Abstract: A controller inclines a movable body (WST) with respect to an XY plane at an angle a in a periodic direction of a grating 5 (39Y 1 , 39Y 2 ), based on a measurement value of an interferometer which measures an angle of inclination of the movable body to the XY plane, and based on a measurement value of an encoder system ( 62A, 62C) and information of angle a before and after the inclination, and computes an Abbe offset quantity of the 10 grating surface with respect to a reference surface (e. g., an image plane of a projection optical system) which serves as a reference for position control of the movable body in the XY plane. Then, the controller drives the movable body along the XY plane, based on positional information of the 15 movable body in the XY plane measured by the encoder system and a measurement error of the encoder system corresponding to an angle of inclination of the movable body to the XY plane due to the Abbe offset quantity of the grating surface.

Title: Method and device for determining detection range of control channel in multi-beam system
Inventor: TANG HAI
IPC: H04W24/02
Filed: 2017-03-23
Abstract: Method and Device for Determining Detection Range of Control Channel in Multi-beam System 5 The present application provides a method and device for determining a detection range for a control channel in a multi-beam system. The method includes: a network device sends configuration information to a terminal device, wherein the configuration information is used for the terminal device to determine a time domain resource in which control channel detection is required within a target downlink time period according to the configuration information, and 10 the time domain resource includes multiple time domain scheduling units. According to the method for determining the detection range for the control channel in the multi-beam system of the embodiment of the present application, the terminal device only needs to perform the detection of control channel on the time domain resource determined according to the configuration information, and those time domain resources (such as time domain scheduling 15 units where synchronization signals or broadcast signals of other beams are located) on which a control channel of a current beam is determined not to exist, may be excluded through the configuration information, so that the terminal device avoids detecting these part of time domain resources, thereby reducing the complexity and the battery power consumption of the terminal device. 20 FIG. 1

Abstract: 970,231. Machinery guards. SPERRY RAND CORPORATION. Jan. 1, 1963 [Jan. 9, 1962], No. 62/63. Heading F2J. [Also in Division B8] Obstruction of the guarded area (Fig. 1, not shown) of a conveyer results in a signal of decreased strength being transmitted by photoconductive cells PC1 and 2 (in series with NPN transistor stage T1) to parallel PNP transistor stages T2, T3. This results in the release of relays A and B. This releases a relay C by opening of contacts A2, B2 in circuit C4, C, B2, A2, S1, C2. Contacts C3 thus open to release a relay Cx which controls the conveyer (not shown). Contacts C1 isolate lamps LP1, LP2 which normally activate the cells PC1 and 2 respectively. To reset the system it is necessary to press push button PB and close switch KS. Failure of almost any component of the system will cause the system to " fail safe."

Abstract: 1,153,971. Glycidol; glycerol. FMC CORP. 9 Jan., 1967 [11 Jan., 1966], No. 1108/67. Heading C2C. Glycidol is produced by epoxidation of allyl alcohol in the absence of water at 25-100‹ C. using a 15-40% by wt. solution of peracetic acid in an inert solvent, the ratio of allyl alcohol to peracetic acid being 5À0-0À7 mols alcohol per mol acid, and continuing epoxidation until at least 70% by wt. of the minor reactant has reached to convert allyl alcohol to glycidol in a yield of at least 90%. The glycidol recovered from the reaction mixture may be hydrolysed to glycerol at 25-170‹ C. using 10-100 mols water per mol glycidol. Specified solvents for the epoxidation are lower ketones, esters, ethers and alcohols, alone or in admixture with halogenated alkanes. Epoxidation is preferably effected at 25-100‹ C. using excess allyl alcohol and rapidly and continuously removing solvent and by-product acetic acid by distillation under reduced pressure, e.g., below 400 mm. Hg, and recovering glycidol which can be further purified and will yield a pure glycerol on hydrolysis. The process is illustrated by reference to flow sheet and apparatus drawings (not shown).
