Title: Displacement detector
Inventor: NIWA HIDEO
IPC: G01B7/00
Filed: 1990-05-17
Abstract: PURPOSE:To obtain a signal with superior linearity for displacement by generating magnetic flux distributed between a pair of yokes in the longitudinal direction of the yoke at equal interval, and displacing a detection coil inserted to the yoke on one side. CONSTITUTION:The yoke 1 is formed in columnar shape and the yoke 2 in cylindrical shape, and they are arranged in a coaxial state so as to be in parallel with the longitudinal direction. A magnetic flux supply means 3 is comprised of a side plate 4 and an excitation coil 5, and supplies the magnetic flux to each one terminal in the longitudinal direction which forms the same side at the yokes 1, 2. The detection coil 7 is inserted movably to the yoke 1 in the longitudinal direction, and is linked to a mobile body which detects the displacement by a linking means 8 made of nonmagnetic material or nonmetallic material. The magnetic flux distributed in the longitudinal direction between the yokes 1, 2 is generated at equal interval, and the signals in accordance with the number of yokes interlinking with the magnetic flux can be obtained. Since the number of interlinking magnetic flux is changed linearly according to the displacement of the detection coil in the longitudinal direction of the yoke 1, the signal is changed linearly according to the displacement of the detection coil 7.

Filed: 1991-05-31
Abstract: PURPOSE:To reduce power consumption necessary for temperature control compared with conventional ones with regard to the container-inside temperature control method of a vending machine which is disposed an evaporator connected with a heater or a refrigeration cycle in its container. CONSTITUTION:The number of remaining sale products are judged at a step (a-17) in a heating processing routine. When the remaining number of the sale products are small, the number of the revolutions of a fan is turned smaller at a step (a-18) so as to reduce the range of the forced circulation of the air in the container and heat exchange quantity is reduced so as to prolong the off period of the heater so that power consumption is reduced. Furthermore, the number of the past day from the last filling-up is judged at a step (a-20). Only when the number of the remaining sales products is large in spite of passing the prescribed number of days, the number of the revolutions of the fan is turned smaller at the step (a-18) so as to automatically reduce the range of the forced circulation of the air in the container and the products in poor demand are not all heated but only part of them are heated so as to prolong the off period of the heater so that power consumption is reduced.

Title: Memory type (polymer/liquid crystal) composite film and method of optical switching using the same
Inventor: CHON FAN KYON
IPC: G02F1/13
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To obtain a new optical switching technique at a low cost which can be applied for an optical shutter or a display device and which is easily operated. SOLUTION: A composite film consisting of a polymer phase 3 having a three- dimensional mesh structure and a liquid crystal which forms a continuous phase in the polymer phase is prepared. The composite film has a phase separation structure in which the polymer phase 3 and the liquid crystal phase 4 are aligned almost parallel to the direction of the electric field, and a polymer thin layer is formed on the surface. By using an optical element produced by holding the aforementioned composite film as a light-controlling layer 11 between electrode substrates 1, optical switching with the following processes is possible.  In the optical switching operation, a light-scattering state with no electric field applied can be changed into a light-transmitting state by applying a pulsed electric field between electrode layers, the light-transmitting state is recorded in a memory by opening electrode layers without forming a short circuit between the electrode layers, and then if necessary, the state is changed into a light scattering state by forming a short circuit between electrode layers. Since no electric field is required to maintain the light-transmitting state, the power consumption is extremely reduced.

Abstract: PURPOSE:To realize an excellent control performance even for a control object of large static friction by comparing a signal related to the controlled variable of the control object with a prescribed threshold value and switching the inference system for linearity and that for nonlinearity based on the result of this comparison. CONSTITUTION:A program P1 to prescribe the inference system for linearity and a program P2 to prescribe the inference system for nonlinearity are incorporated in an observer 10, and a comparing part 10A which compares the signal related to a controlled variable (y), for example, its differential value (velocity) with a preliminarily determined threshold is incorporated also. The signal related to the controlled variable of the control object is compared with the prescribed threshold, and the inference system for linearity and that for nonlinearity are switched based on the result of this comparison, and the state in the linear or nonlinear operation of the control object is inferred. Thus, an inference value is first kept constant at the time of operation state and normal linear inference is performed hereafter in a system having a high coefficient of static friction, thereby rationalizing the inferred quantity.
