Title: Production of carburized and quenched gear
Inventor: KOBAYASHI MIKIKAZU
IPC: C25F3/24
Filed: 1990-11-14
Abstract: PURPOSE:To improve fatigue strength by applying shot peening to the dedendum part of a carburized and quenched gear and removing the rough surface by means of electropolishing.

Title: Manufacture of formed hose
Inventor: KURANAMI HIDEAKI
IPC: B32B1/08
Filed: 1990-11-16
Abstract: PURPOSE:To form approximately uniform roughness over the inner surface to avoid concentration of stresses by inserting a spring mandrel into an unvulcanized hose in which a resin layer, inner rubber layer, reinforcing string layer, and outer rubber layer are stacked from the innermost layer successively and withdrawing said mandrel after vulcanization. CONSTITUTION:Reinforcing strings constituting a reinforcing string layer 13 which have dry thermal contraction ratio of 0.5-5.0% at 150 deg.C and for 30 minutes are used so that an inner rubber layer 12 and a resin layer 11 bite into the outer periphery of a mandrel 15 during vulcanization. The spring mandrel 15 is inserted into an unvulcanized hose 10 cut to a predetermined length. Next, a rigid mandrel 16 is inserted into the mandrel 15 to form it into a specified shape and then vulcanization is effected. Since the layers 12, 11 bite into the outer periphery of the mandrel 15, approximately uniform roughness 17 is formed over the inner wall surface of the layer 11. Thereafter, if the mandrel 16 is pulled out and further the mandrel 15 is pulled, its outer diameter becomes smaller, so that it is easily pulled out.

Title: One-element type converter
Inventor: SHIMAMURA TAKASHI
IPC: H02M3/335
Filed: 1986-12-26
Abstract: PURPOSE:To compensate an input voltage range by maintaining the base current of a main transistor constant, thereby imparting an output constant voltage function to an RCC (ringing choke converter) circuit. CONSTITUTION:The output control circuit for an RCC has a voltage detector, and a control circuit. The control Tr Q2 of a main transistor (Tr) Q1 is controlled to be driven by the control circuit through a photocoupler light emitting unit PD from the voltage detector to supply a constant output voltage to a load. In this case, a diode D4 and a constant-voltage diode DZ2 are connected from the dividing point (b) of dividing resistors R6, R7 connected from the base of the main Tr Q1 to one end of a feedback winding NB through a diode D2 to the other end (c) of the feedback winding NB. Thus, a suitable set value does not substantially perform its function when the diode DZ2 is of 100 V system and so sets as to achieve its function when the system exceeds 100 V, thereby maintaining the base current of the Tr Q1 substantially constant.

Abstract: PURPOSE:To prevent a guide plate on which a sheet ejected from a fixing device abuts from being deformed by heat expansion, in a device, such as an electronic copying machine, which forms a recorded sheet by the use of a large- size sheet. CONSTITUTION:In the large-size electronic copying machine for a drawing, slits 16 are cut at prescribed intervals in the guide plate 15, particularly in the part which is heated by the sliding of a sheet, in a sheet carrying path arranged in the downstream part of a fixing device.

Filed: 1994-11-18
Abstract: PURPOSE: To hold the state of traveling normally at all times by directing the direction of the major axis of the through-hole of a guide runner in a slot rectangular in the travelling direction of the guide runner. CONSTITUTION: When a folding door 1 is opened and closed, the folding door 1 travels on travelling piece sections 32 by suspension by a suspension roller 30. On the other hand, travelling runners 14 are rotated smoothly as being brought into contact with the undersides 11a of projections 11 at the lower end of the folding door while the outer circumferential surface of a rolling outer ring 6 is brought into contact with one of the side wall 9 of a lower rail 3 and turned smoothly, thus lightly moving the folding door 1.  When the folding door 1 is inclined to one side and shaken, a vertical shaft 4 projected from the lower end of the folding door 1 and a guide roller 5 are also brought down together with the folding door 1, but the vertical shaft 4 can be tilted and moved crosswise regardless of a guide runner 12 because the vertical shaft 4 is inserted into the slot of the guide runner 12, and the travelling rollers 14 are revolved smoothly, thus resulting in no opening and closing of the folding door 1.
