Filed: 1993-08-26
Abstract: PURPOSE:To obtain an ultrasonic motor requiring no large vibration return route or energy absorber by installing an attenuating portion at the end of a traveling direction of a traveling vibration wave of an elastic body. CONSTITUTION:An ultrasonic motor comprises an elastic body 1, electric- mechanical conversion element 2, and a moving body 3; an elastic body 1 comprises an elastic portion la and attenuating portions 1b and 1c located at both the ends; the elastic body 1a is a bar-shaped body with a square cross section; and the attenuating portions 1b and 1c have a horn shape which gradually becomes slender toward the tip. And the ultrasonic motor is supported by the tips at both the end portions of the attenuating portions 1b and 1c; the electric-mechanical conversion element 2 is vibrated by the application of a high frequency voltage and generates a traveling vibration wave in the elastic body 1, and the moving body 3 pressing and contacting to the elastic body 1 is driven by a traveling vibration wave. Its drive range is between the right end position in a longitudinal direction of the elastic portion and the position corresponding to the right end of the electric-mechanical conversion element 2. In consequence, an ultrasonic motor requiring no large vibration return route or energy absorber can be obtained.

Inventor: ARAKAWA NORIYUKI
IPC: F16L21/08
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To execute a work without needing special arts, such as welding, and being influenced by weather, to block separation of tubular bodies from each other, and besides to be manufactured at a low cost. SOLUTION: A spigot 3 is formed at one pipe 1, and a socket 4 is formed at the end part of the other pipe 2. With the spigot 3 inserted in the socket 4, a bolt 5 is extended from the sides of the pipes 1 and 2 through the socket 4 and the spigot 3 part to interconnect the pipes 1 and 2. This constitution simply interconnects the pipes 1 and 2 not only without a need for special arts, such as welding, but also without being influenced by weather, and besides manufactures the connection structure of a tubular body at a low cost. Further, even when, in a foundation pile, a force is exerted in the pipe axial dirction, the pipes 1 and 2 are not separated from each other at a connection part therebetween, whereby reliability is improved.

Title: Flow rate control method
Inventor: KAWAI MINORU
IPC: G05D7/00
Filed: 1984-10-09
Abstract: PURPOSE:To make it possible to control a flow rate with high responsiveness and with less loss of energy by controlling the rotation speed of a flow delivery means according to the necessary volume. CONSTITUTION:When a setting signal Sf is step by step reduced at time point t1, a flow rate adjuster 5 makes control calculation to meet with the signal Sf and temporarily reduce the opening angle of a flow control valve 4 diminishing operational output SM. A valve opening adjuster 10 issues a setting signal for reducing the rotation speed of a blower 1 to a rotation adjuster 11. The adjuster 11 makes an output to rotation adjusting circuit 9 so that the rotation of a motor 7 may coincide with the setting signal. As a result, a flow volume signal Vf tends to become small due to the reduction of the blower 1 and opening of the valve 4, but the adjuster operates so that the signal Vf may coincide with the signal Sf, the opening of the valve 4 eventually opens until the angle which coincide with the initial setting signal Sv.

Title: Power supply device
Inventor: YOSHINO SUSUMU
IPC: G06F1/28
Filed: 1986-09-08
Abstract: PURPOSE:To ensure a proper countermeasure when a service interruption is recovered by using the output of a holding means which compares the battery voltage for backup with the reference voltage and holds the result of this comparison. CONSTITUTION:The voltage of a battery BA is divided by resistances R2 and R3 and supplied to a comparator 3 that defines the Zener voltage of a Zener diode as the reference voltage. Then the comparator 3 produces output when the voltage of the BA drops and the voltage produced at the joint between both resistances R2 and R3 drops less than the reference voltage, i.e., down to a limit level where the normal working is impossible with a load. While a relay LR is set under a self-support state by the output of a drive circuit 4 to which the output the comparator 3 is given. The relay LR is never restored before receiving a restoring current. Thus it is possible to prevent a relative device from working by the output of a contact lr of the LR even though a main power supply is restored after the storage of a memory device serving as a load is erased. In such a way, a proper countermeasure is secured when the service interruption is recovered.

Title: Data communication device
Inventor: KOMATSU KAZUYUKI
IPC: H04M11/00
Filed: 1986-09-09
Abstract: PURPOSE:To prevent unnecessary commercial messages from being received by registering opposite telephone numbers from which data is not received by rejection and rejecting data reception when there is incoming from a registered telephone number. CONSTITUTION:When a facsimile reception state is entered, a control part 26 recognizes the telephone number of the opposite side with a signal (e.g. TSI signal) sent out of the opposite-side facsimile equipment and checks whether or not the telephone number is registered in a rejected telephone number storage circuit 22. When it is registered, a DCN signal is sent out in response to an NSS/TSI/DCS signal sent out of the opposite facsimile equipment to reject facsimile reception. The opposite telephone number from which an unnecessary commercial message is sent is registered previously to reject incoming from the same opposite subscriber. Consequently, recording paper is not wasted and a failure in receiving important information owing to the busy state of a line when it is necessary is eliminated.
