Abstract: PURPOSE:To improve the follow-up property of a control system by forecasting a feature command value current by a forecasting means including a required computing element on the basis of a command value current having current and past periodicity and compensating a delay in accordance with the given command value current. CONSTITUTION:Delay elements 9, 10 indicate past command values in-1, in-2 from a current point tn by Td, 2Td respectively. The command values are approx imated as the quadratic equations of a time (t) and the feature specification value in+1=in-2+3(in-in-1) is calculated by the forecasting means 20. For instance, i*c inputted at the present tn is in, the output of the element 9 is in-1, the output of the element 10 is in-2, a subtracted output 11 is in-in-1, a factor output 12 is 3(in-in-1), and the output of an adder 13 is i**c=in-2+3(in-in-1)= in+1, so that a forecasting point at a feature point only by a time Td is indicated. Since the secondary command value i**c is advanced by the Td through the output current ic of the device is delayed by the Td from the command value i*, the ic is not delayed from the i*c.

Title: Indication method of defroster in fridge
Inventor: MIZUNO SHIGEO
IPC: F25D21/02
Filed: 1988-03-08
Abstract: PURPOSE:To prevent an abnormal rise in the indication of temperature in a fridge during defrosting operation so as to avoid user's unnecessary anxiety, by turning off 'defrost' indication after starting a compressor and an indoor fan in sequence after stopping heating by a defrost-heating device by 'defrost completion' signal. CONSTITUTION:In case defrosting operation is carried out at a specified intervals, 'defrost start' signal is issued by a timer, a compressor and an indoor fan are stopped by switching off their electric circuits, and simultaneously the electric circuits for a defrost heater and 'defrost' indication lamp are switched on to start heating and to turn on the indication lamp as well. When the temperature of a cooler rises by heating and a thermostat detects that the temperature reaches a specified one, the electric circuit for the heater is instantly switched off to stop heating. The compressor is started to cool the cooler a few minutes after a timer is actuated by 'defrost completion' signal. A few minutes after the compressor is started, the indoor fan is started to demolish local high temperature around the cooler by agitating the air in the fridge. Therefore, the temperature in the fridge indicated on an indicator begins to fall from this time. About one minute after the indoor fan is started, 'defrost' indication lamp is turned off.

CONSTITUTION:The phase of the single color coherent laser beam L1, to be emitted from an excimer laser device 3, is rotated at an angle of 90 degrees by a lambda/4 wavelength plate 4, the laser beam advances 90 degrees, it is turned into a circular polarized light L2, it comes into a mask 7 passing through a reflecting mirror 5 and an eye-glass 6, then the laser beam is made incident on a wafer 11 after passing through a trapezoid mirror 8, a concave mirror 9 and a convex mirror 10, the resist 1 on a semiconductor substrate 2 is exposed, and a pattern determined by a mask 7 is developed. The phase of the circularly polarized light projected on the resist 1 is changed by the reflection of the substrate 2, but as it is reflected as a circularly polarized light, it shows no standing wave effect in the resist 1. When a homogenous light is made to irradiate, the maximum value and the minimum value are revealed in odd multiplication and even multiplication of 1/4 wavelength, but if it is a circularly polarized light, one of them becomes the polarized beam which is shifted by a 1/4 wavelength from the other light, and as a result, one of them shows a maximum value, the other one shows a minimum value, and a fixed value, having the valanced intensity of the minimum and the maximum values can be obtained at all times.
