Patent JP-H03254046-A (JP)
Title: Micro-size vacuum tube and its manufacture
Inventor: IZUMI MOICHI
IPC: H01J19/04
Filed: 1990-03-01
Abstract: PURPOSE:To allow hot electrons to run parallelly to a base board and enhance the efficiency of hot electron emission by constructing at least either of a cathode electrode and an anode electrode in the form of an acute cutting edge. CONSTITUTION:An i-layer 2 is formed by a semi-insulative base board. A metal layer 3 having high hot electron emission coefficient is deposited by the vacuum evaporation method, etc., and thereon resist 7 is applied. The resist 7 is subjected to the window forming etching process in an amount corresponding to the distance at which a cathode and an anode electrode are desired separated. With the resist 7 and metal layer 3 used as mask, the i-layer 2 is subjected to etching for producing undercut so that the side of metal layer 3 nearer the semi-insulative base board 1 is sharpened with retreat etching of the resist 7. A lower grid electrode 4 is formed by means of vacuum evaporation or sputtering, and then the resist 7 is removed to form cathode electrode 5, anode electrode 6, and upper grid electrode 4. Thus a micro vacuum tube is achieved.

Title: Optical reproducing device
Inventor: MORITSUGU MASAHARU
IPC: G11B11/105
Filed: 1982-03-30
Abstract: PURPOSE:To obtain detection sensitivity having high accuracy, by detecting a state variation of light which repeats reflection by a photomagnetic disk plural times, and reading the information. CONSTITUTION:A reflecting device R having a total reflector 8 is provided on the upper part of an objective lens 6. Laser light passes through a hole 10 of the reflecting device R, is condensed to one point 9 of a magnetic recording medium 1, is reflected, passes through the lens 6, passes through a reverse optical path again by the total reflector 8, and is returned from the hole 10, by which information is read. In this case, the laser light is influenced by a magnetic field 2 times from the medium 1, therefore, by a magnetooptic Kerr effect, the polarizing face is rotated on a comparatively large scale. Therefore, detection sensitivity having high accuracy can be obtained, and an S/N ratio is improved.

Title: Focusing lens driving mechanism
Inventor: ARISAKA KUNIO
IPC: G02B7/08
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized focusing lens driving mechanism which can be loaded inside such a small space as a zoom lens barrel. SOLUTION: When a step motor SM rotates, rotation is transmitted to a rack 4a through gear trains 15 to 20, a focusing lens frame 4 turns right, and the frame 4 is extended by a helicoid gear. A coil frame 27 rocks when the projecting piece 4b of the frame 4 pushes the projecting piece 27a of a coil frame 27 in this process, and the detection piece of a shutter blade opens/closes the reflection optical path of a photoreflector. The original point of the frame 4 is confirmed by the signal of the photoreflector and extending amount is controlled.  Since an intermediate ring for fine adjustment of a position does not exist, entire size can be miniaturized; and since a compensating value is incorporated in step number for extending the frame 4, exact positional accuracy can be obtained without mechanical fine adjustment, and a lens is not damaged in accordance with the fine adjustment operation.

Title: Welding method for zinc plated steel plate
Inventor: OONISHI HARUHITO
IPC: B23K9/235
Filed: 1981-04-08
Abstract: PURPOSE:To improve weldability in welding of zinc plated steel plates by heating only the part near the weld zone to prescribed temp., and spot-welding or seam-welding the same immediately thereby converting the zinc plating layer near the weld zone to an iron-zinc alloy layer. CONSTITUTION:Just prior to welding, only the part near the weld zone is heated to 500-600 deg.C to diffuse iron into zinc and to convert a pure zinc plating layer to an iron-zinc alloy layer, thence immediately the steel plates are spot-welded  or seam-welded. The reason for limiting the heating temp. lies in that at these temp. the diffusion of iron into the zinc layer is extreme. The reason for heating the steel plates just prior to the welding lies in that in <=10sec the iron-zinc alloy layer is not sufficiently formed, and in >=200sec the iron content increases too much and peels like powder.

Abstract: PURPOSE:To eliminate the need for a private disconnecting switch for three-phase shoft-circuit braking and to reduce space by closing all of phase change-over disconnecting switches in case of operation of a generator and in case of operation of a motor and a single-pole single-throw disconnecting switch for short-circuit braking when braking. CONSTITUTION:Phase change-over disconnecting switches 7G, 7M, 7C in case of operation of a generator and in case of operation of a motor are mounted at the power system side of the armature winding 1A of a synchronous machine 1 while a single-pole single-throw disconnecting switch 7B for short-circuit braking is installed. All the disconnecting switches 7G, 7M, 7C, 7B are closed after they are brought to nonload nonexcitation conditions when braking, and exciting currents are given to field winding 1B, thus flowing short-circuit currents through the armature winding 1A. Consequently, a private disconnecting switch for three-phase short-circuit braking need not be used only by changing the constitution of the phase change-over disconnecting switches according to conventional systems, space is reduced and a brake gear can be manufactured economically.

Title: Ground device for railway rolling stock
Inventor: MEJI TETSUO
IPC: B61F15/12
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent occurring of galvanic corrosion of a bearing when a large amount of electric current is passed and to improve maintainability, by forming a through-hole in a front lid of a shaft box, securing a slip ring abutting to an end surface of an axle to this through hole, and slidingly bringing a ground brush contact with the outer end surface of the slip ring. SOLUTION: A through hole 8 is formed between bolts 7 of a front lid 6 of a shaft box, and a slip ring 9 is mounted to the outside of the front lid 6 of the shaft box by a bolt 10. A ground brush 11 is slidingly brought into contact with the outer end surface 9b of the slip ring 9 to constitute a ground device 15 with the slip ring 9 and the ground brush 11. Current from various electric apparatuses is guided to an axle 2 through the ground brush 11 and the slip ring 9, and flows to a running rail, a return line, through the axle. Therefore, the current is guided to the axle 2 directly without passing through a bearing 5. Thus, a fear of occurring of galvanic corrosion on a bearing is eliminated even when a large amount of electric current is passed, and maintainability can be improved.
