Title: Recorder
Inventor: SAKAI MASAHIKO
IPC: H04N1/411
Filed: 1991-03-12
Abstract: PURPOSE:To obtain a recorder improved in recording quality of lightface characters and lines. CONSTITUTION:When bit map information is compressed by a compression circuit 6 to be stored in a bit map memory 5, the bit map information is corrected in accordance with the compressing ratio of the compression circuit 6 before compressed by the compression circuit 6. The bit map information corrected and compressed in this manner is stored in the bit map memory 5. This information is read and expanded by an expansion circuit 7, and it is recorded. In this manner, for example, by correcting lightface character or line data to boldface data, the blur or missing of a line can be prevented, and a deterioration in recording quality can be prevented.

Filed: 1988-02-29
Abstract: PURPOSE:To remove the unstability with a video clock at the head of a video signal, by providing a synchronous signal forming circuit for forming a raster synchronous signal from a video clock and a video clock forming circuit for making the cycle of the video clock long only during the raster synchronous signal. CONSTITUTION:A synchronous signal forming circuit 3 for forming a raster synchronous signal BD from a video clock and a video clock forming circuit 4 for making the cycle of the video clock VCL long only during the raster synchronous signal BD are provided and the video clock of the video clock forming circuit 4 is sent out to a controller 2. During a time when the controller 2 prepares for the head of a raster on the basis of the raster synchronous signal BD, the video clock VCL is stopped to prevent that data becomes unstable by delay and the video clock VCL is sent after output data becomes stable. By this method, the synchronism with the video clock VCL at the head of a video signal VDO becomes certain and the controller 2 may not prepare for data at a high speed.

Title: Absolute value arithmetic circuit
Inventor: KAWAMURA SHIGENORI
IPC: G01R19/04
Filed: 1978-04-21
Abstract: PURPOSE:To obtain the approximate value of the vectorial absolute sum of two signals by giving an arithmetic process to each absolute value of the two signals through a simple circuit constitution. CONSTITUTION:When the optional coordinates is set to P (x, y) on the circumference of radius (r) and on the X and Y coordinates surface, the equaton of r = (x<2> + y<2>)<1/2> is satisfied. At the same time, angle POX = theta is set. Now, the absolute value of x and y are set to -x and -y respectively, and then RS is obtained under the condition of -x + (-y)/2<1/2> = r (costheta + sintheta)/2<1/2>. And the larger value between -x and -y is set to MaX (-x, -y) to satisfy MaX (-x, -y) = RM. Then if RS1 is used as th approximate value of (r) under RS + RM/2cospi/8 = RS1, the error can be minimized. RM1 features the error of 0.08r, that is, the operation becomes possible for (x<2> + y<2>)1/2 with the error of + or -4% with the positive and negative allotment. The error can be reduced furthermore if the number of steps is increased for the circuit.

Title: Detecting device of overload of power converter
Inventor: ISHIGURO MASAHARU
IPC: H02P29/40
Filed: 1991-03-12
Abstract: PURPOSE:To detect only a state of genuine overload reliably without estimating it as the overload that a detected value of an output current is large a little. CONSTITUTION:An output of a clamping circuit 5 becomes 0 when a deviation obtained at a deviation detecting point 1 is within a range of zero to DELTAIo, and it outputs the deviation as it is, in other cases. Since an output signal of the clamping circuit 5 holds zero when the deviation Sd is within the range of zero to DELTAIo, an output signal Si of an integrator 2 does not rise and an overload detection signal OL is not outputted.

Filed: 1993-02-12
Abstract: PURPOSE:To obtain a dehydration material which is capable of dehydrating to any specified moisture content without causing a component change, allows a dehydrated product to be handled easily as a recyclable CaO source by constituting a dehydration material of the specific weight % of coal cinder and at least, one type of the remainder such as quick lime, steel dust or slag. CONSTITUTION:A dehydration material is composed of 100wt.% or at least, 50wt.% of coal cinder and the remainder of at least, one type of quick line, steel dust or slag. Next, sludge 2 containing oil in a sludge tank 1 is transported to a kneader 4 using a screw conveyor 3, where the sludge 2 is kneaded with the dehydration material and the mixture is dehydrated. Consequently, the dehydrated material becomes powder, and the powder is carried to a storage site 6 using a belt conveyor 5. The coal cinder as a main component of the dehydration material reacts with water chemically to generate heat which, in turn, helps dehydration. In addition, the sludge is heated during the dehydration process to remove oil from the sludge. However, the dehydrated sludge contains a high percentage of CaO component.
