Title: Protective circuit for multiple chopper device
Inventor: OKAMURA KOICHI
IPC: H02M3/155
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To reliably detect which one of chopper device has failed, in a multiple-chopper device in which the chopper devices are operated in parallel. SOLUTION: An AND operation of a logic signal, obtained by comparing with a comparator 13 a voltage detected with an insulating converter 11 from the output side of a first transistor 3, making up of a first chopper device with the voltage set value of a voltage setting element 12 and the drive signal of a second transistor making up of a second chopper device, is computed with an AND element 23. If the computation results of this AND operation changes continuously for a given period of time, a warning timer 14 determines that an abnormality has occurred and issues an alarm.  Also an operation-delay correcting timer 31 which delays time corresponding to the operation delay time of a second transistor 2 is added to a drive signal circuit 21 to cause the AND operation element 23 compute the AND operation of the output of the operation-delay correcting timer 31 and that of the comparator 13.

Title: Method of melting waste
Inventor: KAKIHARA NAOMICHI
IPC: F23G5/08
Filed: 1980-06-25
Abstract: PURPOSE:To suppress the generation of NOX in a method in which waste or the like is burned and melted in a high temperature furnace bed formed of carbonaceous combustible matter, by suitably controlling the loading amount of the waste or the like, the feeding of carbonaceous combustible matter and the feeding amount of an oxygen-containing gas. CONSTITUTION:In a cupola type melting furnace 1 is formed the high temperature furnace bed 2 made of carbonaceous combustible matter, and the waste or the partially treated waste and carbonaceous matter are fed in admixture or alternatively from a hopper 3 onto the high temperature furnace bed 2 by alternatively  opening dumpers 4a, 4b, so that a loaded layer 5 is formed on the furnace bed 2. In  this state, the oxygen-containing gas such as air is fed in a suitable amount into the furnace bed 2 via a lower twyer 6 to burn and melt the loaded layer 5. The melted product is taken out from a takeout channel 7, on the other hand the produced gas is after-burned at the upper part of the furnace with oxygen-containing gas such as air fed from a twyer 8, and thereafter it is discharged into the atmosphere via an exhaust duct 9, a dust removing cyclone 10, etc.

Title: Polarizing prism
Inventor: KAWADA MASARU
IPC: G02B5/30
Filed: 1990-03-31
Abstract: PURPOSE:To satisfy a widely permeable wavelength range and a video field angle at the same time by forming two triangular prisms and a flat plate of the same birefringent material and setting the directions of the optical axes of the triangular prisms and flat plate according to whether the material is negative crystal or positive crystal. CONSTITUTION:The two triangular prisms made of the birefringent material are joined together across the flat plate made of the same birefringent material. When the birefringent material is the negative crystal, the optical axes of the triangular prisms are set parallel to the optical axis and the optical axes of the flat plate is set perpendicularly to the optical axis. When the material is the positive crystal, the optical axes of the triangular prisms are set perpendicular to the optical axis and the optical axis of the flat plate is set parallel to the optical axis. Consequently, the polarizing prism can be used over a wide wavelength range and the wide field angle is obtained.

Title: Method and device for speaker collating
Inventor: BIN KATSUTAKE
IPC: G10L25/51
Filed: 1995-04-12
Abstract: PURPOSE: To improve the security of the system while using the system by making the system to be discriminated whether the inputted voice is the natural voice of a registered user or a recorded voice or a synthesized voice in the device which uses a text specifying type speaker collating method. CONSTITUTION: During a speaker registration, the device side arbitrarily decides two kinds of specified texts. Then, a code book corresponding to each text is produced for every speaker and is stored in a code book storage section 18. During a speaker collation, a user is asked to pronounce text voices corresponding to the two specified texts. Then, the features of the inputted voices corresponding to one of the specified text are quantized by the code book for every speaker corresponding to the texts. After that, distortion distance in the speaker is obtained and a relative threshold value, which represents whether it is a natural voice or not, is determined from the feature difference of two voices and the distance between the code books. Then, the in-speaker-distortion distance and the relative threshold value are compared by a comparison section 15.  If the distance is larger than the value above, it is judged to be other than a natural voice and the processing in the speaker collation section 16 is made prohibitive.

Title: Controlling method for arc welding machine using consumable electrode
Inventor: KOBAYASHI MAKOTO
IPC: B23K9/09
Filed: 1981-06-05
Abstract: PURPOSE:To reduce spatters without making a short circuit period long by increasing welding current sharply after the detection of a short circuit between base materials and a consumable electrode, and decreasing the welding current before the electric power necessary for arc generation is supplied. CONSTITUTION:The discrimination circuit from a short circuit arc discriminator 8 which discriminates the short circuiting between base materials 7 and a consumable electrode 6 is inputted to a driving circuit 9. The circuit 9 controls the on and off a power transistor 2 in accordance with said discrimination signal, and controls the on of the power transistor continuously. Therefore, when the short circuiting between the materials 7 and the electrode 6 is detected (time t1), the welding current is increased sharply by the TR2 until it attains a peak value I2, after which it is decreased. The welding current value I2 at the arc generation (time t2) is made lower than that in the prior art, whereby spatters are reduced. In the period T3 when the electric power necessary for arc generation is supplied, the value is made lower than that in the perior art by the sharp increase in the welding current. Even after the time t2, the welding current is increased so as to prevent the extension in the arc period T4.

Abstract: PURPOSE:To surely form a solder resist between pads even when an interval between adjacent pads is narrow and to prevent a solder bridge from being caused by a method wherein a wide part is formed in the halfway part of each solder resist formed between a plurality of pads formed on the surface of a base material. CONSTITUTION:A circle-shaped wide part 4a which is formed in a diameter of nearly the same size as a width between adjacent pads 3b is formed in nearly the center of a solder resist 4 formed between the pads 3b.

IPC: B05D1/28
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain a uniform and stable coating film without the turbulence of a coating liquid being generated even on high speed coating. SOLUTION: In a coating device, a continuously traveling web 4 is contacted with a coating liquid 3 in a liquid pool 6, and the coating liquid 3 is regulated by a doctor knife 2 to coat it on the web 4. In this case, near the doctor knife 2 in the liquid pool 3, a control plate 8 opposite to the web 4 is fitted. The flow in a flow control area A surrounded by the control plate 8, a bottom plate 6a of the liquid pool and the web 4 is made like a streamline flow. Since the typical dimension in the area A is reduced by the insertion of the control plate 8, turbulence is not generated even when the typical velocity in the area A is increased. That is, the critical coating speed at which turbulence is not generated is increased, and even on high speed coating, a uniform and stable coating film is obtained.
