Title: Impact tool
Inventor: ARAKI KYOJI
IPC: B25D11/04
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To provide an impact tool eliminating labor in assembly while ensuring stable movement of an impact piece. SOLUTION: In an impact piece 4, a rear end opening 4K as an opening part is formed, a piston 3 is assembled so as to be inserted from this rear end opening 4K. Here in a range of insertion length L4, in accordance with insertion of the piston 3, air in an impact piece space 4S flows out to the outside through a vent hole 5. Thus by making air flow out through the vent hole 5, in the case of inserting the piston 3 in the impact piece space 4S, the piston 3, does not receive an air pressure in the impact piece space 4S. Consequently, the piston 3 can be easily inserted in the impact piece space 4S, and labor is eliminated in assembly. Since the impact piece 4 is made without shortening length of a total unit, stable movement of the impact piece 4 can be ensured in a barrel 2 by the length of the impact piece.

IPC: B29L31/34
Filed: 1987-10-12
Abstract: PURPOSE:To exchange only a cavity section and an ejector pin unit when kinds are changed over, to convey a mold easily and to improve safety by forming the mold in a division type. CONSTITUTION:A cavity section 3a in a top force 1 and a cavity section 4a in a bottom force 2 are faced oppositely and the top force 1 and the bottom force 2 are mold-clamped, cavities 3a', Aa' in the upper and lower cavity sections 3a, 4a are combined, and a resin is injected into the cavities 3a', 4a' and the cavities 3a ', 4a' are resin-sealed. The molds are opened after molding, and a molding resin is ejected from the cavities 3a', 4a' by ejector pin units 7, 8. Since the ejector pin units 7, 8 are fixed to the cavity sections 3a, 4a through springs, the ejector pin units 7, 8 can also be removed by getting rid of only the cavity sections 3a, 4a when kinds are changed over. Accordingly, kinds are changed over simply, and the changeover time is shortened.

Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To recover the toner left in an image carrier and property set the printing density of an image by providing constant current generating means for making the current carried from a toner carrier to toner supplying means constant. SOLUTION: A toner supplying roller 19 is arranged in contact with a developing roller 21.

The toner supplying roller 19 is formed by integrally molding a semiconductor silicone foamed sponge on a core metal, connected to a constant current power source 25 as constant current generating means through the core metal, and a voltage lower than the voltage applied to the developing roller 21 is applied to the toner supplying roller 19 by this power source 25. The constant current control is performed so that the current carried from the developing roller 21 to the toner supplying roller 19 is regularly constant. Thus, the potential difference between the toner carried and the toner supplying means can be stabilized.

For instance, whether the cumulative lighting time of the fluorescent lamps 31 and 32 becomes a prescribed time is decided. Then, every time the cumulative lighting time of the fluorescent lamps 31 and 32 reaches this time, the conversion coefficient group corresponding to the cumulative lighting time of the fluorescent lamps 31 and 32 from among the conversion coefficient groups stored in the RAM 115 is selected and written to the latch of respective coefficient-holding circuits.  As a result, coefficient signals outputted by the respective coefficient-holding circuits are updated, so as to dissolve the aging changes in the spectroscopic characteristics of the fluorescent lamps 31 and 32.

Filed: 1985-11-16
Abstract: PURPOSE:To surely prevent breakdown of a GTO thyristor due to impression of a reverse voltage, by providing a means which breaks the on-gate current of the GTO thyristor upon detecting impression of the reverse voltage. CONSTITUTION:When a regenerative reverse voltage from an electric motor vehicle 4 is impressed across a GTO thyristor 11 under a condition where a switch 13P is closed and an on-gate current is supplied to the thyristor 11 and the reverse voltage exceeds the Zener voltage of a Zener diode ZD, a transistor TR is turned on. When the transistor TR is turned on, an on-output is fetched to a photocoupler PC and a command means in a controller 14 breaks the on-gate current by opening the switch 13P by means of the on-output. Then the GTO thyristor 11 is forced to be turned off by impression of the reverse voltage produced when the on-gate current is broken and stops the reverse voltage under the turned-off condition. Thus an electric power loss caused by a reverse leaking current is eliminated.

IPC: H02P8/12
Filed: 1984-12-07
Abstract: PURPOSE:To reduce power loss by flowing an exciting current from a reverse phase exciting coil when an excitation switch is opened. CONSTITUTION:When a transistor 202 is turned OFF, a current flowed to an A-phase exciting coil 208 at this time continues to flow as it is due to the inductance of the coil, thereby conducting a diode 207. Thus, the current flows in the circuit of the coil 208, a transistor 213, an earth, the diode 207, a B-phase exciting coil 209 and the coil 208. Thus, when the transistor 202 is turned OFF, an exciting current is flowed from the reverse phase exciting coil to reduce power loss.
