IPC: G03G15/16
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To hardly cause nonuniformity and a difference in speed and to stably form an image by rotationally driving a photoreceptor only with the electrostatic force of a transfer belt to be in close contact with the photoreceptor. SOLUTION: In an image forming device 10, a bias is applied to the transfer belt 13 by a transfer bias roller 11 to transfer a toner image on the photoreceptor drum (photoreceptor) 15 to a transfer paper 17. In such a case, the photoreceptor drum 15 is not rotationally driven with a motor, but rotated by the electrostatic attracting force of the belt 13. This endless type transfer belt 13 is arranged under the drum 15 and fed in the direction of T by the transfer bias roller 11, a driving roller and a driven roller 27. In the vicinity of the lower part of the belt 13, a contact/uncontact lever 31 is arranged and a bias terminal 33 is provided on the contact/uncontact lever 31. The bias terminal 33 is connected to a DC power supply part and high-voltage power is applied.

Abstract: PURPOSE:To obtain a fine channel preventing horizontal diffusion by making source and drain layers at a location corresponding to a channel in the presence of an oxide at the same depth as the source and drain layers. CONSTITUTION:A field oxide film 14 and a thin oxide film 15 are formed on an N type Si substrate 10 and with mask of a nitride film 16 applied, a window is etched in the film 15. An oxide 15 about 5,000Angstrom  thick is made by oxidation and set at the same depth as the source and the drain. After the mask 17 is removed, P type source and drain layers 19 and 20 are diffused down to about 5,000Angstrom  in the depth. Here, horizontal diffusion is checked by the oxide 15 never adversely affecting fine division of the pattern in a channel 21. A mask of a nitride film 22 is made covering an oxide film formed and an oxide 18 is etched away. Then after a gate oxide film 24 is formed, a gate electrode 25 is provided thereon. Finally, windows are selectively etched in films 23 and 22 and then, source and drain electrodes 26 and 27 are provided.

Title: Molding material for audio
Inventor: TSUKAGOSHI NOBUHIRO
IPC: C08L25/06
Filed: 1980-04-15
Abstract: PURPOSE: To provide the titled material which can produce a molded article which is lightweight and has high rigidity, high elasticity and high internal loss, by blending a scaly graphite powder with polystyrene.  
     CONSTITUTION: 90W10wt% Polystyrene (A) (which may be used together with 2W50wt% rubber material such as a nitrile-butadiene rubber) is mixed with 10W 90wt% scaly graphite powder (B) having an average particle diameter of not larger than 20μ. The mixture is kneaded at the softening temp. of the resin by using a kneader or a roller to obtain the desired molding material for audio. The above molding material is used to produce a molded article in which the graphite powder is orientated along the surface of the molded article by press molding (or compression molding). But, when said mixture is rolled into a sheet material by using a roller in the above kneading operation, said molded article may be produced by a vacuum molding method or a pressure forming method, because the graphite  powder has already been orientated in parallel with the surface of the sheet.

Title: Ferroelectric memory
Inventor: ISODA MASANORI
IPC: G11C14/00
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To return an electric field applied to a ferroelectric capacitor to zero accurately to initialize characteristics by a pulse that is not prescribed by conditions such as temperature and stress in a ferrodielectric memory. SOLUTION: In the initialization, switches Sot and Sob are opened and switches Sdt and/or Sdb are closed to connect an attenuation vibration circuit DP to an IO wire. Ferrodielectric capacitors CO-Cn are selected by a line selection signal YSn and required word lines WO-Wn to apply an output Dpo of the attenuation vibration circuit. A potential of a plate line PL is shifted to an intermediate potential of the output Dpo by a plate voltage source VR. The voltage amplitude of the output pulse Dpo is gradually attenuated to turn an electric field applied to the capacitor to zero finally. In the normal operation, the switches Sot and Sob are closed and the switches Sdt and Sdb are opened. Thus, improved degrading in characteristic of the ferrodielectric allows reduction in malfunctioning of the ferroelectric memory thereby enhancing the reliability of a system.

Title: Air blow device
Inventor: UMEKAGE YASUHIRO
IPC: F24H3/04
Filed: 1985-03-12
Abstract: PURPOSE:To prevent a standing wave sound from generating within a blasting device and to make uniform the air flow quantities of both blasting passages on both sides of a combustion cylinder by downwardly inclining the top plate of the blasting duct toward the down stream, outwardly expanding a side plate on a side with which a swirl flow caused by a propeller blower comes into collision from the upward to the downward, toward the down stream, and making the distance between the side plate and the combustion cylinder smaller than the distance between other side plate and the combustion cylinder. CONSTITUTION:A noise generated from a combustion portion 2 is radiated from the upper part of a combustion cylinder 3 toward the direction of a top plate 13, and is reflected in the direction of a top plate propeller blower and no standing wave is generated between the other surface of the blast duct and other surface. A sound radiated from the upper part of the combustion cylinder toward the side plate, is reflected in the down stream direction by a side plate B15, and no standing wave resonance is generated between the side plate and the other surface of the blast duct. Although the upstream side of the side plate B15 approaches the direction of the combustion cylinder 13 and the ventilation resistance on the side of the side plate B becomes higher than the ventilation resistance on the side of the side plate A, air at the top plate part can be enfolded in the passage on the side of the side plate B because the rotation of the vane of the propeller blower is changed from the direction of the top plate 13 to the direction of the side plate 15, thus making the air flow quantity in the passage on the side of the side plate B equal to that in the passage on the side of the side plate A.

Title: Dielectric resonator
Inventor: SAITOU TOSHIYUKI
IPC: H01P7/10
Filed: 1979-04-23
Abstract: PURPOSE:To prevent the variation in the resonant frequency from the moisture in air, by clipping the dielectric resonator with metal plates via the dielectric substance of low dielectric constant. CONSTITUTION:The dielectric resonator 1 is clipped with the dielectric substance 5 having low dielectric constant and the dielectric resonator is supported by locating the metal plate 6 at the upper side and the metal case 2 at the lower side. The hole 7 is made from the metal case 2 to the dielectric resonator 1, and the rod 9 made of dielectric substance is inserted in it. Since the dielectric resonator itself is not exposed outer side, it is not subjected to the effect of moisture in air, resulting in stable resonant frequency. Further, the resonant frequency can easily be changed by changing the amount of insertion of the rod 9 of dielectric substance.

Abstract: PURPOSE:To aim at improving an insert shroud in its strength per area, by performing a grinding under on four corners of an integral cover into which the insert shroud is inserted in a direction of turbine rotation.

Thus the insert shroud can be straightened so well without froming a radius-form grinding undercutting part between its blades, so that stress concentration may be avoided and, what is more, improvements in its strength per area is well promotable.

Title: Electrophotographic copying machine for film copying
Inventor: TAKAHASHI HIROSHI
IPC: G03G15/043
Filed: 1985-03-14
Abstract: PURPOSE:To obtain always a clear picture by varying a lamp voltage loading with respect to the loading of a film fog density. CONSTITUTION:When a film 2 is transported on a platen 1, a halogen lamp 3 lights up at a regulated voltage. The film transmitted luminous energy at this time is read by three luminous energy sensors 13-15, and among three readout luminous energy signals, the lace where the lowest voltage is detected is judged to be the fog density of the film. With this fog density as a reference, the reference lamp voltage of the halogen lamp 3 is set. Thus the lamp luminous energy is made variable in accordance with the contrast of the film, and a clear copied image can be obtained by matching the film having any density.
