Abstract: PURPOSE:To make effective operation and provide a high rate of service time by furnishing a load absorbing buffer for temporarily accommodating a printed board units overflowed from the line, and treating the test load dispersedly with a plurality of testing machines. CONSTITUTION:A printed board unit 1 is carried onto a jig 2 by a transporting mechanism. At this time, bar-code to show the sort of item is read by a BCR 4, and if the type is such as to allow testing by this testing machine, a vacuum pump 5 is driven, and the unit 1 is attracted on and held by the jig 2. This generates contacting of a certain specific point on the unit 1 with a test probe, and it is possible to take out signal to the by 3 of testing machine. In this condition, the unit 1 is tested. When the test is completed, the pump 5 is stopped, and the unit 1 is released and carried out. If the test result at this time is 'fail', a control of exhausting the unit to a failed unit stocker 6 is executed, and if 'pass', the unit is exhausted from an exhaust lifter 11 via an acceptable unit path.

Title: Light-emitting diode array
Inventor: SUGAWARA SATORU
IPC: H01L27/15
Filed: 1993-02-18
Abstract: PURPOSE:To provide a high-density light-emitting diode array, which could not be realized in the past, by protecting a light-emitting part from chippings, even if the length from the light-emitting part of a light-emitting diode array to the end of a chip is made smaller than the size of a chipping.

Title: Printing plate material and its regenerating method
Inventor: SUDA YASUHARU
IPC: B41N1/14
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To manufacture a printing plate material to be regenerated while being in compliance with the digitization of printing process and also provide a regenerating method thereof. SOLUTION: A structure of forming a coated layer containing a zinc oxide photocatalyst formed on a base is utilized as a printing plate material. In the initial state of manufacture of the plate, the coated layer surface is adjusted into the state of demonstrating hydrophobic properties. Rays (ultraviolet rays) with the wavelength of energy higher than the band gap energy of the zinc oxide photocatalyst are emitted on the surface to covert a part of the surface into a surface demonstrating hydrophilic properties. The conversion is carried out based on a digital data for an image to be printed. A hydrophobic section is utilized as an image area while a hydrophilic section is utilized as a non- image area by the arrangement.  When the printing is completed, the emission of energy bundles or the formation treatment is applied in the composite state or alone to convert again the whole of the coated layer surface to the initial state of the hydrophobic properties demonstrated in the manufacture of the plate.

Title: Aluminum alloy
Inventor: TAKAI TOSHIHIRO
IPC: C22C21/06
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To improve the extrudability and surface appearance of an alloy by prescribing elements to be incorporated into an Al alloy. SOLUTION: This Al alloy contains, by weight, 0.40 to 0.48% Si, 0.45 to 0.55% Mg, <=0.25% Fe and 0.01 to 0.10% Cr. The reason why these elements are added thereto is as follows. Namely, Si and Mg contribute to the improvement of its strength. Fe conceals fine defects (such as flaws) in the surface of the extruded material after anodizing. Cr refines the alloy crystal grains and precipitates compounds such as Mg2 Si precipitated into the Al alloy as a petaled shape. By this microscopic structural improvement, the extrudability (such as deformation resistance and surface appearance) of the Al alloy is improved. Furthermore, by adding prescribed amounts of Mn and Cu as well, the above effect can moreover be increased.

IPC: H01J29/90
Filed: 1991-02-25
Abstract: PURPOSE:To improve welding workability of spacer leads and round leads so as to prevent any shift of the welding position by making the width of the joint part between each spacer lead and each round rod lead wider than that of a leading out part of a vacuum container.

The welding workability is improved by making the width of the joint part between the leads 1 and the leads 2 wider than that of leading out part of the vacuum container and thus any position shift of the leads 2 can be absotbed. Consequently, the welding workability of the leads 1 and the leads 2 is improved and the leads 2 are prevented from shiffing of their positions.

Title: Optical salt deposition detecting sensor and salt deposition measuring instrument using said sensor
Inventor: MIYATA YASUHIRO
IPC: G01N21/41
Filed: 1989-02-10
Abstract: PURPOSE:To easily discriminate salt deposition by using an optical waveguide having a refractive index lower than that of KaCl and an optical waveguide having a higher refractive index and detecting the difference in the variations of light loss between both waveguides. CONSTITUTION:The sensor part 12 is formed by a first optical waveguide 1 and a second optical waveguide 2. When the light from a light source 8 is made to enter from one ends of the waveguides 1 and 2, the transmitted light reaches the other ends of the waveguides 1 and 2 almost without any loss, since both waveguides are surrounded by air. When salt particles deposit on the waveguide surface, light loss is caused in the waveguide 1 having the refractive index lower than that of NaCl, however light loss is not caused in the waveguide 2 having the refractive index higher than that of NaCl. In addition, since a third optical waveguide 16 is covered with a low-refractive-index resin around the waveguide 16, light loss is not caused even if salt is deposited. As a result, the salt deposition can be detected irrespective of a disturbance by measuring the difference in the relative variations of the light loss between the waveguides 1 and 2 with the light loss of the waveguide 16 as a reference.

A multicolor toner image obtained thus is uniformly irradiated with a transfer pre-exposure lamp 30 if necessary and transferred on a transfer paper P with the aid of a transfer pole 33. After separating the transfer paper P from the photosensitive body 1, the image is fixed by a fixing device 31. Thus, the high-quality multicolor image is stably formed with excellent transferring ability and cleaning ability.
