On-vehicle emergency report apparatus, emergency communication apparatus and emergency report system
Publication number: 20030117274Abstract: An on-vehicle emergency report apparatus, an emergency communication apparatus and an emergency report system are disclosed. The emergency report apparatus includes an emergency situation prediction unit for predicting the possibility of a vehicle involved encountering an emergency situation, a report control unit and a communication unit. The communication is established based upon the determination of the emergency situation prediction unit, which predicts the possibility of the vehicle encountering an emergency situation a predetermined time later, based on at least one of the feature quantities including the distance between the vehicle involved and the vehicle running immediately ahead, the relative speed, the relative acceleration, the speed of the vehicle involved, the brake pedal stroke, the steering wheel angle and the expression of the driver.Type: ApplicationFiled: September 17, 2002Publication date: June 26, 2003Applicant: HITACHIInventors: Satoru Kuragaki, Kazuhiko Sato, Tokuji Yoshikawa, Takao Kojima, Toshimichi Minowa -
Patent number: 6449197Abstract: To improve the efficiency for repairing a defect of a large-scale integrated circuit. A semiconductor integrated circuit device comprises, a central processing unit (10), an electrically reprogrammable nonvolatile memory (11) and a volatile memory (12, 13) while sharing a dat bus (16), and utilizes the stored information of the nonvolatile memory so as to repair a defect of the volatile memory. This volatile memory includes volatile storage circuit (12AR, 13AR) for latching the repair information for repairing a defective normal memory cell with a redundancy memory cell. The nonvolatile memory reads out the repair information from itself in response to an instruction to initialize the semiconductor integrated circuit device. In response to the initializing instruction, the volatile storage circuit latches the repair information from the nonvolatile memory.Type: GrantFiled: November 21, 2001Date of Patent: September 10, 2002Assignee: HitachiInventors: Mitsuru Hiraki, Shoji Shukuri

Patent number: 5396034Abstract: A ceramic thin film hybrid circuit board is provided by flattening the surface of a ceramic multi-layer interconnection substrate, forming capture pads on the flattened surface, filling spaces between the capture pads with an insulating layer composed of a glass material or an organic resin material, grinding the resultant surface until the capture pads are exposed to flatness, and laminating a plurality of thin film interconnection layers on the flattened surface. The ceramic thin film hybrid circuit board has an increased package density of mounted electronic parts such as LSIs and the like because failures of thin film interconnection layer generated owing to the roughness of the surface of the ceramic substrate, defects such as voids and the hollows produced with the capture pads are greatly reduced, and is very suitable for large scale electronic computers, in which the wiring length is reduced so as to reduce the signal delay.Type: GrantFiled: March 8, 1993Date of Patent: March 7, 1995Assignee: HitachiInventors: Tsuyoshi Fujita, Shoichi Iwanaga, Hirayoshi Tanei

Patent number: 4337518Abstract: A recursive-type digital filter comprising a calculation circuit. The calculation circuit is arranged to multiply an input signal including at least m-bit signal x.sub.n inputted at a predetermined sampling period and an output signal y.sub.n-k fed back to the input of the calculation circuit in accordance with the input signal x.sub.n after being subjected to a delay of k sampling periods by a.sub.k and b.sub.k coefficients corresponding to the filter characteristics, respectively, and then the products are added thereby to produce data y.sub.n of (m+l) bits satisfying, ##EQU1## and serially deliver the upper m-bit data of the data y.sub.n as an output signal corresponding to the input signal x.sub.n.The filter further comprises a delay circuit for feeding back to the input of the calculation circuit a part of the round off data including the upper (m+1)th bit of the data y.sub.n so that the b.sub.k coefficient is multiplied by the fedback data of the upper (m+1)th bit and the product is added to the data y.Type: GrantFiled: July 28, 1980Date of Patent: June 29, 1982Assignee: HitachiInventors: Makoto Ohnishi, Hiroshi Kuwahara, Narimichi Maeda
