Title: Method and circuit for low noise reading of column transfer optical photosensitive matrix
Inventor: MARUKU ARUKU
IPC: H04N5/217
Filed: 1988-12-29
Abstract: PURPOSE: To reduce noise that is introduced at the time of transferring electric charge from a matrix to an output shift register by forming a replica charge against the initial charge at a prescribed ratio, after each motion for transferring a charge quantity from an input conductor to an intermediate storage zone, and successively executing a motion for reproducing the charge to the input conductor. CONSTITUTION: A charge quantity to be read is transferred N times (N is an integer of 2 or above) from a column Cj to an intermediate storage zone, duplicating this charge Qs by a comparator AMP2 each time, reproducing the initial charge Qs in the input column Cj each time, setting a charge quantity proportionate to the sum of the charge Qs transferred each time using the duplicated charge Qs*, and in the end, transferring to the output register RDS(read only strage) the charge quantity proportionate to the sum of the charge Qs* transferred to the intermediate zone. Consequently, noise introduced during each transfer is reduced to the extent of losing a correlation mutually.

Title: Appearance inspection device
Inventor: TANTANI YASUSHI
IPC: G01B11/30
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a higher degree of accuracy for detecting defects in a display substrate with a three-dimensional structure formed thereon by inspecting the same. SOLUTION: An appearance inspection device for detecting defects occurred in a construction layer (barrier rib 3) of the substrate by illuminating the surface of the substrate, detecting a reflected light from the surface of the substrate by a line sensor S (or an area sensor) and treating variations in the intensity with a specific algorithm comprises an illumination utilizing a parallel incident light at a specific angle to the substrate or a diffused light. The illumination of the parallel light nearly perpendicular to the substrate may minimize a shadow from the structure itself and eliminate the emphasis of the reflected light, thereby preventing an error in detecting defects. The diffused light may minimize the shadow generated from the structure itself or the reflected light at the edge of the defects.

Title: Backup power unit
Inventor: ISHIDA NOBORU
IPC: G06F1/26
Filed: 1989-12-26
Abstract: PURPOSE:To curtail the power consumption by providing a second transistor which is turned ON/OFF by an operating signal from a microcomputer, forms a bypass circuit and increases/decreases a base current supplied to a first transistor. CONSTITUTION:When a power source switch 14 is turned off, and set to a second state that an operation of a microcomputer 12 stops, the microcomputer 12 judges this state and turns off a CNT signal. In such a state, a transistor 13 is nonconductive and a second transistor 21 also becomes nonconductive, therefore, as for a voltage applied to the emitter of the transistor 21, a voltage drop caused by a resistor 22 is generated, and a potential difference is held between the emitter and the collector. A voltage supplied to a constant-voltage diode 24 through a resistor 23 from the collector is a value being lower than the Zener level of the constant-voltage diode 24, and this voltage is supplied to a base of a first transistor 25. Subsequently, the transistor 25 outputs the second current of a smaller value than that of a first current to the emitter side, and supplies it to the terminal 12a of the microcomputer 12. In such a manner, the power of the backup power source can be curtailed.
