Abstract: PURPOSE:To hold the self-absorptivity not causing displacement and flying of a work material even at the time of reducing the absorption force by a positive suction port and positive adsorption port provided in the holding body structure of a rotating table and a sub-suction port and sub-adsorption port opened on the table outer circumferential side surface. CONSTITUTION:A positive suction port 3 provided in a body structure rotatably holding a rotating table 6 of a rotary vacuum chuck, a sub-suction port 7 opened on the outer circumferential side surface of the table 6, a positive adsorption port 4 connected to the positive suction port 4, and a sub-adsorption port connected to the sub-suction port 7 are provided. The adsorption force of the sub- adsorption port 8 is small until the table 6 is reached to a determined rotation number from the stopping state, and during this period, it is necessary to adsorb a work material 5 by the positive adsorption port 4, but when the table 6 is reached to the determined rotation number, the adsorption force of the sub- adsorption port 8 is increased. At a result, even if the adsorption force of the positive adsorption port 4 would be reduced by various causes during rotating the table 6 at a higher speed than the determined rotation number, the disposition and flying of the work material by centrifugal force are never caused.

Title: Variable focus liquid crystal lens
Inventor: SATO SUSUMU
IPC: G02B3/10
Filed: 1984-12-11
Abstract: PURPOSE:To improve the orientation characteristic of liquid crystal molecules and the transmission characteristic of a liquid crystal lens by orienting concentrically or radially the liquid crystal molecules of a liquid crystal cell made into the shape of a lens. CONSTITUTION:The liquid crystal molecules are central-symmetrically oriented along a curved wall surface if the liquid crystal molecules are oriented in the concentrical direction. The local unevenness of the orientation is therefore eliminated and the molecular orientation state uniform over the entire region of the liquid crystal cell is obtd. On the other hand, the similar state is obtd. even if the liquid crystal molecules are radially oriented from the central part toward the peripheral part of the cell. The cell acts as a lens of the focus variable with the light polarized in all directions and there is no need for a polarizing plate. There is similarly no need for the polarizing plate with the construction in which the liquid crystal cell 9 having the concentrical orientation characteristic and the liquid crystal cell 10 having the radial orientation characteristic are superposed. The variable focus lens having the uniform molecular orientation characteristic is constituted in the above-mentioned manner and since the bright lens is thereby obtd., the lens is usable as an ordinary spectacle lens.

Abstract: PURPOSE:To identify accurately whether the aspect ratio is 16:9 or 4:3, that is, the picture is a wide picture or a usual picture by calculating a threshold level based on a period of a reproduced control signal. CONSTITUTION:A counter circuit 13 counts a leading of a reproduced control signal from a wide picture identification circuit 12 as a clock signal and compares the count with a count N1 or N2 set in advance. For example, let the count N1 be '5' and the count N2 be '2', a desired code pattern representing a wide picture is compared with 4-bit data stored in a 4th memory 11. When the data are coincident five times, the count is set to '5', the circuit 13 outputs '1' to discriminate it that a wide picture is recorded. Furthermore, when the count is '2' or below, the circuit 13 outputs '0' to discriminate it that a usual picture is recorded. The operation above is implemented for the reproduction period to identify the picture accurately.
