Abstract: PURPOSE:To form a high precision helicoidal surface without any alignment of a center point by setting a distance between a rotary tool spindle and a tapping spindle to the same as a finished size, and tapping via the micro-shifting of the rotary tool toward the helicoidal tangent of a screw for every stroke of a workpiece toward the tapping spindle. CONSTITUTION:A distance (d) between the tapping spindle (l) of a workpiece 1 and the spindle (m) of a tool 2 is made the same as a finished size. And an angle theta between the center face (beta) of the tool 2 and the sectional face (a) orthogonal with the spindle (l) of the workpiece 1 is set to the same as the helix of a screw to be formed. Therefore, said face (b) includes the tangential line (f) of the helix. The workpiece 1 gives reciprocating helical motion, while rotating toward the tapping spindle (l) and for every stroke of the motion, the rotary tool 2 is gradually fed from a dotted line position to a solid line position in a helical line tangent direction. According to the aforesaid constitution, it is unnecessary to align the rotary tool 2 and a high precision screw surface can be formed without the high precision of tool and workpiece retaining mechanisms. Also, said tool 2 and workpiece 1 can be easily mounted to a machining device.

Inventor: NISHIJIMA YASUTSUGU
IPC: H01G13/00
Filed: 1990-03-16
Abstract: PURPOSE:To reduce the mechanical strain added to a bending part, and to make it possible to attach the bending part to the cathode surface of a capacitor element without generation of dead space by a method wherein the bending work of a cathode lead terminal is conducted in two stages. CONSTITUTION:The mounting legs 4a and 4b of a cathode lead terminal are bent at right angle, and an external lead-out lead wire 4c and the mounting leg 4b are bent at the prescribed angle. Then, the mounting leg 4b is bent at right angle to the lead piece 4c. To be more precise, the mounting legs 4a and 4b are bent in the neighborhood of the intended 90 deg. by the first bending process, and as the mounting leg 4b is preliminarily bent against the lead piece 4c, the squeezing force of a pressing blade is weakened when the mounting leg 4b is bent at right angle against the lead piece 4c in the second bending process. As a result, the formation of gap is unnecessitated, and the generation of curling can be prevented.

Title: Optical parametric oscillator
Inventor: ASAHA KAORU
IPC: H01S3/108
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to allow both high efficient wavelength conversion by an inner resonator and high output and single pulse oscillation compatible, by disposing a supersaturating absorber having supersaturating absorbing characteristics for the absorption of a fundamental wave between a pair of reflecting mirrors. SOLUTION: Since the second oscillation of a fundamental wave is suppressed by a supersaturating absorber 10, no wavelength conversion light is generated, and wavelength conversion light is oscillated by a single pulse. The first oscillation of the fundamental wave becomes strong pulse oscillation, since the energy stored in a solid state laser crystal 3 is large. The absorption of the absorber 10 is saturated for such a laser beam, and the absorption becomes substantially '0', and hence it does not affect the first oscillation. The second oscillation of the wave becomes weak pulse oscillation since the energy stored in the crystal 3 is small. The absorption of the absorber 10 is not saturated for such a laser beam, but large absorption is exhibited; and hence the second oscillation of the wave is suppressed, and no second oscillation of the wavelength conversion light occurs.

Filed: 1985-03-28
Abstract: PURPOSE:To give an adequate mechanical strength and improve performance of an electrode such as active substance utilization rate, by spreading a solution of a salt of monoatonic cation of a high polymer carboxylic acid over the surface, after soaking a solution of a metallic salt of diatomic or more, in the pores of a dried body of a metallic core spread with a specified paste, and then drying up it. CONSTITUTION:An active substance such as cadmium oxide, an electric conductor, an antialkaline short fiber, and a binder such as an organic paste or synthetic resin powder are mixed and kneaded together with a dispersion medium of water or an organic solvent to make up a paste. The paste is spread over a metallic core and dried up to form a dried body which has numerous pores remained after the dispersion medium evaporates. The pores of the body is soaked with a solution of a metallic salt of diatomic or more. Then a solution of a salt of monoatomic cation of a high polymer carboxylic acid is spread over the surface. In such a way, a membrane of a gel of solution of a high polymer carboxylic acid is formed over the electrode plate, and then dried up. Now a high polymer carboxylic acid salt is concentrated only over the surface of the electrode plate, causing to make the surface contain a large amount of binder to have a high strength, while the inner part of the plate contains little binder, resulting in a high porous property without losing a good active substance utilization rate.

Abstract: PROBLEM TO BE SOLVED: To remove a discomfort pattern of a low density region by selecting a processing region decided in response to a dot occupation ratio determined according to an input level of a low density region, checking a history of output data already binarized according to the selected region, and controlling the binarizing according to its output. SOLUTION: A uniformity processor 200 checks input data fmn at the time of binarizing in an error diffusing process. In the case of input data fmn >4, an output signal Si is set to '0', it is binarized. In the case of low density level of fmn <5, a selected region of an output data bit memory of already output data responsive to the input level is checked. If the past output is even once detected, the signal Si is set to '1', serial output ODmn is set to '0' irrespective of the processed result of a binarizing processor 401, and simultaneously the output data is processed as '0'. And, when a history of the '1' is not detected by the selected region check of the output data bit memory, the signal Si is set to '0'.
