Title: Manufacture of wiring board
Inventor: MORI MITSUMASA
IPC: H05K3/24
Filed: 1989-08-29
Abstract: PURPOSE:To restrain the degeneration of a polyimide precursor on a copper conductor wiring and the generation of a residual film at the time of patterning by forming an insulating layer on the copper conductor wiring after subjecting the copper conductor wiring to the surface change in quality which restrains the movement of electrons through the surface. CONSTITUTION:After a copper conductor wiring 2 is formed on a ceramic substrate 1, palladium ions 5 are adsorbed on the surface of the copper conductor wiring 2. For example, the substrate is immersed in a mixed solution of palladium chloride and hydrochloric acid for about 5 minutes. After that, a polymide precursor film 4 is formed on a wiring substrate and patterning is done on the copper conductor wiring 2. At this time, as palladium ions 5 adsorbed on the surface of the copper conductor wiring 2 have an electron catching action, the movement of electrons between the copper and the polyimide precursor is restrained considerably. Accordingly, a remarkable chemical mutual action does not take place and degeneration of the polyimide precursor film 4 on the copper conductor wiring 2 and generation of a residual film at the time of patterning don't occur.

Title: Zoom lens
Inventor: KITAGISHI NOZOMI
IPC: G02B15/173
Filed: 1983-11-25
Abstract: PURPOSE:To attain balanced compensation with various abberations by dividing the IV lens group into the pre-group having positive power and the post-group having negative power and satisfying the converging surface of the pre-group of which projected side is turned to the object side and a diverging surface of the post-group of which recessed surface is turned to the objective side with specific conditions. CONSTITUTION:Formulas (i) and (ii) show the available ranges of the refractive powers psiA, psiB of the converging surface A of the pre-group of the IV lens group and the diverging surface B of the post-group and formulas (iii), (iv) show conditions for allowing the surfaces A, B to cancel spherical aberration and then cancel coma and astigmatism each other. If the refractive indexes of the pre- group and post-group of the IV lens group are increased, i.e. when the radiuses of curvature of the converging surface A of the pre-group and the diverging surface of the post-group are reduced, various abberations can be compensated under balanced state. Thus, the lens system can be shortened by increasing the refractive indexes of the pre-group and post-group of the IV lens group.

Title: Method and device for sowing
Inventor: ATAKE MINORU
IPC: A01C7/04
Filed: 1992-08-21
Abstract: PURPOSE:To surely sow a constant number of seeds at the sowing positions of a sowing bed without relating to the sizes and shapes of the seeds by separately dropping the seeds in a stand for receiving the seeds and subsequently stopping the fine oscillation of a chute to stop the discharge of the seeds when the discharged seeds reach a constant number. CONSTITUTION:When an oscillation device 7 is driven, fine oscillations are given to a chute 1, and seeds 3 are transferred to the downstream side in an aligned state toward a discharging end 1a. The seeds reached to the discharging end 1a are separately dropped, and the number of the seeds is counted with a counting sensor S1, while the dropping seeds pass through a holding frame 8. The counting signals are inputted into a control means 19, and the dropped seeds are charged in a stand 9 through a hopper 11. When a prescribed number of the seeds 3 are counted, a source for driving the oscillator 7 is stopped with the control means 19, and the fine oscillations of the chute 1 are stopped to stay the seeds on the chute 1. The discharging of the seeds from the discharging end 1a is immediately stopped. Thereby, the seeds can accurately be sowed by the accurate setting of the number of the seeds required for one sowing operation and by the accurate counting of the seeds.

Title: On-vehicle display device
Inventor: HIRANO TOSHIHIRO
IPC: B60R11/02
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent an injuury, damage or deformation due to hitting a light shielding hood when it is unnecessary during the day by providing a moving means for moving the light shielding hood in the service state at the time of detecting darkness outside a vehicle. SOLUTION: When headlights are lighted because of getting dark outside of a vehicle, a headlight blink detecting part 9 detects the actuation of a headlight switch 8 and transmits it to a control part 10, and the control part 10 sends an output signal to a roller driving part 12. A light shielding hood drive mechanism 30 is therefore put in a hood open state to shield image light from a display 3 to the windshield, and the image of the display 3 is not projected in the front view of a driver through the windshield. When the periphery of the display becomes light, the control part 10 receiving an input signal from an illuminance detecting part 7 sends a luminance down output signal to a backlight luminance switching part 11 and sends a hood closing output signal to the roller driving part 12. An ill condition such as an injury and damage can therefore be prevented.
