Patent JP-H0467309-A (JP)
Title: Manufacture of magnetic head
Inventor: UMETSU KATSUTO
IPC: G11B5/127
Filed: 1990-06-29
Abstract: PURPOSE:To prevent track deviation by cutting the track groove of a pair of cores with the same track width and forming the small track width by means of etching at the time of forming the cores with different track width. CONSTITUTION:The track widths 2a and 2b of a pair of the cores 1a and 1b are worked by the same width in the magnetic heads having the different track widths and etching is executed so that one core 1b comes to have the track of the small width. Thus, the occurrence of track deviation owing to the malfunction of a track pitch within the junction block of the core can be prevented because track work can simultaneously be executed even if the track widths of the confronting cores 1a and 1b differ.

Title: Bit excellent in chip discharging property
Inventor: OKINO HISASHI
IPC: B23B51/04
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To improve a chip discharging property, to reduce rotation resistance, to prevent the stop of a bit and to facilitate the boring work by forming chip discharging grooves extending coaxially and spirally from U-shaped notch sections arranged radially at the annular tip section of the bit on a hollow truncated conical shank outside face. SOLUTION: When spiral chip discharging grooves 8A are bored on the hollow truncated conical shank outside face 9 of a bit 1A, the grooves 8A exert the force extruding the chips generated by the tips 3 of annular tip sections 5 and the tips 4 of step sections 10 toward an annular junction 11 when the bit 1A is rotated in the spiral direction. The tips 4 are fixed to the trailing side sharp sections 3A of the U-shaped notch sections 6A of the annular tip sections 5 and the chip discharging groove trailing side step sections of the hollow truncated conical shank outside face 9 by bolts 4A respectively. The depth D1 of the U-shaped notch sections 6A is set equal to or larger than the thickness T of an object to be bored which is a molding made of a polyethylene plastic as D1 >=T.

Title: Method and apparatus for mounting component
Inventor: SAKURAI HIROSHI
IPC: B23P21/00
Filed: 1992-07-01
Abstract: PURPOSE:To shorten a cycle time and to enhance a component mounting efficiency by eliminating to superpose a component to be sucked with a parallel beam. CONSTITUTION:A plurality of components K1, K2, K3 are disposed in a detecting area of a laser beam unit for emitting a laser beam L so as not to be superposed with the beam L, and continuously detected. Since the components K1, K2, K3 are continuously detected (i.e., without retracting) and sequentially mounted at predetermined positions, a cycle time from sucking the components K1, K2, K3 to mounting is shortened to enhance mounting efficiency of the components K1, K2, K3.

Title: Burner of pressurized atomization type
Inventor: HIRASAWA FUSAO
IPC: F23D11/24
Filed: 1987-07-13
Abstract: PURPOSE:To improve the degree of the mixing of fuel and air and facilitate the supply of secondary air by providing a flame stabilizer with an opening only in the direction of the whirl of the air and at the same time piercing secondary air discharge holes in a large number and in many stages and providing a fuel evaporation plate at a position close to the secondary air discharge holes in the first stage inside the stabilizer. CONSTITUTION:A flame stabilizer 7 is formed as a box only one side face of which is cut off and three other side faces of which are closed, and all the air that goes through this flame stabilizer 7 flows only in one direction of this opening. The air passing through this opening gains sufficient swirling force to improve the state of mixture of fuel and air. Secondary air discharge openings 12 in a large number are pierced in many stages through the circumferential wall of a cylinder 9 in a combustion chamber. A fuel evaporation plate 14 that is made of ceramics and installed near the air discharge ports 12 which are positioned in the first stage performs moisture absorption for the fuel at the beginning of its ignition and when the temperature of the evaporation plate 14 is raised, it performs its role as an evaporator, and at the same time it catches the atomized fuel which has a large diameter or atomized fuel droplets which are not uniform to evaporate the fuel smoothly. Further, the secondary air discharge ports 12 replenish the air which is not sufficient in the mixture of the fuel that was evaporated by the fuel evaporation plate 14 and the air so that the combustion is maintained in multiple stages.

