Then, when the balloon 21 is expanded until the gas pressure inside the balloon 21 becomes nearly equal to the gas pressure inside the container 1 or until it reaches a preset expansion size, the valve parts 18A close the small holes 16 in the direction of B by a restoring force to prevent the back flow of gas. Thereafter, when a flange part 19 is manually or automatically pulled out, the check valve 14 is separated from the valve body 8, and the balloon 21 floats up to the length of a rope 22.

Title: Stand for acoustic equipment
Inventor: OGATA IKUO
IPC: G10C3/00
Filed: 1986-04-23
Abstract: PURPOSE:To sufficiently faithfully reproduce the original sound quality without any electric revamping for an acoustic equipment system or the like by providing the surface layer part made of a bainite cast iron and the internal part made of a pearlite cast iron to the titled stand so as to absorb almost entirely the resonance of the sound by the acoustic equipment. CONSTITUTION:The stand is provided with the surface layer part made of a bainite cast iron and the internal part made of a pearlite cast iron. When a bending stress is exerted to the stand 1 by the vibration energy propagated from the acoustic equipment 3, the bainite material and the fine pearlite material are subjected to elastic deformation and the vibration energy to deform the stand is absorbed by the friction in the bainite part, the mutual friction at the boundary between the bainite part the fine pearlite part and the friction of the fine pearlite part. Thus, the resonance operation of the stand by the vibration energy of the acoustic equipment is attenuated quickly.

Title: Uninterruptible power-supply device
Inventor: NODA MAKOTO
IPC: H02J9/06
Filed: 1993-04-21
Abstract: PURPOSE:To repair the fault of a rectifier with time to spare. CONSTITUTION:While a device is normal and it is receiving commercial power- supply power, the commercial power-supply power is rectified by a rectifier 13 and converted into an alternating current by an inverter 14, and the laternating current is supplied to a load 17 (Fig. 1A). When the device is normal and a service interruption is caused, the direct current of a storage battery 18 is supplied to the inverter 14 and converted into an alternating current, and the alternating current is supplied to the load (Fig. 1B). When the device becomes faulty, the commercial power-supply power is supplied directly to the load 17 through a bypass 24 (Fig. 1C). When a service interruption is caused in this state, the direct current of the storage battery 18 is converted into an alternating current by the inverter 14, and the alternating current is supplied to the load (Fig. 1D). Consequently, as compared with a case where the rectifier becomes faulty and the output of the storage battery 18 is converted immediately by the inverter 14 and supplied to the load, it is not required to repair the rectifier in haste.

Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To prevent the fuming and the burning of parts and to improve the safety by stopping energizing a fixing device and informing a user of the detection of an abnormal operation at the time of turning on a main switch again, in an image forming device in which energizing is cut off when an abnormal operation condition is detected. SOLUTION: When the main switch 1 is turned on, a fixing heater 6 generates heat through an AC control plate 2 and heating temperature is measured by a thermistor 5, and then temperature control is performed. The energizing control of the heater 6 is checked based on the previously set operation condition. When the abnormal operation condition is detected by the check, energizing the image forming device is cut off. When the main switch 1 is turned on again, the heater 6 is not energized because a CPU 3 stores the abnormal operation condition, for example, that abnormal voltage is inputted. Finally, 'code display' showing that the abnormal high voltage is inputted is displayed on the display panel, etc., of an operation part 4.
