Title: Device for controlling quantizer of hybrid coder
Inventor: PEETAA BUOGERU
IPC: H04N19/60
Filed: 1992-06-04
Abstract: PURPOSE: To further reduce a transmission bit rate without the loss of picture quality by changing finely or coarsely the quantity of quantization under the control of coding control means when a data block is related with the background of scene. CONSTITUTION: A preprocessing unit 1 compares two continuous data in the sequence of data blocks. When these data are equal as a result of comparison and another system parameter is higher than a scheduled threshold value, a circuit b1 and a coding control means 3 regard these data as the 'background' and operate a quantizer 404 so as to set these 'representative' block data to fine quantization and as long as the 'background' data are not changed, the other block data are set to coarse quantization. When the compared result shows non-coincidence, on the other hand, the preprocessing unit 1 sets a background index to an initial value. As a result, the image including 'background' is processed at the low transmission bit rate but the picture quality is not lowered.

Inventor: OKUMURA TAKUO
IPC: C22C37/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a sand mold cast eutectic graphite cast iron difficult to generate a chill in the matrix structure by in corporating C, Si, Mn, P, S and Ti of prescribed compositions, and the balance Fe with inevitable impurities. SOLUTION: The cast iron has a composition consisting of, by weight, 3.3-3.7% CE value (=C+1/3Si), 1.5-1.8 the ratio (Si/C) of Si to C, 0.2-1.0% Mn, <=0.1% P, 0.006-0.05% S, 0.06-0.10% Ti, and the balance Fe with inevitable impurities. When the CE value is below the lower limit, chills are generated, and the cuttability is degraded. When the CE value exceeds the upper limit, flake graphite is crystallized. When the ratio Si/C is below the lower limit, flake graphite is crystallized, and when the Si/C ratio exceeds the upper limit, the chilling is generated. When the quantity of S is smaller than the lower limit, chills are easy to generate, and when it is larger than the upper limit, the eutectic graphite is difficult to crystallize. Similarly, when the quantity of Mn, P, and Ti, is outside the appropriate range, chills are generated, and flake graphite is crystallized.

Abstract: PURPOSE:To simplify a transportation or a practical installing work for a central hot water feeding device by a method wherein a plurality of instant hot water boilers are arranged in parallel to each other in such a way as a flowing water flowing from a water input side to a hot water output side is detected to perform an operation and further each of hot water output sides is connected to a hot water feeding going-pipe and a cold water input side is connected to a hot water feeding returning-back pipe, respectively, and the hot water boiling passage is provided with a remote operating valve. CONSTITUTION:A central control means 8 sends an instruction of opening or closing a remote operating valve 18 to an individual control means 6. Then, the returned hot water in a hot water feeding returning-back pipe 12 is mixed with the upper water of the cold water supplying pipe 14, flows at an upstream side of the hot water feeding returning-back pipe 12. In the instant hot water boiler 1 having an opened remote operating valve 18, the hot water is branched from the hot water feeding returning-back pipe 12, the hot water flows from a cold water input side (i) into a hot water boiling passage 7. When the hot water is heated while passing through a heat exchanger 2, the hot water reaches a hot water output side (o) and then the hot water is merged in the hot water feeding returning-back pipe 11. As the hot water feeding load is increased and a temperature of hot water flowing in the hot water feeding going-pipe 11 is decreased, a reduced hot water temperature is detected by a hot water sensor and then the remote operating valve 18 of the instant hot water boiler 1 is opened during its stopped condition.

IPC: D05B35/00
Filed: 1990-06-01
Abstract: PURPOSE:To diminish a relative slippage between the feed amount of a feed dog and the displacement of selvage sewing part produced by the rotation of a rotary disk and prevent puckering, by a method wherein rotating speed control signals are outputted from a rotating speed controller to a second motor, based on the reference rotating speed of a first motor. CONSTITUTION:When a relative slippage between the feed amount and the displacement of selvage sewing part 4A occurs during sewing operation, a controller 10c is manually operated to control pulse signals issued from a second pulse generator 10B, and a second motor 9 is cycled at a rotation speed corrected, according to the reference rotation speed of a first motor 8, so that said relative slippage can easily be absorbed and corrected. Thus, the second motor 9 is cycled at a corrected rotating speed so that the displacement (rotation angle) of the selvage sewing part 4A is not behind (angle of lag) nor ahead (angle of lead) the feed rate of a feed dog 3b. Therefore, puckering is certainly prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain the flat silver bromide grains having an aspect ratio controllable under wide ranges of temperature and halogen concentration at the time of mixing by epitaxially growing crystals composed mainly of silver bromide on seed crystals by using the seed crystals. SOLUTION: The flat grains are produced by epitaxially growing crystals composed mainly of the silver bromide on the seed crystals. The crystals composed mainly of the silver bromide are silver iodobromide or chloroiodobromide containing >=50 mol.% silver bromide. Preferably the seed crystals are silver iodide grains and, above all, the β type silver iodide grains belonging to the hexagonl system which are obtained by rendering the concentration of iodine ions in the mixed solution higher enough than that of silver ions in the solution. The sizes of the β type silver iodide grains to be used for the seed crystals may be optional. The silver iodide content of the produced flat grains is about 20 mol.% at most in the case of a photographic emulsion, and a suitable grain diameter is about 0.05-1 μmol.

Title: Control device of copying machine
Inventor: HAMAKAWA WATARU
IPC: G03G21/00
Filed: 1985-07-01
Abstract: PURPOSE:To improve the efficiency for interrupting copying while an automatic original transporting device is used by controlling a copying starting SW to a receivable condition and an original transporting starting SW to a reception prohibiting condition, when an interruption switch (SW) is operated and an interrupting copying condition is obtained. CONSTITUTION:When an interruption SW 77 is turned on, an interrupting signal falls down, and is transmitted from a CPU 1 of the copying-machine main body to the CPU of the automatic original transporting device. When the copying action to transport the original by an automatic original transporting device is selected for the original at the transporting device, the original in the surface copying condition is straight, the original in the rear surface copying condition is inverted, and any of the originals is discharged with the surface in the lower direction. The next original to stand by at the paper feeding part is also discharged in a straight way with the surface down, and an original transporting start SW is controlled to the reception prohibiting condition. Since a copying start SW 70 is in the reception allowable condition, the copying action is started by setting the interrupting original and turning on an SW 70. When the SW 77 is turned on again, the interrupting signal rises, the interrupting copying is released, and the reception prohibiting of the original transporting start SW is also released.
