Title: Method and equipment for inspecting lead of semiconductor package
Inventor: UMADONO SHINJI
IPC: G01B11/24
Filed: 1993-03-04
Abstract: PURPOSE:To measure and inspect the floating, width, and pitch of the leads of a semiconductor package accurately and sufficiently even if the leads are arranged at a fine pitch without causing any trouble in mountability in following processes. CONSTITUTION:The extending region of each lead 21a is irradiated with laser light and the height and position in the pitching direction of the lead 21a are detected based on the variation of reflected laser light when the irradiating position is moved relatively in the pitching direction of the lead 1a The floating, pitch, width, etc., of the lead 21a are then determined based on these data and compared with predetermined reference values thus inspecting the lead. In such an inspection method, The quantity of reflected light is measured and the variation thereof is compared with a coordinate signal representative of the irradiating position thus detecting the position of the lead 21a in the pitching direction.

Title: Formation of beam spot of optical pickup
Inventor: KAWAOMO HISASHI
IPC: G11B7/135
Filed: 1990-03-17
Abstract: PURPOSE:To reduce the converging spot diameter of a light beam and to simultaneously decrease the loss of a light quantity by expanding the diameter of the light beam simultaneously with alternation of the inner peripheral side and outer peripheral side of the light beam on the side where the diameter of the light beam is narrow. CONSTITUTION:The light beam 10 emitted from a semiconductor laser 1 is collimated to collimated light beams by a collimator lens 2. Of the collimated light beams, the light beam 12 on the narrower side is inverted in the inner and outer peripheral parts by a hexagonal cylindrical prism 7. The disk 5 is irradiated with a beam spot P thereupon after the beam passes an objective lens 4. The beam width on the narrow side is controlled if the size in the optical axis direction of this prism 7 is properly selected. Namely, the spot diameter of the light beam is reduced in the state in which there is substantially no loss of the light quantity.

Title: Liquid fuel combustion device
Inventor: YOSHINO KEIZOU
IPC: F23D3/40
Filed: 1978-06-07
Abstract: PURPOSE: To mix supplied air effectively with the fuel steam to stabilize the combustion by making the air holes in the evaporation chamber side wall so that they face the rectifying plate mounted on the inner side wall of the evaporation chamber.  
     CONSTITUTION: The lower part air holes 4 are made at the positions in the evaporation chamber that they face the evaporating part 2, and the upper air holes 5 are made at the positions that they face the rectifying plate 6. The rectifying plat 6 is glued on the side wall of the evaporrating chamber 3 at an acute angle α to form the small chamber of which cross section makes a triangle. By so constituting, the evaporated fuel from the evaporating part 2 is conveyed by the air (a) supplied through the lower air holes 4 and diffused in the evaporating chamber 3, but since the amount of air is very small, it does not form flames. The mixed gas with excessive fuel becomes gas flow (b) when it goes up, and it is efficiently mixed with air (a') supplied through the upper air holes 5 by the influence of the rectifying plate 6 to be mixed gas (c) and produces stable small flames (d).

Title: Window glass subjected to partial water repellent treatment
Inventor: KUMAZAWA MASAYOSHI
IPC: B60S1/02
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide window glass subjected to partial water repellent treatment allowing certain removal of adherent snow without degradation in a visual field or bad influence on glass, and allowing low-cost application. SOLUTION: Water-repellent coating films 1, 1a are applied to a lower end part and/or a side part of a windshield 2 of a vehicle cab 3. Thereby, snow wiped by wipers 4 from a surface of the windshield 2 to the lower part and/or the side part is repelled by the water-repellent coating films 1, 1a and falls downward without remaining in the lower end part and/or the side part, so that the snow removal can be certainly executed. Because the water-repellent coating films 1, 1a are applied only to the lower end part and/or the side part of the windshield 2, degradation of a field view or bad influence on the wipers 4 is hardly caused.
