Title: Bobbin
Inventor: KATAI TAKETOMO
IPC: B41J31/00
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a bobbin, which is excellent in workability for reeling a thermal transfer sheet up thereto and which can be reeled up with a general purpose converting machine. SOLUTION: This bobbin 1 is one bobbin 1 for feeding and/or reeling up the thermal transfer sheet. At at least one side of its end part, a gear 4 is provided. By setting the outer diameters l1 and l2 of both the end parts 2 and 3 to be smaller than the outer diameter l3 of a central part 5 except both the end parts, the external form of the bobbin has no locally protruded portion, resulting in requiring no chucking sensor and easily realizing the fixing of the bobbin and the reeling-up of the thermal transfer sheet. Further, since the bobbin has no flanged part, no exclusive touch roll corresponding to the shape of a feeding bobbin is employed at the taking-up of the thermal transfer sheet in its manufacturing, resulting in having a workability with high general purpose properties.

Title: Apparatus for measuring pipe thickness
Inventor: MIYAZAKI KATSUMASA
IPC: G01B21/08
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To apply a complex piping system for reducing measurement time by estimating thickness distribution, based on a temperature distribution in a natural cooling process of a pipe which has been heated into an isothermal state. SOLUTION: A plurality of thermocouples 11 re connected to a pipe 21 whose thickness is to be measured, and while heaters 12 placed on an upstream and a downstream of the pipe 21 are controlled by a temperature controller 13, heat is applied so that the regions of the pipe 21 to be measured are at isothermal state (approximately 100 to 350 deg.C). When the pipe 21 reaches a prescribed isothermal state, the heaters 12 are turned off, and a temperature distribution of the pipe 21 being cooled spontaneously is measured by a temperature distribution measuring device (thermograph) 14, and a computer 15 transfers temperature data taken at arbitrary times and arbitrary coordinates of the pipe 21 to a computer 16.  The computer 16 compares the temperature data at arbitrary time and coordinate as the optimum value for heat conduction analysis results of each thinned form, which are stored in a heat conduction analysis data base 16 for determining the thickness distribution of the pipe 21 (maximum thinned depth, maximum thinned angle, thinned length, and thinned angle).

Title: Antenna mount
Inventor: KITAYAMA MITSUMASA
IPC: G01S3/42
Filed: 1992-11-20
Abstract: PURPOSE:To prevent tracking from being delayed by detecting an error component from the horizontality of a stable stand caused by acceleration operated to the stable stand to support an antenna and correcting with the turning of two axes. CONSTITUTION:A stable stand 15a is freely turnably supported by turning shafts 14 and 15. Since the stable stand 15a is almost horizontally supported regardless of the oscillation of a ship, an Az axis 26 is matched with the azimuth of an artificial satellite S and an E1 axis 28 is matched to the elevation angle of the satellite S by a driving device for respectively turning the Az axis 26 and the E1 axis 28. However, directing error is generated by the inclination of the stable stand 15a due to the acceleration sometimes. In this case, the inclining angles of the first and second turning shafts 14 and 15 in the respective turning directions are detected by first and second detectors 20 and 21. The corrected angles of the Az axis 26 and E1 axis 28 are operated by these detected inclining angles, the turns of the respective axes 26 and 28 are corrected by the driving device, and an antenna 29 is directed to the artificial satellite S.

Filed: 1991-12-20
Abstract: PURPOSE:To easily set a password while securing secret holding ability by sending the password specified on a cordless key unit, and receiving and registering the password by an information processor main body. CONSTITUTION:The key input of the cordless key unit is sent from a light emission unit 35 and received by the photodetection unit 21 on the information processor main body side. The main body once receiving the password and a protection item stores the password and corresponding protection item temporarily in a RAM 22 for the photodetection unit which is powered by a battery at all times. Then when the main power source of the main body is ON, the stored data are recorded in one of memory parts 15, 17, 19, and 20. When the main power source is OFF, on the other hand, the main body enters a stand-by state, but when the power source is turned ON, the data stored in the RAM 22 are recorded in the memory part by a CPU 10. Thus, the main body and key unit are separately stored to improve the maintenance, and the setting can be done without turning ON the main body power source.
