Title: Current detector
Inventor: NODA MINORU
IPC: G01R15/20
Filed: 1986-11-10
Abstract: PURPOSE:To form a large magnetic field by a small current and to faithfully detect a small current to be measured, by arranging a magnetism-sensitive element in the vicinity of the outside of the magnetic gap of a ferromagnetic core. CONSTITUTION:A current to be measured is supplied to a coil 13 from an external input/output terminal 21 through a lead wire 18 and the magnetic field corresponding to the current to be measured is generated not only in the magnetic gap provided to the magnetic path of a ferromagnetic core 11 having an annular shape but also in the vicinity of the outside of said magnetic gap. The resistance of a pattern crossing the upper surface direction of the ferromagnetic core of a magnetic resistor element 15 at a right angle changes corresponding to the leaked magnetic flux from the magnetic gap. This resistance change is guided to a signal processing circuit containing a circuit mounting board 20 and an adjusting part 25 as a voltage signal. Then, the signal amplified is taken out to the outside through the terminal 21.

Title: Method of detecting length of electrode for arc furnace
Inventor: EZAKI TATSUYA
IPC: F27B3/28
Filed: 1992-10-05
Abstract: PURPOSE:To detect the length of an electrode with a high accuracy during the operation of an arc furnace. CONSTITUTION:The length L3 of an electrode below a clamp 4 is measured immediately after elongating the electrode 3 initially to obtain a reference length. During the operation, a clamp height signal or a PLG value is detected at the time point of the heat increasing step 1 of respective chargings. The consumed length of the electrode is obtained by a difference between the PLG values of respective chargings and the PLG value of the first charging while the length L3 of the electrode below the clamp 4 during the operation is obtained by subtracting the consumed length of electrode from the reference length.

Title: Pick moving method of disk type recording and reproducing device
Inventor: SUGIMOTO HIROSHI
IPC: G11B7/085
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To speedingly conduct the pick movement of the device. SOLUTION: Three steps are required to access a target position from a present position. First, the number of tracks to be jumped from the present address to a target address is obtained from table data and the pick makes a large movement. Note, however, that if the computed number of jump tracks exceeds 500, no coarse movement takes place and it proceeds to a next step (Step 1). Then, having completed a movement, a present address is detected and an accurate computation is made to compute the number of tracks to be jumped and the pick is moved accordingly (Step 2). Finally, the pick tracks the disk data until the present address matches with the target address and puts itself into a standby condition (Step 3).

Title: Picture input device
Inventor: KAMIHIRA KAZUTAKE
IPC: G06T5/00
Filed: 1989-10-16
Abstract: PURPOSE:To take gradient suitable for the visual property of human eyes by providing a signal correcting means to set a relationship between brightness I of an object and a extent Va of an analog signal before A/D conversion so that a fine coefficient dVa/dI of the Va concerning the I can be decreased accord ing as the I is enlarged. CONSTITUTION:A figure shows a relationship between the transmissive light intensity of a photochromic thin film 1 formed on an image sensor and incident light intensity. The relationship between the transmissive light intensity and the incident light intensity is made non-linear by a character for the material of the photochromic thin film 1 and applied by a curve which is projected upward. In a photodiode 3 of a CCD area sensor, a current in proportion to the incident light intensity is generated by photoelectric conversion. However, since the photochromic thin film 1 with a property shown in the figure is arranged on the CCD area sensor and light transmitted through this material is made incident to the photodiode 3, the relationship between the brightness of the object and the output voltage (or the current) of the photodiode 3 is made similar to a property shown by a real line in the other figure. Thus, a gradient method can be realized suitably for the visual property.

Title: Magnetron sputtering device
Inventor: MATSUMURA FUMIO
IPC: H01L21/285
Filed: 1984-12-19
Abstract: PURPOSE:To maintain the specified shape in the eroded part of a target surface and to make uniform the thick film distribution by disposing an annular permanent magnet behind the target and providing means for supporting the permanent magnet in an eccentric position and turning and moving the magnet. CONSTITUTION:The annular permanent magnet 20 is attached to a movable shaft 21 and is disposed behind the target 4. The shaft 21 supports the magnet 20 in the eccentric position thereof. The part to be eroded most strongly on the surface 4a of the target 4 moves continuously when sputtering is executed while the magnet 20 is rotated. The target surface 4a is thus eroded to a smooth U shape and the utilizing efficiency of the target 4 is improved. The shaft 21 is moved in an axial line direction to adjust the distance between the surface in the eroded part of the target 4 and the magnet 20 to always maintain the specified magnetic flux density on the target surface 4a. The change of the film thickness distribution with lapse of time is decreased by such device.

Title: Motor drive
Inventor: KOBAYASHI TOSHIHARU
IPC: H02P7/288
Filed: 1988-10-22
Abstract: PURPOSE:To correct a voltage offset section automatically by correcting the voltage offset of a DC motor on the basis of the value of a voltage applied to the DC motor and the value of a current flowing through the DC motor. CONSTITUTION:A digital output signal from a signal processor 1 is changed into an analog signal by a D/A converter 2, and applied to the bases of transistors 4, 5 through an amplifier 3, thus changing the resistance of the transistors 4, 5, then altering an applied voltage value to a DC motor M. The value of a current flow through the DC motor M is converted into a digital value by an A/D converter 6, and transmitted to the signal processor 1. The signal processor 1 computes applied voltage (offset voltage) bringing currents flowing through the motor M to zero on the basis of the ratio of motor applied voltage to the increment of currents, and corrects an offset section on the basis of the offset voltage.

Filed: 1985-11-26
Abstract: PURPOSE:To suppress the wear of a guide mechanism and to prevent the generation of dust by using a porous member impregnated with a lubricant to produce at least a rail or the outer ring of a bearing. CONSTITUTION:A bearing outer ring 11 is made of a metal and a rail 12 is made of ceramics. The film 14 of a lubricant is impregnated into may holes 13 of the rail 12.

Title: Method for detecting broadcast station and television receiver utilizing the same
Inventor: OZAKI SATORU
IPC: H04N5/44
Filed: 1993-10-26
Abstract: PURPOSE:To considerably shorten automatic search time by controlling the tuning frequency of a tuner so that all the first frequency ranges of respective television systems can be included in a second frequency range. CONSTITUTION:When selecting any channels excepting for channels 5 and 6, a certain fixed frequency (around -1MHz) lower than a standard frequency is tuned (c) so that an offset frequency range (a) of a carrier wave frequency can be included in the frequency range to detect a time base signal. Therefore, it can be decided whether the broadcast signal of that channel is present or not by checking whether the time base signal is present or not in the state of tuning the standard frequency -1MHz. As for the channels 5 and 6, it is enough just to tune a certain fixed frequency (around +4MHz) higher than the standard frequency. Thus, the presence/absence of the broadcast station can be decided just corresponding to the presence/absence of the time base signal without searching the tuning point of a signal using an AFT signal.
