Abstract: PURPOSE: To obtain separated microcapsules each having a prescribed surface and a prescribed particle size and extremely suitable for preparing pesticidal formulations in a highly simple operation without requiring an additional dispersing agent. CONSTITUTION: The microcapsules containing a water-miscible herbicide (preferably a herbicide such as urea, sulfonyl urea, chloroacetanilide or triazine compound, an insecticide or acaricide such as thiourea, or a germicide) or an easily volatile solvent are obtained by rapidly stirring an aqueous solution of a precondensate of urea and formaldehyde in the molar ratio of 1:3.0 to 1:3.5, especially 1:2.9 to 1:3.1, in an acidified aqueous dispersion of the water- immiscible herbicide or easily volatile solvent. The solvent can be removed from the capsules by a simple method or by a conventional fluidized bed drying method, and the obtained hollow microcapsules are suitable for encapsulating a liquid or a pesticide having a low melting point.

Title: Magnetic head
Inventor: SUGIMORI MASAHIRO
IPC: G11B5/187
Filed: 1988-10-26
Abstract: PURPOSE:To obtain a magnetic head which can prevent the occurrence of a pseudo gap and secure the firm junction between two ferrite cores by adding a magnetic layer made of niobium 'Permalloy(R)' between a magnetic metallic film and the ferrite core. CONSTITUTION:A magnetic thin film layer 7 is formed between a magnetic metallic film 4' and an I-shaped ferrite core 1. The layer 7 is made of a mag netic material, e.g., the niobium 'Permalloy(R)' having the thermal stability. This material has a high magnetic transformation point, i.e., 900 deg.C and has no magnetic change even at a temperature which melts the glass of a high melting point. Therefore the layer 7 can keep its magnetic stable state despite the heat which is produced when the bonding glass 6 is melted for junction between two ferrite cores 1 and 2. As a result, the stable state is secured for the interface between the layer 7 and both cores 1 and 2 respectively. Further more the output waveform of a magnetic head has no distortion owing to the absence of a nonmagnetic part. Thus both cores 1 and 2 are firmly jointed to each other with no deterioration of the bonding intensity.

Title: Vapor-phase chemical reaction equipment
Inventor: TSUTSUMI YOSHITSUGU
IPC: H01L21/205
Filed: 1992-10-07
Abstract: PURPOSE:To shorten the exhaust time and improve the operating efficiency of an equipment, by installing an auxiliary exhaust mechanism of large conductance and exhausting the gas in a mixing chamber. CONSTITUTION:After a wafer 3 is introduced into a susceptor 1 in a vacuum vessel 4, gas in the vacuum vessel 4 is evacuated by using an evacuation part 61, via an evacuation piping 6. In this case, a shower head exhaust valve 51 is opened, and the gas in the mixing chamber 22 is exhausted mainly by shower head exhaust piping 5. Since the conductance of the shower head exhaust piping 5 is very large as compared with the conductance of small holes formed in a shower head part 2, the exhaust time is remarkably shortened as compared with the case where the gas is exhausted without using the shower head exhaust piping 5.

Filed: 1990-10-09
Abstract: PURPOSE:To enable a living organism to be measured even within a high ion concentration solution and strength to be improved by performing flame-spraying machining of a surface of a metal to be used as an electrode or using a sintered metal for an electrode for minimizing influence of an electrode polarize. CONSTITUTION:Ion concentration and composition change in a culture system including a cell, the cell itself becomes a resistance constituent within solution, change itself of cell concentration becomes a fluctuation factor of electrical conductivity, and an amount of living organism cannot be measured at a frequency range where influence of electrical polarize cannot be ignored, thus requiring use of a metal which is subjected to flame-spraying machining for minimizing influence of electrical polarize or a sintered metal. As the flame- spraying electrode, a metal is fused and turned into powder spray shape by compressed air and then is sprayed onto a surface which is roughened previously for achieving mechanical adhesion and the influence is stopped within a low-frequency band. Also, a powder metal is pressed, hardened, and heated to obtain an alloy for the sintered metal. Thus an electrode for measuring living organism amount.

Title: Method for measuring insulation resistance of non-grounded circuit
Inventor: MATSUNO TATSUJI
IPC: G01R27/18
Filed: 1989-10-17
Abstract: PURPOSE:To measure the accurate insulation resistance by grounding the non- grounded circuit through a switch and a capacitor and detecting an effective and an ineffective component which flow through the capacitor. CONSTITUTION:The non-grounded circuit 1 is grounded through the capacitor C0, the terminal voltage across which is amplified by a high-input-impedance amplifier AMP and inputted to synchronous detectors M1 and M2. The M1 and M2 are applied with the secondary line output of a synchronous transformer T2 directly or through a phase shifter PS to output the effective voltage from the M1 and the ineffective voltage value from the M2, so that they are stored in an arithmetic circuit CP. Then the switch SW is switched to connect the C0 to the circuit 2 and the outputs of the M1 and M2 are storaged similarly. The CP calculates the insulation resistance by specific arithmetic according to the stored voltage values. Consequently, any new signal source need not be used and the accurate insulation resistance can be measured.

Title: Cctv camera
Inventor: YAMAMOTO KUNIO
IPC: H04N5/33
Filed: 1992-10-08
Abstract: PURPOSE:To eliminate deficient sensitivity by focusing an image based on a visible light and an image based on infrared rays by separate optical systems and forming each image so as to make the images coincide with one face. CONSTITUTION:A visible light is fed to an infrared-ray filter 1 in a 1st optical system, the focus of a 1st lens 2 is implemented to form the image of a visual light onto the image forming face of a CCD 9. An infrared-ray 12 is fed to a visual light filter 5 in a 2nd optical system, the focus the 2nd lens 6 is regulated to form the image of infrared rays onto the image forming face of the CCD 9. Since the spectroscopic sensitivity characteristic of the CCD 9 has the sensitivity in a visual light area and an infrared-ray area 12, the optical energy of both images is converted into an electric signal by photoelectric conversion. Furthermore, even when the ratio of the components of the visible light and the infrared rays of a light source at night is subjected to change, since the visual light and the infrared rays in 1st and 2nd optical system are focused separately, no defocusing is caused.
