Abstract: PURPOSE:To suppress enough a Barkhausen noise by varying a bias magnetic field at a sufficiently higher speed than a moving speed of a magnetic wall, and suppressing a non-reversible movement of the magnetic wall in a magneto- resistance effect element. CONSTITUTION:A bias conductor 3 is provided on the vicinity of an MR element 1 through an insulator 2, a high frequency bias current Ib flows through a lead wire 6d, a connecting terminal 4b, the bias conductor 3, a connecting terminal 4a, and a lead wire 6a, and a bias magnetic field of the MR element 1 is generated in the bias conductor 3. A resistance value of the MR element is varied in accordance with these magnetic fields, a reproducing signal varied in accordance with said variation is supplied to a pre-amplifier, amplified thereby, and thereafter, rectified and detected by a detecting and rectifying circuit 10, and a desired information signal is obtained in an output terminal. The high frequency bias current Ib flowing to the bias conductor 3 is a current which is varied alternately to a high speed, and its rise and fall are set steeply. This frequency is made higher enough than a response speed of a magnetic wall of the MR element 1, and when it is >=100kHz, a non-reversible movement of the magnetic domain is suppressed.

Title: Seal device for drilling direction control part of drilling machine
Inventor: IKEDA AKIO
IPC: E21B7/08
Filed: 1995-03-28
Abstract: PURPOSE: To improve sealing property by providing a pressure equalizing mechanism between muddy water and lubricating oil on a shaft of the upper part of a universal joint, and connecting a seal box provided on a lower shaft to a housing through a bellows. CONSTITUTION: When lubricating oil 44 enclosed in a cylindrical housing 6 is expanded by high temperature at a bottom hole so as to become higher pressure than muddy water 45, the lubricating oil flows from a communicating hole 43 into a bladder 41. Next, the bladder 41 is expanded outward, and the expansion is stopped when the pressure is equalized. Next, when the muddy water 45 becomes higher pressure than the lubricating oil 44, the lubricating oil 44 flows out of the bladder 41 through the hole 43, and the contraction of the bladder 41 is stopped when the pressure is equalized to that of the muddy water 45.  Further, when a lower rotary shaft 2 is bent against the housing 6, in a lower seal device 7, a seal box 21 and a mechanical seal 23 are made eccentric against the housing 6, but a bellows 26 is deformed so as to absorb the eccentric quantity, and hence the function of the mechanical seal 23 is ensured. Hereby, leakage of lubricating oil and invasion of muddy water can be prevented.

Abstract: PURPOSE: To provide a cold trap which prevents restriction due to difference between the axial  thermal expansion of inner and outer walls of an insulating gas layer, by forming an annulus structure of insulating gas layer, which caused no restriction to the outer and inner walls, between a  cooling section and an impurity collecting section.   
     CONSTITUTION: A cold trap has a cooling section 11 installed side by side with an impurity collecting section 7, both the sections being separated within a liq. An outer wall 4 of a thermally insulating gas layer is installed along the inner wall 5 of the thermally insulating gas layer, an outlet  nozzle 2 being used simultaneously for the upper parts of both the walls, and the upper end of the  outer wall 4 is opened to the gas layer of the cold trap. The distance of the upper end of the outer  wall 4 from the upper end surface 15 of the cold trap is made larger than the maximum difference  between the thermal expansions of the inner and outer walls 4, 5 which is developed during the  service life of the cold trap. Spacers 14 are attached between the inner wall 5 and the outer wall 4  to prevent the decrease in thickness of the thermally insulating gas layer 12 due to external force.  The lower end of the gas layer is sealed by welding. A plate 13, which prevents liq. from flowing  in, is attached around the upper end of the outer wall 4 in order to prevent the fluid formed by  condensation at the upper end plate 15 from flowing into the gas layer 12.

