IPC: G01C17/38
Filed: 1980-05-26
Abstract: PURPOSE:To eliminate the effect of the magnetic field deflection of the moving body itself and accurately measure the advancing direction of the moving body by providing a fixed difference to the sensitivities of magnetic sensors. CONSTITUTION:Magnetic sensors 10, 11 are disposed by mutually perpendicularly intersecting their detection axes 100, 110 and in such a manner that the detection axis 100 alings to the advancing direction of a moving body. If the components of the magnetic fields in the axis 100, 110 directions at the internal point in the moving body are defined as H1A, H1B, respectively and the sensitivities of the sensors 10, 11 as K1, K2 respectively, the outputs VA, VB obtainable from the sensors 10, 11 are VA=K1H1A, VB=K2H1B, respectively. Here, the value of K2/K1 is so set as to compensate the magnetic field deflection in this moving body. Thereby, the effect of the magnetic deflection by the moving body itself is eliminated.

Title: Antifreeze refrigerator
Inventor: SUEYOSHI TORU
IPC: F25D11/00
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain an antifreeze refrigerator where storage period is prolonged by containing a liquid having a freezing point lower than 0 deg.C but not lower than the freezing point of food in a liquid container of good thermal conductor penetrating an upper part of a section for containing foods surrounded by a heat insulating wall and bringing the container into partial contact with chill on the outside of refrigeration chamber section. SOLUTION: Chill being blown into low temperature refrigeration chamber 3b from a cooling duct 5b passes on the outside of the wall 8A of section 8 and flows forward along the outer left side before being collected from an air inlet and returned back to a cooling coil in a refrigerator 2. Since a liquid container 10 penetrates the top part of the section 8 and the upper part of the wall 8A, chill flowing along the upper outside cools a liquid 11 in the liquid container 10. Since the temperature of chill lowers below an intermediate temperature, the liquid 11 begins to freeze and cooling from the outside of the container is spent only for robbing the latent heat of freezing of liquid.  When the operating conditions of refrigerator are set such that the intermediate temperature at a rear point of the section 8 in the low temperature refrigeration chamber 3b will be -1 deg.C or below, antifreeze low temperature refrigeration can be effected with a PG solution having concentration lower than 3.5%.

IPC: F04C28/26
Filed: 1978-06-14
Abstract: PURPOSE: To make it possible to operate continuous capacity control by forming two sealed chambers inside a cylinder and providing a means to produce a counteracting force with respect to a high-pressure oil supply system.  
     CONSTITUTION: Seal ring 17 of piston 3 partitions the inside of a cylinder into chamber 21 and 22. Oil passage 13 is led to a high-pressure oil tank, and oil is caused to flow by a pressure difference. When the pressure in chamber 21 rises, piston 3 moves and pushes spring 18 in chamber 22. Being pushed, spring 18 exerts a force on the side opposite to the direction in which the oil pressure applies. When the forces, including that applies on the end surface of a slide valve, are balanced, the piston moves and capacity control is operated. In releasing control, escape passage 23 is opened and oil is caused to escape to the low pressure side, the slide valve is restored to its former state, and full load operation is performed. Consequently, continuous capacity control can be done easily.

Abstract: PURPOSE:To prevent synthetic resin from flowing out a mold at the time of pressing and molding a continuous molded product of uniform thickness by solidifying a specified section of a sheet before pressing a continuous length synthetic resin sheet in a mold. CONSTITUTION:When a top force 7 is lowered and a press mold 6 is closed, a heated sheet X is fed into a top force main body 5 and a bottom force 8.

The recording elements 7 will do so long as their pitch is sufficiently larger than resolution of the image signal to be transmitted, and, for example, electric field released cold cathode elements which are formed in an array state are used. Then, since a size of an image point and the pitch can be optionally determined by driving only necessary elements in one picture element, gradation recording which is free from correction of dispersion, smoothing, and deterioration in resolution can be carried out.
