Title: Power supply, electric device and copying machine
Inventor: IWAO AKIO
IPC: H02M7/12
Filed: 1995-03-28
Abstract: PURPOSE: To prevent the decrease in output voltage even if an input voltage is suddenly changed in high degree by connecting a diode in a reverse direction so that an uncontrollable current does not flow into a field-effect transistor for improving the power factor. CONSTITUTION: A diode D12 is connected between a connecting point (a) of a capacitor C11 and a step-up control field-effect transistor Q12 and a connecting point (b) of a transformer T11 and a power-factor improving field-effect transistor Q11 so that an anode is connected to the side of the connecting point (b). Since the diode D12 is connected between the connecting point (a) and the connecting point (b) with the anode on the side of the connecting point (b), a large current flowing through a choke coil L11 and the capacitor C11 does not flow into the transistor Q11. Therefore, even if an overcurrent protecting circuit is connected to the source side of the transistor Q11, a capacitor C13 does not make a decrease in charging voltage as in the conventional case.

Abstract: PURPOSE:To always perform the stable and excellent image forming with regard to a recording material having a different substrate color. CONSTITUTION:The substrate color density of the recording material is measured by disposing the density sensor in the feeding path of the recording material for detecting the density of the substrate color of the recording material of the image forming subject (S1).

Title: Reverse osmosis membrane type water purifier
Inventor: SASAJIMA KUNIHIKO
IPC: C02F1/44
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To arrange a water tank for purified water above a cock in a reverse osmosis membrane type water purifier. SOLUTION: Purified water obtained in a reverse osmosis membrane unit 10 is stored in a water tank 12 and passed through an activated carbon unit 14 by opening a cock to be taken in. At this time, since the intake port of the water tank 12 is disposed so as to be positioned above the cock, the intake of water from the cock can be smoothly performed without using a pressure means. Since an intake system by gravitational falling is employed, the pressure means in the water tank is dispensed with and the water tank comprising a more lightweight material such as plastic used in place of a metal can be used.

Title: Recording device
Inventor: YAMAOKA TOSHIHIDE
IPC: G03G15/05
Filed: 1985-04-03
Abstract: PURPOSE:To improve the durability of a dielectric by allowing ink particles which are jetted over an electrostatic latent image formation surface to scatter in different direction under the attractive force or repulsive force of an electrostatic field. CONSTITUTION:The negative electrode of a DC power source 4 is connected between an electrode 3 for electrostatic charging and ink particles which are jetted from a nozzle 1 are charged positively and scatter horizontally along the surface of an electrostatic shield member 6. The surface of the dielectric is charged positively except at the image part of an electrostatic latent image and when particles 2 arrive at a slide 5, the image part on the dielectric is not charged positively, so the particles move as they are to stick on recording paper 7 which moves as shown by an arrow (b), thereby forming an image. The particles, however, have their routes bent by their repulsive forces except at the image part and are collected at a collection part 8. Therefore, the surface of the dielectric is not developed, so neither ink nor toner needs to be cleaned and the durability of the dielectric is improved.

Abstract: PURPOSE:To form an SiC coating film having excellent wear resistance by specifying the ratio between the numbers of C ions and Si atoms reaching the surface of an Fe-based alloy substrate per unit time when an SiC coating film is formed on the surface of the substrate by a dynamic mixing method. CONSTITUTION:Carbon ion implantation and silicon vapor deposition are simultaneously carried out on the mirror finished surface of a carbon steel substrate by a dynamic mixing method. In this case, the ratio (C<+>/Si) of the amt. of carbon ions reaching the surface of the substrate to the amt. of evaporated silicon atoms reaching the surface of the substrate per unit vapor deposition time is regulated to 0.26-0.49. An intermediate layer of Fe3C is formed on the surface of the carbon steel substrate by Fe in the substrate and carbon, and a hard SiC coating film is formed on the intermediate layer. The deformation resistance of the SiC coating film to external force is increased by the presence of the intermediate layer and a carbon steel member with an SiC coating film having remarkably improved wear resistance is obtd.

Abstract: PURPOSE:To allow the depressing force of a blade to act upon a photosensitive body effectively and make a device compact by making the center of turning of a blade holding BODY and the center of rotation of a toner carrying means coincident with each other practically. CONSTITUTION:A blade holder 136 holding a blade 134 is fixed to a casing 102 and is provided turnably around the same center as a driving shaft 126 of a coil 128 which is the toner carrying means.

Title: Controlling method for plug closing torque of capper
Inventor: MURANAKA YUKIARI
IPC: H02P29/00
Filed: 1987-03-25
Abstract: PURPOSE:To screw-engage a cap with a vessel always by a predetermined plug closing torque by so controlling the deceleration of a capping head as to become a predetermined value. CONSTITUTION:When a cap 5 is rotated as predetermined and started to be substantially tightened to the vessel 1, the speed of a capping head 4 is reduced. When it becomes this state, a controller 8 so increases a command torque at a predetermined increasing rate. Here, the increasing rate of the command torque is so corrected that the deceleration of the head 4 becomes a predetermined value. When it becomes the speed of the value immediately before the head is stopped, the inertial torque of the head 4 is calculated from the product of the deceleration of the head 4 and the moment of the head 4. The tightening of the cap 5 is finished by the command torque obtained by subtracting the torque from the predetermined plug closing torque.

Filed: 1995-03-29
Abstract: PURPOSE: To surely prevent a paper from winding itself around a platen and discharge the paper normally, by providing a platen rotating with the printing paper wound therearound, a roller rotating in touch with the platen and a roller having vanes in the outer periphery and rotating in touch with the roller. CONSTITUTION: A platen 1 is set to face a thermal head 5, which rotates with a printing paper 4 wound therearound. At the same time, a roller 2 rotating in touch with the platen 1 is provided. Moreover, a roller 3 with vanes which rotates in touch with the roller 2 is provided. When the printing paper 4 printed by the thermal head 5 is transferred in a discharge direction by the rotation of the platen 1 in a B direction, the paper is apt, to wind itself around the platen 1 while in tight, contact, with the surface of the platen 1. At this time, however, tone roller 2 in touch with the platen 1 rotates in a C direction, and the roller 3 with vanes rotates in a D direction, so that the paper 4 is prevented from entwining around the platen 1. The paper is accordingly smoothly discharged in an E direction.
