Title: Ultrasonic flaw detector
Inventor: KAWAGUCHI KANAME
IPC: G01N29/26
Filed: 1982-10-22
Abstract: PURPOSE:To perform efficiently a scan on a sample to be inspected by arraying plural ultrasonic wave probes in the main scanning direction of an ultrasonic wave probe means. CONSTITUTION:A container 13 filled with an ultrasonic wave medium 14 is provided to a probe base 2 which moves the sample 15 to be inspected in a main and a subscanning direction. The lower part of the container 13 is opened and the medium 14 contacts the surface of the sample. Many ultrasonic flaw detecting elements 16 arrayed linearly or zigzag are set in the medium 14 to obtain information on the thickness of the sample by transmitting and receiving ultrasonic waves. The array direction of the ultrasonic flaw detecting elements 16 coincides with the main scanning direction of the probe base 2 and the scanning width is as wide as the array width of the ultrasonic probes, so the movement pitch in the main scanning direction is increased.

Title: Magnetic recording medium
Inventor: SAKAI KEITARO
IPC: G11B5/73
Filed: 1985-08-26
Abstract: PURPOSE:To improve the over-write characteristic of a magnetic recording medium by using barium ferrite magnetic powder having <=-45dB erasing value measured by an AC powder erasing method for a magnetic recording layer. CONSTITUTION:With regard to the over-write characteristic, 12KFRPI rectangular wave is written on a medium and 48KFRPI is written in superposition thereon. An output difference is then measured. The over-write characteristic is better with the higher output difference. The over-write characteristic is 26dB when the erasing value is <=-45dB and said characteristics is 30dB wen the erasing value is <=-50dB, thus the over-write characteristic of the magnetic recording medium improves. The recorded waveform is not erased and appears as an error when the value exceeds -45dB. The over-write characteristic of the medium is thus improved by maintaining the powder erasing value of the magnetic powder at a certain specified level, by which the poor characteristics of the barium ferrite itself is eliminated.

Title: Near infrared humidity measuring instrument
Inventor: NAGASE MAMORU
IPC: G01N21/3554
Filed: 1990-07-13
Abstract: PURPOSE:To accurately measure the humidity of the inside of piping even when a light-emitting or light-receiving device and a reflecting plate are stained by reflecting the radiated near infrared radiation at a light receiving device when the light receiving device is in its positions near and away from a light emitting device, and calculating the humidity from the amount of the near infrared radiation reflected. CONSTITUTION:Near infrared rays of such wavelength as to be absorbed into water are converted to light generated from a light-emitting element 7 serving as a light-emitting device and are introduced into a two-beam optical fiber 9 via a filter lens 8 which allows transmission of only the light of that wavelength therethrough and are applied to piping 1 from the light-emitting surface of a two-beam optical fiber connector 2. The near infrared rays applied are reflected when the reflecting plate 6 of a vane 5 rotated by gas flow within the piping 1 faces the rays while in its positions near and away from the two-beam optical fiber connector 2, and are alternately transmitted through the two-beam optical fiber 9 from the light receiving face of the two-beam light fiber connector 2 and received by a light receiving element 10 serving as a light receiving device and then an electric signal proportional to the amount of the light received is generated. The electric signal is input to a calculating device 12 via an amplifier 11. The calculating device 12 calculates the moisture of the inside of the piping 1 from the difference between levels of reflected light alternately input thereto.

Filed: 1990-07-13
Abstract: PURPOSE:To provide a high effect of suppressing sound, eliminate any bad influence for a combustion part even if an inverse air flow is applied from an outer area and further enable an easy assembly of a muffler structure by a method wherein an exhaust gas collecting box is fixed to a lower part of a main body of an exhausting case and a U-turn shaped exhausting gas passage is fixed to its inner side. CONSTITUTION:Ignited exhaust gas passes through a heat exchanger and enters an exhaust gas collecting box 2 at a lower part of a main body 1 of an exhaust gas case. The gas becomes an ascending stream. Sound of the gas is absorbed by absorbing agent A6 through a plurality of U-turn shapes of guide plate A3 and guide plate B5 and through punched small holes in the guide plate A3 and the guide plate B5 spaced apart by a certain specified distance. In particular, there is a more sound absorbing effect at a striking part of the U-turned shape. Even at a side part, the sound is absorbed by the sound absorbing agent B8 at a part striking against the exhaust gas passage and a slow zig-zag flow is generated and sound is absorbed, thereafter the gas is discharged out of a discharging port louver 9 in front of the main body 1 of the exhausting case. This construction becomes a resistor even in the case that an inverse air is applied from an outer side of the main body and then there is no bad influence for the combustion part.

Abstract: PURPOSE:To improve an efficiency of a removal operation by inserting a remover of stuck dust into an off-gas piping and by contacting an outer circumferential surface of the remover to an inner surface of the off-gas piping to remove the dust stuck on the surface. CONSTITUTION:A sluice valve 7 for keeping gas tightness is provided at an upper wall of a glass melter furnace 1 to shut off an interconnection with an off-gas piping 2.
