Title: Ultrasonic motor
Inventor: TAKAGI TADAO
IPC: H02N2/00
Filed: 1994-02-09
Abstract: PURPOSE:To prevent an unstable movement in an ultrasonic motor, by using a given material of a first frictional contacted face, and specifying a coefficient of friction between contacted faces of a stator and a rotor. CONSTITUTION:When a coefficient of friction between a stator 3 and a rotor 2 is 0.34, a hysteresis phenomenon occurs in a resonance characteristic curve, which represents a relation of a driving output of an ultrasonic motor 1 to a frequency of a driving power supply. In this case, the ultrasonic motor can not be driven stably. On condition that the coefficient of friction between the rotor 3 and stator 2 is below 0.25, the hysteresis phenomenon doesn't occur in the ultrasonic motor 1. When the coefficient is larger than 0.34, the hysteresis phenomenon is intensified. Consequently, the material of the stator 2 is so selected that the coefficient of friction between the rotor 3 and stator 2 becomes below 0.34 adequately. Then, the hysteresis phenomenon doesn't occur in the resonance characteristic operation, and the ultrasonic motor can be driven more stably.

Filed: 1989-02-17
Abstract: PURPOSE:To prevent smear of a treatment room and an object to be treated within a treatment room by setting the amount of supply of treatment gas at least at a timing for starting supply of treatment gas to a smaller value than needed. CONSTITUTION:One part of an etching gas is introduced and discharged into a discharge pipe 22 through a bypass pipe 20 since a valve D21 of the bypass pipe 20 is open. Thus, the etching gas introduced by a gas-introducing pipe 8 is divided into gas flow toward a treatment room 1 and that toward a discharge pipe 22 through the bypass pipe 20, thus reducing flow of gas into the treatment room 1. Therefore, pressure fluctuation within the treatment room 1 is reduced and particles adhered to the inside of the treatment room 1 and pipes, etc., are not scattered, and the inside of the treatment room 1 and a wafer 5 installed within the treatment room 1 are not polluted by the particles.

Title: Faulty node checking method for ring network
Inventor: ISHIDO KAZUO
IPC: H04L12/42
Filed: 1991-02-08
Abstract: PURPOSE:To reduce the number of bits in the check area of a check frame, which is used to detect trouble of nodes connected to a ring type network, independently of the number of nodes. CONSTITUTION:When contents of the check frame are the node number of a node one above its own node, this node judges the node one above its own node to be normal and rewrites contents of the check frame with the its own node number to send the check frame to a transmission line. If contents of the check frame are not the node number of the node one above its own node, its own node judges the node one above itself to be faulty and records the faulty node number or reports it to a master node and writes its own node number in a specific area.
