Title: Speaker system
Inventor: HONDA KAZUKI
IPC: H04R1/02
Filed: 1987-09-08
Abstract: PURPOSE:To improve radiation efficiency at low frequency range and to flatten the sound pressure characteristic of middle and high frequency range by composing an acoustic tube on the back face of a speaker unit and providing in the acoustic tube at least one hollow space having a cross-sectional area larger than the cross-sectional area of the acoustic tube. CONSTITUTION:A cabinet 5 to constitute the acoustic tube which is extended continuously from the speaker unit back surface and whose opening 8 is opened to a sound field and at least one hollow space 6 having the cross-sectional area larger than the cross-sectional area of the acoustic tube 5 are provided in the acoustic tube 5. That is to say, the sounds of the middle and high frequency range from the speaker unit back face to pass through the acoustic tube and to be radiated to the sound field is acoustically interrupted by a reactance component presented by acoustic compliance in the hollow space 6 and the hollow space 6 operates as an acoustic filter to interrupt the high frequency range. Thus, the sound pressure level of only the middle and high frequency range is widely decreased, interference between them and middle and high tones to be radiated from a speaker unit front face is eliminated and a speaker system without the nonuniformity of the sound pressure characteristic of the middle and high tones and without sound degradation can be obtained.

Abstract: PURPOSE:To prevent the breeding of dislocation, and improve the mechanical strength of a semiconductor wafer, by implanting impurity not participating in electric characteristics, into the surface region of a substrate after thermal treatment, and the etching region after etching process. CONSTITUTION:After an SiO2 film 20 is formed, resist 21 is spread thereon, and boron is selectively implanted. Then the resist 21 is eliminated, and the implanted boron is diffused by a thermal treatment to form a well region 22. Oxygen or nitrogen is ion-implanted to an amount which does not participate in electric characteristics. After an SiO2 film 23 is deposited on a film 20 and a groove 24 is formed by etching, an SiO2 film 25 is formed in an dry-oxygen atmosphere. After that, applying the film 23 to a mask, oxygen or nitrogen is ion-implanted in the bottom of the groove 24 to an amount which does not participate in electric characteristics. An SiO2 film 26 is formed.

Title: Method for plating electric contact
Inventor: SATOU TAKEHIKO
IPC: C25D7/00
Filed: 1982-12-21
Abstract: PURPOSE:To reduce the cost of an electric contact obtd. by subjecting a copper alloy substrate to nickel plating, gold striking and gold or silver plating without deteriorating the adhesive strength by carrying out palladium striking in place of the gold striking. CONSTITUTION:A copper alloy substrate for a contact maker is plated with nickel to increase the hardness and to prevent the diffusion of the copper alloy. In order to improve the adhesive strength, a palladium layer is electrolytically deposited, an oxide film is removed, and fine palladium particles are uniformly deposited to form a striked layer. Gold or silver plating is then carried out to prevent the increase of the contact resistance. The cost is reduced by forming the striked layer using palladium in place of conventional gold.

Abstract: PROBLEM TO BE SOLVED: To prevent the uneven wear of a rack shaft and of a pinion shaft by containing a linear ball bearing consisting of a pair of guide members, which are arranged on both sides of a cylindrical member and on the internal surface of which a guide groove is formed to connect a first linear groove, a second linear groove and a ball returning hole. SOLUTION: When torque is converted into linear advancing force in a ball screw mechanism 70, the torque acts on a rack shaft 25. The rotation of the rack shaft 25, however, is prevented by a linear ball bearing 100. In other words, as the rack shaft 25, or a ball screw shaft 27, advances, a ball 108 also advances to the space between a linear groove 91 of a cylindrical member 94 and a linear groove 106 of the ball screw shaft 27, the ball 108 is guided outward in the radial direction by means of a guide groove 96 of a forward guiding member 98, is returned backward from a returning hole of the guiding member 94, and the ball 108 is guided inward in the radial direction by means of a guiding groove 96 of an afterward guiding member 98 in order to return to the space between the linear grooves 91 and 106. Owing to the circulation of a large number of balls 108, the advancing of the rack shaft 25 is allowed.
