Abstract: A pallet exchange apparatus has a bed and an arm assembly supported on the bed to be rotatable between a workpiece loading-and-unloading station and workpiece machining station. A pair of cylindrical holes are formed at both ends of the arm assembly for receiving the pallets. The apparatus is further provided with driving means for rotating the arm assembly, a turntable rotatably mounted on the bed at a position corresponding to the workpiece machining station, first engagement portions formed at the ends of the arm assembly, second engagement portions formed on the pallets so as to be engaged with the first engagement portions for preventing the rotation of the pallets, and a moving device disposed on the turntable for moving the pallet located at the workpiece machining station in the vertical direction. When the pallet is lowered by the moving device, the pallet is separated from the turntable and the second engagement portion of the pallet is engaged with the first engagement portion.

Abstract: A clamping device which holds a workpiece at a predetermined position during a machining operation of the workpiece comprises a clamper for clamping a workpiece, a feed device for moving the clamper in the axial direction, a load sensor which is fixed to the clamper and detects a clamping force acting on the workpiece, and a memory in which a target clamping force corresponding to the shape of the workpiece and a method of machining operation is stored. The control device compares the clamping force detected by the load sensor with the target clamping force stored in the memory and controls the clamper in response to the deviation between the detected clamping force and the target clamping force. The clamping device also has a position detecting means for detecting the axial position of the clamper.

Abstract: A DC commutatorless motor in which one pulse is generated per one revolution is disclosed. The motor comprises: three-phase stator windings; a rotor having 2n magnetic poles (where n is a natural number of 2 or more), a portion of one of the magnetic poles having a magnetic property different from that of said one magnetic pole; three detection devices disposed in the vicinity of said rotor, the detection devices being responsive to a magnetic field generated by the magnetic poles and the portion; first to third amplifiers for amplifying respectively the outputs of the three detection devices; first to third subtracting circuits for obtaining respectively the difference of the outputs of two of the first to third amplifiers; an adding circuit for adding the outputs of the first to third subtracting circuits; and a signal circuit for generating a pulse per one revolution of he rotor on the basis of the output of the adding circuit.

Abstract: An image scanner includes a reflecting plate which is turnable to selectively receive reflected light from an object to be scanned which may be positioned at two different locations. An object at one location can be scanned with one resolution while another object can be scanned at another location with different resolution. The two locations may be spaced at different distances from the reflecting plate to permit accommodation of a wide variety of scanned objects.

Abstract: A controller for properly controlling a rotating speed and a rotational phase of a DC servo motor. A velocity correction signal is obtained by comparing a rotation signal detected from the motor rotating at a predetermined rotating speed, and a phase error signal is detected from the rotation detected signal as well. Both the rotating velocity and phase of the motor are corrected by the controller supplying a signal which is a mix of the velocity error signal and the phase error signal.

Abstract: A system and method for communicating a vehicle with a calling party are disclosed in which even when a communication circuit is interrupted during a data communication of the system with the calling party such as a base station due to a worse circuit condition, the calling from the system to the calling party is carried out without operation of a switch for activating the system to start calling so that the communication with the calling party is restarted. The communication data includes a vehicle identification code (ID information) and/or instantaneous position of the vehicle.

Abstract: A motorcycle exhaust pipe arrangement includes a frame having a head pipe, a main pipe, a down tube, at least one under pipe and a pair of center pipes. A fuel tank is operatively connected to the main pipe. An engine is mounted on the at least one under pipe and is disposed beneath the fuel tank. A seat is mounted adjacent said fuel tank and is disposed above the engine. A rear shock absorber is operatively mounted between the seat and the at least one under pipe for absorbing shock supplied to the seat. The rear shock absorber is centrally disposed relative to a longitudinal axis of the motorcycle. An exhaust pipe is connected to the engine and extends rearwardly therefrom, the exhaust pipe is disposed substantially at a midpoint of the rear shock absorber and extends substantially horizontally therefrom in the longitudinal direction of the motorcycle for lowering the center of gravity of the motorcycle and providing a symmetrical rigid frame for supporting the engine, fuel tank and seat.

Abstract: In this cable connector, there are included a main housing formed with a first aperture, a cover formed with a slot for cable insertion and a second aperture opening to the slot, a means for fixing the cover to the main housing, and a cable connecting element formed as an elongate member. One end of this cable connecting element is adapted to be connected to a cable when pressed against it, for example by being bifurcated, the other end of this cable connecting element is adapted for external terminal contact as for example by being springy, an intermediate portion of this cable connecting element is adapted for press fitting as for example being widened, and a step portion of this cable connecting element between the intermediate portion thereof and the cable connection end thereof functions to perpendicularly displace the plane of the intermediate portion from the plane of the cable connection end.

Abstract: A terminal pin, having a compressed portion the cross section of which is roughly V-shaped, has a pair of arms and a pair of convex contact edges with a concave trail between the convex contact edges. The pair of arms have a uniform thickness and are deformed inwardly when pressed into a through hole defined in a PCB. After being pressed into the through hole, the compressed portion contacts the internal surface of the through hole at four locations, namely, at a pair of external surfaces provided at the ends of the pair of arms and the pair of convex contact edges.

Abstract: A multiplexed signal receiver is arranged such that two independent signals are multiplexed on a single carrier by amplitude and frequency modulation or amplitude and or phase modulation. The multiplexed signal receiver includes a balanced type amplitude limiter and two double balanced type product detectors for amplitude and frequency or amplitude and phase demodulation. The receiver uses the direct coupling between said amplitude limiter and the two product detectors to facilitate the circuit integration thereof on a monolithic semiconductor chip.

Abstract: Incombustible materials are bonded together with a self-burning adhesive composition which is a mixture of an organic polymer base structural adhesive as typified by an epoxy adhesive and an oxidizer as exemplified by an ammonium perchlorate powder, so that the bonded materials can be disassembled nondestructively, if desired, by heating the joint to the ignition point of the composition and leaving the composition in the joint to burn self-supportedly until it vanishes.
