Abstract: PURPOSE:To make it possible to detect cracks and the like in the inside of a solid and the like quickly and accurately by providing a constitution which is provided with a striking device, a sound wave detector, a trigger circuit, first and second delay circuits, a peak detector, and a comparator. CONSTITUTION:A striking device 2 strikes a body under test 1 comprising a hard and brittle solid so as to cause vibration. Thus sound waves are generated. A sound wave detector 6 collects and amplifies the generated sound waves and outputs the sound wave signal. A trigger circuit 7 outputs a trigger signal when the sound wave signal has a sound pressure at a specified level or more. A first delay circuit 8 is operated by the trigger signal. The circuit 8 sets the starting time for receiving the output signal of the sound wave detector 6 and the receiving time period of said signal. A peak detector 9 is operated by the output signal of the delay circuit 8 and detects the peak value outputted from the sound wave detector 6. A second delay circuit 10 sets the reception terminating time of the output signal from the peak detector 9. A comparator 11 is operated by the output signal from the delay circuit 10, compares the peak value outputted from the peak detector 9 with a preset threshold value and outputs the compared value.

Title: Pickling treatment liquid
Inventor: KAJIWARA SHOICHIRO
IPC: C23G5/036
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To stabilize hydrogen peroxide without degrading a pickling capability by specifying the components of a pickling treatment liquid. SOLUTION: This pickling treatment liquid has a basic bath compsn. of a hydrofluoric acid-sulfuric acid-hydrogen peroxide system. The compsn. contains phenyl urea as a fourth component and satd. aliphat. alcohol as a fifth component. The initial amt. of addition of the phenyl urea and the holding concn. thereof are preferably 0.005 to 0.1wt.%. The satd. aliphat. alcohol itself hardly contributes to the stabilization of the hydrogen peroxide but the good stabilization of the hydrogen peroxide is attained with the smaller amt. of the phenyl urea to be used by using this alcohol in combination with the phenyl urea. As a result, the pickling capability is maintained high even if the concn. of the metals accumulating in the pickling bath increases and, therefore, the execution of the continuous treatment is effective.

Filed: 1995-02-13
Abstract: PURPOSE: To control tension as well as to prevent excessive tension by providing band brakes on both supply and take-up reels respectively and setting them to be a bite side when feeding and to be a relief side when taking up respectively. CONSTITUTION: When being an FWD mode, a tape coming out of the supply reel 1 is traveled via a guide post 29, a tension guide 27 and a tape guide 22a. Tension of a spring 36 is received by the brake band 38 at its moving end 38a via a tension arm 25, so that braking force is applied to a brake drum 40 of the supply reel 1, and the tension is imparted to the tape. When the tension is increased, the tension guide 27 is operated to weaken the braking force of the brake band 38 against the tension of the spring 36, and the tension of the tape is controlled to be constant. The fixing end 38b of the brake band 38 is so arranged that the brake should be on the biting side when feeding rotation, and hence on the relief side when taking up rotation to weaken the braking force.
