IPC: C22C13/02
Filed: 1990-03-15
Abstract: PURPOSE:To provide the alloy for utensiles and ornaments which allows etching by incorporating Bi at a specific ratio into Sn to suppress the beta alpha transformation of the Sn. CONSTITUTION:The utensiles and ornaments are constituted of the alloy consisting of 1 to 10mass% Bi and the balance Sn. The cooling rate at the time of casting is preferably set low. The fine Bi is crystallized in a network state uniformly along the grain boundaries of the Sn alloy contg. 6 to 8% Bi in an etching treatment. The structure of this Sn-Bi alloy depends on a solidifying rate. The fine Bi grains disperse uniformly over the entire part of the structure in the case of rapid solification but the Bi grains crystallize at the grain boundaries in the case of slow solidification. The Sn-6% Bi alloy has about 20 Vickers hardness and the development of the products requiring strength is expected. Since Pb is not used, there is no harm on the human body.

Abstract: PURPOSE:To enable non-contact measurement only with light source bodies and a simple device on the light receiving section side, by arranging two light source bodies, a pair of light receiving sections, a position measuring section and the like. CONSTITUTION:A pair of right and left light source bodies 1 and 3 which emit luminous fluxes 2 and 4 alternately are provided on gears 15 and 16 respectively and because the gears 15 and 16 are meshed together, as one thereof turns, the other thereof does by the same angle in the opposite direction. On the other hand, the left light receiving section 9 has a highly light receiving sensitive directivity on the left side of the intersection 5 while the right light receiving section 10 does on the right side of the intersection 5. Therefore, when the reflecting surface coincides with the intersection 5 at the position 6, the left and right light receiving sections 9 and 10 detect the quantity of light of the same intensity. When the reflecting surface is at the position 7 and 8, that is, a approaches the light source side from the intersection 5 or moves further to the light receiving sections 9 and 10, dfferential signals of the respective light receiving sections 9 and 10 give AC signals synchroniz ing the alternate emissions of the light source bodies 1 and 3, being so provided that both of the signals are in opposite phase. A drive section 13 is driven depending on the differential signals. In this manner, even when the reflecting surface moves, the gears 15 and 16 turn forward or backward following the movement thereof and the angles of rotation of the gears 15 and 16 are detected with a position detecting mechanism 13 thereby enabling the measure ment of the position of the reflecting surface.

Inventor: KAGAWA NORIAKI
IPC: B25J17/02
Filed: 1991-03-29
Abstract: PURPOSE:To allow an operating tool to return to its initial position accurately by tilting an external force detecting member with respect to a pedestal when external impact acts on the operating tool, and thus absorbing the external impact, and making the receiving seat of the external force detecting member coincide with the inclined peripheral face of the pedestal when the cause of the external impact is removed. CONSTITUTION:When external impact acts on an operating tool, an external force detecting member 2 is tilted against a compression spring 9 with the contact point between its receiving seat 2a and a pedestal 1 serving as a fulcrum, and absorbs the external impact. Then a bolt 5 is oscillated because its end portion 5a is fixed to a spherical bearing 4; Accordingly, the end portion 5b of the bolt 5 is separated from a microswitch 10 and so the microswitch 10 is turned off and an industrial robot is stopped. Thereafter, when the cause of the external impact is removed, the external force detecting member 2 is returned to its initial position by the compression spring 9 and the receiving seat 2a coincides with the inclined peripheral face 1a of the pedestal 1. Therefore, the operating tool can be made to return to its initial position accurately and subsequent reproduced action can be achieved accurately.

Abstract: PURPOSE:To control control delay angle to optimum value without marring follow-up quick response of control current by reading current again and operating again when the control delay angle become direction of delay compared with previous time. CONSTITUTION:When current command As from a current command generating circuit 10 changed, for instance, from 25% to 200% stepwise, gate ignition is made for RS phase at time T3, and gate ignition is made for RT phase at time t4. Current value is read at time t5. However, as current is only 125% at this point of time, the phase does not become direction of delay remarkably. When operated control delay angle become delayed phase than control delay angle operated and outputted at time t4 by current feedback detected at time t5, current is read again at time tA is larger than current at time t5, gate ignition delays largely at time t6, and current is lessened sufficiently, and overshooting is suppressed. Thus, setting time of current can be quickened.

Abstract: PURPOSE:To back-diffuse a spread spectrum signal, and at the same time, to keep an actual data transmission speed high by generating a double frequency by frequency-mixing a spectrum, positioned symmetrically always for the former carrier frequency of a communication wave. CONSTITUTION:A frequency mixing means 11 frequency-mixes the spectrum, positioned symmetrically always for the former carrier frequency of the communication wave, and generates the double frequency.
