Filed: 1988-01-28
Abstract: PURPOSE:To enable dispersion of a LED driving current of each chip to be equalized with an operational amplifier by making all chips equal in external resistance value, by establishing the operational amplifier, a transistor for monitor, an output transistor for monitor, and an outside fitting external resistance. CONSTITUTION:Since a transistor for monitor 37 is always in an on state, an output transistor for monitor becomes also in an on state, and a source current flows to a ground through an internal resistance 39 and an external resistance 33. A terminal 33 which is a junction of the resistances 39, 33 is kept at a reference voltage Vref to be impressed to a terminal 32 by action of an operational amplifier 36, and I flowing from the terminal 33 to the ground is Vref/R. When another driving circuit to be connected to a LED comes in an on state, the transistors 37, 38 and the internal resistance 39, and transistors 40a, 41 and an internal resistance 42 come wholly in the same operation state. When the same voltage as a LED on voltage of a LED array is selected as the reference voltage Vref herein, a current of Vref/R flows to total LED of the same structure.

Filed: 1979-02-20
Abstract: PURPOSE:To realize a simple-constitution circuit which features a high-speed operation and small amount of power consumption at the queuing time, by securing both the capacitor charging concurrently with application of the input voltage and the bootstrap function via the capacitor at one time. CONSTITUTION:MOSFET5 is connected between point A and the earth point, and the gate is connected to input terminal C along with the gate of MOSFET4. The high-level voltage is always applied to terminal C, and FET4 and 5 are ON. And voltage VA and VB of point A and output terminal B are at the earth potential each. When input voltage VC to terminal C becomes to a low level, voltage VA at point A increases quickly to make MOSFET2 conduct. And then voltage VA is raised up to secure the ON state for FET2, and output voltage VB holds VDD. When voltage VC turns to a high level again, both voltage VB and VA are set to the earth potential again.

Title: Magnification varying method of zoom lens
Inventor: MATSUSHITA TAKASHI
IPC: G02B15/20
Filed: 1985-02-04
Abstract: PURPOSE:To extend the variable magnification range of a lens by moving the first and the second lens groups from a position near the telephoto side of the first variable magnification along moving locus different from those for the first variable magnification while interposing the displacement point of reciprocation of the first lens group and performing the second variable magnification thereby. CONSTITUTION:The first lens group I of the first variable magnification is moved along the moving locus different from that for the first variable magnification, for example, from the position of a telephoto end T near the displacement point of reciprocation of the first lens groups I to the position of a supertelephoto end TT in the direction of an objective to perform the second variable magnification, and the variable magnification range is extended as the whole. For the purpose of compensating aberrations well throughout the variable magnification range including the first variable magnification and the second variable magnification and shortening the overall length of the zoom lens, it is desirable that the condition of a formula is satisfied where Z1 is the variable magnification ratio of the first variable magnification and Z is the resultant variable magnification ratio of the first and the second variable magnification.

Title: Contact probe and its manufacture, and probe apparatus having contact probe
Inventor: TAI AKIRA
IPC: H01L21/66
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To improve contact accuracy by uniforming tips of contact pins in height without grinding and making the contact pins touch a pad at the same time. SOLUTION: Contact pins 3a are integrally molded with the use of a mask exposure technique in a state with tip parts (tungsten balls in this case) 3T projecting perpendicularly downward from main body parts 3K. Therefore, the tip parts 3T are highly accurate in size and uniform in height, eliminating conventional grinding. When a pad is formed of, e.g. soft gold, it is enough to set a contact probe in parallel to a pad face and carry out overdriving, whereby the tip parts 3T remove only an oxidization film on the pad face and surely touch an undercoat of the pad. Since tips of the pins are not required to be ground and the contact probe is not required to be inclined when arranged, parts, jigs, etc., for fitting the contact probe are simplified in structure as compared with the prior art.

Abstract: PURPOSE:To prevent a reflecting member from being deformed by the shock when it is transported by providing stopper members near the reflecting member. CONSTITUTION:A fluorescent lamp holder 22 is attachably and detachably held by a first mirror table 23 holding a first mirror M1. The reflecting member 24 is arranged to face a fluorescent lamp 21 as an illuminating member, indirectly illuminates an original and is made of high brightness alloy. The hight of the top parts 25a' and 25b' of the stopper members 25a and 25b are the same as that of the top part 24' of the reflecting member 24. At the moment that the shock is given, a placing table drops and collides with the hight of the top parts of the reflecting member 24 and stopper members 25a and 25b, but this collision power is absorbed by the flexture of the first mirror table 23 and rails 8a and 8b. Thus, if the placing table of an image reader collides with the reflecting member 24, the placing table does not give power enough to collide to the reflecting member 24.
