Respective orifices are so disposed as to bring circles of same diameter almost into contact with one another with respective orifices as their centers.  The internal energy of fuel flows is reduced by the arrangement, and a fuel collides with respective orifices to be formed into atomized particles. Also overlapping of atomized particles on a site to be atomized can be controlled.

Abstract: PROBLEM TO BE SOLVED: To cover the shortage of the toner charging amount resulting from the decrease of surface magnetic flux density when the magnetic pole pitch of a magnetic field generation layer is intended to be finer in order to reduce the linear velocity ratio of a developing roller to a photosensitive member. SOLUTION: A toner regulation means 54 is brought into elastic contact with the surface of a flexible developing roller 49 which is equipped with an elastic body layer 51 and a magnetic field generation layer 52 having a fine magnetic pole pitch. A toner layer thickness is regulated as injecting charge to a toner by bias application of a same polarity with a toner charging polarity by the toner regulation means 54. Thereby, even in conditions in which the magnetic pole pitch of the magnetic field generation layer 52 is fine so that surface magnetic flux density is low, a shortage portion is compensated by forcible charge injection through the toner regulation means 54.

An output signal (c) of the non-linear amplifier 2 has the components of a low frequency by the pattern of the reproducing signal (a), a signal (d) of the components can be removed by the integrator 3, and, by comparing-operating the output signal (d) and an output signal (b) of the differentiator 1 by means of a comparing computing element 4, the digital signal can be obtained. Thus, even at the time of using the head and medium where the resolution is low, the correct bit detection can be executed.

Title: Manufacture of lithium ion secondary battery electrode
Inventor: KAWAMOTO KOJI
IPC: H01M4/139
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To prevent the electrolyte density in an active material from being decreased to reduce a capacity, when the electrode temperature rises at the time of battery operation by connecting an active material and a current collector with a binder swollen due to a temperature rise, and impregnating it with a heated electrolyte. SOLUTION: An active material and a current collector are connected by a binder, such as PVDF, swollen by a temperature rise to obtain a lithium ion secondary battery electrode with the filling factor of 55-70%. The connected electrode is impregnated with an electrolyte heated to the temperature reached, when a battery is operated, e.g. about 60-120 deg.C. The binder is kept at the stable swollen state after the temperature is returned to the room temperature, the impregnation quantity of the electrolyte is increased, and the filling factor is set at 50-65%.  As a result, the electrode which holds much electrolyte causes no lack of the electrolyte filling between active material grains, when the temperature rises and the binder is swollen during a battery operation and prevents reduction in the battery capacity caused by ion conductivity deterioration due to the electrolyte density reduction.
