Title: Control system of magnetic disc device
Inventor: TAKESHITA NOBUYOSHI
IPC: G11B20/12
Filed: 1983-12-26
Abstract: PURPOSE:To attain re-formatting while recovering defective information even at a site where a magnetic disc device is used by storing a nonvolatile memory possible for write in the magnetic disc controller. CONSTITUTION:When a DKC10 receives an instruction to store defective information recorded in a DKU11 from an HOST12, the DKC10 reads a track ID section or an HA section and stores the signal to a RAM17. Then a control CPU2 discriminates whether or not the defective information in the HA section or a flag F of the ID section exists the defective information and if the defective information exists, the defective relating information is stored to a RAMII8. If the defective information of the DKU11 is destroyed due to any cause, the control CPU2 reads the defective relating information from the RAMII8 and reformating is conducted while being written to the ID section or the HA section. Thus, the DKU11 attains reading again.

Abstract: PURPOSE:To make a device small-sized, light-weight, and low-cost by adopting a driving mechanism consisting of the first and the second gears to perform the tape loading operation and the device operation mode switching operation with one driving source in a simple constitution with respect to a cassette video tape recorder. CONSTITUTION:When a cassette setting is detected by a switch, a loading motor 80 is rotated forward and rotation is transmitted to a gear 55. At this time, movement of the gear 55 to a shaft 57 is stopped by a detent arm 82. Therefore, rotation of the gear 55 is transmitted to a gear 54, and a loading ring 40 is turned clockwise through a pinion gear 52. As the result, a magnetic tape 34 is led out to the outside of the cassette gradually in accordance with movement of a guide post 44a. When the loading motor 80 is rotated forward furthermore after completion of loading, the gear 55 is moved more by screw effects of gears 54 and 55 to press-fit a pinch roller to a capstan. Said gear 55 is slid to set the quick traversing mode and the rewinding mode between the loading completion mode and the pinch press-fitting mode.

Title: Aluminum-coated plate for hot-water or high-temperature-steam treatment
Inventor: TOYOSE KIKURO
IPC: B32B15/08
Filed: 1987-10-01
Abstract: PURPOSE:To obtain an aluminum-coated plate for hot-water or high-temperature- steam treatment, which is corrosion-resistant or chalking-resistant and also well forming-processable, by satisfying a specified relationship among the surface roughness expressed in centerline average roughness, the amount of coating and the coating density. CONSTITUTION:An aluminum-coated plate for hot-water or high-temperature- steam treatment satisfies that the relationship among the surface roughness R (mum) expressed in centerline average roughness, the amount of coating W (g/m<2>) and the coating density g (g/cm<2>) is represented with W/g>=R and also satisfies 10>=W/g>=0.1. Making the surface roughness R smaller by making W/g>=R, W/g can be smaller, the amount of coating is economized and also an aluminum-coated plate excellent in corrosion-resistance is obtained. Further, by making 10>=W/g>=0.1, the forming-processability of the aluminum-coated plate is improved. If W/g is 10 or more, the forming precision or the workability is lowered, and if contacted with hot water, etc., the coat becomes whitely turbid due to trapped water in the coat and not favorable in the view-point of appearance. If W/g is 0.1 or less, a problem occurs in corrosion resistance.

When conductive balls are mounted on a curved CSP(chip size package), because the ball holding surface 14 has the shape approximately conforming to the mounting surface, all the conductive balls vacuumed to the vacuum chuck holes 12 in the ball holding surface 14 make contact with an adhesive substance on the mounting surface of the electronic component substantially at the same time as they are mounted thereon, and therefore the misalignment of the conductive balls is prevented. The holding surface is thereby made easier to work and can be manufactured at a lower cost.

Abstract: PURPOSE:To simplify manufacture of a printed-circuit board by forming an electrolytic deposition adhesive containing a fine powder which is turned into a particles by mixing a cation resin obtained by adding amine to an epoxy resin, an epoxy resin, and a curing agent. CONSTITUTION:A fine powder whose grain diameter measures approximately 1-5mum which is obtained by mixing a cation resin obtained by adding amine to an epoxy resin, the epoxy resin, and a curing agent for forming particles is used. The amount of fine powder is adjusted so that it is 0.5-10 times larger than the cation resin in terms of wt.% and a total solid content amount is 10-25%. Electrolytic deposition at a liquid temperature of 20-25 deg.C and a voltage of 5-30V for 10-30 seconds enables a uniform insulation layer and an adhesive layer which is 10-50mum in thickness to be formed. Direct electrolytic deposition of this electrolytic deposition agent to a metal base or a base which is subjected to alumite treatment simplifies the printed- circuit board process of the metal base. Also, electrolytic deposition of this adhesive onto a conductor layer and its application onto an insulation base enables the printed- circuit board to be produced without using a solvent, thus simplifying the manufacture.

Filed: 1989-09-27
Abstract: PURPOSE:To decrease residual vibration and to expand a measurable range by applying the voltage in a reverse phase of the residual vibration which is generated in a high macromolecular piezoelectric film for a signal to a macromolecular piezoelectric film for control through a phase inverting circuit. CONSTITUTION:A switch A is closed, and a switch B is opened. Driving pulse are applied to a macromolecular piezoelectric film for a signal 1 from an oscillator 71. Then breathing motion is generated in the piezoelectric film 1 in the radial direction. The advancing direction of the generated ultrasonic wave is changed with a reflecting umbrella 4. A doughnut-shaped beam is formed and radiated. Even if the driving pulses are stopped, the residual vibration remains. When the driving pulses are stopped, the residual vibration remains. When a range to be measured is short, the reflected wave reaches when the residual vibration still remains. Therefore, separation and judgment of both waves become difficut. Therefore, the switch A is opened and the switches B and C are closed after the application of the driving pulses is finished. The residual vibration generated in the piezoelectric film 1 is amplified in an amplifier 72. A voltage in a reverse phase is applied to macromolecular piezolelectric film for control 61 through a phase invertor circuit 63. Thus the residual vibration can be decreased, and the measurement of a very short range and the measurement of an object having low reflectivity can be performed.
