    Abstract: A constant-temperature type crystal oscillator includes: a crystal unit that is installed on one principal surface of a circuit substrate, and chip resistors, which function as heating elements, and which are installed on the other principal surface of the circuit substrate so as to face a principal surface of the crystal unit, the chip resistors heating up the crystal unit to keep an operational temperature of the crystal unit constant. A heating metal film facing the principal surface of the crystal unit is provided on the one principal surface of the circuit substrate. A heat conducting material is interposed between the principal surface of the crystal unit and the heating metal film to perform thermal coupling therebetween. The heating metal film is thermally coupled to electrode terminals of the chip resistors via a plurality of electrode through holes.

    Abstract: A resist 7 of a predetermined thickness is formed on a printed circuit board 1 except electrode-opposing portions 1a (FIG. 1A), and a silk screen printed layer 9 of a predetermined thickness is formed on the resist 7 (FIG. 1B). Thereafter, a concave portion 2b of a film capacitor 2 is bonded to the silk screen printed layer 9 by an adhesive double coated tape 6 of a predetermined thickness in such a manner that electrode portions 2a of the film capacitor 2 are opposed respectively to the electrode-opposing portions 1a of the printed circuit board 1 (FIG. 1D). Here, the sum of the thicknesses of the resist 7, silk screen printed layer 9 and adhesive double coated tape 6 is not smaller than a concave-convex height difference L1 of the film capacitor 2, and with this arrangement the electrode portions 2a of the film capacitor 2 are prevented from interfering with the printed circuit board 1. An adhesive is not used, and therefore a problem with respect to environment-affecting substances is solved, and at the same time difficulty involved in the control of a bonding strength can be overcome.

    Abstract: An oscillator assembly includes an oscillator circuit that is configured to generate a frequency signal. A temperature compensation circuit is in communication with the oscillator circuit and adapted to adjust the frequency signal in response to changes in temperature. The oscillator and temperature compensation circuits are located within an oven. A heater and a temperature sensor in communication with the heater are also both located in the oven. The temperature sensor is adapted to directly control the heater in response to changes in temperature. In one embodiment, the oscillator components are mounted to a ball grid array substrate which, in turn, is mounted on a printed circuit board. In this embodiment, a resonator overlies the ball grid array substrate and a lid covers and defines an oven and enclosure for the resonator and the ball grid array substrate. The oscillator and temperature compensation circuit are defined on the ball grid array substrate.

    Abstract: A secondary battery or capacitor fitted with terminals and occupies less area on a packaging substrate. Either one of the positive and negative terminals is mounted within the outer surface of the secondary battery or capacitor. This reduces the area occupied by the secondary battery or capacitor fitted with terminals on the substrate. At least one step is formed on the terminal positioned opposite to the substrate. This prevents electrical shorting between the positive electrode can and the negative terminal.
