Title: Ringing choke converter of synchronous rectification system
Inventor: SATO MORIO
IPC: H02M3/338
Filed: 1995-05-19
Abstract: PURPOSE: To obtain a ringing choke converter by which a resistance value in an on- period is reduced and whose efficiency is improved by a method wherein the width of a pulse applied across the gate and the source of a MOSFET is controlled by a resistance, a saturable inductor and a reset-signal control circuit. CONSTITUTION: A reset-signal control circuit 15 detects an output voltage. When it is higher than a set value, a current which is output from a diode 15f is made large, and, when it is low, the current is made small. In addition, the current which is output from the diode 15f is passed through a saturable inductor 17 when the voltage of an auxiliary winding 11c is changed to a direction in which a MOSFET 14 is reverse- biased. It flows through a resistance 16, the auxiliary winding 11c and a secondary winding 11b so as to reset the saturable inductor 17. Then, when a reset current is large, the time elapsed until the saturable inductor 17 is saturated becomes long when the voltage of the auxiliary winding 11c is changed in a direction in which the MOSFET 14 is forward-biased, and the on-period of the MOSFET 14 becomes long.  As a result, it is possible to obtain a ringing choke converter in which an output voltage is kept constant and whose efficiency can be improved.

Title: Recording paper winding device
Inventor: TOTSUKA YUKITAKA
IPC: B41J15/16
Filed: 1989-06-20
Abstract: PURPOSE:To make it possible to attach and supply recording paper to a main printer system easily and minimize an occupancy space by enabling a winding part for taking up the recording paper to move to the printer. CONSTITUTION:If recording paper 5 is attached to a main printer system 2, a clamp lever for clamping a support 10 to a base 3 is disconnected, and sliding rails 9a, 9b, 9c are drawn out in two stages by pressing a winding device 1. This results in a winding part 4 being moved to an area outside the main printer system 2. Consequently, a recording paper insertion part above the main printer system 2 can be opened, then recording paper can be easily attached to an area inside the main printer system 2 and can be drawn out to a space above the main printer system 2. In this case, the winding device 1 moves guided by the sliding rail 9, so that the device 1 is placed at the same location as when it is initially positioned in relation to the main printer system 2. As a result, recoding paper does not run obliquely. In addition, the device can be miniaturized and transported easily because the winding device 1 is located in the occupancy area of the main printer system 2, except the time when the recording paper is replaced.

Title: Data output device of camera accessory
Inventor: NAKAI MASAAKI
IPC: G03B7/20
Filed: 1982-09-09
Abstract: PURPOSE:To reduce the number of signal terminals, by designating selectively an address by the setting operation to a fixed storage means of an accessory and by data from a camera body, to transfer variable data and fixed data from the fixed storage means to the body. CONSTITUTION:An address designating signal of an ROM in a data output part 7 on the lens LE side is outputted in series from a circuit IF of the body through terminals JB2 and JL2, and fixed data is sent in series from the output part 7 to the circuit IF through terminals JL2 and JB2. When this transfer is completed, data from information output devices DS and FS on the lens side are used as an address signal to designate an address of the ROM, and information is transferred to the circuit IF in series. When the data transfer from the lens is completed, the circuit IF sets a terminal, which is connected to a terminal i3 of a microcomputer 1, to ''H'' to stop the lens data reading operation. Thus, one terminal is used as the terminal for transmitting fixed data as well as the terminal for transmitting variable, namely, set data to reduce the number of terminals.

IPC: F26B17/26
Filed: 1977-12-29
Abstract: PURPOSE: Ballast material is transported while it is shaken and sirred, and by applying far-infrared rays to it while it is being transported, it is efficiently dried.  
     CONSTITUTION: By applying electricity to electromagnetic coil 14, tortional vibration is given to moving truck 3. Here, when ballast material is supplied to bottom center 2, the ballast material, while receiving radiation L from far-infrared ray radiator 30 and also receiving vibration in the circumferential direction, is transported. Finally, the ballast material reaches shutter 4, and here the ballast material is caused to fall on bottom center 2 or truck 3 below. Then it slowly moves upward on truck 3. In this way, the ballast material is moved on truck 3 while receiving vibration, and it receives constantly radiation L from far-infrared radiator 30 while it is being stirred. Thus, it absorbs thermal energy, and is heated and dried.
