摘要:
An ion flow recording apparatus performs recording making density modulation every pixel. When developing on a fine grain toner is to be performed using a liquid developer for an electrostatic latent image, a developing unit (developing roller) is disposed to face a direction of gravity. Namely, a control valve is provided on a pipe for application of a developer to the developing roller or on a joint portion between the pipe and a developer tank, developing units of different two colors are joined to their developer tank portions, and a rotary shaft is provided on the joint portion to be positioned at a point of symmetry to provide alternate use of the two developing units upon turning them. Therefore, developing for a plurality of colors can be simply performed, and such turning of the developing units enables prevention of the toner from deposition in the liquid developer during developing, thereby making it possible to perform a clear recording.

In a method of manufacturing a semiconductor integrated circuit device composed of a bipolar transistor and metal-oxide-semiconductor (MOS) transistors, first and second gate electrode structures are formed to have polysilicon layers having no impurity implanted and to be provided on a gate oxide film. First impurity ions are implanted in self-alignment with said first gate electrode structure to form an N-channel MOS transistor. Second impurity ions are implanted in self-alignment with said second gate electrode structure to form a P-channel MOS transistor after a bipolar transistor is formed.

An otorhinolaryngological treatment device includes: a flexible elongated body to be introduced into an accessory nasal cavity through a nasal cavity; an expansion body which is provided on the elongated body and has an effective expansive section capable of radial expansive deformation within a natural ostium between the nasal cavity and the accessory nasal cavity to thereby force open a stenosed part of the natural ostium; and imaging unit for obtaining an image on the front side of a distal end of the elongated body, which is provided integrally with the elongated body on the distal side of the elongated body relative to the expansion body. The treatment device enables easy positioning (aligning) of the expansion body inside the nasal cavity, without need for radioscopy.

Disclosed is a method for dilating between spinous processes wherein a filamentous body provided with an expansion body is percutaneously inserted to locate the expansion body between the spinous processes, a filling material is injected into the expansion body to dilate between the spinous processes, and the expansion body is cut off from the filamentous body to be located between the spinous processes. This method exerts very little burden on the patient.

In an optical pickup, it is configured such that a first and a second thrust bearings of a motor rotation shaft, a lens holder to be moved in a thrust direction by the motor rotation shaft, and a preload unit which exerts preload of the thrust direction on the lens holder are included, and the second thrust bearing can adjust a position in the thrust direction. In addition, the first and second thrust bearings and the motor rotation shaft are made of conductor, and the optical pickup is manufactured by including the processes of: moving the second thrust bearing in a direction approaching to the motor rotation shaft till electrical continuity between the first thrust bearing and the second thrust bearing is obtained using an electrical continuity checker; subsequently moving the second thrust bearing in a direction departing from the motor rotation shaft; and subsequently fixing the second thrust bearing to the base.
