Title: Transfer device of dredged sand
Inventor: KAWAKITA YOSHIMASA
IPC: E02F7/00
Filed: 1991-04-25
Abstract: PURPOSE:To eliminate the need to discharge the stored water of a dam when dredged sand is discharged from the dam to reduce the influence on downstream areas of the dam or on the production of electric power and water works, eliminate the provision of sand discharge gates or water sealing gates, water- tightness of which is difficult to maintain, make power source devices smaller, and smoothly transfer the dredged sand even over a steep slope. CONSTITUTION:An endless wire 12 is driven to circulate each sand transfer truck 3 between a loading yard (a) above a dam 6 and a sand discharge pool (b) below the dam so that sand containing water 1 (sand + water having specific gravity of 1.0-2.0) dredged from the dam is loaded onto a truck 3 having reached the yard (a). The sands 1 carried by the truck 3 having got into the pool is discharged therefrom to load only the discharged water (specific gravity is 1.0-1.1), from which the sand has been separated, into the truck. As a result, in the drive system of trucks 3, the weight of the trucks going down from the yard (a) to the pool (b) is transmitted to the trucks 3 of the whole circulation system through the wire 12, so that the trucks 3 are circulated along a forward and backward track 12.

Title: Device for managing number of visitor/leaver
Inventor: SAKAE KAZUO
IPC: G06M7/00
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a visitor/leaver number managing device for counting the number of visitors/leavers with high precision even when any temporary communication error is generated between a detecting unit which detects visitors/leavers and a managing unit which manages the number of visitors/leavers. SOLUTION: A detecting unit 10 counts the cumulative number of visitors/ leavers since start, and periodically outputs the number of visitors/leavers as detection data Xm and Ym by radio. A managing unit 11 receives the detection data Xm and Ym by radio, and updates and stores the data as new management data Xn and Yn. Therefore, the detecting unit 10 itself counts the cumulative number of visitors/leavers Xm and Ym, and transmits the data to the managing unit 11 so that even when errors are generated in radio communication several times in the management period, the correct cumulative number of visitors/ leavers Xm and Ym can be transmitted from the managing unit 11 to the detecting unit 10, and the number of visitors/leavers can be counted with high precision.

IPC: H01L21/027
Filed: 1980-07-15
Abstract: PURPOSE:To perform focusing accurately by projecting a focusing incident light on a photomask for a semiconductor obliquely, making circuit the reflected light to a straight sensor and shifting the mask according to the detecting position of the sensor. CONSTITUTION:A semiconductor mask 7 on a holding stage is irradiated by an illumination light and image-formed on a pattern detector 1 through a lens 20. A laser beam 14 is projected on the mask 7 obliquely through a semitransparent mirror 16 and forms a light spot 21 through a lens 20. The reflected light of the light spot 21 is imaged on the position corresponding to the defocusing on a straight sensor 30 through the semitransparent mirror 16 and a filter 31 and the output is sent to a deciding circuit 50. The semitransparent mirrors 16B and 16D reflect the illumination light transmitted through the mask, a detection sensor 34 detects only the illumination light transmitted through a filter 33 and a deciding circuit 35 corrects the darkness of a pattern. The output from said circuit shifts the mask 7 vertically through a driving system 36 and a motor 5. Thus, focusing can be performed accurately.

IPC: H03F1/02
Filed: 1979-07-27
Abstract: PURPOSE: To put an electric power circuit into high efficiency operation by changing over the electric power voltage of an electric power amplifying circuit on the basis of a signal that corresponds to an input signal and a signal obtained by peak-holding the signal, as to an audio electric power amplifier.  
     CONSTITUTION: Peak holding circuit 54 sends the output of comparator 46 with a fixed time constant and its hold signal is supplied to comparator 55. This comparator 55 compares the value of the hold signal to reference voltage EC 2  supplied from reference electric power source 56 and, only while the value of the hold signal exceeds voltage EC 2 , outputs a high potential and its output is supplied to the base of transistor TR50 by way of diode 57 constituting OR circuit 48. Then circuit 48, when either of outputs of comparator 46 and 55 is at a high potential, holds the base of TR50 at the high potential. Consequently, the electric power circuit is put into high efficiency operation by changing over the electric power voltage on the basis of a signal that corresponds to the input signal and a signal obtained by peak- holding the signal.

Filed: 1982-06-04
Abstract: PURPOSE:To enable to make fine adjustment to the angle of oscillatory rotation of a rotor shaft from the outside, by advancing and retracting an adjusting means formed with a tapered surface at its top through the wall of a cylinder. CONSTITUTION:When an adjusting means 10 is advanced, a drive pin 9 is turned reversely along a tapered surface 11, so that the angle is decreased. On the other hand, when the adjusting means 10 is retracted, the angle is increased.
