Abstract: PURPOSE:To detect a leakage point easily and accurately by covering an object to be inspected with a transparent cylindrical body, injecting a foaming agent into the space formed around the object to be inspected, and evacuating the space by a vacuum pump. CONSTITUTION:The cylindrical body 1 which has opening on both ends and is made of transparent material is opened by unlocking hooks 2 and covers a tubular body to be detected so that an inspection objective point is covered, and the hooks 2 are locked. Then, the bottom part of a foaming agent container 9 is elevated to force the foaming agent 12 in the container 9 into the space part 13 between the external wall of the tubular body 11 to be inspected and the internal wall of the cylindrical body 1, so that the external surface of the body 11 is impregnated with the foaming agent. Then, the vacuum pump 9 is put in operation and a valve 7 is opened to evacuate the space part 13 because the inside is held airtight by packing materials 3 provided to the internal surfaces of both end parts of the cylindrical body 1. If the body 14 has a defective part 14, foaming 15 by the foaming agent 15 occurs to the external surface of the body 11 and is observed through the transparent cylindrical body 1, so that the leakage point is detected easily.

Inventor: MATSUMOTO YASUKI
IPC: G11B7/24035
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily detect a boundary region at a high speed by disposing the boundary region consisting of rugged pit patterns not appearing in the information pit patterns of a mirror or ROM region between groove tracks of a recessed shape or projecting shape and pit tracks where information is recorded in the form of rugged pits. SOLUTION: The optical disk is divided into a RAM region 102 and the ROM region 103 and a boundary region 104 consisting of a mirror part is set at the boundary between the RAM region 102 and the ROM region 103. Since the points where the pits are not formed at all over such several tracks do not exist on the optical disk, the easy detection of the boundary region 104 at a high speed is possible. If the changeover of a tracking error signal is executed by detecting whether the recording enters the RAM regions 102 or the ROM region 103 in this boundary region 104, the tracking control in the ROM region 103 can be executed with high accuracy.

Abstract: PURPOSE:To enable to prevent rail-displacement due to relative advance of an unit to that of a rail by connecting a pressure fluid source to a cylinder and contracting a releasing arm when access of a processing unit to a movable rail is detected and releasing it for non-detection period. CONSTITUTION:When processing unit moves forward, a detector 19 once becomes inoperative in an intermediate position to discharge pressure fluid, and then operates at the advanced position to introduce pressure fluid. A movable rail 6 is again pressed by spring 12 and pressure fluid and retrained unmovable at the position together with the gang head 9, the head 9 moves forward in coupled condition by the subsequent advance of the processing unit and performs specified operations. Next, when the processing unit retracts together with the head 9, the detector 19 once becomes inoperative by the subsequent retraction of the processing unit, so that pressure fluid in a cylinder 13 is discharged, an expanding/contracting arm 15 can expand easily because only its spring 12, acts on the contraction side. Thus, the expanding/contracting arm connecting the unit to the movable rail can favorably tie together these components.

Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a small sized received call informing device with light weight at a low cost and with small power consumption without causing electromagnetic noise or spark noise. SOLUTION: The device is made up of an elastic strip 1 whose one end 11 is fixed to a case 4 of a portable telephone set, a weight 3 fitted to the other end 12 of the elastic strip 1, and a piezoelectric ceramic vibrator 2 adhered to the elastic strip 1. When an AC voltage with a low frequency is applied to the piezoelectric ceramic vibrator 2, the piezoelectric ceramic vibrator 2 is in bent vibration and since the weight 3 is vibrated with a large amplitude, the telephone set itself is vibrated to deliver the arrival of a call to a human body. Furthermore, in the case of applying an AC voltage with a high frequency to the piezoelectric ceramic vibrator 2, the case 4 of the telephone set acts like a sounder and is vibrated to output a sound thereby informing the arrival of the call.
