Title: Electronic copying device
Inventor: SETO SUSUMU
IPC: H04N1/00
Filed: 1985-10-11
Abstract: PURPOSE:To obtain a recorded picture having the high position accuracy by confirming optically the positioning relation between a recording means and a means which projects pictures on a writing medium. CONSTITUTION:The cuts 14 and 15 are provided at both ends outside the picture area of a slit plate 8 fixed to an electronic copying device main body as the reference mark projecting members. While a recording means 4 positioned and attached mechanically to the copying device has the confirming parts for the projected images of the reference marks at the positions corresponding to the cuts 14 and 15 serving as the reference marks of an incident surface part 13. Then marks 16 and 17 are provided to said confirming part in response to the reference marks. Thus it can be easily confirmed whether the means 4 is positioned at a proper place or not according to the coincidence or discordance between the images of the cuts 14 and 15 of the slit 8 and the marks 16 and 17 respectively. In such a way, the coincidence of positions is secured accurately between the means 4 and a writing medium on a production process or a maintenance/checking mode of the electronic copying device.

Title: Control circuit of pulse motor
Inventor: KIKUCHI TOSHIYUKI
IPC: H02P8/16
Filed: 1983-11-30
Abstract: PURPOSE:To save power consumption by always applying a high voltage to a pulse motor during slow-up and slow-down periods and alternately applying low and high voltages during the constant speed rotating period. CONSTITUTION:Since a control signal (d) is ON during a slow-up period T1, a high voltage E1 is applied. A main controller 1 turns OFF the control signal (d) during the constant speed rotating period T2. Thus, a control signal (b) having smaller pulse width merely turns ON and OFF a transistor TR from a timer 74, and a space motor drive voltage (c) alternately becomes high and low voltages E1, E2. The controller 1 turns ON the signal (d) during the slow-down period T3 of a space motor 8, and sets the space motor drive voltage (c) similarly to the period T1 at high voltage E1. Thus, drive power can be saved.

Abstract: PURPOSE:To reduce the drop-out of information by converting a dot adjacent to an isolated black hot dot into black dot data, and supplying it to a head when the transfer of the isolated black dot is stopped by a transfer control means. CONSTITUTION:The output of a P/S conversion circuit 5 is supplied to a head buffer 6 through a data transfer control circuit 15, and when the data transfer control circuit 15 detects the isolated black data, namely, it detects that continuous dot data of '0', '1', '0' from the P/S conversion circuit 5 are inputted, and when this isolated black data is the dot data of thinning timing, it converts the data of the first '0' into '1', and outputs it. Thus, the isolated black dot is detected in a main scanning (horizontal) direction, and when this dot is thinned by a transfer control signal, a white dot preceding this black dot is converted into the black dot data, and is transferred to the head buffer 6. Thus, the drop-out of information quantity can be reduced, and the quality of printing can be improved.

Title: Manufacture of semiconductor device
Inventor: KOUNO MICHIARI
IPC: H01L21/60
Filed: 1982-12-28
Abstract: PURPOSE:To simplify processes while improving accuracy on positioning by attaching a composite barrier metal layer of Ti(TiN)-Pd(Pt) groups on the whole surface of a wafer chip, removing a Pd(Pt) layer except the upper section of a pad electrode section and forming a gold bump through gold plating while using a TiO2 layer formed through an anodic oxidation method as a mask. CONSTITUTION:Ti (or TiN) and Pd (or Pt) are sputtered or evaporated on the wafer chip in succession to form a Ti layer 5 and a Pd layer 6, and the Pd layer 6 is left only in a section to which the Au bump is formed. A resist is applied, and patterned, only a section above an Al electrode, the section above the pad electrode section, is left, and the Pd layer 6 is etched while using the residual resist 7 as a mask. The Pd layer 6 is etched selectively, and the exposed Ti layer 5 is oxidized through the anodic oxidation method while using the residual resist 7 as a mask. The resist film 7 is removed, and the Au bump 9' is formed while using the formed TiO2 film 10 as the mask. The TiO2 film 10 is removed through etching by fluoric acid, and the Ti layer 5 is removed by an etching liquid consisting of a mixed liquid of oxalic acid and hydrogen peroxide water. Accordingly, since a resist need not be used as the mask on the formation of the bump, a process such as a photolithography process can be omitted, and accuracy on positioning can be improved.

