IPC: H04N19/196
Filed: 1990-07-04
Abstract: PURPOSE:To display lots of reduced patterns in less arithmetic quantity and time by extracting only a DC component of a data and multiplying a prescribed value from a ROM coefficient with an extracted data and interpolating the data. CONSTITUTION:A data is divided into a quantization matrix and a picture data by a division circuit 2 and the picture data subjected to fixed length processing is subjected to inverse quantization by an inverse quantizing device 4 by using a DC component 20 of a quantization matrix in a sent data. Then the data of the DC component subjected to inverse quantization is inversely converted. An address data is converted by using a coefficient ROM 5 and the converted data is interpolated according to the reduction rate of the displayed pattern and a required magnification depending on a picture element number M of one side of a data block subjected to orthogonal conversion. Thus, since only the data DC component is decoded, lots of reduced patterns are displayed in less calculation quantity and time.

Title: Current sensor
Inventor: NOZOE TOSHIYUKI
IPC: H01L43/08
Filed: 1994-07-28
Abstract: PURPOSE:To provide a high sensitivity current sensor excellent in output linearity through the use of a servo system employing a magnetoresistive element. CONSTITUTION:A magnetoresistive element sensor 7 senses magnetic field induced by a current IL to be measured flowing through a line 3 and produces a differential voltage corresponding to the strength of magnetic field. The differential voltage is fed through an error detecting section 17 to a compensation current control section 18 which feeds a compensation current IS through a compensation current line 18' thus canceling the magnetic field induced by the current IL to be measured. The voltage drop across a load resistor 18 due to the compensation current is then amplified at an output converting section 20 thus producing an output voltage.

IPC: G11B5/53
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To facilitate exchange of a grounding device, that is, a around ring by bringing the contact part of the ground rung interposed between a collar fixed to a shaft and imparting preload to an internal ring of a bearing and a motor stator fixed to the collar into contact with the external ring of the bearing and electrically conducting the internal ring with the external ring.

Title: Vent duct
Inventor: NAGATA TAKUJI
IPC: B60H1/26
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To reduce the pressure loss at a blow-out hole, and to prevent the invasion of the water such as a can washing water. SOLUTION: Butterfly valves 18 surface-contacting to the outer end faces of an upper partition piece, a lower partition piece, a left partition piece, and a right partition piece, have the ends of the inclination α shown in a dashed line Z, in order to maintain the blocking condition of the air holes 30 by their self-weight, and as a result, the inner surfaces of the butterfly valves 18 are surface-contacted by the weights (vector components) of the butterfly valves 18. Since the blocking condition is maintained by only the self-weight of the butterfly valves 18, the blocking condition can be released easily by the air pressure difference more than the self-weight.  Even though the water pressure is applied from the outer side of the car room in the car washing condition, the blocking condition is maintained, and since the water adhered to the outer surfaces of the butterfly valves 18 can flow to the lower direction, the water in the car washing condition never flows into the car room.

Title: Solid-state image pick-up device
Inventor: UEHIRA KAZUO
IPC: H04N5/369
Filed: 1989-07-10
Abstract: PURPOSE:To improve the quality of image pick-up picture surface eliminating any dispersion caused when the saturated charge level is decided by the accumulated charge level of a photoelectric conversion element by a method wherein the accumulation charge level of a floating diffused layer in a charge detection part is set up fo be lower than that of the photoelectric conversion element. CONSTITUTION:A reset electrode 2 is impressed with a high level reset pulse to feed signal charge to a reset diffused layer 4 and after making a floating diffused layer 1 in an empty state, the reset electrode 2 is impressed with low level voltage. Since the impurity concentration in the n type region 3 beneath the reset electrode 2 is made higher to lower the potential in this region 3 so that any surplus signal charge transferred to the floating diffused layer 1 may flow into the reset diffused layer 4 through the region 3 beneath the reset electrode 2 even if the reset electrode 2 is impressed with the low level voltage. At this time, when the impurity concentration in the n type region 3 is specified at proper value so as to make the accumulable charge level of the floating diffused layer 1 lower than that of a photoelectric conversion element, the saturated signal charge level of the title solid image pick-up device can be decided by that of the floating diffused layer 1 thereby enabling a picture image subject to no dispersion near the saturation to be obtained.

Title: Blooming method for steel ingot
Inventor: SUZUKI KIYOSHI
IPC: B21B1/46
Filed: 1986-07-30
Abstract: PURPOSE:To prevent the un-press welding in the central part of a steel ingot and to prevent surface cracking by subjecting the steel ingot heated in a heating furnace or soaking pit to quick cooling by a refrigerant to decrease the temp. difference between the surface layer and the central part to a prescribed temp. or below, then blooming the ingot. CONSTITUTION:A bloom which is drawn from a cooled casting mold of a continuous casting device and is cut to an adequate length is immediately transferred to the heating furnace or soaking pit. The central part temp. TCO is in the state of the temp. higher than the surface layer temp. TSO at this time. The central temp. TC falls once and rises again during the time when the steel ingot is heated in the heating furnace, etc., until the surface layer temp. TS attains the prescribed temp. The steel ingot is ejected from the heating furnace and is immersed into a cooling water tank at the point of the time t1 when the temp. difference between the surface layer part and the central part is DELTAT1. The surface layer part is shrunk by such quick cooling. The pores, etc., interposed in the central part are press-welded when the blooming is started at the point of the time when the temp. difference DELTAT3 between the surface layer part and the central part decreases to the prescribed temp. difference or below. The density in the central part is thereby increased, by which the un-press welding is prevented and the high-strength slab is obtd.
