A shift control device of an automatic transmission causes the transmission to be forcedly shifted to a parking range or a neutral range when the shift ranges indicated by a shift instruction signal produced by a range selector and a current shift range signal produced by a detector are not coincident with each other. After such a forced shift, the shift control device tries to shift the transmission once again as formerly instructed by the range selector, and it is detected once again whether the shift ranges indicated by the current shift range signal and the shift instruction signal coincide with each other.

A power amplifier includes: a distortion compensating circuit that causes a bias circuit to have an output impedance so that a subsequent block bipolar transistor for signal amplification-use has a maximized saturated output power; and a distortion compensating circuit that causes a bias circuit to have an output impedance so that a distortion of an output power of the power amplifier 1 with respect to an input power is canceled by a distortion characteristic of an output power with respect to an input power of the subsequent block bipolar transistor for signal amplification-use which has a maximized saturated output power and a distortion characteristic of an output power with respect to an input power of the preceding block bipolar transistor for signal amplification-use. This makes it possible to provide a power amplifier that allows reduction in saturated output power brought by realization of a highly efficient low-distortion power amplifier.

A process for preparing a ketone, an alcohol and/or a hydroperoxide is provided by reacting a hydrocarbon with molecular oxygen in the presence of a cyclic N-hydroxyimide and a compound of a transition metal, in which an oxygen-containing gas is supplied in a reaction system and at the same time a gas containing 1 to-about 8.59, by volume of oxygen is discharged from the reaction system. This process is excellent in productivity and safety and produces the desired products at a high selectivity.

A public telephone set includes a card controller for reading information recorded in a card and performing conveyance and data processing of the card on the basis of the read information, and a speech controller for performing speech control corresponding to types of cards on the basis of data from the card controller. The card controller includes a card guide port, connected to a first convey path, for receiving plural types of cards and dispensing only a specific type of card, a return port, connected to a second convey path, for dispensing only remaining types of cards which are not dispensed to the card guide port, and a card selector mechanism for switching the cards into the first and second convey paths on the basis of a property inherent to the types of cards inserted into the card guide port, whereby charging processing corresponding to different types of cards is performed.

A public telephone set includes a speech circuit including transmitting and receiving amplifiers for forming a channel loop and two pairs of conductors for respectively connecting a transmitter and a receiver in a handset to the transmitting and receiving amplifiers in the speech circuit. The telephone set further includes an energization circuit having a resistor applied with a power source voltage, a latching relay for switching at least one of the transmitter and the receiver through the conductors to the speech circuit or the energization circuit, and a CPU including an internal timer for monitoring a connecting state of the handset by presence/absence of a current supplied to the energization circuit or a voltage appearing in the energization circuit when the latching relay switches at least one of the transmitter and the receiver to the energization circuit.

In a method of rolling metal for producing a metal plate or a metal sheet having a desired range of thickness through a sequence of rolling passes, variations in the deformation resistance of the metal along the longitudinal direction of the metal are detected, variations in deformation resistance and the resulting variations in rolling force in the finishing pass are estimated, and the rolling for obtaining the necessary thickness of the metal at the entrance of the finishing pass is carried out under a combination of a feedback automatic gauge control process and feed-forward automatic gauge control process, whereby variations in the rolling force are cancelled even if the metal which is to be rolled has skid marks thereon.

Provided is an endoscopic duct cleaning tool which uses elastic porous members to prevent the inside of a duct of an endoscope from being damaged, and which can firmly fix the elastic porous members to a core wire and secure a sufficient thickness in each of the elastic porous members.This endoscopic duct cleaning tool 1 is inserted into a duct 53 of an endoscope 50 to clean the duct 53. The endoscopic duct device 1 includes a core wire 10 consisting of a stranded wire, plural cylindrical elastic porous members 20 disposed at certain intervals and at certain places in an axial direction of the core wire 10 so as to cover an outer circumference of the core wire 10 directly, and resin tubes 30 covering outer circumferences of portions of the core wire 10 which are not covered with the elastic porous members 20. An outer diameter of each of the resin tubes 30 is formed to be larger than an inner diameter of each of the elastic porous members 20. A frontmost end tube 31 and a basemost end tube 32 disposed in a frontmost end portion and a basemost end portion of the core wire 10 respectively are fixedly attached to the core wire 10.
