Irrigation pipe including a pipe having at least a longitudinal row of delivery holes arranged at predetermined distances and communicating with a dripping unit provided inside the pipe, and further having an inlet communicating with the inside of the pipe and an outlet communicating with at least one delivery hole. The inlets or outlets of some or all of the dripping units communicate with the inner space of the pipe or with some or all of the delivery holes through an inlet collecting channel or an outlet collecting channel or segments thereof.

A method for manufacturing a fiber aggregate formed by fiber having reforming surface comprises the steps of providing a fiber surface having thermoplastic resin at least on the surface layer thereof with a hydrophilic processing liquid containing polymer having a first portion with more hydrophilic group than the surface, and a second portion having interfacial energy different from that of the hydrophilic group, and interfacial energy substantially equal to the surface energy of the fiber; orientating the second portion toward the fiber surface, while orientating polymer to the side different from the surface of the first group; and forming a fiber absorber by heating the fiber having the reformed surface in the step of orientating polymer to thermally bond the contact points of fibers themselves. With this method of manufacture, it becomes possible to enhance the uniform property of the fiber aggregate still more, which is formed subsequent to making the property of such fiber aggregate uniform per unit of single fiber or small aggregate existing in any one of stages before the formation thereof.

The present invention provides a manually operated projection screen having a decelerating and locking mechanism which intergrates a decelerating mechanism and a locking mechanism as a whole. The decelerating and locking mechanism for a projection screen includes a braking and locking device having a centrifugal brake shoe, a brake drum interacting with the centrifugal brake shoe to perform decelerating function, and a ratchet interacting with the centrifugal brake shoe to perform locking function. The decelerating and locking mechanism includes at least three sets of planetary gear, the transmission ratio of the planetary gear is 1:32 or above. The decelerating and locking mechanism and the projection screen using the same is compact and easy to assemble. The projection screen can be freely positioned or locked at any moment and is free of crease.

A terminal structure of a chip-like electric component capable of blocking entry of electromigration-causing factors through an insulating resin layer in the vicinity of the peak of a raised portion of an electrical element forming layer is obtained. A metal-glaze-based front electrode 103 containing silver is provided on a surface of an insulating ceramic substrate 101. A resistor layer 107 electrically connected to the front electrode 103 is provided on the substrate surface. A glass layer 109a is provided to completely cover a surface of the resistor layer 107 as well as a surface of an end portion of the resistor layer 107 and also to partially cover the front electrode 103. An insulating resin layer 109b is provided to cover a surface of the glass layer 109a as well as a surface of at least an end portion of the glass layer 109a and to partially cover the front electrode 103. A conductive layer 117 made of a resin-based conductive paint is provided to extend over the surface of the front electrode 103 and an portion of the insulating resin layer 109b in the vicinity of the peak of raised end portion of the insulating resin layer 109b. The resin-based conductive paint is made by kneading particulate conductive silver powder and scale-like conductive silver powder into an epoxy-based insulating resin paint.

The apparatus is a 28 speed, two section, transmission that requires only a single clutch swap for most changeovers between adjacent ratios. It uses a first section with three close ratio forward speeds and one reverse along with a second section that is an 11 speed, wide ratio, transmission. The two transmission sections are arranged in series resulting at least 28 usable forward speeds. The second section includes an intermediate planetary gear set without a ring gear and an output planetary gear set that is a conventional simple planetary gear set with a two sun gears, two planes of planetary gears on a single carrier, and two ring gears.

An antiferromagnetic stabilization scheme is employed in a magnetic head for magnetically stabilizing a free layer of a spin valve. This is accomplished by utilizing an antiferromagnetic oxide film below a spin valve sensor in a read region and first and second lead layers in end regions and a ferromagnetic film in each of the lead layers that exchange couples to the antiferromagnetic oxide film in the end regions. The ferromagnetic films are pinned with their magnetic moments oriented parallel to an air bearing surface (ABS) of the magnetic head. The ferromagnetic film magnetostatically couples to the free layer which causes the free layer to be in a single magnetic domain state. Accordingly, when the free layer is subjected to magnetic incursions from a rotating disk in a disk drive, the free layer maintains a stable magnetic condition so that resistance changes of the free layer are not altered by differing magnetic conditions of the free layer.

A light emitting diode drive device includes a drive circuit section that applies a direct-current voltage to a light source including a plurality of light emitting diodes connected in series to allow the light source to light up, a voltage detection circuit section that detects a voltage across the light source, and a malfunction determination circuit section that determines that the light emitting diode is short-circuited when the voltage detection circuit section detects a voltage drop and a potential between the voltage before being dropped and the voltage after being dropped is equal to or more than a predetermined threshold value. Thus, it is possible to detect a fact that a light emitting diode, which lights up, is short-circuited or is not short-circuited, with a simple circuit configuration.
