Inventor: YANO YASUSHI
IPC: G03G9/083
Filed: 1984-07-31
Abstract: PURPOSE:To develop an electrostatic latent image low in potential to obtain a toner image high in density and image quality by using a magnetic carrier of spherical sintered ferrite particles having roughness due to primary particles on the surface, a specified median diameter, a specified apparent density, and a specified electric resistance. CONSTITUTION:The developer is composed of an electrically conductive toner and the magnetic carrier of the spherical sintered ferrite particles having roughness due to primary particles on the surface, and having a median diameter of 30-50mum, an apparent density of <=2.6g/cc, and a resistance of 6-72X10<4>OMEGA measured in the form of a magnetic brush. Since such a ferrite carrier is small in specific gravity and small in saturated magnetic flux density, the magnetic brush is soft, and a torque necessary for rotating magnets inside a sleeve, the electric characteristics of the magnetic brush can be stabilized for a long term, and an amt. of spent toner to be produced can be reduced. The use of the spherical sintered particles having roughness due to the primary particles on the ferrite surface can prevent brush marks perfectly.

Title: Jointing and brazing method
Inventor: ISHIMARU ICHIRO
IPC: G01N21/71
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To always feed a proper amount of brazing filler member to a jointing part by calculating a feature volume for the area based on an image signal received/converted from a specular reflected light in the jointing member melting area, and by stopping the feed of the jointing member and evacuating the member when the feature volume reaches the tolerance value. SOLUTION: A brazing objective work 10 is carried into a brazing position and, a position of the brazing unit 5 is decided by the control of the brazing member feeding volume control unit 9. A neighboring area of the brazing objective work 10 is pre-heated by a burner flame. When a surface temperature measured by a radiation thermometer is judged to be higher than the temperature threshold value, the general control unit 4 issues an order to the brazing member feeding control unit 9 to feed a brazing core wire to the jointing part. An ACCD camera of a measuring unit 6 catches an image signal based on the reflected light from the mirror face of the jointing part and converts it to calculate the feature volume of the brazing fusion area and the like. When the feature volume exceeds the threshold value, the brazing member feeding control unit 9 stops the feeding of the brazing member.

Title: Surface elastic wave element
Inventor: FURUYA NOBUAKI
IPC: H03H9/145
Filed: 1978-12-20
Abstract: PURPOSE:To expand a passing band by increasing signal intensity at any other frequency than a center frequency, by inserting different-interval parts partially into a periodic reflection grooves. CONSTITUTION:Parts 3-5 and 3-6, and 5-5 and 5-6 of periodic reflection grooves of reflectors 3 and 5 have an interval of 3/2Xlambda0 differing from others. In case of an equal interval, reflected waves in respective reflection grooves are in phase at frequency f0, but when f1>f0>f2, a rotation phase turns more the farther the groove is and signal intensity decreases at all grooves. In this constitution, the phase of the reflection in a groove farther than different-interval parts lags by 180 degrees and is out of phase to decrease composite amplitude at frequency f0, decreasing signal intensity. Further, when frequency f1>f0>f1, vectors 17-6-17-10 of a reflected wave from a different-period part are 180 deg. out of phase to increase composite vector 18, increasing signal intensity. In this way, a filter with a flat passing band part can be manufacture.
