Title: Path guiding device for vehicle
Inventor: KISHI KOJI
IPC: G10L13/00
Filed: 1993-07-12
Abstract: PURPOSE:To surely make path guidance with sound announcement even when branch points such as intersections or interchanges exist nearby in a path guiding device for a vehicle by sound or screen display. CONSTITUTION:A path guidance controller 26 reads out the map information around its vehicle from a map information memory section 10, and it superimposes and displays the present vehicle position and advance direction and the path stored in a path memory section 24 on a display section 28. When the position of the vehicle approaches an intersection where the course is to be changed, the path guidance controller 26 instructs a sound controller 30 to generate a sound corresponding to the path guidance at the intersection. The sound controller 30 compares the distance dx from the previous intersection with a prescribed distance. When the distance dx is the prescribed distance or below, the output timing of the sound announcement of 'arriving at ***soon' after leaving the previous intersection is controlled, and the sound guidance is surely made immediately before the intersection where the course is to be changed.

Inventor: KOYAMA HARUO
IPC: G03G21/00
Filed: 1983-09-19
Abstract: PURPOSE:To improve a copying efficiency at the time of a both surface copying by constituting so that a distance extending from a fixing device to a lead-in roller for inversion becomes longer than a length of a copying paper, and also speed of a returning belt becomes higher than carrying speed of a main machine. CONSTITUTION:A length of a carrying path which reaches a lead-in roller 29 through a feed-out roller 26 from a fixing device 25 is made longer than a length of the carrying direction of a copying paper A to be used, and also a feeding speed of a returning belt 33 is made faster than a form carrying speed of a copying machine body. Accordingly, at the time of a both surface copying, even if a speed of the returning belt 33 is increased, it does not occur that the copying paper A is spread over the fixing device 25 and the lead-in roller 29, drawn and broken. Therefore, in case of the both surface copying, the copying efficiency can be improved by increasing a speed of the belt.

Abstract: PURPOSE:To improve the control performance and serviceability by providing both the outdoor unit and indoor unit with transmitting and receiving capabilities and defining the transmission demand signal which demands the outdoor unit to transmit its signal within the control signal from the indoor unit to the outdoor unit so that the two-way signal transfer may be conducted. CONSTITUTION:In its S1 cycle, the indoor unit MPU1 11 sends out the 4 bit transmission demand signal DI1 following the interruption bit from the output port SO1 12, and, after a time T4(0<=T4<=T3), it brings the output port SO1 12 to the logic level H and the input port SI1 13 to the interruption accepting condition so as to be prepared for the S2 cycle. The outdoor unit MPU1 21 receives and evaluates the transmission demand signal DI1 by its input port SI1 22, and then identifies that the following cycle is the transmission mode from the outdoor unit. The following cycle is initiated when the outdoor unit MPU2 21 transmits the interruption signal from the output port SO2 23 after a time T1 after the interruption of the S1 cycle is accepted. The control signal from the output port SO2 23 is transmitted to and read as that which is logic-reversed by the input port SI1 13 of the indoor unit MPU1 11. The S3 cycle is the signal transfer mode from the indoor unit to the outdoor unit which is initiated after the time T1.

Title: Separation and removal of ash included in active carbon
Inventor: TANGO HIDEHIRO
IPC: C02F1/28
Filed: 1979-12-29
Abstract: PURPOSE: When an active carbon that has been used in organic liquid-waste disposal is reactivated oxidatively by a wet process, the reactivated product containing ashes of small particle sizes is diluted with clean water to separate and remove the small particle ash with the aid of electrokinetic potential.  
     CONSTITUTION: Clean water is added to the product reactivated in the reactivator, which is composed of active carbon and ashes of relatively small size particles to dilute it. The addition of clean water raises the electrokinetic potential of the ash particles to cause disaggregation between the active carbon and the ash particles and the difference in sedimentation speed between them separates the ash particles. The amount of water added is, when the total hardness of the reactivated product is low, for example, less than 100, 2W5 times the reactivated product. When the hardness is high, for example, higher than 100, clean water is added in an amount of 2W10 times that of the product and additionally an ion blocker such as sodium hexametaphosphate is added.
