Title: Clock circuit
Inventor: ISHIKAWA TORU
IPC: H03K5/05
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a clock circuit capable of improving the worst state (a duty ratio is deviated from 50% and the rise time of a clock is also decelerated) of a clock signal by averaging the deterioration of a clock waveform between the output of a clock generator and the terminal side of a signal returned through a loop. SOLUTION: A clock signal outputted from a clock generation circuit 6 is supplied to devices 1 to 3 through a loop-like clock wire 4. The clock signal returned up to a terminal resistor 8 is inputted to a duty control circuit 7, which controls the circuit 6 so that the duty ratio of the returned clock signal becomes 50%.

Title: Photodetector module
Inventor: HOSHINA YOSHINORI
IPC: H01P3/08
Filed: 1993-04-01
Abstract: PURPOSE:To reduce the parallel resonance of the inductance of a conductor pattern and the parasitic capacitance between the conductor and ground to eliminate peaks and dips in characteristic curves of an optical module by inserting a chip capacitor between an optical element and ground for decreasing the impedance of a bias source. CONSTITUTION:A ground layer 11 is formed on a surface of a chip carrier 12 where a photodetector is attached. A capacitor 3 is placed between the photodetector 1 and the ground layer 11. Since C1 makes an a.c. short circuit, the parallel resonance of C1, L2, ST2 and LB is prevented, thus eliminating dip B. If C1 is increased, Q of a peak A due to the series resonance of LB, ST1, L1, and C3, CA, C1 is lowered, thus lowering peaks. The dielectric layer under striplines of the chip carrier 12 is made thin to decrease the stripline- ground capacitance so that the width of the stripline may be optimized.

Abstract: PURPOSE:To provide excellent thermal conductivity and electric conductivity of a lead, to provide sufficiently high hardness and to avoid the change in hardness even though heat history is received, by forming the lead material of an electronic part, in which semiconductor pellet is sealed, by copper alloy wire including chromium. CONSTITUTION:In a glass molded diode, a silicon pellet 1 having a P-N junction is held and fixed to an electrode 2 made of molybdenum or tungsten through aluminum solder 3. A copper alloy lead 4 is welded to the electrode 2. The pellet 1 is sealed by a glass 5. The lead 4 is constituted by the copper alloy comprising 0.5-1.5wt% chromium and copper for the remaining part. When the chromium is less than 0.5wt%, the required hardness is not obtained when a heat history is received and annealing is performed. When the chromium is more than 1.5wt%, the electric conductivity and the thermal conductivity become lower than those of copper. Therefore the part is not practical.

Title: Character recognition device
Inventor: NANBU HIDETOSHI
IPC: G06K9/62
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to accurately measure similarity to dictionary data and to improve the recognition rate by matching data after correcting a position using a stepwise shifting path for a shifting process for an oblique direction pattern. SOLUTION: A feature extraction device 7 decomposes input data into longitudinal, lateral, and oblique segments. A recognition processing device 9 matches the input data to the dictionary data 8 as to the respective decomposed direction patterns. At this time, a 'shift' is applied for the longitudinal and lateral direction patterns at right angles to the directions of the patterns. For the oblique patterns, a path for a stepwise 'shift' along an oblique direction perpendicular to the direction of the patterns is used. Consequently, the matching can surely be performed and the recognition rate can be improved. In this case, the same effect can be obtained by shifting pixels in even columns in odd rows to even columns and pixels in odd columns in even rows to even columns.
