Abstract: PURPOSE:To execute self-running in a curve without using an expensive angular velocity sensor by detecting a diameter of curvature from a difference of rotation quantities of the left and the right driving wheels. CONSTITUTION:The rotation quantity is detected by a rotation quantity detector such as a pulse encoder, etc., attached to each driving wheel 41, 42, a difference of the rotation quantities of the left and the right driving wheels 41, 42 is calculated at every prescribed period, it is compared as a difference of the rotation quantities corresponding to a prescribed diameter of curvature with a set value set in advance to a curve setting device 59, and an error of the diameter of curvature is corrected. Also, a difference of integrating values of the rotation quantities is proportional to a bend angle, therefore, by detecting a fact that this difference of the integrating values reaches a prescribed bend angle set to an angle setting device 60, the end of the curve can be detected without providing specially a position detecting means 2. In such a way, self-running in a curve can be controlled at a low cost without using an expensive angular velocity sensor.

Filed: 1991-02-19
Abstract: PURPOSE:To eliminate consideration of anticorrosive material of a temperature sensor while enabling the measurement of the temperature of a fluid measuring a flow rate by incorporating a temperature sensor into an electrode. CONSTITUTION:A metal pipe 3 is insulated from a fluid with a lining 2 and an electrode 1 is also insulated from the pipe 3 with the lining 2 and an insulation spacer 4. Moreover. the electrode 1 has the lining 2 at a conical tapered part pressed and a washer 5 and a terminal 6 grasped on the opposite side and fixed with a nut 8 to be kept airtight. A hole is worked previously in the electrode 1 and a temperature sensor 9 and a lead 13 are incorporated with an adhesive 12, which allows the measurement of the temperature of the fluid measuring a flow rate. As the electrode 1 protects the sensor 9, this eliminates the need for considering a anticorrosive material as thermometer. Since the thickness of the electrode 1 is as small as 2-3 mm, the measurement of the temperature is accomplished accurately with a higher responsiveness.

Title: Container for liquid
Inventor: KIRITAKE MASAYOSHI
IPC: B65D47/40
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To permit no liquid to stay in the vicinity of an discharge port of a nozzle and avoid such inconvenience that liquid flows out against user's intention on account of the inflation of air in a container main body by a method wherein grooves which have a capillary action and which extend from the discharge port toward a liquid storage chamber are provided in an inner face of the nozzle. SOLUTION: Liquid 3 is contained inside a liquid storage chamber 6 of a container main body 1 made of plastic, which is deformable by pressing and has elastically restoring properties, and a tapered conical nozzle 2 having a discharge port 4 through which the liquid 3 flows out when the container main body 1 is pressed, is screwed to a top end of the container main body 1. Further, grooves 5 whose respective widths are gradually made narrower toward the liquid storage chamber 6 from the discharge port 4 so as to have a capillary action, are provided in an inner face of this nozzle 2. By this method, a capillary force becomes stronger in a position near the liquid storage chamber 6 than that at a tip end of the nozzle 2, and the liquid 3 is made easier to move toward the liquid storage chamber 6.  Furthermore, the movement of the liquid toward the liquid storage chamber becomes most effective if a bore diameter of the discharge port 4 is made to be 0.5-2.0mm and if the viscosity of the liquid 3 is made to be 100-5000Pa.s.
