Title: Driving controller for mobile vehicle
Inventor: HATTORI AKIRA
IPC: G05D1/02
Filed: 1992-06-10
Abstract: PURPOSE:To offer the steering information to secure a stable and proper driving line of a vehicle by storing the driving actions of a driver as the driving rules and also processing the road linear information obtained by an image processing means based on those stored driving rules for calculation of the steering angle of the vehicle. CONSTITUTION:An image processing means 12 extracts the road linear information on plural front watching points out of the images which are photographed by a photographing means 11 that is attached to a vehicle and photographs the front road. Meanwhile, the driving actions of a driver are previously stored by a driving rule storage means 13 as the driving rules. Then, a steering angle calculation means 14 processes the road linear information on the watching points based on the driving rules and calculates the steering angle of the vehicle. Thus, it is possible to output the smooth command steering angle signals to secure the driving equivalent to an expert driver with no unstable control output despite the partial mismeasurement, the measurement errors of the road linear information on the white lines, etc.

Title: Heat treatment method
Inventor: HARAOKA TSUTOMU
IPC: H01L21/205
Filed: 1994-07-05
Abstract: PURPOSE:To reduce the amount of impurities like water content which are brought into a reaction tube. CONSTITUTION:After a wafer W is treated in a reaction tube 2, a wafer board 5 is unloaded and transferred from a heat insulating cylinder onto a mounting stand 7 in the lower position outside the reaction tube 2. In this state, the transferring work between a wafer W which has been treated and a wafer W which is not yet treated is performed. Contact time of the heat insulating cylinder with the air is shortened, by loading the heat insulating cylinder into the reaction tube 2, and raising the temperature of the inside of the reaction tube 2 higher than or equal to the temperature to be treated, while the transferring work of the wafer W is performed. Thereby the amount of impurities like water content which are absorbed by the heat insulating cylinder becomes little, and the impurities are left from the heat insulating cylinder by the heat in the reaction tube 2, so that the amount of impurities in the reaction tube 2 is reduced at the time of heat treatment.

Title: Heat pump type hot water supplying device
Inventor: YASUDA TADAO
IPC: F24H1/00
Filed: 1982-10-07
Abstract: PURPOSE:To provide the titled device which is inexpensive and detachably mounts a hot water temperature regulating valve and a safety valve for heating control, by integrally constituting the regulating valve and the safety valve so that the regulating valve may be easily maintained and inspected. CONSTITUTION:A hot water temperature regulating valve 5 is integrally provided with a safety valve 2. That is, the hot water temperature regulating valve cap 16 has a hot water temperature regulating valve unit 5a incorporated therein, and is screwed in the safety valve 2. When a water temperature is lowered, the pressure of water (hot water) supplied from a heat exchanger 4 is imposed on a valve body 22 at a piston 21. A small diameter port is defined in the valve body 22 for setting a minimum flow rate. Thus, a minimum flow rate of valve is predetermined. On the other hand, when the piston 21 is pushed outwardly by means of a temperature sensable cylinder 20, a clearance is defined between the valve body 22 and the cap 16 for thereby increasing the flow rate. In this manner, the temperature sensable cylinder 20 is adapted to sense the hot water temperature for regulating the flow rate. In the event that the deposit of scale is built up on a valve seat 22a or the valve body 22 itself for causing a malfunctioning valve during the actuation of valve body 22, the valve can be replaced with a new one in a very simple manner of merely removing a hot water temperature regulating unit 5a integrally with the valve cap 16 from a safety valve body 2a.
