Title: Intensive compacter
Inventor: SASAKI TOSHIHIKO
IPC: E01C19/48
Filed: 1993-10-15
Abstract: PURPOSE:To obtain a sufficiently compacted pavement in which the upper bed is stuck to the lower bed well, by dividing the thick pavement into two and compacting them separately. CONSTITUTION:A lower bed compacter 5 and an upper bed compactor 6 are disposed back and forth in the working direction and these are connected to each other detachably by a connector 7. The connector has a three-directional rotary degree of freedom but has not a vertical degree of freedom and a front and behind degree of freedom. The load of compacter 5 acts on the compacter 6. The paving material 11 fed to the compacter 5 drops from a feeder 13 and it is compacted by a leveling device 14 to form the lower bed 3 of pavement 2. The feeder conveys the paving material to the upper compacter 6 and the paving material is compacted on the lower bed by an upper bed leveling device 33 to form the upper bed. Both compacters 5, 6 are synchronously operated through the connector 7 and the upper and lower beds are continuously and securely compacted.

IPC: B21D9/00
Filed: 1986-10-29
Abstract: PURPOSE:To prevent the generation of a pollution by using a lead, etc., as the core material and to realize a labor saving by freezing a water with its filling up between an inner and outer pipes arranged on the same axial line and simultaneously curving the inner and outer pipes with the freezed ice as the core material. CONSTITUTION:The inner and outer pipes 2, 1 cut in an adequate length are first prepared for forming a curved multiple pipe. The inner pipe 2 is then inserted into the outer pipe 1 and after supporting the inner pipe 2 inside the outer pipe 1 so that the center line of the inner and outer pipes 2, 1 become on the same level a water is freezed with its filling up between the inner and outer pipes 2, 1 and it is taken as the core material. The inner and outer pipes 2, 1 are simultaneously curved by an adequate means together with the core material and after the formation the freezed ice is thawed and flowed out as water. Since a lead and melting alloy are not as the core material, the finishing work after forming can thus be saved in its labor and no pollution is caused as well.

Abstract: PURPOSE:To protect an excess deflection voltage and to prevent X-ray radiation by providing a logic circuit which sets a peak rectified voltage of a flyback pulse as a feedback voltage of a power supply circuit and outputting a prescribed feedback voltage when the peak rectified voltage is lower than a prescribed voltage. CONSTITUTION:A peak rectified voltage 15 of a flyback pulse 10 is fed back to a power supply circuit 5 when a high voltage power supply to a deflection circuit 1 rises abnormally to decrease its DC output voltage 6 thereby stopping the operation of the deflection circuit 1. Moreover, when the operation of the deflection circuit 1 is stopped, the peak rectified voltage 15 is decreased more than the prescribed voltage to decrease the DC output voltage 6 thereby preventing excess voltage from being applied to the deflection circuit 1. Thus, the deflection circuit 1 is prevented from an excessive voltage and X-ray radiation is avoided.
