Title: Specific area extract device and its method, specific area information recorder and its method, and specific area information recording medium
Inventor: MIZUFUJI TARO
IPC: H04N5/91
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To extract accurately a specific area such as all telop signals under every environment. SOLUTION: A uniform recording area detection circuit 3 compares a luminance level of an optional picture element of a video signal in a television signal with a luminance level of surrounding picture elements to detect an area of a nearly uniform luminance level. A high frequency area detection circuit 4 detects a high frequency component in an optional video image plane of the video signal. A constant time no change picture element detection circuit 5 discriminates whether or not the luminance level of the optional picture element is unchanged for more than a prescribed time. An extract circuit 6 extracts a telop signal based on each output of the uniform recording area detection circuit 3, the high frequency area detection circuit 4 and the constant time no change picture element detection circuit 5.

Title: Spectral photometer
Inventor: SAKAYANAGI NOBUYUKI
IPC: G01J3/447
Filed: 1994-02-08
Abstract: PURPOSE:To eliminate the influence of polarization characteristics which an optical system itself has and to efficiently measure the transmission rate or reflection factor of a polarization sample by laying out a polarization element on a light path of light emitted from a spectroscope and then taking out linear polarization with a specified azimuth angle referring to the polarization axis of the polarization sample. CONSTITUTION:A spectroscope 12 consists of an optical element with the polarization characteristics of a dispersion element etc., generates a diversified polarization, and hence greatly affects the transmission rate of a polarization sample 18. To prevent it, a polarization element 14 is laid out on the light path of the spectroscope 12 and the polarization surface is inclined by 45 degrees from the polarization axis of the sample 18 and the light is applied to the sample 18. Many samples 18 are in square shape as in a liquid crystal panel and the square sample 18 has a polarization axis which is parallel to one opposing side and can be set so that the polarization axis can be in a fixed direction. Therefore, by laying out the polarization element 14 so that a linear polarization with an azimuth angle of 45 degrees can be obtained for the polarization axis of the sample (polarization plate) 18, the average value of transmission rate or reflection factor can be accurately and efficiently measured with a single measurement.

Title: Welding power source unit
Inventor: SHINADA TSUNEO
IPC: B23K9/067
Filed: 1979-03-28
Abstract: PURPOSE: To stabilize the output of the feedback system at the following no-load time by directing the output of an SCR gate signal control circuit to the offset level at the time constant larger than the level before no-load at the time when no-load output is emitted owing to the arc break-off of a short time.  
     CONSTITUTION: The welding voltage controlled by the output control element connected to a main transformer is fed back and compared with a reference voltage. And the welding power supply unit is so constituted that the feedback signal controlling the input of the output control element according to its differential voltage is changed over to the specified voltage when welding arc stops. Hence, even if the no-load voltage owing to arc break-off is generated in a short time, the output at the arc starting does not change with said high no-load voltage and therefore the arc start is stabilized. Even if the no-load voltage of a long time is generated at such a time as starting, the conditions at the starting may be made constant by adjusting the offser level of the feedback circuit and therefore, the rush at the starting and output defficiency may be prevented and stable welding performed.

Abstract: PURPOSE:To enlarge the allowance for tilting in the direction of the tracking or tangential direction and to reduce the amount of cross-talk as output characteristics by tilting the direction of a far-field pattern to the pit string of a disk. CONSTITUTION:The direction of the longer axis of a far-field pattern of a beam irradiated from a semiconductor laser is made to tilt to the bit string 1 on the disk, most desirably, made to be irradiated at an tilting angle of less than 45 deg.. Accordingly, the position at which the smallest beam diameter Wo is obtained for the pit string 1 on the disk is also in a face tilting by theta to the pit string 1. In this face, the beam diameter becomes small. However, the level of strength H2 in the outside zone becomes large. However, as the far-field pattern is tilted to the pit string 1, the distance to adjoining tracks 2, 3 can be made large. The distance becomes maximum when the angle of tilting is 45 deg. and interference with adjoining tracks 2, 3 can be made small.

IPC: H05B41/282
Filed: 1995-02-23
Abstract: PURPOSE: To provide a power supply in which the voltage can be boosted up to a desired level using a transformer having a low turn ratio when it is required to apply a high voltage to a load from a power supply of low voltage. CONSTITUTION: A pair of transistors Q1 , Q2 are connected in reverse parallel with diodes D1 , D2 , respectively, to form switching elements and the series circuit of both switching elements is connected across a capacitor C0 . Both transistors Q1 , Q2 are turned ON/OFF alternately at high frequency through a control circuit 8. The transistor Q2 on the low voltage side is connected through the primary winding of a transformer T1 with a DC power supply 1. With such circuitry, a capacitor C0 is applied, when the transistor Q2 is turned OFF, with the voltage of a power supply 1 added with the voltage induced in the primary winding of the transformer T1 by the energy stored therein when the transistor Q2 is turned ON.  Since the voltage across the capacitor C0 is utilized when the primary winding of the transformer T1 is conducting, a high step up ratio can be ensured even if the turn ratio of the transformer T1 is low.

Abstract: PURPOSE:To prevent the charge quantity from being controlled erroneously because of the detection of a joint, a slit part, or the like, by detecting a non- charged part of a photoreceptor accurately and holding the control state at this detection time. CONSTITUTION:When a photosensor 11 detects a hole 1b, a detection signal indicating that a joint 1a comes immediately after is outputted to a holding circuit 12. The circuit 12 holds a current analog controlling signal Vc for a prescribed time T (t3-t4) from this time. Consequently, since a power supply controlling circuit 9 is controlled by the held value, the power supply controlling circuit 9 is prevented from being controlled erroneously because of the reduction of a sensor signal V of a potential sensor 3 when the sensor signal V is lowered by the joint 1a (I).

Abstract: PURPOSE:To) ensure safety by providing a moving part control means at an operating section which is provided with a moving part operating means at an inserting part and at least one operation means formed other than it to set the moving part disabled when both the operation means are operated simul taneously. CONSTITUTION:A bending switch 10, an air/water feeding switch 8 and a suction switch 9 are arranged in an electronic endoscope 1 and linked to a motor control section 30.
