Title: Output circuit of pulse encoder
Inventor: TSURUTA KATSUJI
IPC: G05B19/23
Filed: 1981-12-23
Abstract: PURPOSE:To deliver plural pieces of forward and backward revolution information in a cycle of an output pulse with a simple constitution, by latching with two steps the output of a pulse encoder to form an address and then reading out the forward and backward revolution information from a storage means. CONSTITUTION:The waveform is shaped for output pulses PA and PB of a pulse encoder which have a shift of phases and the phase relation reversed between the forward and backward revolutions of a wheel. These output pulses are processed by a double-stage latch circuits 13 and 16 as well as 14 and 17. The  addresses are formed with the outputs of these latch circuits, and an access is given to an ROM15. Therefore, for instance, the forward revolution information D1 of a high level is delivered in the case of an address excepting 1000 and synchronizes with a clock PC in response to 2-bit signals AD4, AD5, etc. which control the ROM15. Then plural pieces of forward revolution information are delivered up to 4 units, etc. in a cycle of the pulse PA. The same applies to the backward revolution information. In such a way, plural pieces of forward/backward revolution information are produced in a cycle of an output pulse of an encoder with a simple constitution of a reduced number of component parts. This improves the detecting resolution.

IPC: C04B33/34
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To manufacture a tile of natural stone touch with a split texture face at a low cost even when a small lot of it is manufactured, by glazing the surface of a tile green molded by dry pressing after driving a chisel into the side face of the green to be split to have the split texture face having acute edges and baking the glazed surface. SOLUTION: In a tile green for two-cavity molding with a dovetail groove formed on the first and the second surface by a dry press molding process, two pieces of the tile green 3 with a dovetail groove formed on the second surface of the green 3 having a split texture face 4 with acute edges are obtained by driving a chisel into the center part, in the thickness direction, of the blank for two-cavity molding. Next a glaze (b) is sprayed on the split texture face 4 of the green 3 from a nozzle (a) and the glazed green 3 is baked to obtain the split texture face tile. This tile is free from the exfoliation of loose particles as the surface is coated with the glaze (b) and also from the possibilities that the tile might hurt the skin or scathe the surface of an object when the former strongly hits or rubs the latter, because the acute edges are smoothed.  In addition, the tile hardly receives a dust settlement and can be easily cleaned even when the dust settles on it.
