Patent JP-H03195029-A (JP)
Title: Field-effect transistor
Inventor: SHIRAISHI YASUSHI
IPC: H01L29/812
Filed: 1989-12-25
Abstract: PURPOSE:To obtain a field-effect transistor whose source resistance is low by a method wherein a potential barrier layer at an ohmic-electrode formation part is doped with a monoatomic layer of impurities. CONSTITUTION:The following are formed: a semiconductor layer 2 of a first conductivity type; a semiconductor layer 4 whose forbidden band width is larger than that of the semiconductor layer 2; and an impurity-doped monoatomic layer 3, of the first conductivity type, which has been formed in the semiconductor layer 4 so as to be parallel with the semiconductor layer 2. Since the impurity-doped monoatomic layer 3 obtains a high carrier concentration, it is reduced that the activation of impurities is suppressed by a mutual action of impurity atoms. Consequently, when the impurity-doped monoatomic layer 2 is buried inside the potential barrier layer 4, a parasitic resistance in the potential barrier layer 4 at an ohmic-electrode formation part is reduced. Thereby, it is possible to obtain a hetero-type field-effect transistor whose source resistance is low.

Title: Semi-automatic transmission
Inventor: IDOGUCHI MASARU
IPC: B60W10/10
Filed: 1993-12-28
Abstract: PURPOSE:To avoid the starting failure of a vehicle caused by the failure of a clutch pedal switch by providing a means for executing start control in disregard of the operating information of a clutch pedal when an engine is rotated while the rotation of a transmission is stopped according to rotation information in an emergency mode. CONSTITUTION:When an emergency operation button 13 is operated, a control circuit 6 receives the operation input, sets an emergency mode and lights an emergency mode display means 14 disposed at the outer periphery of the emergency operation button 13 so as to display the setting of the emergency mode. The control circuit 6 then takes in the rotating speed of an engine and the rotating speed of a transmission input shaft from a rotation sensors 51, 52. When the engine is in the rotating state and the transmission input shaft is in the stop state, the control circuit 6 takes in shift position information from a speed change lever 3, and judges whether the speed change lever 3 is in a start position. When the speed change lever 3 is not in the start position, the control circuit 6 goes back to the position information taking-in process of the speed change lever 3 but executes start control in the case of the speed change lever 3 being in the start position.

IPC: B23K26/361
Filed: 1990-11-30
Abstract: PURPOSE:To reduce thermal influence to a work without remaining sludge by selectively trimming a part, where at least two directions mutually crossed at right angles in the working part are opened. CONSTITUTION:At first, laser beam trims the part 7 at end of silver electrode 2 as straight line-state and successively, the laser beam is shifted to inside by distance corresponding to condensed diameter 6 thereof an again trims to the successive part 8 as the straight line-state and this movement is repeated till obtaining the prescribed trimming quantity. Then, as the sludge can be spattered to upper part and in the crossing direction at right angles, i.e., the opened side two directions, even if a high output of laser beam is to used, the working without remaining the sludge can be executed. In this case, as the output of laser beam is set to a little higher value than the threshold value for working of the silver electrode 2, the thermal influence is a little.

Title: Vehicle door structure
Inventor: KIMURA KOICHI
IPC: B60J5/00
Filed: 1992-12-18
Abstract: PURPOSE:To provide a vehicle door structure whereby the degree of freedom in molding trim is not restricted by linkage and the overall rigidity of the door is not deteriorated even if a relatively large opening is notched in an inner panel. CONSTITUTION:The greater part of linkage 29 extending rearward from an inside handle 28 is disposed nearer to the outside of the vehicle than the interior general surface 23a of an inner frame 23 is, so the need for keeping a special space between the linkage 29 and trim is eliminated, resulting in enhancement of the degree of freedom in molding the trim. Since a closed cross section portion extending along the longitudinal direction of the door is formed by waist reinforcement 18 and by the portion of the inner frame 23 corresponding to the reinforcement, the overall rigidity of the door is enhanced although a relatively large opening 17 is notched in an inner panel 14.

Abstract: PURPOSE:To switch the current with high accuracy by dividing the gate voltage of a 4th MOS transistor TR out of two MOS TRs forming a differential switch with the 5th and 6th MOS TRs having their gates and the drains connected to each other. CONSTITUTION:The gate of the TR 5 is set at a voltage level equal to the power voltage divided by a PMOS TR 2 and an NMOS TR 6 having their drains and the connected to each other, i.e., at a voltage level between the high levels. In regard of a differential switch consisting of the TR 4 and 5, one of both TRs having a higher level of gate voltage conducts with the other TR cut off respectively. Thus the current of a source 7 flows to a current output terminal 8 through the TR 5. Meanwhile the gate of the TR 4 is set at a high level when a signal of a low level is inputted to a signal input terminal 9. Then the current of the source 7 flows to a power terminal 18 through the TR 4 and never flows to the terminal 8.

Title: System and method for managing adjacent channel interference in channel-configuration cellular system
Inventor: MACHIRUDO BENBUENISUTO
IPC: H04W16/02
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To attain an overall S/I ratio object by employing an even/odd number cell designation method, a vertical channel set configuration method, and a minimum adjacent circuit method so as to avoid collision of adjacent channels among cells and among adjacent sectors in sector-configured cells so as to manage adjacent channel interference.

In this case, a center 220 receives input data and uses the even / odd number cell designation method and the vertical channel set configuration method to exclude collision between adjacent channels among cells and among adjacent sectors in sector-configured cells. Furthermore, the center 220 employs the minimum adjacent circuit method so as to reduce number of adjacent edges of adjacent cells or adjacent sectors in a regular channel assignment method. Thus, the interference of adjacent channels is managed as a function of a service quality coefficient and the overall S/I ratio object is attained.
