Title: Information carrier disk scanner
Inventor: NORUBAATO HAINRITSUHI
IPC: G11B21/08
Filed: 1990-02-02
Abstract: PURPOSE: To increase the reduction gear ratio of a gear mechanism which drives a scanning device and to reduce the total volume of the gear mechanism by installing another driving member in coaxial connection with the shaft of the worm wheel and a spiral ridge for driving the gear rack in this member. CONSTITUTION: The shaft 23 of the worm wheel 21 is tilted toward the face of the disk 2 and another driving member 22 in coaxial connection with the worm wheel 21 is installed. This driving member 22 is composed from a supporting member 27 having a conical surface 26 and this member 27 is provided with at least one spiral ridge 28 for driving the gear rack 16 whose sectional shape is made to correspond to the geometric shape of the flank of the gear rack 16. Therefore even when the reduction gear ratio of the worm wheel itself is small, the total reduction ratio of the gear mechanism is made faily large by its combination with a large reduction ratio obtainable by the spiral ridge 28, ensuring high-precision transfer of the scanning device. By this, the gear mechanism 18 is made small-sized and a large overall reduction ratio is obtained.

Filed: 1989-01-31
Abstract: PURPOSE:To exhibit the excellent sound absorption properties by pressing a compound in the specified conditions which consists of slag having specified size, thermosetting powdery resin and kerosine and has the specified rate thereof, heating and molding this pressed compound. CONSTITUTION:This sound absorbing material is obtained by pressing a mixture of by weight 80-98% slag particle 1 crushed to 1-5mm<3> size, 1.5-15% thermosetting powdery resin 2 and 0.2-2.0% kerosine at 15-50kg/cm<2> pressurizing force in 5-15sec pressurizing time and heating this pressed mixture at 150-350 deg.C and molding it. Slag itself is porous and also many spaces 3 are present between the particles 1 and therefore this sound absorbing material exhibits the excellent sound absorption properties. Further mechanical strength is enhanced by molding this sound absorbing material into a plate and interposing a wire gauze to the intermediate part. When size of the particle 1 is less than 1mm<3>, porosity is impaired. The appearance is impaired in the size not less than 5mm<3>. The quantities of resin 2 and kerosine are preferably regulated to the above- mentioned range from the viewpoint of function and cost.

Title: Pulverized coal burner
Inventor: DEWA KOU
IPC: F23D1/00
Filed: 1980-02-25
Abstract: PURPOSE: To minimize production of NOx and to raise the combustion efficiency, by forming a flame holder at the top of a primary throat in a unitary manner, disposing a secondary throat on the outside of the primary throat in a freely retractable manner, and forming a burner throat in the form of a diffuser.  
     CONSTITUTION: An outwardly enlarged flame holder 7 is formed at the top of a primary throat 1 in a unitary manner, and a secondary throat 3 for feeding secondary air is disposed on the outside of the primary throat 1 concentrically therewith and in a freely retractable manner. Further, a burner throat 4' for feeding tertiary air is disposed on the outside of the secondary throat 3. Here, the burner throat 4' is shaped in the form of a diffuser. With such an arrangement, it is enabled to restrict mixing of pulverized coal with secondary and tertiary air, so that the pulverized coal is combusted by primary air slowly and at a low temperature. Here, because of shortage of O 2  in primary flame 5, production of NOx can be minimized. Further, production of CO and uncombusted carbon can be also minimized since the combustion efficiency can be raised by the diffuse combustion.
