Title: Apparatus for analyzing particle image and recording medium recording analysis program therefor
Inventor: KOSAKA TOKIHIRO
IPC: G01N15/02
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To form a correct particle size distribution by measuring particle data such as an area, a circumferential length, etc., of picked-up particle images, obtaining a roundness of the particle, forming analysis data for a parameter representing the roundness, and outputting a distribution diagram. SOLUTION: A particle suspension is sucked from a suction pipette 1 through a sample filter 2 to a sample-charging line 3 above a flow cell 5. A sheath syringe 4 is driven to guide the liquid into the flow cell 5. At the same time, a sheath liquid is sent from a sheath liquid bottle 6 to the flow cell 5 through a sheath liquid chamber 7. The flow of the particle suspension is surrounded by the sheath liquid and reduced to be flat. The particle suspension flows in this state in the flow cell 5. A pulse light is projected from a strobe 8 approximately every 1/30 see. The suspension is picked up by a video camera 10.  An image-processing apparatus 11 obtains particle data of a projection area, a circumferential length, etc., of each picked-up particle image, calculates a roundness, forms a histogram of the roundness and obtains information related to a shape (particularly a surface roughness) of particles.

Title: Stress applied magnetic core
Inventor: TSUGE HIROSHI
IPC: C22C38/00
Filed: 1994-07-01
Abstract: PURPOSE:To incease permeability at the time of DC magnetic field superposition, by applying compression stress in the range of elastic deformation, in the rolling direction. CONSTITUTION:The plane face orientation of crystal grains of a magnetic core constituted of an Fe-Si alloy foil is (110), and the rolling direction is [110]. Compression stress in the range of elastic deformation is applied in the rolling direction. As the method, the bending of the Fe-Si alloy film is used. The foil is wound in a troidal form, and a magnetic core to which constant compression stress is applied is easily formed. The compression stress on the foil surface is larger than or equal to about 10kg/mm<2> and smaller than about 40kg/mm<2>. By applying the compression stress, the permeability mu at the time of DC magnetic field superposition exhibits a very large value in a small magnetic field in the vicinity of zero, and shows a constant permeability mup in a specific range of magnetic field larger than the above-mentioned small magnetic field. Thereby a magnetic core having a constant high permeability can be manufactured, and a small-sized switching power supply of high efficiency can be realized.

Title: Magnetic recording medium and magnetic powder for recording medium
Inventor: ANDOU HARUO
IPC: C09D127/04
Filed: 1983-08-18
Abstract: PURPOSE:To obtain a magnetic recording medium having desirable electromagnetic conversion property by using needle-shaped gamma-Fe2O3 powder with different properties from those of conventional one, having the predtermined values of particle void volume, particle superficial area and the intensity of face (210) by X-ray diffraction. CONSTITUTION:Aqueous suspension of Fe(OH)3 is heated in alkaline condition under the existance of a crystallization controlling agent to produce alpha-Fe2O3 powder having the low particle void volume. This powder is subjected to heat reduction and oxidized to obtain needle-shaped gamma-Fe2O3 powder whose void volume is less than 5vol% on the average, preferably less than 2vol%. Thus the particles can be prevented from constituting polymagnetic regions, and the magnetic layer can be packed with high packing density. Further, the intensity of the face (210) determined by X-ray diffraction can be less than 5% of that of the face (311), and the specific surface area of the particles can be 24-30m<2>/g. A predetermined phosphate surface active agent is added to this powder, using vinyl chloride - vinyl acetate copolymer or fibrous resin containing OH or -COO radicals as a binding agent, and a magnetic layer is formed on a non-magnetic substrate. In such a manner, a magnetic recording medium with high sensitivity and low noise can be obtained.

Title: Correction method applied to freezing forecast device using microprocessor
Inventor: MIKAMI KAZUO
IPC: G01W1/00
Filed: 1979-11-20
Abstract: PURPOSE: To make a forecast more accurate by storing temperatures measured at each spot in a memory, reading from the other memory expected temperatures forecast prearranged hours earlier, a measurement time and correcting a forecast value prearranged hours later based on a correction value which is the difference between a forecast value and an actually measured value.  
     CONSTITUTION: Temperatures measured by a road surface thermometer 14 are converted to digital signals by means of a processing circuit 15, and are read by a microprocessor every five minutes. Then they are stored in a register 17 and then are transfered to an area 18 for RAM 12. The mictoprocessor calculates a forecast road surface temperature based on data on the area 18 every five minutes and the temperature is stored in the area 20 for RAM 12 through the intermediary of a register 19. The microprocessor 11 corrects an calculated value of a forecast value prearranged hours later based on a correction item which represents the difference between an actually measured temperature at the present measurement time and a forecast value corresponding to the present time which was read out from the area 20. If the corrected calculated value reaches freezing temperature, a freezing forecast signal is outputted to a line 20 through an interface 10. Thus, it is possible to make the forecast more accurately.

When the character comes to the position of the designated brand display window 43, the sheet 44 is stopped and the inputted brand name appears at the designated display position. Thus, the brand name is safely and easily set and changed.

Title: Monitor moving system
Inventor: KAI MASAHARU
IPC: G08G1/0962
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a monitor moving system allowing an operator to set it at a monitor angle as he/she feels suitable by a simple and fewer operations, by providing a tilt control means for varying a monitor panel angle at multi- steps within a preset angle width, and an angle width setting changing means for changing setting of the angle width. SOLUTION: Every time a tilt button 12 is pushed once, a monitor panel 10 is changed in a tilt angle by a preset tilt angle width at multi-steps. For example, when the tilt angle width is set to 5 degrees, the tilt angle is changed every 5 degrees. Namely, when the tilt button 12 is pushed once in a complete closing state, the tilt angle is 5 degrees. Also, when the setting of the tilt angle width is changed to 10 degrees, the tilt angle is changed by 10 degrees, every time the tilt angle button 12 is pushed once. A change in the setting of the tilt angle width is performed by using a joystick 13 on the monitor panel 10. Thus, even though the tilt angle is large, which an operator feels suitable, it is possible to reduce the number of operations at a tilt operation end.

Filed: 1990-06-11
Abstract: PURPOSE:To prevent metal contamination and cross-contamination due to sputtered emission from a disc by so supporting a wafer irradiated with a particle beam as to be separated from the surface of the disc constituting a support mechanism. CONSTITUTION:An ion beam is irradiated onto a wafer 15, and as well onto a disc 10 constituting a support mechanism. In particular, an aluminum atom or an atom group is emitted from the disc 10, due to sputtering with the ion beam. Also, an injected atom such as phosphorus, boron and arsenic is made to spring out in this case. The wafer 151, however, is supported above the surface of the disc 10 with a columnar support section 131, and cryopumps 22a and 22b are provided near the disc 10. As a result, the emitted aluminum atom or atom group, and the sprung-out cross-contamination atom are absorbed by the cryopumps 22a and 22b, failing to reach the wafer 151. According to the aforesaid construction, the surface oft he wafer 151 becomes free from the deposit of the aluminum atom or atom group, and also is protected against the re-injection of the cross-contamination atom. As a result, a device of high reliability can be obtained and the production yield thereof can be improved.
