Title: Noise reduction circuit
Inventor: MINE TADAKI
IPC: H04N5/378
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To provide a noise reduction circuit by which an excellent noise reduction effect is obtained with low power even in the case of a charge coupling element with high resolution. SOLUTION: A delay circuit 24 delays an output signal Ta of a CCD 20, a pulse generating circuit 25 outputs a pulse signal Tc whose period is the same period as a CCD output signal Ta and whose phase at a high level is partly in duplicate with a signal level period (v) of the CCD output signal, a 1st NAM circuit 21 selects the CCD output signal Ta or the pulse signal Tc whose level is lower, and a 2nd NAM circuit 22 selects delay signal Tb of the delay circuit 24 or the pulse signal Tc which has a lower level. Then a differential circuit 26 takes a difference between a mixed signal of the 1st NAM circuit 21 and a mixed signal Td of the 2nd NAM circuit 22. A delay time τof the delay circuit 24 is overlapped with a feed-through level period of the delay signal Tb with respect to a signal level period (v) of the CCD output signal Ta.

Title: Psk carrier signal reproducing device
Inventor: GOTO TETSUO
IPC: H04L27/227
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To execute demodulation at a high bit rate, namely, to accelerate modulation speed without considerably changing a conventional circuit configuration. SOLUTION: Mixers 2a and 2b synchronously detect a PSK carrier signal by a reference carrier signal outputted from VCO 8 and the synchronism detection output is passed through low-pass filters 3a and 3b so as to obtain a fundamental band modulation signal (I/Q signal). It is inputted to A/D converters 4a and 4b. A clock signal synchronized with the fundamental band modulation signal is frequency-divided into 1/N by a frequency divider 11. It is set to be the sampling signal of the A/D converters 4a and 4b and is outputted. The fundamental band modulation signals which are A/D-converted are phase- compared by a phase difference detector 5 and a phase difference signal is outputted. The phase difference signal is fed back and inputted to VCO 8 through LPF 7 and the oscillation frequency is controlled. Thus, a reference carrier signal is reproduced and outputted.

IPC: F02D41/00
Filed: 1984-11-02
Abstract: PURPOSE:To prevent engine stopping by changing control of a control valve into high duty ratio when engine load is suddenly increased during control of the valve in low duty ratio, in a machine in which idle rotational speed is controlled by controlling opening of the control valve in a bypass circuit bypassing a throttle valve. CONSTITUTION:An idle rotational speed control device interposes, an idle speed control valve 48 whose air amount characteristic and a duty ratio in low duty ratio are not linear and the characteristic in high duty ratio is linear, in a bypass circuit 47 provided so as to bypass a throttle valve 4. And in idle running time, the control valve 48 is subjected to feedback control so as to converge actual rotational speed to an objective idle rotational speed set according to the engine running condition. In this case, when engine rotational speed is decreased due to sudden increase of load under the condition where opening control of the control valve 48 is made in a low duty ratio range, the duty ratio is controlled so as to be transferred to the high duty ratio range.

Title: Mouse pad for optical mouse
Inventor: KATO HIROSHI
IPC: G06F3/039
Filed: 1988-09-14
Abstract: PURPOSE:To easily position a cursor in the vertical direction with a mouse by forming a line group for detecting the moving quantity of the mouse in the lateral direction of a group of straight lines radially arranged from a center below the line group. CONSTITUTION:A line 2 for detecting the vertical movement of a mouse and lines 1 for detecting lateral movement of the mouse are provided on a mouse pad 3. The line 1 is a radius vector and the distance (r) between the center of the vector and that of the mouse pad is set within a range of 27-50cm by adding the horizontal length from shoulder to elbows of human's bodies to the average length of human's arms from elbow to palm centers. Accordingly, the number of times of crossing the line 1 of a lateral movement detecting section in the detecting section of the mouse is reduced when the mouse is moved in the front-rear direction by the bending movement of elbows. Therefore, a cursor can be positioned easily on a screen, since the cursor vertically moves with less movement in the lateral direction.

Title: Pressure controlling method for nuclear reactor
Inventor: UDAGAWA KAZUYUKI
IPC: G21D3/08
Filed: 1989-09-07
Abstract: PURPOSE:To enable suppression of a water level changing of a nuclear reactor by decreasing a pressure changing rate gradually and by getting a target pressure value close to a certain value, when a changing rate of reactor water temperature calculated from a measured value of the reactor water temperature, differs from a predetermined specific value. CONSTITUTION:In case that a pressure setting value is set by an automatic calculator, coolant temperature theta is read in a course of depressurization at a specific time interval and a temperature changing rate theta ' of a coolant is calculated. After that, an absolute value of the changing rate theta ' is compared with the predetermined target value theta '0. When the absolute value of the chang ing rate theta ' is larger than the target value theta '0, a pressure changing rate is made to decrease gradually and a target pressure value is made to get gradually close to a certain value. In this situation, when being shifted from a depressurization process to a constant pressure controlling one, with a constant pressure changing rate, the pressure setting value is made to change gradually by a function of a digital filter. With this reason, a turbine by-pass valve does not close suddenly and therefore a changing of a reactor water level can be well suppressed.

Title: Arithmetic processor
Inventor: KANEKURA HIROSHI
IPC: G06F7/76
Filed: 1991-09-12
Abstract: PURPOSE:To round a value to the maximum or minimum one capable of expression within the range of the operation accuracy by providing a detection means detecting the overflow and underflow due to the operation result and a rounding processing means rounding the operation result after the overflow and the underflow processing. CONSTITUTION:A detection means 2 receives a signal from an operation means 1, judging a positive or negative overflow from the combination of the highest two bits. In the case of the expression of the complement 2, the positive overflow is judged when the highest two bits are '01', and the negative overflow is judged when '10'. The detection means 2 sends a signal to a rounding processing means 3 according to the detection result. The rounding processing means 3 sets the output value to the positive maximum value at the time of overflow and to the negative maximum value at the time of underflow. Thus, the color missing at the time of a video signal processing and the sound missing at the time of a voice signal processing can be prevented by resetting the operation result.
