Title: Push-pull type of switching power unit
Inventor: SASAKI JUNICHI
IPC: H02M7/12
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To improve with simple constitution the power factor by widening the continuity angle of the input current of a push-pull type of switching power unit and suppressing the peak currents. SOLUTION: Although a switching control circuit 5 outputs drive pulses DP1 and DP2 with the same pulse width, which are slid by a half cycle from each other, to transistors Q1 and Q2 to switch them alternately, the pulse width is widened by more than a half cycle so as to furnish the period when the transistors turn on at the same time. The power inputted into the middle tap of the primary winding N1 of the main transformer Tm charges a capacitor C2 through the main transformer Tm during the period, when either one side of the transistors Q1 and Q2 is on, and excites a flyback transformer Tf, being applied to the primary winding Nf1, during the period when they are simultaneously on, but the excitation energy charges the capacitor C1 through a diode D1 from the secondary winding NF2, being converted into currents during the next period when the one side is on.  While the rectified voltage of a diode bridge 4 is low, the power is supplied from the capacitor C1.

Title: Head plate shifting mechanism of tape recorder
Inventor: TAKAI KAZUKI
IPC: G11B15/10
Filed: 1979-12-18
Abstract: PURPOSE: To enhance the controllability of a tape recorder, by advancing and retreating the head plate by making use of the rotating force of a motor and cancelling the lock of the spring force respectively.  
     CONSTITUTION: Both the minor gear 5a and the coupling gear 6 are turned by the flywheel 5 which is turned by the motor 21. The gear lock bar 2 is turned in the direction of the arrow (b) with the sliding of the slide bar 1 toward the arrow (a) during the loading of a tape pack and others, and thus the rotary plate 40 and the rotary gear 4 are turned clockwise. As a result, the partial notch 4a is shifted to secure an engagement between the minor gear part 6a and the rotary gear 4, and the lock bar 7, i.e., the head plate 10 is moved forward against the force of the spring 19. The plate 10 is held at the position of reproduction by an engagement of the pin 72 to the locking stage part 82. The electric conduction is broken to the adsorbing plunger 9 during the quick winding or the rewinding, and accordingly the lock is cancelled between the shift plate 8 and the pin 72. As a result, the head plate 10 is retreated.

Title: Transfer-material carrying device
Inventor: SAWADA TAKAMASA
IPC: G03G15/02
Filed: 1980-11-20
Abstract: PURPOSE:To perform excellent transfer by preventing the disorder of a picture due to an external electric field, by providing a couple of carrying members, which sandwich and carry transfer material to an image carrier transfer position, with the surface of a charging system member which charges both the surfaces of the transfer material by friction with the opposite polarities. CONSTITUTION:A couple of rollers 13a and 13b sandwich and carry a transfer material to an image carrier transfer position; and the driving member 13a is a rubber roller and has a negative frictional charging sequence, and the other driving member 13b is an aluminum roller and has a frictional charging sequence held positive to paper. Therefore, the surface of the transfer material is charged by friction with the negative (minus) polarity. The reverse surface of the transfer material, on the other hand, is charged by the rubber roller with the opposite, i.e., positive (plus) polarity, and consequently both the surfaces differ in polarity from each other. Thus, charges on both the surfaces form an internal electric field including the transfer material, so that any substantially evil influence is not exerted on the outside.

IPC: H04L47/20
Filed: 1991-07-04
Abstract: PURPOSE:To accurately discriminate the number of arrival contracted cells by counting the number of cells arriving between reference interval cells sent from a terminal. CONSTITUTION:In a terminal 1, a reference interval is indicated to information cells to select a preliminarily contracted number of information cells from a reference interval report cell generating means in accordance with the reference interval signal set by a reference interval time generating means 3. Cells from plural terminals are multiplexed by a multiplexing part 4 and are inputted to an ATM exchange, and the number of cells arriving in the reference interval is counted by a reference interval cell counting and discriminating means 6. When the counted value exceeds the contracted number, a control output is generated. Thus, an average value is checked without an influence of fluctuation of cells by the number of reference interval report cells in a certain time to accurately polish the flow rate of cells from terminals.

Inventor: KONNO ISAO
IPC: F23N1/00
Filed: 1985-07-26
Abstract: PURPOSE:To make it possible to control most adequately flow rates from low to high with one flow control device by controlling the fluid pressure in front of a flow control valve on flow control instruction, lowering the fluid pressure in front of the valve in the low flow rate range, and making the opening of the flow control valve larger. CONSTITUTION:With the control on automatic control mode, the fuel requirement instruction value which is outputted from a boiler master signal 1 which gives the instruction for fuel requirement and air volume requirement signal outputted from the main steam flow rate signal and the actual fuel volume signal are compared in a comparator 2, and its output is inputted to a flow regulator 3. The output of the regulator 3 is added to the signal of pressure control in front of the flow rate valve by an adder 5 through an automatic/ manual changeover device 4, and its output signal is inputted to the flow- regulating valve 6 to control its opening. Accordingly the lowering of the pressure in front of the valve in the low flow rate range makes larger the opening of the flow-regulating valve and makes it possible to control in the low flow rate range. With this arrangement a wide range of flow rates from low to high can be controlled most adequately.