Title: Burner flame detector
Inventor: MIYAMAE SHIGEHIRO
IPC: F23N5/08
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To simplify the structure of a probe and indentify the signal change of the AC component of the light of a weak flame of an ignition burner even when the ignition burner of a corresponding main burner is ignited while a separate main burner is burning and a furnace is in a very bright state. SOLUTION: In a burner flame detector, the light of the flames of a main burner 4 and an ignition burner 20 is caught by a probe 23 having an optical filter 49 for a main burner, an optical filter 50 for an ignition burner and a bundle optical fiber 51 and guided to an amplifier unit 24. The light taken out by wave separators 53 and 55 in the amplifier unit 24 is photoelectrically converted by photoelectric converters 33a to 33c. Electric signals 35a to 35c undergo a logarithmic compression by logarithmic amplifiers 37a to 37c to take out DC components 36a to 36c and pass the electric signals 35a and 35b through bandpass filters 39a and 39b to take out AC components 38a and 38b of required frequency.

Title: Arc tube of high luminance discharge lamp
Inventor: HAYASHI KOICHI
IPC: H01J61/30
Filed: 1991-06-19
Abstract: PURPOSE:To provide an arc tube which is a thin arc tube with mechanical strength and anti-corrosion characteristics to which a sealing member can be firmly fixed. CONSTITUTION:In a arc tube 1J a sealing member 4 is brought into contact with end faces of both end flanges 1g (the flange outer diameter: about 5.2mm), and a sealing member 4 is firmly fixed with a large amount of sealing material. Since the tube is of transparent alumina made of fine crystal particles and a grain boundary phase is not formed, mechanical strength (bending strength, Weibull coefficient) from room temperature to discharging time temperature is improved comparing with the conventional arc tube. As a result, because an emission region tube path 1h can be made as thin as 0.2mm or less, a heat capacity of the arc tube itself is reduced, the temperature of the arc tube is raised quickly to a fixed temperature, a starting time can be shortened.

Title: Analyzer constituted by use of ion source
Inventor: ADACHI TATSUYA
IPC: H01J49/10
Filed: 1982-10-05
Abstract: PURPOSE:To prevent any shaded areas to be seen from an ion gun, and enable the analytic accuracy of depth direction to be greatly improved by causing the axis of an ion beam to coincide with that of an electron beam. CONSTITUTION:An ion-beam deflecting part 5 is installed in the middle of an electron-optical system through which an electron beam passes. An ion source 3 and a lens 4 are installed at the entrance along the axis of the ion beam. Owing to such a constitution, an ion beam produced from the ion source 3, after being controlled in its diameter and current by means of the lens 4, is introduced into the ion-beam deflecting part 5. In this deflecting part 5 working as a mass analyzer of primary ions, ions with a uniform mass number are allowed to pass and their traces are made to coincide with the axis of the electron beam. Since a magnetic field is effective in such a case, a sector mass generated by an electromagnet is used for the ion-beam deflecting part 5. A detector 9 is used to detect and analyze various kinds of information obtained from a sample, such as secondary electrons, secondary ions and Auger ions. Various kinds of detectors are used according to respective purposes.

A neutral aqueous solution of an inorganic salt in 1-10wt% concentration and a water-insoluble organic solvent are brought into contact with the solution after the completion of the reaction, and the organic solvent phase is then separated from the aqueous solution phase. The resultant organic solvent phase is then distilled under reduced pressure at <=100 deg.C bottom temperature to distill away the organic solvent and phenol therefrom. An organic solvent consisting essentially of an aromatic hydrocarbon is then added to the resultant bottom residue to crystallize the aimed compound. Thus, the aimed compound useful as a raw material for organic phosphorus insecticides is isolated in high purity and yield from the above- mentioned solution after the completion of the reaction without resinification.
