Inventor: MIYAHARA HIROAKI
IPC: B22D1/00
Filed: 1988-06-14
Abstract: PURPOSE:To make measurement of solid phase fraction easily and directly by blowing gas through a nozzle on the surface of semi-molten metal under solid-liquid coexisting condition and detecting injecting resistance of the gas received from the surface of the semi-molten metal. CONSTITUTION:The semi-molten metal 2 under solid-liquid coexisting condition is contained in a refractory-made crucible 1, and an injection nozzle 3 is arranged at near surface thereof. A compressed air supply source and a pressure detector 5 are connected with the injection nozzle 3, and an orifice 6 is set between the air supply source 4 and the detector 5. At the time of blowing air under the contact pressure on the surface of the semi-molten metal 2 from the nozzle 3, the metal surface is recessed in accordance with the solid phase fraction and the gas receives the injecting resistance. This resistance is detected as back pressure with the detector 5, and the solid phase fraction is obtd. from the solid phase fraction-back pressure curve beforehand obtd. from experiments. As the sampling is not necessary, the measurement of the solid phase fraction can be facilitated and is made direct.

Abstract: PURPOSE:To enable highly accurate measurement of current and a shape of a wall current monitor regardless of variations in length of a beam by using a magnetic core made of a magnetic material having a magnetic characteristic respectively up to a high-frequency range and a low-frequency range as such for the wall current monitor. CONSTITUTION:A shield case 7 houses a magnetic core 81 which comprises a material having a function as magnetic material with a high magnetic permeability in a high frequency range and a magnetic core 82 which comprises that having a function as magnetic material with a high magnetic permeability in a low frequency range. Hence, when a short beam passes through a beam duct 1, the lowering of a differentiation time constant can be presented by the action of an inductance of the magnetic core 81 having a function as magnetic material to a high frequency range. Hence, an output voltage of a monitor is obtained as proportional to the size of a wall current. As for a long beam, an attenuation of the output voltage of the monitor can be minimized as the differentiation time constant is longer by the action of an inductance of the magnetic core 82 with a high magnetic permeability in a low frequency area.

Title: Brake disc
Inventor: MAEDA NORIYUKI
IPC: F16D65/12
Filed: 1987-06-12
Abstract: PURPOSE:To reduce the weight of a disc and to improve the heat radiating performance by forming a groove or a row of holes on a brake face and positioning the inner end row thereof at the radially outside with respect to the fixing hole. CONSTITUTION:Odd number of slit grooves 5 are arranged with equi-pitch in both brake faces 4 of a disc 1 while inclining forwardly by an angle alpha in the rotary direction while the inner end section 5a of the slit groove 5 is arranged at the radially outside with respect to a bolt insertion hole 2 so as to arrange the slit groove 5 as close as possible to the bolt insertion hole 2 as a whole. A frictional force F functions under braking onto a portion of the disc 1 where the slit groove 5 is formed, but since the inner end section 5a of the slit groove 5 is positioned at the radial outside of the disc 1 with respect to the bolt insertion hole 2, the distance L between the frictional force F and the bolt insertion hole 2 is shortened thus reducing the moment Fl. Consequently, the disc 1 can take a high reduction rate of rigidity due to the slit groove 5 and a high strength.

Title: Moving vector detector
Inventor: UOMORI KENYA
IPC: H04N19/513
Filed: 1989-06-09
Abstract: PURPOSE:To reduce the detection error of a moving vector of the entire screen by calculating the degree of divergence of a moving vector of each area on the screen and invalidating the moving vector of an area where a difference from the moving vector of the entire past screen is large when the degree of divergence is large. CONSTITUTION:A moving vector detection section 11 detects a moving vector between fields or frames of an input picture signal by areas of screen and a moving vector discrimination section 13 judges whether or not a moving vector of the area is reliable. Then a moving vector of an area where moving vector decision information is valid is used, a divergence calculation section 15 calculates the degree of divergence of the moving vector. A divergence decision section 16 compares an input level with a prescribed threshold level and sets a divergence condition flag into the state of the presence of divergence when the degree of divergence DIV1 exceeds the threshold level. A vector invalid decision section 18 outputs invalid information invalidating the moving vector when the output of the divergence decision section 16 represents the presence of divergence and a difference with a lag component of the moving vector of the entire pattern is not within a prescribed error range.
