Title: Automatic traveling controller for vehicle
Inventor: NISHIWAKI TAKASHI
IPC: B62D113/00
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To improve the control accuracy of the turning value of a vehicle in its low speed traveling mode by switching a 2nd control means to the 1st one which controls the steering value that is calculated from the target turning value in a low speed traveling mode and controlling the steering angle of the vehicle based on the output of the 1st control means. SOLUTION: A 1st control means 200 consists of a target turning value calculation means 201 which calculates the target turning value from the curvature of a traveling course that is detected by a camera 8 serving as a position detection means and a 1st target steering angle calculation means 202 which calculates a target angle corresponding to the target turning value. When the speed of a vehicle calculated by a turning value calculation means 301 from the outputs of the 1st and 2nd wheel speed sensors is lower than a prescribed level, the output of the means 202 is inputted to a steering angle control means 203 by a switching means 204. Meanwhile, the output of a 2nd target steering angle calculation means 303 is inputted to the means 203 when the vehicle speed is higher than the prescribed level.

Title: Semiconductor device
Inventor: ONDA MAMORU
IPC: H01L25/065
Filed: 1991-10-17
Abstract: PURPOSE:To obtain a compact printed board together with a package and obtain a compact system as a whole, by replacing a part of printed board for mounting with a package when assembling a semiconductor chip three- dimensionally. CONSTITUTION:A first semiconductor chip is installed and wire bonding is performed. Then, a die pad plate 22 with a heat sink is mounted by inserting pins 25 into pin holes 8' and 8. After a second semiconductor chip is installed on the die pad plate 22 and wire bonding is performed, potting is performed with a potting resin. A fin 22' for heat dissipation of the die pad plate 22 has a shape protruding out of a package. Thus, heat dissipation of the present semiconductor device can be improved about three times that of the conventional semiconductor device by mounting the die pad plate 22 having a gland conductor or the fin 22' acting to dissipate heat. Further, a lighter weight can be obtained due to no molding, resulting in about one-third the conventional device in weight.

Title: Thermal head
Inventor: SAIDA KATSUAKI
IPC: B41J2/335
Filed: 1989-10-16
Abstract: PURPOSE:To control the heat-generating peak temperature of a heating resistor uniformly by giving a self-temperature control function to thermal heat itself which does not elevate the temperature of the heating resistor at a specified temperature or higher. CONSTITUTION:A heating resistor 1 is composed of a substance conducting a change, in which electric conductivity is brought to a metallic state on the low temperature side and a nonmetallic state on the high temperature side while using a specific temperature range as a border, such as a phase transition. That is, when voltage is applied to the heat heating resistor 1, Joule heat is generated and the temperature of the heating resistor 1 reaches a specific temperature, a metallic or nonmetallic phase- transition temperature, a resistance value is increased in an approximately insulating manner or a semiconductor manner and currents are interrupted approximately in the heating resistor 1. Consequently, when voltage has a value in proper magnitude capable of increasing a temperature up to at least the phase transition temperature to a resistance value lower than the phase transition temperature of the heating resistor regarding applied pulse width and the pulses, the temperature of the heating resistor is not elevated up to a temperature exceeding the phase transition temperature. Accordingly, the temperature-rise peak temperature of the heating resistor can be controlled uniformly in said phase transition temperature region.

Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of an air fuel ratio control property by learning and correcting an invalid part in the low opening area of a control command value for a purge control valve based on the change of the air fuel ratio per an operation area and setting the control command value for the purge control valve based on a basic value and the learned and corrected invalid part. SOLUTION: A canister purge control valve (CPC valve) 14 is interposed on the way of a purge passage 13 and this is duty-controlled by ECU 30. Meantime, it is investigated whether a learning condition is realized or not. In other words, during an air fuel ratio feedback control and during an evapo-purge and when an evapo-density is higher than a set value, it is judged that the learning condition is realized and a duty correction coefficient is set in response to a present operation area and this correction coefficient is added to a learning value and the learning value is renewed. A value added an invalid duty to the basic duty of CPC valve 14 is corrected by the learning value, while maintaining an air fuel ratio control property in entire purge execution area and the duty is set and CPC valve 14 is driven.

Title: Numerical controller having automatic shift function of machining position of tool and its control method
Inventor: HOTTA NAOHIRO
IPC: B24B21/18
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To control the machining position of a tool in an appropriate position by shifting the machining position of the tool by a compensation value of a tool diameter set in a numerical controller under the conditions that the using frequency of the tool set in database and the counted number of a counter are coincided with each other.

The using frequency set therein and the counted value of a tool counter 12 are compared and calculated in a calculating part 13 in the NC. If the counted value of the counter 12 is coincided with the set value of the using frequency, it is automatically changed into the compensation value of the tool diameter set according to the using frequency of the tool based on the data of a tool trajectory calculating part 15 for deciding the machining position of the tool in a tool diameter compensation calculating part 15 in the NC. That is to say, the machining position of the tool is shifted.

IPC: F01L13/00
Filed: 1988-10-25
Abstract: PURPOSE:To synchronize always the completion of switching the intake and exhaust overlap period and the start of supercharging by setting the time difference between the time from the start of switching the intake and exhaust overlap period to the start of switching a clutch of a mechanical supercharger, and the engine speed becomes lower, changing this time difference larger. CONSTITUTION:Since the time difference is set by a timer means 64 between the time from the start of switching a timing change device 30 by a timing switching means 62 to the start of switching a clutch 44 by a clutch switching means 63, at the time of switching to the supercharging area, the supercharging is started after the increasing of the intake and exhaust overlap period. In this case, since the engine speed becomes lower, the time difference of the timer means 64 is changed larger, even if the engine speed lowers and the oil pressure lowers in response of it so that the action delay of the timing change device 30 is increased, the completion of switching the intake and exhaust overlap period and the start of supercharging are always synchronized so that the generation of knocking and the generation of the torque shock are prevented.
