Title: Magnetic circuit of speaker
Inventor: YASHIMA OSAMU
IPC: H04R9/02
Filed: 1982-05-27
Abstract: PURPOSE:To reduce easily the current distortion due to the non-linearity of the permeability of a magnetic circuit, by forming a coating layer made of metallic materials on the side of a permanent magnet by means of plasma metallizing. CONSTITUTION:A coating layer 6 formed by using metallic materials such as copper and aluminum by means of plasma metallizing is formed in one process on the internal surface of a cylindrical permanent magnet 2 by means of the plasma coating. Since the coating layer 6 is formed on the internal surface of the cylindrical permanent magnet 2, a voice coil 4 generates almost no current distortion so that driving force proportional to voice voltage is obtained. In this case, it is sufficient, if the coating layer 6 is the one which works as the secondary winding of a voice coil. The below figure shows the case where the coating is applied to a magnetic circuit for a dynamic speaker of inside magnetic type. A coating layer 10 is formed on the external surface of a cylindrical permanent magnet by using metallic materials such as copper and aluminum by means of plasma metallizing.

IPC: H02M1/00
Filed: 1991-04-22
Abstract: PURPOSE:To quickly detect a lamp voltage of a discharge lamp. CONSTITUTION:One end of a discharge lamp DL is connected to a connecting point of switching elements Q1, Q2 via an inductor L1, the other end of the discharge lamp DL is connected to a connecting point of switching elements Q3, Q4 via an inductor L2 having an inductance value almost equal to that of the inductor L1, and a capacitor C0 is connected in parallel with the discharge lamp DL. Moreover, a voltage detecting means (not illustrated) for detecting voltages VA, VB across the discharge lamp DL is also provided. Thereby, the voltage across the discharge lamp DL is not varied due to high frequency switching operation of the switching elements Q1 to Q4. Accordingly, an integration circuit for controlling voltage variation is no longer required and delay of detection by integration can be eliminated. As a result, a lamp voltage of the discharge lamp DL can be detected quickly and ON-OFF states of the first to fourth switching elements Q1 to Q4 can be controlled depending on the condition change of the discharge lamp DL.

Abstract: PURPOSE:To prevent rapid rising of dew point, melting, etc., by previously adding water in a quantity equivalent to the quantity of water to be evaporated from a wet coating layer at the head part of a photosensitive material to air in a drier zone. CONSTITUTION:Air used in a previous cycle is sent to a ventilating apparatus 2 through a supplying pipeline 1a after water is removed from the air by leading the air to a dehumidifier 9. The air blown to an air blowing pipeline 1b from the ventilating apparatus 2 is led to an air conditioning apparatus AC provided with a cooling part 3, a heating part 4, and a humidifying part 5. Moreover, the dried air is sent to an initial drying chamber 6 in a drier zone DZ from an outlet pipeline 1c. At that time, steam is sprayed to a humidifying part 5 by driving a control valve 11a of a head part countermeasure spray apparatus 11 and excess water in quantity equivalent to the quantity of water to be evaporated is previously added to air to be sent to the initial drying chamber 6. The dew point is thus prevented from rising abruptly at the time when the head part of a web W having a not dried coating layer breaks into the initial drying chamber 6.
