Title: Dial type input device
Inventor: SAYAMA TAKUYA
IPC: G06F3/0362
Filed: 1990-05-16
Abstract: PURPOSE:To improve a man/machine interface by changing the strength of force necessary for rotating a dial by a signal inputted from the outside of a dial type input device. CONSTITUTION:A rotation control part 15 moves a gear 27 with rubber in the contact direction with a rotation axis side rubber member 26 when an external input signal is large size and move the gear 27 in the reverse direction when the signal is small in size. When a signal proportional to the operational load state of an information processor 13 is applied to an external signal input part 16, the strength of force necessary for rotating the dial is increased and an operator can not easily rotate the dial. When the load is small, the dial load is reduced and the dial can easily be rotated. Thereby, the operator 12 can sense the operational load state of the processor 13 and can not obtain an unreasonable request exceeding processing capacity.

CONSTITUTION:When a control pressure is supplied from a solenoid valve 13 through a vacuum passage 14 only to a vacuum chamber 12a, a sectional area of a secondary air intake passage 11 is gradually increased to increase an amount of secondary air. A negative pressure in the vacuum chamber 12a gradually approaches to an atmospheric pressure upon generation of a lean signal, and the sectional area of the passage 11 is gradually decreased to decrease the amount of the secondary air. Then, in case of controlling an air-fuel ratio to a theoretical air-fuel ratio, as a control circuit 22 alternately generates a rich signal and a lean signal, the negative pressure in the vacuum chamber 12a is increased or decreased between the atmospheric pressure and a negative pressure Pe, and the amount of the secondary air is also changed to effect an air-fuel ratio control by an integral operation according to an actual air-fuel ratio.

Filed: 1989-05-24
Abstract: PURPOSE:To easily correct an optical axis shift which is caused after lens fixation by forming a holder for a lens from a material which can be bent and deformed plastically. CONSTITUTION:The lens holder 5 is manufactured by pressing a thin pipe mate rial made of iron alloy partially in a flange die. The lens 4 is soldered 6 to the lens holder 5 and fixed.

Title: Method for decomposing and removing carbon monoxide or carbon dioxide and removing equipment
Inventor: HAYASHI HIDEAKI
IPC: B01D53/32
Filed: 1990-05-18
Abstract: PURPOSE:To decompose and remove an ion and oxygen ion respectively by decomposing carbon monoxide or carbon dioxide introduced into a discharge tube by plasma which is excited by a high-frequency coil for generating inductive coupling plasma. CONSTITUTION:When gaseous CO2 7 is introduced into a discharge tube 1 from an introduction port 1a thereof and high-frequency electric power is supplied to a high-frequency coil 2 for generating IPC from a power source 3 for generating high frequency, gaseous CO2 7 in the discharge tube 1 is decomposed into C atom and O atom by inductive coupling plasma. Since ionization potential of C atom is lower than ionization potential of O atom, C atom easily becomes a positive ion. On the other hand, since electronic affinity of O atom is larger than electronic affinity of C atom, O atom easily becomes a negative ion. Therefore gaseous CO2 7 is almost decomposed and ionized into C<+> and O<-> in the optimum discharge conditions. When these decomposed and ionized ions are applied with an electric field from the electrodes 5, 6, C<+> ion 9 and O<-> ion 8 are attracted and moved to the electrodes, having respectively different signals and gaseous CO2, is decomposed and removed.
