Title: Chucking method for thin plate and device
Inventor: ICHIKAWA KENICHI
IPC: B24B37/04
Filed: 1997-03-30
Abstract: PROBLEM TO BE SOLVED: To surely hold a thin plate work by intervening liquid between a chuck surface and the work and fixing the work to the chuck surface by its surface tension. SOLUTION: A flat chuck surface 2 of a chuck main body 1 is moisturized beforehand by liquid 3. The liquid 3 may be water, however, liquid having viscosity is preferable, for example, work liquid in polishing may be all right An appropriate method may be adopted for moisturizing with liquid and an ordinary method such as spraying, hand painting, or brush painting is applicable. A work 4 such as a thin plate semiconductor wafer is brought in contact with a chuck surface 2 moisturized with the liquid 3 so as to be closely held. This is because the surface tension of the liquid 3 acts on the thin plate work 4 so as to bring the work 4 in close contact with the chuck surface 2. A grinding wheel 5 is brought in contact with the work 4 held by the chuck 2 via the liquid 3 and the both of them are revolved and rotated so as to machine the surface of the work 4.

Title: Recording device
Inventor: SHIMIZU HARUO
IPC: H04N1/29
Filed: 1983-06-01
Abstract: PURPOSE:To accurately write picture information on a recording medium, by controlling the carrying timing of the carrying means of the recording medium so as to correct the writing starting point of recording information on the recording medium. CONSTITUTION:The on-timing of a register roller and off-timing of a paper feeding roller are changed by using signals 41a-41d from a regist adjusting switch 42. When the value of the switch is set to 0-6, the recording position is changed upward and the changing quantity is set in the way of 0<1<2-<6. Moreover, when the switch is set to 7 and 8, no changing quantity can be expected. When the switch value is 9-0 FH, the recording position is changed downward. When one cycle of a drum clock is set to T1 seconds, one step of the changing quantity is set to T1/8sec for convenience. When the switch value is 0-6, it is judged that the carrying speed of a recording paper is faster than the moving speed of a photosensitive body and the regist roller is wakened up. Then it is discriminated whether a time, (switch value +1)XT1/8sec, has passed or not, and, when it is judged that the time has passed, the paper feeding roller is turned off and, at the same time, the regist roller is driven. When such an arrangement is made, the carrying timing of the recording paper can be delayed against the movement of the photosensitive body.

Filed: 1980-07-17
Abstract: PURPOSE:To enable selection of one-minute timer or one-hour timer with a simple construction by counting the timer time with pulses fed to a time counting circuit in a cycle corresponding to a selected set range. CONSTITUTION:When a switch S3 is connected to a contact M, FF F2 is set through a differentiation circuit A4 and inputs a high level set output P1 into a gate circuit G2 and a D terminal of FF F1. With the application of a high level set output from FF F1, the output of the circuit G2 turns to a low level causing a gate G3 to open. Consequently, one-minute pulses from a divider D is applied to a counter C for which the time of a timer is set and the down counting thereof is started, constituting a one-hour timer. On the other hand, when the switch S3 is connected to a contact S, the down counting of the counter C with one-second pulses from the divider D, constituting a one-minute timer. This enables the selection of either one-minute timer or a one-hour timer.
