Inventor: ISHIZAKI NOBUO
IPC: B01J20/30
Filed: 1984-03-26
Abstract: PURPOSE:To obtain the titled composition which is highly effective in adsorbing and removing an irritant gas such as acetaldehyde by dispersing ultrafine powdered activated carbon having specified pore volume, basicity, and mean particle diameter into an aq. soln. of an anionic high molecular electrolyte. CONSTITUTION:Ultrafine powdered activated carbon having >=300Angstrom pore diameter, >=0.4cc/g pore volume, >=9pH basicity, and <=30mu mean particle diameter is dispersed into an aq. soln. of anionic high molecular electrolyte (e.g., sodium alginate) to form a pasty composition. And the composition is deposited on an unwoven fabric sheet. The pasty composition and the adsorptive sheet are highly effective in adsorbing and removing an irritant gas such as acetaldehyde. Since the activated carbon having high basicity is used, the activated carbon interacts strongly with the anionic high molecular electrolyte. Consequently, the adsorptive power is not decreased by an fixing agent.

Filed: 1990-03-08
Abstract: PURPOSE:To obtain the efficient antenna which has narrow antenna mounting area and is well matched with the wavelength and frequency band of a radiated electromagnetic wave by folding end parts of dipole antennas and grounding the folded end parts through electric resistances. CONSTITUTION:The folded half-wavelength dipole antennas 11a and 11b are constituted symmetrically to the same size and the end parts are folded respec tively. One-terminal sides of the electric resistors 10a and 10b are connected to the folded tips of the antennas 11a and 11b and the opposite-side terminals are grounded. The dipole antennas have the effective length of the overall length l+2d equal to lambda/2 so as to match the effective length of the antennas is equal to lambda/2 since reflection is obtained at reflection points when the antennas are folded and the shortening effect of the wavelength is therefore obtained. Consequently, the antenna which has small surface area and also has the effec tive length and band well matched with a specific electromagnetic wave is obtained.

Title: Continuously variable transmission
Inventor: ISHIMARU KO
IPC: F16H35/10
Filed: 1986-03-19
Abstract: PURPOSE:To reduce the dimension of the captioned continuously variable transmission and prevent the engine stall on sharp brake application by installing a connecting clutch which can connect and disconnect a power transmission passage and a one-way clutch which can transmit a driving power in the direction of advance from the engine side in parallel, in the power transmission passage. CONSTITUTION:In the low speed advance, a driving power is transmitted only through a one-way clutch 43 by releasing a connecting clutch 40, and in other cases, the driving power is transmitted through the connecting clutch 40. Therefore, when the car speed is sharply lowered by the sharp brake application, and the revolution speed of the driving pulley 16 of a V-belt type continuously variable transmission mechanism 29 lowers below the idling speed of an engine, the one-way clutch 43 is put into the idling state. Therefore, the engine speed is not compulsorily lowered below the idling revolution speed, Thus, the engine stall on sharp brake application can be certainly prevented.
