IPC: F28F9/26
Filed: 2001-11-21
Abstract: <P>PROBLEM TO BE SOLVED: To reduce heat transfer from a heat exchanger to a liquid receiver and to maintain a vibration-resistant strength of a coupling part.  <P>SOLUTION: Partition walls 11 and 12 are arranged in an intermediate portion and a lower end side portion of one header pipe 1 to form a first passage, a second passage and a third passage in a heat exchanger body 10, and a coupling member 5 for coupling the header pipe 1 with a liquid receiver body 20 is joined to a common region of the second and third passages in the header pipe 1. A relation between a joining area A of the header pipe 1 and the coupling member 5, and moment M acting on unjoined portions of the receiver body is set to be A/M>0.07. This reduces heat transfer from the heat exchanger body 10 to the receiver body 20 and maintains a vibration-resistant strength of the coupling part.  <P>COPYRIGHT: (C)2003,JPO

Title: Adsorbent and method for adsorbing pollutant
Inventor: KAWASHIMA ISAMU
IPC: B01J20/02
Filed: 2001-12-04
Abstract: PROBLEM TO BE SOLVED: To provide an adsorbent and a method for adsorbing pollutants which are widely applicable to any of air, water, and soil, have a high effect of adsorptively removing chemicals, odors, heavy metals, oils, or the like, and still has retentivity of that effect. SOLUTION: When an adsorptive bamboo charcoal is pulverized into a 5 μm or smaller powder, the resultant powder can attain an effective surface area about 250 times larger than that of a bamboo charcoal powder having a relatively large particle diameter, say, about 325 mesh, and therefore can exhibit sufficient adsorptive effect even when used in a small amount. Another advantage brought about by the pulverization is the capability of being used by mixing with or infiltration into raw materials for building materials, fibers, paper products, etc., as well as by methods such as placing, burying, and laying. The bamboo charcoal can not only exhibit an action of decontaminating water or soil in virtue of the above adsorptivity but also can bring about an action of microbially decomposing organic matter in, e.g. water by forming a curtain of microbes on the surface of its inside.  The latter action, though not quick, can persist for a long term.

Title: Disk player
Inventor: UEHARA KENJI
IPC: G11B7/12
Filed: 2001-12-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a disk player which can grasp the suitable state of an optical pickup by reflecting a use condition.  <P>SOLUTION: When a reproduction operation begins, a timer 50 implements a timer operation. A temperature detecting part 28 measures the ambient temperature of the optical pickup 16. When the measurement time by the timer 50 exceeds a specific time, a damage index calculation part 52 calculates a damage index by multiplying a predetermined temperature coefficient corresponding to the ambient temperature of the optical pickup 16 by the operating time of the optical pickup 16 for updating the cumulative value, and stores the resultant value into a memory 32. A base temperature setting part 56 makes a reference temperature lower than a current value when the cumulative value of the damage index is compared with a prescribed reference value and the cumulative value of the damage index exceeds the reference value. When the ambient temperature of the optical pickup 16 exceeds the reference temperature, a part 54 for determining the propriety of an operation determines that it is necessary to stop the output operation of the optical pickup 16.  <P>COPYRIGHT: (C)2003,JPO

IPC: G02B6/42
Filed: 2001-12-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and device for assembling an optical product.  <P>SOLUTION: While the gap quantity between an LD element 50 mounted on a 1st mount 52 and a wavelength converting element 54 mounted and fixed on a 2nd mount 56 is denoted as d0 and the gap quantity between the 1st mount 52 and 2nd mount 56 is denoted D1, they are united by applying an adhesive 62 to the gap between the 1st mount 52 and 2nd mount 56. Here, although the coupling efficiency is higher and higher as the gap quantity d0 between the LD element 50 and wavelength converting element 54 is smaller and smaller, and desirable, the yield possibly decreases since the gap quantity d0 decreases owing to shrinkage due to adhesive hardening and the LD element 50 and wavelength converting element 54 possibly abut against each other to break. For the purpose, the optical product which is high in yield and has high coupling efficiency can be assembled by setting the gap quantity d0 for a target gap quantity d1 so that d0=d1+αD1, where α is the volume shrinkage rate of the adhesive 62.  <P>COPYRIGHT: (C)2003,JPO
