Title: Surveying method
Inventor: SOEDA SHOSUKE
IPC: G01C15/00
Filed: 1992-02-25
Abstract: PURPOSE:To find the height of a target point and the distances in straight lines to the target point from two control points by measuring the distances from the two control points to the target point and inclination, azimuth, and distance between the control points. CONSTITUTION:The control point An of the current survey point, target point Pm, and the next control point Ab are set. Then the inclination nm and azimuth Qnm from the point An to the point Pm, inclination bm and azimuth Qbm from the point Ab to the point Pm, and inclination bn and azimuth Qbn between the points Ab and An are measured. The angles of the horizontal mapping nbm of the points An, Ab, and Pm become Rn=¦Qbn-Qbn¦, Rb= ¦Qnm-Qbn+180¦, and Rm=¦Qbm-Qnm¦. Since Dbm/sinRn=Dnm/sinRb=Dnb/sinRm from the sine theorem, the horizontal distance of the horizontal mapping nbm becomes Dnm= Dnb (sinRb/sinRm) and Dbm=Dnb(sinRn/sinRm). The height of the control point Ab becomes Hdm=Dnb (sinRn/sinRm) tanalphabm and the height of the other control point becomes Hnb=Lnb.sinalphabn. The distances in straight lines between the control points An and Ab to the target point Pm become Lnm=Dnm.secalphanm and Lbm=Dbm. secalphabm. Such calculation is executed with a computer.

Abstract: PURPOSE:To form an image in an enlarging mode even in the case of exceeding the limit voltage value of an exposing lamp and to improve safety and economicity by releasing limitation by a voltage limiting means at the time of forming an enlarged image under a set condition inputted from an operating means. CONSTITUTION:A CPU 202 always monitors the voltage V of the exposing lamp 102 and judges whether or not a copying mode in a copying machine is the enlarging mode, so that indication that the voltage of the lamp is over is lighted in the indication means of an operating and indicating part 201. Furthermore, the CPU 202 judges whether or not relation between the voltage V of the exposing lamp 102 and set voltage V6 in a RAM 204 is V>=Vb. When the relation shows V=Vb and V>Vb, a lamp power source 205 is cut off so as to turn off the voltage for the exposing lamp 102. The voltage of the exposing lamp 102 is always limited to be equal to or less than the set voltage Vb.

Title: Gas flow rate measuring instrument
Inventor: MORI YUKIO
IPC: G01F1/28
Filed: 1986-03-31
Abstract: PURPOSE:To secure constant measurement accuracy regardless of a change in flow rate state by making the pressure reception area of a moving member irrelevantly to the flow rate of gas to be measured. CONSTITUTION:An air damper chamber 10 is ventilated through only the clearance part between the external cylinder 3b of a moving member 3 and a large- diameter cylinder part 1b2 set fixedly to a housing 1b. Consequently, vibrations of the moving member 3 due to the pulsation of an air flow are suppressed and the variation of the moving member 3 is stabilized against stepwise variation in air flow rate, so that the behavior of the moving member 3 such as an excessive overshoot is suppressed. The moving member 3, therefore, moves linearly in parallel to the flow air in an air flow passage 2, so the pressure reception area of the moving member 3 does not vary even if the flow rate varies, and the constant measurement accuracy is obtained regardless of a change in flow rate state.
