Title: Distance measuring equipment
Inventor: TAKADA SEIJI
IPC: G01C3/06
Filed: 1990-01-22
Abstract: PURPOSE:To prevent a range from being mismeasured owing to the start characteristics of a light emitting element by providing a control means which makes the output signal of a light receiving element ineffective when the number of times of projection of distance measuring light is less than a constant value. CONSTITUTION:When LEDs 3a - 3c are actuated, their light emission outputs are smaller than those in their stationary light emission states, so distance measurement data obtained by 1st and 2nd light emitting operations are processed as ineffective data and distance measurement data obtained by 3rd and succeeding light emitting operations are utilized to determine a gain. Namely, when the number of times of pulse light emission by a projecting element 2 is less than the constant value, the output signal of the light receiving element 7 is ignored. Consequently, accurate distance measuring operation can be performed without being affected by variation in the quantity of light due to the light emission characteristics at the time of actuating the projecting element 2.

Inventor: TANAKA TSUTOMU
IPC: F16D7/02
Filed: 1994-02-04
Abstract: PURPOSE:To provide a bearing device enabling generation of stable resistance torque while reducing the number of parts. CONSTITUTION:A plate spring 14 is inserted in the holding groove 22 of a bearing holder 12 from tip open parts 14A. A shaft 32 is then inserted through, and a small diameter part 34 is journalled into shaft holes 28, 30. The circular arc parts 14B of the plate spring 14 thereby come in surface contact with the outer peripheral surface of the small diameter part 34 of the shaft 32 so as to hold the shaft 32 in the state of being wrapped in from both sides. The circular arc parts 14B are pressed by ribs 52. Since the plate spring 14 is thus pressed always by the wall surface of the holding groove 22, frictional force to the shaft 32 is constant, so that resistance torque is stabilized.

IPC: H01L21/205
Filed: 1990-01-23
Abstract: PURPOSE:To accurately control impurities doping by a method wherein undoped compound is vapor-grown, impurity gas is supplied in the state that growth is interrupted, and doping process is repeated until the surface density of carrier is nearly saturated. CONSTITUTION:Undoped compound is vapor-grown on a substrate 1, and an undoped compound semiconductor layer 12A having a specified thickness is formed. Next, in the state that the growth is interrupted, impurity material gas is supplied to the layer 12A, and doping is performed until the carrier surface density is nearly saturated, thereby forming an impurities doped layer 12B. By repeating this process several times, a compound semiconductor layer 12 is formed. Althorough, in this method, the impurity concentrations of all of the compound semiconductor layers take discrete values, each of the values is uniform, and uniform concentration can be realized all over the region of a wafer independently of wafer position. Hence impurities doping can be accurately controlled, and a device having specified characteristics can be surely obtained with superior reproducibility.

Abstract: PURPOSE:To accurately effect oil feed indication and control by operating an oil feed indicator and an oil transfer means successively according to the liquid level signal from a liquid level detecting means. CONSTITUTION:When a first oil feed tank 9 becomes empty and the oil surface in a first oil receiving pan 8 becomes lower than a predetermined liquid level, a control device 26 actuates an oil feed indicator 24 to show that the first oil feed tank 9 has been emptied. When the oil surface in the first oil receiving pan 8 is further lowered to become lower than a predetermined liquid level L1, the control device 26 actuates an oil transfer means, i.e., an oil feed pump 15, to transfer the oil from a second oil receiving pan 10 into the first oil receiving pan 8. As a result of this oil transfer, when the oil surface in the first oil receiving pan 8 becomes higher than a predetermined liquid level L2, the operation of the oil feed pump 15 is stopped. When the first oil feed tank 9 is supplied with oil and the oil surface in the first oil receiving pan 8 exceeds a predetermined liquid level L3 higher than the predetermined liquid level L2, the operation of the oil feed indicator 24 is stopped. By the aforesaid operations, the oil feed indication and control can be accurately effected.
