Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to smoothly rotate a monitoring camera regardless of any increase in the amount of load by reducing the number of revolutions of a stepping motor if the load torque exerted on the stepping motor exceeds the output torque of the stepping motor. SOLUTION: The drive of a stepping motor 40 drives a bevel gear 42 via a rotary shaft 41, and a bevel gear 44 engaged with the bevel gear 42. It thereby rotates a rotary shaft 43, and a monitoring camera 1 mounted on a camera mounting section 45 on the rotary shaft 43. When the stepping motor 40 is initially set to 'an output torque T1 at a drive speed N1', and if the load torque exerted on the stepping motor 40 is T2, then, it is larger than the output torque T1 of the stepping motor; therefore, the stepping motor 40 is incapable of being accelerated and brought out of step. In this case a signal compare section 48 outputs a speed change signal to reduce speed to a value lower than the drive speed N2 to a drive signal generate section 49.

IPC: F16H25/12
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a smaller converter which converts rotational motion to liner reciprocating motion without mechanism composed of screws and nuts. SOLUTION: In a direct driven type converter 1, three balls 6-1, 6-2, 6-3 which are fixed in the positions with concentrically equal angle by a ball retainer 8 are sandwiched between a ball rolling surface 4a formed on a fixed annular plate 4 and a ball pressed surface 3a formed on the end of a direct driven shaft 3, and this condition is kept by a coil spring 9. The ball retainer 8 rotates synchronously with a rotating input shaft 2. Because three recessed and projecting cam surfaces are circumferencially formed on the ball rolling surface 4a, when the ball 6 retained on the ball retainer revolves with the rotating input shaft 2, the direct driven shaft 3 is reciprocated along the shaft line(L) due to reciprocating motion of each ball along the shaft line L.  Thus, a smaller direct driven converter having fewer dead zone is provided comparing with a converter composed of screws and nuts.

Title: Hot rolling method for copper-nickel alloy
Inventor: SAKAMOTO TOSHIMASA
IPC: B21B3/00
Filed: 1986-10-29
Abstract: PURPOSE:To prevent the intercrystalline cracking and internal cracking in the surface layer part of an ingot by rolling a rolled stock at a prescribed number of passes at specific thickness reduction ratios, then subjecting the stock to high-draft rolling in which the depth of the compressive stress region to be acted in the rolling direction is set at specific % or above of the sheet thickness. CONSTITUTION:The rolled stock which is a thick plate consisting of a copper-Ni alloy is first subjected to 3-10 passes of rolling at the thickness reduction ratio per pass set at 1-5% at the time of hot rolling said stock. The stock is thereafter subjected to >=4 passes of high-draft rolling in which the depth hc of the compressive stress to be acted on the rolled stock in the rolling direction thereof is >=85% of the thickness h0. Since the initial draft and the number of passes of the rolling are limited, the recrystallized grains in the surface layer part are formed and the intercrystalline cracking is prevented. The compressive stress region and the number of passes of the rolling are limited in the ensuing high-draft rolling and, therefore, the internal cracking is satisfactorily prevented. The generation of the intercrystalline cracking and internal cracking in the surface layer part of the ingot are thereby prevented.
