Title: Electron beam welding method
Inventor: KOYAMA KUNIO
IPC: B23K15/00
Filed: 1988-09-02
Abstract: PURPOSE:To easily prevent spike defects at the time of partial welding by oscillating an electron beam to perform electron beam welding and carrying out the above-mentioned oscillation with specific amplitude in the range of the specific number of oscillations respectively in the orthogonal direction. CONSTITUTION:The electron beam is oscillated and projected in two directions on the orthogonal surface to its irradiation direction to perform welding. In the above-mentioned electron beam welding method, when the respective numbers of oscillations per second in the two oscillation directions of the above- mentioned electron beam are denoted by X, Y, in case X, Y are 50-10,000 times and either of those is <=1,000 times, the numbers of oscillations are regulated in the range to satisfy conditions shown by an inequality: logY <1.8551.logX-2.5697 or an inequality: logY>0.5391.logX+1.3851. In addition, in the case of X, Y 1,000 times, the numbers of oscillations are regulated in the range of satisfy conditions shown by an inequality: Y<0.99.X or an inequality Y>1.01.X. Further, the amplitude of the oscillation is made to 2-6mm on the surfaces of materials to be welded. By this method, the spike defects generated by partial welding of the welding finishing end, etc., are easily prevented.

Title: Magnetic memory element
Inventor: HIDAKA YASUHARU
IPC: G11C11/14
Filed: 1983-11-22
Abstract: PURPOSE:To obtain a means holding stably a VBL written as information on a striped main magnetic wall by providing a means impressing a rectangular wave magnetic field in the inner direction of a film in terms of a magnetic memory element utilizing a pair of vertical Bloch lines as an information unit. CONSTITUTION:An element utilizes a pair of Bloch lines 7 and 8 as an information unit. When a pulse bias magnetic field Hp is applied to the pair of Bloch lines, the lines rotate in such a rotational direction that a screw at left side is progressed in the direction of the magnetic wall inside magnetization Hp due to a gyroscopic effect, the Bloch lines 7 and 8 move in the left direction along a magnetic wall 6. When a pulse bias magnetic shape is decided, how the pair of the Bloch lines moves is automatically decided. After a tau0 has expired since the pulse bias magnetic field was impressed, the pulse bias magnetic shape Hp is impressed by a rectangular wave pulse face inside magnetic field Hip, and the Bloch lines are braked. As a result, the pair of the Bloch lines progresses by the prescribed bit interval. After impressing the Hip, the magnetic field is disconnected. After the Bloch lines have stopped in the location, the Hip is dis connected, and the Hp is applied. Then this procedure is repeated. Thus only a rise time and fluctuation are controlled in terms of a shape of a pulse bias magnetic field.

Title: Lead relay for micro-signal
Inventor: YOSHIDA SHINJI
IPC: H01H36/00
Filed: 1988-09-05
Abstract: PURPOSE:To make it possible to reduce or completely eliminate the leak current flowing over the surface of an insulation sleeve by forming a conductive layer on the external surface of the insulation sleeve, and installing a power source means to equalize the potential of the conductive layer with that of a lead switch contact point. CONSTITUTION:Conductor belts 3, 4 for guard having lead wires 9, 10 are wound around the surface of insulation sleeves 7, 8 in a way not to leave any gap between them respectively. The conductor belt 3 and a relay contact point 5 and the conductor belt 4 and a relay contact point 6 are respectively maintained at a same potential by applying a voltage of a same potential to the lead wires 9, 10 and relay contact points 5, 6. Since electric current does not flow between two conductors with the same potential, any leak current from a contact point lead 12 does not flow to the surface of the insulation sleeve 7. Similarly, no leak current flows from the contact point lead 13 to the surface of the insulation sleeve 8 which is held between the conductor belt 4 and the relay contact point 6. This enables to reduce the flow of leak current from contact points to the surface of insulation sleeves of relays.

Title: Side light type surface light source device, and metal mold for parts for side light type surface light source device
Inventor: ISHIKAWA TAKESHI
IPC: F21V8/00
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To avert the sticking of a optical control member to the exit surface by forming the exit surface to be a rouge surface in so that the degree of roughness on the side reverse from an end face side is made larger than on the end face side. SOLUTION: The 'fit' between the prism sheet 1 and the exit surface 12 by the projecting parts of the rough surface of a light scattering light transmission body 11 is lowered, by which the stocking of a prism sheet is effectively averaged. If, however, the exit surface 12 is formed as the rough surface, the exit light of the exit surface 12 is eventually corresponding scattered and the impairment of the directivity is resulted. If the exit surface 12 of formed as the purge surface in a range of 0.02 to 0.25μm in arithmetic average roughness, the stocking of the purism sheet is affectingly averted. The degradation of the fit is large nearer the front end side where the sheet thickness is smaller and, therefore, the rough surface rougher nearer the front end side of the light scattering light transmission body 11 is formed, by which the deterioration of the directivity is averaged and the sticking of the prism sheet is effectively averted.

CONSTITUTION:An inverter main circuit is composed of an AC power source 1, a power reactor 3, a smoothing reactor 4, a power inverter 5, an output terminal capacitor 6, a motor 7 and a speed detector 8. A controller is composed of a current controller 10, a pulse distributor 12, a comparator 13, a modulation wave amplitude calculator 14, a modulation wave generator 15, a carrier generator 16, a vector calculator 17 and a pulse distributor 18.

The value theta is input from the generator 15 to the gates of the inverters 5. Thus, since the amplitude of the modulation wave is varied in response to the load condition, the allowable minimum pulse width can be always obtained.
