUTION: For handling a cargo between a cargo bed and a ground, upper surfaces of a base portion 41 and an end 42 of a loading table open so as to be a same horizontal plane, and the loading table 4 is lifted up and down between the ground and a height of the cargo bed. When a ramp device is not used, the end 42 of the loading table is folded on the base portion 42 of the loading table, an arm substrate is moved to the rear end in a slide rail 1 with keeping a lifting arm 3 horizontal, and most of the folded loading table 4 is evacuated under the cargo bed. In this state, a cargo handling vehicle is moved up to just before the loading table 4 abuts to the front side wall of a platform and is stopped, and handling of the cargo is performed. Thus, the lifting of the loading table 4 assists the handling of the cargo between the cargo bed and the ground, and the loading table 4 does not disturb work when in no use.

Title: Hydraulic composition
Inventor: NAKANE ATSUSHI
IPC: C04B28/02
Filed: 1991-09-30
Abstract: PURPOSE:To improve the brittleness of a high strength concrete by suppressing the generation of microcracks by relaxing concentration of stress on the boudarys between water hardened powders of cement particles, etc., and fine powders, while securing a high strength of the water hardened composition. CONSTITUTION:Cement 1, silica fumes 2 and water are charged in a mixer and a polymer of superfine particles 3 is added at the same time as the deposition of the first water. They are kneaded and then a high performance water decreasing agent 4 and the remaining water are added to mix and later the agitation is interrupted. The reason that the agitation is interrupted like this after the high performance water decreasing agent 4 is added, is because the cement particles 1, the silica fumes 2 and the polymers 3 filling the spaces between those are settled and there surfaces are perfectly coated with the high performance water decreasing agent 4. Then, an aggregate is added and they are kneaded.

Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a digital camera constituted so that a finder can be variously used. SOLUTION: A half mirror which can be turned upward is obliquely arranged on an optical path leading to an imaging device from a photographing lens. Then, light reflected on the half mirror is guided to the optical finder arranged above the half mirror. A picture photographed by the imaging device is displayed at a liquid crystal display. Then, the change of the optical path leading to the imaging device from the photographing lens occurring whether the half mirror is positioned on the optical path or not is corrected by changing a position of the imaging device or a position of the photographing lens so as to always make the incident state of light made incident on the imaging device or the length of the optical path leading to the imaging device from the photographing lens constant. Both of a picture formed by the optical finder and the picture displayed by the liquid crystal display properly show an image forming state on the imaging device whether the half mirror is positioned on the optical path or not.
