Title: Amplifying circuit
Inventor: HIGASHIYAMA NAOTOSHI
IPC: H03F1/30
Filed: 1980-07-23
Abstract: PURPOSE:To increase the eliminating ratio of power supply voltage ripple, by minimizing the power supply voltage ripple component at the point of collector output of the 1st-stage transistor in a minor signal amplifying circuit having the active load. CONSTITUTION:The input signal applied to a terminal 25 is supplied to a transistor (TR)1. The collector of the TR1 is connected to the TR7. The input signal supplied to the TR1 is delivered from a point 27 of connection between the emitters of TR10 and TR11 that form an SEPP circuit and at the same time fed back to a terminal 28 to set the DC potential. The collector of the TR1 is furthermore connected to a power supply voltage supply terminal 26 via a constant current output circuit 102. On the other hand, the output of a constant current output circuit 103 passes through a bias compensating circuit 106 and is inverted by a current Miller circuit 101 to be applied to the emitter of the TR1. The base of the TR1 is connected to the circuit 106 via a resistance 17 and then to a bias circuit 107. In such way, the equal voltage is secured between the collector and the base of TR3 and TR4 of the circuits 102 and 103, and thus the noise component is minimized at the collector output point of the TR1.

Abstract: PURPOSE:To facilitate the adjusting of the height of a mount rail by a method wherein a wheel shaft, engaged with a screw rod, is provided with ascending or descending motion along the screw rod by the one-direction rotation of the screw rod to generate descending or ascending motion in a transfer table as the reaction of the motion of the wheel shaft. CONSTITUTION:When error is generated in height between the mount rail 2 of a transfer table 1 and the running rail of the same table 1, a nut 14 is loosened slightly to put an adjusting bolt 13 into rotatable condition. When the mount rail 2 is higher, for example, the bolt 13 is turned into one direction. Then, the shaft 5 of a wheel 6, engaged with the bolt through a screw, is ascended along the bolt 13 while the transfer table 1 is moved downward since the position of the shaft 5 is not changed whereby the height of the mount rail 2 is lowered and coincides with the height of a running rail. Then, the nut 14 is tightened to fix it. On the contrary, when the mount rail 2 is lower, the bolt 13 is turned into reverse direction, then, the transfer table 1 is moved upward while descending the shaft 5 relatively along the bolt 13 whereby the height of the mount rail 2 ascends and coincides with the height of the running rail.

Title: Tape carrier package
Inventor: TERASAKA SHINJI
IPC: H05K3/36
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to reinforce the terminal parts of a tape carrier package without making large the size of the external shape of the terminals and to prevent the generation of a disconnection of the terminals due to vibrations by a method wherein when the terminals are provided on the peripheral edge parts of a base film in parallel to each other in a row shape, the width of the terminals, which are positioned on both end sides of the rows, is made wider than that of the terminals, which are positioned in the central parts of the rows. SOLUTION: When output terminals 5 are provided on the peripheral edge parts of a base film 1 in parallel to each other in a row shape, the width of the terminals 5, which are positioned on both end sides of the rows, is made wider than that of the terminals 5, which are positioned in the central parts of the rows. Moreover, panel terminals of the same width are installed on an LCD panel in the state corresponding to the terminals 5 of the different widths and the terminals 5 to correspond to the panel terminals and the panel terminals are connected with each other via an anisotropic conductive film. Accordingly, regardless of the positions of the rows, the distributions of stresses, which are respectively applied to each output terminal 5, become roughly uniform.  In such a way, as the widths of the terminals 5 are formed wider as the terminals 5 become more distant from the center parts of the rows to the outside, it is eliminated that a large force is applied to the specified terminals and a disconnection of the connection parts of the terminals 5 with the panel terminals hardly generates.

Abstract: PURPOSE: To discriminate the propriety of the craze of an egg by binarizing the dense and plate image obtained by photographing the state of a light passing an egg interior to obtain binary images of pixels of a streak pattern part and the crazed part, and expanding or contracting the pixels. CONSTITUTION: An image photographing unit 22 photographs the image formed by a light passing through an egg 110 irradiated by a light source 20 to obtain a gray level image.

Thus, a binary image in which the normal part of the egg 10 is assumed to be a fixed density B and the craze and the stream are assumed to be A is obtained. The different points of the shapes and distributions of the craze and the streak are emphasized by expanding. When the crazed area approaches the linear area by nicks or branched cluster together and expanded, the vicinity part is coupled and enlarged.  Contrary, the streak area is thickened by expanding, and when it is contracted, the stream is eliminated, and the craze is remained at the coupled part to be discriminated.
