Abstract: PURPOSE: To recover supernatant water and concd. sludge while securing a specified sludge concn. by settling the ready-mixed concrete sludge flowing in a thickener, sensing the sludge concn., recovering the supernatant water and switching the cleaning of the thickener to air blowing or vice versa. CONSTITUTION: A vertically slidable cleaning pipe 12 is furnished to an agitating shaft 1 placed in the center of a thickener and lifted up and down by a hoist 16. A solenoid valve 23 is opened at the same time that the cleaning pipe 12 is lowered to a specified position, hence air is ejected from a nozzle 24, and cleaning water is ejected from the nozzle 24 of the cleaning pipe 12 through a water feed hose 15 to be opened and closed by a solenoid valve 14. Further, a downward conical screw blade 5 is fixed to the lower part of the shaft 1, and concd. sludge is forcedly discharged while preventing the clogging with the sludge. Meanwhile, a hydrometer 9 is movably held by a ball tap support 20 and slid by a guide rod 21 fixed to the inner wall of the tank to detect the concn. of the supernatant water, and the supernatant water having a sp.gr. below a specified value is removed.

Title: Outline correcting device of video signal
Inventor: YOKOMIZO YOSHIKAZU
IPC: H04N5/208
Filed: 1979-11-07
Abstract: PURPOSE: To make it possible to perform outline correction of good symmetry, even if the video signal is changed rapidly, by providing synthesizing means such as a differentiating means, a delay means, and an adder.  
     CONSTITUTION: Input video signal (m) generated from CCD1 is applied to not only the first adder 3 but also differentiating circuit 2 to obtain primary differentiated signal (n). When this differentiated signal (n) and input video signal (m) are added in 3, synthesized waveform (o) is obtained, and outline correction in the left is completed. Next, differentiated signal (n) has the phase inverted by inverter 4 to obtain inversion differentiated waveform (p). Though the same signal as original input video signal (m) is obtained if inversion differentiated waveform (p) and synthsized waveform (o) are added, video signal (m) is delayed through delay circuit 5 to obtain delay signal (q), and this signal (q) and waveform (p) are added by the second adder 6, so that outline correction in the right is performed. Consequently, output (r) of the second adder 6 has been subjected to left and right outline correction.

Title: Dosimeter
Inventor: TANOUE TOSHIYA
IPC: G01T1/15
Filed: 1990-05-31
Abstract: PURPOSE:To accurately perform measurement even when pile-up phenomenon occurs by discriminating the output of a semiconductor radiation detector by a first comparator, and discriminating the fact that it exceeds a prescribed threshold value by a second comparator. CONSTITUTION:When radiant rays are made incident intermittently on the semiconductor radiation detector 2, one pulse is supplied to a counter 6 via the first comparator 5 and an OR circuit 17. In such a case, no compartive output is obtained from the second comparator 11 by setting the threshold level of a reference power source 12 higher than that of a reference power source 4. On the contrary, when the radiant rays are made incident successively to the detector 2 in a short time, the pile-up phenomenon occurs, and a signal can be obtained successively until the output of the detector 2 is lowered, and the output level can be increased. An obtained signal is extended by a monostable multivibrator 13 via the comparator 11, and the AND with a transmitter 16 is taken at an AND circuit 15, and it is supplied to the circuit 17, thereby, counting can be performed even when the pile-up phenomen occurs.

Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To measure an error rate of a communication channel without transmission of unecessary data or the like by comparing the contents of a synchronous word stored in advance with a transmitted synchronous word. SOLUTION: A synchronization detection circuit 1 detect the synchronization of a reception signal, the reception signal is demodulated by using the synchronization timing and part of the demodulated signal is inputted to a shaft register 3. Furthermore, a bit register 4 stores a binary code of the same content as a synchronous word sent in advance. When synchronization is established by the synchronization detection circuit 1, every time, the synchronous word is registered as a binary code in the shift register 3, the synchronous word is compared with the content of the bit register 4, the number of error bits is detected and fed to a threshold level discrimination circuit 6.  When the number of error bits for a prescribed time are prescribed numbers or over, the threshold level discrimination circuit 6 outputs the information to a control circuit, which selects a base station to be handed-over.

Filed: 1986-06-20
Abstract: PURPOSE:To obtain a compact and high-precision aligner by disposing a plane mirror between an excimer laser optical system, a lighting optical system and a reticle, thereby eliminating the conventional condenser lens. CONSTITUTION:Light from a KrF excimer laser light source 1 is shaped, uniformized, and expanded in the beam diameter by an integrator 2. A condenser lens 3 is disposed next to this, and the light is incident upon the pupil of a reducing projection lens 6. The light path is made vertical by a plane mirror 4 to transfer the pattern on a reticle 5 onto a wafer 7 through the lens 6. If the reflecting surface of the mirror 4 is coated with a multilayer film of a high-reflectance Al film and a dielectric film for improving the reflectance, a reflectance of more than 99% is obtained. With this arrangement, since the conventional condenser lens is omitted, a dimension l2 is substantially shortened, and with l2+l1 having become short, deviation of the optical axis O2 due to oscillation is controlled, which is advantageous for forming a submicron exposure pattern.

Abstract: PURPOSE:To eliminate the formation of an oxide layer on a regrown boundary and to improve its characteristics and reliability by inhibiting to introduce a regrown boundary to a section which becomes a current path and presenting the regrown boundary only on a section in which a current does not flow. CONSTITUTION:A first clad layer 3, an active layer 4, a second clad layer 5, a third clad layer 6 and a cap layer 7 are sequentially grown on a substrate 1, the layers 7, 6 are removed by etching except a stripe section, and a current block layer 9 and a cap layer 10 are regrown on the removed section. Since the section which becomes the current path is not removed by etching and regrown but the section which becomes the layer 9 is formed by regrowing, the regrown boundary is not introduced to the section which becomes the current path, but presented only in the section in which no current blows. Thus, an oxide layer is not formed on the regrown boundary, and an element having excellent reliability and characteristics can be obtained.
