Title: Inscribed gear pump
Inventor: HOSONO KATSUAKI
IPC: F04C2/10
Filed: 1989-01-20
Abstract: PURPOSE:To enable pump efficiency to be improved preventing an outer rotor from moving its rotary center by allowing pressure fluid from a delivery port to partly flow into a notched part opened to the peripheral surface of the outer rotor so as to urge it by a fluid pressure. CONSTITUTION:When an inscribed gear pump is actuated, fluid of operating oil or the like is sucked from a suction port 4 into space S, and because its volume is decreased following rotation of both rotors 2, 3, the fluid is pressurized and delivered from a delivery port 5. Since two parts of the pressurized fluid are allowed to flow into a notched part 10, by a pressure of the fluid obtaining a high pressure, the outer rotor 2 is urged from the lower, that is, side of space Smax with the maximum volume to a side of space Smin with the minimum volume. Accordingly, since the rotor is prevented from moving during its rotation in a body clearance d1, the rotor can be prevented from moving its rotary center O1, and the pump enables its efficiency to be improved.

Abstract: PURPOSE:To prevent the deterioration in the quality of a copy occuring in the shake, blur, etc. on the copied image owing to the impact when a fixing roller is reset by controlling an image forming means in such a way as to prohibit the starting of the device operation for forming the next image before a means for detecting the completion of transfer detects the completion of the transfer. CONSTITUTION:A detecting switch 10 detects the rear end of set transfer paper 14 and judges a copying prohibition timer phi during the previous copying cycle in the 2nd and succeeding number of copying sheets in a copying mode. Then if a timer Tphi is set, the device is put into the wait state prohibiting the start of the next copying operation until the timer Tphi times out. The transfer paper 14 is completely discharged from a press fixing roll 4 during the period of said wait state and therefore the impact on a driving system is generated during the period when the copying operation is not accomplished so that no influence is given on the quality of the copy at all.

IPC: G11B7/1353
Filed: 1983-01-31
Abstract: PURPOSE:To record the information with a fixed track space in spite of the deflection of an axis by turning a grating so that one of + or - order laser beams is put right above a track that is recorded previously by one round and therefore controlling the track space at a fixed value. CONSTITUTION:The laser beam reflected by a disk 207 is reflected by a polarized beam splitter 204 after passing through an objective lens 206 and a tracking mirror 205. This reflected light passes through an astigmatic optical system 208, and the polarized light of the signal component is separated by a photodetector 209 and received by a photodetector 210. An automatic focus signal, an automatic tracking signal and the information signal of Rf (reception frequency) are obtained by the detector 210. If the difference between outputs of photodetectors 210-2 and 210-3 is controlled to zero, the spot of either one of + or -1 order diffracted beams traces on a track. Thus the recording is carried out with a spot of the O order light having a fixed space.
