Title: Minute particle transferring apparatus
Inventor: ANDO KENJI
IPC: B05C3/109
Filed: 1985-03-27
Abstract: PURPOSE:To obtain the uniform stream of minute particles and the beam formation by installing a chamber which can be vacuumed onto the downstream side of a contraction and expansion nozzle. CONSTITUTION:A contraction and expansion nozzle 1 in which the opened port area is gradually reduced from an inflow port 1a to form a throat part 2 and the opened port area is gradually increased towards an effluence port 1b from the throat part 2 is installed into a flow passage. Further, each inside of the first and the second downstream chambers 4a and 4b is vacuumed by a vacuum pump 5 so that the second downstream chamber 4b obtains the higher vacuum degree. With such constitution, the carrier gas containing the supplied minute particles flows into the downstream chamber 4 from an upstream chamber 3 through a contraction and expansion nozzle 1, and further flows into the second downstream chamber 4b. Therefore, the uniform stream of minute particles can be obtained, and the beam formation is permitted.

The liquid crystal 4 comprises for example, p-decyloxybenzylidene- p-amino-2-methylbutylcinnamate. If the electric field is impressed, the liquid crystal is orientated by C-director-5, and a dipole moment 6 of the liquid crystal molecule. As the polarities of the substrates make to the different one by using polyvinylalcohol to either of the upper and lower electrodes, when the electric field is not impressed, the liquid crystal does not have a twist structure resulting in orientating with an inclination of + or -theta against the normal line of the layer, thereby preventing the generation of a color shade and being obtained a good display characteristics.

Title: Measuring method for concentration of iodine, peroxide, oxidant and oxdase substrate
Inventor: SUZUKI HIROBUMI
IPC: G01N27/333
Filed: 1991-03-01
Abstract: PURPOSE:To measure concentration of iodine, peroxide, oxidant or oxidase substrate by using an electrode selective to anions. CONSTITUTION:Triiodide ions generated by reaction between iodine and iodide ions are measured by using an electrode selective to anions whose anion sensitive substance is quarternary ammonium compound, porphyrin acid or metal complex of porphyrin thereby determining concentration of iodine. Peroxide or oxidant is determined by measuring iodine generated by reaction between these compounds and iodine ions. Oxidase substrate is determined by having hydrogen peroxide generated at the time of enzyme reaction reacted with iodine ions and measuring iodine generated by the above reaction. Since iodine, peroxide, oxidant and oxidase substrate can be easily measured by the method of the invention, this can be utilized in various fields of chemical industry, food industry, environmental conservation or clinical examination.

Abstract: PURPOSE:To enable a low-temperature fixable toner free from speed dependence and adapted to high-speed fixing by forming a core-shell type toner obtained by subjecting the surface of a core material low in melting point to cross-linking reaction in a liquid, especially, in water with a water-soluble hardener to form an outer shell having 3-dimensional network structure. CONSTITUTION:An epoxy resin low in melting point is used for the core material to exhibit strong fixing force at a low temperature range, and the outside of the core material is reacted with the amine hardener to form the outer shell material of a thermoplastic polyamide type resin having the 3-dimensional network structure. Said hard outer shell material of the low-temperature fixable toner can be formed by adding a surfactant into a liquid, especially, water containing the epoxy resin at a temperature lower than the melting point of the resin, stirring the mixture with a proper stirrer, converting the resin powder into spherical forms to improve its fluidity, further lowering the temperature of the slurry, adding an aqueous solution of the amine hardener, stirring it, and causing the cross-linking reaction in the surface of the core material, thus permitting fixability at a low temperature of 60-90 deg.C to be enhanced.

Title: Formation of protecting film
Inventor: HAYAMA NOBUYUKI
IPC: G11B5/127
Filed: 1982-04-14
Abstract: PURPOSE:To prevent the generation of chipping when cutting a substrate material into a slider form, by forming a protecting film of a thin film magnetic head with the 1st protecting film formed by a bias sputtering process and the 2nd protecting film formed on the 1st protecting film by a normal sputtering process. CONSTITUTION:The elements of a foundation insulated layer 2, an electrode 3, a coil 6, a gap G, an insulated layer 4, an insulated filler 5 for magnetic insulation, etc. are formed on a substrate 1. Then the 1st insulated protecting film 7 is formed on the filler 5 with a bias sputtering process, and the sufficient step coverage is given to the resesses and projections of an element part with a material of high hardness (900-1,000 Vickers hardness). Then the 2nd insulated protecting film 8 is formed with a material having lower hardness than the film 7 and by a normal sputtering process. Thus the film 8 functions as a buffer material when the substrate material 1 is cut into slider forms. This prevents the generation of chipping to the film 7 and the substrate 1. Furthermore, no sag is produced when the pole height P.H. of the gap G is polished. As a result, the yield is improved.

A coming in water temperature sensor 27 detects the temperature of water which flows in an inhalant pipe 12. A gas proportional valve 24 detects the quantity of a gas which is fed to a gas burner 20. Then, a thermal efficiency is operated based on detecting signals from the coming out hot water temperature sensor 30, coming in water temperature sensor 27 and gas proportional valve 24, and the calculated thermal efficiency is compared with a reference thermal efficiency (a normal thermal efficiency which is stored by a burner controller 34). When the calculated thermal efficiency is lower than the reference thermal efficiency, the combustion of the gas burner 20 is stopped.  By this method, when the thermal efficiency decreased due to the clogging of the fin of a heat- exchanger 16, the combustion of the gas burner 20 can be safely stopped.

Abstract: PROBLEM TO BE SOLVED: To prevent meaningless image such as full white or full black images or the like from being sent due to mistake by a transmission operator or a fault of the transmitter itself in the case of making facsimile transmission. SOLUTION: An original image read by a scanner section 2 is processed by an image processing section 5 and a pixel count section 8 counts the number of black pixels of one page of original of the image data. Let the count value be C1, the number of total pixels for one page be D, and let a setting value be K1, then in the case of C1<=K1, since this means minority of black pixels, it is discriminated that a fully white image is obtained. In the case that (D-C1) >=K1, since this means majority of black pixels, it is discriminated that a fully black image is obtained. The operation section 1 displays a message denoting the respective cases to draw attention of the operator. A fact of abnormal transmission is stored to a transmission result storage section 10 with identification data to prevent transmission of meaningless image such as fully white or black images.
