Title: Metallic structural member having impact absorption function
Inventor: KAWADA NARINORI
IPC: B23K20/12
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce weight and a cost of a metallic structural member having an impact absorption function without necessitating another impact absorption member by applying friction stirring treatment locally using a rotating probe to form an impact energy absorption part. SOLUTION: A basic member 10 is a pipelike extruded member having a square cross section and is made of aluminum alloy. A probe 31 of a treatment device 3 is inserted into the basic member 10 until it passes through a peripheral wall by rotating it. An end face 32 presses a surface of the basic member 10. A rotator 30 and the probe 31 are moved over whole periphery of the basic member 10 while maintaining an insertion condition of the probe 31. The basic member 10 is plasticized and softened in the vicinity of its contact part with the probe 31 due to friction heat caused by slide contact of the probe 31 and the basic member 10. Moreover, it loses friction heat rapidly and is cooled and solidified after receiving progressive pressure of the probe 31 and flowing plastically to embed a groove through which the probe 31 passes.  This phenomenon is sequentially repeated in accordance with the travel of the probe 31 to form a beltlike impact energy absorption part made of minute metallographic structure.

Title: Magnetic bubble storage element
Inventor: YOSHIOKA SHINYA
IPC: G11C11/14
Filed: 1982-11-22
Abstract: PURPOSE:To improve the accuracy of the optimum matching position as well as the production yield by providing plural sets of matching patterns to both a conductor pattern layer C and a ''Permalloy'' pattern layer P respectively and disposing the matching pattern shifting by a different degree from the center position of the matching pattern with the layers C and P for each set of both pattern layers. CONSTITUTION:It is supposed that the optimum matching position obtained from the evaluation of the integrated working characteristics of a finished element shifts by +0.2mum and -0.2mum in directions X and Y respectively to a designed center position. In such a case, a matching pattern G is used with the matching operation at a subsequent production. The pattern G is already shifted in the design stage to the directions X and Y by -0.2mum and +0.2mum respectively. As a result, the shift degree is substantially compensated by obtaining the coincidence between the center positions of matching patterns of both layers C and P. Thus the optimum matching is possible as desired. In such a way, it is possible to improve both accuracy of matching position and production yield for a magnetic bubble storage element.

Filed: 1990-08-01
Abstract: PURPOSE:To simplify the structure and assembly of a head cleaner by utilizing the operation of a slide plate for switching the posture of a supporting arm having a solution feeding body for applying a cleaning solution to a cleaning tape. CONSTITUTION:A solution applying means 17 supports the base end part of the supporting arm 20 having the solution feeding body 19 at its head side by a spindle 21 erected from a lower case 1b so as to optionally horizontally oscillate the base end part. When the slide plate 16 is moved to a rear opened direction at the time of using this head cleaner, the arm 20 is switched to solution feeding posture for allowing the body 19 to come into contact with the cleaning tape 3 and the cleaning solution infiltrated into the body 19 is applied to the tape 3. When the plate 16 is moved to a front closed position, the arm 20 is switched to stand-by posture for separating the body 19 from the tape 3. Since the arm posture switching operation is executed only by a turning mechanism having simple structure and requiring no return spring, the assembly of the head cleaner is simplified.

Title: Method and apparatus for measuring mixed fluid
Inventor: IZUMI YOSHIKAZU
IPC: G01R27/26
Filed: 1992-07-31
Abstract: PURPOSE:To measure the stability of emulsifying liquid and a dispersing system by using capacitance and to express the degree of the stability quantitatively by providing two pairs of electrodes at the two different positions of a container, wherein fluid to be detected is inputted, so that the fluid to be detected infiltrates between the electrodes. CONSTITUTION:Capacitors C1 and C2, which are counter electrodes respectively, are arranged at two positions where the dispersing states of liquid to be emulsified are different in a container 10. The oscillating frequencies of timers IC 1 and IC 2 are determined by the resistance values of resistors R1-R4 and the capacitances of the capacitors C1 and C2. The resistance values of the resistor R1 and me resistor R3 and the resistor R2 and the resistor R4 are equally set. When the capacitances of the capacitor C1 and C2 are equal, the timers IC 1 and 2 transmit the equal frequency. The capacitance ratio between the capacitors C1 and C2 is taken out as the transmitting frequency ratio of the timers IC 1 and IC 2. Therefore, the stability is expressed as the function based on the capacitance ratio between two capacitors C1 and C2.

Title: Image forming device
Inventor: FUKADA SATOSHI
IPC: G03G15/16
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of color slurring and the change of color due to the deviation of the relative position of a photoreceptor drum to an endless belt corresponding to the drum for every color by constituting the device so that the peripheral length of the endless belt may be the non-integral multiple of the circumference of the photoreceptor drum. SOLUTION: This device is constituted so that the peripheral length of the intermediate endless belt 4 may be the non-integral multiple of the circumference of the photoreceptor drum 1. A speed difference is set between the circumferential speed Vp of the drum 1 and the circumferential speed Vb of the belt 4. Assuming that the rate of the speed difference is ΔV(≠0), the relation of the speed is expressed by an expression Vb=Vp×(1+ΔV). By setting the rate of the speed difference ΔV in such a way, the relative positional relation of the drum 1 to the belt 4 is deviated by as much as the speed difference.  Therefore, the deviation is corrected and the relation among the circumference Lp of the drum 1, the peripheral length Lb of the belt 4 and the circumference Lr of a driving roll 5 is set to meet the expressions Lb=Lp×(1+ΔV)×n and Lr=Lb/m=Lp×(1+ΔV)×n/m so that the respective dot positions constituting an image may be synchronized.
