Title: Compressor
Inventor: SEKIDA MASUMI
IPC: F04C28/28
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To easily install a compressor even in a narrow space, by integrating a relief valve which is opened when the gas pressure in a closed housing which includes a compressing mechanism driven by an external driving source through an electromagnetic clutch, is abnormally risen, in such a manner that it is not projected from an outer peripheral face of the housing. SOLUTION: In a compressor which is integrated in an air conditioner for a vehicle, and in which a compressing mechanism included in a closed housing, is driven by an external driving source through an electromagnetic clutch, a relief valve 50 is screwed into a screw hole 55 penetrated through the closed housing 1, from an inside of the housing 1, and is sealed by an O-ring 56. When the gas pressure of a high pressure chamber 31, is abnormally increased, the gas is entered into the relief valve 50 from an inlet 51 thereof, pushes and opens a valve 52 which is pressed by a coil spring 53, and is exhausted outward through a hole 54. Thereby the outside dimension of the compressor is reduced, and the collision of the relief valve 50 with the other equipment, can be prevented when the compressor is installed in an engine room.

Title: Voltage control method for uninterruptible power supply
Inventor: NOZAKI TOSHINOBU
IPC: H02J9/06
Filed: 1993-01-13
Abstract: PURPOSE:To eliminate the effect of voltage drop across a semiconductor switch on the output voltage from an uninterruptible power supply by applying the detected voltage drop across the semiconductor switch to a voltage control system. CONSTITUTION:Output from a detector 9 for detecting voltage drop across a semiconductor switch 4 is applied to a voltage control system so that the output voltage is compensated upon turn ON of a switch 5 or the semiconductor switch 4. In other words, voltage is controlled to match the input side voltage of the semiconductor switch 4 with a voltage reference before the switch 5 is turned ON whereas the voltage is controlled such that a voltage, corresponding to the voltage drop across the semiconductor switch 4, is applied to the voltage control system upon turn ON of the switch 5. Consequently, output voltage from an inverter 2 increases by an amount corresponding to the voltage drop across the semiconductor switch 4 thus producing an effect for nullifying the apparent voltage drop across the semiconductor switch 4. This method eliminates the effect of voltage drop across the semiconductor switch 4 on the output voltage from an uninterruptible power supply.

Abstract: PURPOSE: To effectively reducing the area of the blank of a large section with less number of rolling devices and roll the same to the material of a smaller section by using the specific rolling rolls consisting of eccentric rings and making the rolling mills movable in parallel with the material advance direction.  
     CONSTITUTION: The rolling rolls 1 (2, 3, 4) which are formed as eccentric rings and are so constituted that the barrel length width b 0  of the portion being a length diameter L with respect to the rotating center axis E is narrow and the barrel length width B of the portion being a short diameter S is wide (Figs. a, b) are disposed in opposition to the material to be rolled 5 and are so disposed as to be parallel movable in the advance axis direction of the material to be rolled 5 (Figs. c, d). When the rolling is started while the rolls 1W4 are being revolved at the rotation peripheral speed higher than the feed speed of the material to be rolled 5, the rolling mills reduce the area of the material 5 while moving this so as to pull the same and when the face-to-face distance between the rolls becomes larger than the material 5, the material is once put into a no-load state and is then pushed back in the direction opposite to the advance direction of the material 5 by hydraulic cylinders or the like, thence again the material 5 is pressure-contacted and the rolling work is repeatedly continued.
