Abstract: This invention provides a porous film (76) useful as a fresh fruit and vegetable wrapping material which is obtained by forming a large number of small recesses (74) in an organic film (69) and which does not allow permeation of water, bacteria, and viruses, but allows permeation of a gas, e.g., the oxygen gas or the carbon dioxide gas, and water vapor. The porous film (76) includes the organic film (69) and the large number of recesses (74) formed in the organic film (69) and having an average opening width of 0.5 µm to 300 µm and inner surfaces exhibiting affinity. 
     The invention provides as well a porous film manufacturing apparatus comprising: 
feed means for feeding an elongated organic film (69; 
a recess-forming unit (29) including a first rotatable roll (9) having a surface on which a large number of dielectric particles (10), each having sharp pointed portions and a Mohs hardness value of not less than 5, are deposited, and a second roll (16) which is rotatable in a direction reverse to a rotating direction of the first roll and having a surface on which a dielectric layer is formed, the first and second rolls being arranged to cause the elongated organic film to pass therebetween, and either one or both of the rolls being movable in a direction along which the first and second rolls (9), (16) are aligned; 
pressure control means (53), arranged near two end portions of either one of the rolls (9), (16) of the recess-forming unit (29), for controlling a pressure applied from each of the rolls to the elongated organic film (69); and 
high-voltage supply means for supplying a high voltage to the first roll.

Abstract: In a procedure and a circuit for measuring the inductance of a coil, preferably of a sensor in which the inductance depends on a distance to be measured, a voltage is applied in pulses to the coil via a sensing resistor. The voltage drop across the sensing resistor is compared with a reference voltage, the voltage drop exceeding the reference voltage at the beginning of the measurement and dropping below the reference voltage at the end of the measurement. An output signal assumes a first one of two possible voltage levels if the voltage drop is smaller than the reference voltage. <IMAGE>

Abstract: The invention relates to a method and a device for burying a pipeline (11) in a bed (22) under water, in which a pipeline is laid on the bed and a device resting on the bed over the pipe is moved along the pipeline, while during this movement the device removes the bed material on either side and under the pipe, so that a trench (22) into which the pipeline sinks is formed, in which method the bed material on either side of the pipe is first removed, so that furrows running essentially parallel to the pipe are formed, and the bed material remaining between said furrows and on which the pipe is lying is then removed. The furrows are preferably formed by pushing away the bed material in the same way as with a plough, and the abovementioned bed material (24) remaining between the furrows is removed by sucking it away, so that a furrow into which the pipeline sinks remains. The bed material to be sucked away may first be loosened up by spraying with water to form a pumpable mixture. 
     A device for use of the method preferably comprises ploughshares (2) for making the furrows and a dredging pump unit for sucking away the bed part remaining between the furrows. The burial of the pipeline can be considerably simplified by using a high-pressure pump and spray nozzles. Flexibly mounted slippers facilitate the movement of the device over the bed.

Abstract: A color cathode ray tube having an intermediate layer between the face plate and the tricolor phosphor layer. The intermediate layer is a selective light absorption layer or a neutral filter layer. The selective light absorbing function and the uniform light absorbing function are imparted not to the functional film on the outer surface of the face plate but to the intermediate layer formed on the surface of the face plate facing the electron gun, namely, on the inner surface of the face plate. The mechanical strength of the functional film is thus enhanced.

Abstract: PCT No. PCT/EP92/02029 Sec. 371 Date May 11, 1994 Sec. 102(e) Date May 11, 1994 PCT Filed Sep. 3, 1992 PCT Pub. No. WO93/05293 PCT Pub. Date Mar. 8, 1993.A piston diaphragm pump operable for delivering doses of liquids such as surfactants, or wetting agents, for example, includes a pump piston that is reciprocally moveable within a pump tube that encloses a pump pressure chamber. The pump piston is electromagnetically driven against the force of a return spring by a magnetic coil that surrounds the pump tube. In addition, a pump diaphragm is rigidly clamped about an inner circumference to a portion of an upper end of the pump piston. The outer circumference of the pump diaphragm is rigidly clamped about its periphery between upper and middle housing sections. One side of the diaphragm faces a suction chamber, and the other side faces a pressure chamber. A longitudinal bore, that encloses a pump piston provided with a piston valve, extends centrally through the pump diaphragm and links the pressure chamber to the suction chamber. In order to obtain the same pump capacity with reduced pump lifts, without requiring a specially sealed guidance of the pump piston in the pump tube, a pressure chamber located on the side of the pump diaphragm opposite to the suction chamber is designed as an additional pump pressure chamber that is constantly connected to the piston longitudinal bore that leads to the pump tube pressure chamber by cross-channels arranged in the pump piston behind the piston valve.
