IPC: B23B1/00
Filed: 1984-01-30
Abstract: PURPOSE:To prevent a tool from breakage and a work from damage, by causing the tool to perform an escape motion after it performs cutting of the work to its root so that the tool may be moved by a preset distance to the resultant direction formed by components in both directions of X- and Z-axis. CONSTITUTION:A lathe, when it performs cutting of a work, causes a tool placed in an initial position A to machine the work in a depth of cut by a predetermined distance at a certain angle and reach a point B, then performing rough cutting from the point B to a point C along a Z-axis. Next the lathe, after it performs rough cutting from the point C to a point D along an X-axis, quickly feeds the tool from the point D to a point E along the Z-axis and moves the tool from the point E to the point B along the X-axis. Subsequently, the lathe, further cutting the work at the above described angle by the tool moving from the point B and arriving at a point F, performs rough cutting from the point F to a point G parallelly to the Z-axis. Thereafter, the lathe similarly transfers the tool to the point C so as to feed it to a point J by moving the tool to be fed by a preset distance in the resultant direction formed by components in both directions of the X- and Z-axis.

Title: Earthquake forecast by receiving ratio wave of sign of earthquake
Inventor: TAKAHASHI KOZO
IPC: G01V1/00
Filed: 1987-01-27
Abstract: PURPOSE:To establish an earthquake forecasting method at a relatively small expense and in a short preliminary observation period in an arbitrary region by shielding ground electric wave by using the casing steel pipe of a deep well or the like as the linear element of a monopole antenna and using a conductive plate mounted on the ground surface or the like as a reflector for the linear element. CONSTITUTION:The casing steel pipe of a deep well or a conductive cable inserted inside the steel pipe is used as the linear element 1 of a monopole antenna and a conductive plate or not mounted on the ground surface is used as a reflector 2 for the linear element 1. Underground electric wave 5 of the sign of an earthquake generated near a seismic center 4 is transmitted underground 7 and, directly or after reflected from the reflector 2 mounted on the ground surface, arrives at the linear element 1 to be detected by a receiver 3. On the other hand, most of electric wave 6, such as artificial noise or atmospherics, in atmosphere is reflected from the reflector 2 and the wave 6 partly arrives at the linear element 1 after attenuated in the underground 7. Thus, the ground waves are shielded and reception intensity difference between the underground wave generated as the symptomatic phenomenon of the earthquake and the other waves is increased whereby the wave of the sign of the earthquake is received, discriminated and detected and the earthquake is forecast.

Title: Manufacture of heat resistant insulated coil for electric equipment
Inventor: TSUNASHIMA EIJI
IPC: H01F41/12
Filed: 1988-01-26
Abstract: PURPOSE:To improve yield of resin, by impregnating an insulated coil with a thermosetting resin containing heat soluble capsules in which a curing catalyst is enclosed, and thermally curing the impregnated resin. CONSTITUTION:An insulated coil 12 having an insulating tape 11 wound on a coil conductor 10 and mounted on an electric equipment is impregnated with a thermosetting resin 13 containing heat soluble capsules in which a curing catalyst is enclosed. When the impregnated resin is cured by heat, the heat soluble capsules are dissolved by the heat and the curing catalyst flows out of the capsules into the thermosetting resin 13. Thus, the curing of the resin 13 is accelerated by the effect of the curing catalyst. In this manner, the resin can be thermally cured without causing run-off. Further, the curing catalyst is not brought into direct contact with the resin 13 until the resin is thermally cured, since it is enclosed in the capsules. Therefore, the curing of the resin is not accelerated prior to the impregnation and deterioration of yield of the resin can be prevented.
