A method for fabricating a flat, light-emitting display panel includes the steps of applying frit seal to the pin electrodes in a state of pressing the rear panel against the front panel to keep them in contact with one another using a flat plate having an opening formed at a position corresponding to each of the pin electrodes; drying the frit seal to fix provisionally the rear panel to the front panel; detaching the flat plate from the both panels; applying frit seal to an end of the front panel and a side face of the rear panel; and burning the whole of components. The sequence of the application of the frit seal to the pin electrode and the application of the frit seal to the end of the front panel and the side face of the rear panel may be altered. The frit seal having flowability less than the frit seal applied to the pin electrode is applied to the end of the front panel and the side face of the rear panel.

A signal transmitter mounted on a wheel of a vehicle is disclosed. The transmitter includes a stem member and a cap member being arranged to be detachably mounted on the stem member. The stem member serves as a tire valve when the cap member is detached from the stem member. The stem member detects an tire air pressure smaller than a predetermined level when the cap member is attached to the stem member. The cap member transmits a warning wave signal based on the detection of the stem member. The stem member has an air passage extending in the accommodating member from the open end to the closed end. An electrical conductor is disposed in the air passage to be electrically connected to the cap member when the cap member is mounted on the stem member. A pressure chamber is separated by a partition form the air passage. A tire air introducing passage communicates with the air passage and the tire at a point closer to the open end than the pressure chamber. A bore is formed in the partition to allow a communication of pressure chamber with the introducing passage. A diaphragm expands in the pressure chamber in accordance with pressure lower than a predetermined level flown into the pressure chamber through the introducing passage and the connecting means. An instructing member is secured to the diaphragm for the integral movement and outputs an instruction signal to the cap member through the conductor.
摘要:
A novel method is proposed for the preparation of a calcium silicate powder particularly useful as a filter aid in the filtration of an acidic aqueous liquid by virtue of the extremely high acid resistance of the calcium silicate powder. The inventive method comprises a hydrothermal reaction of a blend of a silica-containing material and calcium oxide or hydroxide in a specified molar ratio under specified reaction conditions to form calcium silicate, which is then subjected to a heat treatment at 800.degree.-1200.degree. C. for 0.5-2 hours. An improvement can be obtained in the clarity of the filtrate obtained by the filtration using the calcium silicate powder prepared by the inventive method as a filter aid when the hydrothermal reaction for the preparation thereof is conducted in an aqueous solution of potassium hydroxide in a specified concentration.

A canister for adsorption of evaporated fuel in an automobile. The canister operates to decrease leakage of the evaporated fuel when the atmosphere temperature rises or the canister is left as it is for a long time. To this end, the canister according to the invention comprises a first container provided in adjacent to an inlet for evaporated fuel and incorporating therein a liquid-phase component adsorbent, a second container provided on the downstream of the first container and on the side or the top of the first container and filled with an adsorbent, and a third container disposed between the second container and an atmosphere port and filled with an adsorbent. Further, the first, second and third container are integrally formed. With such structure, liquid-phase components of the evaporated fuel are collected by the adsorbent in the first container so that a life span of the adsorbent in the second container can be elongated. Further, since the third container is filled with the adsorbent, the evaporated fuel forcibly discharged from the adsorbent of the second container is collected by the adsorbent in the third container when the atmosphere temperature rises or the canister is left for a long time. Therefore, the evaporated fuel can be prevented from being discharged into the atmosphere.

A sheet switch comprises a pair of flexible insulative films, one of which is provided with a plurality of electrodes, resistances connected to the electrodes, respectively, and line patterns for externally connecting the electrodes via the resistances. The other insulative film is also provided with a plurality of second electrodes at positions corresponding to the first electrodes, respectively, and a space is defined between each of the facing electrodes. The line pattern is a laminated structure consisting of an underlayer formed of a low resistance paste and an upper layer formed of a high resistance paste coated over the underlayer. The underlayer formed of a low resistance paste is partially disconnected to define a gap, so that the resistance is formed integrally with the upper layer formed of a high resistance paste at a position corresponding to the gap.
摘要:
A damper for use in controlling the flow rate or direction of a flow of air or fumes flowing out from a room or space or flowing through a ventilation system, including a housing having at least one inlet opening. The housing has a tubular side wall in which are provided a plurality of outlet apertures opened and closed by associated closure members which are adapted to swing to and away from the side wall, preferable inwardly of the housing. The total flow area of the outlet apertures may be extended to a desired degree by increasing the axial length and diameter of the side wall of the housing, whereby the flow resistance and pressure drop across the damper are reduced.
