Title: Optical waveguide device and its production
Inventor: IWASAKI MASAAKI
IPC: G02B6/42
Filed: 1991-11-07
Abstract: PURPOSE:To provide the optical waveguide device for connecting optical waveguide elements and optical fiber terminals capable of simplifying the high- accuracy alignment of optical axes in optical packaging and coupling the optical waveguides and the optical fibers with low loss without adjusting taking reliability and productivity into consideration. CONSTITUTION:Projecting solder 17 called solder bump is formed on metallic pads 15 of the end face of the optical waveguide element and is tentatively connected in such a manner that the metallic pads 16 on the end face of the optical fiber terminal come partly into contact with the solder bumps 17. V- grooves 14 for arraying the optical fibers with the optical waveguides 12 are automatically moved and fixed to the normal positions by the self-alignment effect generated by the surface tension of the molten solder 18 when the bumps 17 are melted by heating and, therefore, the optical waveguides and the optical fibers are coupled to each other simply by butting the optical fibers 19 along the V-grooves.

IPC: G11B27/02
Filed: 1989-11-08
Abstract: PURPOSE:To edit a sound fully electronically by adding the same address codes to a magnetic film capable of traveling in perforation synchronism with a movie film and a sound signal corresponding to the magnetic film. CONSTITUTION:When the movie film 2 to be edited and the magnetic film 3A to be edited where a time code signal is recorded are made to travel simultaneously, a sound signal part to which the same time code signal as the time code signal from a film editing machine 1A is added is reproduced and displayed on the monitor 23 of a console panel to know which part of which kind of sound is being reproduced at a glance. A time code display device 49 corresponding to an image projected on a viewer 4 is fitted on the film editing machine 1A and the same time code is displayed on the monitor 23 and a time code display device 49. The video film to be edited is made to travel continuously, an unnecessary part such as an NG scene is deleted, and the film is joined again.

Title: Contact electrode structure
Inventor: OKANO TATSUHIRO
IPC: H01L21/66
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To improve load resistance of an electrode, by constituting a leading end part of the contact electrode of an annular and an island-shaped contact parts. SOLUTION: A leading end part of a contact electrode 18 is formed to have an annular contact part 18b and an island-shaped contact part 18a. When a conduction inspection is carried out to a body to be inspected with a predetermined load applied to the contact electrode 18, a contact load acting to the leading end part of the contact electrode 18 is divided to the annular contact part 18b and island-shaped contact part 18a, thereby preventing an electrode crush at the leading end part of the contact electrode 18. Further, when the leading end part of the contact electrode 18 comes in touch with an electrode of the body to be inspected, the contact becomes a linear contact at the annular contact part 18b and a point contact at the island-shaped contact part 18a.  Even when an aluminum oxide film is formed on a surface of the pad electrode of the body to be inspected, the island-shaped contact part 18a easily breaks the aluminum oxide film of the pad electrode. A load resistance of the contact electrode can accordingly be improved without changing a material of the contact electrode, and the inspection is made sure and improved in reliability.

Title: Superconducting passive element
Inventor: YAMADA TOSHIRO
IPC: H01F17/00
Filed: 1987-11-18
Abstract: PURPOSE:To make it possible to implement a high inductance element in a small packaging area, by magnetically connecting between a closed loop formed of a conductor showing superconductivity and an open loop formed of a conductor showing superconductivity or normal conductivity. CONSTITUTION:Open and closed loops are made by sputtering a sintered YBa2 Cu3O7-delta target in a mixed gas atmosphere of Ar and O2 by n high frequency planer magnetron sputtering, using a sapphire monocrystalline substrate as a substrate to attach a superconduetive thin film formed of crystalline YBa2Cu3 O7-delta on the substrate and then patterning it by a print method or photolithography. When a current in the open loop 3 is increased, a permanent current flows in the closed loop 4 and a magnetic field is generated in a direction reducing the magnetic flux by a superconductive closed loop 4. As a result, a current flowing in the open loop is prevented. Therefore, an effective inductance between the input and output terminals 1 and 2 of the open loop 3 is increased.

Title: Surface treatment equipment using radiant-light
Inventor: OMURA KAZUMICHI
IPC: H01L21/027
Filed: 1985-12-24
Abstract: PURPOSE:To obtain the uniform irradiation of a radiant light through a window, by forming a radiant-light permeation window consisting of a curved surface shell in the manner in which the window thickness is made uniform for every part. CONSTITUTION:Assuming that the inside radius of a radiant-light permeation window 17 constituted of a curved surface shell be (r) and its thickness at the center be (t0), the window 17 is formed in the manner in which the vertical thickness (t) to the surface at an angle theta from the center, t (t=t0costheta), is made uniform for every part. The maximum of thetaM is, in general, less than 90 deg., and so the thickness in the vertical direction is smallest. Thus the radiant light having transmitted through the window 17 is made uniform in irradiation, and the strength of the window 17 can be increased, because the window 17 is formed by a curved surface.

Abstract: PURPOSE:To heighten the efficiency of data transfer by predicting the number of information frames expected to be transferred within the next prescribed time based on the counted result of the number of information frames, and deciding the transmission timing of a reception monitoring frame for a reception information frame based on the above prediction. CONSTITUTION:At communication control units A and D at both ends which perform the HDLC procedure of a data communication line, the number of information frames transferred at every prescribed time is counted, and the number of information frames expected to be transferred within the next prescribed time is predicted based on a count result. And an appropriate timing value corresponding to the prediction is set on a timer, T2 to transmit a receivable response frame. Thereby, an appropriate response corresponding to the quantity of data communication can be obtained, and the data transfer can be performed efficiently. In other words, it is possible to perform efficient data communication based on the selection of the prescribed time to count the I frames of reception and transmission, the count value used in judgement to decide a value to be set on the timer T2, and a setting value on the timer T2.

Filed: 1986-12-10
Abstract: PURPOSE:To automatically obtain plural types of copies at one copying operation and automatically copy on two types of copying paper from one face to be copied by inputting plural types of sheets at a time. CONSTITUTION:A both side mode or a composite mode is set by a key and, as printing is started through a start key 55, C1 sheets of first-side copied paper enter a both side tray 22. At this time, the reading of a sheet counting counter C6 is increased to, C1=C6.

And, after carrying out C1 times of second side copying, the sheets of paper are discharged. At this time, the reading of a counter C0 for detecting the number of sheets of paper in the both side tray is decreased to zero. When this operation is over, the copying mode returns to a first side mode.
