摘要： PURPOSE: To make a relay small in size, thin in thickness, multiply its channels, and accelerate relay switching speed. CONSTITUTION: With respect to the form aerotropic magnet 51 of a lever contact substrate 50, magnetic cores 62 and 72 on the side of an electromagnet substrate 60 or 70 are disposed face-to-face to each other, and furthermore, the contact output terminals 52, 53, 54 and 55 of the lever contact substrate 50 are disposed face-to-face to one another. By this constitution, when the form aerotropic magnet 51 is attracted by the magnetic cores 62 and 72, the contact output terminals 52, 53, 54 and 55 are energized via energizing contacts 69 and 79. Not only a former constitution can be eliminated, in which each movable contact section is operated by the electromagnetic action of an electromagnet, and each movable contact section is returned by the energizing force of a restoring spring, but also a first movable contact and a second movable contact can thereby be made light in weight. Since movement can be made quick when a relay is in operation, the relay can be made small in size and thin in thickness, its channels can be multiplied, and its realy switching speed can also be accelerated.

摘要： PURPOSE:To provide an image sensor which is suitable for miniaturization and weight reduction and exactly reads information by using the end face of a substrate as a working part. CONSTITUTION:A first electrode film 31 conductive to a common electrode 21 provided on one face of an insulating substrate 20 is provided on the end face of the insulating substrate 20. A second electrode film 33 conductive to an individual electrode 22 provided on the other face of the insulating substrate 20 is provided on the first electrode film 31 through a photoelectric conversion film 32. An image sensor 10 having this light receiving part 30 on the end face is arranged perpendicularly or obliquely to a read document 60, and the light emitted from a light emitting part 40 is reflected by the surface of the document 60 and is made incident on the light receiving part 30. Consequently, the length in the carrying direction of the document 60 brought into contact with the image sensor 10 is short, and the contact state of the document 60 is stabilized to improve the read precision. Since the area occupied by the image sensor 10 in the carrying direction of the document 60 is considerably reduced, a device like a facsimile in which the image sensor 10 is built is miniaturized.

摘要： PURPOSE:To obtain a thermal head little affected by thermal stress and excellent in thermal responsiveness and printing performance by forming the heating body thin film divided into a plurality of dot areas on the end face of a base plate with a highly accurate shape characteristic and arranged structure. CONSTITUTION:After forming conductive copper patterns and thin copper films 20 and 30 for use on a common electrode on both the faces of an insulated base plate 10, a groove 12 is formed in the end face of the base plate, which is then divided into a plurality of dot areas 13. A heating body thin film 40 is deposited on the dot area 13 by sputtering. To form the heating body thin film 40 after the formation of the groove 12, this film 40 is so shaped as to conform exactly with the surface of the dot area 13 and each adjacent dot is separated by the groove. The adhesion to the end face of the base plate is also satisfactory. For this reason, a highly clear printed surface is obtained stably over an extended period of time.

摘要： PURPOSE:To provide a thermal head for serial thermal printer which allows a heating body alone to be pressed into a proper contact with a platen, has a satisfactory thermal responsiveness with a small electric power and produces no adverse effect such as causing the parts other than the heating body to contact with an ink ribbon or paper. CONSTITUTION:Conductive patterns 5 and 6 are formed both or either side of a nearly L-shaped base plate 2 consisting of an insulating and heat resisting synthetic resin. A heating body 3 for use in printing having a wear resisting protective membrane 4 is formed on the end face or projecting curved face of the resin base plate 2, connected to the conductive patterns 5 and 6 and fixedly layered on a reinforcing and heat releasing frame 9. As a result, since the heating body 3 alone comes in contact with an ink ribbon 8 and paper 7 and contact pressure between a thermal head 1 and a platen can be reduced, thereby avoiding impairment to the ink ribbon 8 or the paper 7 and printing contamination.

摘要： PURPOSE:To obtain clear EL display having high visibility without requiring, masking process. CONSTITUTION:A pair of electrically conductive layers 13 and 14 continuing to both surfaces of a substrate through holes 11 and 12 are arranged on an insualting substrate 10. An insulating layer 21, an emission layer 22 and an electrically conductive transparent film 23 are laminated in order on a pattern electrode 13a formed of one electrically conductive layer 13. Electrode terminals of the pattern electrode 13a and the electrically conductive transparent film 23 are taken out respectively from the electrically conductive layers 13 and 14 on the reverse side of the insulating substrate 10 through the through holes 11 and 12. The pattern electrode 13a has the same shape with a segment of a display pattern. Since a cut sheet, a colored sheet, a directional film and so on are superposed on the electrically conductive transparent film 23, visibility can be improved. A improved visibility layer can be also formed by applying pattern printing to the emission layer by means of ink containing fluorescent pigment and so on.

摘要： PURPOSE:To form a heat generating thin film having dot pattern with high density on an end face of a substrate so as to print clearly by superposing two insulating substrates. CONSTITUTION:On both faces of insulating substrates 10 and 14, conductive copper patterns 20 and common electrode copper thin films 30 are formed respectively, which are connected by a heat generating thin film 40 made by forming the conductive copper pattern 20 and the common electrode copper thin film 30 on end faces of the insulating substrates 10 and 14. The heat generating body 40 is divided into a plurality of dot partitions at a predetermined pitch. The insulating substrates 10 and 14 are superposed in a state that respective dot partitions are deviated from each other by a half pitch. The superposed insulating substrates 10 and 14 are interposed by radiating bodies 42 and 43 from both sides. Since a thermal head is constituted of one set of 2 sheets, the pitch of the dot pattern of the heat generating body 40 to be formed on individual insulating substrates 10 and 14 can be high, so that dot pattern with high density can be formed and manufacture thereof will be easy.

摘要： PURPOSE:To provide an EL display unit capable of being manufactured with a high yield, easily having a large screen, and having excellent reliability. CONSTITUTION:A light emitting element 40 is formed on the end face of an insulating base 10, an individual electrode 20 and a common electrode 30 connected to the metal electrode and transparent electrode of the light emitting element 40 respectively are formed on both faces of the insulating base 10 faced to the end face. Multiple insulating bases 10 are arranged face to face, and an X-Y dot matrix arranged with multiple light emitting elements 40 (picture elements) in the X-direction and the Y-direction is formed. Individual electrodes 20 of the insulating bases 10 are conducted by a lead 50 inserted into through holes formed on the insulating bases 10. The yield is sharply improved as compared with the case that the light emitting element 40 is formed on the plane of the insulating base 10. The size of a screen can be freely set by the number of arranged insulating bases 10.

摘要： PURPOSE:To provide a thermal head which reduces an influence exercised owing to a thermal strain and has excellent thermal response by a method wherein a base sheet is curved and a heat generating body serving as a working surface is positioned at a top. CONSTITUTION:A base sheet 1 on the one surface side of which a conduction copper pattern 2, a common electrode copper film 3, and a heat generating body 4 are formed is folded so that the heat generating body 4 is positioned at a top, and supported from the rear by means of a support 8. With this state, a heat-sensitive sheet is caused to pass as the sheet is brought into contact with the heat generating body to perform printing. A slight gap is formed in a position, where the heat generating body 4 is formed, between the base sheet 1 and the support 8 to form a heat insulating layer.
