Title: Two-cycle internal combustion engine
Inventor: RA SAIZOU
IPC: F01B7/20
Filed: 1980-12-19
Abstract: PURPOSE: To raise the combustion efficiency of a two-cycle internal combustion engine, by interposing between a cylinder and an inner piston an outer piston which functions as a check valve through interaction with the inner piston, and thereby enabling to exhaust combustion gas smoothly from the cylinder.  
     CONSTITUTION: A bell-shaped outer piston 12 is interposed between a cylinder 1 and an inner piston 15, and a deflector 30 is arranged at the top of the inner piston 15. Further, the top 7 of the cylinder 1 is shaped in the form of an inverted cone. With such an arrangement, when the pistons 15, 12 are moved  downward, intake air compressed to a lower portion in the cylinder 1 is passed through ports 27 formed in the side wall of the outer piston 12 and ejected from an opening 26 radially into the cylinder 1. Here, since exhaust ports 10 are formed circumferentially in the cylinder 1, turbulences caused by movement of combustion gas produced at the time of previous explosion can be minimized considerably. By employing such an arrangement, intake air and exhaust gas can be circulated smoothly, so that it is possible to reduce fuel loss and to increase the output of an engine.

Title: Thermal head drive controller
Inventor: YAJIMA HIROSHI
IPC: B41J2/36
Filed: 1986-07-30
Abstract: PURPOSE:To obtain a uniform printing density at all times, when a battery is employed as a power source, by providing a means for detecting the temperature of a thermal head and a means for detecting the applying power, and controlling the power supply time on the basis of the detected values. CONSTITUTION:A x1 circuit 75 and a integral xdx circuit 76 detect the power being applied onto a thermal head 21 with time, and a detection signal is fed to a comparator 77. On the basis of the temperature of a heat radiation board in the thermal head 21 being obtained from a first thermister 55a and the temperature of a print paper A being obtained from a second thermister 55b, a control section 51 calculates a predetermined value which is converted into an analog signal by means of a D/A converter 78 and provided as a referential voltage to (-) terminal of the comparator 77. The output voltage from the integral xdx circuit 76 increases with time, and when said output voltage exceeds the referential voltage, the control section51 closes the gate of an AND gate 66 so as to interrupt the voltage being applied onto the thermal head 21.

Title: Method and device for correcting mask pattern
Inventor: ONUMA EIJU
IPC: G03F1/36
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a correcting method which can correct a mask pattern with high precision without any decrease in mask throughput originating from dummy defect detection at defect inspection time while minimizing increase of correction data and increase in correction calculation time by dividing a slanting-line part into minimum data. SOLUTION: The pattern 32 including the slanting line is divided into thin and long fine rectangular patterns to make the slanting line into a staircase- shaped line. When plural evaluation points are arranged along the outer periphery of a design pattern 32, the evaluation points 30 are arranged at the respective short-side parts 40 of the fine rectangular patterns corresponding to the staircase-shaped slanting line 32b. The transfer image obtained when exposure is performed under specific transfer conditions is simulated by using the photomask of the design pattern given the evaluation points 30. Differences between the simulated transfer image and design pattern are compared at every evaluation point.  When the design pattern is deformed depending upon the differences compared at every evaluation point so that the differences become small, the lengths of the fine rectangular patterns 40 are adjusted to correct the shape of the staircase-shaped slanting line.

Title: Production of plated steel stock excellent in adhesion
Inventor: SHIMOGOORI KAZUTOSHI
IPC: C23C14/02
Filed: 1987-07-17
Abstract: PURPOSE:To produce a plated steel sheet capable of keeping excellent corrosion resistance by forming a plated layer vapor-deposited with Al having specified thickness on steel stock preheated at specified temp. and thereafter lowering preheating temp. and forming the plated layer vapor-deposited with Zn or Zn-Al alloy thereon. CONSTITUTION:A steel sheet having a cleaned surface is preheated at 200-350 deg.C in the nonoxidizing atmosphere and then a plated layer vapor-deposited with Al having 0.1-2mu thickness is formed thereon. Thereafter the temp. of this steel sheet is adjusted at 150-200 deg.C and the plated layer vapor-deposited with Zn or Zn-All alloy is formed thereon. In this method, adhesion of the layer vapor-deposited with Al for the steel sheet is not sufficiently insured at preheating temps. lower than 200 deg.C and on the other hand, the properties of the steel stock are changed at the temps. higher than 350 deg.C and furthermore adhesion of the layer vapor-deposited with Al is deteriorated. Further sufficient adhesion is not obtained at thickness smaller than 0.1mu of the layer vapor-deposited with Al and effect for improving adhesion is not enhanced more than it even at thickness larger than 2mu. Adjustment of the temp. of the steel sheet at a time for forming the Zn-base vapor-deposited layer is performed to prevent a state of vapor deposition from being made unstable because once vapor- deposited Zn is again vapor-deposited.

Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To attain high-speed operation with an optical processing type and to stably synchronize an exciting light phase with a signal phase so that the shaping of signal light pulse waveforms may be executed by amplifying the same phase component as the exciting light of input signal light and attenuating the orthogonal phase component. SOLUTION: This optical amplifier is composed of a phase sensing optical amplifier section 12, an exciting light source 13, an exciting light phase control section 14 and optical branching sections 15-1 to 15-3. The exciting light phase is controlled so as to maximize the average intensity of the output signal of the phase sensing optical amplifier section 12. Namely, the exciting light phase of the exciting light source 13 is controlled so as to be synchronized with the phase of the input signal light branched by the optical branching section 15-1. The exciting light phase control section 14 detects part of the output signal light branched by the optical branching section 15-2 by a detector of the narrow band region and controls the exciting light phase so as to maximize the detecting current.  Consequently, the peak phase of the signal light pulses and the exciting light phase are controlled so as to be synchronized and the signal light pulses are subjected to waveform shaping in the amplification section 12.

Abstract: PURPOSE:To obtain ceramic hollow spheres of a metal oxide with high resistance to heat, pressure, and chemicals by preparing an emulsion by mixing a first and second oils with an aqueous solution of a water-soluble metal compound and decomposing and removing aqueous phase and oil phase from the emulsion. CONSTITUTION:An aqueous solution of a water-soluble metal compound is added to a first oil, if necessary a surfactant is added, and then the mixture is mixed by a supersonic vibration, a homogenizer, etc. By the mixing, the first oil is made fine oil drops and dispersed in the aqueous phase to give an O/W-type emulsion. Then, when this O/W-type emulsion is added to a second oil and mixed in the same way, a second oil layer is formed outside of the aqueous solution layer surrounding the oil particles to give an O/W/O-type emulsion. When water is removed from this O/W/O-type emulsion and heating at a prescribed temperature is carried out, the oils which compose the emulsion is evaporated and decomposed and thus ceramic hollow spheres of a metal oxide are obtained. By this method, hollow spheres having high resistance to heat, pressure, and chemicals are obtained.
