    Abstract: A controller (61) calculates a transient target speed ratio based on a final speed ratio set according to a vehicle running condition and second order delay time constant gains (75, S99), and control a speed ratio of a continuously variable transmission to the transient target speed ratio via an actuator (4) (87, S103). The controller (61) also calculates the deviation between the final target speed ratio and transient target speed ratio (74, S95), and determines the second order delay time constant gains based on the deviation (74, S98). Preferably, the gains are determined so that the response rate is slower the larger the deviation (74, S134, S135, S136, S137, S139, S140, S141).

    Abstract: In a vehicle automatic transmission, a controller (61) feedback controls a speed ratio command signal by proportional/integral/differential (PID) control so as to minimize a deviation between a transient target speed ratio and a real speed ratio. When a difference between the command signal and that of the preceding control cycle is larger than a predetermined value, the controller (61) prohibits the increase of an integral correction amount of the PID control in the next control cycle. In this way, continuous increase of the feedback correction amount while the transmission can not follow the command signal is suppressed.

    Abstract: A method for detecting a focal point uses an optical system which includes a laser diode light source, a beam-splitter prism having three surfaces with one surface perpendicular to luminous flux emanating from a recording medium and another surface inclined relative to the first, an objective lens between the prism and the recording medium, a photodetector, and an apparatus capable of moving the objective lens perpendicular to the recording surface. The method using this apparatus includes the steps of placing the prism so that the incident angle of the flux through the objective lens is less than the emergent angle of the flux from the prism to the photodetector, detecting the intensity of the light, and driving the objective lens in response to an electrical signal.

    Abstract: A novel high frequency heating apparatus for detecting the internal temperature of an object contained in a heating chamber and controlling the heating thereof is disclosed, in which the temperature change of the object is picked up as a change of the resistance value of a thermistor. The resistance change is converted into a change of the oscillation frequency of an oscillator and transmitted with the ultrasonic wave as a medium. The power supply for the transmitter circuit is provided in such a manner that the high frequency filled in the heating chamber for heating the object is received by an antenna and rectified by a diode. At the receiving end, this ultrasonic wave is picked up as a temperature signal of the object, and processed by a microcomputer, so that the temperature of the object is detected for heating control.

    Abstract: A high frequency energy apparatus is provided in which high frequency energy is supplied into a heating chamber containing an object to be heated for heating the same. A temperature sensor unit senses either the temperature of air within the heating chamber or the temperature of air flowing out of the heating chamber and a memory unit memorizes a sensed air temperature. When a difference between the air temperature sensed and the memorized temperature reaches a preset value, the amount of supply of the high frequency energy is varied. The preset value is varied with the heating time for heating the object more properly.
