Title: Optical coupling structure
Inventor: YASUDA TOSHIMICHI
IPC: G02B6/122
Filed: 1993-04-22
Abstract: PURPOSE:To connect an optical waveguide and optical device varying in mode field diameter of light with lessened light loss by forming a hologram on the end face of the core of an optical waveguide substrate. CONSTITUTION:The optical waveguide substrate 1 is composed of the core 2a and a clad 3a which is formed on its outer periphery and has the refractive index lower than the refractive index of the core 2a. An optical fiber 4 is composed of the core 2b and the clad 3b as well. The hologram 6 is formed on the end face 5 of the substrate 1. This hologram 6 is formed by applying a photosensitive agent film on the end face 5 of the substrate 1 to form the patterns of the hologram or directly etching the end face 5 by using a mask. The light emitted from the core 2a of the substrate 1 is changed in mode field diameter via the hologram 6 and is made incident on the optical fiber 4 by having the mode field diameter equal to the mode field diameter of the optical fiber 4 and, therefore, the loss of light is minimized.

SOLUTION: In a horizontal control apparatus for body height of a combine, which controls the height of the machine body by horizontally moving it, when the output of the vehicle speed sensor 90, which detects the travelling speed of the machine body, is higher than a specified value, the following are checked: a steering means is directed in turning, a straight advance detection switch 93 is off, a stock-side detection sensor 91 of a depth automatic controlling means is off, and a reaping switch 92, which shifts on-off of a reaping clutch by a working clutch lever, is on. When all the above conditions are satisfied, the horizontal control is inhibited, and the body height horizontal control is conducted with a lag time before the horizontal control inhibition is released.

Title: Manufacture of printed-wiring board
Inventor: YAMASHITA HIDETOSHI
IPC: H05K3/20
Filed: 1993-04-22
Abstract: PURPOSE:To obviate such defectives as exfoliation and defective bonding of patterns halfway in steps by a method wherein conductor patterns held on a bonding film capable of intentionally changing the bonding power thereof are integrated with a substrate and then the bonding power is decreased so as to mechanically release the bonding film only. CONSTITUTION:A substrate 5 having a trench part 5 is coated with a transfer bonding agent 8 and then another substrate 4 is pressed against the substrate 5 using a jig 9 and the bonding agent 8 to stick both substrates 4 and 5 on each other. At this time, conductor patterns 1 and the trench bottom surface of the substrate 5 are tack-set to be brought into contact with each other through the intermediary of the bonding agent 8 as the requirement for the pressurization. Next, the conductors 1 are irradiated with ultraviolet rays from the substrate 4 side to decrease the bonding power of the bonding agent 8 and then a supporting film 3 only is mechanically released. Later, the bonding agent 8 is completely set by heat treating step. Through these procedures, such defectives as release and defective bond of the patterns 1 can be obviated thereby enabling a rotary transfer to be manufactured in high yield.

Title: Driving method for liquid crystal display device
Inventor: MARUSHITA YUTAKA
IPC: G09G3/36
Filed: 1990-04-11
Abstract: PURPOSE:To facilitate a stable liquid crystal display of high picture quality by superposing a bias which has position dependency on the signal of a data line or the signal of a counter electrode facing the data line. CONSTITUTION:A binary counter(BINARY COUNTER) 51 and a logic circuit 52 are combined to constitute one kind of D-A converting circuit, the synchronism of the DC bias DELTAV' which has the position dependency is controlled with an erasure signal CL53, and a clock signal CP54 as an original signal is processed to vary the level of an output signal OUT55. The bias which has the position dependency is superposed upon at least one signal between the signal of the data line and the signal of the counter electrode facing the data line. Therefore, the DELTAV' can be set not by driving with the DC bias DELTAV' under certain conditions, but corresponding to respective positions of TFTs in a liquid crystal panel. Consequently, no DC component is applied to the liquid crystal and problems such as a flicker and the deterioration of the liquid crystal are not caused, so that the stable display can be made.

Title: Dc-dc converter
Inventor: USUI HIROSHI
IPC: H02M3/28
Filed: 1993-04-23
Abstract: PURPOSE:To make it possible to convert input to output and reversely convert output to input, by using a control circuit for turning on and off a pair of first and third switching elements and a pair of second and fourth switching elements alternately and converting a voltage into a different level from a DC power supply. CONSTITUTION:A control circuit 34 is used for turning on and off a pair of MOSFETs 21 and 30 and a pair of MOSFETs 22 and 31 alternately with a given interruption in between. Then, the MOSFETs 21, 22, 30 and 21 have each sine-wave drain current, and each rise and fall waveform of a voltage between drain and source becomes a part of sine wave. In this way, a harmonic factor is reduced and switching noises are lowered. An overlapped current waveform with a voltage waveform is also reduced so that zero-current and zero-voltage switching is realized with a small loss in switching. Moreover, since a converted DC voltage is different from a DC power supply, input/output two-way conversion can be carried out in operation.
