Title: Method for measuring ferritic nucleation velocity and rate of growth
Inventor: NANBA SHIGENOBU
IPC: C21D6/00
Filed: 1995-03-02
Abstract: PURPOSE: To easily and precisely obtain nucleation velocity and parabolic growth rate constant by computing under specific conditions by using respective measured values of ferritic volume fraction and grain size at the time of ferritic transformation from austenitic single phase region. CONSTITUTION: Ferritic transformation is performed by means of isothermal holding at a temp. not higher than the Ae3 point from austenitic single phase region. Ferritic volume fraction Xf and grain size Df are measured, and nucleation velocity Is and parabolic growth rate constant α are determined from equations 1, 2, 3.  In these equations, S is the interfacial area of austenite per unit volume before the initiation of ferritic transformation, Cg is the carbon concentration of the austenite in the interface, Ca is the carbon concentration of the ferrite in the interface, C0 is the carbon concentration before the initiation of transformation of austenite, (t) is isothermal transformation holding time, ns is the number of ferritic nuclei per austenitic unit interfacial area forming in the isothermal transformation holding time (t), and πis the ratio of the circumference of a circle to its diameter. By controlling the ferritic structure, control of material and improvement of yield are enabled.

Title: Ultrasonic object detecting device
Inventor: MIZUNO MASAO
IPC: G01S15/04
Filed: 1978-04-13
Abstract: PURPOSE: To ensure an accurate detection of the object position with no effect of the temperature by counting the ultrasonic reflected wave arrival time from the object which varies by the temperature via the natural frequency number of the ultrasonic oscillator which also varies by the temperature.  
     CONSTITUTION: The intermittent wave of the ultrasonic wave given from head 1 is sent out toward road surface 2. Then reflected wave arrival time t 1  from surface 2 or reflected wave arrival time t 2  from car 3 is decided by period Tg of the car detection gate provided between t 1  and t 2 , thus detecting the presence or absence of the cars. In such case, t 1  and t 2  vary by the change of the acoustic velocity caused by the temperature change, and thus misdecision may be possibly caused based on the fixed Tg. In this connection, the fact is utilized that natural frequency number fO of ultrasonic oscillator 101 varies by the temperature, that is, the pulse frquency supplied to counter 113 of gate circuit 112 is converted into frequency fO' which corresponds to the change of the acoustic velocity. As a result, the arrival time of the reflected wave from detector 115 changes by the counting velocity of counter 113 of changes in response to Tg even though it is changed by the temperature change, thus ensuring an accurate decision of the distance.

IPC: F23D11/10
Filed: 1984-03-08
Abstract: PURPOSE:To restrict an accumulation of tar on a gasification surface and get a stable combustion having better quality by a method wherein a fuel nozzle is placed in a gasification chamber in such an orientation as the fuel is injected horizontally or in an inclined upward direction and at the same time almost of all the combustion air to be supplied from a blower pipe is caused to flow on the bottom surface of the gasification chamber. CONSTITUTION:Fuel is gasified at a gasification surface 7 arranged at the inner wall of a gasification chamber 1 together with combustion air and supplied to an upper combustion part 8 while being mixed and then ignited. At this time, a fuel nozzle 6 is placed in such a manner as fuel is injected in a gasification chamber 1 in a horizontal direction and at the same time a blower pipe 4 is inclined in such a way as it is located at a lower position from an upstream side of the combustion air to a downstream side thereof and it is connected in the gasification chamber 1. With this arrangement, since the combustion air is not directly injected against the striking surface 7a, it is possible to restrict to a certain degree that a temperature near the striking surface 7a is excessively decreased, resulting in that an excessive accumulation of tar in the striking surface 7a is not made.

Filed: 1979-04-13
Abstract: PURPOSE:To reduce defective products due to injury on the wire and to improve efficiency of manufacture by a method wherein a blade gap only where a coating of a winding wire is injured is contrived so as to prevent injury properly. CONSTITUTION:An angle theta formed by winding wires which are inserted into a gap W between blades 3, 3 is represented by the formula theta=sin<-1>(W-d)/d, (d represents a diameter of a winding wire), the angle theta must be smaller value to decrease friction working on the winding wire, and if a diameter of a winding wire is held constant a gap must be decreased for this purpose. Accordingly if on constructing a four staged distributed main winding of a two poled single phase induction motor, an injury due to blades 3 on the coating of winding wire occured at the winding having the wire diameter of 0.966, the gap W of 1.4 and turns of 52 and theta took 26.7 deg., a remedy is taken as followings: the gap W is set at about 1.1, and the angle is set at approximately 8 deg.. By this remedy defective products due to injury upon the winding wire are mitigated and efficiency of manufacture is improved.
