Abstract: PROBLEM TO BE SOLVED: To improve discharging capacity and charging discharging characteristics such as charging/discharging cycle life by using an amorphous oxide and/or chalcogenide baked in the atmosphere adjusted in optional oxygen partial pressure as a negative electrode material. SOLUTION: An amorphous oxide and/or chalcogenide of a negative electrode material are/is obtained by baking, and the baking atmosphere is either one of the states that the equilibrium of the raw material oxide and/or chalcogenide is inclined to the oxidation side and it is inclined to the reduction side. The value of oxygen partial pressure represented by -log (P02 /atm) is the range of 1-20, or 5-17, or 10-17. By baking the negative electrode material in the atmosphere in which oxygen partial pressure is optionally adjusted, the structure and the surface state of the negative electrode material are made good, and when the negative electrode material is used in a battery, the cycle life is lengthened and the capacity is increased.

IPC: B29C45/26
Filed: 1989-04-21
Abstract: PURPOSE:To enable the accurate positioning of an electronic component by a method wherein a first and a second mold are made to relatively approach to each other, the slope of one of pressing pieces moves one of the ends of electronic component leads inward by pressing, and the electronic component is positioned at a prescribed position inside the first mold by finishing the movement of the electronic component by pressing at the time when or before the closing of the first and the second mold is finished. CONSTITUTION:When a cope 30 and a drag 10 are made to approach each other, the lower ends of jumping preventive parts 50 and 52 are made to bear on the upside 58 of the drag 10 to prevent a diode 12 from jumping up. Keeping them in this state, when the cope 30 and the drag 30 are made to approach each other closer resisting the energizing force of an energizing means which energizes the jumping preventive parts 50 and 52 downward, the slope 46 of pressing member 34 out of pressing members 34 and 36 correspondent to the offset side of the diode 12 is made to bear on a lead 20 of the offset side, whereby the tentatively positioned diode 12 is moved to a prescribed position by pressing through the movement of the pressing member 34 toward the direction of the drag 10 (direction of an arrow B). When both the ends of the diode 12 change from abutting against the slope 46 or 48 to abutting against vertical faces 42 and 44, the positioning of the diode 12 is finished.

Title: Ion implantation device
Inventor: SUGIMURA SHINICHI
IPC: H01J37/05
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an ion implanter capable of reducing a quantity of undesired ions to be implanted into a wafer. SOLUTION: An inactive gas housing part 42 for containing inactive gas atoms thereon is formed between an ion generator 12 and a mass spectrometer 14. Ions, which are accelerated by an extraction electrode 26 and extracted from the ion generator 12, are put into and made to pass the inactive gas container 42. By passing the inactive gas housing part 42, only undesired ions are made to collide against the inactive gas atoms, to be decomposed into atom ions having a smaller mass or converted into ins having a different valence. Even if the decomposed or converted ions enter the mass spectrometer 14, they cannot pass the mass spectrometer 14 since they follow on an orbit different from that followed by the desired ions which are expected to pass the mass spectrometer 14.  Consequently, it is possible to reduce the concentration of impurities which are accelerated and implanted into a wafer disposed downstream of the mass spectrometer 14.
