Abstract: PURPOSE: To prevent a large amount of storm water from flowing into sewerage through a street inlet, in a heavy rainfall. CONSTITUTION: One end of an imperfect-valve support 4 is swingably mounted in the vicinity of an outlet 21 for fluid and an imperfect valve 5 closing the outlet 21 partially and not closing the outlet 21 perfectly is provided on the other end of the imperfect-valve support 4. The imperfect valve 5 can be reciprocated between an imperfectly closing position partially closing the outlet 21 therewith and an opening position being apart from the outlet 21, by the swing of the imperfect-valve support 4, and a float 42 is provided on the imperfect- valve support 4.

Abstract: PURPOSE:To stabilize contact and reduce the contact resistance by a method wherein a polycrystalline Si film doped with high-concentration arsenic is connected to an electrode metal film mainly made of aluminum via high melting point metal silicide film and barrier metal film. CONSTITUTION:An As buried layer 2, an epitaxial grown layer 3, and an insulation oxide film 4 are formed on an Si substrate 1, and a collector phosphorus diffused layer 5, a base region 6, and an emitter base isolation oxide film 4' are formed. Polycrystalline Si films 8 are selectively formed, and As is ion- impoanted. A CVD oxide film 8 is formed and heat-treated, thus forming an emitter region 9. A Pt silicide film 10, a Ti-W film 11, an Al film 12 are formed by opening the CVD film. Since the high melting point metal silicide film is in contact with the N type polycrystalline Si film 7 doped with 10<19> atoms/cm<3> or more of As atoms, the contact resistance can be reduced to an extreme degree without generation of abnormality.

Filed: 1994-09-01
Abstract: PURPOSE: To control the variation range of a screen grid voltage with high precision. CONSTITUTION: A D/A converter 201 receives a digital control signal VBUS and generates an analog signal VOUT. The signal VOUT and a high voltage U are coupled with a screen grid voltage VS-generating circuit 200 through resistances R2 and R1. A couple of transistors Q2 and Q3 form a differential amplifier. The base voltage of the transistor Q2 is set to a nearly intermediate point of the signal VOUT, and the screen grid voltage VS is generated at the connection terminal 200a of resistances R1 and R8. The resistances R1, R8, and R2 determine a minimum value that the voltage VS can possibly have and this minimum value is generated, when the signal VOUT is 5 V, i.e., at the upper limit of the voltage variation range.

Abstract: PURPOSE:To execute an automatically power source turning-off function in matching the real status of setting time by controlling such a way that the automatically power source turning-off function is not executed when there is an operator using a copying machine within a prescribed range of the periphery of a copying machine in the set time. CONSTITUTION:Based on in-room persons information transmitted from incoming and outgoing persons control system 50, the copying machine A controls the automatically power source turning-off function according to the presence or absence of persons in the room. If there are persons in the set time in a room 1 where the machine is installed, an operator is in the room 1, that is, within a prescribed range of the periphery of the machine, and does not execute the automatically power source turning-off function so that persons there can use the copying machine A. On the other hand, if there is no person in the room, the power source is automatically turned off as the time has been set. In such a manner, the incoming / outgoing person control system 50 acts as a means detecting the presence or absence of an operator in the room where the machine is installed.

Filed: 1987-09-29
Abstract: PURPOSE:To prevent the damage of the bearing in the caption due to the abnormal abrasion of a bearing pad by providing the back face side corner part of the bearing part with a protruding part being adjacent to a bracket metal and a tap bolt, at the same level as the protruding position of a pivot. CONSTITUTION:A gap S is provided between a bearing pad 8, a bracket metal 5 and a bolt, while the protruding part 9 of the same height as a spherical pivot 3 on the back face side corner part of the bearing pad 8, and the contact point C of the protruding part 9 with the bracket metal 5 and the contact point D of the protruding part 9 with a tap bolt 5 are allowed to have the same height as that of the contact point P of the spherical pivot 3 with the bracket metal 5. In this constitution, although the inclination of a thrust collar 2 during operation causes the bearing pad 8 to be displaced due to the movement of the protruding part 9 to a point C' from the point C, the bearing pad 8 will not cause abnormal abrasion due to the absence of the outwardly pressing force of the protruding part 9 occurring on the outside flange 5a of the bracket metal 5.
