Title: Loading device for paper mask
Inventor: TSUJI JUNICHI
IPC: G03B27/58
Filed: 1992-07-03
Abstract: PURPOSE:To prevent the leading end of a paper from entering a mask frame at the time of loading the paper and to prevent the paper from being scratched at the time of inserting a paper mask. CONSTITUTION:1st and 2nd guide boards 35 and 36 are attached on a path for inserting the paper mask 11 in the mask frame 14 so that the boards can be freely moved in the width direction of a color paper 10. When the paper mask 11 is pulled out, the opening of the mask frame 14 is covered with the guide boards 35 and 36. Thus, the color paper 10 can automatically be loaded. When a pressure lever 62b is rotated half, a cam board 63b is slid so as to bring the mask frame 14 downward. Thus, the mask frame 14 is located on a retreat position separated from the color paper 10, so that the leading end of the paper mask is prevented from abutting on the side edge of the paper even in the case of inserting the paper mask 11.

Title: Inductive power coupling with constant voltage output
Inventor: JIYON JIYOOJI BORUGAA
IPC: B60L5/00
Filed: 1987-07-17
Abstract: A constant voltage inductive power coupling for magnetically transferring electrical power from a power source through an air gap to a load comprising a first electromagnetic inductor connected to a power source to generate a shaped alternating magnetic field, a said inductor with a saturable core separated by an air gap from the first inductor and magnetically coupled thereto to receive the shaped magnetic field, the core being responsive to the field to enter a state of magnetic saturation. A coil is electromagnetically coupled to the saturable core and has output leads connected to the load. The magnetic field induced by the first inductor to the second inductor causes voltage in the coil, whose magnitude is determined by the amount of magnetic flux in the core. The saturable core is responsive to any change in input voltage to magnetically counteract such change so as to maintain the core in its state of saturation thereby tending to keep the output voltage constant. The invention is particularly useful in battery charging circuits or for other applications where the voltage required must be kept at a constant level.

Title: Electric junction box
Inventor: KOBAYASHI NOBUFUMI
IPC: F16L3/08
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To provide an electric junction box capable of easily removing a clamp. SOLUTION: In this electric junction box 50, when releasing a lock between a clamp hole 51 and a step-off part 43 of a clamp 10, the lock is released by pressing the front end of one step-off part 43 protruding upward from the surface of a slope 52, using a jig such as a minus screwdriver or the like.

CONSTITUTION:When the vibrator 4 is energized, a vibrating rod 6 is moved vertically and the vibrating tube 3 is also moved vertically. When the pipe 3 is moved downward, a valve plate 8 cannot follow it, a slight clearance is obtained at the upper end 7 of the pipe 3, and the air in the pipe 3 is discharged upward. When the pipe 3 comes to the lower limit, the valve 8 catches up with and a valve sheet 7 is closed. When the pipe 3 rises while the valve inlet of the valve 8 is closed, the air in the pipe is expanded, the pressure in the tank 1 and the pipe 3 is lowered to rise the liquid level in the pipe. The pressure fluctuation is delivered in the gas in the pipe 3, a standing wave of the pressure in the gas or liquid is generated, the fluctuated pressure is large in the part of the valve plate 8 and less at the lower part of the pipe 3. Thus, the gas is discharged upward between the valve plate 8 and the valve sheet 7. The liquid in the pipe 3 is risen by repeating this state.

Filed: 1988-07-18
Abstract: PURPOSE:To enable sure discrimination between a used IC element and a proper new IC element by cutting off the pin end of the IC element in the final process of mounting. CONSTITUTION:An integrated circuit element 10 is mounted on a printed board 20 and is soldered, and then among pins 11 of the integrated circuit element 10, the ends of a part of them are cut off.
