Patent number: 7602477Abstract: A laser radar sensor includes a light emitting circuit, a light receiving circuit, an object detection circuit, and a CPU. The object detection circuit has a summation block, a noise reference determination block, a noise reference storing block, and a differentiation block. The summation block sums up photoreception signals outputted from a photoreceptor also included in the radar sensor and produces a summation signal. The noise reference determination block determines the summation signal outputted in a condition that no object is present in a detection area as a noise reference signal. The noise reference storing block stores the noise reference signal. The differentiation block calculates a subtraction signal by subtracting the noise reference signal from the summation signal for removing a noise component from the summation signal. Object detection is performed based on the subtraction signal.Type: GrantFiled: March 9, 2005Date of Patent: October 13, 2009Assignee: Denso CorporationInventors: Mitsuo Nakamura, Katsuhiro Morikawa

Patent number: 7563042Abstract: A substrate carrying apparatus includes an arm body; supporting portion provided in the arm body and adapted to support a region inside the periphery of the rear face of the substrate; a one-side restricting portion and an other-side restricting portion provided at opposite positions across the periphery of the substrate to restrict the peripheral positions of the substrate; and liquid receivers provided between each supporting portion and each restricting portion. A liquid drop attached to the rear peripheral portion of the substrate flows down on the bottom face of each liquid receiver. Even though repeated substrate carrying operations are performed and thus the liquid drop is accumulated in each liquid receiver, there is no risk that the liquid drop in each liquid receiver would be scattered in the air by the action of the periphery of the substrate and hence the scattered liquid would be attached again onto the surface of the substrate.Type: GrantFiled: August 16, 2006Date of Patent: July 21, 2009Assignee: Tokyo Electron LimitedInventors: Masahiro Nakaharada, Seiki Ishida, Taro Yamamoto, Katsuhiro Morikawa

Patent number: 7158217Abstract: In a vehicle radar device, a predetermined number of received light signals output based on a predetermined number of laser beams radiated from a radar sensor are integrated by an integrator to produce an integrated signal.

There are set a plurality of ranges of the received light signals to be integrated, each being shifted by one received light signal. This minimizes a drop in the angular resolution based on the integrated signals.Type: GrantFiled: October 14, 2003Date of Patent: January 2, 2007Assignee: Denso CorporationInventors: Yoshiaki Hoashi, Katsuhiro Morikawa

Patent number: 6757054Abstract: In a shift clock signal generating apparatus, a delay line includes a plurality of unit delay elements connected in cascade. A reference clock signal propagates in the delay line while being successively delayed by the unit delay elements. Switches have first ends connected with output terminals of the unit delay elements respectively, and second ends connected with a shift clock signal output path. When specified one among the switches is in its on position, a delayed clock signal which results from delaying the reference clock signal by a prescribed time interval is transmitted via the specified switch to the shift clock signal output path as a shift clock signal. The specified one among the switches is determined on the basis of data representing a phase difference of the shift clock signal from the reference clock signal. The specified switch is set in its on position.Type: GrantFiled: April 25, 2003Date of Patent: June 29, 2004Assignee: Denso CorporationInventors: Takamoto Watanabe, Katsuhiro Morikawa

Patent number: 6665056Abstract: A method and apparatus of measuring a distance to a reflection object is disclosed. A sensitivity time control (STC) process is applied to a received signal from the reflection object to provide an STC-processed signal. The radar apparatus includes a controller. The controller obtains a quantity corresponding to the distance from a transmission time of the transmission signal and a detection time of the STC-processed signal. The quantity is corrected by using a first correction value associated with the intensity of the STC-processed reflection signal to provide a corrected quantity. The corrected quantity is further corrected by using a second correction value associated with the corrected quantity and the intensity of the STC-processed reflection signal to correct the error regardless of the intensity of the STC-processed reflection signal.Type: GrantFiled: November 14, 2002Date of Patent: December 16, 2003Assignee: Denso CorporationInventors: Noriaki Shirai, Katsuhiro Morikawa, Yoshie Samukawa, Keiji Matsuoka, Toyohito Nozawa

Patent number: 6657704Abstract: A forward electromagnetic wave is generated in accordance with a succession of pseudo random noise code signals. An echo electromagnetic wave caused by reflection of the forward electromagnetic wave at an object is converted into a received signal. Direct-current and low-frequency components are removed from the received signal to generate a filtering-resultant signal. The filtering-resultant signal is compared with a preset decision reference voltage to generate a binary signal. The binary signal is sampled into received data. Calculation is made as to a correlation between the received data and the pseudo random noise code signal. The distance to the object is computed on the basis of the calculated correlation. The pseudo random noise code signal is repetitively generated to produce a succession of the pseudo random noise code signals during a surplus time covering a stabilization time taken by the received signal to stabilize in direct-current voltage level.Type: GrantFiled: May 30, 2002Date of Patent: December 2, 2003Assignee: Denso CorporationInventors: Noriaki Shirai, Katsuhiro Morikawa
