Title: Throttle valve controller for engine
Inventor: IIDA KATSUYOSHI
IPC: F02D43/00
Filed: 1984-10-11
Abstract: PURPOSE:To aim at improvements in responsiveness in suction quantity control and control accuracy ever so better, by installing an exhaust reflux quantity detecting device, which detects an exhaust reflux quantity, and a control constant changing device which changes a control constant in feedback control for a throttle valve. CONSTITUTION:Desired throttle valve opening theta1 or desired suction quantity Ac1 is found according to an accelerator operated variable alpha, and opening thetaR of a throttle valve is controlled for feedback so as to become this desired value. An exhaust reflux quantity detecting device 25 detects an exhaust reflux quantity to flow back to engine. There is provided with a control constant changing device 37 which receives output R of the exhaust reflux quantity detecting device 25 and makes a control constant K in feedback control for the throttle valve larger according to an increase in the exhaust reflux quantity. Thus, irrespective of the amount of exhaust reflux quantities, improvements in responsiveness in suction quantity control as well as in control accuracy are promoted.

Filed: 1981-12-26
Abstract: PURPOSE:To make controlling of image quality by biasing electric fields easy and to prolong the life of printing capacity by covering the surfaces of carrier materials for electrophotography with coating layers contg. conductive magnetic powder. CONSTITUTION:In carrier materials for electrophotography consisting of iron powder, ferromagnetic powder or glass beads, the surfaces thereof are covered with coating layers contg. conductive magnetic powder. With such constitution, first toners 1 receive electrostatic charge in the parts A consisting essentially of coating resins 3 where no islandlike conductive materials 2 exist. On the other hand, carriers 4 connected like a network contact with each other in a number  of conductive parts; therefore, the application of biasing electric fields is made possible, and the electric charge accumulating on the carriers 3 leak by passing through said routes. As such conductive media, the magnetic powder in a semiconductor region is most effective. If the conductivity is in a conductive region, the conductivity in the coating layers increases too much and the electrostatic charge of the toners is spoiled.

IPC: H01L21/322
Filed: 1991-08-28
Abstract: PURPOSE:To decrease crystal defects in the surface of an Si semiconductor substrate and sections in the vicinity of the surface by lowering the oxygen concentration of a section near the surface of the Si semiconductor substrate. CONSTITUTION:One main surface 2 changed into a mirror surface of an Si semiconductor substrate 1 is heated by a lamp by using a light source having a wavelength of 1-0.3mum under a vacuum, of 10<-6> Torr or less, and heated at 400-800 deg.C. Consequently, oxygen in the Si semiconductor substrate 1 is diffused outward at a low temperature because one main surface 2 is heated under the high vacuum. Since one main surface 2 is heated by the lamp within a range of the wavelength of 1-0.3mum, only a section near the surface can be heated, and a low oxygen-concentration region region 3 can be formed on the surface of the Si semiconductor substrate as shown in (b).
