Title: Scanning probe microscope
Inventor: YANO AYUMI
IPC: G01N37/00
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain an accurate image even if the image is scanned speedily when sampling a moving image by previously generating the amount of operation to a Z-directional drive mechanism on a next scanning based on image data that are obtained by previous scannings. SOLUTION: Data on amount of operation in Z direction of a probe 2 at each scanning position of a sample W are stored at an image memory 5. A part 7 for generating a signal on the amount of foresight operation reads the previous amount-of-operation signal of the image memory 5, uses an xy scanning signal on a next scanning as a timing signal, and generates an amount-of- foresight-operation signal so that the same amount of z-axis operation can be obtained at the same xy scanning position.  Then, the amount-of-operation signal from a controller 24 and the amount-of-foresight-operation signal from the part 7 for generating a signal on the amount of foresight operation are added by an addition point 32 and a signal after the addition is supplied to a piezoelectric driver 22 as the amount-of-operation signal, thus increasing the probability following the surface of the sample W faithfully due to the Z-direction drive mechanism and obtaining a highly accurate image information at a relatively high scanning speed.

Title: Combustion chamber of internal combustion engine
Inventor: KAWAMURA HIDEO
IPC: F02B3/06
Filed: 1986-04-12
Abstract: PURPOSE:To restrain the exhaust of white smoke, NOX and HC in all usable load running conditions to provide combustion of satisfactory output fuel consumption by improving injection ratio with a fuel injection nozzle having a plurality of jets and distributing fuel concentrically into a combustion chamber without passing fuel through a forced region. CONSTITUTION:Air compressed by a piston 2 rapidly raises the temperature of an adiabatic layer 6 higher than the vaporizing temperature of fuel even at the start in extremely low temperature. A fuel injection nozzle 7 is disposed to open to the downstream side of a swirl S at the outer periphery of a combustion chamber 4 so that fuel sprays f1...f4 collide with the adiabatic layer 6 and a portion of the sprays atomized and vaporized flows into a natural stream S2 of swirl. The remaining portions flow together with the swirl S while being deposited and formed as a fuel film vaporized on the wall surface with uniform wide film thickness. Thus, the outer surface of each fuel film is vaporized by the wall heat of adiabatic layer 6 and compressed air heat and flows together with the natural stream S2 of swirl to be fired and burnt. The vaporization of fuel film is promoted by the combustion energy to provide gradual vaporization and combustion. Thus, combustion with few NOX, noise, white smoke and output fuel consumption is provided even on low temperature start.

Abstract: PURPOSE:To halve a photoresist process and to make it possible to form an offset gate having no mesh shift by a method wherein asymmetrical stepped opening parts are formed by a two-layer resist and two-time exposure method to form an asymmetrical T type gate electrode and an self-alignment offset formation process utilizing this electrode is adopted. CONSTITUTION:An active layer 2 is formed in a semiconductor substrate 1 by an ion implantation or the like, an negative photoresist A is applied and the resist A other than a part A' to correspond to an opening part H is exposed to light. Moreover, an negative photoresist B is applied and the resist B other than a part B', which is a part on the non-exposure part A' and corresponds to an opening part H' having an area wider than that of the opening part H, is exposed to light. At this time, the central axes of the unexposed parts A' and B' are ready-shifted right and left. The resists A and B are developed to form the stepped opening parts H and H', a gate metal film is applied from over these opening parts and a T type gate electrode 4 is formed by a lift-off method. High-concentration doped layers 3a and 3b are formed by an ion implantation using the asymmetrical T type gate electrode 4 as a mask. Since the electrode 4 is asymmetric, an offset structure is obtained in a self-alignment.

