Title: Cooling device for internal combustion engine
Inventor: NODA KOJI
IPC: F01P7/16
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To control the flow of cooling water on the cylinder block side according to the temperature of cooling water without needing a control means from the outside. SOLUTION: A radiator 15 is interposed in a main cooling water passage 14 between a first cooling water outlet 12 and a main cooling water inlet 11 of a water jacket 4 on the cylinder head side, and a by-pass passage 17 branching off from this part is connected to a second cooling water outlet 13. A cooling water inlet 7 and a cooling water outlet 8 are in positions where pressure drop caused by the outflow of cooling water from the second cooling water outlet 13 acts almost equally, and the first cooling water outlet 12 is close to the cooling water outlet 8. When a passage control valve 18 is on the bypass passage 17 side at the time of low temperature, pressure difference is not generated to the cooling water inlet 7 and cooling water outlet 8, so that the flow of cooling water on the cylinder block 1 side stops.  When the temperature becomes high and cooling water flows out of the first cooling water outlet 12, pressure difference is generated to the cooling water inlet 7 and cooling water outlet 8, and cooling water flows.

IPC: G01L1/00
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To provide highly reliable strain data through strain gauge measurements using a resistance wire strain gauge as a sensor by correcting the resistance of the resistance wire of the strain gauge, which changes on detection of the expansion or contraction of a structure and which is then changed by the influence of temperature. using methods reflecting the principles of those changes. SOLUTION: When a strain gauge is connected to one side of a Wheatstone bridge circuit, the resistance value of a lead wire added to the resistance value of the strain gauge is corrected, and the initial value of an active gauge is corrected by means of the rate of change of resistance by which the resistance value of the active gauge changed by the influence of a temperature change is obtained on the basis of the initial value of a dummy gauge. One is subtracted from the square of the resistance value of the active gauge under load divided by the initial value, and the result is obtained as strain.

IPC: G02F1/1335
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device whose visual field angle is wide and which can be produced in a high yield. SOLUTION: Liquid crystal 20 is sealed between the first substrate 10 and the second substrate 16, which are oppositely arranged. First electrodes 12 are formed at prescribed positions of a prescribed area on the first substrate 10 and second electrodes 18 are formed at positions shifted with respect to the first electrodes 12 of the prescribed area on the substrate 16.
