Title: Ultrasonic probe and thickness measuring device of clad material
Inventor: NAKAO YOSHIYUKI
IPC: G01N29/24
Filed: 1988-03-25
Abstract: PURPOSE:To obtain an ultrasonic probe in a simple structure which projects transversal ultrasonic waves perpendicularly to the surface of a test piece to be measured, by integrally connecting a member comprising a propagating unit and a sound wave converting unit which are in contact with each other by a predetermined inclination angle, to a vibrator generating longitudinal ultrasonic waves. CONSTITUTION:A vibrator 10 is mounted within a mounting hole 20 formed in a propagating unit 2. A tightly-contacting surface 21 is formed at an end surface of the propagating unit 2 with an inclination of a predetermined angle alpha. A sound wave converting unit 3 is provided with two surfaces, namely, an oscillating surface 30 and a tightly-contacting surface 31 which are inclined a predetermined angle beta each other. The tightly-contacting surface 31 is in tight contact with the surface 21 of the propagating unit 2. Consequently, longitudinal ultrasonic waves generated by the vibrator 10 pass through the surfaces 21 and 31 to enter the sound wave converting unit. In the sound wave converting unit 3, the longitudinal ultrasonic waves are converted to transversal ultrasonic waves. Thereafter, the ultrasonic waves are incident upon a test piece T to be measured from the other surface, that is, the oscillating surface 30 in a vertical direction. By using this probe 1 in combination with a conventional longitudinal ultrasonic wave probe, the thickness of a clad material can be positively measured.

Title: Method for straightening bends of member
Inventor: TOIKETA HIDEO
IPC: B21D3/10
Filed: 1989-03-24
Abstract: PURPOSE:To automatically obtain an optimum straightened value by correcting the corrected amount when the amount of bend of a member straightened in accordance with a certain straightening amount is beyond the tolerance. CONSTITUTION:For example, in the manufacturing process of a power window motor for the automobile, after a worm 1a is formed on a rotor shaft 1 the run-out is measured by a run-out straightening device 2, a table part corresponding to the amount of straightening in a straightening course is corrected concerning the part other than the tolerance and the member is corrected again by the amount of straightening after the correction. Consequently, when the member 1 having the same bend is corrected again, the optimum amount of straightening can be obtained automatically. Further, since an operator need not change the setting for the amount of straightening at every change of a lot, the efficiency in straightening the bend can be improved.

Title: Audio amplification device
Inventor: WASSINK DERK JAN CHRIS
IPC: H03G1/00
Filed: 1994-03-17
Abstract: PURPOSE: To obtain an audio amplifier which can remarkably reduce the overload to an output amplifying stage and from which the alteration of the set volume of a user can be recognized clearly. CONSTITUTION: An audio amplifier has a first amplifying stage 2 which acts on the signal intensity of audio signals inputted through an input terminal 1 with respect to at least part of the frequency spectrum of the signals. An output amplifying stage 3 amplifies the signals acted by means of the first amplifying stage 2. A detecting means incorporated in the output amplifying stage 3 detects the overload to the stage 3. When the overload indicated by the detect signal of the detecting means exceeds a prescribed limit, a control circuit 5 adjusts the action of the amplifying stage 2 in response to the detect signal. Since the above-mentioned limit varies depending upon the degree of already made adjustment, the degree of the overload corresponding to the limit increases when the degree of adjustment increases.

Abstract: PURPOSE:To obtain a ceramic package type semiconductor device having no defective flow and defective sink mark and having high airtightness by forming a through-hole shaped to at least one of a ceramic substrate and a ceramic cap and a cover member mounted while closing the through hole after the ceramic cap is sealed. CONSTITUTION:An internal chamber 23 is shaped between a semiconductor element 11 fixed to a ceramic substrate 12 and a ceramic cap 19 and a gas in the internal chamber 23 expands on heat treatment, but the expanding gas is diffused to the outside through a through-hole 14 formed to another surface of the ceramic substrate 12 and a third recessed section 13c.

Accordingly, a solidified glass sealing medium 18 has no defective sink mark after the completion of heat treatment. The through-hole 14 functioning as a vent hole is closed by fitting and sealing a cover member 21 having a 1mm diameter and 0.5mm thickness and being made of ceramics into the third recessed section 13c; thus, complete hermetic seal is conducted.

CONSTITUTION: In the transfer device provided with a transfer roller (transfer member) 2 pressing a transfer material P on a photoreceptor drum (image carrier) 1 and constituted so that a bias is applied to the transfer roller 2, the transfer material P is introduced into a transfer part A as the pressing part, between the transfer roller 2 and the photoreceptor drum 1 and a transferable image formed and held on the surface of the photoreceptor drum 1 is transferred to the surface of the transfer material P, the volume resistance value of a part or the whole of a transfer material guiding member 4 which is installed in proximity to the transfer roller 2 on the entering side of the transfer material of the transfer part A is set 10<5> Ωcm-10<10> Ωcm.  By such a constitution, the actual resistance value from the contact of the transfer material P with the transfer material guiding member 4 to ground is made extremely high and a leakage current flowing into the guiding member 4 from the roller 2 through the transfer material A can be suppressed lower. Consequently, most of transfer current is held on the transfer material P.

Filed: 1990-03-26
Abstract: PURPOSE:To eliminate such a danger that a driver might drive his car in keeping a power takeoff unit operated intact by mistake as well as to obviate any accident due to operation of the PTO unit during travel by stopping the PTO unit automatically if the vehicle gets running, whereas the PTO unit operates. CONSTITUTION:When a power takeoff switch 6 is turned on, a AND circuit 8 outputs an operating signal to a solenoid drive circuit 5 via a switch 10. Then a solenoid 4 is turned to ON, a selector valve 3 is changed over, compressed air is fed to a PTO unit 1 from an air feeder 2, connecting this PTO unit to an automatic transmission, and power takeoff is performed. In addition, a car speed signal detected by a car speed sensor 7 is outputted to a comparator 12 after being converted into electric potential from engine speed by an FV converter. In consequence, when it is larger than the setting potential, namely, car speed is more than the specified car speed, positive potential is outputted to a discriminator 9. If so, this discriminator 9 turns the switch to ON and interrupts an operating signal out of the AND circuit 8.
