Title: Automatic focus adjusting device
Inventor: MASUNAGA MAKOTO
IPC: G03B13/36
Filed: 1981-07-22
Abstract: PURPOSE:To simplify a circuit constitution and to improve noise resistance and to reduce a cost, by using a pyroelectric effect element sensing a change of infrared light as a light receiving element. CONSTITUTION:When an infrared light emitting diode 2 switched on and off for projecting modulated light is made scanned in an arrow direction A at the back side of a light projecting lens 4 towards an object to be measured for a distance, the intensity change of the infrared radiation received on a light receiving element 100 at each scanning position in accordance with the distance to the object to be measured varies. As a result, for instance when an infrared light is made incident in the form that the intensity of the infrared light on the element 100 becomes the largest on the way of scanning by the diode 2, an output of the element 100 i.e. a differential output of the infrared light intensity is generated. By using such a pyroelectric effect element sensing a change of infrared light as the element 100, a circuit constitution is simplified and the noise resistance is improved and a cost is reduced.

Title: Noise preventing circuit
Inventor: MIZUNO TAKAO
IPC: H04N5/213
Filed: 1980-08-20
Abstract: PURPOSE:To prevent noise with a simple circuit, by cutting off a synchronizing separation trnasistor (TR) and an AGC TR through noise component detected at a noise detection TR in a TV receiver. CONSTITUTION:When a pulsive noise having greater level than the synchronizing signal included in a video signal appears at an output terminal of the 1st video TR1 and at a terminal A being the input terminal of the AGC TR2, a noise detection TR5 turns on and about +B voltage sppears at the collector of a DC amplification TR7. A switching diode 8 between the terminal A and a synchronism separation TR4 is cut off to prevent the pulsive noise from being applied to the base of the TR4, and the TR4 is reverse-biased to prevent the noise signal from being appeared at a synchronizing output terminal 21. Simultaneously, although the voltage at the terminal A is also applied to the base of the 2nd video amplification TR3, the noise appeared on the screen is made unremarkable through a level set resistor 16.

Title: Information reproduction control method for optical magnetic information recording medium
Inventor: SUGIYAMA HISATAKA
IPC: G11B11/105
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To shorten a scanning direction diameter so as to improve apparent resolution by reducing a Kerr rotational angle by head produced by light spot irradiation and making a reproducing signal to respond to a part formed by eliminating a response limit region from an irradiation part in order to form the response limit region. SOLUTION: The strength and scanning speed of a light spot 102 are set in a magneto-optical disk having a plurality of marks magnetized on a recording surface, and this spot is irradiated with a light. Because of the irradiation, a temperature distribution protruded in the center is formed inside the light spot 102. A Kerr rotational angle is reduced by heat produced thereby, and a response limit region 101 is formed. Thus, after a recording layer 105 is cooled to a room temperature after scanning of the light spot, the magnetization of the recording layer 105 is recovered to a state before the scanning and the shape of a mark 104 is read.  Thus, since a reproducing signal reflects the response of a part formed by eliminating the response limit region 101 from the irradiation part of the light spot 102, the scanning direction diameter of the light spot 102 is shortened to the diameter of an effective spot 103 and seeming resolution is improved.

Title: Guest-host type liquid crystal display element
Inventor: YAMAMOTO KAZUKO
IPC: G02F1/137
Filed: 1987-05-12
Abstract: PURPOSE:To prepare a guest-host type liq. crystal display element which brings about no catalytic fading and has excellent light fastness, by dissolving a particular anthraquinone dye when at least two kinds of dichroic dyes are dissolved in a liq. crystal. CONSTITUTION:A guest-host type liq. crystal compsn. prepd. by dissolving an anthraquinone dye of formula I (wherein X is a benzene ring, S, or O; R1 and R2 are each alkyl or alkoxy) (e.g., anthraquinone blue dyes of formulae II and III) when at least two kinds of dichroic dyes are dissolved in a liq. crystal. When only one kind of the dye is used, only limited colors can be expressed. Therefore, liq. crystals having various hues have been prepared by using at least two kinds of dyes in the form of a mixture. However, the combined use of at least two kinds of dyes brought about a lowering in the light fastness of the dyes. This caused the dyes to be deteriorated upon exposure to light, so that not only the absorbency was lowered but also the color tone was changed. The use of the aforesaid dyes enables the preparation of a guest-host type liq. crystal display element exhibiting no catalytic fading and having excellent light fastness.
