摘要： Matrix element calculation carried out efficiently without the overhead of communication between a host computer and processor elements even in parallel calculation utilizing a low-cost communication device and multiple processor elements having memories of a small capacity. In a method for calculating molecular orbitals, for example, all elements F(I, J) of a Fock matrix are calculated where an outermost loop is a loop associated with combinations (RT) of contracted shell R and contracted shell T which satisfy relationships R≦Nshell and T≦R. A second loop is a loop associated with contracted shell S, and a third loop is a loop associated with contracted shell U. Alternatively, the second loop is a loop associated with the contracted shell U, and the third loop is a loop associated with the contracted shell S. The value of S ranges from 1 to R, and the value of U ranges from 1 to R. Calculation of predetermined electron repulsion integrals and calculation of a predetermined part of Fock matrix elements utilizing the result of the calculation is carried out inside the third loop.

摘要： In a crystal unit suitable for use in a thermostat oven, a first and a second excitation electrode are disposed on a first and a second surface of a crystal blank. A first and a second connection are disposed on the second surface as connections formed by applying a fillet of a mixture of a low-melting glass and a metal filler, and melting the fillet by heating. A third connection is disposed on a peripheral edge of the crystal blank to extend over both surfaces. A lead of the first excitation electrode is directly connected to the third connection, while a lead of the second excitation electrode is connected to the first connection through a vapor-deposited metal thin film. The second and third connections are connected to each other through a vapor-deposited metal thin film. The first and second connections are secured to a pair of holding members by brazing.

摘要： A quartz crystal unit with favorable frequency variation characteristics in response to changes in temperature and changes over time. A pair of lead wires provided perpendicularly to a base and a pair of supporters supported on the pair of lead wires are used for holding and electrically connecting a quartz blank at opposite points on the periphery thereof to which leading electrodes extend. The orientation of a line connecting holding points matches an axis on which stress sensitivity of the quarts blank exhibits the least value. A line connecting both supporting points for the supporters by the lead wires is disposed in a skew position with respect to another line connecting both holding points for the quartz blank. When the quartz blank is AT cut, an angle formed between these lines in the skew relationship is preferably set to approximately 30 degrees.
