Title: Toner image forming method
Inventor: SAITOU TAKASHI
IPC: G03G15/06
Filed: 1979-07-16
Abstract: PURPOSE: To prevent the deterioration and consumption of the developer and obtain good images by applying AC bias to a developer substrate at the time when the electrostatic image passes a developing part and holding the same in a potential state of preventing scattering of the developer at the auxiliary moving.  
     CONSTITUTION: At the developing since the time when the leading end of the electrostatic image formed on a photoreceptor by exposure of the original light image arrives at the developing part D until its trailing end finishes passing through the developing part D, AC bias is applied to a sleeve 12 but the application of the AC bias to the nondeveloping part where the electrostatic image to be passed is not passed through the developing part D even if the photoreceptor is rotating is stopped, and, for example, the DC bias voltage of the polarity opposite from the charging polarity of the toner is applied. These are accomplished by changing over a switch 19 to an AC bias power source 16 and a DC bias power source 17. Thereby, the deterioration of the one component developer may be prevented and the  good image may be obtained; in addition, the wasteful consumption of the developer is prevented.

Filed: 1979-07-20
Abstract: PURPOSE:To etch in high accuracy by a treating by automatically conveying and transferring  wafers over respective treating units, and measuring the size of a pattern on a wafer before and  after the etching to automatically control an adequate etching amount. CONSTITUTION:Wafers are supplied one by one from a supply unit 4 via a cartridge to an inspecting unit A. The wafers are partly sampled by a gate 9, are measured in size by a resist  mask size measuring instrument 6, and are controlled in the etching amount on the basis of the  result of the measurement by a controller H. The wafers not sampled are transferred through a  bypass passage to an etching unit B through a common outlet together with the inspected substrates. The etched wafers are also partly sampled and are measured in size by a size measuring  unit 6, and are then transferred to a pickup unit 5. After they are pretreated by a pretreating unit  11, they are plasma etched hy a plasma etching unit 12 in CF4+O2. When requiring other step  such as a step of forming a stopper layer thereon, the wafers are led in and out by a guide 13 to  be treated, are then plasma etched in O2, are removed with resist masks by a remover C, are then cleaned by a cleaner D, and are then contained one by one by a cartridge in a container 5. This  configuration can automatically etch in high accuracy and reduce the number working personnel concerned.

Filed: 1983-05-25
Abstract: PURPOSE:To make a user recognize the contents of an error and to shorten the error recovery time by blinking a display with difference given to the blinking time in case the error arrises to a device having just a single display. CONSTITUTION:When an error is produced, an error detecting circuit 3 controls an error code generating circuit 4 with an designation of a control part 1.

Abstract: PURPOSE:To improve an NOx purification ratio at an accelerating time. CONSTITUTION:A plurality of lean NOx catalysts 6a, 6b are parallelly arranged on an exhaust system 4, while sensors 10 and 14 are provided respectively for representing a catalyst floor temperature and detecting an operation condition under an accelerating time.

Filed: 1989-04-14
Abstract: PURPOSE:To eliminate gaps between a recess and a chipped electronic part by providing a carrier tape with recesses grooved in their side faces and resilient holding pieces for the reception of said part therebetween. CONSTITUTION:A pair of grooves 5 is provided in opposite lateral or longitudinal side faces of a recess 2. The groove 5 is given such shape that one side wall is vertical and the other is tapered inwardly of the recess 2. A holding piece 6 for a chipped electronic part 6 is extented toward the inside of the recess 2, since the groove 5 is tapered inwardly of the recess 2. The chipped electronic part 8 is retained gently yet accurely in the recess 2 due to a synergetic spring back effect which is produced by a slight bend 7 of a carrier tape 1 and the spreading out of the holding pieces 6 created when the tape 1 is received therebetween. By reason of the resiliency of these holding pieces 6 taking place in this way, gaps resulting from variations in the size of the chipped electronic part 8 and the recess 2 can be eliminated.
