Filed: 1987-08-11
Abstract: PURPOSE:To allow an accurate bonding by ensuring that a predetermined length of a wire tip is pinchingly pressed between the first bonding section and a wedge tip end at the time of bonding the first bonding section. CONSTITUTION:A bonding wedge 1 is once lifted, and a wire 2 being of a length required for the first bonding is prepared by pulling out until such time as the bonding wedge 1 is moved over to the first bonding section 7 after completion of the bonding of the second bonding section 8.

Abstract: PURPOSE:To enable recognition of an object having a curved surface without searching a corresponding point on the object by a method wherein images of an object are obtained from two different directions and contour lines extracted on the basis of said images are made to be approximate to a plurality of straight lines. CONSTITUTION:Images of an object are sensed from two different directions by image sensing devices 1 and 2, and contour lines are extracted on the basis of sensed image signals in contour-line extracting elements 3 and 4.

Title: Data transmission system
Inventor: KYODA TADASHI
IPC: G06F13/20
Filed: 1985-09-11
Abstract: PURPOSE:To reduce the system cost by detecting a synchronizing signal in a data flowing to a data transfer bus in each system, using the synchronizing signal to operate a counter and sending a data to the data transfer bus based on the value of the counter. CONSTITUTION:Units 13-15 are connected to the same data transfer bus and the data transmission/reception is applied between the units via a data transfer bus 1. When a data stream starts flowing to the data transfer bus 1, each unit fetches the data and when a flag detector 7 detects a start flag 21 at each time (t) and an AND gate 22 detects a specific pattern, the output of the AND gate 22 becomes the trigger condition of a counter 9 to activate it. When the AND gate 22 detects a flag except the start flag 21, the result is sent to a NOT gate 23 and the output resets the counter 9. In transmitting/receiving a data by using a common data bus between plural systems, since each unit manages the use of right of the data bus by itself, a centralized control section and a control signal line deciding the priority for the use of data bus are not required.

Abstract: PURPOSE:To maintain stable rotation of a power take-off shaft by enabling an electronic governor provided to a fuel injection pump to be set in an all speed mode if a power is extracted by power take-off when a transmission is in a neutral condition. CONSTITUTION:An automatic transmission A is coupled to a Diesel-engine D having a fuel injection pump C provided with an electronic governor B, and is changed over under control by an actuator F so that an appropriate gear position calculated by a gear position calculating means E is established. In this arrangement, a power take-off (PTO) G for extracting a desired power for a mode other than a running mode is provided in the transmission A.

Title: Static type variable frequency power supply device
Inventor: SATO KATSUO
IPC: H02M7/155
Filed: 1987-08-12
Abstract: PURPOSE:To suppress the change in reactor output by fixing the memory value of the control state quantity provided between a speed change rate limiter and V/F (voltage-frequency) converter in the control system of a static type power supply device by the fault signal of a speed command device. CONSTITUTION:The speed signals applied from the speed command deice 9 are transmitted via a speed lower limit limiter 10 and the speed change rate limiter 11 to the memory 12. One of the signals is transmitted to a voltage controller 15 which controls the output voltage of the power supply device and the other to the V/F converter 13 which suppresses the output frequency. The output of the converter 13 is transmitted via a ring counter 14 to an inverter part which determines the output frequency of the power supply device. The output of the controller 15 is transmitted to a current control system 16 which controls the input current value of a current rectifier 4 as a feedback quantity; further, the output is transmitted via a phase regulator 17 to the respective thyristors of the rectifier 4 by which the output voltage of the power supply device is determined. The control signal to the converter 13 and the controller 15 can be suppressed to only the fluctuation in the slight period when the fault signal of the speed controller is transmitted to the memory 12 even if the fault arises in the speed command device.

Title: Structure for coupling vehicle side member
Inventor: NAKAJIMA MASAYUKI
IPC: B62D25/20
Filed: 1989-07-31
Abstract: PURPOSE:To sufficiently absorb impact by a side member by a method wherein an end of at least one of a front and rear members on the overlapped part of both members is tilted in a widthwise direction of a body. CONSTITUTION:On an overlapped part 12 of a front and a rear members 3, 4 constituting a rear side member 2, an end of at least one of these members 3, 4 is tilted with respect to the widthwise direction of the vehicle. Thus rigidity on a part from a mediate part to the overlapped part 12 of the front and rear members 3, 4 varies more gently than a case where the overlapped part 12 is aligned to the widthwise direction of the vehicle. Therefore, when impact is applied from the rear end of the rear side member 2 toward the front, concentration of stress in the vicinity 13 of the overlapped part 12 of the front and rear members 3, 4 is suppressed thereby preventing the end of the rear side member 2 from being bent easily with the vicinity 13 as the center.
