Title: Ultrasonic flaw detector
Inventor: MATSUMOTO JIYUUMEI
IPC: G01N29/11
Filed: 1981-03-03
Abstract: PURPOSE:To improve the reliability of flaw detection of weld zones by allowing a probe to follow up and trace the weld zone with high accuracy by making effective use of the parasitic echoes obtained from the shoulder parts of weld beads. CONSTITUTION:The ultrasonic signal from a high voltage pulse generator 2 controlled by a synchronizing signal generator 1 is made incident toward the weld zone 31 of a steel pipe 30 by means of an ultrasonic angle probe 3. Transmission pulses and echo pulses are inputted to a clocking circuit 5 via a sensitivity adjusting circuit 4, and the time intervals of the transmission pulses T and the parasitic echo pulses B reflected by the shoulder parts N of the beads are measured. The measured value thereof and the set value of a setting circuit 11 are compared in a comparator 8, and the probe 3 is controlled to trace the weld line by a controller 9 so that the difference thereof is made zero. On the other hand, in a signal processor 12, the pulses B are gated just before they are inputted whereby the passage of the parasitic echo pulses is blocked, and only the flaw echo pulses F from the weld zone 31 are recorded in a recorder 13.

Title: Gel composition
Inventor: KUMAGAI SHIGENORI
IPC: A61K8/00
Filed: 1978-03-17
Abstract: PURPOSE:To prepare a harmless and stable additive for cosmetics, having excellent gelling characteristics, by adding specific amounts of a montmorillonite clay mineral modified with an organic compound and a surfactant/water liquid crystal to an organic solvent. CONSTITUTION:The viscosity of an organic solvent such as a low-boiling hydrocarbon containing a thickner comprising a montmorillonite clay mineral modified with a polar organic compound, is remarkably increased without using a harmful polar organic compound such as acetone, etc., by adding 10-200% of a surfactant/ water liquid crystal to the solvent. The surfactant and the water may be added to  the solvent separately in a ratio to form a liquid crystal having a lamellar structure; however, when the organic solvent has adverse effect to the stability of the liquid crystal, the surfactant and water is mixed together to form a liquid crystal before added to the solvent.

Abstract: PURPOSE:To realize the supply of the working power source before enclosure of the DC circuit by flowing the current less than the non-operation level of the relay of the exchange when the polarity of the telephone circuit is inverted and thus securing the terminal call detecting action. CONSTITUTION:When the calling is given via the exchange for the data collection, the polarity of the telephone circuit is inverted to make switch circuit 13 conduct. Then the operating current is supplied to call signal detection circuit 15 from auxiliary power circuit 16. In this case, the consumption current is limited to the current less than the non-operation level of the relay which detects the loop current within the exchange, thus avoiding the action for the incoming detection at the exchange side. Then circuit 15 becomes active to detect the call signal transmitted from the exchange side. And then connection circuit 17 is started. Thus the telephone circuit is connected to the data terminal T via circuit 13 and 17 to secure the supply of the fixed current to the data terminal. In this case, for the consumption current, the current over the sensitivity level of the exchange relay is flowed in order to realize the incoming detection at the exchange side.

IPC: G11C29/00
Filed: 1989-02-10
Abstract: PURPOSE:To improve redundancy efficiency by providing a shared spare line substitutable a defective word line or bit line on an ordinary cell array selectively in a redundant cell array. CONSTITUTION:It is assumed that either the word lines WL in the ordinary cell array 3 is defective. The row address data RA and the inverse of RA of a defective cell are compared with row defective cell address data RRA and the inverse of RRA from a row defective cell address memory 7x at a row address comparator 8x. When both data coincide, the comparator 8x outputs a coincidence signal RRS. In the signal RRS, command information to perform redundancy and information to instruct which spare line of spare lines RWL0-7 in the redundant cell array 16 should be used are included. A row decoder 2 becomes inactive by the signal. The coincidence signal is inputted to a row selection circuit 14, and since no column selection signal CRS from the comparator 8x exists at that time, the circuit 14 outputs a signal representing a content corresponding to the coincidence signal to a redundant X decoder 15x, an address switching circuit 17, and an input/output buffer 15. The decoder 15x decodes the coincidence signal, and selects the spare line RWL0-7 in the array 16.
