Title: Treatment of electrolytic waste acid in electrolytic oxidation treatment of aluminium plate and moldings
Inventor: ISHIKAWA AKIRA
IPC: C25D21/16
Filed: 1977-10-22
Abstract: PURPOSE: To recover aluminium sulfate by the procedure in which a part of waste water containing aluminium sulfate discharged from electrolytic bath is concentrated to crystallize aluminium sulfate and then the gelled aluminum sulfate sludge is reacted with the waste water.  
     CONSTITUTION: A part of electrolytic waste water sent from the electrolytic bath 12 to the waste acid tank 13 is supplied to the evaporation-concentration apparatus 14 to concentrate the waste water, and then supplied to the vaccum crystallizer 15 to crystallize aluminium sulfate. The aluminium sulfate so obtained is filtered by the separator 16 to recover filterate as recovered sulfuric acid which is in turn sent to the supplementary liquid tank 11 where its concentration is readjusted and the liquid is supplied to the electrolytic bath 12. On the other hand, the filter cake is sent to the filter cake tank 17, where it is mixed with the remainder of the electrolytic waste water and then supplied to the aluminium sulfate manufacturing apparatus 18. Then, it is mixed with gelled aluminium sulfate sludge from the scum storage tank 19 and then subjected to a heat reaction to form aluminium sulfate. Thus, this method greately cuts down on the procurement cost of crystalline alumininm sulfate and also obviates the needs for excess apparatus

Title: Chorus effect device
Inventor: SUENAGA AKIRA
IPC: G10L21/04
Filed: 1995-04-26
Abstract: PURPOSE:To get chorus effect, using a pitch converter. CONSTITUTION:An audible frequency signal picked up with a microphone 12 is inputted into pitch converters 14-1 to 14-n. Moreover, the pitch of the audible frequency signal of the microphone 12 is detected with a pitch detection signal 16, and is supplied to a control circuit 18. A plurality of scale signals to show different scales are inputted already from a keyboard or the like into the control circuit 18. The control circuit 18 compares the pitch of the audible frequency signal with each pitch based on each scale signal and decides the quantity of each pitch conversion for converting the audible frequency signal into the pitch corresponding to each scale signal. Based on the quantity of these pitch conversion, pitch converters 14-1 to 14-n convert the pitches of the audible frequency signals of the microphone 12. Chorus effect can be gotten by these signals whose pitches are converted and original signals of the microphone 12.

Abstract: PURPOSE:To obtain prompt heating performance, high temperature radiation, reduce cooking time and scorch food to be cooked more easily by installing a sheet-like heating element on a space sustaining material, and allowing the greater part of the heating element to be located into a space. CONSTITUTION:To prevent the penetration of microwave, it is acceptable to specify the maximum diameter of a through hole of a microwave shielding board 2 as 5mm and smaller. A sheet-like heating element 3 is a metal heating element made of stainless steel, nickel, and chrome laid out in a zigzag manner. A space sustaining member 5 is installed between the high frequency shielding board 2 and the sheet-like heating element 3 while a metal heating element 4 is designed to be heat resistant and corrosion resistant so that it may not be subjected to a short circuit when the metal heating element comes into contact with the microwave shielding board 2. Furthermore, it is made of ceramic or glass which is excellent in electric insulation. The sheet-like heating element 3 is installed on the space sustaining member 5. Moreover, the contact area between the sheet-like heating element 3 and the space sustaining member is small, which minimizes thermal diffusion induced by thermal conduction. As a result, the sheet-like heating element 3 reaches high temperature in a short time. It is, therefore, possible to reduce cooking time and scorch a heated substance more easily.
