Title: Signal detection dome
Inventor: KANDA JIYUNJI
IPC: G01S15/08
Filed: 1983-05-12
Abstract: PURPOSE:To prevent the generation of noise to a signal detection dome from a self-noise or the like incident into a hull-dome from behind by arranging an acoustic window of a signal detection dome, hull-dome, to be non-parallel with the axial direction of a cylindrical signal detection dome transmitter/receiver housed in the hull-dome. CONSTITUTION:An acoustic window 13 of a signal detection dome, hull-dome 11 is formed roughly spherical and a signal detection dome receiver 2 is housed in the hull-dome 11. The transmitter 2 adds waves incident into elements 4 of the transmitter/receiver by the unit of a stave 5 as axial set and displays the results as reception output. Therefore, as the acoustic window 13 is not parallel with the axial direction of the transmitter/receiver 2, reflected waves from the acoustic window 13 enter elements 4 of the same stave 5 in different phases though a self-noise 6 or the like incident into the hull-dome from behind reflects on the acoustic window 13. This prevents the generation of a noise to the signal detection dome from the self-noise 6 or the like from behind to avoid undesired increase in an added value in the stave unit.

Abstract: PURPOSE: To freely adjust the operation stroke by removably inserting multiple pins windable with a wire into pin holes provided on multiple concentric circles of a rotary plate in a thermal actuator rotating the rotary plate via the expansion/shrinkage of shape memory alloy springs and pulling a wire with a pulled load. CONSTITUTION: This thermal actuator is used for opening or closing the ventilating window door of a green house to adjust the temperature in the green house. When the air temperature is high, shape memory alloy springs 10 are kept at the shrunk state because the spring constant of the shape memory alloy springs 10 is high. A wire 12 is pulled via an operation plate 11, a rotary plate 1 is located on the left side of a spindle section 2, a load 16 is pulled by a wire 13, and the window door is opened. When the air temperature is lowered, the shape memory alloy springs 10 are extended by the force of the load 16, the load 16 is lowered as the rotary plate 1 is rotated, and the window door is closed. When pins 7 are reinserted into pin holes 6 on other concentric circles, the winding radius of the wire 13 is changed, and the operation stroke can be adjusted.

Title: Fuel feed control device for internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02D41/10
Filed: 1989-04-04
Abstract: PURPOSE:To correct a fuel feed amount with high precision in proportion to an increase in a demand fuel amount by a method wherein fuel is additionally fed at intervals of a unit time based on a change amount computed by a change amount computing means separately from the feed of main fuel in linkage with rotation of an engine. CONSTITUTION:Based on an engine state amount pertaining to an intake air amount detected by an engine running state detecting means A, demand fuel of an engine is computed by a demand fuel computing means B to feed main fuel. A change amount per a unit time is computed by a change amount computing means C, and based on the computing result, a fuel additional feed control means D additionally feeds fuel at intervals of a unit time based on a change amount separately from main fuel fed in linkage with rotation of an engine. In which case, when the demand fuel computing means B computes a demand fuel amount based on the opening area of a suction system and an engine rotation speed, a weighted average processing means E performs weighted average so as to provide a phase state more progressed by a given time than a change in a demand fuel amount, and computes a change amount. This constitution high-precisely corrects a fuel feed amount in proportion to a change in a demand fuel amount.
