Title: Purification treatment device for contaminated running water
Inventor: MORIMOTO HARUO
IPC: C02F9/00
Filed: 1992-11-20
Abstract: PURPOSE:To purify running water at low cost and safely by removing part of the running water in an upstream side and organic components in a downstream side by the use of microbes which decompose oily part and contaminated organic components contained in contaminated water. CONSTITUTION:A primary filter material 20 contains microbes which decompose oily part in the water permeable fiber, so that the oily part becomes entrapped in the fiber in a stage where the running water passes through the fiber, and is decomposed by oxidation due to the microbes. The running water passed through the primary filter material 20 runs through a secondary filter material 30. The secondary filter material 30 is a porous material such as low grade coal and also contains microbes which decompose contaminated organic components in the micro voids. The organic components in the running water stick to the porous material of the filter material 30 or a floating substance hits the filter material 30 and is precipitated when the components pass through the secondary filter material 30. In this case, the organic components captured by the secondary filter material 30 is decomposed by oxidation due to the microbes. Consequently, it is possible to purify the running water at low cost and safely.

Title: Multiplex wavelength led device and its manufacture
Inventor: PAIJIE EMU HORUMU
IPC: H01L27/15
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To generate various wavelengths, by laminating and arranging a 1st and a 2nd LED so that they emit lights in the same direction, transmitting the light emitted by one LED through the other, emitting the lights from the both through a single aperture, and mixing them at intensity level. SOLUTION: A heterostructure LED 30 is so constituted as to emit a green light with short wavelength and a heterostructure LED 20 is so constituted as to emit a red light with long wavelength. The LED 30 emits the short- wavelength light, so an active layer 25 and sealing layers 24 and 26 substantially transmit the light emitted by the LED 20. Further, contact layers 17 and 23 of materials which are relatively thin and heavily doped are formed and them the light emitted by the LED 30 is transmitted through them. Therefore, a multiwave device 10 is constituted having a single aperture or light emission region, and can generate various wavelengths by mixing the lights from the LEDs 30 and 20 at intensity level through the light emission region 35.

The metal cut operation fluid pressing force P2 is supplied at a pressing force (a+α mmHg) higher than an operation pressing force P1 (a mmHg) for the molten metal 1 to be supplied from the metal supplying pipe 6. Therefore, the molten metal 1 is forced down from the opening 6a by the metal cut operation fluid pressing force P2, and the molten metal 1 supply from the metal supplying pipe 6 into the plunger sleeve 11 is prevented.  Thereby, improvement of the product quality is achieved by preventing the molten metal from being supplied into the plunger sleeve 11 during injection, and the bubble remaining in the molten metal.

Title: Cooling device for original reader
Inventor: KAWAHARA SHINICHI
IPC: H04N1/00
Filed: 1994-12-26
Abstract: PURPOSE: To prevent heat from a light source mounted on a scanner from being concentrated near a home position by controlling the scanner so that it may be stopped at a position, separated from the home position after ending a reading operation. CONSTITUTION: The scanner is controlled by a control part 21 so that the scanner may be stopped at the position separated from the home position HP after ending the reading operation by the scanner. At this time, a 1st traveling body 4 and a 2nd traveling body 5 are in a standby state with leaving a satisfactory distance between them, so that both traveling bodies do not come adjacent to each other, and also, the bodies do not overlap each other. Thus, the ventilation is not arrested on the standby position. And also, when the reader is in a standy state where the reading operation is not carried out, obstacles arresting the ventilation do not exist near the home position HP, so that a contact glass near the home position HP and the atmosphere are efficiently cooled.  The retreat movement of the 1st and 2nd traveling bodies from the home position HP is accomplished by controlling a scanner driving motor 22 by the control part 21 after ending a series of the reading operation.

Abstract: PROBLEM TO BE SOLVED: To enable the switching from operation controlled by others to a self-controlled operation without fail, regardless of the existence of the components of rotating pulsation. SOLUTION: At switching from others-controlled operation being performed by applying specified frequency of application voltage to the winding of an armature to self-controlled operation whose phase is controlled, based on the position detection signal, the phase differences between the actual phases obtained based on the position signal and the phases of application voltage are sampled for a period equivalent to the last one revolution of the motor (S1).  Then, if it is in leading phase condition where the phase of the application voltage advances by a specified value or over, this controller decreases (S6) the duty ratio of the application voltage, and in addition if it is in a delay phase condition where the phase of the application voltage is delayed for a specified value or more from the actual phase, this increases (S10) the duty ratio of the application voltage, and when all of each phase difference signal detected for a specified period are contained in the specified phase difference range (S4), and when a part of each phase difference signal detected for a specified period is contained in the specified phase difference range and that the remainder of each phase difference signal advances is in a leading phase condition (S9), this the switching is performed (S11).
