Patent JP-H03220708-A (JP)
Title: Electronic component
Inventor: NISHIZAWA HIDEO
IPC: H05K3/34
Filed: 1990-01-25
Abstract: PURPOSE:To prevent a decrease in a solder wettability by covering a part to be solder connected of an exposed part of a lead frame with an oxidation preventive layer instead of a solder plating. CONSTITUTION:Electric contacts 2 of a switch are formed on the upper surface of a lead frame 1 made of copper at the inner end. The contacts 2 are formed by boding noble metal chip of silver or the like to the frame 1. In its manufacturing method, the frame 1 is first charged in a mold. Then, resin is poured in the mold to be molded. Thereafter, the exposed part 1a of the frame 1 is coated with flux. Thus, since the part 1a of the frame 1 is covered with an oxidation preventive film 5 made of flux, the frame 1 is not oxidized even if a long period is elapsed. Thus, a decrease in the solder wettability of the frame 1 can be prevented, and an electric component can be effectively soldered to a board.

Filed: 1985-02-01
Abstract: PURPOSE:To enable to undersore in a color different from the color of characters, by a method wherein one or more of a plurality of recording means is set to record in a color different from the recording color of the other recording means, and a predetermined emphasis record pattern is formed by the recording means set for the different color. CONSTITUTION:While following a program stored in a ROM3, a CPU2 controllingly drives a recording head 8, a motor 9 and a motor 10 through drivers 5, 6, 7 in accordance with recording data transferred from a host computer 1. The recording head 8 comprises 9 ink jet nozzles DT1 arranged in a vertical row, and comprises heating resistors for each of the nozzles. When an electric current is passed to the resistor, an ink in the corresponding nozzle is instantaneously boiled, and an ink is jetted from a jet port, whereby a record dot is formed at a position corresponding to the nozzle. By setting the recording color for the nozzle DT9 to be different from that for the nozzles DT1-DT7, a character can be underscored with a higher degree of emphasis.

IPC: G01N21/94
Filed: 1988-01-29
Abstract: PURPOSE:To enable accurate detection of a foreign matter, by irradiating a substrate with a laser light simultaneously both on the top and the undersurface thereof. CONSTITUTION:A laser light 7 from a laser light source 6 is divided with a half mirror 9 and a part (the other via symmetry-side optical paths) thereof is transmitted through a total reflection mirror 10a and 10b, galvanomirror 8a, Ftheta lens 2a and a pellicle 11a to form a beam spot on a substrate (reticule) 1. Then, the laser light 7 is divided in two to irradiate the substrate 1 obliquely on the top and undersurface thereof 1 simultaneously. With such an arrangement, secondary lights 4 and 4' emitted from a circuit pattern 12 are detected as large signal with detectors 5a and 5c on the top and undersurface of the substrate. On the other hand, while scattered lights 4a and 4a' from a foreign matter 13 adhering to the surface of the substrate 1 are caught as signal with the detector 5a on the side of the adhesion surface, with the detector 5c on the back thereof, the scattered light 4a' is attenuated by the substrate 1 to give a small signal of about noise level. Thus, a pattern 12 (or the foreign matter 13) is determined when a signal exceeding a normal value is detected with both the detectors (or either thereof).

Title: Wall pannel mounting structure
Inventor: SHIBATA MASUHIRO
IPC: E04B2/56
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To dispense with boring work for a wall pannel, enhance mounting workability and respond to swinging to the in-plane direction with flexibility by fastening the wall pannel to a reinforcing member by a tapping screw screwed in a butt end of the wall pannel. SOLUTION: Horizontal frame members 6a, 6b are fixed between vertical reinforcing frame members 5a, 5b, and wall pannels 8a, 8b are fitted to the circumference of an opening 7 surrounded by the members 5a, 5b, 6a, 6b. A support plate 9 is welded to an upper surface of the member 6a, then a tapping screw 11 is screwed through an insertion hole 10 in the plate 9 from a butt end surface of the pannel 8a, and it is fastened. Thus, there is no need for preliminarily forming the insertion hole of screw in the pannel 8a, which facilitates the mounting work. Since the screw 11 itself is separated with respect to the member 6a, when an excessive force such as shearing stress to the in- plance direction of the pannel 8a is applied, the screw 11 is displaced to incline to the member 6a to thereby release the excessive moment or force for reducing the stress acting on the pannel 8a.

Title: Agc circuit
Inventor: SASAKI KAZUTOSHI
IPC: H04B1/16
Filed: 1983-02-04
Abstract: PURPOSE:To prevent the generation of distortion and to make the operation stable by performing AGC of a variable gain amplifier with multi-stage constitution. CONSTITUTION:A resistor R1 is inserted into the variable gain amplifier VCA to control the changing range of an attenuator (ATT). When a DC control voltage Vc is smaller than the reference voltage V, a transistor (Tr) Tr1 is off, the AGC is quite the same and the gain becomes output Vo/input Vi=(R1+ R2)/R3. When a Tr Tr2 is completely turned off in Vc>V, AGC is maximized and the gain is Vo/Vi=R1/R3. At the time of normal operation, the gain is changed between both the Trs, so that the ATT limit of each VCA can be controlled individually. Therefore, stable operation freed of distortion can be attained.

Title: Pipe-like frp molding and its manufacture
Inventor: MORI SADAKI
IPC: B29K105/08
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To scarcely release a paint or marking material without lowering a strength by forming a filling recess recessed inward on an outer periphery of an FRP body obtained by laminating prepregs in a cylindrical state and curing it, and filling the paint or the material in the recess. SOLUTION: The pipe-like FRP molding 1 is formed with a filling recess 20 recessed radially inward on an outer periphery of an FRP body 12. The body 12 is formed substantially uniformly in its thickness. A paint 21 fills the recess 20 so that the periphery of the molding 1 becomes a flattened state without protrusion and recess. Thus, since the paint 21 is filled in the recess 20, even if a coated film is thickened, a surface of the paint 21 becomes substantially in plane with the surface of the body 12, and hence there is less fear of bringing about a damage according to a using state or a release due to a use for a long period. Since polishing is of the degree of cutting off a release material, there is no fear of lowering its strength.
