IPC: H04N7/173
Filed: 1995-02-28
Abstract: PURPOSE: To provide a communication type information providing system capable of reporting that information is not distributed yet even though charging is performed and executing the redistribution of the information. CONSTITUTION: A KARAOKE terminal 10 transmits the distribution request of desired music to a charging center 30 and the charging center 30 transmits charging information constituted of a code for indicating corresponding music data and charging information ID through a videotex communication network to the KARAOKE terminal 10. Thus, a charging processing is performed and a result is transferred from the charging center 30 through a public line 50 to an information center 20. The information center 20 distributes the music data completed with charging to the KARAOKE terminal 10 based on the result, however, when it is detected that the distribution of the music data is not performed within the fixed period of time in the KARAOKE terminal 10, music data undistribution notice and purchased charging information are transmitted to the information center 20.  The information center 20 distributes the corresponding music data to the KARAOKE terminal 10 after confirming that it is the correct charging information ID.

Title: Conveyor for electric part
Inventor: CHIBA MINORU
IPC: B65G21/22
Filed: 1983-03-14
Abstract: PURPOSE:To remarkably enhance the efficiency in electric parts manufacturing by conveying electric parts such as cylindrical chip parts in such a manner that the parts can undergo painting process, in cooperation of an endless belt with through-holes perforated at a specified pitch, rails underneath the belt, and conveyor equipment installed between the rails. CONSTITUTION:A belt 1 made up of stainless steel is provided, along its center line, with through-holes 1a arranged orderly at specified pitch p. The size of the through-hole 1a is determined in such a manner that its width is a little greater than the length of a cylindrical chip part and its length is L2 (long) at its middle part and L1 (short) at its both sides. When a part X is situated over a rail 4, it is supported by the rail 4. However, since it cannot be supported at a joint-space between the rails 4, a magnet 41 is provided over the belt 1 at the place corresponding to the joint space. By the magnetic absorbing force, the magnet 41 lifts up the part X, conveys it in the direction of the travel of the belt 1, and hands it over the subsequent rail 4. A demagnetizer 42 is installed on a connecting part between the magnet 41 and the subsequent rail 4 to eliminate the magnetization caused by the magnet 41.

Title: Device for separating liquid
Inventor: YAMAMOTO FUSHIJI
IPC: B01D3/00
Filed: 1989-02-21
Abstract: PURPOSE:To facilitate the control and operation of a device and to separate and recover liquid efficiently by causing liquid in a storage tank to flow under its own weight through a water separation filter to a distilling device and causing further the liquid having been distilled thereby to flow under its own weight through a U-tube into the storage tank. CONSTITUTION:Liquid in a storage tank 13 flows under its own weight through a water separation filter 16, whereby water contained in the liquid is separated and discharge from a discharge pipe 16a, while the liquid having passed through the filter 16 is collected in an evaporator 31, where the liquid is heated by a heater 32. The vapor of low boiling point thus vaporized flows upwardly through a column 33 into a condenser 34 to be condensed into liquid of low boiling point, which liquid flows under its own weight through a U tube 18 into the tank 13, wherein the U-tube 18 causes an increment in vapor pressure in a condensing chamber 34a, whereby the condensation of low-boiling-point liquid is effected nearly completely, while entrainment and vaporization of high-boiling-point liquid is restrained. At the end of distillation, only low-boiling- point liquid of high purity is collected in the storage tank 13 and high-boiling- point liquid of high concentration is stored in the evaporator 31.

Abstract: PROBLEM TO BE SOLVED: To make a compd. semiconductor layer thin and form a good pn junction by depositing an n<+> -, n<-> , p<-> and p<+> -cadmium telluride films on a silicon crystal wafer having a pn junction near the surface. SOLUTION: A Si crystal wafer is composed of an n<+> -Si 1, n-Si 2 and p<+> -Si 3. An n<+> -, n-, p- and p<+> -CdTe films 4, 5, 6, 7 are deposited on the wafer. Since the dislocation and the crystal grain boundary of CaTe or ZnCdTe are electrically inactive, the pn junction characteristic is not deteriorated but a high photovolatic power generation efficiency can be held at a high level even if the defect exists at a high density in the pn junction. As the result there is no need of forming the pn junction of the CdTe photovaltaic generator unit to form a dual system with a Si photovoltaic generator unit at a position apart from a CdTe/Si hetero interface and it can be made thin.
