Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To prevent the image density of a toner image developed on a photoreceptor drum from being unstable by the increase of an additive concentration or the unevenness of a heaped toner quantity, in a toner housing part. SOLUTION: In developing an electrostatic latent image formed on the photoreceptor drum 14, a screw feeder 34 carries the toner in the vicinity of a position facing a toner supplying port to the vicinity of the position facing a toner recovering port 24, in the toner housing part 8, by the rotation in the direction of the arrow A of a stirring plate 9.

Title: Manufacturing apparatus for semiconductor device
Inventor: TEZUKA TATSURO
IPC: H01L21/027
Filed: 1990-10-01
Abstract: PURPOSE:To enable reduction of the amount of wastes in a chemical liquid by a method wherein a constituting a diaphragm which partitions the primary side space around a filter filled with a supplied chemical liquid from the secondary side space toward the discharge pipe filled with the chemical liquid through the filter is partly constituted of an elastic plate. CONSTITUTION:A diaphragm which partitions the primary side space around a filter 1 filled with a supplied liquid 5 from the secondary side space toward a discharge pipe 4 filled with the chemical liquid 5 passing through the filter 1 is partly constituted of an elastic plate 6. Therefore, upon pressurization of the chemical liquid 5 by a pump 8, the synthetic rubber plate 6 constituting the diaphragm is pushed to the secondary side, while the chemical liquid 5 is dripped down on a semiconductor substrate 10; when dripping ends, the pump 8 shrinks with the result that this plate 6 recovers the original state because of a decrease in the primary side pressure. At this time, the secondary side pressure increases as compared with dripping of chemical liquid so that droop is prevented. This process dispenses with installation of a suck valve and the like on and after a filter housing 2, thereby reducing the amount of wastes in a chemical liquid.

Abstract: PURPOSE:To suppress the change in the projection of a head due to the quantity of the amplitude of an arm member by forming an arm mount member with a shaft supporting the arm member to an arm support member in a rocking way. CONSTITUTION:The arm mount member 4 is formed by a shaft supporting the arm member 3 in a rocking enable way to the arm support member 5. That is, one end of the arm member 3 is supported in a rocking way by the shaft in place of fixing it to the arm support member 5 with a screw as the arm mount member 4. Thus, when the arm member 3 is driven by an arm drive mechanism 7, one end of the arm member fixed to the arm support member by a screw is bent, the head is not displaced toward the rotary shaft of the rotary drum, but the shaft as the arm mount member 4 does not bend one end of the arm member 3 but rocks to displace the head 2 mounted to the other end of the arm member 3 in the axial direction of the rotary drum 6. Thus, the projected change (degree of projection) of the magnetic head 2 with respect to the amplitude change of the arm member 3 is reduced.
