Title: Control method for engine
Inventor: AOKI TAKASHI
IPC: F02D29/02
Filed: 1989-07-24
Abstract: PURPOSE:To suppress the fluctuation of an engine output and a car speed during turn running by inhibiting selection of the valve operational characteristic, in the case of an actual steering amount larger than the selection-inhibiting steering amount of the valve operational characteristic calculated in accordance with the car speed. CONSTITUTION:In the case of an engine E in which a variable valve timing lift mechanism VT, with the valve operational characteristic selectively controlled to the high speed/low speed valve operational characteristics by a selector valve 91, is provided to control its opening and closing by a control unit CU, output signals of a car speed sensor 101 and a steering angle sensor 102 are input to the control unit CU. A selection-inhibiting steering amount (or selection-inhibiting steering amount change rate) of the valve operational characteristic is calculated in accordance with a car speed, and in the case of a steering angle (steering amount change rate), detected by the steering angle sensor 102, larger than the selection-inhibiting steering amount (selection-inhibiting steering amount change rate), selection of the valve operational characteristic is inhibited.

Title: Searching system for plan problem
Inventor: YUGAMI NOBUHIRO
IPC: G06Q50/04
Filed: 1990-07-19
Abstract: PURPOSE:To attain rapid search by adding a hypothesis to the current set of hypotheses by a search control part based upon a non-contradiction signal outputted from a condition expression control part and then selecting other searching nodes by a contradiction signal. CONSTITUTION:The search control part 11 in a processor 10 determines the selection of the succeeding job to be arranged out of unarranged jobs and sends its information to a condition expression forming part 12. The forming part 12 forms a condition expression for expressing the contents selected by the control part 11 and sends the formed expression to the conditions expression control part 13, which adds the sent condition expression to the set of condition expressions at that time, checks the non-contradiction of the new set of condition expressions and sends the checked result to the control part 11. At the time of receiving the information of non-contraction from the control part 13, the control part 11 arranges the succeeding job, or at the time of receiving the information of contradiction, arranges the job concerned on another position. Consequently, rapid search is attained.

Title: Semiconductor integrated circuit device
Inventor: TANBA HIROKO
IPC: H01L21/822
Filed: 1994-07-21
Abstract: PURPOSE:To protect the input MOSFET's in an interface unit by placing between a plurality of power supply terminals both of unidirectional elements that are provided with so high a threshold voltage as to be turned off when power is being normally supplied. CONSTITUTION:MOSFET's Q1-Q6 with a diode connected are placed between different power supply terminals VA, VD, VX. These MOSFET's Q1-Q6 are provided with so high a threshold voltage that they will not be turned on in ordinary operating condition. This allows a thick field insulating film to be used for gate insulating films; so-called parasitic MOSFET's are used. Thus, the threshold voltage of the n-type aluminum parasitic MOSFET's Q1-Q6 is used, and potential difference between independent power supplies, which may cause the electrostatic breakdown of interface elements between the independent power supplies, is thereby canceled. This avoids the electrostatic breakdown of interface elements.

Title: Exciter of engine drive generator
Inventor: SANGO MASAYUKI
IPC: H02P9/04
Filed: 1983-10-12
Abstract: PURPOSE:To reduce the drop amount of the output voltage of a generator by supplying the output of other current transformer provided in a load line of the generator to an exciting winding at heavy load starting time to increase the exciting current. CONSTITUTION:A load application detector 5 outputs a load application signal when the current or a voltage is larger than the prescribed value at the load applying time. A heavy load starting time thyristor controller 4 turns OFF a thyristor Q when a load application signal is inputted, and normally superposes the current of a current transformer CT2 which is bypassed in a route of a diode D3 and a thyristor Q on a field winding W1. When the fact that the rush current of a load 2 is reduced so that the rotating speed of the engine is reset is detected from the output of a F/V converter 6, the controller 4 resets the operation to shift the exciter to the normal state.

Abstract: PROBLEM TO BE SOLVED: To eliminate the generation of the non-welded space of an interface between a lead part pole and a strap by providing a cutout on the side facing to the lead part pole of an additional lead for forming the strap. SOLUTION: By shaping an additional lead 10 to have a cutout 11 on the side facing to a lead part pole 4, the welded surface of the pole 4 to a strap is exposed and a plasma arc enters into the entire welded surface to enhance welding properties. A comb jig 1 is fit into a homopolar electrode ear part 2 of an electrode plate group 6, a patch metal 3 is placed on a predetermined position and the lead part pole 4 and the additional lead 10 for forming the strap are placed in a predetermined position of the jig 1. The additional lead 10 is provided with the cutout 11 on one part thereof and the cutout 11 is placed on the jig 1 so that the cutout 11 is on the side abut to the lead part pole 4.  Since the plasma arc generated from a plasma torch can reach the under part of the pole 4 from the cutout 11, the pole under part is melted sufficiently and a non-welded part is not generated between the strap and the pole 4.

Abstract: PURPOSE:To generate the structure of an offset in a self-alignment manner by a method wherein the thicknesses of sidewalls, which are generated on both sides of a gate electrode by anisotropic etching in the direction of inclination, are made to differ from each other, whereby these thicknesses are each set intact as the interval between a source and the gate electrode and the inverval between a drain and the gate electrode. CONSTITUTION:An n-type active layer 2 is formed in the surface layer part of a semi- insulative GaAs substrate 1 and a gate metal film 5, which is used as a Schottky junction and consists of a tungsten silicide, is provided on this layer 2. Then, a reactive dry etching is performed to turn the film 5 into a gate electrode 5A, the whole surface including this electrode 5A is covered with an SiO2 film (an Si oxide film) 6 and SiO2 films 6s and 6d are made to remain only on the sidewalls of the electrode 5A by performing an anisotropic etching using C4F8. Here, as the incident angle of ions is slanted on the side of a source to the substrate 1, the thickness of the sidewall 6s becomes thinner than that of the sidewall 6d. After that, ions are implanted using the electrode 5A and the sidewalls 6s and 6d as masks to form high-concentration carrier layers 4s and 4d, which are used as the source and a drain, on each side of both sidewalls and a large offset is grown between the layer 4d and the electrode 5A.
