Title: Protective device for power circuit in servomotor driving controller
Inventor: OKUYAMA JUNICHI
IPC: B60R16/04
Filed: 1993-03-30
Abstract: PURPOSE:To prevent the damage on a power circuit positively even when the power circuit side terminal of a motor rotational-quantity detecting means is grounded while surely operating an electronic control circuit, and to eliminate the need for excess operation at low cost. CONSTITUTION:When a terminal T1 is grounded, currents I0 flowing from a power circuit 10 reach the allowable currents or less of the power circuit 10 by a resistor R1 15. Consequently, even when the terminal T1 is grounded, the power circuit 10 is not damaged. The supply voltage of a control circuit 14 and an external electronic control circuit such as another IC, etc., is ensured at the voltage of minimum requirement. Accordingly, the control circuit 14 and the external electronic control circuit can be operated positively. The voltage Vp of a terminal T3 lowers to approximately zero by the grounding of the terminal T1, and a Vp voltage abnormality detector 17 turns a TR1 16 off when the detector 17 detects lowering to approximately zero. As a result, the supply voltage of the control circuit 14 and the external electronic control circuit is held at voltage set in the power circuit 10, and the control circuit 14 and the external electronic control circuit can further be worked more surely.

Title: Image-forming device
Inventor: MATSUNAGA TAKESHI
IPC: G03G21/16
Filed: 1994-03-15
Abstract: PURPOSE:To provide an image-forming device which obtains an open space sufficiently for jammed paper removal and part replacement and is satisfactory in terms of operability. CONSTITUTION:When an upper frame 1 is closed, a hook 18 strikes against a lock part 14, and the front end of the hook 18 turns around a hook shaft 14 toward a side wall 14a, slides down along the side wall 14a and is inserted into a lock hole 14b. By the insertion of the front end of the hook 18 into the lock hole 14b, the hook 18 turns clockwise around a hook shaft 17 while being pulled by a hook spring 19, and an actuator 15 is caused to turn counterclockwise around a swing shaft 15a by means of a swing spring 16 fixed to the hook shaft 17, so that a projection 15c depresses an interlock switch 13. The switch 13 is not turned on unless the part of the overlap of the upper frame l and lower frame 2 is at least securely closed. Therefore, because it is not necessary to provide an overlap part between the upper and lower frames, the open area is generously taken, and workability and operability improve.

Title: Oil seal
Inventor: ASAKA URATAROU
IPC: F16J15/32
Filed: 1982-04-28
Abstract: PURPOSE:To minimize rotational resistance, by providing a communication bore in an annular lip that communicates on the lubricating oil side with a hollow section thereby imparting to the hollow section the negative pressure that will be resulting from the flow of the lubricating oil due to the centrifugal force caused by rotation of a rotating shaft to be sealed. CONSTITUTION:When a rotating shaft 2 is in rotation, and lubricating oil is forced to flow due to the centrifugal force of the rotating shaft 2 along the slant 5b with an angle beta as shown by an arrow (b) so that a negative pressure state is created at a corner 11, the pressure in the hollow section 17 in communication with the negatively pressured corner 11 becomes negative. Then, the annular lip section 5 receives a force radially outward of the rotating shaft in accordance with its pressure difference, and since a second waist part 16 is thin to have a diaphragm function, the second waist port 16 is bent outward in accordance with the pressure difference between the pressures outside and inside the hollow section 17, which overcomes the strain in the annular lip section 5 so that a very fine gap is formed between a contact section 5c and the outer circumference of the rotating shaft 2. Accordingly, the frictional resistance between the annular lip 5 and the rotating shaft 2 can be reduced.

Title: Gas laser device
Inventor: ITO SHINJI
IPC: H01S3/097
Filed: 1989-03-23
Abstract: PURPOSE:To keep a glow discharge uniform for a long time by outputting a control signal to a gas supply device to realize a constant amount of light absorption through a gas in a cell connected to a laser tube. CONSTITUTION:A control signal is output to a gas supply device 2 to realize a constant amount of light absorption through a gas in a cell 3 which is connected to a laser tube 1. Since a gas containing a halogen element is a diatomic molecule, it has a vibration level and absorbs infrared light whose wavelength is synchronized with the level; therefore, an amount of infrared rays through laser gas is proportional to a concentration of the halogen gas in the laser gas. A supplement amount of the halogen element to the laser gas is thereby controlled to keep the absorption amount of infrared rays constant, whose wavelength corresponds to a vibration level of a gas molecule containing the halogen element. Thereby, it is possible to keep a glow discharge uniform for a long time for laser excitation.
