Title: Cooling device for electric machine
Inventor: TANAKA TAKESHI
IPC: B61C17/00
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To thinly form a heat receiving plate without lowering cooling efficiency by a method wherein the mounting part of an electric machine is provided between the heat receiving plate and a refrigerant flow path. SOLUTION: The heat generated on a self-extinguishing type element 12 and a snuffer resistor 13 during operation is transmitted to heat receiving plates 6A and 6B, the heat moves by transmitting to the refrigerant, e.g. water, which is forcedly circulated in the first refrigerant path and the second refrigerant flowing path. The water, which is heated up by absorbing heat, flows as shown by the arrows in the diagram, and it is cooled by radiation from a heat radiating part 11 where heat is exchanged by the outside air. The cooled water is sent out to the refrigerant flow path in the heat-receiving plates 6A and 6B by a circulation pump 10, and the self-extinguishing type element 12 and the snubber resistor 13 are continuously cooled.  As the heat-receiving plates 6A and 6B are provided in such a manner that the mounting part of the first and the second refrigerant flow paths and the mounting part of the electric machine are provided separately, the heat-receiving plates 6A and 6B can be formed small in size.

Abstract: PURPOSE:To eliminate the need for a package by forming sequentially a 1st high sound velocity film, a piezoelectric film and a 2nd high sound velocity film onto a substrate and providing an electrode to a border between the piezoelectric film and the 1st high sound velocity film and/or between the piezoelectric film and the 2nd high sound velocity film, thereby protecting the vicinity of the electrode. CONSTITUTION:A 1st high sound velocity film 1 is formed on a silicon substrate 4 by forming a diamond carbon film whose film thickness is 1-10mum by the ion vapor-deposit method or the like. An AIN piezoelectric film 3 is formed on the film 1 by the sputter method or the like and an aluminum electrode whose film thickness is nearly 200nm is formed on the film 3 by the vacuum vapor-deposition method. The electrode is processed into a fine interdigital electrode 5 by the photo lithography method to form both the input and output electrodes to be of the same shape as a pattern whose line and space are both 1.2mum. Moreover, a 2nd high sound velocity film 2 is formed onto the film 3 and the electrode 5 similarly to the case with the film 1. Thus, the vicinity of the electrode is protected and no package is required and the cost is reduced.

Abstract: PURPOSE:To prevent damage of a photo-sensitive drum caused by external light or operator's hands or tool and the like, prevent a poor transfer and to reduce spacing in an image forming device and to provide a small-sized device by a method wherein when a protection cover is placed at its escaping position, a sheet transporting passage is formed by a protection cover. CONSTITUTION:When a main body device is closed toward a direction (a), a supporting member 1b is cooperatively operated to move a shutter member 1a to its escaping position. At this time, the shutter member 1a approaches a resist roller 10 to transport a sheet member 13 in synchronism with a rotation of a photo-sensitive drum 2 and a corona charger 6 so as to form a transporting passage for the sheet member 13. A transferring electric field restricting member 1d arranged along a longitudinal direction of a drum at a corona charger 6 of the shutter member 1a may restrict a transfer electric field in such a way as a transfer electric field from the corona charger 6 may not act against the developer agent forming the visual image upstream of its rotating direction than a transfer region on the photo-sensitive drum 2. With such an arrangement, it is possible to prevent damage of the photo-sensitive drum caused by the operator's hands, or tool and the like, to reduce a spacing in the device, to provide small-sized device and to prevent poor transferring operation.

Title: Anode tantalum oxide pellet of electrolytic capacitor
Inventor: STEPHENSON DONALD H
IPC: B32B15/04
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To prevent an internal 'excessive heat point' from forming by a method, wherein a heated electrolyte is periodically extracted from the inside of a valve metal structure. SOLUTION: When a compressed valve metal powder structure is anode- oxidized, the heated electrolyte is periodically diffused from the inside of the structure. This periodically allows a forming voltage to be maintained ranging over a sufficient period of time for making the electrolyte heated inside an anode pellet flow out before enforcement of a continuous anode oxidization process. In other words, the forming voltage diffuses the electrolyte inside the pellet and is periodically and reliably maintained ranging over a sufficient period of time for being replaced with a fresh electrolyte supplied from an anode oxidization bath. Preferably, the forming voltage is maintained over about 20 min or more. The diffusion of the electrolyte further shields a forming power source and suspends the anode oxidization pellet for a constant period of time.  Even in this case, a diffusion time of at least about 20 min is set.
