Title: Displacement measuring apparatus
Inventor: ADACHI SATOSHI
IPC: G01D5/244
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To enhance a real-time property in an absolute displacement measuring apparatus. SOLUTION: An ABS sensor 1 outputs signals which indicate the coarse position and the fine position of a moving element with reference to a fixed element. The signals are processed respectively by a demodulation circuit 2 and a demodulation circuit 3. The signal which indicates the coarse position is processed by an ABS data computing part 4, and high-order-digit data DH for absolute-position data is generated. The signal which indicates the fine position is introduced to a PLL counting-pulse generation part 7 via a selector 5.  In the PLL counting-pulse generation part 7, a pulse signal PULSE which corresponds to the phase difference between a dense-scale phase signal CMP which is input and a reference signal CNT which is generated at the inside, and the phase of the reference signal CNT is controlled in such a way that the reference signal CNT at the inside follows the phase signal CMP, A counter 8 counts the phase signal PULSE so as to generate low-order-digit data indicating the fine position. The data DH and the data DL are synthesized by a microcomputer 9, and the absolute position data is found.

Title: Method of denitrifying waste water by use of a flow layer
Inventor: YUSHINA YOSHINORI
IPC: C02F3/34
Filed: 1977-10-04
Abstract: PURPOSE: To prevent coagulation of particles by stirring the lower part of a flow layer, to take out, from the upper part of the flow layer active particles together with a part of water under treatment and send them back to the flow layer after micro- organisms are removed from them, and thereby to operate biological denitrification more effectively.  
     CONSTITUTION: Unprocessed water containing nitorus or nitric compounds is drawn from supply intake 1 into a denitrification reaction tower and is brought into contact on dispersion plate 3 with flow layer 4 consisting of denitrifying-bacteria- attached active particles and is sujected to detrification reaction, and then the water under treatment is discharged from pipe 2. In the lower part of flow layer 4, coagulation of sedimentary particles is prevented by means of a stirrer 5. Active particles to which micro-organisms are attched excessively and which have low specific gravities are taken out together with water under treatment sent from pipe 7 provided in the upper part of the flow layer and are passed through pump 8, and thereby excessive micro-organisms are removed from the particles, and then the water is sent back to the reaction tank from pipe 6
