Title: Filter circuit and electronic parts
Inventor: OYAMA HIROHISA
IPC: H03H7/06
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a filter circuit, which eliminates a noise component from a passing signal and doesn't cause the noise component to flow even to the ground, and electronic parts where this filter circuit is formed. SOLUTION: A fundamental signal as the passage object and the other unnecessary noise (higher harmonies or the like) which are included in a signal inputted to an input terminal 11 are separated by a low pass filter and a high pass filter, and the fundamental signal is outputted from an output terminal 12 through the low pass filter. The unnecessary noise component like higher harmonics passes the high pass filter and is supplied to a resistor R and is consumed by the resistor R and is radiated as heat. Thus, the noise component is not returned to the signal source and doesn't flow to the ground (earth terminal 13) and is approximately completely absorbed by the resistor R, and then, a conventional adverse effect on electronic apparatus is suppressed.

Title: Communication controller and communication system using the same
Inventor: HOMITSU YOSHIAKI
IPC: G06F13/28
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To enable a small-scale circuit to easily deal with a system bus width larger than the bus width of a communication controller main body by controlling the DMA(direct memory access) transfer and also generating a signal to show that plural data are continuous. SOLUTION: The DMA transfer of plural data are performed between external devices such as a CPU 53, a memory 54, etc., via an external data bus 50. This DMA transfer is controlled by a DMAC control circuit 30 of a communication controller 1. The circuit 30 produces a signal to show that plural data are continuous. Therefore, the alignment of data is controlled by the circuit 30 and the fast transfer of data is attained. Furthermore, plural data can be turned into a single piece of data by such a simple alignment circuit 48 as a buffer circuit, etc.

Title: Method for controlling molten steel temperature in tundish
Inventor: KIMURA SEII
IPC: B22D46/00
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To execute stable casting without clogging caused by the solidification by deciding the last molten steel temp. in the preceding process so that the difference between the lowest temp. in the molten steel temp. change with time in a tundish and the solidified temp. of the molten steel becomes a specified value. SOLUTION: The molten steel temp. incorporated in a ladle after tapping the molten steel is made to an initial value and the molten steel temp. change with time in the ladle based on a prescribed calculating formula and further, the molten steel change with time by using this temp. in the ladle are obtd. Then, the last molten steel temp. in the preceding process as the initial value is decided so that the casting temp. becoming the min. value becomes higher by a specified temp. than the solidified temp. of the molten steel. The specified temp. at this time, i.e., the temp. difference (overheat degree) between the lowest casting temp. and the solidified temp. is desirable to set to >=8 deg.C from a viewpoint of the prevention of the solidified clogging.  By this method, since the molten steel temp. at the preceding process to the casting is unnecessary to be too high, the energy in this process can be saved.

Title: Peak holding circuit
Inventor: OGAWA YUUJI
IPC: G01R19/04
Filed: 1984-04-03
Abstract: PURPOSE:To avoid the reduction of voltage due to the discharge of a capacitor even in case the transmission time is increased in a semidouble transmission mode, by applying a peak holding inhibition signal directly to the 2nd input terminal of a differential amplifier serving as a comparator. CONSTITUTION:NPN type transistors TR20 and 21 constituting a differential amplifier are connected in common with each other through both emitters and grounded via a constant current circuit 22. A signal B to be peak-held is applied to the base of the TR20, and a signal C is delivered to a comparator from the base of the TR21. This peak holding circuit attains a peak holding function when a signal A is set at a low level. When the signal A is set at a high level, i.e., a peak holding inhibition signal is supplied, the base of the TR21 is forcibly set at a high level with a TR27 biased adversely. Thus the discharge of a capacitor 29 is stopped with the TR20 and TR21 turned on and off respectively. A TR30 is also turned off. In this case, a diode 25 functions to avoid a case where the TR21 is saturated and the signal A turns on the TR30 via a B-E junction of TR21.

Abstract: PURPOSE: The titled health drug, prepared by using anhydrous water glass powder, corresponding to JIS Nos. 2, 3 and 4, and having a slight solubility in water with a feed or remedy, and capable of promoting the appetite and the remedy and increasing the activity of a fish.  
     CONSTITUTION: Anhydrous water glass powder (crystal water glass powder), corresponding to JIS Nos. 2, 3 and 4, and having a slight solubility in water is used with a feed or remedy, e.g. methylene blue, to give a health drug for fish farming capable of promoting the appetite and remedy and increasing the activity of a fish. The pH is adjusted by sodium carbonate, acid sodium phosphate, etc. in the health drug for fish farming. However, the anhydrous water glass powder has a low solubility as opposed to the powdered water glass, and about (4W15)/1 that of the sodium carbonate. After the introduction into a water tank, the drug is dissolved therein slowly without clouding the interior of the tank with time. The pH is changed slowly to activate the fish and promote the appetite thereof.

Abstract: PURPOSE:To reduce oscillations by forming a rotary shaft and a polygon mirror of light materials having the same thermal expansion ratios, and thereby preventing dislocation of the polygon mirror at the time of high speed rotation. CONSTITUTION:A mirror receiving flange 2, a mirror portion of a rotary shaft 21, while the polygon mirror 25 is fitted to an upper outer peripheral surface 21b of the rotary shaft 21.
