Title: Manufacture of inlaid tile
Inventor: HASHIMOTO YOKICHI
IPC: B44C1/20
Filed: 1989-03-15
Abstract: PURPOSE:To make inlaid pattern clear by a method wherein a base tile is pre-pressure-formed by pressurizing force, by which shape is almost retained, and, at the sametime, recesses are produced and inlaying pellets, which are produced by pre-pressure-forming body with different color, are fittingly installed in the recesses and, finally, the whole body is pressure- formed. CONSTITUTION:Ground color body 18 is filled in a forming space 17, which is produced by a frame force 15 and a bottom force 16. Solenoids 12, which correspond to molds 13 taking charge of regions surrounded by circles (p)-(w), of a top force 10 are turned ON so as to project the molds 13 belonging to the circles (p)-(w) beyond the forming surfaces of the molds 13 belonging to the other region than the regions surrounded by the circles (p)-(w). Under the above-mentioned state, the top force 10 is lowered so as to pre-pressure-form a base tile 19 by pressurizing force, by which shape is almost retained in order to form the base tile, in which parts corresponding to the regions surrounded by the circles (p)-(w) are formed in recesses 20 and 21. Next, inlaying pellets 22, 23 or the like, which are produced by pre- pressure-forming body with desired different color by the same pressurizing force as that applied to the base tile 19, are fittingly installed in the respective recesses 20 and 21. After that, all the solenoids 12 are turned OFF so as to bring all the forming surfaces of the top force 10 into the same level surface. Finally, the top force 10 is lowered so as to uniformly pressure-form the whole body regularly.

Title: Message transmitting method for tdma communication system
Inventor: KAHN COLIN LEON
IPC: H04B7/24
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To transmit comfortable noise during a mute period and to precisely measure interference in allocating a channel to a new call by continuing a step for substituting a long message in a time slot for an abbreviated message. SOLUTION: When the time slots 1 and 2 do not transmit the message in the mute period, 324 bits associated with the slots are transmitted. When a communication channel in a time slot 3 is in the mute period, slight information of 80 bits is transmitted during the time slot. It is shown by the area 60 of the respective time slots 3. Thus, the slight part of the time slot 3 is used for actual transmission and transmission is not executed in a remaining part. Thus, power is reduced and common channel interference is reduced. The width of an area 60 can be increased/decreased by transmitting much more bits or transmitting few bits.
