Title: Damage detector of heat insulator material in liquefied gas tank
Inventor: UEDA KIMITOMO
IPC: F17C13/12
Filed: 1981-02-09
Abstract: PURPOSE:To detect damage and its position of a heat insulating material, by arranging air-tight pipes in the inside of a tank construction material and sealing gas, liquefied or solidified at a certain degree of low temperature, in said air-tight pipe. CONSTITUTION:An inner shell 3 is locally cooled by liquefied gas, and air-tight pipes 6 in the vicinity of the inner shell are cooled. The cooled air-tight pipe 6 cools gas in its inside to liquefy or solidify the gas, when liquefied, the liquid soaks into a fiber 8 cooled to low temperature in the pipe 6, finally the liquied or solid is accumulated in a low temperature part, in a short time the gas in said pipe 6 is all liquefied or solidified to widely decrease pressure in the pipe 6. Accordingly, if the inner shell 3 is cooled to temperature not higher than a preset level, the cooled pipe 6 causes the decrease of pressure in the inside and is detected.

IPC: G11C17/00
Filed: 1987-01-30
Abstract: PURPOSE:To prevent the deterioration of elements by providing a 2nd area writing the number of times of rewrite in addition to a 1st area, writing data to the 1st area only when number of times of the rewrite is less than a prescribed value and rewriting the numeral in the 2nd area to a value incremented by +1. CONSTITUTION:A CPU 1 applies data rewrite management to an E<2>PROM 5 and applies various processings, and the E<2>PROM 5 is provided with a storage area 51 writing a conventioanl data and the rewrite number of times storage area 52 storing the number of times of rewrites of the data written in the storage area 51. A comparison means, prior to write a data in the memory 5, reads the number of rewrite times written in the 2nd area 52 of the memory 5, compares it with prescribed value and a write means writes the data into the 1st area 51 only when the number of times of rewrite is less than a prescribed value. Since the rewrite number of time write means rewrites the numeral of the 2nd area into a numeral incremented by +1 when the write to the 1st area 51 of the data is finished, only the rewrite up to the maximum number of times -1 is applied to the memory 5. Thus, the element is not deteriorated.

Title: Attached processor and telecommunication system containing it as well as method for transfer of call in remote system
Inventor: ROBAATO DEIIN RIIDAA
IPC: H04M3/38
Filed: 1995-01-11
Abstract: PURPOSE: To prevent the fraud of a telephone charge by means of a caller using an attached processor in a remote communication system having a call transfer function. CONSTITUTION: This attached processor 16 sends an address to which a call such as an extension number is to be transferred and address termination display such as pound sign to exchange systems 12 and 14. Address termination display which is sent prevents the exchange systems 12 and 14 from receiving further address information from the caller 10. The caller 10 corrects the sent address and the call is prevented from being transferred to the address different from the sent address such as a long distance telephone number. Thus, the fraud of the telephone charge using the attached processor can be prevented.

Title: Continuous annealing of titanium and titanium alloy strip
Inventor: NISHIKAWA TOMIO
IPC: C23C8/28
Filed: 1980-02-18
Abstract: PURPOSE: To form hardened layer of a desired hardness on the surface of a titanium or titanium alloy strip without causing oxidative coloration on the surface by annealing the strip in an ambient gas containing N or Ar gas containing a small amount of O 2 .  
     CONSTITUTION: A cold-rolled titanium or titanium alloy strip is coiled up and then subjected to a continuous annealing treatment at 650W750°C in Ar gas containing 30W100ppm of O 2  or N 2  or a mixture of Ar and N 2  as an annealing ambient gas. Since the heating temperature is comparatively low, no oxide or nitride of Ti is formed on the surface of the strip and therefore, no coloration involved occurs on the surface. Also, since O 2 , N 2 , or both in the ambient gas are solidity dissolved on the surface of the strip, a hardened layer of a high hardness is formed on the surface of the strip, thereby preventing the surface of the strip from being flowed.

Filed: 1987-01-28
Abstract: PURPOSE:To supply a stable pattern by showing 0 and 1 in the N-bit codes so that the program mistakes, troubles, etc. of a ROM can be simply detected. CONSTITUTION:A K-bit counter 1 delivers the count value (a) to terminals A1-AK respectively. Both 1 and 0 patterns are programmed into a pattern generating ROM 2 so that 1 and 0 are produced in the form of a 1 pattern of 4 bits and a 0 pattern of 4 bits respectively. Then the ROM 2 supplies the count value of the counter 1 in the form of addresses through the terminals A1-AK and delivers successively M pieces of output to the terminals B1-BM based on said addresses. A pattern detecting circuit 3 supplies the inputs received from the terminals B1-BM to the pattern detecting parts 31-3M respectively and outputs '1' and '0' with detection of the 1 and 0 patterns respectively. While error pulses are outputted when other patterns are detected. In such a case, the ROM 2 includes an error pattern when the output value (a) of the counter 1 is equal to 8-11 and an error pulse is outputted to the output (d) of an output terminal D1 of a detecting part 31.

Abstract: PURPOSE: To make a seal impression impossible to read even by using infrared or ultraviolet rays and prevent forgery of a seal by employing ink made by adding a fluorescent material to one component of a two-part color former for printing, then stamping a seal by using ink containing the other component and coating the seal impression with an ultraviolet absorptive film.  
     CONSTITUTION: The portion of a certificate 1 of securities made of paper, film or the like to be sealed is printed 2 by using ink containing the A material in a two- part (A and B having the opposite type to each other) heat-sensitive color former and a fluorescent material. Then, a seal is stamped to the printed portion 2 to make a seal impression 3 by using ink containing the B material in said color former instead of a vermilion seal ink. Under said condition, ultraviolet whose visible region has been out is applied thereto to confirm the seal impression 3 by the luminance difference between the reflected rays from the seal impression 3 portion and its periphery. Then, a cover 4 of transparent film containing an ultraviolet absorptive agent is attached thereto through an adhesive 5. Thereby, the seal impression 3 cannot be read even by applying ultraviolet rays. However, reacting the A and B materials on heating causes them to form a color which can be read.
