IPC: G01C21/20
Filed: 1981-04-17
Abstract: PURPOSE:To simplify and miniaturize software by displaying the position of a moving body on a map on an XY table incessantly in real time. CONSTITUTION:A CPU6 computes the position X(t), Y(t) of a moving body based on the information from a bearing sensor 1 and a speed sensor 2, operates an X axis motor driving control circuit 8 and a Y axis driving control circuit 9, and moves an X axis arm 12 and a Y axis arm 13 to specified positions. Then, by utilizing a moving body position display means 14 which displays the position of the moving body on a map, the position is displayed on the map 15. When the moving body has reached the end of the map, a map setting device 16 automatically reads the address of the next map which is previously coded and memorized at the end part of the present map, retrieves the next map, and automatically set the next map.

IPC: H04N5/937
Filed: 1987-03-14
Abstract: PURPOSE:To obtain a still picture having a satisfactory resolution by reading out a video signal of two fields, when the coincidence of color signals between two fields has been discriminated, and reading out repeatedly a video signal which precedes as time, when discrepancy has been discriminated. CONSTITUTION:A video signal separated into a luminance signal and a color difference signal is stored in field use memories 3-6 being storage means at every fields period.

IPC: G01D5/56
Filed: 1978-05-18
Abstract: PURPOSE: To enhance the performance of temperature detection and simplify the circuitry in an internal combustion engine system such as an automobile, by magneto- electrically converting the magnetic field generated in a thermocouple loop connected to a thermocouple.  
     CONSTITUTION: A current I proportional to the temperature detected at a hot junction 2 of a thermocouple flows in a coil 4 connected to the thermocouple, and the magnetic flux due to electromagnetic induction passes through a magnetic path 5 and penetrates through a Hall element 6 which is a magneto-electric transducer. Therefore, the element outputs a Hall voltage UH in proportion to the density of magnetic flux passing through. This output is processed in an electronic circuit, and the detected temperature may be indicated. Thus, malfunction due to external noise, especially static induction noise, may be prevented, and the performance may be enhanced. Also, by using Hall IC, the circuit constitution may be simplified, and the coil and other parts may be designed in small modules.

Title: Bell and its tuning method
Inventor: ITAYA YOSHIKI
IPC: G10K1/10
Filed: 1994-03-04
Abstract: PURPOSE:To obtain the bell which is easily tuned by machining without spoiling the external shape by forming the inner periphery of the section so that the bell has a polygonal continuous outline consisting of short straight lines. CONSTITUTION:The shape of the bell for obtaining a target scale is set by FEM, etc., and consequently the bell which is a little thick is obtained. Namely, the bell which has a vibration frequency higher than target natural vibration frequencies of 1st order - high order is obtained, and the internal surface of the sectional shape consisting of the continuous polygon line of the straight lines is cut to obtain the specific scale. A target value of calculation found from an actual target value, a calculated value, and a measured value is calculated from a calculated value and a measured value before the tuning. Then a variation rate, i.e., sensitivity of each natural vibration frequency is found from a specific equation. Then, an optimizing method based upon natural frequency control is used to estimate the shape of the bell, i.e., the cutting quantity of the internal surface on the basis of the calculated target value. A natural value analysis is taken by FEM for the found shape of the bell and when the error is large, a shape is estimated again. When the error is less than a permissible value, data for machining are generated.

Filed: 1985-03-25
Abstract: PURPOSE:To prevent occurrence of cavitation due to shortage of fluid intake and erosion by directly returning the fluid being discharged from a fluid actuator into the first intake channel by a switching valve when the rotational speed of a pump becomes fast. CONSTITUTION:When a pump 10 runs at more than an assigned high speed, the first port 56 of a switching valve 50 is connected to the third port 58, and the fluid discharged by a fluid pressure actuator 30 is sent directly into the first intake channel 63 through the second return channel 72.

Consequently, shortage of intake fluid does not occur, thus avoiding occurrence of cavitation and also erosion and degraded durability of the pump's members due to said cavitation.

Abstract: PURPOSE: To prevent cutting of an oil film due to a big whirling force by bringing projections in parallel with the inner and outer peripheral axes of a concentric spring into contact with a bearing outer periphery and a bearing case supporting surface and supplying oil to a recess formed between the projections. CONSTITUTION: The projections 5a and 5b of a concentric spring 3 are respectively brought into contact with a supporting surface 13 and the outer periphery of a bearing metal 2 and the bearing metal 2 is supported so as to be concentric with the supporting surface 13 of a bearing case 4. A plurality of projections are provided at equal intervals in the circumferential directions of both ends of the supporting surface 13 in order to hold the concentric spring 3 in an axial direction without being moved. Lubricating oil flows through an oil supply passage 9 into a space 12a and its part is supplied through the recesses 6 of the inner and outer surfaces of the concentric spring 3 to a space 12b.  A part of the lubricating oil of the space 12a and the lubricating oil of the space 12b flow through an oil supply passage 11 into the inner surface of the bearing metal 2, forming an oil film between this and a rotary shaft 1. Since vibrations are reduced by this oil film equivalent to the depth of the recess 6 and the rigidity of the concentric spring is large, cutting of the oil film is prevented even when shaking around of the shaft is large.

Abstract: PURPOSE:To enable simultaneous formation of flat polycrystalline Si and epitaxial Si having good crystallizability by forming on an Si substrate an insulating layer subjected to patterning, and causing Si to grow on the whole surface after implanting Si ions into the insulating layer. CONSTITUTION:An SiO2 layer is formed on an Si substrate 1, and patterning is performed, thereby exposing the surface 1a of the partial substrate 1. Then, Si ions 3 are implanted into the layer 2.
