IPC: C02F1/44
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To lessen the deterioration of a high polymer porous membrane and to reuse filtered water when treating CPM waste water using the high polymer porous membrane filter by decomposing hydrogen peroxide in waste water in advance and feeding the waste water to the filter. SOLUTION: From a chemical/mechanical polishing (CPM) device 1, CPM waste water containing hydrogen peroxide and alumina abrasive grains is discharged to a pretreating tank 2. NaOH aqueous solution in a neutralizer tank 3 is injected by an injection pump 8 and hydrogen peroxide decomposing enzyme in a hydrogen peroxide decomposing agent tank 4 is injected by a fixed delivery injection pump 9, and the mixture is agitated by an agitator 6. The treated liquid in which hydrogen peroxide is thus decomposed in the pretreatment tank 2 is transferred to a circulation tank through liquid transfer piping 11 by a liquid transfer pump 10, and enters a high polymer membrane through a circulating pump, and is separated into filtrate and concentrate there. The filtrate is used as washing water through an ion exchange tower.

Title: Voice information transmitting method
Inventor: YAMAGUCHI MIKIO
IPC: H04H20/00
Filed: 1985-12-13
Abstract: PURPOSE:To transmit many pieces of voice information to a receiver with limited information sending capacity (e.g., frequency band) by selecting and storing required information signal at a reception section and converting the information code of the stored information signal into voice as required. CONSTITUTION:A digital information signal (a) comprising a classification code and an information code is sent from a transmission section 1 via a transmission line 2. On the other hand, a reception section 3 has a selector 4 comprising a CPU, a storage device 5 comprising a semiconductor memory and a floppy disc and a voice rule synthesizer 6. The meaning of the classification code is determined in advance. Each reception section 3 uses the selector 4 to register only the required classification code in advance. The selector 4 compares sequentially the registered classification code with a classification code of an information signal sent one after another. Only the information signal whose classification code is coincident with the registered code is selected and stored in the storage device 5. When a command is given from a recipient, the voice rule synthesizer 6 forms a text from the stored information code and outputs it as voice. The reception section obtains only voice information registered in advance among various pieces of information such as stock dealing market, traffic information and weather forecast.

Filed: 1985-12-17
Abstract: PURPOSE:To provide centering function of a band shaped body to sheet passing equipment, by providing magnets to both sides of the band shaped body, in an equipment for floating and travelling the band shaped body of magnetic material. CONSTITUTION:One or more electromagnets 10A, 10B or permanent magnet are arranged to both sides of the metal band shaped body 1 being magnetic material and travelling on gas floating and supporting apparatus contg. many arranged floaters 4A, 4B so that these are not contacted with the body 1. The magnet 10 is composed of yokes 12 having several teeth made of magnetic metal material and coils 11 wound surrounding circumference of tooth. Now, in case the body 1 is moved to plus side (the magnet 10B) in X (band shaped body width) direction from center position of the yoke 12, a force Fx is increased and decreased at the magnets 10A, 10B sides respectively and the force to return the body 1 to negative side is caused. Consequently if the force of magnet is held stronger than the force for moving the body, movement thereof is prevented. The band shaped body is pulled to magnet by a force Fy in Y (up- and-down) direction, but it is balanced by floating force of the floater 4.

Title: Processor and method for speech signal processing and device and method for expanding voice bandwidth
Inventor: OMORI SHIRO
IPC: G10L21/0388
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To clearly reproduce a fricative and an affricate when voice bandwidth is expanded by LPC synthesis. SOLUTION: An input voice signal is analyzed by an LPC analytic filter 2 to retrieve the most matching autocorrelation as a parameter from a narrow- band code book 6, the parameter corresponding to it is outputted from a broadband code book 12, and an LPC synthesizing filter 11 performs synthesis. Consequently, the bandwidth of a voice is expanded. An affricate detecting circuit 7 detects a fricative and an affricate by using the autocorrelation value of the input voice signal and the value of frame power. Once the fricative or affricate is detected, the whole or part of the band of an exciting source is boosted. Consequently, a power deficiency in case of the fricative or affricate is improved to clearly reproduce the fricative and affricate.
