Filed: 1984-03-19
Abstract: PURPOSE:To enhance the reliability and to reduce the size and cost by detecting both the output voltage and current of a high voltage transformer at the secondary side, and feeding back them to the primary side to control an oscillator of the primary side. CONSTITUTION:A power source 1 has a high voltage transformer T, and an oscillation transistor Tr is connected with the primary side coil N1 of the transformer T. Further, a charger load RL of a copying machine is output through a rectifier of rectifying diodes and a spark discharge preventing resistor R2 from the secondary side coil N2. In this case, an output voltage detector 6 and an output current detector 8 and comparing means 10 for comparing the both outputs are provided between the primary side and the secondary side of the transformer T and output to the controller 2 of the transistor Tr. Thus, the controller 2 increases or decreases the base current to be applied to the transistor Tr in response to the output signal from the comparing means 10 to obtain the prescribed output drooping characteristic.

Title: Etching method
Inventor: OJIRI HIDEHIRO
IPC: H01L21/302
Filed: 1990-03-05
Abstract: PURPOSE:To prevent crack of a resist film from occurring at a low-temperature etching by forming a resist film when a specified patterning is performed on a surface of a substrate to be etched, implanting ions into the surface of the substrate for hardening a surface of a resist film, and then performing etching of the substrate with the resist film as an etching mask. CONSTITUTION:A resist film 2 where a specified patterning is made on a surface of a substrate to be etched 1 is formed, ion is implanted into the surface of the substrate 1 for hardening a surface of a resist film 2, and then the substrate 1 is etched with the resist film 2 as an etching mask. Namely, by implanting ions onto the substrate 1 where the resist film 2 was subjected to patterning, a solidified (carbonized) layer 3 is formed on the surface of the resist film 2 and anion implantation layer 4 is formed on the substrate surface which is to be etched. This carbonized film 3 is much harder than the original resist film 2, thus preventing crack of the resist layer 2 due to this char layer 3 when the temperature of the substrate 1 is reduced.

Abstract: PROBLEM TO BE SOLVED: To obtain an image generaring device for biocular observation which can be drastically miniaturized and is inexpensive and light in weight by constituting a scanning means of a single two-dimensional scanning member scanning luminous flux for a right eye together with luminous flux for a left eye. SOLUTION: A two-dimensional scanning member 6 scans in the two directions, that is, the horizontal direction and the vertical direction in the case of reflecting incident light. After the luminous flux for a right eye scanned by the member 6 in the two directions forms a two-dimensional image on a diffraction grating 8R, it is guided toward an observer's right eye ER and projected to the right eye ER through an eyepiece optical system 5R. Meanwhile, after the luminous flux for a left eye scanned by the member 6 in the two directions forms the two-dimensional image on a diffraction grating 8L, it is guided toward an observer's left eye EL and projected to the left eye EL through an eyepiece optical system 5L.  As a result, the virtual images of the two-dimensional images on the gratings 8R and 8L projected through the optical systems 5R and 5L are observed with the respective eyes ER and EL.

Title: Measuring method for organismic sample
Inventor: KIKUCHI TATSUJI
IPC: G01N1/28
Filed: 1995-02-17
Abstract: PURPOSE:To detect inulin accurately at high sensitivity by additionally providing a step for removing monomeric saccharides and proteins from a sample through a diaphragm. CONSTITUTION:Glucose and fructose are separated, along with other monomeric compounds, from a sample through a diaphragm by precise filtering, ultrafiltration, reverse osmosis or dialysis to leave inulin. Proteins are removed previously from the sample. Inuline is then converted into fructose through hydrolysis. In this regard, inorganic acid, e.g. sulfric acid, hydrochloric acid or perchloric acid, is employed and the concentration, reaction temperature and reaction time thereof are selected appropriately depending on the type of acid. The sample obtained through hydrolysis is then subjected to measurement of fructose by high performance liquid chromatography equipped with an electrochemical pulse detector or enzymatic measuring method and coloring method.

Abstract: PURPOSE:To provide for oneself a considerable part of the enthalpy increase in a Rankine cycle heating and vaporization process by the heat transfer between a Rankine cycle and the cooling and heating cycles installed outside the Rankine cycle. CONSTITUTION:In cooling and temperature raising cycle, the fluid which flows in a circulation passage is pressurized by a compression pump P-2 and jetted out from the nozzle of a jet pump JP-1. Therefore, the intermediate or low pressure gas which recovers heat from the fluid on a Rankine cycle side by a low-pressure heat exchanger E-1 and compressed by a compressor C-1 is inhaled through a conduit connected to the low pressure side, and mixed with the high-pressure liquid jetted out from the nozzle and forms high-pressure liquid jetted out from the nozzle and forms high-pressure liquid. Since heat is transferred to the Rankine cycle side fluid by high-pressure heat exchangers E-3 and E-2, the input calorific heat of the external energy by a heat exchanger E-4 for temperature rise can be reduced.
