Title: Dc power source display device
Inventor: YOKOYAMA MASAKAZU
IPC: G05F1/56
Filed: 1983-12-20
Abstract: PURPOSE:To inform a drop state of a voltage of a DC power source by operating a free running multivibrator by a transistor (TR) which has connected a Zener diode to the base, and flickering a light emitting element. CONSTITUTION:When a voltage of a DC power source 5 is high enough, a Zener diode 1 is turned on, and a switch TR2 is turned on. Therefore, the collector of the switch TR2 becomes about ''0''V, and a free running multivibrator 3 does not oscillate, therefore, a light emitting diode 4 does not flicker. Subsequently, when the voltage of the DC power source 5 drops gradually, and approaches the sum or below of the base-emitter voltage by which the Zener diode 1 and the switch TR2 are turned off, the Zener diode 1 becomes a cut-off, the switch TR2 is turned off,and the collector rises to the voltage of the DC power source 5. Therefore, the free running multivibrator 3 starts its oscillation, and the light emitting diode 4 flickers.

Title: Fixing of stator coil and rotary electric machine
Inventor: OZAWA MASARU
IPC: H02K3/47
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To improve heat radiating performance of a stator coil. SOLUTION: First, a stator coil 15 is internally inserted into a stator iron core 17. Next, these are soaked as they remain integral in the vanish tank to allow penetration of vanish into the stator coil 15 and thereafter these are raised. Next, a mandrel 33 having formed an external circumference pressing portion by winding the fluorine rubber to the external circumference of a mandrel body 35 consisting of the fluorine resin is inserted to the stator coil 15. Thereafter, the varnish is thermally hardened as the stator iron core 17, stator coil 15 and mandrel 33 remain integrated. Thereby since the external circumference pressing part 37 is projected or recessed along the internal circumference of the stator coil 15, the vanish is hardened keeping the projected and recessed portion at the internal circumference of the stator coil 15.  Thereby, substantial internal surface area of the stator coil 15 increases to improve the heat radiating property.

Title: Method of forming layer
Inventor: DOBSON CHRISTOPHER DAVID
IPC: H01L21/683
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To protect a tense film against fissures when moisture is removed from it by a method wherein a tensile stress is imposed on a wafer, and a tense layer is attached to a layer where stress is imposed to release the wafer from stress. SOLUTION: The upside 11 of a wafer 13 is convex, so that a tensile stress is imposed on the wafer 13 when the wafer 13 is fixed to an electrostatic chuck 10. Then, a seed layer 14 is attached to the wafer 13 before the wafer 13 undergoes stress. When the wafer 13 is subjected to stress, a tense layer 15 is attached to it. Then, the layer 15 is hardened (or can be hardened) or set (or partially set). When the layer 15 is kept in a desired state, the wafer 13 is released from the chuck 10 and turned to an original flat state. Doing as mentioned above, the chuck 10 keeps the layer 15 in a state that the layer 15 undergoes a compressive stress so as to resist stress inside it. By this setup, when moisture is removed, the wafer 13 can be protected against fissures.

Title: Planar type triac and manufacture thereof
Inventor: KITANO HIROBUMI
IPC: H01L29/747
Filed: 1994-10-05
Abstract: PURPOSE: To enhance the trigger sensitivity without sacrificing a forward withstand voltage. CONSTITUTION: An N2-type layer 5 connected to a T1 electrode 31 and an N4-type layer 6 connected to a gate electrode are selectively formed at the exposed surface of a P2-type layer 3 formed selectively on the upper main surface of an N-type semiconductor substrate. A P3-type layer 41 is so selectively formed on the exposed surfaces of an N1-type layer 2 as to be disposed adjacently to the region P2 a of the layer 2 so sandwiched between the layers 2 and 6 approaching one another. A depletion layer S1 reproduced on a semiconductor substrate in a positive shut-off state is scarcely invaded into the interior in the vicinity of a boundary between the layers 3 and 41. That is, the invasion of the layer S1 to the region P2 a is suppressed by the layer 41.  Thus, the width D3 of the region P2 a is set narrowly to enhance the route resistance of a trigger current without deteriorating the forward withstand voltage, and the trigger sensitivity can be improved. In this manner, the sensitivity can be enhanced without sacrificing the forward withstand voltage.
