Title: Laser igniting apparatus for internal combustion engine
Inventor: HATSUTORI TADASHI
IPC: F02P23/04
Filed: 1981-05-18
Abstract: PURPOSE:To improve durability and reliability of a laser igniting apparatus, by omitting a laser beam distributing means or other through employment of such an arrangement that a single laser beam produced by a laser oscillator of the laser igniting apparatus is passed through combustion chambers of an internal combustion engine and it is focused in two cylinders by use of convex lenses. CONSTITUTION:A laser pulse emitted to meet with the ignition timing of either one of a plurality of cylinders under the control of a laser pulse generator controlling circuit 2 is passed through the upper end portions of respective combustion chambers and makes focuses F1-F4 at positions near the axis of symmetry in respective combustion chambers by means of convex lenses 4-1-4-4. Here, the energy of laser pulse is so selected that dielectric breakdown is caused at the density of air-fuel mixture at the time when ignition is to be caused. However, since the density of mixture in other cylinders at te time is lower, dielectric breakdown is not caused in said other cylinders by the same level of energy. Thus, it is enabled to supply energy selectively to the cylinder in which ignition is to be caused and to thereby cause ignition and combustion of mixture. Further, laser pulse emitted to meet with the ignition timing of next cylinder causes dielectric breakdown and hence ignition of mixture only in said next cylinder.

Title: Current limiter
Inventor: TSUYA NAOKI
IPC: G05F1/573
Filed: 1985-04-11
Abstract: PURPOSE:To limit the current with a margin to the normal value even when a voltage of a power source is fluctuated by generating a reference voltage source of an operational amplifier by a resistance division circuit to a power supply source. CONSTITUTION:A reference voltage Vs of an operational amplifier 5 is formed by the resistance division circuit comprising resistors 8,9 form a voltage of the power source 1. Thus, the reference voltage Vs changes depending on the voltage of the power source 1. On the other hand, a voltage at an inverting input of the operational amplifier 5 is formed based on a current detecting voltage VR across a resistor 4. Since the reference voltage of the operational amplifier changes depending on the voltage of the power source, a current limit with a proper margin always to the normal value over a wide voltage range is applied to the load whose current changes depending on the voltage.

Title: Altitude identification display system for aircraft
Inventor: ASAKA KAZUMI
IPC: G01S7/22
Filed: 1989-03-28
Abstract: PURPOSE:To lower a erroneous recognition rate with a higher recognition property by changing a display brightness of a aircraft data on a display screen corresponding to altitude information. CONSTITUTION:A display brightness of an aircraft data of an aircraft with altitude information 0-H1 is set at B1 of a low brightness in such a manner that thereafter, the brightness is increased as altitude rises as shown by B2 from H1-H2 and finally, the maximum brightness is set to reach Bn when the altitude information exceeds Hn. Such a setting of the brightness can be implemented easily by setting and displaying a degree of a brightness modulation in a display of the aircraft data in an intensity easy to discriminate in visual recognition corresponding to altitude information beforehand. Here, is should be noted that a high brightness Bn is saturated on a screen so that there is no brightness difference from a brightness Bn-1 of one-level lower level. Thus, an aircraft data of the same degree of altitude is displayed at the same brightness thereby lowering possibility of erroneous recognition with easier identification.

Title: Energizing mechanism for card edge connector
Inventor: HAWAADO UORESU ANDORIYUUSU JIY
IPC: H01R12/70
Filed: 1984-04-17
Abstract: The invention disclosed herein relates to a biasing means provided in one end of a card-receiving slot of a card edge connector. The biasing means includes a spring loaded wedge slidably positioned in a sloping passage at one end of the slot. The wedge includes a vertical surface which engages a side of the card as the card is inserted in the slot. The wedge moving down the sloping passage increases the slot length to accommodate the card width without exerting significant longitudinal force against the end walls of the connector. Further, the wedge cannot be moved up the passage by an uneven force being exerted on the card; accordingly, the card can only be removed from the slot in a straight line.
