Title: Speed control device for servomotor
Inventor: TANAKA TOSHINARI
IPC: G05B13/00
Filed: 1985-09-11
Abstract: PURPOSE:To make the titled control device correspond to any pulse encoder having a difference in the number of output pulses without generating the immeasurable operation of a servomotor in the stopped state even if a standard amplifier is used by constituting the control device of the servomotor, a pulse encoder, a counter, a D/A converter, an I/V conversion amplifier, a gain adjusting means, and a servo amplifier. CONSTITUTION:An operation voltage to be outputted to the servo amplifier 8 can be boosted by switching the bits of the counter 4 such that '0, 0, ..., 0, 0, 0', '0, 0, ..., 0, 0, 1', '0, 0, ..., 0, 1, 0', ..., are converted into '0, 0, ..., 0, 0, 0', '0, 0, ..., 0, 1, 0', '0, 0, ..., 1, 0, 0', .... Since the gain is adjusted digitally, the generation of an output voltage in the stopped state which may be caused by offset or drift can be suppressed and the immeasurable operation of the servomotor 1 in the stopped state is not generated even if a standard and inexpensive I/V conversion amplifier 6 is used. In spite of the inexpensive constitution, the control device can be efficiently operated even if a pulse encoder 12 having a difference in the number of output pulses is connected.

Title: Vibration controller
Inventor: TANAKA TOSHIMITSU
IPC: F16F15/02
Filed: 1991-08-12
Abstract: PURPOSE:To provide a vibration controller equipped with a function that is able to do self-compensation for the resonance frequency of this controller attending on a variation in ambient temperature. CONSTITUTION:A weight 8 is installed in each top of steel plates 3, 3 joined in a layer form in holding a viscoelastic body 2 between. This weight 8 is shiftably supported in space between the vicinity of a support part 5a in relation to a support block 5 and the free end side, and the weight 8 and the steel plate 3 are connected to each other through a form memory alloy 9. In this constitution, the weight 8 is shifted in a proper direction by a deforming action of the form memory alloy 9 with a variation in ambient temperature, and thereby a spring constant is varied to some extent. In keeping with this, the value of resonance frequency is varied as well. With a suchlike characteristic utilized, even in the case where the ambient temperature is changed, a fact that this value of the resonance frequency is kept almost in a constant value in substance is made realizable.

Filed: 1988-08-12
Abstract: PURPOSE:To add heavy metal in low concentration and to enhance the accuracy of controlling a lifetime by employing powder mixed with heavy metal element as a diffusion source. CONSTITUTION:2-500ppm of heavy metal such as iron by mass ratio is mixed in powder made of polycrystalline silicon particles having several tens mum of particle size to form powder 12. Suitable amount of the powder 12 is scattered to adhere to the surface of a silicon substrate 11, several hundreds-several thousands of substrates 11 are so brought into contact to be superposed as to interpose the powder 12 thereamong, and inserted in this state into a diffusing furnace held at 800-900 deg.C. After the insertion, it is heated at a predetermined rising rate, and heat treated at 1200-1300 deg.C for several hours-several tens hours. With the powder 12 as a diffusion source Fe mixed in the powder 12 is diffused in the substrate 11 by the heat treatment. Thus, since the absolute amount of lifetime killer to be introduced into the substrate 11 is limited, heavy metal concentration can be accurately controlled in a range of relatively low concentration.
