Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal element having a memory characteristic and high contrast by specifying the selection reflection wavelength of the liquid crystals of the liquid crystal element having a pair of substrates and a composite film. SOLUTION: This liquid crystal element is formed by holding the composite film 3 between a pair of the transparent substrates 1a and 1b arranged to face each other and transparent conductive films 2a and 2b are formed on the inside surfaces of the substrates 1a, 1b. The composite film 3 exists between the conductive films 2a and 2b and is composed of a resin 3b having a network structure (matrix structure) and the liquid crystals 3a indicating a cholesteric phase. The liquid crystals 3a fill the meshes of the resin 3b. Chiral nematic liquid crystals, etc., formed by adding a chiral material to metatic liquid crystals, etc., are used for the liquid crystals 3a. The selection refection wavelength of the liquid crystals 3a is so selected as to attain 1.0 to 1.5μm.  As a result, the liquid crystal molecules appear transparent when the liquid crystal molecules attain a planar arrangement state. The liquid crystal molecules appear turbid when the liquid crystal molecules attain a focal conic arrangement state. A good contrast is thus obtd. between the transparent state and the scattered turbid state.

Title: Frequency separating type single tube color video camera
Inventor: ARISE FUSAYOSHI
IPC: H04N9/083
Filed: 1983-09-02
Abstract: PURPOSE:To improve the color reproducibility of a reproduced picture by controlling a gain of a variable gain amplifier circuit to which a modulated chrominance signal is fed depending on the degree of the aperture to compensate the reduction in the modulation of the modulated chrominance signal. CONSTITUTION:A luminance signal separated at a signal processing circuit 5 is fed to an aperture control circuit 13, a DC component of the luminance signal is separated to control the aperture 2. Since the level of the luminance signal is changed depending on the irradiated luminous amount of a photoelectric converting section 3, the irradiated luminous amount of the converting section 3 by the change in the opening of the aperture 2 is kept constant. The gain of a separation circuit 9 is increased when the level of the luminance signal at a low illuminance is low by the control signal formed from the detected luminance signal by the circuit 13. Thus, even if the modulation of a modulated red signal or a modulated blue signal is decreased at a low illuminance, the gain of the circuit 9 is increased to compensate the reduction in the modulation.

Title: Probe card
Inventor: FUJIWARA KAZUO
IPC: G01R1/073
Filed: 1991-07-01
Abstract: PURPOSE:To test the temperature of a semiconductor chip in a wide temperature range with a single probe card by forming a curved section in a probe and providing a thermal displacement member which changes the degree of curved state of the curved section depending upon the temperature. CONSTITUTION:A probe 3 is constituted in such a way that a curved section 3a is formed of, for example, tungsten on the inside of an insulating resin 4a and its tip 3b is brought into contact with an electrode pad 8 on a semiconductor chip 7. A metallic ring 5 fixed to an insulating resin 4c through the probe 3 and another insulating resin 4b is provided on the inside of the curved section 3a. When the chip 7 is heated from a stage 6, the chip thermally expands outward and the pad 8 is displaced to the outside. The ring 5 also thermally expands to the outside due to the heat radiated from the stage 6 and contracts the probe 3 so that the degree of curved state of the curved section 3a can become smaller. Therefore, the tip 3b also moves along with the displacement of the pad 8 and both can be surely brought into contact with each other. It is also possible to paint the surface of the ring 5 to black and, in addition, to add a heat absorbing plate.
