Title: Apparatus for inspecting electric circuit having probe
Inventor: ATSUMI HARUO
IPC: G01R31/26
Filed: 1994-12-22
Abstract: PURPOSE: To easily and reliably connect electrode pad of an object to be inspected to pattern of an inspecting circuit by pressing the object by a pressing means in the direction of a substrate and pressing each probe to the pattern against elasticity. CONSTITUTION: An object 19 to be measured is positioned between respective probe supports 15, and the object 19 is inspected while it is pressed in the direction of a substrate 11 by a pressing means 23. At this time, the object 19 is pressed in the direction of the substrate 11 while it is positioned inside the support 15, and each electrode pad on a lower face of the object 19 is surely brought into contact with a tip of each corresponding probe 17. Since the tip of each probe 17 is pressed in the direction of the substrate 11 by each electrode pad, a bent slope of each probe 17 is bent toward the substrate 11 against its elasticity. As a result, the bent part of each probe strongly presses a pattern 13 on the substrate 11.  Thus, each electrode pad of the object 19 is easily and reliably connected to the pattern 13 for inspecting a circuit on the substrate 11 via the bent slope of each probe 17.

Title: Electrostatic copying machine
Inventor: SAKAMOTO HIROYUKI
IPC: G03G15/04
Filed: 1991-11-28
Abstract: PURPOSE:To increase the maximum number of copies per unit time at the time of unmagnified copying operation or copying operation with magnifications similar to the copying operation by increasing or decreasing a maximum voltage which can be applied to a document lighting lamp according to the projection magnifications of an optical means. CONSTITUTION:Before the electrostatic copying machine is forwarded, information for limiting the maximum voltage which can be applied to the document lighting lamp 22 is inputted to the fixed storage means 50 of a control means 54. Namely, the information for decreasing the maximum necessary illuminance of the document lighting lamp 22, i.e., the maximum necessary applied voltage as the projection magnifications are decreased from maximum magnifications factor to an unmagnification factor or increasing the maximum necessary applied voltage as the projection magnifications are decreased from the unmagnification factor to a minimum reduction factor is inputted to the fixed storage means 50. Consequently, when the projection magnifications are is equal or close to the unmagnification, the maximum voltage which can be applied to the document lighting lamp 22 is limited to a necessary voltage lower than a rated voltage to prevent an unnecessarily high voltage which is equal or close to the rated voltage from being applied to the document lighting lamp 22.

Abstract: PURPOSE:To enhance the speed and stability of erasing operation by forming row electrodes or column electrodes of a stripe form on respective insulating substrates, disposing these substrates to face each other across discharge gas spaces and coupling the column electrodes via a high resistance layer to these discharge gas spaces. CONSTITUTION:The insulating substrates 1, 2 consisting of glass are arranged in parallel via ribs 9 across the discharge gas spaces 6 in which a gaseous mixture composed of He and Xe is held. The row electrodes 7 of the stripe form are formed on the surface on the discharge as space side of the insulating substrate 1 and an insulating layer 3 consisting of low melting paint leaded glass and a protective layer 5 consisting of MgO are laminated thereon. The column electrodes 8 of the stripe form are formed in the surface of the discharge gas space side of the insulating substrate 2 in the direction orthogonal with the row electrodes 7. Phosphors 10 are formed in the positions corresponding to the pixels on the insulating layer 4 laminated thereon. The common electrode of the strip form are coupled via resistor layers 15 consisting essentially of ruthenium oxide to the discharge gas spaces 6. Then, the emission of the electron from a low resistance layer 15 rises in addition to recombination of the charges in the discharge spaces. The erasing action is thus made fast and sure.

Abstract: PURPOSE:To rapidly and highly accurately regulate an output voltage by cutting off the branch of a conductive pattern to regulate a photodetecting signal outputted from a photodiode array body and then regulating the electric phase of a two-phase signal. CONSTITUTION:Since the array bodies P<1>k, P<2>k of a unit photodetecting part Qk mutually form 90 deg. array phase difference, photodetecting signals I<1>k, I<2>k mutually forming 90 deg. electric phase difference correspondingly to the rotational angle theta of a rotated rotational disk 8 are outputted from respective array bodies P<1>k, P<2>k. Thereby, a photodetecting signal becomes the vector sum of the signals I<1>k, I<2>k. Since the corresponding array bodies P<1>1, P<1>3 and P<2>1, P<2>3 of the 1st and 3rd unit photodetecting parts Q1, Q3 mutually form 180 deg. array phase differ ence, photodetecting signals I1, I3 formed correspondingly to the rotation of the disk 8 mutually form 180 deg. electric phase difference. Thereby, the DC offset part of the signals I1, I3 is offset by differentially amplifying the signals I1, I3 and the 1st phase signal can be obtained. Similarly, the 2nd phase signal can be obtained by differentially amplifying signals I2, I4.
