Patent JP-S5780867-A (JP)
Title: Facsimile device
Inventor: YAMANAKA YOSHIO
IPC: H04N1/00
Filed: 1980-11-08
Abstract: PURPOSE:To record control information easily control information artificially, by expressing types of control information by colores different in brightness. CONSTITUTION:A photosensor 3 reads out not only control information from a control information recording region 2a but also transmission data from a transmission data recording region 2b and gives the read signal to a control information extracting circuit 4. The extracting circuit 4 extracts only control information and gives an electric signal corresponding to control information to a potential level discriminating circuit 5. Meanwhile, a reference potential generating circuit 6 sets potential levels for colors which express types of control information and are different in brightness, and these potential levels are given to the potential level discriminating circuit 5. The discriminating circuit 5 compares the inputted potential with reference potentials and gives the output potential to a discriminating circuit 7 successively. The discriminating circuit 7 generates a coded signal having information such as a resolution and an automatic destination address in accordance with combination of inputted potentials.

Title: Color filter and color liquid crystal display
Inventor: ARAGAKI TAKEJI
IPC: G02B5/20
Filed: 1989-06-22
Abstract: PURPOSE:To prevent the color mixing at the time of display by segmenting a picture element region to plural small regions and forming the colors of these small regions such a manner that the entire part of boundary regions is visually recognized substantially as the neutral tints of the colors constituting the picture element regions. CONSTITUTION:The color of the boundary regions is easily visually recognized as the neutral tints of the colors of the picture elements to be drawn as a whole if the small regions constituting the boundary regions are so disposed that another one color occupies in the boundary regions of certain specific two colors. Striped color filters of red 1R, 1<1>R, green 1<1>G, and blue 1B, 1'B are, therefore, disposed on segment electrodes 2a to 2c and the color filters of red 1R, 1'R green 1G, 1'G and blue 1B, 1'B are formed like dots between the segment electrodes 2a to 2c. The boundary regions are recognized as the neutral tints, such as gray, when, for example, three primary colors of light are used in this way: therefore, the color mixing at the time of the visual recognition is effectively prevented.

Title: Idling engine speed control method for internal combustion engine
Inventor: UEDA KATSUNORI
IPC: F02D43/00
Filed: 1990-06-15
Abstract: PURPOSE:To restrict fluctuations in engine speed at the time of idling by controlling the ignition timing and the fuel supply quantity in response to the magnitude of load when change in the operating state of a load device. CONSTITUTION:When an internal combustion engine 12 is controlled to be idled, and for example, when a head lamp switch 60 is switched from OFF to ON, or from ON to OFF to suddenly increase or decrease load on the engine, an electronic control device 40 delays or advances the ignition timing, and increases or decreases the fuel supply quantity in response to the magnitude of load applied by a head lamp to the engine 12. Thus, since engine torque can be promptly increased or decreased in response to changes in the operating state of a load device, fluctuations in engine speed at the time of idling can be minimized.

Title: Strain, stress and water leakage detector
Inventor: YANAGIDA HIROAKI
IPC: G01N27/04
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To grasp the strain and stress of an object accurately and inexpensively through a simple constitution and to detect water leakage over a wide area by applying a voltage to a conductive member provided in a structural member. SOLUTION: When the concrete material 4 in a structure 5 is cracked to cause water leakage from the ground into the concrete material 4, conductive fibers 2A, 2B are shortcircuited electrically. Consequently, a high current flows into an AC ammeter 9B from an AC constant voltage power supply 8 and the water leakage can be detected. When the concrete material 4 is subjected to an external force due to earthquake, for example, the external force acts on grid composite members 3A, 3B and the electrical resistance of the conductive fiber 2A is varied depending on the strain or deformation caused by the external force. Consequently, the strain and stress of the structure 5 can be determined easily by measuring a current corresponding to the variation of electrical resistance incident to generation of strain through the AC ammeter 9A and then processing the measurements.

Filed: 1990-06-20
Abstract: PURPOSE: To increase the efficiency of a semiconductor cathde in a way different from the prior art by setting the thickness of a p-type region at a maximum of 4 nanometers or less. CONSTITUTION: A semiconductor device has an n-type region 3 forming a p-n junction 8 with a p-type region 4 on the main surface 2 of a semiconductor main body 1.
