Title: Electronic component mounting method and electronic component mounter employing the method
Inventor: OKADA YASUHIRO
IPC: H05K13/04
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To check the accuracy of a component feeder before and during production by calculating the difference of the electronic component position calculated from the mark position of a component feeder from a design value, the difference of positional relationship among a plurality of marks and the difference of the mark positions themselves and then comparing the results with specified threshold values. SOLUTION: Using the recognition positions of marks B, C, D and E, component position calculation values X, Y of the marks C, E, for example, are calculated from the position of the marks B, D. Subsequently, the difference of the calculation values from, the design values x, y of the component position are calculated ΔX=X-x, ΔY=Y-y along with the difference of the marks themselves. These differences are then compared with a specified threshold value and if the value determined according to an expression ΔX<2> /0.1<2> +ΔY<2> /0.05<2> is 1 or above, a decision is made that the accuracy of a cassette is bad and a compound feeder requires maintenance before the operation thereof is interrupted otherwise correction and control of the difference are designated.  According to the method, failure can be suppressed without using a component feeder having bad accuracy while correcting the shifted allowable range.

Title: Changeover device for urinal member and seat member for stool
Inventor: IWAHASHI MASAO
IPC: A47K13/08
Filed: 1986-05-19
Abstract: PURPOSE:To make it easy for a passenger to evacuate or urinate by mounting a seat member for both women and men and a urinal member for only men at the front and rear sides of a swingingly operated member, respectively, and enabling the seat and urinal members to be selectively changed over. CONSTITUTION:At the time of woman's need and man's need, a seat member is placed on a stool member 4. On the other hand, at man's need for only urinating, a urinal member 7 for men is placed on the stool member 4 in such a way that a swinging shaft 9 is turned substantially 90 by driving a motor 15, and a swing plate 8 thus swings on the upper side of the stool member 10. As the upper peripheral part of the urinal member 7 is set high, it is therefore easy for a man to urinate without sputtering his water around the urinal member 7 even if his body oscillates due to vehicular oscillations.

Title: Schottky-junction-type field effect transistor
Inventor: KAKUWA HARUO
IPC: H01L29/78
Filed: 1985-05-31
Abstract: PURPOSE:To improve the surge characteristics, by forming a Schottky junction in a part of a source electrode oposed to a gate feeding point. CONSTITUTION:A Schottky junction 11 is formed in a portion on the periphery of a source electrode 104s adjacent to the feeding center 114g for a gate electrode 104g. If the Schottky metal layer is formed to cover all over the surface of the electrode 104s opposed to the electrode 104g, the resistance between the gate and source electrodes will be increased, causing the deterioration of the high-frequency characteristics. In contrast, the Schottky junction 11 formed partially as described above can allow the electric current tending to concentrate to the ends of the source electrode to be distributed from the surface of the wafer to the inside thereof, and therefore the resistance to electrostatic breakdown can be improved.

Title: Hydraulic control device for automatic transmission
Inventor: OOTSUKA KUNIO
IPC: F16H61/08
Filed: 1982-07-07
Abstract: PURPOSE:To prevent the shock of an automatic transmission by increasing the operating pressure of a band brake and to reduce the operating pressure of a clutch when the transmission is set to a reduction gear position using an engine brake. CONSTITUTION:When a manual valve is set to a reduction gear position using an engine brake, a line pressure increases since a pressure modifying valve acts the highest hydraulic pressure to a line pressure regulating valve. Since the increased line pressure acts as the operating pressure of a brake, the capacity of the brake increases. On the other hand, the hydraulic pressure which is decreased lower than the line pressure is produced in the port 921c of a 2-speed fixing range pressure reducing valve 918. The reduced 2-speed fixing range pressure is led to the port 926d of a 2-speed fixing range switching valve 917, and supplied from the port 926c through an oil passage 931 to a clutch.
