Title: Device for synthesizing and decomposing signal
Inventor: YAMAZAKI SHOICHIRO
IPC: G10L19/02
Filed: 1994-02-28
Abstract: PURPOSE:To hiererchically decompose two or more integers signals to a conversion area and to synthesize them from the conversion area with the same kinds of a synthesizer group, a decomposer group by synthesizing decomposing the signal on a finite body based on a Chinese remainder theorem. CONSTITUTION:Four pieces of signals bi(X) (i=0, 1, 2, 3) are shown by the combination of a polynomial bi, k (X) of the third to the most. When conversion functions f1(X), f0(X) consisting of a fourth irreducible polynomial are allocated to the b30(X), b20(X) respectively, and are synthesized by a synthesizer 1 based on the Chinese remainder theorem, an eight bits signal of the polynomial of the seventh to the most is generated. The signal is distributed by a distributor 1, and are synthesized with the b10(X), b11(X) by synthesizers 2, 3, and further, are distributed by the distributors 2, 3, and are synthesized with the b00(X), b01(X), b02(X), b03(X) by the synthesizers 4-7, and four pieces of eight bit signals are generated. Finally, when the signals are combined by a combiner 1, a B0(X) (32 bits) is synthesized. Then, the B0(X) is decomposed into eight pieces of signals b30(X), b20(X), b10(X), b11(X), b00(X), b01(X), b02(X), b03(X) on the decomposing side.

Title: Ink jet recorder
Inventor: YASUTOMI HIDEO
IPC: B41J2/045
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To prevent the image quality from degrading by driving a piezoelectric element with an applying voltage varying smoothly with time based on a specified data and recording an image by flying ink droplets. SOLUTION: A head jet part drive section 105 comprises an inverted amplification circuit 1051, and a drive circuit 1052 wherein an image signal Vin is amplified through the inverted amplification circuit 1051 to produce a signal Vn which is then passed through the drive circuit 1052 to produce a smooth drive signal Vout for driving a piezoelectric element. The waveform comprises five waveforms having different maximum amplitude of 10, 15, 20, 25 and 30V wherein a larger amplitude is employed for printing a larger dot and dots of different size are printed by applying driving voltage of different amplitude to the piezoelectric element thus representing a half tone. Since the driving voltage varies smoothly with time, degradation of image quality can be prevented.

Title: Resin-sealed semiconductor device and its manufacture
Inventor: NAKAZAWA TSUTOMU
IPC: H01L21/52
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the strength against package crackings which are developed at the time of mounting. SOLUTION: In order to fix a semiconductor chip 11 to a lead frame 12, insulating resin such as polyimide resin 15 is applied over the side surfaces of the corner parts and the parts of the rear surface of the semiconductor chip 11 for fixing. As the semiconductor chip 11 is fixed to the lead frame 12 with the polyimide resin 15 which is applied over the side surfaces and the rear surface, the separation of the boundary between the rear surface of the semiconductor chip 11 and a resin package 14 is hardly produced and, even if the resin package 14 absorbs moisture, expansion by moisture vaporization is not produced. With this constitution, the strength against package crackings which are developed at the time of mounting can be improved.

Title: Moving picture encoding method and its device
Inventor: NAKAYA YUICHIRO
IPC: H04N19/154
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent accumulation of errors and to improve the quality of a reproduced picture by using a minus rounding method for a second movement compensation when a plus rounding method is used for a first movement compensation and using the plus rounding method for the second movement compensation when the minus rounding method is used for the first movement compensation. SOLUTION: A frame P where block matching of semi-picture element precision is executed and movement compensation using plus rounding is applied is called as a frame P+, and a frame P where movement compensation using minus rounding is applied is called as a frame P-. The absolute value of the expectation of a rounding error in the P-frame becomes equal to that of the P+ frame, but with an opposite sign. Thus, the absolute value of the P- frame becomes equal to that of the P+ frame but with the opposite sign on a time base. When the P+ frame and the P- frame are caused to alternately appear on the time base, accumulation of rounding errors is prevented.

Title: Wet flue gas desulfurization method
Inventor: WATABE TERUTSUGU
IPC: B01D53/50
Filed: 1991-01-31
Abstract: PURPOSE:To secure a stabilized absorbent slurry composition irrespective of the variations in the SO2 content at the inlet of an absorption tower and to recover gypsum having a large grain diameter by decreasing the supply of oxidizing air as the sulfur oxide content increases at the inlet of the tower or when the gypsum separator is vibrated. CONSTITUTION:A Ca-based compd. slurry stored in a circulating tank 7 set at the lower part of an absorption tower 4 is sprayed into the tower 4 and brought into contact with the waste gas to remove the SOX contained in the waste gas. Meanwhile, air is blown into the slurry in the tank 7 to oxidize the CaSO3 generated due to the absorption of SOX by the Ca-based compd. In this case, the supply of oxidizing air to the slurry in the tank 7 is decreased when the SO2 content at the inlet of the tower 4 exceeds a specified value or a gypsum separator 14 is vibrated, hence the composition of the absorbent slurry is stabilized in the tower 4, and the gypsum having a large grain diameter is recovered.
