Title: Dirt measuring instrument for detection electrode of liquid level gauge
Inventor: KUSUMI KYOHEI
IPC: G01F25/00
Filed: 1990-06-29
Abstract: PURPOSE:To easily conform the dirt of the detection electrode and to clean the detection electrode before the liquid level gauge malfunctions by measuring the resistance value of the detection electrode from the value of a current flowing to the detection electrode. CONSTITUTION:While the lower end of the detection electrode 12 is dipped in fed water, a detected voltage Vk and a reference voltage VS which are applied to a differential voltage amplifier 22 are nearly equal in value, so an excitation signal is outputted to neither the amplification part 22 nor a relay driving part 24, so that no driving signal is outputted from the driving part 24 to a feed water pump 6. If the water level in a water level detection tube 8 drops until the lower end of the detection electrode 12 is exposed above the water surface, the detection current (i) flowing through a detected resistance 19 decreases, so the detected voltage Vk applied to the amplification part 22 through a rectifying amplification part 20 and a buffer 21 also decreases. Therefore, the excitation signal is outputted from the amplification part 22 to the relay driving part 24 and the driving signal is outputted from the driving part 24 to the feed water pump 6, thereby feeding water to a boiler.

Title: Quality evaluating method for brazing
Inventor: SAITO SHIGERU
IPC: G01N25/72
Filed: 1986-07-23
Abstract: PURPOSE:To evaluate the quality of brazing immediately, i.e. in real time by measuring the thermoelectromotive force between materials to be welded and evaluating the quality with this thermoelectromotive or thermoelectromotive force and a heating time. CONSTITUTION:A probe 15 abuts elastically on a conductor 3 with the spring force of a spring 16 and another conductor 3 contacts a probe 17. A voltage detecting circuit 21 detects the thermoelectromotive force between conductors 2 and 3 which are detected by probes 15 and 17. When the thermoelectromotive force detected by a voltage detecting circuit 21 is not within a predetermined normal range, a stopping means 22 stops subsequent manufacturing processes and a display means 23 such as a buzzer and a red lamp indicates that the quantity of brazing is defective. When it is judges that the electromotive force detected by the voltage detecting circuit 21 is normal, a means 24 for working operation in the next process is activated.

Title: Method and device for flaw detection by fluid transmitted acoustic wave
Inventor: HONMA TAKESHI
IPC: G01N29/04
Filed: 1984-08-21
Abstract: PURPOSE:To perform flaw detection which does not requires any acoustic wave generating device and is effective to a metallic structure by receiving a fluid transmitted acoustic wave, generated when an air flow is produced in a material to be tested under a vacuum or with compressed air, by an acoustic wave receiver. CONSTITUTION:A can 4 which is made of transparent acrylic resin, etc., and has an elastic body 9 of rubber, etc., adhered to an opening end surface is brought into contact with the material 5 to be tested which is a structure made of nonmetal such as timber and concrete, and a vacuum pump 1 is put in operation to evacuate the can 4. If the material 1 to be tested has a defect like a cavity 14, an air flow is generated in the material 5 to be tested and an acoustic wave is therefore generated by the air flow. This acoustic wave is received by the acoustic wave receiver 6, whose output is amplified 7 and displayed on a cathod- ray tube, thus checking the defect state of the object material 5.

Title: Compression system for character code data
Inventor: KONDO ISAO
IPC: G06F17/21
Filed: 1989-07-05
Abstract: PURPOSE:To compress the character code data by using a KANJI (Chinese character) phrase code dictionary and applying a process system where the character codes and the phrase codes are unified into 2 bytes and 3 bytes respectively. CONSTITUTION:The character codes 9 are defined when the most significant bit of a 1st byte is equal to '0', and the KANJI phrase codes 10 are defined when the most significant bit is equal to '1' respectively. The codes 9 have 2 bytes and are assigned to 32K characters with remaining 15 bits, and the codes 10 are assigned to 32K characters of the codes 9 with remaining 15 bits of 1st and 2nd bytes and then assigned to the code of a KANJI phrase starting at the head character of a phrase at a 3rd byte. The character strings of the KANJI-KANA (Japanese syllabary) sentences are changed into the codes by a character code dictionary 3. A character string code part 8 of a KANJI phrase code dictionary 6 is retrieved by a deciding means 4. When the coincident codes are detected, the data on a code part 7 is read out. If no coincident code is confirmed, the character code read out of the dictionary 3 is stored in a storage means 5 as it is. Thus the character code data can be compressed and converted.
