摘要： PURPOSE:To improve the property and productivity of an electromagnetic relay for which a moving contact spring and a fixed outside connecting terminal linked thereto are at least joined by ensuring and stabilizing joint in a joint area, even if it is small between the moving contact spring and the outside connecting terminal. CONSTITUTION:A electromagnetic relay is so constructed that a moving contact spring and a fixed outside connecting terminal linked thereto are at least joined with the free end of a tongue as a joint area protruded from the single side at the longitudinal middle of the moving contact spring. For the electromagnetic relay, a positioning means which contains a slit groove 22a'' and a protrusion 21a' fitted to the slit groove 22a'' is provided in the joint area between moving contact springs 22a-1, 22a-2 and the outside connecting terminal 21a.

摘要： PURPOSE:To suppress deformation, etc., of covers due to the heat at the time of mounting and improve the productivity by making the external connection terminal part visible with eyes and thickening the thickness of the covers without widening the mounting surface area of a realy on a circuit substrate. CONSTITUTION:The external face of circumferential wall of a cover 6 to be mounted on a relay main body 2 is so made as to locate near the region formed in the case the tips of respective external connection terminals 22a-1', 22b-1', 22b-2' of the main body 2 are connected. Also, in the region corresponding to each external connection terminal, a connection region for at least a circuit substrate 4 of each external connection terminal is composed while a recessed part which can be observed with eyes from right above or obliquely above outside is formed. As a result, the thickness of the circumferential wall of the cover 6 except the regions corresponding to the external connection terminals is made thick in the region of the external connection installation, that is, the range of the region where connection electrodes of the substrate 4 are formed. Consequently, deformation and strain and damage of the cover due to the heat at the time of being mounted on the substrate 4 are prevented and the productivity is improved.

摘要： PURPOSE:To obtain a sufficient noise reduction effect by means of a new electromagnetic relay of a size equal to that of a normal electromagnetic relay by sealing a plurality of contact springs each provided with a contact and a driving unit containing an electromagnet which is formed by winding a coil around an iron core and an armature in an airtightly sealable console together with liquid. CONSTITUTION:A plurality of contact springs 3 each provided with a contact 31 and a driving unit 2 containing an electromagnet 23 which is formed by winding a coil 22 around an iron core 21 and an armature 24 are sealed in an airtightly sealable console 1 together with liquid 4. Thus, operation noise which propagates in the air and is emitted outside is eliminated and also operation noise propagating via reed terminals or the like can be suppressed. Thus a sufficient noise reduction effect can be obtained with a size of a new electromagnetic relay equal to that of a normal electromagnetic relay so that an electromagnetic relay whose number of parts and number of assembling man- hours are equivalent to those of the normal electromagnetic relay can be obtained.

摘要： PURPOSE:To always prevent the generation of parallax by allowing a touch panel to change its relative position to a display panel while interlocking with a change in the tilt angle of a display panel and automataically correcting the parallax generated between both the panels. CONSTITUTION:When a tilt angle is changed from delta to delta' and an visual angle is changed from 0 to theta, theta=delta-delta' is formed and the parallax S is expressed by S=ltantheta=ltan(delta-delta'). Where l is an interval between an item display part 20 and a touch input electrode part 10. When the position of the touch pane 11 is relatively changed from the display panel 2 only by S correspondingly to the change of the tilt angle from delta to delta', e.g. interlocking with the change, only the parallax is automatically corrected. Consequently, the generation of parallax can always be prevented.

摘要： PURPOSE:To always obtain correct ejection state by driving a gear motor at ejection and turning off the gear motor while confirming the on-state of a rotary position detection means after the off-state of a medium loading state detection means is detected. CONSTITUTION:The gear motor 9 is driven at the ejection, after the off-state of the medium loading state detection means 13 is detected, the on-state of a rotary position detection means 12 is confirmed to turn off the gear motor 9. If the rotary position detection means 12 is in the off-state at application of power, the gear motor 9 is driven and after the on-state of the means is confirmed, the gear motor 9 is turned off. Thus, automatic ejection is always conducted and the medium is loaded even if the power is shut down.

摘要： PURPOSE:To attain sure and stable read/write to/from a track of the maximum storage density by abutting the 1st magnetic head supported fixedly on a storage area including a track having the highest storage density and abutting the 2nd magnetic head movable via a floppy disc to be mated to the magnetic head on the storage area. CONSTITUTION:A carriage 1 movable horizontally by motor drive supports upward the magnetic head 4 via a gimbal spring 3. A carriage 7 supporting downward the magnetic head 6 via a fixed plate 21 has one end of a plate spring 8 at the lower face of the right end. The magnetic head 6 giving/receiving (R/W) information to and from the track having the maximum storage density is fixed to the carriage 7 and the magnetic head 4 opposing to the magnetic head 6 is supported rockably via the gimbal spring 3, then the read/write to the maximum density track is ensured stably and the reliability of the magnetic head support mechanism is improved.

摘要： PURPOSE:To realize a stable dropping of a storing case by sliding an ejecting plate in a decelerated condition by an operation of an impact relieving means during lowering the accommodating case. CONSTITUTION:When a disk cassette 70 is inserted into a storing case 20 through an inserting hole 14, a slide cover is opened in a process of an insertion. When after an inserting end of the disk cassette 70 abuts on a rear end of the storing case 20, the cassette 70 is further inserted, the case 20 slides in a direction shown by an arrow (a). This slide operation is done by sliding a roller section 26 of a roller 24 on a horizontal groove of a groove 61. At this time, the slide operation of an ejecting plate 20 induces a pinion member 41 to rotate in a direction shown by an arrow (d) by a rack 32. While the ejecting plate receives a tension of a spring 63, a 'slow' (because a rotation of the pinion member 41 is retarded) slide is realized.
