Patent JP-H0370283-A (JP)
Title: Magnetic recording and reproducing device
Inventor: NARITA YOSHIO
IPC: G11B5/027
Filed: 1989-08-09
Abstract: PURPOSE:To easily seek a required picture by adding an offset voltage to a crosstalk component of both adjacent tracks used for noise bar control so as to change the control position of the noise bar depending on the magnitude of the voltage. CONSTITUTION:A recording signal fetched by a head 1 is amplified by a preamplifier and a band pass filter 3 of a next stage extracts a pilot signal from the recording signal. The pilot signal is subtracted at subtraction circuits 4, 4' with a signal selected by an internal oscillator to be an adjacent crosstalk component. The crosstalk component is represented as a voltage by detection circuits 5, 5'. Then the crosstalk component of preceding and succeeding tracks is converted into a voltage and the position of fixed noise bar is decided depending on how much of the offset voltage outputted from an offset generating circuit 7 is added to the detection level of the preceding and succeeding tracks before the component is compared by a comparator circuit 6. Thus, the position of fixed noise bar is varied optionally to easily seek a required picture.

Title: Method for controlling water-content of grain
Inventor: HINO MASAMICHI
IPC: A23B9/00
Filed: 1984-09-29
Abstract: PURPOSE:To obtain packaged grain having desired water-content, in high efficiency, by dividing grain into plural groups by water-content, discharging the grain from two or more groups in a manner to attain the ultimate target water- content, and sealing the grain mixture. CONSTITUTION:For example, rice is adjusted usually to a water-content of 14.5%, bagged, and stored in sealed state. The rice A having uncontrolled water- content is adjusted to a water-content of about 14-15% in the water-content controlling zone 10, and divided into 3 groups by water-content using the water- content selector 11. The first group I (water-content: 14.5%), the second group II (water-content: 14%) and the third group III (water-content: 15%) are stored in the hoppers 12, 13 and 14, respectively. The rice in the hopper 12 is packaged as it is in the bag 18 by the first packing apparatus 15, and the rice in the hopper 13 is mixed with the rice in the hopper 14 by the second packing apparatus in a manner to attain the average water-content of 14.5%, and packaged in the bag 22.

Title: Vortex flaw detection method of pipe and bar material
Inventor: TAKAISHI KAZUHIDE
IPC: G01N27/90
Filed: 1988-08-19
Abstract: PURPOSE:To detect a facial flaw with detection sensitivity close to that for a flaw along an axial direction of a pipe and bar material even if said facial flaw is a slanted short flaw by a method wherein a coil diameter of a detection coil is determined by the length of a facial flaw so that substantially non- directional detection sensitivity is provided. CONSTITUTION:A coil diameter of a detection coil is specified to a size with which the sensitivity characteristics of the detection coil is close to substantially non-directional characteristics with respect to the average length of a facial flaw. By determining the coil diameter of the detection coil with the flaw length considered, a facial slanted flaw on the surface of a material to be inspected can be detected with detection sensitivity close to that for flaws along the axial direction of a pipe and bar material with high reliability even though the facial flaw is a short slanted one.

Title: Image forming device and control method for the same
Inventor: ENDO SHUICHI
IPC: G03G21/14
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To obtain an image of high quality for a long term by preventing toner which is charged with a polarity opposite to that generated on a photoreceptor from being shifted to a transfer roller, and securing the life of the transfer roller. SOLUTION: As for the control method, a voltage to be applied on a developing roller is switched from a positive voltage to a negative voltage at a time T2 when the leading end of the electrostatically charged area of the photoreceptor reaches a developing part where a developing roller comes into contact with the photoreceptor. Similarly, at a time T3 when the leading end of the electrostatically charged area of the photoreceptor reaches a transfer part where the transfer roller comes into contact with the photoreceptor, a positive voltage is applied on the transfer roller in place of a GND applied until that time. And an operation of writing an image pattern on the photoreceptor is started by an exposure device at a time T4, and developing is executed in accordance with the image pattern from a time T5 when the leading end of the exposure area reaches the developing part.  Besides, a paper feeder is controlled so that the leading end of the transfer paper may reach the transfer part at a time T6 slightly earlier than the time T7 when the leading end reaches the transfer part.

Title: Television display device
Inventor: IWAMA JUN
IPC: H04N9/00
Filed: 1988-08-18
Abstract: PURPOSE:To eliminate dislocation for the display position of a character on a screen by forming a clock signal to set the display position based on an index signal from a color cathode ray tube when the character is displayed. CONSTITUTION:When the character is displayed in a part of the screen, the clock signal to set the display position is formed from an index signal SI which comes from an index system color cathode ray tube 1. Accordingly, when character display is designated, the character is displayed to the determined position on the screen of the cathode ray tube 1. In such a case, since the character display position is determined with the count value output of address counters 12 and 13 as reference and the address counter 12 counts the index signal SI as a clock, the position of the display character is not dislocated in a horizontal direction. Thus, the display position of the character is prevented from being dislocated according to a temperature characteristic or dispersion, etc., in the output of a clock oscillator.

Title: Fault location detector for optical fiber line
Inventor: HORIUCHI YUKIO
IPC: H04B17/00
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To improve detection accuracy of a faulty point. SOLUTION: Optical fiber gratings 10a which reflect a wavelength λ1 different from a signal wavelength λs are placed to proper positions on an optical fiber line 10 at a proper interval. The signal light with the wavelength λs is sent through the optical fiber line 10 without being reflected by the gratings 10a. An optical pulse test device 14 outputs a probe pulse light with wavelength bands λ0, λ1 different from the signal wavelength λs in different times. The probe light with the wavelength bands λ0, λ1 is given to the optical fiber line 10 via an optical multiplexer/demultiplexer 16 and propagated through the optical fiber line 10. The reflected probe light with the wavelength λ1 includes the reflected pulse by the gratings 10 and the reflected pulse is used for a position reference.  The probe light with the wavelength λ0 does not include the reflected pulse by the gratings 10a. The optical pulse test device 14 compares the reflected light with the wavelength bands λ0, λ1 with each other to detect the presence of a fault and its position with high accuracy.

Title: Sliding member
Inventor: TANDA HIROKO
IPC: F16C33/20
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a sliding member with wear and heat resistant characteristics under high speed and high load conditions in a non-lubrication state by forming the member out of a resin composite body composed of thermoplastic resin and fiberous filler, and setting the average diameter and dominating area ratio in specified ranges. SOLUTION: This sliding member comprises a resin composite body of thermoplastic resin and fiberous filler, wherein the content of fiberous filler is set in a range of 70-30 volume % while that of fiberous filler in a range of 7-30 volume %. If the content of resin is above 70 volume %, change at the thermosetting time becomes large, and thereby no high shape retaining characteristic is obtained. If it is below 30 volume %, on the other hand, the shape retaining after the powder compression formation is hard. The average diameter of air holes existing in the sliding surface is made 15-80 μm. Accordingly, the contact area with a mating member can be reduced for improving the heat radiation therein and remarkably reducing wear on the sliding surface.
