Abstract: PURPOSE:To deliver the supersonic vibration from a rotating member to the main body of the adaptor without attenuating substantially and permit to take it out as the detecting signal of an abnormal condition by forming a thin oil film between the rotating member and the main body of the adaptor which is supporting the rotating member. CONSTITUTION:The oil, supplied from an oil feeding port 4, is fed to the supporting part of the rotating tubular body 8 from a path 25 through one series of oil supplying paths 26-29 and the thin oil film 37 is formed at this part. Subsequently, a main spindle 42 is rotated to rotate the rotary tool 16 and a cutting work is effected. When an overload is applied to the rotary tool 16 under the working, a torque limiter 17 is operated and the supersonic vibration is generated by the detaching motion thereof. The supersonic vibration is also generated when the tool 16 is broken or abutted against other bodies. These supersonic vibrations are transmitted to the main body 1 of the adaptor from the rotating tubular body 8 through the oil film 37 without being attenuated substantially. The supersonic vibrations are detected by a supersonic wave sensor 33 and the abnormality of the rotary tool 16 is detected, therefore, optimum tool protection may be effected utilizing the detecting signals.

Title: Signal clamp system
Inventor: TAKADA HARUKI
IPC: H04N5/16
Filed: 1990-01-31
Abstract: PURPOSE:To sufficiently suppress fluctuation of an energy diffusion component even when the energy diffusion component superimposed on an incoming video signal is large by connecting a 1st clamp circuit and a 2nd clamp circuit in series. CONSTITUTION:A 1st clamp circuit 104 applies keyed-clamp a reference signal in an incoming video signal to a prescribed DC level for each horizontal synchronizing cycle and a 2nd clamp circuit 105 of a next stage feeds back a clamp level detected at a post stage of an A/D converter 106 to a clamp level of the 2nd clamp circuit 105. Then the reference signal is subject to keyed clamp for each horizontal synchronizing cycle so as to be a center value in an input range of the A/D converter 106. Thus, the energy diffusion component superimposed on an incoming video signal is suppressed to some degree by the 1st clamp circuit 104 and further suppressed by the 2nd clamp circuit 105 of the next stage. Thus, the energy diffusion component is sufficiently suppressed to keep the brightness of the reproduced pattern and its color tone stable and accurate thereby eliminating disturbance such as flicker.

Abstract: PURPOSE:To contrive the miniaturization of facilities such as an AC motor, a power board and the like and the reduction of power consumption by controlling the rotation of the AC motor with a given current during the temperature rising (descending) process of a work. CONSTITUTION:A cylindrical muffle 2 is arranged in a furnace body 1 while a cooling coil 5 and a heater 4 are arranged in the flow passage 3 of air, which is formed between the muffle 2 and the inner surface of the furnace body 1. A circulating fan 11, inducing air from the receiving space of a work W in the furnace body 1 and circulating it through the flow passage 3 of air, is controlled by a 3-phase AC motor 13. The load current I of the AC motor 13 is kept in constant during the temperature ascending (descending) process of the work W and, therefore, the motor 13 will never become overload even upon low temperature time, in which the density of air in the furnace body 1 is large, while the rotation of the circulating fan 11 can be driven by a necessary and sufficient minimum shaft power during heat treatment process. Accordingly, the AC motor 13 and a power board 14 can be miniaturized and a power consumption can be reduced. On the other hand, a current setter is provided in a current control circuit 22 and, therefore, operation, in which the load current I is low, can be effected within the allowable range of a heat treatment condition.
