IPC: H01L23/522
Filed: 1986-02-13
Abstract: PURPOSE:To prevent the operation errors caused by wirings by sending signals without being influenced by noise even when minute signals which are easily influenced by a coupling capacity and when signals are sent over the wirings of high impedance condition by enabling the alleviation of a coupling capacity between each two adjacent wirings. CONSTITUTION:A first polysilicon layer 3, a first aluminum layer 72, a second polysilicon layer 5 which is surrounded with a contact window 10 connecting the first polysilicon layer 3 to the first aluminum layer 72, and a second aluminum layer 9 are used as wirings. The potentials of the first polysilicon layer 3, the first aluminum layer 72, and the contact window 10 for connecting the first polysilicon layer 3 to the first aluminum layer 72 are made grounding potentials. Consequently, signals passing through the second polysilicon layer 5 or those passing the second aluminum layer 9 become free from the noise caused by the influence of the signals passing the second aluminum layer 9 or a semiconductor substrate.

Abstract: PROBLEM TO BE SOLVED: To make it possible to surely sort the flower and ornamental plants previously bundled by a prescribed number of pieces each by weights and to recover the flower and ornamental plant bundles sorted by weights without damaging these plants. SOLUTION: The flower and ornamental plants Pa are bundled by 10 pieces each to form the flower and ornamental plant bundles P by a bundling machine 7 of a bundling device A. The weights thereof are measured by a weighing means 15.

A control section 14 drives any of the driving sections 13a to 13c according to the results of the weighing of the weighing means 15. The holding member 12 is then rotated downward and the flower and ornamental plant bundles P are dropped onto the sheets 24 of a first recovering section 20A to third recovering section 20C consisting of trucks.  The sheets descend when the cumulative number of pieces of the flower and ornamental plant bundles P on the sheets increases. When the many flower and ornamental plant bundles P accumulate on the sheets 24, the first recovering section 20A to third recovering section 20C are drawn out and the flower and ornamental plant bundles P on the sheets are recovered.

Title: Failure sensing device for oxygen sensor
Inventor: WATAYA SEISHI
IPC: F02D45/00
Filed: 1991-02-26
Abstract: PURPOSE:To prevent misjudging resulting from the temp. dependency of the response time of oxygen sensor by varying the judging time in compliance with the response time of the oxygen sensor in case failure due to its deterioration is to be judged from the response time when the air-fuel ratio is changed. CONSTITUTION:The temp. of an oxygen sensor 8 to sense the air-fuel ratio of an engine 1 is sensed by a temp. sensor 11. A control device 10 calculates the feedback correction calculation value of air-fuel ratio on the basis of sensing signals of are air flow sensor 4, rotation sensor 9, and oxygen sensor 8. Judgement is made for the condition that the air-fuel ratio goes across the theoretical air-fuel ratio at the specified timing and varies between the lean and the rich. The fuel amount to the engine 1 is controlled on the basis of these conditions. When the air-fuel ratio at the stop of the corrective calculation has varied, judgement is placed that the oxygen sensor 8 goes failure if its response time has exceeded the response time judging value which is varied according to the sensed temp. by the temp. sensor 11.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetostrictive strain sensor that has high accuracy and serviceability and a wide range of applications. SOLUTION: This strain sensor comprises a strain transmission shaft 1 having at least on a portion of its surface a magnetostrictive film 2 made of a magnetostrictive material, a first detecting coil 41 placed in proximity to the part of the strain transmission shaft 1 on which the magnetostrictive film 2 is formed, a second detecting coil 42 placed in proximity to the part of the strain transmission shaft 1 where the magnetostrictive film 2 is not formed, and first and second exciting coils 31, 32 connected in series with each other and placed on the parts of the strain transmission shaft 1 corresponding to the first and second detecting coils 41, 42, respectively, and detects the value of strain applied to the strain transmission shaft 1 as a change in impedance caused by a change in the permeability of the magnetostrictive film 2.  In this case, the parts of the strain transmission shaft 1 facing the second exciting coil 32 and the second detecting coil 42 are made different in diameter from the part of the shaft 1 to which the magnetostrictive film 2 is attached. Consequently, inductance can be selected and hence a temperature drift after differential action becomes so small that the accuracy of the strain sensor is enhanced.
