Patent number: 6694614Abstract: A laser processes a circuit board including at least two layers. The two layers are a conductive layer with a plurality of holes and an insulating layer. The conductive layer is disposed on a surface layer of the insulating layer which is to be processed by applying a laser beam to portions of the insulating layer corresponding to the holes of the conductive layer. The circuit board is irradiated with the laser beam, and a reflected laser beam is detected, whereby the laser processing of the insulating layer corresponding to an abnormal hole in the conductive layer is stopped, if the detected value of the reflected laser beam is an abnormal value differing from a desired value. Also, the insulating layer corresponding to the hole is processed when the detected value of the reflected light conforms to the desired value.Type: GrantFiled: May 31, 2001Date of Patent: February 24, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Katsuichi Ukita, Kazuhide Isaji, Hideaki Nagatoshi, Hidehiko Karasaki, Hisashi Kinoshita, Tsutomu Yano

Patent number: 6586703Abstract: This is to present a laser machining method and a laser machining apparatus for drilling holes, capable of achieving conduction securely between adjacent conductive layers, by detecting the machining state of a workpiece adequately, and controlling the machining. For this purpose, the number of laser pulse outputs capable of machining securely is preset. During laser machining, reflected laser beam intensity from the workpiece and incident laser beam intensity are detected, and the machining state of the workpiece is detected. As a result, when judging the workpiece has reached a desired machining state, laser machining is finished if the number of times of laser machining has not reached the set number of laser pulse outputs. If it is judged that the workpiece has not reached the desired machining state, laser machining is finished when reaching the set number of laser pulse outputs.Type: GrantFiled: June 4, 2001Date of Patent: July 1, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazuhide Isaji, Hidehiko Karasaki, Hisashi Kinoshita, Makoto Kato

Patent number: 5892650Abstract: A solenoid valve driving device includes a bypassing current path of which one end is connected to a point between a first switching device and a first solenoid valve and another end is connected to a point between a second switching device and a second solenoid valve, and an element disposed in the bypassing current path and having a characteristic that causes current to flow from the first switching device side to a second switching device side. By adopting the above described constitution, through current generated when the first switching device is switched from an OFF-state to an ON-state during duty control of the first switching device can be suppressed by the inductance of the second solenoid valve. In this way, one solenoid valve among a pair of the first and second solenoid valves, which is not operated, has a function of suppressing the through current.Type: GrantFiled: November 28, 1997Date of Patent: April 6, 1999Assignee: Denso CorporationInventors: Hisashi Kinoshita, Kazutoshi Yogo, Takahiro Kiso

Suspension control system for controlling suspension of automotive vehicle based on wheel speed data
Patent number: 5444621Abstract: A suspension control system capable of controlling a suspension of an automotive vehicle in such a manner as to improve the riding comfort and maneuverability of the vehicle without the need for many sensors is disclosed, in which a speed difference signal obtained by subtracting an estimated vehicle speed from a wheel speed is filtered with band-pass filters which pass sprung resonance frequency components and unsprung resonance frequency components, respectively. After amplification, the filtered speed difference are compared with a reference value so that a damping force of a shock absorber is set in accordance with a road surface condition. Since the damping force of the shock absorber is shifter by using only information based on the wheel speed detected by a wheel speed sensor, a total number of sensor to be mounted on the vehicle for controlling the suspension can be considerably reduced. The suspension control system is simple in construction and can be manufactured at a relatively low cost.Type: GrantFiled: June 10, 1992Date of Patent: August 22, 1995Assignee: Nippondenso Co., Ltd.Inventors: Eiju Matsunaga, Akira Fukushima, Noriyuki Nakashima, Toshiyuki Murai, Shinya Takemoto, Mikio Tanabe, Hisashi Kinoshita -
Patent number: 5319294Abstract: An automatic offset adjusting apparatus for current detectors in a digital controller for a servo motor is constructed so that, when errors occur in offset correction values due to a temperature change and the like while the servo motor is in operation, an electrical angle detecting unit detects a ripple of the torque of the servo motor, on the basis of a ripple of a torque command value, and detects a first electrical angle, where the torque command value becomes maximum, and a second electrical angle, where the torque command value becomes minimum, based on an electrical angle signal of the servo motor, a judgement unit judges whether or not offset correction errors have occurred on the basis of a difference between the first and second electrical angles, and, if the judgement unit judges that the offset correction errors have occurred, a correction unit adds adjustment values for the offset correction values corresponding to the first electrical angle to the respective offset correction values to update thType: GrantFiled: May 24, 1993Date of Patent: June 7, 1994Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masahiro Ohto, Hisashi Kinoshita, Nin Kake, Yoshihiro Ino
