Title: Measuring apparatus of toe of automobile
Inventor: SAKAMOTO TOSHIHARU
IPC: G01B21/26
Filed: 1987-10-28
Abstract: PURPOSE:To compute the changing amount of the toe of a wheel highly accurately, by providing a contact plate, whose surface is in contact with the side surface of the wheel of an automobile, and providing a supporting means, which is connected to the contact plate and supports the plate so that the plate can be turned in the changing directions of the contact plate and the wheel. CONSTITUTION:A surface 2a of a contact plate 2 is brought into contact with the side surface part of a wheel 10. The contact plate 2 is connected to a supporting means 4 and supported so that the plate can be turned in the changing direction of the toe of the wheel 10. When a pair of contact pins 22 and 24 are operated normally, both contact pins 22 and 24 computed the turning angle theta, i.e., the changing amount of the toe of the wheel 10 by using the data of the displacement amounts of both pins. When either of a pair of the contact pins 22 and 24 is not operated normally, the changing amount of the toe of the wheel is computed by using only the data of the displacement amount of the contact pins, which is pushed with the contact plate 2. Therefore, the error due to the returning error of the contact pins is not included in the data of the changing amount of the toe. Thus, the changing amount of the toe of the wheel 10 can be computed highly accurately.

Title: Speed controller for coolant recirculation pump
Inventor: KAGEYAMA TAKAO
IPC: G21D3/04
Filed: 1990-10-12
Abstract: PURPOSE:To prevent long lasting of reactor power oscillation by increasing recirculation pump speed in accordance with the decrease of supply water temperature from the steady state in the case that operation point is in the vicinity region of a reactor power oscillation limit. CONSTITUTION:This operation point is on the stability limit line and here,the withdrawal of control rod 3a and the speed reduction of coolant recirculation pump 6 are protected. In this situation, the reactor operation point A moves to point C' owing to the core flow increase and the supply water temperature decrease. If a loss of supply water heating occurs at the point A, the neutron flux variation at the point B to be shifted without the present device should be more continuous than at the point A to last for more than 10 s. On the contrary at the point C', the transient will be stabilized in ca. 7 sec. Thus, the use of this device can prevent the long lasting of reactor power oscillation state caused by the disturbance of reactivity.

Abstract: PROBLEM TO BE SOLVED: To detect display defects of a liquid crystal panel due to organic contamination in a short time which can not conventionally detected unless ageing by energizing for a long time is carried out, and to easily find and control organic contamination in an early stage by providing a heating means to blow hot air at a predetermined temperature to a liquid crystal image display device and carrying out image inspection in a high temperature operation state. SOLUTION: A liquid crystal panel 1 is inspected while a glass plate 46 heated by a heating device 45 such as a hot plate is in contact with the upper or lower face of the liquid crystal panel 1. The heating temperature depends on the degree of organic contamination, but preferable result is obtained at 60 to 80 deg.C. The contact time is at least 10 sec or longer, and if it is less than 10 sec, the temperature of the liquid crystal panel can not be stabilized. The inspection method to bring the heated glass substrate 46 into contact with the liquid crystal panel 1 enables accurate inspection because uniformity of heating is easily obtained, however, the method has a drawback of rather complicated mechanism. As for an easy heating method, for example, hot air 48 may be blown to the liquid crystal panel 1 by a dryer 47 or the like.
