Title: Alternating current control unit
Inventor: MUKAI KUNIAKI
IPC: G05F1/45
Filed: 1978-10-17
Abstract: PURPOSE: To realize the steady control for the AC current in a high response by switching the current gain to the proper value with every cycle based on the firing angle of the preceding cycle and the load force factor measured at the beginning of conduction, and carrying out the correction for the firing angle with every cycle.  
     CONSTITUTION: Firing angle α of the preceding cycle which is the output of firing angle memory part 24 is supplied to address calculation part 25 along with load force factor ϕ given from load force factor detection part 23, and current gain f (α, ϕ) is delivered from DC gain correction part 27 via table memory part 26. At the same time, firing angle increment Δα is calculated at arithmetic part 13 based on current deviation ΔI, current gain f (α, ϕ) and effective current I 90  of the 90° firing angle time. After this, Δα given from part 13 is added to firing angle α of the preceding cycle at firing pulse generation part 14 to obtain a new firing angle. In such way, current deviation ΔI is converted into the firing angle correction amount based on current gain f (α, ϕ) to obtain the firing angle. Thus the load current can be approximated quickly to the set value in a steady way.

Abstract: PURPOSE:To provide an electronic cash register capable of saving the handling time of a change processing by update-recording or cumulatively recording a calculated change amount in a change balance recording medium. CONSTITUTION:When a change card is inputted to a card reader 6, the balance of the change card is read and whether or not the balance is more than a total sales amount is discriminated. When the balance of the change card is less than the total sales amount, an operator receives cash from a customer and inputs a deposit amount. The change is calculated and displayed at a display device 3 and whether or not the change is less than a prescribed amount is discriminated. When the change is more than the prescribed amount, the change is handed over, and when the change is less than the prescribed amount, the change amount at the time is cumulatively recorded to the balance of the change card by the card reader 6. On the other hand, when the balance of the change card is more than the total sales amount, the total sales amount is subtracted from the balance of the change card and the balance of the card is updated and settled. When the change card is not inputted to the card reader 6, the change is handed over as usual.

Inventor: MIYAZAKI HARUHITO
IPC: F24F3/14
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a dehumidifier capable of improving the dehumidifying capacity of a main body as a result of improving the regeneration efficiency of a dehumidifying part. SOLUTION: A dehumidifying rotor 5 is mounted to a flange part 42 by providing a gap (D) between the surface of the dehumidifying rotor 5 and the tip part of the flange part 42 so that the dehumidifying rotor 5 may be rotated smoothly. And the width (E) of the flange part 42 is formed in the size larger by several times of the gap (D). Therefore, the resistance in the case when regenerated air flows in the direction leaking outside is large, and the regenerated air entered into the gap is bent to the air blowing direction and blown toward the dehumidifying rotor 5.  That is, the quantity of the regenerated air leaked outside from the gap is remarkably reduced and a large quantity of the regenerated air can be effectively passed through the dehumidifying rotor 5, therefore the regenerated effectiveness of the dehumidifying rotor 5 can be remarkably increased, and the trouble such as deterioration of the dehumidifying capacity of the main body is not caused.
