Filed: 1987-12-14
Abstract: PURPOSE:To improve a separation efficiency by providing a separating wall surface shaped in a doughnut of which the ratio r/R between an inside diameter (r) and an outside diameter R is within a specified range, and a liquid separator interposed between a stock liquid chamber and a separated component chamber thus formed. CONSTITUTION:A flat-plate-shaped and doughnut-shaped channel material 13 is fixed on the left side surface of a cover 4, and on the surface of this channel material 13 opposite to the side thereof facing a concavity 8, a doughnut-shaped separating membrane (liquid separator) 14 made of polycarbonate and forming a separating wall surface is bonded partially within an extent not impairing the area of the membrane. The liquid separator in this apparatus needs to have the shape of a doughnut of which the ratio r/R between an inside diameter (r) and an outside diameter R is in the range of 0.2-0.7, and when the range of r/R is below the aforesaid value, liquid separation lowers. While the removal of the central part of the liquid separator has been considered heretofore to cause the reduction in the area of the liquid separator and the consequent lowering of a separation efficiency, the separation efficiency does not lower substantially even when the central part of the liquid separator is removed.

Title: Grease retaining structure of power cable juncture
Inventor: SATO MASAHIRO
IPC: H02G15/24
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of oil spillage by utilizing the self-shrinkage of an elastic tube having an inside diameter smaller than the outside diameter of a power cable by inserting the elastic tube into the boundary section between the cable and grease retaining metallic parts. SOLUTION: Grease retaining metallic parts 2 the end section of which is bent to have an L-shaped cross section are put on the outer periphery of a cable 1, so that a space may be formed between the inner periphery of the parts 2 and the outer periphery of the cable 1. Then a rubber tube 4 is inserted into the boundary section between the cable 1 and parts 2. Although a level difference is produced in the space between the cable 1 and parts 2, the tube 4 is made to closely adhere to both the cable 1 and parts 2 even at the spot having the level difference by providing a projection 4A on the inner peripheral surface of the tube 4 at one end. The minimum inside diameter of the tube 4 is made smaller than the outside diameter of the cable 1, and the maximum inside diameter of the tube 4 is made smaller than the outside diameter of the parts 2.  Since the tube itself shrinks, the tube 4 tightly adheres to the cable 1 and parts 2 and can prevent the occurrence of oil spillage.

Title: Device and method for detecting abnormality of intake amount detector
Inventor: MIZUTANI KOICHI
IPC: F02D41/18
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To simply and correctly detect an abnormality generated in an intake amount detector, and to appropriately detect the off-characteristic generated in the intake amount detector. SOLUTION: An abnormality detecting device of an air flow meter 43 judges whether or not the output voltage value VG of the air flow meter 43 is present in the off-characteristic region in a region in which the throttle opening TA to be outputted from a throttle sensor 44 is equal to θ or less. As a result of the judgment, if the output voltage value VG is present in the off- characteristic region, a judgment is made that an abnormality is generated in the air flow meter 43, and an abnormality display lamp WR is lit. In the region where the throttle opening TA is small, only the throttle opening TA is the parameter for the intake air volume, and the abnormality generated in the air flow meter 43 can be easily detected. Because the off-characteristic region is narrow, the offcharacteristic of the air flow meter 43 can also be detected.

These detection signals R1, R2 are transmitted to an input interface 10. A RAM 11 issues a predetermined output in accordance with the detection signals R1, R2 through an output interface 12. The drive of the pulse motor 8 is controlled by the output from the output interface 12. In this manner, the reduction of an average copying speed is prevented in a copying machine.
