IPC: F16H61/16
Filed: 1990-11-28
Abstract: PURPOSE:To prevent frequent generation of a busy shift and a speed change shock by commanding a downshift to a one-step lower speed change shift from a specific speed change shift by judging the downshift and a two-step lower downshift only at the time of satisfying a predetermined condition after the lapse of a timer.

Constitution is provided so as to output a downshift command to the lower speed change shift only when a predetermined condition is satisfied after the lapse of the timer. As a result, for instance, when an accelerator is stepped in by intending a downshift by one step lower by a driver, the condition after this predetermined time is not satisfied, so that an automatic transmission is stopped in a speed change shift lowered by one step from the specific speed change shift. Further, when the predetermined condition is satisfied, the downshift to the lower speed change shift can be performed.

Title: Thick film capacitor
Inventor: TAKADA KOZO
IPC: H01G4/255
Filed: 1989-12-19
Abstract: PURPOSE:To obtain an excellent thick film capacitor on which capacitance value can be finely adjusted continuously by a method wherein the upper electrode of the thick film capacitor is formed in disc-like shape having a circular aperture in the center part. CONSTITUTION:A thick film capacitor is set in a laser trimming device, and a groove 17 is cut by moving a laser beam from the center part of an upper electrode part 13 to the direction of radiation. Then, a groove 18 is cut in the direction of radiation at an angle of theta from the cut groove 17, and the upper electrode 13 is out off in sector form. Consequently, as the section surrounded by the cut grooves 17 and 18 is electrically isolated from the other section of the upper electrode part 13, electrostatic capacitance is reduced by the amount of the reduced area. Thus, as the area cut off from the upper electrode 13 is determined by the angle theta formed by the cut grooves 17 and 18, the value of capacitance can be finely adjusted continuously in a simple manner by properly changing the angle theta.
