Title: High-frequency electronic device
Inventor: ONOUCHI YOSHIO
IPC: H05K9/00
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To lessen a height of fitting to a motherboard and to attain simplification of a fitting operation by a method wherein legs for fitting to the motherboard are provided at about the central position of the height of two opposite side plates of a shield case having a plurality of side plates. SOLUTION: In a state wherein a high-frequency electronic device is fitted to a motherboard 25, the fitting height thereof from the motherboard 25 is about half of a fitting height in a usual fitted state, when the plate thicknesses of an upper cover 2 and a lower cover 28 and others are neglected. Besides, terminals 27 are fitted at positions at about the same height as fitting legs 24 and, therefore, they are set on the motherboard 25 only by inserting the fore end parts 26 of the fitting legs 24 through holes 9 of the motherboard 25. Since the terminals 27 are soldered, as they are, to a conductor pattern 12 on the motherboard 25, accordingly, an operation of fitting to the motherboard 25 is made simple. Besides, the terminals 27 can be shortened without necessitating bending and so they are bent little, which facilitates the fitting operation further.

Title: Production equipment of foam thermoplastic resin sheet
Inventor: KITAYAMA TAKEO
IPC: B29C48/305
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To realize a miniaturized production equipment by a method wherein at least a part of a wall part surrounding a vacuum chamber is made of a member having a plurality of vacuum vents so as to execute evacuation through this member. SOLUTION: The inner wall parts 14 of a movable upper wall part 12 and of a movable lower wall part 13 are made of members having evacuation vents such as porous electroformed shells. When a foaming agent and a thermoplastic resin are melted and kneaded in an extruder 1 and extruded through a die 3 in the form of a sheet-like expandable thermoplastic resinous body 6a, the distance between the wall surface 12a of the movable upper wall part 12 and the wall surface 13a of the movable lower wall part 13 is made narrower when the evacuation of a vacuum chamber is not yet started, and consequently the thickness of the resinous body 6a is thin, while the distance is made broader when its thickness becomes thick after the start of evacuation of the chamber and the expansion of the resinous body,  resulting in preventing the situations such as the scratching of the surface of a sheet 6 and the crushing of bubbles from occurring. The edge parts of sealing materials 31 reach the surfaces of the resinous body 6a so as to cover the outlet of the vacuum chamber, resulting in evacuating the vacuum chamber 4 for expanding the resinous body and making the distance between the wall surfaces 12a and 13a broader until the desired thickness W2 of the resinous body is obtained. By passing through an expanding zone 7, the resinous body 6a expands more so as to obtain a foam thermoplastic resin sheet 6.

Title: Rolling guide mechanism and its positioning method and device
Inventor: FUTAMI SHIGERU
IPC: F16C29/04
Filed: 1991-12-27
Abstract: PURPOSE:To shorten the setting time of positioning by controlling the pressure applied to rolling bodies from outside to vary the motion of the rolling bodies depending on whether a moving member is moved or stopped. CONSTITUTION:A stationary member 2, a moving member 1, and rolling bodies 3 are made of a ferromagnetic material. The magnetic force acting between the stationary member 2 and the moving member 1 acts as a direct current magnetic force when the moving member 1 is stopped or positioned. Immediately before the moving member starts to move, the magnetic force acts as an alternating current magnetic force whose amplitude is decreased for the purpose of demagnetization, and when the moving member is moved, no magnetic force is applied.

Title: Cover material for light projection such as lighting apparatus
Inventor: YAGI TOSHIYUKI
IPC: G09F13/08
Filed: 1991-12-27
Abstract: PURPOSE:To maintain both total ray transmittance and haze value at a high level by scattering transparent bead layers varying in refractive index from a base layer consisting of a transparent synthetic resin into the base layer. CONSTITUTION:The cover material A is constituted by scattering the beads 2 of a transparent acrylic polymer varying in the refractive index from the base layer 1 consisting of a polyvinyl chloride resin which is the transparent synthetic resin into the base layer 1. The greater part of the rays emitted from a light source transmit the base layer 1 while repeating refraction and reflection when the rays enter the base layer 1 when the rays enter the beads 2 and emerge therefrom or when the rays emerge from the base layer 1 and, therefore, the light scattering characteristic is enhanced if such cover material A is used for the lighting apparatus using a fluorescent lamp as the light source. Consequently, the real image of the light source is hardly visible through the base layer 1. The base layer 1 and the beads 2 are both transparent and, therefore, the rays are hardly shut off by the base layer 1 and the beads 2. Then, the transmittance of the collimated beams of light is lowered and the haze value is increased with respect to an increase in the total ray transmittance and the light diffusion rate.

Abstract: PURPOSE:To copy an original in a state where it turns upward, to protect eyes and to easily turn over the pages of the original by hand by providing an optically transmissive plate for transmitting a copied image and an original platen. CONSTITUTION:In the case a heavy book is placed on the original platen 2, the original platen 2 is moved by a spring 3 in parallel with a screw 5 for guiding a spring and the levels of right and left copying surfaces always become equal to each other even though the numbers of right and left pages are different. The spring 3 has a spring constant obtained by dividing an amount obtained by multiplying the average specific gravity of paper by area, thickness and gravitational acceleration by the thickness. In the case when the mass of the paper is extremely different, it is adjusted by a fastener 4.

Title: Semiconductor device and its manufacture
Inventor: TOKUSHIGE TOSHIMICHI
IPC: H01L21/60
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To improve reliability by forming an Si3N4 film on an interface between a wiring whose main material is Cu and polyimide resin covering the wiring, preventing reaction of imide resin before curing with Cu, and covering a metal post and side surfaces of a thin film layer of Cu with Si3N4. SOLUTION: A photoresist PR2 is formed from which a wiring layer 7 corresponding to a region, on which a metal post is to be formed, is exposed, and a metal post 8 of Cu is formed on the exposed part by electrolytic plating. Since Cu 8, Ni 10 and Au 11 are continuously formed without leaving them for a long time, and oxidation of Cu and Ni can be prevented. After the photoresist PR2 is eliminated and a thin film layer 6 of Cu is eliminated by using the wiring layer 7 as a mask, an Si3N4 film SN is stuck on the whole surface containing the wiring layer 7 and the metal post 8 by a plasma CVD method. Since polyimide resin to be formed in a later process is active and reacts with Cu, the wiring layer 7 and the metal post 8 are wholly covered with the Si3N4 film.

Title: Come-off structure of inner rear view mirror
Inventor: IWAMA SATOSHI
IPC: B60R1/04
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To provide come-off structure of an inner rear view mirror which infallibly comes off when substantially a constant external force is applied, regardless of a direction to which external force is applied. SOLUTION: A supporting member 7 is fixed to a connecting surface of a stay 2 to base. A circular spring 8 is secured to a hook portion of the supporting member 7. A peripheral portion of the circular spring 8 is secured to an inner surface of a lip face 6 formed on the base. The inner surface of the lip face 6 is formed in conical face, and thereby a stay 2 comes off the base with substantially constant force, regardless of a direction of an external force applied to the mirror body. Consequently, when the impact is applied from the outside, the mirror body and stay 2 can come off infallibly at a point where the predetermined force is applied.
