Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the cost of pulverization to a fragmentary form is not sufficiently reduced in the case ore type raw materials (including molten slag obtainable by heating and melting the incineration ashes of refuse, sewer sludge, etc.) are recycled as building raw materials and calcined product raw materials. SOLUTION: The ore type raw materials (molten slag) 8 melted by heating is supplied into a cooling liquid layer 11 flowing down while swirling along the inside wall surfaces of a cylindrical body 2 for cooling through the molten metal nozzle hole 6 of a raw material vessel 1, by which the ore type raw materials broken down to the fragmentary form are obtd. Further, a gas jet Gj is blown to the molten slag flow 8a flowing down from the raw material vessel 1 to break down the raw materials to a fibrous form and thereafter, the raw materials are injected into the cooling liquid layer 11 and are solidified. As a result, the finely pulverized raw materials are obtd. in a short time. In addition, the recovery is easy and therefore, the raw materials are provided as the power and granular and further, rock wool-like ore type raw materials.

Title: Drill
Inventor: SHIGA SEIKI
IPC: B23B51/00
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To decrease the manufacturing cost of a drill comprising a blade member and a shank, which are different members from each other, fixed to each other. SOLUTION: A blade member 10 comprises a cutting edge 24 formed in a tip section of a cemented carbide alloy flat plate, and a shank 12 comprises a slotted groove 32 axially formed in the tip face 30 of a special steel round bar. The base end section 16 of the blade member 10 is fitted and brazed in the slotted groove 32 of the shank 12. Because the axial dimension of the blade member is twice or more as much as the cross directional dimension, this drill can be used for making deep holes. In addition, because the space on the side of the side face 20 of the blade member 10 is used as a chip discharging groove, the formation of a chip discharging groove in the blade member 10 becomes unnecessary. Therefore, the manufacturing cost of the drill can be decreased.

IPC: F21V5/06
Filed: 1989-08-08
Abstract: PURPOSE: To facilitate the cleaning, exchange and maintenance of a hooked material by holding a hook and a hook receiver in the engaging condition freely to be removed with a bush capable of being slid on a narrow long support bar in the longitudinal direction. CONSTITUTION: At the time of safely hooking a suspending material to be hooked 1 on a support bar 3, a ring of the material to be hooked 1 or a loop- like hook receiver 2 is hooked on a hook 4 of a support bar 3, and a bush 5 is lowered so that a slot 6 thereof is placed on an upper edge of the hook receiver 2. Generation of loose-out of the hook receiver 2 from the hook 4 due to the slip thereof is eliminated. Since the hook receiver 2 and the hook 4 can be partially turned at a using position, the material to be hooked 1 can be vibrated similarly with a hooked material of a luminaire such as an ordinary decorated chandelier and a wall lamp. At the time of removing the material to be hooked 1 from the support bar 3, the bush 5 is slid upward till it is separated from the hook 4 so as to remove the hooked material 1 from the hook 4.  With this structure, cleaning, exchange and maintenance of a device is facilitated.

In this condition, the holding member 30 is rotated around the rotation shaft 16. As a stopper 48 is abutted to a shock absorbing member 28, rotation is stopped. As a result, the first pallet 64, the second pallet 66, and the suction plate 82 become inverted for 180 deg., and they need only be taken out of the insertion hole part 63.

Title: Scattering type display element and its manufacture
Inventor: WAKITA HISAHIDE
IPC: G02F1/1335
Filed: 1993-08-20
Abstract: PURPOSE:To make the element bright and high in contrast by making the refractive index of a substrate border surface which comes into contact with a medium less than or nearly equal to the refractive index when the scattering power of the medium is small. CONSTITUTION:The element is equipped with a substrate 1, the light scatterable medium which is inberted and held with the substrate, and a light absorbing layer 5 which is provided behind the medium and substrate border surface when viewed from an observer side; and the light scattering ability and refractive index of the medium are varied at the same time by voltage application and the refractive index of the substrate border surface which comes into contact with the medium is less than or nearly equal to the refractive index when the scattering ability of the medium is small. Then incident light is transmitted through a liquid crystal layer in a transparent state at the time of the voltage application and at this time, the substrate border surface and liquid crystal are equal in refractive index, so the incident light is transmitted even through the border surface and reaches the light absorbing layer 5 behind it, thereby making a black display. When no electric field is applied, on the other hand, the incident light is scattered by the liquid crystal layer; and part of the light is scattered backward, i.e., reflected and the rest is scattered forward and made incident on the substrate border surface at various angles. The refractive index in the absence of the electric field becomes larger than that of the substrate border surface, so the reflection increases and the light which is reflected by the border surface returns to the liquid crystal layer.

Title: Chip diode
Inventor: HIBINO MITSUTOSHI
IPC: H01L23/34
Filed: 1987-08-19
Abstract: PURPOSE:To reduce a thermal resistance and facilitate higher output performance by a method wherein the circumference of one of jumet wires is expanded while one side or a part of an arc of its region soldered to the other jumet wire is kept in the same plane as the other jumet wire. CONSTITUTION:The circumference of a jumet wire 1a is expanded to left, right and upper directions while only one side of its region soldered to the other jumet wire 1 is kept in the same plane as the other jumet wire 1. As the soldered area between the jumet wire 1a and the conductor on a printed board is expanded, the thermal resistance from a semiconductor element 3 to the printed board can be reduced. Moreover, only one (1a) of the jumet wires is expanded, a parallel capacitance which causes a problem in a radio frequency range is not increased. With this constitution, the higher output performance can be realized.

Abstract: PURPOSE:To simplify a structure and dispense with connection using flexible connectors by folding back the first flexible sheet with a drive chip provided with a formed selection electrode and the second flexible sheet with a common electrode, with a thermal resistance layer allowed to be present in an area between the selection electrode and the common electrode opposed to each other. CONSTITUTION:If a drive signal is connected to the IC chips 10... of the first flexible sheet 5, with the movement of a printing head 1 in relation to a thermal transfer sheet 3, each IC chip is activated to supply an electric current to the selection electrode 9 selectively. This current runs to a common electrode 12 on the second flexible sheet 7. The thermal resistance layer 6 becomes heated due to Joule heat part corresponding to the selection electrodes 9... to which the current is selectively supplied. Consequently, this heat is conducted to the thermal transfer sheet 3 through the common electrode 12 and the second flexible sheet 7 to melt a thermally melting ink layer 15. The molten part of the layer 15 is transferred to recording paper 2 provided below, so that the layer 15 is transferred to the paper 2 in accordance with the heating of the thermal resistance layer 6.
