Title: Optical recording and reproducing device
Inventor: TOMITA HIROTOSHI
IPC: G11B7/09
Filed: 1988-01-27
Abstract: PURPOSE:To stabilize a displacement frequency characteristic in a focusing direction by providing a magnet which generates a magnetic field for driving symmetrically with respect to the center of gravity of a lens holder, and preventing a moment from being generated. CONSTITUTION:An objective lens 1 is supported by the lens holder 2, and forms a micro light spot on a recording medium. The holder 2 is mounted on an optical block 5 via a flat spring 3a. And the lens 1 performs parallel movement by a focusing coil 4 and a driving force generated by magnets 10a and 10b for the coil, and moves in the focusing direction F. Also, the lens 1 moves in a tracking direction T by the driving force generated by tracking coils 6a and 6b and magnets 8a and 8b for the coils via a block 5. At this time, the magnets 10a, 10b, and 8a, 8b are formed in columnar magnets, and whose longitudinal directions are arranged in parallel with a radius direction, and are arranged fixedly symmetrically with respect to the center of gravity of the holder by sandwiching the holder 2. In such a way, it is possible to prevent the moment from being generated around the center of gravity, and a stable displacement frequency characteristic in the focusing direction can be obtained.

Title: Device for detecting position of hot lump
Inventor: KURI TOSHIBUMI
IPC: G01B11/00
Filed: 1994-02-10
Abstract: PURPOSE:To prevent erroneous detection of a hot lump on a rolling processing line. CONSTITUTION:When a hot lump passes through a first point, a passing hot lump detecting means 1 outputs a detecting signal and a switching means 2 is turned on. As a result, the digital signal pattern outputted from an image picking-up means 3 provided at a second point at the same point of time is stored in a storing means 4 which stores digital signal patterns at the time when the hot lump passes through the first point. A pattern synthesizing means 5 generates synthesized signal patterns by subtracting the stored digital signal pattern from digital signal patterns succeedingly sent from the image 3. Therefore, even when a pattern part caused by other object than the hot lump which is an object to be detected is contained in the digital signal patterns sent from the means 3, the pattern part can be eliminated from the synthesized signal patterns. Since a hot lump position computing means 6 computes the position of the hot lump by using the synthesized signal patterns, erroneous detection can be prevented.

Abstract: PURPOSE:To eliminate the formation of an opening to a gas supply pipe and to substantially dispense with attachment parts, by securing one end of a tongue piece to the predetermined position in the gas supply pipe to vibrate the same in correspondence to the flow rate of gas and detecting said flow rate through the detection of vibration. CONSTITUTION:A tongue piece 2 is attached to the inner surface of a gas supply pipe 1 and a vibration detection means 3, for example, a condenser microphone is attached to the outer surface of said gas supply pipe 1 corresponding to the part, where said tongue piece 2 is attached, in order to detect the vibration of said tongue piece 2. The tongue piece 2 is formed of a thin plate comprising a material receiving no corrosion by gas and attached to the gas supply pipe 1 so as to be inclined at a predetermined angle toward the flow direction X of the gas. Because the vibration frequency of the tongue piece 2 and the flow rate of the gas have relative relation, by detecting the vibration frequency of the tongue piece 2 vibrated corresponding to the flow rate of gas, the flow rate of the gas can be detected.

Title: Inter-panel/mask distance measuring equipment for color cathode-ray tube
Inventor: MINAMOTO TAISUKE
IPC: G01B17/00
Filed: 1982-02-08
Abstract: PURPOSE:To quickly and accurately measure the distance between the thickness of a panel and the distance between the inner surface position of this face and a reference level using a detector consisting of a ultrasonic thickness meter probe, a linear scale, or the like and also measuring the inner surface position of a shadow mask and the distance between this inner surface position and the said reference level using a detector consisting of an eddy current type non- contact displacement meter probe, a linear scale, or the like. CONSTITUTION:When a probe driving control motor 4 is activated, a ball screw 5 is rotated and a lower measuring head 6 and an eddy current type non-contact displacement meter probe 8 mounted on its top is raised. Since the probe 8 slowly increases the output as its top approaches to a shadow mask M, the control motor 4 is stopped when the output reaches the preset value before the probe 8 is made to touch the mask M. Then the distance between a reference level 9 and the lower measuring head 6 at this time is detected by a linear scale 12 and the value is input to a computer.

Title: Generator for focus control signal of luminous flux
Inventor: TAKAGI AKIRA
IPC: G11B7/09
Filed: 1984-02-02
Abstract: PURPOSE:To form a focus servo system which is free from variation of its characteristics even though a detector has the incident light wheh no information recording surface exists, by detecting the shift of focus on the information recording surface with the same level of sensitivity regardless of the change of incident light quantity to the detector. CONSTITUTION:An adder 15 adds the pin diode outputs P1 and P3 and the DC voltage V1 of opposite polarity to the pin diode output obtained when no information recording surface. While an adder 16 adds the pin diode outputs P2 and P4 and the DC voltage V2 of opposite polarity to the pin diode output obtained when no information recording surface exists. Amplifiers 17 and 18 have the same amplification factor A. The output of a subtractor 19, i.e., the focus control signal S is shown as S=DELTAP=AKP{k1(x)+k3(x)-k2(x)-k4(x)}. A subtractor 20 controls the factor A of amplifiers 17 and 18 so that the sum of outputs of amplifiers 17 and 18 obtained by an adder 21 and the AKP are set at the fixed value V3. Therefore the AKP is constant although the total light quantity KP is changed due to the variation of reflection factor on the information recording surface. Thus the signal S is constant.

Title: High breakdown strength mos transistor and manufacture thereof
Inventor: INAMI NOBUO
IPC: H01L29/78
Filed: 1990-01-30
Abstract: PURPOSE:To improve breakdown strength and drive a large current by forming an oxide film on a low concentration drain layer and a high concentration drain layer, whose film thickness dereases the electric field intensity of the drain part, and makes the low concentration drain layer generate intensive inversion under an applied voltage. CONSTITUTION:An isolation oxide film 2, an oxide film 3, and a silicon nitride film 4 are formed on a P-type substrate 1, and the film 4 except the part on a channel region is etched and eliminated. A low concentration drain layer 5 and a high concentration drain layer 6 are formed by self-alignment ion implantation using a pattern of the film 4 as a mask. An oxide film 8 is formed on the layers 5 and 6 so as to have a thickness to decrease the electric field intensity of the drain part and make the layer 5 generate intensive inversion. Hence high breakdown strength structure and superior driving capability can be realized by selecting the thickness of the film 8, so that an MOS transistor having high breakdown strength and capable of driving a larger current can easily be obtained.
