A technical system is broken down into a plurality of subsystems, each of which is allocated a time-dependent distribution function which describes the probability of failure of the respective subsystem. The logic responsively provides a supply pump speed control signal, according to a predetermined target oil pressure value selected to correspond to the data contained in the signals. When the driver unit and the clincher unit are traveled from an initial position to a skewed binding position, the 0 degree claw portion 119 impinges on the stopper pin and the driver unit and the clincher unit are rotated to the 45 degree rotated position to fix. The middle-breakdown-voltage insulating film is formed so as to be thinner than the high-breakdown-voltage insulating film. The techniques include obtaining customer information, obtaining one or more service characteristics for each of the one or more services, and using the customer information and the one or more service characteristics to schedule the one or more services. A PN junction formed on a semiconductor substrate serves as the thermosensitive portion, and it is used to provide for a compact infrared sensing element with high performance at low cost.
