The memory card can be easily reset in terms of software without controlling power supply in terms of hardware. Also, the memory card can be smoothly attached and detached during insertion of the memory card into a socket and reduce damage to a device.

A developing unit has a voltage-applicator (80) to apply a developing bias voltage to a developing roller (72). The voltage-applicator (80) applies the developing bias voltage for a first duration to apply an AC voltage having a rectangular waveform, and a second duration to stop applying the AC voltage. The AC voltage has a duty ratio of 50% or more in a direction for causing toner to develop an electrostatic latent image. The number of cycles of the AC voltage in the first duration is two or more, and the AC voltage has a voltage in a direction for pulling the toner back to the developing roller, just before transition to the second duration. The developing unit suppresses occurrence of image unevenness due to a fluctuation in developing gap. Thus, an image forming apparatus equipped with the developing unit forms a high-quality image while suppressing image unevenness.

A ball screw device includes a screw engaged into a nut member for forming an endless ball guiding passage between the nut member and the screw and for receiving a number of ball bearing members, a ball return pipe includes a U-shaped structure having a central tubular member and two ends for engaging into two orifices of the nut member, and the nut member includes a straight fence formed between the orifice and the screw hole of the nut member for guiding the ball bearing members to move through a ball return pathway of the ball return pipe and the endless ball guiding passage of the nut member and for preventing the teeth of the nut member from being broken by the ball bearing members.

A second sealing film F2 is thermally bonded onto a leading end portion R1 of an ink lead-out member 32b of an ink pack and an annular projecting portion R2 provided on an ink casing 31. Thereby, a gap D produced between the ink lead-out member 32b and the ink casing 31 can be closed from outside the ink casing 31. Accordingly, the airtightness of a space S in the ink casing 31 is kept, thus making it possible to raise the pressure in the space S and generate such a force as to crush the ink pack.

Accuracy in determination of the attaching direction of an elongated cartridge is improved. A cartridge 4A according to this embodiment to be attached to a printer includes an ink supply port 414 that supplies ink to the printer, a misinsertion prevention upper face projection portion 140 that engages with misinsertion prevention portions 671 of a misinsertion prevention plate 160 in a cartridge attachment portion 6, and restriction front upper face projection portions 430 that abut against a first guide rail 650 and a first guide rail 651 and restrict a tilt of the cartridge in an intersecting direction that intersects the attaching direction at the time of attachment. These restriction front upper face projection portions 430 are arranged between a leading end side in the attaching direction CS and the misinsertion prevention upper face projection portion 140.

The invention relates to the field of veterinary biological products and particularly relates to a preparation method of a mink canine distemper virus live vaccine. The method comprises the following steps: inoculating a bioreactor with sensitive cells for vaccine preparation, and culturing by using a micro-carrier; after the sensitive cells are cultured by over 50% and grow into a dense single layer, inoculating the bioreactor with canine distemper virus for enrichment culture; harvesting the virus culture liquid and micro-carrier; performing freeze-thawing and removing the micro-carrier and cell debris to obtain virus liquid; and blending the virus liquid to obtain the vaccine.

A heat dissipating device used for a PCB having a heat generating component includes a vapor chamber, a fin set, and a fixture. The vapor chamber is attached to the heat generating component. The fin set is connected above to the vapor chamber. The fixture is fixed to the PCB. The vapor chamber and the fin set are clamped between the fixture and the PCB. The fixture has a press plate which is pressed against a top of the fin set. Therefore, the press plate presses the vapor chamber without direct contact. That is, the applied pressure is concentrated on the fin set and then distributed evenly to the vapor chamber, which prevents deformation of the vapor chamber due to uneven pressure and further achieves the effect of the vapor chamber being attached smoothly to the heat generating component.
