Title: Exhaust gas denitration device of diesel engine
Inventor: WAKAMOTO KOTARO
IPC: F01N3/20
Filed: 1994-09-14
Abstract: PURPOSE: To provide the exhaust gas denitration device of a diesel engine by which the hydrocarbon component of a reducing agent in exhaust gas led to flow into a catalyst layer can be made constant regardless of any operation condition of an engine. CONSTITUTION: Exhaust gas 16 led to flow into an exhaust pipe 12 is cooled down to a predetermined temperature by a condenser 40. After that, the fuel of a reducing agent is added to the exhaust gas 16 from a fuel adding nozzle 18 attached to the exhaust pipe 12. This fuel is thermally decomposed into the hydrocarbon of a low reducing agent by the heat of the exhaust gas 16, is led to flow into a catalyst layer 26 together with the exhaust gas 16 and reacts to NOx in the exhaust gas 16 by the catalytic action of the catalyst layer 26 so that the NOx is deoxidized and is purified. Meanwhile, a controller 30 controls the cooling ability of the condenser 40 on the basis of exhaust gas temperature in a position where fuel detected by a first temperature sensor 56 is added, and controls the exhaust gas temperature in the position where the fuel is added, to a predetermined value.

Title: Optical receiver
Inventor: YAMAZAKI DAISUKE
IPC: H04B10/50
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To avoid being buried in noise by connecting to a photodetective element, removing low-frequency control signal components from a current signal through the use of a signal corresponding to a reproduced low frequency control signal and then reproducing a data signal so as to reproduce both of the low-frequency control signal and the data signal by sufficient amplitude when a superimposed optical signal is inputted. SOLUTION: When the photodetective element 1 receives a signal obtained by superimposing the low-frequency control signal and the data signal, a corresponding current flows through a resistor R1 and only the low frequency control signal is envelope-detected by an envelope detector consisting of a transistor Tr2, etc., and outputted. On the other hand, a transistor Tr3, a level shift diode 4 and resistors R3 and R4 constitute a low frequency control signal removing part. Then, the drop of voltage caused by the flowing of the current I1 of the low frequency control signal through the resistor R1 is transmitted to the cathode of the diode 4 and the current of only the data signal completely removed of the low frequency control signal components is inputted to a preamplifier 5.

Abstract: PURPOSE:To regenerate by an ordinary television set by mixing both a video signal and an audio signal inputted from each input terminal to form a source signal for television and mixing the signal with the 1st part oscillation signal by the 1st mixer and with the 2nd part oscillation signal by the 2nd mixer. CONSTITUTION:A signal transmitted to the mixer 7 through a band pass filter 6 is mixed with the 1st part oscillation signal to be converted to an intermediate frequency signal having higher frequency than that in TV signal band, and then reaches the 2nd mixer 22 through the band pass filter 21. Frequency signal outputted from frequency separator 9 is inputted in a phase comparator 23 in the 2nd part oscillation circuit L2. Signal outputted from the phase comparator 23 is given to a voltage control type oscillator 25 through a low pass filter. The oscillator 25 oscillates a signal having a frequency corresponding to the signal to give it to a mixer 22 as the 2nd part oscillation signal. The frequency of the intermediate frequency signal inputted through the band pass filter 21 is converted by the 2nd part oscillation signal, to become the frequency of one channel signals among many TV channels.

Title: Arithmetic processor
Inventor: YOSHITAKE AKIHIRO
IPC: G06F7/00
Filed: 1990-09-19
Abstract: PURPOSE:To execute the branch processing at a high speed and to decrease the overhead at the time of condition branch instruction by executing a branch decision at the time point when an instruction train which is being executed before a condition branch instruction executed in a pipeline defines a condition code to be referred to be the condition branch instruction, at the time of executing the condition branch instruction. CONSTITUTION:In the case an instruction Prel does not change a condition code referred to by a condition branch instruction, a branch decision is executed by referring to a condition code defined by executing an instruction Pre2. That is, the branch decision (CHK) is executed in a stage of a fetch (IF) of a branch destination instruction by a condition branch instruction. In such a way, comparing with a conventional example, the overhead can be decreased by a one-stage portion, and the branch processing of a high speed can be realized by increasing a small number of hardware.

IPC: H04N1/393
Filed: 1986-10-17
Abstract: PURPOSE:To simplify registered information retrieving works, by reading out and displaying reduced picture information while a designating key is in an operated state and reading out and displaying picture information corresponding to the displayed reduced picture information from a storing area by cancelling the designating operation of a specific retrieval designating key. CONSTITUTION:When the depressing operation of a search key is cancelled, a CPU 3 discriminates that the page information displayed on a CRT 2 is selected at the time of cancellation. As a result, the primary information (picture information) corresponding to the selected page information written in the primary information storing area of a storage device 10 is retrieved and read out. The primary information read out from the storage device 10 is once sent to a memory 5 and, thereafter, the primary information of the memory 5 is returned to the original data by means of a compressing/expanding circuit 8. Then the CPU 3 outputs a thinning (reduction) displaying instruction to a control circuit 4 so as to cause the control circuit 4 to make a thinning processing on the 12 mm X 12 mm primary information to 1/2 X1/2. As a result, all of the information on A4-sized paper is reduced to one page of primary information and displayed on the CRT 2.

Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To surely detect a watermark. SOLUTION: A watermark read from a watermark pattern holding memory 32 is supplied to an evaluated value calculation device 31-1 with a shift amount 0, which is supplied to the evaluated value calculator 31-2 by being shifted for the shift amount (i) and supplied to the evaluated value calculator 31-3 by being shifted for the shift amount (j). In the evaluated value calculator 31-1, an evaluated value is calculated by using a watermark pattern which is not shifted. In the evaluated value calculators 31-2 and 31-3, the evaluated value is computed by using the watermark pattern shifted for the shift amount (i) or the shift amount (j). An evaluated value comparator 33 sets the evaluated value of the intermediate value among the evaluated values outputted by the evaluated value calculators 31-1-31-3 as a standard evaluated value.  The evaluated value comparator 33 compares the absolute value of a difference between the reference value and the evaluated value of the shift amount 0 with a prescribed threshold and discriminates that the watermark has been added, when absolute value is larger than the threshold.
