Title: Sludge treatment method and organic waste water treatment method including the method
Inventor: OTAKE HISAO
IPC: C02F3/30
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To separate and recover a phosphorus component efficiently in a short time by heating sludge at specific temp. for a specific time. SOLUTION: In a phosphorus discharge tank 3, sludge is heated at 60-90 deg.C for 10-120 min by a heating means 9 to discharge a phosphorus component in sludge to a liquid phase. When sludge is heated under this condition, the phosphorus component can be precipitated mainly as polyphosphoric acid. Whereupon, as compared with such a case that the phosphoric component is discharged as orthophosphoric acid or the like, the necessary amt. of a flocculant such as a metal salt or the like necessary for recovering the phosphorus component as a precipitate from a liquid phase is reduced. Since metal polyphosphate forms larger granular precipitated lumps as compared with metal phosphate, recovery treatment becomes easy. As a result, the phosphorus component contained in org. waste water can be separated and recovered in a small vol. liquid or solid state for a short time.

Abstract: PURPOSE:To contrive to bring the silicide layers, which are used as the masks for ion-implantation, into a low-resistance state and to reduce the wiring resistance by a method wherein the first and second heat treatments are both performed with the aim of crystallizing the silicide layers before and after the ion-implantation to be performed on the surface of the substrate. CONSTITUTION:A field insulating film 12 is formed on the surface of a P-type Si semiconductor substrate 10. Then, a gate insulating film 12A is formed on part of the surface of the substrate 10, which corresponds to the opening part of the film 12. After that, an MoSi2 film is deposited on the whole surface of the substrate 10, and a silicide layer 14 for gate electrode and a silicide layer 16 for wiring are formed by performing a patterning. Then, the layers 14 and 16 are crystallized from the amorphous state by performing the first heat treatment. Then, an N-type decision impurity is selectively ion-implanted in the surface of the substrate 10 using the silicide layers 14 and 16 as masks. By this implantation, the sheet resistivity of the MoSi2 film becomes considerably higher. Then, the silicide layers 14 and 16 are crystallized from the amorphous state by performing the second heat treatment. By this heat treatment, the resistances of the layers 14 and 16 are made lower than the original sheet resistivity of the MoSi2 film. As a result, the wiring resistance is reduced and a higher-speed operation of this device can be contrived.

IPC: H01L21/68
Filed: 1985-05-27
Abstract: PURPOSE:To enable for an operator to identify wafers visually and to eliminate inputting of the identification information, by attaching prealignment marks including wafer identification marks to the respective wafers. CONSTITUTION:Information concerning a reticle 1 set in a semiconductor printing apparatus is stored in an internal memory 16. When the reticle 1 is set, the reticle information is fed to an alignment confirming circuit 18 from the internal memory 16. When the wafer identification apparatus 17 finishes the prealignment, it receives information of the prealignment marks 20 from the prealignment circuit and reads an array of black and white sections of the wafer identification mark 19. The wafer identification apparatus 17 reads the identification information of the wafer from the pulse width of the video signal wave form 24. In this way, it can be eliminated that an operator identifies visually the wafer to input the identification information, and thus the information inputting and the alignment-and-monitoring operation by the operator can be removed to attain the automation of wafer identification.

Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To display an URL(Uniform resource location) number corresponding to relating URL without largely changing the layout of original image information by inserting an index number to the position of the related partial character string information of HTML document information. SOLUTION: The index number uniquely corresponding only to the URL number appearing in the HTML document is inserted in the HTML document. Also, it is superimposed on partial image information and displayed and the correspondence relation of the index number and the URL number is displayed at the blank part of FAX image information. A digit number required for the index number can be the digit number sufficient for expressing the total number of the URL number to be inserted in the HTML document. By indirectly displaying the URL number by using the index number in such a manner, the digit number required for the index number is reduced and the distortion of the layout in the case of converting HTML document information to the FAX image information is minimized.

Title: Reduced-pressure computation apparatus for diving use
IPC: G01C13/00
Filed: 1992-04-03
Abstract: PURPOSE:To enhance the safety of a diving operation by a method wherein the breathing/ discharge coefficient of an inert gas by a breathing operation is stored and the partial pressure of the inert gas inside an actual tissue is computed accurately on the basis of the coefficient. CONSTITUTION:When a safety coefficient K is input through a switch part 20 in a diving operation, the coefficient is written into a RAM 16 only when it is within a prescribed range. When the diving operation is started, water-pressure data which has been detected by means of a water-pressure sensor 17 is input to a CPU 14, and the CPU 14 computes the nitrogen partial pressure of a breathing gas and the depth of water. It is judged whether a floating operation is to take place or not. The half-saturation time to be stored in a ROM 15 is set when the floating operation is not to take place. The nitrogen partial pressure inside a body is computed at each tissue part of a human body. It is compared with a maximum permissible safety limit amount stored in the ROM 15. When the partial pressure is smaller than the limit amount, the nonreduced-pressure diving time is computed. In the floating operation, a value in which the half-saturation time has been divided by the safety coefficient is set as the half-saturation time and the nitrogen partial pressure inside the body is computed. Since the partial pressure of an inert gas inside the tissue of the human body can be computed accurately in this manner, the safety of the diving operation can be enhanced.

Title: Loudspeaker telephone set
Inventor: FUJISAKI HISASHI
IPC: H04M1/60
Filed: 1986-05-16
Abstract: PURPOSE:To prevent the echo cancelling from being affected even if many distortion is caused from a speaker amplifier due to the increase in an input signal level by providing a means obtaining an input signal of a pseudo echo generating circuit from an output signal of the speaker amplifier. CONSTITUTION:In a loudspeaker telephone set provided with an echo canceller cancelling an echo signal produced from an acoustic signal outputted from a speaker from the acoustic signal inputted to a microphone, a pseudo echo generating circuit 4 is inserted between the output side of a speaker amplifier 2 and a substraction circuit 5 and the input signal of the circuit 4 is obtained from the output signal of the speaker amplifier 2. Since the pseudo echo is generated from the output of the speaker amplifier 2 having the possibility producing the largest nonlinear distortion in this way, even if the input signal level is increased and much distortion is caused by the speaker amplifier, the sending of noise due to the distortion is avoided to the opposite party without giving effect on the echo cancelling.
