Inventor: SUMI KATSUTO
IPC: H04N1/19
Filed: 1990-09-03
Abstract: PURPOSE:To easily detect deviation of joints of plural photoelectric conversion elements by including a 1st process leading out an image pickup signal, a 2nd process leading out a visual output picture and a 3rd process superimposing an output picture and a grating pattern and detecting the joint deviation in the scanning direction of joints of plural photoelectric conversion elements depending on the state of obtained moire stripes. CONSTITUTION:At first, a test chart 18 is carried in a subscanning direction (in a direction of arrow X) at a picture scanning section 10 and a picture read section 12 reads longitudinal lines 22 and lateral lines 24. In an output picture, the longitudinal lines 22 and the lateral lines 24 recorded on the test chart 18 are overlapped while being tilted by a tilt angle theta. In this case, a moire stripe is caused in the reproduction picture of the longitudinal lines 22 based on a spatial frequency caused by a pitch of the longitudinal lines 22, a spatial frequency caused by a pitch of an output picture with nonmagnification output and the tilt angle theta. Similarly, a moire strip is caused on the reproduction picture of the lateral lines 24.

Abstract: PURPOSE:To increase the scanning speed of a reader by providing a dividing circuit with an operational amplifier, fixed negative feedback resistance, plural bit- weighted input resistors, and switch element which is turned on and off under the control of the output of a ditital memory, and speeding up the response of the dividing circuit. CONSTITUTION:Switches S0-S3 are connected to resistance R, 2R, 4R, and 8R of the dividing circuit 32 in parallel. The switches S0-S3 are made of, for example, FETs. When a light source 11 scans on a white reflecting plate 12, a storage designating STROBE input turned to ''1'' and the switches S0-S3 are all turned off, so the gain G of the dividing circuit 35 is G=31R/(R+2R+4R+ 8R+16R)=1. Namely, when the light source 11 scans on the white reflecting plate 12, an image signal applied from a DC reproducing circuit 31 to the dividing circuit 32 is outputted as it is and applied to a texture detector 33 and an A/D converter 34. The texture detector 33 holds the maximum level of the input, i.e. maximum value of the white level of reflection by the white reflecting plate 12 as a reference level REF and applied to the A/D converter 34.

Title: Data processor
Inventor: IWATA SHUNICHI
IPC: G06F12/08
Filed: 1986-10-01
Abstract: PURPOSE:To attain the earlier start of the decoding of an instruction executed next to a branch instruction by making the address tag of a branch target instruction buffer as the address of the instruction executed immediately before the branch instruction. CONSTITUTION:When the instruction code is fetched from an instruction perfecting queue 1 into an instruction decoding part 2, an instruction code is started and the inside of a branch target instruction buffer A4 is retrieved by the address value. When the instruction during the present decoding is the instruction to disturb the flow of the instruction executed recently, the data are registered to the branch target instruction buffer A4, therefore, in retrieving, the entry is hit. In this time, since the retrieving in the branch target instruction buffer A4 is started by the address of the instruction executed immediately before the branch instruction, the retrieving is started earlier than when the retrieving is started by the address of the branch instruction. Thus, since the preparations to fetch the instruction code 10 of the hit entry into the instruction decoding part 2 can be executed earlier, the instruction code 10 of the jump destination can be fetched into the instruction decoding part 2 immediately after the decoding of the branch instruction is completed.

IPC: H05K3/46
Filed: 1989-09-11
Abstract: PURPOSE:To obtain a multilayered copper-plated laminated board which has a small coefficient of contraction and no difference in coefficient of contraction between the longitudinal and transversal directions and is improved in dimensional accuracy and stability after work by alternately piling up internal layer sheets and prepreg sheets in a state where the orientation of the base material of the internal layer sheets is made orthogonal to that of the base material of the prepreg sheets. CONSTITUTION:Internal layer sheets 4 and 8 and prepreg sheets 1 and 7 are alternately piled up in a state where the orientation of the base material of the plates 4 and 8 is made orthogonal to that of the base material of the sheets 1 and 7. When a laminated board is manufactured is such way, the ratio of the coefficient of contraction in the longitudinal direction of the board to that in the transversal direction can be reduced to 1 as much as possible and, at the same time, the absolute values of the coefficients can be reduced. In addition, when the orientation of the base material of the prepreg sheets 1 and 7 is made parallel to the long side of the board rather than the short side, the abovementioned effect can be exerted more efficiently. Moreover, when the laminated board is heated at 150 deg.C for more than one hour before circuits are formed on the internal layer sheets 4 and 8, a multilayered copper-plated laminated board which is small in coefficient of contraction and excellent in dimensional stability can be obtained.

Abstract: PURPOSE:To maintain the linearity of traverse speed of an objective lens and to control an optical pickup with high accuracy by attaching polarity by differentiating and rectifying a triangular wave shape track error signal converted from a sine wave shape track error signal. CONSTITUTION:By converting the sine wave shape track error signal to a digital value by an A/D converter 7 and inputting the digital value to a ROM8 as an address signal, the digital value corresponding to the triangular wave shape track error signal is read out. By converting the digital value to the triangular wave shape track error signal by a D/A converter 9, differentiating by a differentiator 10, and rectifying by a full-wave rectifier 11, the absolute signal of the speed of the objective lens which traverses a track on a recording medium is detected. In such a way, since the linearity of the signal and the actual traverse speed of the object lens can be maintained, it is possible to control the objective lens of the optical pickup with high accuracy.

Abstract: PURPOSE:To perform air-fuel ratio control in a highly accurate manner as well as to improve drivability ever so better, by seeking for a compensating injection quantity according to a primary delayed quantity in the engine's load value detected by a load value detecting device, while compensating the compensating injection quantity upon adding or subtracting it to or from a basic injection quantity.

Next, judging of positive or negative in the value DELTAT, when DELTAT>0 is the case, compensating pulse width DELTAt is set to an increment compensation value E commensurate to the value DELTAT, and when DELTAT<0 is the case, it is set to a decrement compensation value D commensurate to the value DELTAT, respectively. And, according to this compensating pulse width DELTAt, the basic injection pulse width (t) is compensated.

Inventor: OGAWA KATSUHISA
IPC: H04N5/335
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To take out the photoelectric conversion output with high linearity by reducing the W/L size of a depression type MOS transistor TR used for a constant current source in comparison with the W/L size of a depression type MOS TR used for a pixel source follower. SOLUTION: When a 1st depression type MOS TR 3 has been selected by a selection means, the W/L (W: gate width, L: channel length) ratio (channel ratio) of a 2nd depression type MOS TR 6 which absorbs the bias current of the TR 3 is reduced compared with the W/L ratio of the TR 3. That is, Vgs of the TR 3 is set at the value that is biased to Ov. As a result, the gate-source voltage never drops and the dynamic range of signal output is extended despite a low voltage operation to secure a sufficient signal amplitude.
