Title: Cutting-off grinding method using current-carriable grinding wheel
Inventor: KUROMATSU AKIO
IPC: B24B53/00
Filed: 1984-06-14
Abstract: PURPOSE:To make high grinding capacity and continuance attainable as well as to aim at the prolongation of service life in a grinding wheel, by grinding a work continuously while dressing a peripheral surface of the conductive grinding wheel by means of mechanical, electrical and electrochemical actions. CONSTITUTION:While grinding work M, a dressing electrode 6 is made contact with a peripheral surface of the rotating wheel 1, and when a dressing power voltage is impressed on the wheel as feeding a contact part with the specified coolant, discharge, electrolytic and mechanical polishing actions are all produced between them, therefore chip dust of the work M sticking to on the peripheral surface of the wheel 1 is removed clean and thereby dressing takes place, so that the work M is ground under optimum conditions. Thus dressing takes place during operation, and a working surface of the wheel 1 is always kept in a state of no loading whereby highly efficient grinding is made performable and, what is more, a finished surface of the work M is very little in stain and defect and a characteristic inherent in the work M is in no case largely varied. In addition, becuase of a light polishing action, wear in the wheel is so little, that its service life is well prolongable.

Title: Producing separator for keeping two plate apart and indicator therefor
Inventor: HOFMANN HORST
IPC: G02F1/133
Filed: 1979-09-21
Abstract: Fiber-shaped metal-containing spacing elements having a well-defined diameter of less than 100  mu m for spacing two plates in an indicia display device, such as a liquid crystal cell, are produced by providing a wire composed of a metal selected from the fourth to sixth adjacent groups of the Periodic Chart of the Atoms, converting the peripheral surface layer of such wire into a brittle metallic compound and breaking-up the so-treated wire into desired size individual spacing elements. By utilizing metal wires, an exact diameter dimension can be attained and by chemical conversion of the wire surface, the produced metal wire loses its ductility and can be easily broken-up into desired size elements. Spacing elements of the invention are useful in all types of indicia display devices particularly in multiplex liquid crystal display devices.

IPC: B41J2/44
Filed: 1993-04-26
Abstract: PURPOSE:To reduce noise caused by an air flow flowing out from the cover of a rotary polygon mirror. CONSTITUTION:The rotary polygon mirror 1 is covered with the almost cylindrical cover 2 and the cover 2 is provided with a window 3 where a laser beam is passed through. On the side edge 3b of the window 3 on a downstream side in the rotating direction of the mirror 1, a guide piece 4 provided with a first part 4a projecting along the tangentical plane A of the cylindrical part 2a of the cover 2 in a reverse direction to the rotating direction and a second part 4C inclined to the rotating direction from the projecting end 4b of the first part 4a is provided. Since the projecting end 4b is positioned more outside in the diameter direction than the inner surface of the cover 2, the air flow flowing out to the outside by getting over the end 4b is decelerated according as it is distant from the surface of the mirror 1. In addition since it smoothly flows along the second part 4c of the piece 4, the large noise is not caused.

Title: Combustor
Inventor: KUSAKA TAKAAKI
IPC: F23N5/10
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent heat exchanging efficiency of a heat exchanging means from being lowered with bubbles generated in a heat carrier through evaporation thereof by collecting them through a bubble collecting means. SOLUTION: Since a forcible heat carrier circulation means 11 is driven through use of thermal electromotive force of a thermoelectric converting means 14, a battery is not required and the size of a combustor can be reduced along with the running cost. Furthermore, since a bubble collecting means 17 collects bubbles generated in a heat carrier, the bubbles are prevented from entering into the forcible heat carrier circulation means 11, and heat carrier circulation power can be ensured. The bubble collecting means 17 comprises a heat receiving part, constituting one surface of an enclosed case, and the heat receiving part receives heat of combustion exhaust gas and exchanges heat with heat carrier in the enclosed case.  Since heat of combustion exhaust gas is utilized effectively, an extra heat exchanging means is not required, and high heat exchanging efficiency is realized while saving space.
