Title: Rectifier employing field effect transistor
Inventor: OOHASHI YASUO
IPC: H02M3/335
Filed: 1978-11-10
Abstract: PURPOSE: To increase efficiency by using field effect transistors as rectifier elements and free Hall elements in rectifiers such as DC-DC converters and the like in order  to minimize losses and to obtain high-speed.  
     CONSTITUTION: A DC-DC converter turns on and off a switching transistor 5, takes out an AC voltage through a transformer 3, rectifies it, smoothes it by a choke 8 and capacitor 9, and supplies power to a load 10. In the rectifier, field effect transistors 6 and 7 are used. The voltage from the transformer 3 is applied to the gate of the transistor 6, and the voltage from the choke 8 is applied to the gate of the transistor 7. In this constitution, since the conducting region is in the linear portion of the drain current of the field effect transistor, the losses in the forward direction are minimized; and since the minority carriers are not related in electric conduction, high-speed operation is possible; thereby the efficiency can be increased.

Title: Muse sound signal processing circuit
Inventor: MORI MASAKAZU
IPC: H04N7/00
Filed: 1991-05-13
Abstract: PURPOSE:To accurately and quickly perform a sound signal processing by always obtaining an optimum threshold level regardless of the convergence operation of a clamp circuit adding a DC component to an input signal. CONSTITUTION:A variable threshold level generation circuit 10 for supplying the threshold level to a MUSE sound signal amplitude discrimination part 9 is controlled by means of a gray level detection signal associated with a clamp circuit 2. The variable threshold level generation circuit 10 supplying the threshold level to the MUSE sound signal amplitude discrimination part 9 is controlled by means of a level error detection signal associated with an AGC circuit 3 and the gray level detection signal associated with the clamp circuit 2. Thus, the optimum threshold level is always supplied to the MUSE sound signal amplitude discrimination part 9 without depending on the convergence of the clamp circuit 2 adding the DC component to the MUSE signal and without depending on the level of the MUSE signal to be inputted and the DC component to be added to the MUSE signal.

Title: Rotary magnetic recording and reproducing device
Inventor: KAWACHI MASANORI
IPC: G11B5/02
Filed: 1990-05-30
Abstract: PURPOSE:To fix a rotary transformer by adhering onto a disk with high reliability by providing a recessed pat including a thread hole for escaping air to a lower face of the disk so as to reduce a pumping pressure generated at screw tightening. CONSTITUTION:A recessed part (groove or chamfer) is provided to a fixing face of a disk 4 for mounting a rotary transformer 9 in order to relax or exclude a pumping action. That is, a spot facing J for air pool is provided to a lower end face B of the disk 4. When a screw 8 is tightened, since the pumping action by the screw 8 is relaxed because he volume is increased more than a volume of a conventional device by the presence of the air pool J, the pumping pressure exerted in the H direction to the rotary transformer 9 is reduced more than that of a conventional device. Thus, even when the screw is tightened after the rotary transformer 9 and the disk 4 are fixed by adhering, the possibility of coming-off of the rotary transformer 9 is precluded and the product with high reliability is realized.

Abstract: PURPOSE:To enable obtaining of a maximum rating combustion quantity even when a feed gas pressure is low and to enable to perform proportional combustion, by controlling a gas pump according to a detecting signal for a load or a pressure. CONSTITUTION:The temperature of hot feed water on the outlet side of a heat exchanger 26 is normally detected by a controller 30 through a signal from a temperature detecting element 28. An electric signal is inputted to a motor 29 from the controller 30 so that a gas pump 22 is run at a maximum rating speed until hot water is heated to about a set temperature, and this enables hot water to be rapidly heated to a desired temperature. When the hot water is decreased in temperature resulting from the increase in the quantity of hot water being fed, the controller 30 increases the operating speed of the gas pump 22 and causes a burner 24 to be increased the combustion quantity, resulting in maintaining the temperature of the hot feed water at the set temperature. This enables reliable obtaining of a maximum rating combustion quantity even when the pressure of a feed gas is low, and allows to perform proportional combustion according to a load so that the temperature of hot feed water is normally maintained at the set temperature.
