Whereas a high masking effect can be secured in a space to which a masking sound is emitted, the degree of a discomfort a person existing in the space suffers can be reduced. In superimposition processing, a CPU 21 extracts sound signals in different intervals of a sound signal X12-n of a human voice, superimposes the extracted sound signals on each other on the time axis, and outputs a resulting superimposed sound signal X13-n. In shift and addition processing, the CPU 12 interchanges a sound signal, before a reference position, of a sound signal X16-n and a sound signal, after the reference position, of the sound signal X16-n (shift processing) and outputs a sound signal X17-n obtained by adding together a shift-processed sound signal X16′-n and the original, non-shift-processed sound signal X16-n.

To provide an image forming apparatus in which variations in the contact pressure produced between a photosensitive drum and a developing roller is suppressed, whereby image quality can be improved. A development unit and a drum unit are rotatably connected to each other with a link member interposed therebetween. Gears for transmitting a driving force are supported at two rotation support points of the link member, whereby the driving force is transmitted to the development unit.

In a masking sound generating apparatus, a band divider divides a target sound signal into a plurality of frequency bands to generate a plurality of band signals. An envelope signal generating part generates a plurality of envelope signals representing respective envelopes of the plurality of the band signals. A signal converter segments each of the plurality of the envelope signals into a plurality of frames, then specifies frames of segmented envelope signals which have an amplitude greater than a first threshold and less than a second threshold, and changes an order of the specified frames in an arrangement of the plurality of the frames. A multiplier multiplies each of the plurality of the envelope signals by a noise signal, each envelope signal having the order of the frames changed by the signal converter, and outputs the plurality of the envelope signals multiplied by the noise signal as individual band masking signals. An adder adds the individual band masking signals to output a masking sound signal capable of masking the target sound signal.

A method for manufacturing the electron-emitting device according to the present invention has a step of forming the electron-emitting film, and the electron-emitting film forming step includes a step of forming the plurality of particles made of a second material whose electric resistivity is lower than that of a first material into the first layer made of the first material containing oxygen and nitrogen.
摘要:
In a masking sound generation apparatus, a CPU analyzes a speech utterance speed of a received sound signal. Then, the CPU copies the received sound signal into a plurality of sound signals and performs the following processing on each of the sound signals. Namely, the CPU divides each of the sound signals into frames on the basis of a frame length determined on the basis of the speech utterance speed. Reverse process is performed on each of the frames to replace a waveform of the frame with a reverse waveform, and a windowing process is performed to achieve a smooth connection between the frames. Then, the CPU randomly rearranges the order of the frames and mixes the plurality of sound signals to generate a masking sound signal.

An amount-of-developer regulating apparatus configured to restrict the amount of developer carried on a developer bearing member. The amount-of-developer regulating apparatus includes a flexible developer amount regulation member having a contact portion configured to contact with a developer bearing member, and first and second holding portions configured to hold the developer amount regulation member and to contact with the developer amount regulation member at further upstream and further downstream in a direction where the developer bearing member is rotationally moved than the contact portion. With a pressure distribution of the contact portion as to the developer bearing member, there are a plurality of local maximum values in the direction where the developer bearing member is rotationally moved. Thus, the apparatus can be reduced in size, and also image concentration unevenness after long-term use can be prevented.
