Title: Rotary head type digital audio signal reproducing device
Inventor: YASUSATO YOICHIRO
IPC: G11B20/18
Filed: 1989-11-22
Abstract: PURPOSE:To prevent a noise tone from being generated in a discontinuous part by providing a means to mute the discontinuous part between the adjacent blocks of digital audio signals to which error correction is executed. CONSTITUTION:When an error correcting circuit 10 sets the mute flags of respective sectors in the digital audio signals to '1' respectively, an audio I/O circuit 11 detects '1' of the mute flag and supplies a control signal to a mute signal generator 13. With this signal supply, a multiplexer 14 multiplies a mute signal, which is supplied from the mute signal generator 13, with the digital audio signal from the audio I/O circuit 12. Thus, since the mute means composed of the audio I/O circuit 11, computer 12, mute signal generator 13 and multiplexer 14 mutes the discontinuous part between the adjacent blocks of the digital audio signals to which error correction is executed, the noise tone can be prevented from being generated in the discontinuous part.

Title: Method for removing nonmetallic inclusion of molten metal
Inventor: OKAZAWA KENSUKE
IPC: B01J20/28
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To improve the removal efficiency of nonmetallic inclusions without closing a nozzle by suspending particles on which nonmetallic inclusions are easy to stick in molten metal flows in a nozzle for molten metal injection into a tundish or mold. SOLUTION: This removing method is a system which sticks nonmetallic inclusions 3 on particles 5 suspended in molten metal 2 and not a method which supplements gaps of a porous body with nonmetallic inclusions like before, so the molten metal 2 is never impeded from passing owing to the blocking of the gaps with the nonmetallic inclusions 3. Further, the flow rate of the molten metal in the nozzle 4 for molten metal injection into the tundish or mold is high and its flow pattern is complicatedly disordered, so the probability of collisions between the particles 5 and nonmetallic inclusions is high and the removal effect on the nonmetallic inclusions is large. The particles 5 are formed of a material which neither reacts on the molten metal nor melts at the molten metal temperature and in concrete, ceramic-made balls formed by burning a raw material such as alumina into spheres are used.

Title: Radiation type air conditioner using electronic freezing element
Inventor: OGURA TADASHI
IPC: F24F1/00
Filed: 1990-11-09
Abstract: PURPOSE:To obviate the installation of a waste emission means exclusively designed by exhausting indoor air outdoors by natural convection by way of an exhausting passage formed on a rear side of a radiation panel. CONSTITUTION:During heating time, natural convection occurs in a waste passage by cooling on the rear side where the natural convection flows downward along a wall surface 12. The indoor air falling down along the wall surface 12 is introduced into an exhausting passage 13 on the rear side 1b of a radiation panel 1 from an opening section on a ceiling side 11 where the air is consecutively exhausted outdoors from an exhaust port 16 on the lower side opened on the lower part past the exhausting passage 13. Since the lower part of the exhausting passage 13 is kept open during cooling time in contrast with heating time, the indoor air which rises by natural convection along the wall section 12 flows to the upper part 1c on the rear side of the radiation panel 1 from the lower part 1d.
