Title: Automatic gear for synchronizing phase of circuit
Inventor: ARAN BUURANJIYAA
IPC: H03L7/00
Filed: 1992-04-02
Abstract: PURPOSE: To converge phase synchronization in every state by providing a high speed loop correcting a transient disturbance and a low speed loop correcting a phase shift over a wide range so as to attain automatic preset and to obtain the phase synchronization over a wide frequency and in a short synchronization time even on the occurrence of a slow and monotonous phase disturbance. CONSTITUTION: An input signal Φe(ρ) is measured directly at an input of a channel to generate a desired signal level in a high speed loop. The signal is delayed at a delay line 5 by a delay time τ. The signal is phase-shifted by a low speed loop phase shifter 9 and a 0/180 deg. inverter 10. A variable delay line circuit VDL consisting of the delay line 5, the low speed loop phase shifter 9 and the 0/180 deg. inverter 10 configure a variable delay line. Finally the adjustment of delay to generate a desired value is attained by a circuit including the low speed loop phase shifter 9, the 0/180 deg. inverter 10, a low speed loop amplifier 12 and its detection and controller 13.

Title: Determination of standard position in loom and device therefor
Inventor: ABE NOBUYASU
IPC: G05B19/18
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To enable to easily and accurately specify a relative position relation between the rotation angle of an exclusive motor and the position of a driving target by a user, too. SOLUTION: When a detection arm 40 is controlled to a prescribed operation position which is expressed by the chain line position and at which the amount of terry is zero, a starting point-presetting switch 49 is switched on. By the switch-on operation, a control circuit 37 memorizes a grasped standard position- reflecting element from a rotary encoder 282 into a memory 36. When the starting point-returning switch 50 is switched on, the control circuit 37 operates a terry motion motor 28 at a considerably slower rate than a rotation rate on a weaving operation. After a proximity switch 41 is switched from ON into OFF, the control circuit 37 memorizes a rotation angle as a standard position into the memory 36, wherein the rotation angle is obtained, when the rotary encoder 282 outputs a first starting point pulse.

Abstract: PROBLEM TO BE SOLVED: To prevent damage of an inner race and a rolling element and improve baking with a rotary shaft by constituting at least the inner race and the rolling element of a touch- down bearing by high speed tool steel or aluminium chrome molybdenum steel for which a nitriding is performed. SOLUTION: Each touch-down bearing 17 is not damaged due to impact force and frictional heat because all of an inner race 31, an outer race 32 and a rolling element 33 are made of high speed tool steel and the hardness is high values even at high temperatures, even if a rotary shaft performing a high speed revolution touches down to each touch-down bearing 17 due to a revolution abnormality. All of the inner race 31, the outer race 32 and the rolling element 33 are made of the same material, do not attack each other and become further difficult to be damaged.  Because the rolling element 33 is constituted of a plurality of large opening rolling elements 33a which come into contact with the inner race 31 and the outer race 32 and a plurality of small opening rolling elements 33b which have smaller diameters than these rolling elements 33a and these rolling elements 33a, 33b are alternately arrayed in the circumferential direction, the small opening rolling elements 33b revolve in the directions opposite to the large opening rolling elements 33a on both of the neighboring sides, the large opening rolling elements 33a each other become easy to revolve in the same direction and damage of the bearing 17 can be more effectively prevented.

Title: Focus detector
Inventor: KUSAKA YOSUKE
IPC: G02B7/28
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To properly correct a defocusing amount with respect to a subject in which the spatial frequency of a low frequency region is more included than a spatial frequency to be used in a focus detection by finding spatial frequency distributions of optical images formed by a dividing optical system and correcting a defocusing amount, based on the distributions. SOLUTION: Luminous flux transmitting a photographing optical system is dividingly formed by a dividing optical system 1. The phase difference between divided optical images is detected in a phase difference detecting means 2 and a defocusing amount is calculated, based on the phase difference by a defocusing amount calculating means 3. Besides, a converting means 4 calculates spatial frequency distributions of the optical images. Then, a correcting means 5 corrects the defocusing amount so as to correspond to the spatial frequency distributions. Since a constitution optically correcting the deviation of the best image surface in a photographing optical system is not used in this detector in such a way, the defocusing amount is properly corrected according to the images of the subject with a simplified and small-sized optical system.

Filed: 1987-05-07
Abstract: PURPOSE:To prevent intrusion of cooling water into a combustion chamber by having a cooling water jacket provided around an exhaust expansion chamber communicated to the position on the exhaust lower stream side from an exhaust introduction part in an exhaust passage. CONSTITUTION:Cooling water having passed a water jacket 33 of an engine 12 passes in water jackets 50-53 and cools an exhaust box 35.

As the exhaust introduction part 54 is located upper than the communication part 55 in this way, drain can be prevented from being dragged or flown into the exhaust expansion chamber 45 or the engine 12 because of exhaust pressure wave, posture change of a boat body and so forth.
