摘要： PURPOSE:To provide a surface mount component having a terminal form wherein a complicated manufacturing process like resin molding is unnecessary, and automatic mounting suction also is stably enabled, in the case of a surface mount component which is used in various kinds of electronic apparatus. CONSTITUTION:At least one of outer terminals 3 has a terminal length D greater than or equal to 1/2 of the long side dimension L of a columunar electronic component element 1. A planar part 3a is formed on the upper surface of a cylindrical resistor. By this constitution, a form having a suction plane necessary for mounting can be realized.

摘要： PURPOSE:To obtain desired sound quality by varying the level of intermediate and high frequency range freely by changing the direction of a tweeter cabinet. CONSTITUTION:On the hard board 2 of a rear tray, a speaker grille 3 is arranged, a woofer speaker 4 is fixed to the speaker grille 3, and a tweeter cabinet 6 which has an incorporated tweeter speaker 5 is stored in a recessed part 7 provided to the speaker grille 3. A transfer mechanism consisting of a motor 8, a decelerating mechanism 9, a spur gear 10, a slip mechanism 11, etc., and changing the direction of the cabinet 6 is provided inside of the speaker grille 3. Under the control of a control switch part provided at a distance from a speaker device the direction of the cabinet 6 is changed to control the level of intermediate and high frequency range freely, thus desired sound quality is obtd.

摘要： PURPOSE:To enable an accurate temperature control to be done by a method wherein an AC current or a pulse current is caused to flow through a glow plug, the AC impedance thereof is measured and when it is detected that the temperature of the glow plug reaches a predetermined value, the supply of power to the glow plug is controlled. CONSTITUTION:When an ignition switch 11 goes ON, a relay 9 and a glow lamp 10 go ON whereupon a relay contact 2 is closed so that power is supplied to the glow plug 4 through a choke coil 3 and the glow plug becomes red hot. The AC signal from an AC current or a pulse generator 5 is supplied to the junction of the choke coil 3 and the glow plug 4 through a capacitor C1 and a resistor R. When the resistance of the glow plug 4 reaches a predetermined value, that is, the temperature of the glow plug 4 reaches a predetermined value, signals from an amplifier 6 and a voltage comparator 7 are transmitted to a relay controller 8 to thereby cause both the relay 9 and the glow lamp to go OFF.

摘要： PURPOSE:To eliminate looseness in fitting by a method wherein the radio is held by pinching it through leaf springs provided on the adaptor of the radio in case the car radio is inserted into and fitted to the adaptor after the radio adaptor, formed by bending a steel strapping into the shape of a gate, is inserted into the opening of a front panel for mounting the radio. CONSTITUTION:The radio adaptor 5 is inserted into the opening of the front panel 2 for mounting the radio provided on an instrument panel mounted in a cabin. This adaptor 5 is formed by bending the steel strapping into the shape of a gate and pinching protrusions 7, 7', projecting horizontally and inwardly from the upper and lower rims of both of the side plates 5b, are provided along substantially whole lengths of the side plates. Protruded parts 7a and recessed parts 7b are formed at the central part of the upper and lower protrusions 7, 7' and convex leaf springs 16 are provided below the protruded parts 7a. Such adaptor 5 is inserted into and fixed to the opening of the front panel, thereafter, the car radio 4 is inserted into and fitted to the adaptor 5 and is pinched by the leaf springs 16 thereby eliminating the looseness between the adaptor 5 and the radio 4.
