Title: Insert body expansion molded product
Inventor: OZAKI NORIO
IPC: B29C33/12
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To prevent an end part of a foam from being separated from an insert or being broken when a mold is released in manufacture by a method wherein an engaging projected part engaging an end part of the foam with the insert by being buried in the end part of the foam, is formed on an outer surface of the insert. SOLUTION: An expansion molding tool 40 constituting a molded product cavity 43 composed of a top force 41 and a bottom force 42 is used, an insert 11 is arranged on a mold face of the top force 41, and liquid expansion raw material P is casted into the cavity 43. Then, the liquid expansion raw material P is expanded to fill the cavity 43. Thereby, an engaging projected part 15 of an end part 12 of the insert 11 is buried, and a foam 21 is fixed by engaging with an outer face of the insert 11 via the engaging projected part 15. Thereafter, a molded product wherein the insert 11 and the foam 21 are integrated is released above the bottom force 42. In that case, since the end part 22 of the foam 21 is surely engaged with the end part 12 of the insert 11 with the engaging projected part 15, there is no fear of being separated or broken.

SOLUTION: When connecting a nickel hydrogen battery pack 2, battery temperature is detected by a battery temperature detection circuit 16 from a Vcc potential voltage of a resistor 15 and a thermister 5. If battery temperature is 0 to 40 deg.C, then charging control circuit 19 is charged by setting a constant current circuit 10 to 3c amperes. Also, when a nickel-cadmium cell is connected, the battery temperature is detected by the battery temperature detection circuit 16 from Vcc partial voltage of the resistor 15 and the thermister 5. If this battery temperature is between -10 deg.C to 60 deg.C, then the charging control circuit 19 charges the battery by setting the constant current circuit 10 to 5c amperes.  Charging time can be shortened to the characteristic limit of each battery pack by changing the size of charging current depending upon the battery temperature and the kind of battery pack.

Title: Thermal stability testing method for rotor
Inventor: UMEMURA SUNAO
IPC: G01M99/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To enable an unsteady thermal bend of a rotor of a gas turbine or a steam turbine to be exactly checked before the rotor is incorporated. SOLUTION: A rotor 11 is supported by bearings 12, 13 and connected to a driving motor 15 by a coupling 14 to be rotatably supported. An intermediate part 21 of the rotor 11 and the face of a flange 20A are partially covered with a chamber 10 to be hermetically sealed with seals 16, 17. Fluid 19 with a large heat transfer coefficient is heated by a heater 61 through a pump 70 and then injected into the chamber 10 through a valve 8, and thus a large temperature difference is produced between this part and other parts. Thus, the temperarure difference between a normal working face part and a defective working face part on the joint surface of the flanges 20A and 20B is largely increased. Since vibration is also generated when the temperature difference is large, troubles due to thermal unbalance can thus be checked.
