Patent JP-S61295616-A (JP)
Title: Electromagnetic device
Inventor: KAKEHASHI HIDENORI
IPC: H03F9/00
Filed: 1985-06-25
Abstract: PURPOSE:To reduce the magnetostrictions of the amorphous magnetic thin bands into 0 or the vicinity of 0 and to maintain the symmetrical property of the hysteresis curve generating in each amorphous magnetic thin band by a method wherein a capacitor is provided bteween the intermediate lead-out conductor of the primary winding of an oscillating transformer and the grounding conductor thereof. CONSTITUTION:A capacitor C is provided between the intermediate lead-out conductor of the primary winding of an oscillating transformer ST, which is constituted of saturable cores consisting of amorphous magnetic thin bands, and the grounding conductor thereof. However, when a DC electric power E is being impressed on the circuits and the electric power E is turned OFF, the oscillation operation is made to gradually extinguish by the charge being stored in the capacitor C and the residual magnetic flux is dwindled into 0 or the vicinity of 0. As the residual magnetic flux Br is left to stand in 0 by the circuits, the symmetrical property of the hysteresis waveform is held and the effect of preventing an abnormal waveform from generating can be obtained. The symmetrical property of the hysteresis waveform is maintained in such a way, and at the same time, the waveform is a high-angle type and can be obtained in low loss because of the amorphous magnetic thin bands, and furthermore, the waveform distortion is eliminated, and moreover, the highly reliable saturable cores can be realized.

Title: Method of manufacturing self-starting type short-arc rare gas discharge lamp
Inventor: NAKAMURA NOBORU
IPC: H01J9/395
Filed: 1977-11-17
Abstract: PURPOSE: To prevent adhesion of molten fuse substance to the top of electrodes, by supplying current to the fuse while evacuating the inside of lamp, thus heating the fuse to the recrystallizing temperature of fuse constituting metal, and then filling and sealing rare gas in the lamp.  
     CONSTITUTION: After completion of sealing, bulb 14 for constituting a discharge lamp is connected via air drawing tube 15 to an air drawing circuit. While evacuating the inside of this bulb 14 to a high vacuum of, for instance, 5.0×10 -5  Torr, current is supplied to fuse 19 via external lead rods 17, 18, whereby it is heated to the recrystallizing temperature of the fuse constituting metal and thus fuse 19 is molten as shown at 13. After cooling the fuse to room temperature, evacuation of air is stopped, and highly pure xenon is filled in the bulb through tube 15, until pressure of xenon reaches a predetermined level. Then, base portion 20 of tube 15 is sealed. For instance, in case that a self-starting type short-arc rare gas discharge lamp is started with an instantaneous current of 150 A which causes melting of fuse 19, fuse melting time is 0.4W4 msec, although it varies with the cross sectional area of fuse 19, and there was no adhesion of molten fuse substance.

Filed: 1991-05-15
Abstract: PURPOSE:To provide the gamma correction circuit which can set an amplification degree without depending on an input voltage. CONSTITUTION:A first feedback circuit including a transistor 11 and a resistor R1 and a second feedback circuit including a transistor 12 and a resistor R2 are connected to a differential amplifier circuit 10. When the level of an output voltage VA from the differential amplifier circuit 10 is lower than a polygonal point setting voltage V1, the transistor 12 is turned off and the differential amplifier circuit 10 is turned to a negative feedback amplifier circuit. When the level of the output voltage VA from the differential amplifier circuit is higher than the diagonal point setting voltage V1, the transistor 12 is turned on and the differential amplifier circuit 10 is turned to a voltage follower. Thus, the gamma correction circuit can be obtained to set the amplification degree without depending on an input voltage VIN.

The cylinder is made of fiber- glass and has a prescribed thickness. A photosensitive layer, which becomes acid- proof when exposed to light, is coated on the electroconductive metal layer 2. The photosensitive layer is covered with meshes consisting of line parts, which are pervious to ultraviolet rays and correspond to coil parts, and other line parts which intercept ultraviolet rays and corredpond to coil gaps. Ultraviolet rays are then irradiated to print a coil pattern. The pattern is developed to leave only light- irradiated parts as anti-etching layers 3. Etching is then effected by a solution of iron chloride or the like to remove exposed layer parts 2 to manufacture a coil only under the layers 3. The layers 3 are removed. To manufacture a multilayer coil, such a process is repeated.
