Title: Manufacture of ic package
Inventor: TAKENAKA MASAJI
IPC: H01L21/56
Filed: 1990-03-20
Abstract: PURPOSE:To strengthen the bonding power to a sealing resin, to prevent moisture form creeping, to prevent a migration from being caused by the moisture and to prevent the sealing resin from being cracked by a method wherein the surface of a flexible printed circuit board or a carrier tape for tape-automated bonding use is roughened. CONSTITUTION:The face, on which patterns such as leads or the like are not formed, of a carrier tape 3 is roughened by a chemical method or a mechanical method. A chip 7 is mounted on the carrier tape 3 whose surface has been roughened; it is sealed with sealing resin 8 in such a way that leads 5 are exposed partially. Alternatively, the leads 5 are bonded or soldered to a lead frame 9. After that, the tape carrier 3 on which the chip 7 has been mounted and parts of the lead frame 9 are sealed with the sealing resin 8. Thereby, the bonding power of the carrier tape 3 to the sealing resin 8 is enhanced. Consequently, moisture does not creep into a package; it is possible to prevent a migration from being caused and to prevent the sealing resin from being cracked.

Title: Planetary gear shift gear
Inventor: TSUKAMOTO KAZUMASA
IPC: F16H3/66
Filed: 1989-03-20
Abstract: PURPOSE:To prevent the effect of the centrifugal oil pressure by using at least one of multiple coupling elements controlling shift actions of four planetary gear mechanisms as a friction clutch coupled or released while the side where an operation piston is provided is kept at the stop state. CONSTITUTION:The fourth clutch 34 is coupled or released at the time of a shift from the first speed to the second speed or vice versa. Since a drum section 341 side having the piston 342 of the fourth clutch 34 is kept at the stop state in this case, no centrifugal force is applied to an operating medium in a cylinder chamber 343. The fourth clutch 34 is kept at the coupled state and the stop state in the second speed state, thus no centrifugal force is applied to the operating medium in the cylinder operating chamber 343, no residual pressure by the centrifugal force is generated when the static pressure in the cylinder operating chamber 343 is discharged at the time of a down-shift, and no dragging occurs. The adverse effect by the centrifugal force can be surely prevented accordingly.

Filed: 1989-03-20
Abstract: PURPOSE:To prevent the generation of a crack which is generated in the relief hole parts of metal plates by a method wherein after a filler containing hard inorganic materials is filled in the relief hole parts, the plates are laminated by hot press. CONSTITUTION:A metal plate 1, such as a copper plate or an Al plate and the like, is subjected to relief hole work and thereafter, the plate 1 is oxidized or roughened its surface, is pinched between prepregs 2 and is hot-pressed along with a copper foil on its surface. A process in which after a filler 4 connecting hard inorganic materials (foaming glass powder) 4a is filled in a relief hole part 11, the metal plates are laminated by hot press, is contrived so as to be included in the manufacturing method of the title board. Accordingly,the materials 4a being contained in the filler 4a are equally dispersed in a resin, which soaks in the part 11 by hot press, of the prepregs 2. Thereby, a shrinkage stress works equally at the time of shrinkage of the resin and the generation of a crack can be prevented.

Title: Parabolic antenna for circular polarized wave
Inventor: URASAKI SHIYUUJI
IPC: H01Q1/42
Filed: 1983-04-19
Abstract: PURPOSE:To obtain a low-cost antenna reduced at its performance deterioration by setting up a circular polarized wave generator enabled to save the parts of a wave guide, constitute a blocking only by the center part of a parabola and improve its voltage standing wave ratio. CONSTITUTION:Since the output end of a down converter 6 has a normal square waveguide, a pyramid horn 9 can be directly connected to the output end and a converter can be made unnecessary. Straight polarized waves from the pyramid horn 9 are converted into circular polarized waves by the circular polarized wave generator 10, reflected to the parabolic antenna 1 and radiated to the space. The circular polarized wave generator 10 is constituted by a glid 14, a dielectric plate 12 and a metallic plate 13. The direction of the glid 14 is inclined from the polarized wave direction of incident wave E from the pyramid horn 9 by 45 deg.. The thickness of the dielectric plate 12 is 2t near the center axis of the horn and (t) at the periphery. The neighborhood of the horn center axis contributes to the standing wave ratio of the pyramid horn 9, and if it is defined that 5=lambda/ 8.gammaxsi<1/2> (xsigamma: specific inductive capacity), radio waves returned from the glid 14 and the metallic plate 13 to the pyramid horn 9 are phase-reversed at the neighborhood, so that the voltage standing wave ratio is improved.

Abstract: PROBLEM TO BE SOLVED: To precisely check amount information of a prepaid card and to prevent consumption information recorded in readers/writers from being increased even if the amount information is polled in a repeater from the plural readers/writers in any order. SOLUTION: Amount information of an IC card 2 is sequentially consumed in the order of readers/writers 1A, 1B and 1C. The amount information of the IC card 2 is up-loaded (polled) on a repeater 4 in the order of the readers/ writers 1A, 1C and 1B. Whenever the amount is consumed, card ID, a ticket face and history information of the balance are recorded in the IC card and card information is generated. Card information is read by the respective readers/writers and it is irregularly polled by the repeater 4. The repeater 4 sequentially compares the balances of items corresponding to card information 3A which is previously received and is stored with card information 3C which is received next. When the balances are matched, a flag is raised only by one time in the balance of the last item and a raised state is continued.

Filed: 1994-04-07
Abstract: PURPOSE:To make the processing speed of jaggy processing sufficiently follow up the travel speed of a pen by arranging gradation data at the periphery of a segment on a side where a step is eliminated. CONSTITUTION:When the pen 105 is operated to run on a tablet 110, drawing input is performed through a drawing input means. Once the drawing input is performed, a coordinate value detecting means detects the passing position of the pen 105 in the form of coordinate values. The coordinate values as detection results are connected with drawing data of a segment sequence. The step part between adjacent segments is detected by a step detecting means by using a staircase-shaped segment. At the periphery of the segment on the side where the step is eliminated by arranging drawing data at the periphery between the two adjacent segments forming the step, gradation data are arranged by a gradation data arranging means. When the gradation data are thus arranged at the periphery of the segment of the drawing data, a display means performs display processing on its display screen 180.
