Title: Device for purifying water quality
Inventor: TSUGE KAZUO
IPC: B01D35/027
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To find optimum purifying interval depending on the progress rate of clogging by detecting the position of an inside float changed correspondingly to the increase of negative pressure at the suction side of a pump, which is related to the clogging state of a filter. SOLUTION: The negative pressure of the suction side of the pump 33 for sucking water through a water collecting pipe 15 inserted in the inside of a filter cartridge 13 is increased when the filter cartridge is clogged. Then the water surface 10c in a pipe line 36b of a detecting pipe 36, one end part of which is communicated with the suction side of the pump 33 through an extending pipe 37 and another end part of which is opened above the surface of water, becomes lower than the water surface 10a of the outside of the detecting pipe 36. When the inside float 38 floating on the water surface 10c reaches a prescribed position deeper than the water surface 10a of outside of the detecting pipe 36 by the lowering of the water surface 10c in the pipe line 36b, a control means works to detect the position by a sensor 39 and to wash the filter cartridge 13 by a washing means 34.

Filed: 1987-11-27
Abstract: PURPOSE: To perform cooling efficiently while preventing unnecessary cooling by providing a controller performing forced cooling operation for a predetermined time upon function of a first switch interlocked with a first door and stopping forced cooling operation for a predetermined time upon function of a second switch interlocked with a second door. CONSTITUTION: When a door 14 is closed after it is opened and a delivering matter 20 is placed in a box 16, it is detected by a first switch 15 and a cooling controller 13 is operated forcibly.

Filed: 1994-12-05
Abstract: PURPOSE: To recover a platinum group metal at a high efficiency by supplying a solution containing a noble metal obtained from a waste catalyst to an electrotytic cell and electrolytically depositing the platinum group metal after reducing 3-valent iron. CONSTITUTION: The noble metal such as Pt, Pd or Rh carried in a catalyst layer is eluted in an acid solution by treating a used catelyst with hydrochloric acid or the like. The 3-valent iron is reduced to 2-valent by introducing the noble metal containing solution into a 1st fludized bed type electrolytic cell and electrolytically reducing it at a lower current density of (0.3-0.5A)/(carbon particle 1L) than that at the time of electrolytically depositing the platinum group metal. The solution is circulated and an electrolytic reduction treatment is performed until the ratio of Fe<3+> to Fe<2+> reaches 1:1 to 1:2, thereafter, the solution is introduced into a 2nd fluidized bed type electrolytic cell, and an electrolytic deposition treatment is performed at an optimum current density to deposite the platinum group metal on fluidized cathode carbon partiles.  As a result, the platinum group metal is effectively recovered from the waste catalyst.

Abstract: PURPOSE:To attain natural sound recording while suppressing the undesired voice of operator by providing an operator detection circuit detecting the presence of the operator and a gain control circuit attenuating the collected signal when the operator makes an utterance. CONSTITUTION:When the operator looks into the view finder for the photograph and makes utterance while photographing an object, the sound pressure exerted to an operator microphone 4 is greater than that exerted to the sound collection microphone 2. Thus, the fact that sound collection signal level detected by signal level detection circuit 50 and weighted by a weighting circuit 52 is smaller than the operator signal level detected by the operator signal level detection circuit 51 is detected by a comparator 53 and the result of decision is sent to the gain control circuit 6. The gain control circuit 6 throws a switch 61 to the position of terminal B to send the output of the microphone 2 to the output terminal 7 through an attenuator 60. When the operator makes an utterance in this way, the output signal of the sound collection microphone is outputted with attenuation.

Title: Double speed converter
Inventor: UEDA MITSUNORI
IPC: H04N7/01
Filed: 1987-11-30
Abstract: PURPOSE:To prevent line flicker and degradation of vertical resolution by applying double speed conversion to an RGB signal of interlace scanning because the information of the same scanning line is not subject to change in the unit of fields. CONSTITUTION:The RGB signal is converted into a double speed signal by a double speed conversion circuit 1 and its output is retarded by a time T/2 at a delay circuit 2. On the other hand, a field detection circuit 3 detects an even number field and an odd number field from the synchronizing signal and sends information to a changeover circuit 4. Then an output signal of the circuit 2 during the odd number field, that is, the information of the odd number field becomes a double speed RGB signal. Moreover, an output signal of the circuit 1 during the even number field, that is, the information of the even number field becomes a double speed RGB signal. Thus, the double speed RGB signal is a signal where the information of the even and odd number fields are identical. Then the RGB signal of interlace scanning is converted into a double speed signal where the information of the same scanning line of adjacent fields is identical.
