Title: Course guiding system
Inventor: ONISHI HIROFUMI
IPC: B65G61/00
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To allow a user to register with ease a course information and such guide information as voice and still picture to a course guide system which guides a car to a cruising course. SOLUTION: In a center system 2 provided at a business branch 1, a course information 14 and a guide information 3 for a course are registered. Since a cruising business course can be registered or changed freely while a landscape still picture on a course and such guide information as voice for course in direction can be registered or modified freely, a detailed and accurate guide information is registered at such point on a course as an intersection which is easy to be mistaken. The information is integrated with a map data 4, which is stored in an on-vehicle system 7 set in a business car 6. The on-vehicle system 7 displays the registered course information 14, and when the business car 6 approaches a registered point in the guide information 3, such side information as landscape, image, and voice are outputted for guiding a driver.  Since the center system 2 has the course information 14 and the guide information 3 registered, a travel simulation can be performed with the center system 2 in advance, so the driver fully know a course before driving the business car 6.

IPC: C25B13/00
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To obtain titanium (III) sulfate having an extremely low content of impurities derived from cations except Ti ion by subjecting an aqueous solution of titanium (IV) sulfate introduced into a cathode chamber of an electrolytic bath divided into an anode chamber and the cathode chamber by a bipolar membrane to electrolytic reduction.

The composite membrane impermeable to ions except hydrogen ion and hydroxyl ion is preferable for the purpose. High-purity titanium (IV) sulfate is used. In order to carry out stable electrolytic reduction from an early stage, an aqueous solution of the titanium sulfate is made into an acidic solution having pH 0-5 and the concentration of the solution is 10-200 g/litter calculated as TiO2. An aqueous solution of sodium hydroxide having 0.2-3 N concentration is used as an electrolyte to be used in an anode chamber. The current density is 0.1-100 A/dm2 and the temperature is 0-100 deg.C. Iron, stainless steel, etc., are used as a cathode and platinum/titanium, etc., are used as an anode.

Filed: 1986-07-16
Abstract: PURPOSE:To make it possible to remove the air defficiency of flame, to prevent poor combustion and also to prevent soots, carbon monoxide and the like from being produced by constituting an outside air passage of the inner wall and the outer wall of a combustion chamber, an providing a plurality of air injection holes opening toward the combustion chamber at a part of the outside air passage. CONSTITUTION:When a fuel 8 is delivered to the burner under pressure, it is sprayed through a fuel spraying nozzle 7. Upon this occasion, the fuel comes into collision with circulating air beforehand ejected through air holes 5a of a vaporizing cylinder 5 by a blower 19 for use in combustion air, and is mixed therewith. Further, the fuel 8 is ignited by a spark discharge before starting the spraying of the fuel by an igniter 15. Thereafter, the vapor of the fuel vaporized by receiving the radiant heat of a combustion flame 23 is mixed with circulated air. The thus prepared mixed gas rises up within an auxiliary cylinder 6 while circulating air to form the flame 23 at suitable positions of air holes 5a and to continue the combustion. At this time, when the flam 23 is short of air due to a change in atmospheric temperature, and the like, a flame 24 is elogated and comes into contact with the inner wall 11 of the combustion chamber 4 and rises up. However, since it is brought into collision with an airstream through an air ejection hole 13a, fresh air is supplied, combustion is promoted, and soots and carbon monoxide produced are reduced.
