IPC: F24F7/06
Filed: 1988-10-11
Abstract: PURPOSE:To make it possible to discharge smoke or oil vapor efficiently by installing an auxiliary air supply duct to the upper side of a duct where one end of an inhalator is arranged to face the upper surface behind a cooking utensil and ejecting controlled air current to an upper space above said cooking utensil with an auxiliary blower. CONSTITUTION:A main blower 3 is installed near a discharge section 2b of a duct 2 which is provided with an intake section 2a with one end opened to the upper surface behind a cooking utensil 1 and the discharge section 2b with the other end communicated with the outside. The main boiler is connected with an auxiliary blower 6 from the lower part of an auxiliary air duct 4 formed on the upper surface of the duct 2 by way of another air duct 5. The auxiliary blower 6 ejects controlled air current (as indicated by the arrows)a substantially horizontal direction from a discharge port 4a of the auxiliary air duct 5 to the space above the cooking utensil. This controlled current serves to inhibit the diffusion of smoke, oily vapor (denoted by the arrow A) upward and they are caught from the suction port 2a by the action of the main blower and discharged efficiently outdoors from the discharge section 2b, which makes it possible to carry out efficient air collection and ventilation and utilize the space above the coking utensil 1 effectively.

Title: Groebner basis generating method and device therefor
Inventor: NORO MASAYUKI
IPC: G06F7/72
Filed: 1994-10-20
Abstract: PURPOSE:To reduce the memory capacity and to perform an arithmetic operation at a high speed by omitting the calculation of a normalizing form in terms of a rational number when the normalizing form using a prime number (p) as a divisor is decided as 0. CONSTITUTION:A prime number selector means 5 selects a prime number (p). A 1st arithmetic means 6 uses the number (p) as a divisor to calculate a normalizing form of a pair of polynomials. When a deciding means 7 decides that the normalizing form is not 0 with the number (p), a 2nd arithmetic means 8 calculates a normalizing form in terms of a rational number. An omitting means 9 regards a fact that the normalizing form is 0 also with the rational number when the normalizing form is decided as 0 with the number (p) and omits the calculation of the normalizing form in terms of the rational number. A Groebner basis deciding means 21 confirms that a supplied polynomial set F is entirely normalized into 0 by an acquired polynomial set F1 to check the ideal equality and therefore decides whether or not the set F1 serves as the Groebner basis of the set F.

Title: Cusp magnetic field type ion source
Inventor: NAKAYAMA TAKAYUKI
IPC: C23C14/00
Filed: 1992-09-25
Abstract: PURPOSE:To provide uniform beam profile in which the beam does not defect at the center or periphery part by installing an auxiliary cathode in a mirror magnetic field generated between magnets in the inner walls of a plasma chamber and discharging electrons to the circumferential direction. CONSTITUTION:Electrons discharged out of a main cathode 4 are trapped in the center part of a plasma chamber mainly due to cusp magnetic field C and generate plasma and form beam profile having intense distribution at the center part. Meanwhile, the electrons out of an auxiliary cathode 9 are discharged to a mirror magnetic field M. In the mirror magnetic field M, since the magnetic field has -Z direction and the electron field is direction, the electrons do circular movement to theta direction along the inner walls 6 of the plasma chamber and without spining into the center part of the plasma chamber, the electrons are captured in the magnetic field M. Consequently, beam profile having intense distribution at the periphery part is obtained by the auxiliary cathode 9. As a result, beam prolife without any deflection at the center part is formed in the plasma chamber.
