Title: Preparation of ceramic having uneven surface
Inventor: OGAWA YUKIO
IPC: C23D13/00
Filed: 1982-03-23
Abstract: PURPOSE:To prepare ceramic having an uneven surface, with safe operation, by applying the first coating layer containing an alkali metal fluoride and the second coating layer containing a reaction initiator to the surface of a ceramic substrate, and heating the substrate to generate hydrogen fluoride. CONSTITUTION:The first coating layer is formed on the necessary part of a ceramic substrate using an ink composition containing an alkali metal fluoride compound such as Na3AlF6, and the second coating layer is applied thereto using an ink composition containing a reaction initiator such as NaHSO4 capable of generating hydrogen fluoride by reacting with the alkali metal fluoride compound under heating. The coated substrate is heated at a proper temperature between about 300 deg.C and 800 deg.C to allow the reaction of the alkali metal fluoride compound with the reaction initiator and to generate hydrogen fluoride. The part of the ceramic substrate to which the first and the second coating layers are applied is corroded and made uneven thereby. After heating, the residue is washed and removed by conventional means.

Title: Luminaire metal fitting
Inventor: ADACHI YOSHIKAZU
IPC: F21V21/04
Filed: 1995-03-07
Abstract: PURPOSE: To improve workability and also surely fix a luminaire to a soft ceiling by forming the ceiling pressing part of the luminaire into width insertable in a through hole, and providing a locking spring for locking the ceiling pressing part to the edge of the through hole in a condition where the ceiling pressing part is contacted with the upper surface of a ceiling material. CONSTITUTION: A luminaire metal fitting has a connecting part 1, an inner side abutting part 2, a locking spring 3, and a ceiling pressing part 4. The metal fitting can make a locking part 13 form an attitude, wherein the part 13 can be along the outer surface of a main body 6, by penetrating the part 4 into a through hole 7 while putting outside an outer side locking part 13 through a loose fitting hole from the inner side of the metal fitting main body 6 and making an inner side abutting part 2a abut on the inner surface of the main body 6. The main body 6 is inserted into an embedding hole in this condition, and then the part 13 is protruded from the main body 6 to draw an extruding part 4 to make it abut on the upper surface of a ceiling board and also to lock a spring 3 to the edge part of the hole 7 of the body 6.  The body 6 can be attached to the ceiling material, because consequently, in a condition wherein the part 2 abuts on the inner surface of the main body 6, the spring 3 bites and locks the part 4 into the surface of the main body to the movement wherein the part 4 is beginning to move outward the upper surface of the ceiling material by the gravity of the main body 6.

Title: Loop controlling method for absorbing length difference between strips before being wound
Inventor: MATSUBARA SHIGEJI
IPC: B26D5/00
Filed: 1985-03-08
Abstract: PURPOSE:To wind a multi-strip piece of high quality by controlling balance of three energies-i.e., feed energy to the multi-strip piece given by a loop control roller, the winding kinetic energy for the multi-strip piece, and the own energy of the multi-strip piece-by the use of rotational speed of the loop control roller. CONSTITUTION:A steel sheet 10 is wound back from coil by a rewinder 11 and cut into a multi-strip piece by a slitter 12. This is induced by control rollers 1-3 constituting a loop control roller and wound by a winding machine 16 after passing a separator roller 4 at the outlet from a loop forming trough 13. Velocity factors for each control roller 1-3 are determined from the weight of material to be processed itself and the frictional coefficient of it with the rollers. When this forms a loop r1 between roller 3 and separator roller 4, a signal from sensor 14 is fed into a rotational speed controller of roller 2 so as to form a loop r2 between the rollers 2 and 3, and in the same manner a loop r3 is formed between the rollers 2 and 1 through the sensor 14, and this process should be repeated.

Title: Method of sealing grooved type flange
Inventor: TAKEUCHI YUKIO
IPC: F16L23/16
Filed: 1982-03-24
Abstract: PURPOSE:To obtain stability of long period and high reliability to grooved type flanges of various shapes, by casting liquid sealing material in the groove of the grooved type flange into which an annular bank of one of joint surfaces is fitted, and pressingly mating both joint surfaces after the sealing material is cured. CONSTITUTION:A circular bank 3 on one of flanges is abutted to a sealing material 7 which is made resilient in a groove 5, and then the opposite surfaces of both flanges are pressingly contacted together by fastening a bolt 6 so that sealing is obtained. Since the sealing material 7 is held in a thickness larger than the clearance between the top of the bank 3 and the bottom of the groove 5, the sealing material 7 is partly built up into the gaps each defined between one of the lateral walls of the circular bank 3 and the associated lateral wall of the groove 5 when both flanges are mated at their opposed contacting surfaces 8 in the condition of metal touch. Thereby, the surface pressure exerted to the outer surface of the resilient material 7 given with resiliency, is relaxed so that it is not subjected directly to rigid strain due to flange vibration, thereby liquid leakage due to pumping action may be prevented.

Abstract: PURPOSE:To enable to continuously manufacture the titled pipe by extrusion without generating die waste over a long period of time by a structure wherein organic macromolecular material skin layer is formed on a water crosslinkable polyolefin pipe main body. CONSTITUTION:A skin layer S consisting of organic macromolecular material P2 is formed on a pipe main body R consisting of water crosslinkable polyolefin P1 by extruding the water crosslinkable polyolefin P1 simultaneously with the organic macromolecular material P2, which prevents die waste from developing. Because at least when the water crosslinkable polyolefin P1C passes the tip of a forming die 5, the outer surface of P1 has been covered with the skin layer S consisting of the organic macromolecular material, which develops no die waste, the skin layer S prevents residual unsaturated silane compound or other compounding agent from separating out onto the outer surface at the tip of the forming die 5, resulting in preventing die waste from generating.
