Title: Macro system for zoom lens camera
Inventor: ITO TAKAYUKI
IPC: G03B3/10
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain a macro system by which zooming can be performed in the case of a set short photographing distance by actuating either a total moving means or a relative moving means and maintaining a focusing state on the short photographing distance when a zoom operation means is operated. SOLUTION: This system is a system to perform zooming while maintaining the focusing state when the zoom operation means is operated in a state where a camera is moved and fixed at a position to focus on a macro photographing distance set by a macro area subject distance setting means. Namely, zooming is performed while keeping the focusing state as shown by lines M1 to M3 at specified macro photographing distance m1 to m3 being an AF unfeasible distance, which is shorter than an AF feasible subject distance area (AF area). Then, the macro zooming is performed by drying at least either the total moving means for driving a total moving motor or the rear group relative moving means for driving a rear group moving motor.

Title: Slag tap type cyclone combustion furnace
Inventor: KAWAMOTO MASAO
IPC: F23G7/00
Filed: 1983-05-09
Abstract: PURPOSE:To contrive to improve the catching efficiency of ash content by a method wherein a ratio l/D of the length (l) of a furnace main body to the inside diameter D of the furnace main body is specified. CONSTITUTION:If the inside surface area of a furnace is made larger by employing a larger ratio l/D of the length (l) of a furnace main body 1 to the inside diameter D under the condition that the volume of interior of the furnace is kept constant, the temperature of flames becomes lower and consequently the slag becomes difficult to melt, causing to lower the catching efficiency of ash content. The upper limit of the ratio l/D is about 3.5. On the contrary, if the ratio l/D becomes smaller, the inside surface area of the furnace becomes smaller and consequently the small heat dissipation is resulted and the catching efficiency can be prevented from lowering. However, because ashes are discharged outside the furnace before being scattered onto the furnace wall by being applied enough centrifugal force due to the swirling stream of flames, the lowering of the catching efficicney is resulted. The lower limit of the ratio l/D is about 1.5. Accordingly, the ash content can highly efficieny be caught by setting the ratio l/D in the range of 1.5-3.5.

Consequently, when the resistance value is varied to a high direction, the base voltage of the transistor Q4 are varied to a high direction. The variation of the operation current of the circuit 1 can be reduced with respect to the variation of the resistance values of the resistors R6 to R10.

Abstract: PURPOSE:To restrain the self-discharge, and improve the preserving characteristic by arranging a sulfonated polypropylene resin nonwoven fabric sheet in a position to get wet in alkaline electrolyte. CONSTITUTION:A sulfonated polypropylene resin nonwoven fabric sheet 2 is arranged so as to cover a winding base end part 1a with one electrode sheet (a positive electrode sheet or a negative electrode sheet) 1.

IPC: B41J2/425
Filed: 1981-05-26
Abstract: PURPOSE:To eliminate the deficiency of recording density due to breakage of recording layer by a method wherein the recording impedance of an energized recording sheet is adjusted based on grain size distribution of conductive material powder formed of metal oxide. CONSTITUTION:When an energized recording sheet is manufactured by forming a recording layer on a support member, the layer containing conductive material powder formed of metal oxide, color forming materials and bonding materials, grain size distribution of the conductive material powder formed of metal oxide is adjusted thereby to control recording impedance desirously and hence to reduce the degree of a stink which is generated due to breakage of the recording layer or at the time of recording. As conductive powder, powder of zinc oxide is preferable which has grain size distribution in a range of 0.3-2.0mum and the mean grain diameter of about 1.0mum. On this occasion, as grain size distribution becomes smaller, recording impedance of the energized recording sheet is reduced, while the impedance is increased as grain size distribution becomes larger.
