Title: Plane antenna
Inventor: KURODA SHINICHI
IPC: H01Q13/08
Filed: 1991-06-03
Abstract: PURPOSE:To realize the plane antenna formed thin under the condition of an antenna for both transmission and reception and for exciting a circularly polarized wave whose transmission/reception frequencies are apart by several % or over. CONSTITUTION:A circular radiation conductor 11 and a torus radiation conductor 12 are arranged opposite to a ground conductor 3. The radiation conductors 11,12 are arranged concentrically on a same plane and a distance (d) is set smaller than a thickness (t) (thickness of board) of, e.g. a dielectric body 2 to cause inter-coupling. The size of the radiation conductors 11, 12 are selected to be excited in same groups of modes TMn1, TMn2 (n is an integral number of being one or over) in an optional frequency band. Two frequencies are used in resonance with the radiation conductors 11, 12 by having only to a feeding point 4 to the radiation conductor 11 by the effect of interlinking. Since the conductors are resonated in the two frequencies, the conductors are applied to both the transmission reception antennas whose transmission reception frequencies are apart by several % or over and the antenna copes with excitation of a circularly polarized wave by applying two-point feeding with a phase difference of, e.g. 90 deg. and the merit of the thin profile is sufficiently utilized because of single layer structure.

IPC: B65D85/86
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To enable bonding an IC chip to a board with high efficiency without damaging rigidity, durability and resistance to heat of a metal carrier, by constituting a mounting part of a board of a carrier for flip chip mounting, of heat- insulating material. SOLUTION: A carrier for flip chip mounting is constituted, by setting heat- insulating material 9 in a trench part 11 of a base plate 10, putting a press plate 7 on the material 9, and bonding suitable portions by spot welding or the like. A frame 8 for board mounting formed in the press plate 7 is made to conform just to the upper surface of the heat-insulating material 9. When the board is mounted along the frame 8 for board mounting, the bottom surface of the board comes into contact with the heat-insulating material 9. As the insulating material 9, glass cloth impregnated with epoxy resin, engineering plastic, etc., which have thermal conductivity lower than that of metal and can endure a practically operating temperature are used. Thereby the bonding of an IC chip and a board is effectively enabled.

Title: Shorter feeding-section multiplex feeding method
Inventor: FUJIE JIYUNJI
IPC: H02P25/064
Filed: 1992-04-24
Abstract: PURPOSE:To reduce a feeding voltage at a wayside coil, by using a unit feeder section (OS) made up of feeder sections shorter than a train in length, and providing a given number of shorter feeding sections corresponding to a given design voltage. CONSTITUTION:When feeder division switches (OC) 6 to 9 have been closed, a train 18 located between feeder sections (OS's) 12 to 14 is fed with power while OC's 10 to 11 are opened so as not to feed the train. After the train moves half the OS and passes the OS 12, OC's 6 to 9 are closed and the OC 6 is opened. Then, the OC 10 is closed when the train approaches an OS 16. Likewise when the train 18 moves half the OS, the OC's 7 to 10 are closed and the train 18 between OS's 13 to 15 is fed with power while the OC's 6 and 11 are opened so as not to feed the train. In a quadruplex feeder method, when the unit OS is made equal to half the train length, two OS's can cover one vehicle length to feed. Consequently, four OS's are used to feed the train in a normal time, but the feeder voltage can be reduced nearly to half.

Title: Cutoff device for printed board
Inventor: OTSUKI YUKIHISA
IPC: B26D7/10
Filed: 1990-05-22
Abstract: PURPOSE:To extremely reduce the impact at the time of cutoff, by providing a cutting edge having a heating means. CONSTITUTION:A cutting edge 1 is held at constant temperature by a heater block 2 at a constant temperature, the temperature thereof is set by a temperature controller 5 higher than the softing temperature of the resin which composes a board 11, which is softened at the part brought into contact with the cutting edge 1. Thus, it is cut with the edge tip of the cutting edge 1 being coming into the board 11 without applying a large force on the cutting edge 1. The necessary load for dividing the board 11 is therefore reduced and the impact at the time of cutoff is extremely reduced.

When the operation end deciding circuit 24 decides the end of the operation for each type of the operation, the operating time cumulatively added for each type of the operation being stored in the storing circuit 23 is read. Thus, a display for a warning can be executed before and after the operation.

Title: Air-fuel ratio control device for engine
Inventor: KANAMARU YOSHIKAZU
IPC: F02D45/00
Filed: 1990-05-21
Abstract: PURPOSE:To prevent torque shock due to the sudden change in air-fuel ratio caused by the dissolution of learning values, when the learning control of air-fuel ratio is shifted from a specific operating region being executed to a nonspecific operating region, by attenuating the learning value to zero with the damping factor corresponding to the learning value at that time. CONSTITUTION:When learning control is shifted by a control means 40 from a specific operating region being executed to a nonspecific operating region where learning control is not carried out, if the shift in the operating regions is detected by an operating-region detecting means 37, the learning value is attenuated by a learning-value attenuating means 41 to zero with the damping factor corresponding to the learning value at that time. Thus, at the time of operating-region shift, the occurrence of torque shock due to the sudden change in air-fuel ratio caused by the dissolution of learning values can be prevented, and also the bad influence given to the engine performance such as operability, fuel consumption, and emission performance due to a large deviation in the air-fuel ratio caused by the nonconformity in learning values can be restrained.

Title: Revolution number detector
Inventor: ICHISE TOSHIHIKO
IPC: G01P3/48
Filed: 1982-07-30
Abstract: PURPOSE:To obtain exactly a pulse output proportional to the number of revolutions without retriggering a monostable multivibrator basing on noise included in an input continuing the integration of a voltage generated at the primary side of an ignition coil with a long time constant circuit during the opening of a point. CONSTITUTION:If the point is opened, the voltage generated at the ignition coil 11 is rectified through a diode D1 and R1, C1 and integrated and held at Zener voltage or less by a zener diode ZD1. An output of a condenser C1 is compared with a reference voltage V1 by a comparator 13. If the comparator output attains to H, a distable multivibrator 4 is set, a transistor Q1 is turned off and C2 is charged. The voltage of C2 is compared with a reference voltage V2 by a comparator 15 and if it exceeds V2, the output becomes to L. After an FF14 is set like this, the time width until the comparator 15 becomes to L is generated as an output of a monostable multivibrator from an AND circuit 16 and the pulse output of constant width corresponding to the numbers of revolutions can be obtained.
