Patent JP-H0346407-A (JP)
Title: Variable gain amplifier
Inventor: DEGUCHI TAKUMI
IPC: H03G3/10
Filed: 1989-07-14
Abstract: PURPOSE:To obtain a variable gain amplifier whose output phase is not inverted by providing a voltage limit circuit to a 3rd transistor(TR) pair which synthesizes outputs of 1st and 2nd TR pairs different in gain and controls the DC current to control the gain. CONSTITUTION:First and second TR pairs 9, 20 and 21, 22 are different in gain and collector signals in inverted relation are synthesized and outputted. Common base amplifiers 25, 26 are used as loads to the said TR pairs to improve the frequency characteristic. Moreover, 3rd TR pairs 23, 24 with a voltage control circuit limiting a DC current and a constant current source 9 are provided as the constant current source of the said TRs. Since one base potential is not lower than the other base potential with diodes 27, 28 of the voltage limit circuit, the gain control voltage is limited. Thus, the inversion of the output phase is prevented.

Title: Method for testing semiconductor device
Inventor: TSUGE NORIHISA
IPC: G01R31/30
Filed: 1989-07-14
Abstract: PURPOSE:To test the margin of the potential of a board by suspending a board- voltage generating circuit, and operating a semiconductor circuit wich is formed on the semiconductor board under the state wherein the board potential is forcibly changed with an external power source. CONSTITUTION:A transistor (Tr) Q14 is turned ON since the gate is pulled up to a power source Vcc with an impedance element R. The H and L outputs of an oscillator 10 turn ON and OFF a Tr Q13. The inverted signal of the oscillator 10 is generated at an output end N2. The signal is applied to the gate of a Tr Q8 of a pumping circuit 14 and also applied to a Tr Q2 of an inverter 12. The inverted output of the inverter 12 is applied to the gate of a Tr Q7 of the pumping circuit 14. Therefore, the Trs Q7 and Q8 repeat ON and OFF conversely to each other, and pumping operation is performed. In testing, a grounded probe is brought into contact with a terminal PD so as to turn OFF the transistor Q14, and the pumping circuit 14 is brought into a stopped state. In this way, the presence or absence of the abnormality in margin can be checked.

Title: Display element
Inventor: KOBAYASHI HIDEKAZU
IPC: C09K19/60
Filed: 1993-07-23
Abstract: PURPOSE:To provide a display element which is bright to meet applications by imparting directivity to the scattering of the display element formed by orienting and dispersing liquid crystals and high polymers with each other. CONSTITUTION:The orientation direction of the liquid crystals 3 and the high polymers 5 are twisted from 0 deg. to 180 deg. and further, to 270 deg., 360 deg. or above in a direction where an electric field is impressed. The conditions for constitution capable of taking advantage of the characteristics of the display element having such directivity to the max. possible extent are exhibited. As a result, the display element having the scattering characteristics meeting the applications is easily produced. For example, the bright display is realized by restricting the visual angle if the 0 deg. or 180 deg. twist is used in the case of use of the constitution liable to darken the display, like a color filter or touch panel. The use of the >=270 deg. twist suffices to make the display visible as white as paper when viewed from any direction.
