Abstract:
On the surface of an ink-permeable sponge material having open cells, a melted portion and an unmelted portion are formed by a thermal head printer controlled by a memory processor for desired imprint data to prepare a stamp having the unmelted portion as an ink oozing imprint surface. Furthermore, a stamp material plate comprising the tape-like sponge material is wound up in the form of a roll and then received in a cassette case, and a stamp material cartridge comprising this cassette case is mounted in a cartridge receiving section of the thermal printer capable of printing in a tape form. A print image set by input from a keyboard or external input is printed on the stamp material comprising the sponge material fed from the cartridge by the thermal head, while the stamp material is pressed, to form a concave having a depth of 0.01 mm or more, thereby preparing a print plate for a stamp having a suitable length.A process for preparing a stamp of the present invention comprises simple steps, and therefore the high-quality stamp can be promptly provided.
Abstract:
A cartridge containing a thermosensitive stencil original comprising a tape-formed thermosensitive stencil original which is to be perforated to create a print image, a pressing member for pressing the thermosensitive stencil original, and a cassette case having the pressing member disposed therein. The thermosensitive stencil original is also accommodated inside the cassette case so that the stencil original may be carried out from the cartridge. The mirror image of the desired print image is perforated onto the surface of the thermosensitive stencil original.
Abstract:
A knock-out type mechanical pencil has a supporting rod mounted with an eraser at its rear end and axially slidably engaged within the interior of a cylindrical knock-button. A tubularly cylindrical weight is axially slidably engaged around the supporting rod. A cylindrical magnet is axially magnetized and secured to the inner peripheral surface of the knock-button. An annularly inwardly raised guide portion is formed on the inner peripheral surface of the knock-button for guiding the weight to the axial line of the knock-button when the weight is axially slidably dropped downwardly toward the writing tip of the pencil. To protrude and fix an eraser from the rear end of the tubular cylindrical body, the rear end of the pencil is tilted downward. To automatically contain or retract the eraser in the knock-button, the writing tip of the pencil is directed downwardly in writing state. Thus, this mechanical pencil can stably perform an erasing operation with an eraser without any rocking motion of the eraser in axial direction nor rotation of the eraser.
Abstract:
Provided is a manufacturing method of forming an airtight container including an electron beam irradiation process for irradiating an electron beam to a non-evaporable type getter that has not been activated so as not to activate the non-evaporable type getter, and a sealing process for sealing a seal portion after the electron beam irradiation process.
Abstract:
In order to prevent a spacer from being charged by using a plate shaped spacer covered with a high resistance film, the present invention is aimed at preventing irregular displacements of electron beams emitted from adjacent electron-emitting devices and suppressing displacements of impinging positions of the electron beams emitted from the adjacent electron-emitting devices even with a slight displacement of an installation position of the spacer. The spacer is disposed along a row directional wiring. The high resistance film is allowed to come into contact with a metal back and the row directional wiring to achieve electrical connection therebetween. Contact portions between the high resistance film of the spacer and the row directional wiring are provided at predetermined intervals.

Abstract:
An image forming apparatus comprises first and second substrates, a support frame arranged between the first and second substrates, and surrounding a space between the first and second substrates, electron emitting devices arranged on the first substrate facing the space, and an image forming member arranged on the second substrate. A spacer is disposed in the space between the first and second substrates, and a conductive film is arranged on the second substrate to surround the image forming member. The conductive film is supplied with a potential lower than that applied to the image forming member, and the spacer has a length greater than that of the image forming member. Each longitudinal end of the spacer is arranged between the inner periphery of the support frame and a respective plane through which a corresponding end of the conductive film extends perpendicularly to a principal surface of the second substrate.
Abstract:
A display apparatus includes a vacuum case having a face plate and a rear plate with a conductive member on a surface, electrodes facing the conductive member in the vacuum case, and a spacer abutting one of the electrodes. The spacer has a concavity, and the interior surface of the concavity abuts the conductive member.
Abstract:
An irregular shift of the electron beam caused by a spacer is compensated without making a design change of the spacer. A rear plate 1 in which an electron source substrate 9 disposed with plural electron-emitting devices 8 emitting the electron is fixed and a face plate 2 in which a metal back 11 for accelerating the electron is formed are disposed in opposition to each other, and these plates are supported by the spacers 3 with constant intervals, and the initial velocity vector of the electron emitted from the electron-emitting device 8 is different according to the distance from the spacer 3.
Abstract:
Speech characteristics are obtained using a minimum of parameters, which correspond to auditory perception characteristics, without carrying out spectral analysis, by determining an ACF (autocorrelation function) of a speech signal collected by a microphone, and deriving from the ACF a value Φ (0) of when a delay time of the ACF is 0, a delay time τ1 and an amplitude φ1 of a first peak of the ACF, and an effective duration time τe of the ACF. Furthermore, it is possible to achieve highly accurate recognition that reflects human perception in actual sound fields by determining an interaural crosscorrelation function (IACF) of the speech signal, and extracting from the IACF a maximum value IACC of the IACF, a delay time τIACC of a peak of the IACF, and a width WIACC of the maximum amplitude of the IACF, and including these IACF factors, that is, spatial information of the sound field.
