Title: Condensation of sludge by gravity
Inventor: YAMAZAKI HARUYOSHI
IPC: B01D21/01
Filed: 1990-09-19
Abstract: PURPOSE:To condense a sludge in a stability and in a high concentration by passing a dinitrogen oxide through a developing sludge and condensing the so processed sludge for separation in a gravity type condensation tank. CONSTITUTION:A redundant sludge 1 is extracted from water treatment facilities and, to prevent the putrefaction thereof, introduced into a sludge aeration tank 2 wherein a dinitrogen oxide 3 is blown thereinto and the aerated sludge 4 is transferred to a gravity type condensation tank 5. In this tank, the sludge is condensed in a high concentration, discharging a condensate liquid 6. On the other hand, in the sludge aeration tank 2, the condensability is improved due to the effects achieved by degassing and decarboxylation of gases adsorbed into the sludge (N2 . CO2 . CH4) and the inhibition of putrefaction incidental to the solubilization of dinitrogen oxide.

Abstract: PURPOSE:To avoid electrode discontinuity and the short circuit of a junction by a method wherein, after the corners of the bottom of an aperture formed in an insulating film on a semiconductor substrate are covered with high melting point metal silicide layers, high melting point metal is selectively made to grow. CONSTITUTION:An aperture 4 is formed in an Si oxide film 3 to form an electrode in an N-type region 2 formed in the surface of an Si substrate 1. Then tungsten silicide 5 is applied to the surface of the substrate 1 and the silicide 5 is removed by anisotropic etching except the silicide 5a remaining on the corners of the bottom of the aperture 4. Then tungsten is selectively made to grow to fill the aperture 4. Then an Al electrode 7 is formed on the surface and patterned. With this constitution, the unevenness of the electrode 7 on the surface can be small so that good flatness can be obtained and the discontinuity of the electrode 7 can be avoided. Moreover, as the erosion of Si under the film 3 during the selective growth of tungsten is prevented by the silicide 5a, defects such as the short circuit of a junction can be avoided.

Filed: 1984-11-28
Abstract: PURPOSE:To evade a variation in the frequency of an impulsive high light output by converting laser light in a weak oscillation state into high-output pulse light at timing where a sweep frequency coincides with a specific value. CONSTITUTION:A manual switch SW0 in a detecting circuit 100c is upset to the side of a contact a-2. Then, the output of the clock generator 4 is inputted to the X terminal of an up/down counter 5 when an electronic switch SWE is upset to the side of a contact a-1 previously. Then, a counter 5 counts clock pulses and its output is applied to a D/A converter 3 successively, so a voltage developed at a terminal 122 as an analog value is a staircase wave downward voltage. Further, a carry signal is outputted from the terminal C of the counter 5 with the lapse of time and applied to the switch SWE. Then, the switch SWE is switched from the contact a-1 to a contact b-1 to generate a staircase upward voltage, and repeats this operation many times. When the number of bits of the counter 5 is large, the step of the staircase wave is small enough to ignore.

Abstract: PURPOSE:To suppress the deterioration of vibration proof rubber and to make the life thereof long by providing the vibration proof rubber which is sandwiched between a supporting member and a disk driving mechanism being situated at an ascending position and an energizing means which energizes the disk driving mechanism in the ascending position side. CONSTITUTION:When the CD driving mechanism 3 arrives at the most ascending position, a washer 21 and the vibration proof rubber 20 abut on an E ring 22. As the result, a spring for chucking 18 is elongated. Then, under the state the vibration proof rubber is deformed a little, the CD driving mechanism 3 holding a CD 2 between a clamp member 27 and itself becomes independent from a chassis 1 and the like, floats and has vibration proof ability. Besides, when the CD driving mechanism 3 is at a descending position, the unnecessary deformation of the vibration proof rubber 20 is avoided by deflecting only the spring for chucking 18. Thus, the life of the vibration proof rubber 20 can be made long.