IPC: H04N9/12
Filed: 1983-05-12
Abstract: PURPOSE:To offer a color television receiver using a liquid crystal display body operated under the existing color television standard system by providing a means processing the three primary chrominance signal demodulated from a video signal into a signal supplied to the liquid crystal display body. CONSTITUTION:The three primary chrominance signals obtained by a primary color synthesis circuit 5 are inverted at each vertical period by the analog switches 14, 15, 16 of a primary chrominance signal processing circuit 6, an alternate signal of three primary colors at each vertical period is applied to output terminals V1, V2 and V3 at each horizontal period by analog switches 18-26 and applied to each picture element of the crystal display body 8 corresponding to the three primary colors by shift registers 30-32. Since a transmission signal is processed to correct the gamma characteristic of the CRT at the image transmission side, the gamma correction suitable to the liquid crystal diaplay body is applied to the three primary color signals, then a nonlinearity is provided to a primary chrominance signal synthesis circuit 5. The phase of the demodulated carrier applied to a color difference signal demodulating circuit 4 is adjusted by setting the demodulating axis of the color difference signal to a proper value depending on the dye of a color filter as to the reproducibility of color.

Filed: 1982-05-18
Abstract: PURPOSE:To prevent the exfoliation of a spinel epitaxial film by thermally oxidizing the whole in dried oxygen in the thermal oxidizing method forming silicon dioxide SiO2 to a boundary between the spinel epitaxial film and a silicon single crystalline substrate. CONSTITUTION:When magnesia spinel is grown onto the silicon single crystalline substrate of a (100) crystal face orientation in an epitaxial manner and thermally oxidized for five hr by dried oxygen at one atmosphere at 1,200 deg.C, exfoliation is not generated at all even through quenching after thermal oxidation through the temperature of thermal oxidation is higher than oxidation in steam. The diffraction intensity of a (400) diffraction peak increases by approximately one and a half times as large as that before thermal oxidation, and single crystallinity is, on the contrary, improved.

Title: Electronic timepiece
Inventor: MAEHIRA YOSHIAKI
IPC: G04C10/00
Filed: 1980-06-20
Abstract: PURPOSE:To eliminate the difference in battery life run-out announcing functions (BLA) due to the variance in circuits by detecting the oscillation stop of a quartz oscillating circuit, thereafter increasing the amplification factor of the amplifier of the quartz oscillating circuit thereby restarting oscillation and displaying that the life of a battery is near the termination. CONSTITUTION:The signal 9 emitted from a quartz vibrator fetches a suitable signal from the midway of a frequency dividing circuit DIV by a waveform forming circuit MCD, and converts the same to differentiating pulses 10, by which a charging transistor Nd is turned on intermittently, and a capacitor C is charged. The capacitor C is discharged by a discharge resistance R, and therefore, when the oscillation stops, the output 13 of a reset flip-flop FF is fixed at an H level after a constant time determined by a time constant Rc, thereby turning on Pc and Nc, and restarting the oscillation of the quartz. At the same time, information is fed to a decoder to turn on and off the display and to announce the run-out of battery life.

Filed: 1983-05-16
Abstract: PURPOSE:To manufacture the titled image sensor at low cost, and to improve an optical utilization rate by laminating and constituting a light-receiving element array, a transparent insulating film and an EL light-emitting element on a substrate. CONSTITUTION:A thin-film light-receiving element array 11, a transparent insulating film 14 and an EL light-emitting element 15 are formed on a substrate 10 in succession. The surface of an electrode 16 on the side near to the substrate 10 in the element 15 is roughened so that electroluminescence is diffused-reflected from the surface, and the metallic electrode, to a section thereof opposite to the light-receiving opening section of the element 11 a hole is bored, is used. A transparent conductive film is used as an electrode 17 on the side far from the substrate 10 in order to irradiate electroluminescence to a manuscript surface and pass reflected rays from the manuscript surface 23 and enable the light-reception of the element 11. According to such constitution, a light guiding system light focusing rod lens array is unnecessitated, and the titled image sensor can be manufactured at low cost. Since an optical path between the manuscript surface 23 and the array 11 is short and the element can be fast stuck to the manuscript surface 23 completely, the utilization rate of rays is improved.
