Abstract: PROBLEM TO BE SOLVED: To contrive the highly precise adjustment of a resistance value in the laser-trimming method for a thick-film resistor. SOLUTION: A thick-film resistor 7 is formed in the state, wherein the opposing electrode conductors 2 are completely contained, and the electrode conductors 2 are connected. At this time, the density of the flow 10 of the second current becomes lower than the density of the flow 9 of the first current. Accordingly, a laser-trimming region 8 becomes the region having the ratio relating to the resistance value, and the desired resistance value can be adjusted in a highly precise manner by trimming the region.

Abstract: PURPOSE:To simplify a driving circuit by performing the opening and closing of cold air inflow by driving a DC motor by switching on/off first and second FETs to rotate a rotor having blades provided in a housing. CONSTITUTION:A title device includes outlets 12 communicating with a cold air inlet 11 provided on the same flat plane in a square housing 10, two openings 13 having angular difference of about 120 deg. between the inlet 11 and the outlet 12, and a hollow cylindrical protruded portion 14 formed in the center of the housing 10. A DC motor 15 is driven by first and second FETs 34, 35. Since the openings 13 are opened and closed by three blade parts 19 mounted at an angle of about 120 deg. on the substantially cylindrical protruded portion 14 mounted and adapted to be rotatable by the DC motor 15, there is no need of providing on a duct panel 32 a displacement margin space in the blow-off direction of cold air, and hence a refrigerator effective utilization volume can be increased.

Abstract: PURPOSE:To ensure highly accurate control by detecting the degree of opening of an opening/closing plate and successively setting the opening of the opening/ closing plate to an arbitrary one in response to a temperature difference between actual temperature and set target temperature by providing driving means for receiving signals from comparison means and position determination means and issuing a signal to a motor. CONSTITUTION:Warehouse temperature T1 from a warehouse temperature detection means 62 and target temperature T2 from warehouse temperature setting means 63 are inputted, respectively. A target resistance R1 between brushes A60g and B60h corresponding to the degree of the opening of an opening/closing plate is determined, which target resistance R1 is then inputted as a signal into driving means 66. A present resistance R2 between the brushes A60g and B60h is inputted as a signal S5 into the position determination means 65 by position detection means 60, and is inputted as a signal into a driving circuit 66 by the position determination means 65. The target resistance R1 and the present resistance R2 are compared, it is judged on the basis of a detected resistance value whether the resistor is broken down or is opened.

Abstract: PURPOSE:To reduce the frequency of defrosting in business hours and prevent the increase of a temperature in a showcase and the like by a method wherein defrosting periods are set differently in day time and night time by a defrosting period determining means and an accumulating timer in accordance with the opening times of a door and switching operation is effected automatically. CONSTITUTION:A defrosting period determining means 32, inputting the signals of an accumulating timer 31 and a defrosting mode determining means 29, are provided whereby the defrosting periods of day time and night time may be switched by a first switch 24 and a second switch 25. When defrosting operation at night is determined once by the first switch 24 through a first timer 27 and a second timer 28, defrosting operation may be effected every days at the same time. Further, the opening period of time of a door is counted by the accumulating timer 31 in day time and the defrosting time period (t14) at night may be changed arbitrarily by the time (t12) and defrosting may be effected concentrically at night in accordance with the door opening time of day time. According to this method, defrosting frequency in the day time can be reduced and the increase of the inside temperature of a showcase and the like may be prevented.

Abstract: PURPOSE:To obtain a temperature controller which does not change a load at the time of setting a target, by providing a target temperature setting means which sets the target temperature. CONSTITUTION:Signals from a temperature setting means 10, to which signals from a push switch 7 which sets the target temperature and a variable resistor 8 are inputted, and a temperature detector 9 which detects an input temperature are inputted to a temperature control means 11. The signal from the temperature control means 11 is inputted to a load control means 12, and the signal from the load control means 12 is outputted to a load 13. Then, the load for temperature setting is kept in the state before temperature setting. Thus, the temperature controller is obtained which does not change the load at the time of setting the target.
