Abstract: PURPOSE:To obtain a stable alumina coating film high in insulation property by thermally spraying an alumina powder on a material to be thermally sprayed, which is heated and kept at a specific temp., and cooled slowly. CONSTITUTION:A metallic plate 10 to be worked is heated to 2000-3000 deg.C by applying a plasma flame 9 on the material 10 to be worked placed on a iron plate-made pedestal 11 heated and kept at 200-400 deg.C. After that, the metallic plate 10 is thermally sprayed with alpha-alumina powder introduced into a equipment with a carrier gas.

Title: Integrated infrared video device
Inventor: ONO SHIGEO
IPC: H04N7/18
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To realize an infrared video device which doesn't require the use of an AC adapter. SOLUTION: When a commercial AC power source is connected to the AC input of a power switch 1, a switching power source 2 converts the AC input voltage to a DC voltage. A relay 3 is set to the excited state by this DC voltage, and the contact of the relay 3 is switched to the side of a terminal N.O. The output voltage of the power source 2 is supplied to a DC-DC converter 4. When a battery is connected to the DC input of the switch 1 and the AC power source is not connected to the AC input, the relay 3 is set to the non-excited state, and the side of a terminal N.C is selected. The DC input voltage from the battery is supplied to the converter 4. Thus, this device is miniaturized as the whole in comparison with a conventional device using an AC adapter.

Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To form MR images composed of plural tomograms by graphically positioning a desired layer based on outline photographing and image-forming the desired layer from a 3D data set 1. SOLUTION: In the example of a relatively strongly curved back spine 1, the outline photographing is prepared first. That is, it is prepared based on a 2D set in the form of an arrow-like cross section. Then, the layers to be connected are determined on an image surface by a cursor 3 and the 3D data set is prepared. The 3D data set is not extended to the entire object area and is spread only to the layers 1a-1e to be image-formed. Which object area is to be detected is automatically discriminated based on lines L1-L5 set in a vertical direction for instance for the direction of the area. For instance, in the case of desiring to detect only the layers 1b, 1c, 1e and 1f, the object areas O1 and O2 indicated by both broken lines are detected. Thereafter, a three- dimensional image data set is obtained by three-dimensional Fourier transformation from a three-dimensional raw data set.
