Title: Particulate meter
Inventor: TSUBOUCHI KAZUO
IPC: G01N15/14
Filed: 1990-04-25
Abstract: PURPOSE:To decrease the amount of leaking and to obtain the highly accurately measured result by sealing the connecting parts of an optical cell in a double or more patterns, and forming minute spaces. CONSTITUTION:An optical cell 6 is formed of quartz glass. A flow path part (a) is formed of the optical cell 6, an introducing part 16 and a discharging part 18. The cell 6 is supported with the introducing part 16 and the discharging part 18 under the state wherein the cell is pushed from both ends. 0 rings 34, 36, 38 and 40 are crushed. Thus, the connecting part between the cell 6 and the introducing part 16 and the connecting part between the cell 6 and the discharging part 18 are sealed in a double pattern. When the 0 rings 34 - 40 are crushed, intermediate space parts 42 and 44 are formed in ring shapes. The pressure in the intermediate space parts 42 and 44 is reduced to the specified pressure or lower by way of intake and discharging holes 42A and 44B of an intake and discharging system 30. In this way, the pressure-reduced intermediate space parts 42 and 44 are separated from the low-pressure gas with the 0 rings 36 and 40 when the low-pressure gas to be measured is introduced through the introducing part 16 and discharged through the discharging part 18. The space parts 42 and 44 are separated from atmosphere with the 0 rings 34 and 38. Therefore, the leakage of the low-pressure gas is decreased, and the particulate can be measured highly accurately.

Abstract: PURPOSE:To convert the access time to a high speed by utilizing a hologram element for an optical disk device, making an optical head small in size, and also loading the small-sized head on a floating mechanism. CONSTITUTION:Light emitted from an optical head 10 constituted by forming as one body a laser diode 1, a hologram lens 2 and a photodetector 3 and containing them in a holder 4 is focused to a recording layer 8a on a disk 8, and in a reflected light from the disk 8, only light which transmits through the hologram lens as a zero-order light is photodetected by the two-split detector 3, by which a track error signal and a reproducing information signal are obtained. Also, when the disk 8 is at a standstill, the optical had 10 is pressed in the direction of the disk 8 by an action of a spring 13 of a floating mechanism 11, and when the disk 8 is turning, the head is floated onto the disk by buoyance generated by a head slider 12. Therefore, the mechanism is simplified by making a focusing mechanism unnecessary, and tracking is executed by loading the head on a tracking actuator 15.
