Filed: 1986-04-10
Abstract: PURPOSE:To execute good optical modulation even with incident light having an optional polarizing component and to prevent an increase of a cell gap by constituting a diffraction grating of an optical member having rugged shapes of a checkered pattern in the plane. CONSTITUTION:This optical modulator is provided with two sheets of substrates 7, 7, the diffraction grating 2 disposed to one of the substrate 7 surfaces, which face each other, between the substrates 7, a refractive index variable material 1 packed between the diffraction grating 2 and the substrates 7, and means for controlling the refractive index variable material 1. The diffraction grating 2 is constituted of the optical member formed with the plural rugged shapes having the checkered pattern in the plane, by which diffraction is generated regardless of the polarizing direction of the incident light. The good optical modulation is thereby executed even with the incident light having an optional polarizing component at the time of making the optical modulation such as passage and shielding of light by utilizing the refractive index variable material such as liquid crystal 1 and the diffraction grating 2. In addition, an electric field can be efficiently impressed to the liquid crystal 1 without expanding the cell gap and the simple optical modulator which does not decrease the effective height of the diffraction grating 2 is obtd.

Filed: 1985-04-18
Abstract: PURPOSE:To reduce the size of a memory by transmitting the arithmetic result via a data communication means and carrying out consecutively the prescribed arithmetic processing through the 2nd arithmetic processing means when the 2nd arithmetic processing means requests the transmission of the arithmetic result obtained by the 1st arithmetic processing means. CONSTITUTION:An arithmetic processing part 4 supplies repetitively data and a calculating indication for execution of calculations through a keyboard/display control part 3 until an equal (=) key is pushed on a keyboard 1. When the equal (=) key is pushed, the result of calculation is delivered to a display 2 through the control part 3 for display. Then the part 4 knows that an arithmetic processing part 6 requests the input of data through a communication part 5 and sends the result of calculation displayed on the display 2 to the part 6 through the part 5. At the part 6 a new calculation processing is applied to the result of calculation. This can avoid the duplicated package of the processing functions and therefore reduces the size of a memory.

CONSTITUTION:A core part 2 of a wooden material 1 is formed with a through-pass hole 3 having an inner diameter of 3cm. A water-proof (liquid) processing is applied in the through-pass hole 3. In this case, a thermal medium flowing pipe 4 is fitted so as to have the above-mentioned waterproof process. As the wooden material 1, material having a rate of moisture less than 15% (preferably, a rate of moisture or about 10% or less) as its degree of driness is applied. This is applied because a feature of the wooden material is realized under a more preferable condition. Normally, in order to dry a woody material up to a rate of moisture of about 10%, its drying period is extended and its drying facility is large in scale. However, a presence of the through-pass hole 3 enables an easy drying to be performed and further the through-pass hole 3 may act as a thermal radiator.

Abstract: PURPOSE:To make it possible to display a large amount of digital informations along with radar video informations, by displaying radar video informations by a PPI display system and digital informations by a television raster system in a time division manner. CONSTITUTION:Radar video input signals RVI are successively stored in a temporarily storing memory 1 in a real-time system and a vertical return wire synchronous signal VSYNC of a television raster is inputted to the memory 1 while radar video output signals RVO are continuously read at a high speed from the memory 1 during the vertical period of the television raster.

The switch 2 changes over the video displayed on the apparatus 3 by the signals VSYNC. During a period other than the vertical return wire period of the television raster, digital signals DV converted to a television raster system are displayed on the apparatus 3 through the switch 2.

Title: Fertilizing equipment in rice transplanter
Inventor: YONEDA YASUSHI
IPC: A01C19/00
Filed: 1990-03-30
Abstract: PURPOSE:To improve the work accuracy for fertilization through preventing clogging troubles or fertilizer loss by interlockedly connecting a power-drawing shaft to a screw conveyor via a flexible shaft. CONSTITUTION:Since the driving of a screw conveyor 55 is made by withdrawing power from a chain case 57 located at an intermediate position of a transmission case 56, a special driving system is not required. Furthermore, the power- drawing shaft from the chain case 57 is installed before a unit clutch for each row stopping at the rear of each planting case 20a, 20b and behind a planting clutch in a planting transmission case. Therefore, despite planting stop at any row, the screw conveyor 55 is rotated without stopping, thus preventing cloggings due to the fertilizer and/or mud within a pipe 54. And, during suspension of planting work for all rows by planting clutch 'off', the screw conveyor 55 is automatically stopped, thus preventing fertilizer loss, leading to improving work accuracy.
