Title: Float for carburetor
Inventor: HARA HIROYUKI
IPC: F02M5/16
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To enlarge buoyancy without increasing volume by coating the surface of a float with low surface energy material mainly composed of fluoroalkylsilane. SOLUTION: First, the surface of a float 7 is degreased with a solvent such as ethanol or the like and washed. Secondly, a coating liquid mainly composed of fluoroalkylsilane(FAS) is put in a dipping vessel to make the coating liquid adhere to the whole surface of the float 7. By using an air blow device or a centrifugal separator, coating liquid adhering to the surface of the float to excess is removed. Then, the float is put in a drying chamber for volatilizing a solvent in the adhering coating liquid to be dried. After that, the float 7 is put in an electric furnace and burnt below a heat resisting temperature. By the above steps, a fluoroalkylsilane coat film 14 is obtained on the surface of the float 7. Accordingly, a float of the same volume can be applied to an internal combustion engine having a larger displacement, and the accuracy of oil surface can be improved.

Title: Position detecting sensor for fillet welding line
Inventor: FUKUI KIYOUJI
IPC: G01B11/00
Filed: 1981-08-28
Abstract: PURPOSE:To obtain a compact and accurate sensor by providing a position detecting sensor for filler welding line with one projecting axis and two photosensitive means. CONSTITUTION:A welder fitted on the leading end of a torch T is positioned on a fillet welding line for two members W1, W2 which are intersected at right angles. The member W1 is irradiated with laser light from a laser source 1 through a modulator 3 and an optical fiber 3. The optical fibers 3, 5, 6 are paralleled at the inside of a member 4 and, when it is defined that the center line between the fibers 5 and 6 is C1 and the center line between the C1 and the fiber 3 is C2, the leading end of the welder is arranged on the C2. A position in the X direction is controlled so that the C2 is inclined to the W1 by 45 deg. and the reflected optical axis B1 from the W2 is made coincident with the C1, i.e. the quantity of light detected by the fibers 5, 6 are made equal. The distance between the WL and each member is defined by constantly fixing the strength of  reflected light. The Y direction is also controlled by using the optical fibers arranged on the positions obtained by rotating the fibers 5, 6 around the C1 by 90 deg..

Title: Driving device for roller leveller
Inventor: MATSUO HIROSHI
IPC: B21D1/05
Filed: 1981-08-29
Abstract: PURPOSE:To prevent a driving system from the generation of torque due to a circulating power, by installing a sun and planetary gear mechainism between a group of pinion gears, rotating work rolls reversely to each other, and a driving motor, and providing a restricting means of maximum torque to a sun gear of the mechanism. CONSTITUTION:For instance, when the 1st group of groups of pinion gears 9a- 9d, 9e-9h and 9i-9k is smaller in diameter than the other groups, the generation of torque due to a power circulation is prevented by increasing the rotating angle of the group of rolls of small diam. This purpose is achieved by clockwise rotating a sun gear of a sun and planetary gear mechanism placed between a driving motor 1 and gear groups 9 by the action of hydraulic cylinders 17a and 17b which hold an arm 16. Then the cylinders 17a and 17b are controlled so as to return the arm 16 to the original position after a passing through of a material to be rolled.

IPC: H04N1/04
Filed: 1982-08-03
Abstract: PURPOSE:To always secure high reading performance, by detecting the deterioration of a fluorescent lamp and to inform the time of replacement of the fluorescent lamp. CONSTITUTION:A picture signal delivered from an image sensor 6 is amplified up to a prescribed level by an amplifier 7 and applied to a peak holding circuit 8 as well as to a shading distortion compensating circuit 9. The picture signal compensated by the circuit 9 is converted into a signal of a binary level by a binary coding circuit 10 and transmitted. Both picture signal and output of the circuit 8 are supplied to a shading distortion level detecting circuit 11. An output signal is generated when the shading distortion exceeds a prescribed level to drive an informing circuit 12. When a fluorescent lamp is deteriorated, the shading distortion increases. Therefore it is possible to understand the deteriorating state of the fluorescent lamp by the circuit 12.

Title: Tab film for preventing thermal deformation of leads
Inventor: NAGASHIMA HIDEAKI
IPC: H01L21/60
Filed: 1993-06-08
Abstract: PURPOSE:To prevent fatigue breakdown of an input signal lead which is to be caused by bending deformation, by forming notches in a TAB film, and reducing shearing rigidity of the TAB film.

Notches 6a are formed in the TAB film 3, and shearing rigidity is reduced. Thereby the shearing deformation of the TAB film 3 is absorbed, so that the bending deformation of input signal leads 5 is reduced. Hence the fatigue breakdown of the input signal leads which is to be caused by bending deformation can be prevented.

Abstract: PURPOSE: To distribute grinding allowance with high accuracy and automatically by allowing a gear to perform the rotation related to indexing and relative traverse of the gear in time, by means of numerical control by a computer. CONSTITUTION: A probe having a spherical tip B is positioned in a space between tooth flanks on both sides of a tooth space G to rotate a gear in one direction until one tooth flank Fa activates the probe, and the angular position (Oa deg.) of the gear at the moment is recorded in a computer. Next, the direction of rotation of the gear is reversed, the gear continues the rotation until the adjacent tooth flank Fb activates the probe, and the angular position (Ob deg.) of the gear at the moment is recorded in the computer. The difference between the two rotational positions, namely Oa deg.-Ob deg. is calculated, and the gear is driven in opposite direction under computer control by the length of an arc equal to the half of the value calculated.  At this time, the center of the spherical tip part B, and therefore a grinding wheel are aligned with the tooth space G, and thus grinding allowance is precisely distributed.
