Title: Flexible printed circuit board in double-layer structure
Inventor: ONO YASUHIRO
IPC: H05K1/00
Filed: 1993-12-28
Abstract: PURPOSE:To provide a flexible printed circuit board in double-layer structure which is narrow and is suited for a high-speed signal transmission. CONSTITUTION:In the printed circuit board, ground wire patterns 32 and 32' on the upper and lower surfaces of an insulation strip are zigzaged in the width direction of an insulation material strip, are crossed in an X-shape at a plurality of locations according to the top view, and then these crossed parts are connected by a through hole 5. A plurality of small loops are formed by the ground wire patterns 32 and 32' on the upper and lower surfaces of the insulation material strip and the through hole 5 for connecting them. Therefore, a resonance frequency can be made higher than a signal frequency band, thus achieving a high-speed and high-quality signal transmission.

Title: Power unit for electric automobile
Inventor: SEKIGUCHI TOMIO
IPC: H02J7/00
Filed: 1991-12-09
Abstract: PURPOSE:To facilitate constant-current control and to manufacture a large power source by using small-sized power sources by connecting output current fixed type constant-current power sources in parallel as many as a necessary output current as set and commanded. CONSTITUTION:An input part 1 is a rectification part which converts an alternating current into a direct current, in the case of a down converter being a battery part. Many constant-current power sources 2 are connected in parallel. Further, a load part 3 is connected to various loads such as a motor through a battery and an output current command part 4 indicates the operation and nonoperation of each power source for current value setting. The electric power supplied from the input part 1 is inputted to each constant-current power source 2 and a constant-current power source 2 whose operation is indicated by the output current command part 4 operates to supply its output to the load part 3. The maximum value of output currents becomes the sum of the outputs of constant- current power sources in operation, so the output current maximum value can be set according to how many constant-current power sources are put in operation.

Title: Table form data display method
Inventor: ITO KOICHI
IPC: G06Q10/10
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To display many items of the original data and to improve the working efficiency for the change of the table form data by setting an easy-to-use number of items for a user and displaying a screen over plural display rows or columns. SOLUTION: Every table of a consistent production design system includes many items in each manufacturing process, and accordingly the number of items that can be shown on a single screen is limited and many items overflow the screen. In this respect, only the contents of a specific record are returned at a proper item according to the screen size and therefore a long line can be displayed in plural stages. At the same time, a pull-down menu 20 of 'function' is shown on the screen via a mouse, etc. When 'return' is selected, a window 30 is shown. The current set contents are automatically shown in the window 30 in the 'current set' mode. When a user puts a numeric character '20', for example, in a blank column of 'new set', a screen where the items 1 to 20 of the specific record are included in a single line is shown.

Abstract: PURPOSE:To arrange a plurality of blended material soils previously in a continuous strip-like manner in longitudinally aligned relation to one another and load base material soil uniformly on a conveyor between the blended material soils when the base material soil and a plurality of blended material soils are fed on the conveyor. CONSTITUTION:Hoppers 22 and 24 for feeding blended surface layer material soils are provided at their respective feeding ends with slit-like holes arranged in a few lines in longitudinally aligned relation to one another in order to load the blended material soils from the slit-like holes on the carrying side of a conveyor 28 on a conveyor dolly 26 and arrange the material soils in a strip-like manner in longitudinally aligned position.

Title: Tube type heat exchanger
Inventor: FUKUZAWA KUNIYUKI
IPC: F28F9/02
Filed: 1993-12-28
Abstract: PURPOSE:To eliminate a difference in adhering amounts of a scale and a slime at input and output sides of a heat exchanging tube and to increase the service life of a heat exchanging tube by rotating a partition wall plate in the case of heat exchanging and inverting a flowing direction in the tube. CONSTITUTION:A motor 44 is operated in a heat exchanging operation to rotate a partition wall plate 14. Thus, when a communication hole 38 formed at the plate 14 is moved to a position of an input chamber 20A, a communication hole 40 is disposed at an output chamber 20B. On the contrary, when the hole 38 is disposed at the chamber 20B, the hole 40 is disposed at the chamber 20A. That is, the plate 14 is rotated thereby to alternately switch an input side and an output side of a heat exchanging tube 36. Accordingly, since a flowing direction of heat source fluid 21 flowing in the tube 36 is periodically inverted, a difference of adhering amounts of scale, slime at the input side and the output side of the tube 36 can be eliminated. Further, since a back washing effect is generated, the scale, etc., adhered in the tube 36 can be reduced.

Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To enhance an image grade by providing a correction means preventing the expanse of light in the direction right-angled to the arranging direction of the image elements on a permeation type image element substrate. SOLUTION: A half mirror 8 is arranged at 45 deg. with respect to image element substrates 2, 4 and these substrates 2, 4 are set so that the main surfaces thereof become mutually right-angled. One surfaces of prisms 16, 18 having a right- angled isosceles triangle are bonded to the upper and rear surfaces of the half mirror 8 by an adhesive composed of a transparent epoxy or acrylic resin. The other surfaces of the prisms 16, 18 become parallel to the main surface of a permeation based image element substrate or the main surface of a reflection based image element substrate 4. By this constitution, the light from the permeation based image element substrate 2 enters the prism 16 at a right angle. Therefore, laser beam does not expand at the incident interface of the prism 16 and advances straightly as it is to enter the glass plate 14 of the half mirror 8.

IPC: H03M1/10
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To estimate distortion due to the linearity error of an A/D converter having linearity errors.
