Title: Shutter device for waste toner
Inventor: TAMEHIRA MASATO
IPC: G03G21/10
Filed: 1990-10-31
Abstract: PURPOSE:To make it easy to replace a waste toner bottle and prevent contamination by the waste toner during the replacement by providing a cam-shaped shutter which is to be coaxially attached to a conveyor screw and a driving means which opens and closes a discharge opening. CONSTITUTION:When a waste toner bottle 18 is stored in a case unit 12 the shutter 15 of a photoconductor unit 11 rotates an actuator 19 via the side face of the bottle 18 and pushes up a shutter arm 17 to open a waste toner discharge opening 13 and then the waste toner is conveyed by a screw 14 and discharged from the opening 13 and accumulated in the bottle 18. Next a door 21 is opened together with the bottle 18 and then the shutter 15 closes the opening 13 by means of a spring 16. As a result, the bottle 18 can be taken out of the unit 12 and replaced by a new one with both an upper frame and a middle frame or only the middle frame being integrated with a lower frame. In this case the waste toner is prevented from scattering because the opening 13 is closed. Similarly, the opening 13 is closed by the force of the spring 16 even with the middle frame being opened and so the waste toner is prevented from scattering during the replacement of the bottle 18.

Title: Electrostatic induction type semiconductor device and manufacturing method therefor
Inventor: SHIMIZU NAOHIRO
IPC: H01L29/06
Filed: 1999-10-18
Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic induction type semiconductor device for stable operation by enlarging a depletion ring layer as far as the lower side of a field limiting ring at turn-off to improve forward breakdown strength. SOLUTION: After p+ type regions 12 and 13 are formed at a silicon substrate 11, an epitaxial growth layer 14 of n+ type is formed. At a position corresponding to a guard region and a field-limiting ring, recessed parts 15A and 15B which are narrow and equal to each other in cross-section shape are so formed by wet-etching as to reach the silicon substrate 11 from the surface of the epitaxial growth layer 14. Since the epitaxial growth layer 14 remaining above a p+ type field limiting 20 specified by the recessed part 15B is separated from the silicon substrate 11, a depletion layer 30 expands beyond the field-limiting ring to assure a high forward breakdown strength.

Title: Method for molding resin coated slide part
Inventor: NOMIZO FUMIO
IPC: B29L31/16
Filed: 1991-10-16
Abstract: PURPOSE:To easily mold a slide part provided with a resin coating layer having excellent properties.
