Title: Differential rotating prime mover
Inventor: YONEDA SHIN
IPC: C01G1/00
Filed: 1990-03-28
Abstract: PURPOSE:To clarify the principle and structure of a uniformly pressurizing differential rotating engine and obtain an input-saving type prime mover using a fluid pressure as a main input by constructing the prime mover so as to continue rotary motion without nearly discharging a fluid as opposed to conventional fluid engines. CONSTITUTION:The features of the aforementioned differential rotating prime mover are effective production of a difference in thrust in the normal and reverse directions due to a difference in area and shape in uniformly pressurizing a pressure receiving surface of a rotor 5 by forming the outer periphery 6 of a rotating type cylinder into an elliptical or oval shape. A stoke of relative motion is simultaneously held. Furthermore, whirling streams of a fluid in the rotating type cylinder are produced among mutual cylindrical gas chambers (9 to 12) by relative reciprocating motion of the outer cylinder interlocking with the rotation angle of the rotor 5 and the rotor 5 and enable continuation of rotating thrust without requiring inflow of the fluid from a decompression source.

Title: Orientated material, orientated substrate and surface acoustic wave element
Inventor: YAGOU AKIHIRO
IPC: H03H9/145
Filed: 1994-03-25
Abstract: PURPOSE:To obtain a ZnO film with excellent crystalinity and less unevenness and to obtain the orientated substrate having a lamination structure suitable for an element when various devices are manufactured. CONSTITUTION:The substrate is an orientated substrate having a lamination structure comprising a diamond layer and a ZnO film arranged on a face having the (111) orientation of a diamond. The surface acoustic wave element is formed by arranging an interdigital electrode onto the ZnO film of the substrate or between the ZnO film and a diamond. Since the ZnO film or the like having a function as a piezoelectric body is formed on a face having the (111) orientation of a diamond (single crystal or poly crystal), higher c-axis orientation is obtained in comparison with forming a film of the same material onto a face of other orientation.

Title: Image input device
Inventor: ARAI OSAMU
IPC: H01L27/148
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain stable image data by correcting the luminance value of image data based on the ratio of the period of an image pickup synchronizing signal and a previously set period to output image data of a fixed luminance value even when the image pickup synchronizing signal is fluctuated. SOLUTION: When an image data signal E is inputted from an image pickup control part 23, its luminance value is corrected. In this case the period of the image pickup synchronizing signal B measured by a period measuring part 22 and a fixed reference signal previously set from a reference signal generation part 24 are inputted to a luminance correcting part 25 to correct the luminance value of image data based on the ratio of them. Namely the part 25 calculates the ratio R=T2/T1 of the period T1 of the measured image pickup synchronizing signal and a reference period T2 from two inputted periods. Image data obtained by T2/T1-folding the luminance value of image data at the signal E of inputted image data is outputted as a corrected image data signal H.
