Title: Speaker
Inventor: MAEDA KEIJIROU
IPC: H04R9/06
Filed: 1979-01-16
Abstract: PURPOSE:To make it possible to cope sufficiently with strong rotational vibrations relatively-high in frequency by constituting a coupling body, connected to a diaphragm, by a hollow body and then by reinforcing this coupling body by a reinforcing method. CONSTITUTION:On the back surface of diaphragm 11, coupling body 29 is bonded perpendicularly at its center position P1. Free end part 29a of this coupling body 29 is supported by supporting method 31, e.g. damper 32. Then, distance l2 between free end part 29a and diaphragm 11 is set much longer than distance l1 between damper 15 supporting voice coil bobbin 13 and diaphragm 11. As a result, rotational vibrations of diaphragm 11 in the direction of arrow (a) or (b) are converted into those of coupling body 29 in the direction of arrow (c) to prevent rotational vibrations of rotary disk 11 securely. Further, coupling body 29 is composed of a hollow body and reinforced by a reinforcing body to improve rigidity against inflection and torsion. In consequence, coupling body 29 can be vibrated following accurately up diaphragm 11 and it is made possible to cope sufficiently with rotational vibrations high in frequency.

The fluid flows through an inlet pipe into a body 3 where the solid in the fluid is deflected due to enlargement of the fluid passage therefor so that solid is diffused into the gas to be uniformely distributed. Thus the biphase fluid of solid and fluid in which the solid is uniformly distributed is discharged from the body 3 into an outlet pipe 7. Accordingly, the fluid having the uniform distribution of concentration of solid in the cross-sectioned area of the fluid passage of the outlet pipe 7 flows therethrough so that a flowmeter of, for example, correlation type connected to a pipe line which is connected to the outlet pipe 7 or the flange 7a, may precisely measure the flow rate of solid even if the solid flows into the body 3 from the inlet pipe 1 in its deflected condition.

Filed: 1985-01-14
Abstract: PURPOSE:To improve the uniformity of etching by making a quantity of spout of a halogen compound spouted from a circumference of a gas spout electrode less than that of the central part. CONSTITUTION:A quantity of spout of a halogen compound is previously calculated from analysis of a gas flow in the device and that of concentration of the reactive molecules. The halogen compound gas is led to an opening of the upper electrode 2 through valves 14 and 15, and an inside guide path 12 and an outside guide path 13 in a tube 11. The gas passing the inside path 12 flows in the inside flow path formed by a partition panel 10 and passes a dispersion plate 7 inside of the flow.

The gas passing the outside path 13 passes the outside flow path formed by the partition panel 10 and through the dispersion plates 8 and 9, it spouts on the circumference of the wafer 6. In this constitution, there are two courses for introducing the gas spouting on the wafer so that the quantity of spout on the center and circumference of the wafer can be preset separately and the etching rate can be made uniform on the surface.

Title: Optical recording medium and production thereof
Inventor: SAITO KOICHI
IPC: G11B7/243
Filed: 1988-01-11
Abstract: PURPOSE:To improve bit error rate(BER) while maintaining stability of recording and reproduction characteristics, by specifying the electric resistivity of a thin platinum film. CONSTITUTION:The electric resistivity of a thin platinum film provided on a transparent resin substrate must be not more than 3.0X10<-5>OMEGA.cm. If the resistivity is higher than the range, BER becomes higher, which is undesirable. The thin platinum film with the resistivity and stability can be obtained by, for example, an ion plating method in which a platinum passed through a gas activated to a plasma state is deposited on the resin substrate. The thickness of the thin platinum film is 50-300Angstrom , preferably 80-200Angstrom . If the thin film is thinner than said range, the film is low in strength, whereas if the film is thicker than said range, the laser power required for recording is too high that the product is poor in suitability to practical use.

Title: Mold device
Inventor: FUSE HIROKI

Filed: 1988-01-12
Abstract: PURPOSE:To prevent a sheet from being shifted in the flowing process of resin, while the necessity for drilling the sheet is omitted by a method in which the space for molding a boss part is formed by a sleeve pin, a core pin and a core, and the is formed so that the sheet is pushed against the tip part of the core pin and is broken by the molding pressure of the resin flowed into the space. CONSTITUTION:A sheet 17 is placed on a core 11, and the sheet 17 is pinched in between the core 11 and a cavity 12 by covering the core from upper side with the cavity 12. In this state, the inside of the space 13 between the core 11 and the cavity 12 is filled with resin 18. When the resin 18 reaches the sheet 17 above the space 16 for molding a boss part, the sheet 17 is bent to the space 16 by the pressure of resin molding. Consequently, the sheet 17 is brought in contact with the sharpened tip part 15a of a core pin 15, and is broken. With the increase of the packed resin, the breakage of the sheet 17 becomes large gradually, and the sheet is pushed against the wall surface of the space 16. While the resin 18 pushes the sheet 17 against the wall surface of the space 16, the resin flows into the inside of the space 16, and the space 16 is filled. Thus, the molded objected provided with the boss part and the sheet integrally molded, is obtained.
