Title: Method and apparatus for purifying metallic silicon
Inventor: YOSHIZAWA AKINOBU
IPC: C01B33/037
Filed: 1985-11-15
Abstract: PURPOSE:To purity high-purity metallic Si in excellent yield at low cost by utilizing a plasma arc discharge phenomenon and allowing a gaseous mixture of SiCl4 and H2 to react chemically to obtain liquid metallic Si and gaseous HCl. CONSTITUTION:A plasma arc discharge wherein potential difference is given between a crucible and an electrode is caused by an arc discharge generator. Liquid metallic Si and gaseous HCl are produced by chemical reaction from a gaseous mixture of SiCl4 and H2 which is simultaneously therewith blown out to a crucible side from the tip of the electrode by means of a feeding means of a raw material. As the liquid metallic Si is stored in the crucible the interval between the crucible and the electrode is controlled by a transfer means so that both the liquid level of metallic Si and the tip of the electrode always maintain a fixed interval. Thereby the stabilized plasma arc discharge is continuously generated. Still further the tip of the electrode rising to high temp. is cooled with an electrode cooling means to previously prevent fusion wear of the electrode.

Title: Magnetic recording and reproducing device
Inventor: ISHIZAWA YOSHIYUKI
IPC: G11B15/467
Filed: 1989-10-02
Abstract: PURPOSE:To quickly obtain a normal tracking state by stopping the switching action of a selector by a selector control means while a synchronizing signal is not detected by a synchronizing signal detection signal. CONSTITUTION:A synchronizing signal detection means is constituted of a synchronizing filter 5 and a synchronous detector 8 and the selector control means is formed of an SP2 detector 20 and an AND gate 22. In the case of starting reproducing, when the azimuth of a reproducing head becomes reverse to reproduced azimuth, the synchronizing signal is not reproduced by the reproducing head and is not extracted by the filter 5, so that an SP2 signal is not outputted from the detector 8. Then, the control means stops the output of a switching signal to the selector 4 from a frequency divider 23 and the selector 4 is kept in a state where it selects either of the heads. When the azimuth head begins to scan the track of the same azimuth because tracking is shifted, head switching and tracking control are immediately started by the selector 4. Thus, the normal tracking control state is quickly obtained and data is reproduced.

Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic cooker capable of quickly raising the temperature of the edible oil in a pan without excessively raising the temperature of a control means in the case of using a pan hard to transmit the heat to the edible oil. SOLUTION: When temperature of the edible oil (oil temperature) in a pan is judged to be lower than the set temperature in a step S662, and the oil temperature is judged to be yet below the set temperature in a step S665, and the temperature of a top plate, placing the pan is judged to be higher than the upper limit temperature(Ta) of the top plate in a step S666, heating output is set at 400 W lower than the maximum fire power. In the case where the temperature of the top plate is judged to be lower than Ta in the step S666, the heating output is set at the maximum heating power (1000 W for example). Namely, an electromagnetic cooker continuously heat the pan with any one of the maximum heating power and the heating power weaker than the maximum heating power till the oil temperature reaches the set temperature once.

Title: Evaluation of corrosion behavior of zirconium alloy
Inventor: NONAKA YOSHIO
IPC: G01N33/20
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To estimate the corrosion in a nuclear reactor by evaluating the corrosion behavior on the basis of the concn. change of constituent elements of a precipitate in a zirconium alloy eluted into a matrix by the collisions of neutrons or the like. SOLUTION: An intermetallic compd. consisting of Zr, Fe and Ni is precipitated in zircalloy-2 being a zirconium alloy used in fuel of a boiling water light- water reactor or the like. Fe and Ni are eluted from this precipitate by the expelling due to fast neutrons and the solid soln. concn. of them in an alloy matrix increases but, by calculating the Fe+Ni solid soln. concn. change rate immediately after the start of steady operation by predetermined operation using, for example, the chemical compsn. of zircalloy-2, the particle size or compsn. of the precipitate or fast neutron irradiation quantity, the corrosion behavior in a nuclear reactor can be evaluated. If the solid soln. concn. change rate is large, dense and uniform corrosion is formed but, if it is small, nodular corrosion wherein corrosiveness is easy to deteriorate is generated.

Abstract: PURPOSE:To enable a terminating subscriber to get information of the originating subscriber or the originating time of a call even during his speaking or absence by storing not only the telephone number of the originating subscriber but also information related to the call such as the originating time and information of the originating subscriber in a second storage part. CONSTITUTION:When detecting it by an absence button 6 and a hook switch 7 that the terminating subscriber is absent or speaking, a control part 2 takes in telephone number information of the originating subscriber transmitted from an ISDN line and collates it with telephone number data stored in a first storage part 3. When a telephone number coinciding with taken-in information is stored in the first storage part 3, this telephone number data, the name and other data stored together with this telephone number data, and the time of originating called from a timer 5 are stored in a second storage part 4. Thus, not only the telephone number of the originating subscriber but also useful data related to call originating like the name and the originating time are reported to the user by display though the call comes during his absence or speaking.

Title: Combustion chamber of multi-valved engine
Inventor: KIMURA TAKAAKI
IPC: F01L1/00
Filed: 1988-10-13
Abstract: PURPOSE:To restrict quantity of airflow through an inlet valve at the beginning of opening by covering the outer face of each valve with the outside face of a combustive recessed portion. CONSTITUTION:A combustive recessed portion 4a has outside faces 4b, which face the upper portion of a cylinder port 3a and have larger diameters than the major diameters of inlet, exhaust valves 5, 6. The outside faces 4b are linked with each other in between the inlet, exhaust valves 5, 6 to form on the lower face of a cylinder head 4 approximately triangular squished areas S which are formed into the cylinder port 3a and the outside faces 4a and projected in the direction of a cylinder axial center. Therefore, as the inlet, exhaust valves 5, 6 have the outsides covered with the outside faces 4b of the combustive recessed portion 4a, overlap of the inlet valve 5 at the beginning of opening can be effectively decreased. It is thus possible to improve combustive stability in a low-speed drive.