Title: Magneto-optical recording medium
Inventor: KUWAE YOSHINORI
IPC: G11B11/10
Filed: 1986-09-29
Abstract: PURPOSE:To improve oxidation resistance and to permit an increase in rotating angle at the time of reproduction and an increase in area by coating plural pieces of fine magnetic particles having magnetic anisotropy with a low melting dispersion medium and dispersing the same in such a manner that the direction of the magnetization faces perpendicularly to the film surface of a high melting dispersion medium. CONSTITUTION:The fine magnetic particles 11 coated with the low melting dispersion medium 13 are dispersed into the high melting dispersion medium 14 existing in the form of a film in such a manner that the magnetization 12 faces perpendicularly to the film surface of the medium 14. The medium 13 is then melted by projecting light 17 thereto while an external magnetic field 16 is impressed thereto in the direction opposite from the magnetization 12 direction. Moment of rotation is then generated in the fine magnetic particles 11 in said region and the particles are inverted. The magnetization 12 is inverted as well. Recording points 18 are formed when the medium 13 is cooled to solidify while the magnetic field 16 is held impressed thereto. Since the need for decreasing the curie temp. of the fine magnetic particles is thereby eliminated, the limitation on the selection of magnetic materials is eliminated. As a result, the use of the fine magnetic particles having the excellent oxidation resistance is permitted and the longer life is attained. The magneto-optical recording medium having the large rotating angle is thus obtd.

Title: Ultrasonic probe and ultrasonic diagnostic device using the probe
Inventor: MURAI SEIICHIRO
IPC: G01N29/24
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of the diameter of a leading part by attaching a freely rotatable ultrasonic wave reception transducer composed of a piezoelectric element through a bend part on the tip side of the leading part composed of a flexible hollow member and installing an operation part for bending the bend part and a rotational drive control means on a base end side. SOLUTION: A driving means 24 composed of first and second piezoelectric elements is installed inside a tip part 14 formed on the tip side of the leading part of this ultrasonic probe 11 and a transducer 18 fitted inside the tip part 14 is rotationally driven. For the driving means 24 for electrically performing drive control, the insertion of a signal line 29 for impressing driving signals to the piezoelectric element in the leading part 12 is sufficient and the need of inserting a wire or a flexible shaft like the conventional one for mechanically performing rotational drive is eliminated. Since the diameter of the signal line 29 is smaller than the flexible shaft of the wire, the diameter of the leading part 12 can be made smaller for that portion. Thus, at the time of diagnoses, pains given to an examinee for whom the ultrasonic probe 11 is inserted into a celom are reduced.

Abstract: PROBLEM TO BE SOLVED: To support a housing box at a high position, and make the housing box serve as a step as well, and facilitate the loading on an automobile by turning downward a pair of handles which are axially supported near the bottom surface on a side surface of the housing box. SOLUTION: When this housing box 1 which works as a step as well, is used, front and rear members 3a, 3b are turned at 90 deg. with the axes 4a, 4b as the pivotal centers, and side surfaces A of side members 31a, 31b are brought into contact with the ground, and by doing so, the front member 3a and the rear member 3b are placed under an open state, and the top of the housing box 1 is opened. Under this state, when a lock 23 is removed, a lid 22 becomes openable/closable. In addition, when the front member 3a and the rear member 3b are turned to 180 deg., and the upper surface B is brought into contact with the ground, the front member 3a and the rear member 3b locate under a container 21 because the side members 31a, 31b are axially supported by axes 4a, 4b at a lower part, and the container 21 is lifted at a high position and supported.  Therefore, the upper surface of the container 21 is raised, and it can be used as a step of an appropriate height.

Title: Method for online grinding of rolling roll
Inventor: WATANABE YUICHIRO
IPC: B21B28/04
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To remarkably cut down the rate of occurrence of a plate profile abnormality by grinding after determining a target grinding quantity smaller than the estimated value of wear when grinding a noncontact part between a rolling stock and the roll according to the estimated value of the wear of the roll. SOLUTION: When setting the estimated value of the wear to a grinding quantity, there are some cases where a difference in level by wear is left over because of an error to an actual wear quantity, or excess grinding occurs. When a residual difference in level has occurred by the shortage of the grinding quantity in difference in level, since the difference in level by wear has a component canceling out thermal expansion, a profile whose apparent thermal expansion is small, is obtained. To the contrary, in the case of the excess grinding, for a composite profile, a profile whose thermal expansion is increased, is obtained. And, when performing width return rolling, especially in the case of the excess grinding, a quality abnormality with large edge build-up occurs.  Therefore, when determining the grinding quantity according to a roll wear estimation model, if the target grinding quantity is determined so that the shortage of grinding is obtained, not to obtain excess grinding by an estimated error, the rate of occurrence of an abnormal plate profile is reduced.
