IPC: B23K26/21
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for laser beam welding capable of simplifying preliminary preparation for welding and having little deformation owing to welding. SOLUTION: A carriage 11 equipped with a torch 14 to emit laser beam is made to travel on overlapped sheets (steel sheets 1, 2) along positions to be welded subjected to laser beam welding, and the overlapped sheets are made closely adhered by own gravity of this carriage 11 and then laser beam welding at the position to be welded is executed. By means of the method mentioned above, close adherance of the overlapped sheets is obtained by own gravity of the carriage 11; thus defective welding and deformation of the overlapped sheets are prevented, there comes no need of conventional tack welding, and then preliminary preparation for welding is simplified.

Title: Carrier for electrophotographic developer
Inventor: USHIYAMA NAOYUKI
IPC: G03G9/107
Filed: 1980-12-08
Abstract: PURPOSE:To provide a titled carrier of high abrasion resistance and a long life causing no sticking of toners on carrier surfaces by mixing elastomer having surface tension below specific values and magnetic powder, and granulating the mixture. CONSTITUTION:A soln. of elastomer of >=25dyne/cm surface tension selected from silicone elastomer, fluorosilicone elastomer, fluororubber, etc., and magnetic powder such as ferrite powder are mixed, and the mixture is granulated by a method such as spray drying, whereby the intended carrier for electrophotographic developer is obtained. The elastomer of >=24dyne/cm surface tension has the effect of peventing sticking of toners on carrier surface during long-time reiterative use, further absorbing the impact owing to the impingement of the carriers against each other and the impingement of the carriers and the toners, reducing the weight of the carriers per se, and reducing impingement energy. As a result, the abrasion, damage, etc. of the carrier surfaces are prevented.

Title: Crack detecting method for body surface
Inventor: KOSHIHARA TOSHIO
IPC: G01N21/88
Filed: 1988-07-11
Abstract: PURPOSE:To facilitate crack detection by bringing a thin film into contact with the surface of a body, and heating and photographing the surface by an infrared camera. CONSTITUTION:The thin film 3 is brought into contact with the surface of the body 1, heated by a heater 5 form the external surface side, and photographed by the infrared camera 4. The it is preferable that the thin film 3 cuts off infrared rays, attention is paid not to allow the thin film 3 to enter a crack 3, and heating is carried out abruptly in a short time. Then if there is the crack 2 in the surface of the body 1, it is found that there is air in the crack 2 by comparing the defect part with a sound part, so the heat conductivity of the defect part is small and the absorption of heat form the thin film 3 is small. Consequently, the defect part appears as a high-temperature part in an infrared image and the crack 2 can be detected.

Title: Composite logarithmic period antenna
Inventor: KURISHIMA FUMIYA
IPC: H01Q5/00
Filed: 1980-12-08
Abstract: PURPOSE:To make the size of antenna small and to widen the frequency band, by providing a compensation trap to a power feeding point of a linear antenna element. CONSTITUTION:A composite type antenna can be constituted by a 8-22 MHz logarithmic period antenna 3 and a linear antenna element fitted to the tip of the said antenna 3, e.g. cage type dipole antenna 4, extension coil 5, and arrester ground line 6 in common use with compensation trap. In this composite type antenna, when a cage type dipole antenna of 1/2 wavelength is assembled with the existing vertical type logarithmic antenna (V-LP) as it is, the ground height of a center feeding line of a V-LP antenna is in shortage. Thus, the cage type dipole antenna is loaded with an extension coil 5 at the voltage minimum point of the cage type antenna feeding, allowing to shorten the element real length. Thus, the assembling to the cage type dipole antenna V-LP can be made. The impedance matching of the cage type dipole antenna can be made by adjusting the distance (a) from the power feeding point 7 and the length (b) of compensation trap 7.

Title: Manufacture of semiconductor device
Inventor: GOSHIMA SHIGEO
IPC: H01L21/20
Filed: 1988-07-13
Abstract: PURPOSE:To lower contact resistance on a hetero-interface by selectively forming a graded layer in a specified region in the depth direction after crystal growth. CONSTITUTION:Undoped GaAs 2, undoped Al0.3Ga0.7As (20nm) 3, Si-doped Al0.3 Ga0.7As (21nm) 4 and Si-doped GaAs are epitaxial-grown successively onto a semi-insulating substrate 1 through an MBE method. An SiO2 film 7 is deposited onto a crystal surface through a CVD method, and annealed in an H2 air flow. 800 deg.C and fifteen min are used as the conditions of annealing. The disordered state is brought between the Si-doped Al0.3Ga0.7As 4 and the Si-doped GaAs 5 through annealing, and a graded layer 6 is shaped. Since the thickness of the graded layer 6 on a hetero-interface coincides with the diffusion length of Si, the film thickness of the Si-doped Al0.3Ga0.7As 4 is brought to 35nm and the film thickness of the undoped Al0.3Ga0.7As 3 to 6nm by Si diffused from the Si-doped Al0.3Ga0.7As 4 to the undoped Al0.3Ga0.7As 3. Each electrode of a source, a drain and a gate is formed through a normal method, thus shaping a field-effect transistor.

Abstract: PURPOSE:To secure an excellent display quality with a liquid crystal display device, by forming a light leading body by engaging the comblike 1st light leading body of such a shape that its leading edge side is gradually made thinner and plural teeth are protruded from the base section, with the 2nd light leading body having the same shape as the 1st body has and providing one kind of light source to each light leading body. CONSTITUTION:When a red lamp 14 is turned on, its light is diffused by a diffusing plate 11 and projected on an LCD 10 after it is reflected by the curved surface 12c of the 1st light leading body 12. Since the leading edge side of the teeth section 12a of the body 12 is gradually made thinner, the difference between the darkness and lightness of the red-colored light projected on the LCD 10 can be made smaller, namely, the light can be made uniform and, as a result, an excellent display quality can be secured, when the pitches of the plural teeth sections 12a are appropriately made finer. When a blue lamp 15 is turned on, the light of the lamp 15 is projected on the LCD 10 after it is reflected by the curved surface 13c of the 2nd light leading body 13. Similarly, uniform blue light can be projected on the LCD 10, when the pitches of the teeth section 13 is appropriately made finer.

Filed: 1994-06-30
Abstract: PURPOSE:To prevent the deterioration of an S/N ratio due to excessive erasure by forming a pilot signal for tracking using an erasing head having a track width of the sum of the track widths of plural recording heads. CONSTITUTION:By performing inserting recording by means of recording heads HAX and HBX after an erasing head HE1X erases recording tracks TRA and TRB already recorded in the state of tracking by the erasing head HE1X for a recorded pilot signal PL, the inserted recording tracks TRAX and TRBX are formed by performing inserted recording by means of the recording heads HAX and HBX.