Title: Arithmetic system for mean value
Inventor: SAKO KAZUYA
IPC: E05F15/10
Filed: 1983-05-31
Abstract: PURPOSE:To decrease the number of memory areas and at the same time to shorten the arithmetic processing time by obtaining the total sum or the mean value of (n) units of latest data from the preceding arithmetic value stored in a memory and storing it to said memory. CONSTITUTION:The total sum or the mean value of (n) units of data is obtained and stored once in an RAM4. Then the preceding mean value is subtracted from the preceding total sum every time the new data is supplied to a microprocessor unit MPU. The new total sum is obtained by adding the new data to the result of said subtraction, and then the new mean value is obtained from the new total sum. These new total sum and mean value are replaced with the preceding total sum and mean value stored in the RAM4. The mean value is compared with the threshold value for example. Then the generation of a fault is decided if the mean value is larger than the threshold value. This is utilized to give the reverse revolutions to the motor of the power window of a car.

Title: Chinese character converting device
Inventor: TAKITA YOSHIO
IPC: G06F17/22
Filed: 1993-04-22
Abstract: PURPOSE:To obtain the KANJI(Chinese character) converting device which performs KANJI conversion with good selection efficiency by utilizing conversion dictionary information on words in a sentence containing a word as an object of homonym selection and conversion dictionary information on other words at the head of the sentence which are already converted. CONSTITUTION:An input character string is inputted through an input means 1 and a converting means 2 takes a morpheme analysis and a syntax analysis of the input character string to convert the input character string into the notation of words corresponding to the input character string. When there is a homonym, a 1st homonym selecting means 3 selects the homonym. Further, when the 1st homonym selecting means 3 can not select it uniquely, a concept information takeout means 5 takes concept information out of a determined sentence memory 4. Then the idiom is selected by a 2nd homonym selecting means 6 by using converted concept information and the taken-out concept information and the selection result is outputted by an output means 7.

Title: Magnetic recording medium
Inventor: MIZUSHIMA KOUICHI
IPC: G11B5/64
Filed: 1984-05-16
Abstract: PURPOSE:To improve the recording density by irradiating an energy beam to laminated films formed by laminating plural kinds of non-magnetic films which are raw materials for spinel ferrite on a substrate thereby forming a ferromagnetic ferrite pattern. CONSTITUTION:Many layers of thin films consisting of hematite 2 and one or plural materials among Ni oxide 3, copper oxide, Mn oxide, Zn oxide and Mg oxide which are raw materials for spinel type ferrite are laminated on the substrate 1 to form the laminated films thereon. When energy is then applied to the optional part of the laminated films by a light beam, ion beam, etc., the laminated films in the irradiated part are changed by a chemical reaction into the ferromagnetic spinel type ferrite. The recording of signals to the laminated films is made possible by such method. There is no need for writing the signals by a magnetic head if such recording method is used and therefore the material which exhibits large coercive force to overcome the diamagnetic field is usable as a magnetic material and the higher density recording is made possible.

Filed: 1979-07-27
Abstract: PURPOSE: To make it possible to replace and fix parts while paying attention to drive conditions of every car by detecting a car running on a rough road and then by integrating and recording the distance and time of rough-road drive when the detection signal reaches a certain value.  
     CONSTITUTION: Acceleration sensor 1 detects acceleration in drive on a rough road and its detection signal, after being amplified by amplifier 2, is output to deciding circuit 4 by way of differentiating circuit 3. Deciding circuit 4 decides on whether the acceleration exceeds its set reference value or not and then outputs the decision signal to integrating circuit 5. Switch circuit 6, when a signal from integrating circuit 5 shows that the acceleration exceeds the set reference value, turns on to send the signal to counter 7. With switch circuit 6 in the on state, rotary detecting sensor 8 sends a signal as to a drive distance obtained through the rotation of the driving shaft to counter 7. Counter 7 integrates and records the drive distance. Thus, parts that correspond to drive conditions can be replaced and fixed.
