Title: Forging billet for piston of engine
Inventor: KOIKE TOSHIKATSU
IPC: B21K1/18
Filed: 1994-10-20
Abstract: PURPOSE: To obtain a forging billet which prevents flaws and cracks in forging by forming the outer circumference of a piston pin boss part through that of a center skirt part with a curved surface having a curvature larger than the minimum thickness. CONSTITUTION: The inner circumference 2 of a piston billet is formed in the shape of nearly complete roundness, and its outer circumference 3 is formed in an elliptic shape close to complete roundness, making the side of a piston pin boss part 10 a minor axis. A forging billet 1 is formed such that the cutting width (b) of the outer circumference, in the center of a skirt 11 in the direction vertical to a surface running through the center of both piston pin boss parts 10, is made larger than the finishing allowance (a) of the outer circumference in the piston pin boss part 10, and that the outer circumference of the piston pin boss part 10 through that of the center part of the skirt 11 is formed with a curved surface having a curvature larger than the minimum thickness (c).  Thus, at the time of forging, thickness is extruded to the tip end at the projected part without causing underfill, the elongation of the material is eliminated at the recessed part and cracking is prevented.

Title: Inductive load driving circuit
Inventor: KIKUYAMA SEIICHIRO
IPC: H02P7/288
Filed: 1986-11-25
Abstract: PURPOSE:To alleviate the current capacity of a discharge diode by connecting the diode between the output terminal of a transistor connected to a high potential point of transistors connected in a bridge and a control electrode. CONSTITUTION:When transistors 3, 6 are conducted, a current flows from a high potential power terminal 1 through the transistors 3, 6 and an inductive load 11 to a low potential power terminal 2. When the transistor 6 is interrupted in this state, the output potential of a connecting point B rises due to a counterelectromotive force generated at the load 11. At this time, a current is supplied through a discharge diode 15 to the base of a transistor 5, which is reversely operated. Thus, the energy stored in the load 11 is discharged. In this case, the current flowing to the load 11 is the base current of the transistor 5, and the current capacity of the diode 15 can be reduced.

Filed: 1990-10-22
Abstract: PURPOSE:To prevent the generation of heat due to disposition arrangement of many clad wires by providing an electrically conductive metal foil within a synthetic-resin substrate with this metal foil being in contact with the clad wire, and drawing end portions of each metal foil to the outside of the substrate. CONSTITUTION:Conductive corrugated metal foils 6 such as those made of aluminium, copper or the like are embedded within a synthetic-resin substrate 2 in a state wherein the foils 6 are contacted with insulation cladding 4a of their corresponding clad wires 4, and front and rear end portions 6a, 6a of each metal foil 6 are drawn outside. Accordingly, the heat generated in the clad wire 4 is transferred to the metal foil 6 to be dissipated from an opening 15 after passing through an air groove 6b. Further, the high frequency noises generated from a connector 16 are absorbed into the metal foil 6 by the action of a capacitor formed by the insulation cladding 4a of the clad wire 4 and the metal foil 6, and are grounded via grounding pressure-contacted terminals 3'. Consequently, the heat of each clad wire 4 is dissipated. This enables increase in density of the wiring by arranging a number of the clad wires 4.

IPC: E04H6/18
Filed: 1990-10-19
Abstract: PURPOSE:To ensure high efficiency for automatic parking on a plane by applying the constitution where a pallet is loaded and unloaded via an automated single pushbutton operation according to electrical control, while adding a taper guide support fitting or a positioner for a pallet expansion line loading roller guide. CONSTITUTION:When a pallet begins to travel along the lower side of a pallet support 3 on the operation of an unloading stacker, a fork support section 9 stops, superposed immediately on the lower side of the pallet support 3 at a selected instruction position, under microcomputer control. The stacker, then, arrives at a terminal floor 18, and gives a primary stop due to the detection of a fork support pallet. Thereafter, the fork descends to the lowest limit to release the pallet, and the stacker slightly retreats and re-advances for correcting the fixed point of a cycle start. Then, the stacker finishes a stop at the start fixed point via a secondary stop due to stacker detection, thereby ending a cycle operation. Parking on or leaving from the pallet is undertaken by a driver, and the stacker rises according to a pushbutton instruction, regarding the loading of a re-parking pallet, the return of an empty pallet or the like.
