Abstract: PURPOSE:To simplify the process by using a focussed ion beam ion implantation method in forming a double-structure guard ring section, and controlling the acceleration voltage for the ion implantation respectively on the outer side part, intermediate part and inner side part. CONSTITUTION:In forming a double-structure guard ring section 10, Be ions are implanted by a focussed ion beam ion implantation method, first into an outer side part 10E with an acceleration voltage for ion implantation of 80keV, then into an intermediate part 10M with the acceleration voltage being continuously and sequentially increased from 80keV as going into the inner side end becoming 100keV when an inner side part 10I is reached, and subsequently into the inner side part 10I with 100keV, whereby control is made so as to enable the formation by one ion implantation. With this, the part having a negative curvature becomes more smooth, the process is simplified, and the yield improves, whereby a semiconductor photodetector can be obtained which has a high performance and is excellent in mass production.

The mixt. is reacted with hot Cl 2  introduced through the lower part of the chlorinator 10, passing through a chlorine-inducing box 8, which collects Cl 2  produced at the carbon anode 3 of a V-shaped molten salt electrolytic cell 1 (which is made of iron and is used simultaneously as a cathode) heat-insulated with insulating material 6, and chlorine-inducing pipe 9, thereby producing AlCl 3 , which falls into the electrolytic cell 1 together with alkali (-earth) metal as a eutectic material. The cell 1 is maintained at a temp. 700W800°C and the product Al is drawn out through a taking out nozzle 4, and the bath material through the nozzle 5 heated by a heater 14. Hereby fuel consumption is reduced because uncalcined alumina is used and the electrolytic bath temp. is low.

Abstract: PURPOSE:To provide the combined station press device with which the formation of compact transfer press device and progressive molding press devices is possible by disposing >=2 lines of the same molding lines symmetrically with each other and driving these molding lines synchronously with each other. CONSTITUTION:The two right and left molding lines 12A, 12B provided in a frame 11 are disposed line symmetrically with each other and are driven synchronously with each other. The molding actions in the respective stations 101 and 201, 102 and 202 facing each other are, therefore, synchronized with each other between the lines 12A and 12B and the working loads thereof are equal to each other. This signifies that, although the working loads generated in the respective molding devices in a series of molding processes vary, the loads acting on the frame 11 are line symmetrical with respect to the center line C thereof. As a result, the action of the eccentric loads on the frame 11 is not admitted and, therefore, the design rigidity of the frame 11 is made lower than heretofore and the formation of the compact transfer devices 10 is possible.

Title: Spectroscopic device
Inventor: TANIGUCHI KAZUO
IPC: G01J3/06
Filed: 1981-02-28
Abstract: PURPOSE:To prevent the change in the visual line direction for viewing a light source from a spectroscope by fixing an incident slit and a diffraction grating and moving an exit slit. CONSTITUTION:When a slider C is moved in the direction of a groove V, an exit slit S2 moves to S2', S2''. At this time, the angle theta assumed by the grooves V and U is held fixed, and since the groove V goes toward the center of a grating G and the groove U passes through one point P on a Rowland circle R, the angle theta is the exterior angle of the circumferential angle spanned for the chord GP on the Rowland circle R, hence the slit S2 moves along the circle R, hence the slit S2 moves along the circle R. A scale is provided to the groove U, and the position of the pin P is measured, from which P S2 is determined, whereby wavelength is measured. In this case, an incident slit S1 and the grating  G are held fixed and therefore it is possible to prevent the change in the visual direction for viewing the light source from the spectroscope.

Title: Bearing device
Inventor: NAGAYAMA TAKASHI
IPC: F16C33/66
Filed: 1992-02-17
Abstract: PURPOSE:To maintain the replaceability of used and new grease, and prevent grease leakage from a labyrinth gap by providing a grease amount adjustment chamber in communication with either a waste oil chamber or an annular grease filling chamber at an opposite side, at a position off the oiling port of the annular grease filing chamber. CONSTITUTION:There is provided a grease amount adjustment chamber 19 communicated with a waste oil chamber 14 from a grease filling chamber 11 at the side of an oiling port 15. Also, one or more chambers 19 are formed at a position farthest from the oiling port 15 in the chamber 11. Grease fully charged into a bearing 3 as a result of oiling is forced out due to the rotation of the bearing 3 and overflows into the chamber 11. A labyrinth gap 17, however, has leakage resistance and the grease is forced out into the grease amount adjustment chamber 19 having less leakage resistance. Thus, there is no grease leakage from the gap 17 to the inside of a machine. According to this construction, used grease can be replaced by new grease via oiling, and there is no grease leakage into the labyrinth gap 17, thereby enabling maintenance workability to be improved.

Title: Digital pll circuit
Inventor: IKEDA YUICHIRO
IPC: H04L7/04
Filed: 1992-02-18
Abstract: PURPOSE:To reduce the jitter of an output signal by calculating a gradient from two samples, discriminating whether the gradient is 0 or positive or negative, and outputting a control signal for a VCO depending on the result of discrimination. CONSTITUTION:A gradient calculation circuit 2 calculates a gradient being a difference between two samples of a 2-point sampling circuit 2. Then a discrimination circuit 3 discriminates whether the gradient outputted from the gradient calculation circuit 2 is 0 or positive or negative, and outputs a control signal for a VCO 6 depending on the result of discrimination. For example, when the two samples are equal to each other and then the gradient calculated from them is 0, since it is considered that two sampling points are symmetrical with respect to a level peak point, it is discriminated that the phase of an input signal I and an output signal O of the VCO 6 are coincident and a control signal C to keep the frequency is outputted to the VCO 6.
