Abstract: A cleaning implement 1 including a cleaning article 10 having a pocket 15 and a holder 20 adapted to be inserted into the pocket 15 to hold the cleaning article 10. The pocket 15 of the cleaning article 10 has a counter bumping portion 18 in the middle between the inlet opening at one end and the opposing end thereof. The holder 20 includes a handle 21, an insertion portion 22 extending from one end of the handle 21, and a retaining means 24 for retaining the vicinity of the inlet opening of the cleaning article 10. The insertion portion 22 has a bumping portion 23 that allows the insertion portion 22 to be inserted into the pocket 15 with no substantial obstruction until it reaches a bumping position where it bumps against the counter bumping portion 18 and then restricts further insertion beyond the bumping position.

Abstract: An allergen inactivating agent is provided which has no adverse effects on the human body and which does not cause problems such as color development.

Abstract: A cleaning sheet adapted to be attached to the head (20) of a cleaning tool (2). The cleaning sheet has a wiping portion (1A) that is disposed on the bottom of the head (20) when the cleaning sheet is attached to the head (20). The cleaning sheet has projecting parts (10) and (11) in the wiping portion (1A) which stick out of the forward and backward edges of the head (20) by a projecting length M when the cleaning sheet is attached to the head (20). The projecting parts (10) and (11) have a repulsive force of 0.1 to 100 N/cm when deformed by a length M/3 in the direction opposite the projecting direction. The projection (10) preferably has pointed tips.

Abstract: A cleaning sheet adapted to be attached to the head (20) of a cleaning tool (2) and having a wiping portion (1A) adapted to be disposed on the lower side of the head (20). In the state attached to the head (20), the cleaning sheet has, in the wiping portion (1A) thereof, a plurality of tacky recesses (10) open to the front and the rear of the head (20). The cleaning sheet has pointed parts (10b) projecting to the front and the rear between borders (10a) of adjacent two of the recesses (10).

Abstract: A bulky sheet 1 has a network sheet 11 and a nonwoven fabric-like fiber aggregate 10 having fibers arranged on at least one side of the network sheet 11. The fibers of the fiber aggregate 10 is in entanglement among themselves and with the network sheet 11 to be unitary with the network sheet 11. The network sheet 11 is three-dimensionally shaped to form a number of protrusions and depressions, and the fiber aggregate 10 is united with the network sheet 11 along the contour of the three-dimensionally shaped network sheet 11 such that the bulky sheet, as a whole, has a three-dimensional profile with a number of protrusions and depressions.

Abstract: A process for producing bulky paper comprising the steps of transferring a fiber web (2) having a water content of 50 to 85% by weight to a patterning zone having a perforated patterning net (31) revolving along a suction unit; patterning the fiber web (2) in conformity to the perforated patterning net (31) by sucking the fiber web (2) which is held on the perforated patterning net (31) while applying 5 kcal/kg or more of heat to the fiber web (2) in a heat application zone simultaneously with or before or after the sucking of the fiber web (2); and then drying the fiber web (2) in a drying zone to obtain patterned bulky paper (3).

Abstract: A cleaning sheet comprises a network sheet and a nonwoven fiber aggregate formed by the entanglement of fibers of a fiber web and disposed on at least one side of the network sheet. The fibers of the nonwoven fiber aggregate are further entangled with the network sheet, forming a unitary body. The cleaning sheet has the breaking strength of 500 g/30 mm or more, and the elongation at a load of 500 g/30 mm is 10% or less. The fiber aggregate has the entanglement coefficient of from 10 to 500 m. The entanglement coefficient is expressed by the initial gradient of the stress-strain curve measured with respect to the direction perpendicular to the fiber orientation in the fiber aggregate.

Abstract: An intermediate frequency band-pass filter for providing a pass band, comprising a frame forming a hollow surrounded region, a shield plate mounted in the frame and dividing the hollow surrounded region into two spaces, the shield plate having a coupling window, and two resonators disposed respectively in the spaces and coupled through the coupling window, the shield plate having in an edge thereof a step serving as a trap which provides a frequency suppression capability in the vicinity of the pass band of the filter.

Abstract: A buffer amplifier circuit of a wideband tuner has an output transistor. The output terminal of this transistor is grounded through a matching transformer having two taps. One of the taps constitutes a terminal through which the output signal is delivered to a mixer circuit, while the other tap is grounded through a capacitor which constitutes, in cooperation with the matching transformer, a trap circuit. This trap circuit is adapted to trap a frequency which is about twice as high as the low region oscillation frequency of a local oscillator which produces an input to the buffer amplifier circuit.
