Title: Projection type liquid crystal display device
Inventor: OGINO MASANORI
IPC: H04N5/74
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce or exclude deposition of dust onto a surface of a major optical device and to attain thermal dissipation by providing a light guide wall thermal resistance reduction means so as to eliminate the need for a ventilation means between inner and outer spaces. SOLUTION: A Peltier element means is provided to a light guide wall as a light guide wall thermal resistance reduction means. The Peltier element means is made up of a heat absorption side plate 14, a Peltier element 15, a heat dissipation side plate 16 and a heat sink 17. A temperature difference of about 20 deg.C is provided between both the plates by supplying power of about 10W to the Peltier element 15 and a heat flow of about 10W is absorbed from the heat absorption plate 14 (low temperature side) and a heat flow in total 20W is dissipated from the heat dissipation plate (high temperature side). Moreover, a metal material with good heat conductivity is not essential but recommended for a type of material of the light guide wall means 4. The heat absorption plate 14 substitutes the light guide wall means 4. The Peltier element 15 may be arranged at both sides.

Title: Arm control device
Inventor: ABE YASU
IPC: G05B13/02
Filed: 1989-04-17
Abstract: PURPOSE:To perform the positional control of the arm terminal and to shorten the time spent in control without performing a complicated calculation accompanied by a trigonometric function by having a fuzzy inference function and learning function on a control arithmetic device. CONSTITUTION:After starting control, a control arithmetic device 1 calculates the orbit that the arm A terminal should take in order to reach a target point by the input coordinate information. Such a sub-goal that the distance from the present position of the arm A terminal becomes a constant short distance is also set on the orbit thereof. Moreover, the direction to move the arm A terminal is found from the position of the arm A terminal and that of the sub-goal. The control amount of the respective joint is found by the fuzzy inference and the joint is driven by this direction and input joint angle information. The terminal of the arm A can finally be reached to the target point by driving joints a1, a2 by repeatedly performing the sub-goal setting in order.

Title: Organic el element
Inventor: ARAI MICHIO
IPC: H05B33/22
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To improve a contrast ratio and visibility by blacking the base parts of a layer-to-layer insulating layer formed around hole injection electrodes and/or element separating structural bodies. SOLUTION: Since an electron injection electrode 5 is normally formed from a metal, it will reflect external light entering from a board 1 side and thereby causes a contrast ratio and visibility to be degraded. Then, a part of non- luminous parts that does not contribute to light emission is blackened by blacking a layer-to-layer insulating layer 3 and/or the base parts of element separating structural bodies 7, and thereby, the reflected light from the non-luminous parts is restrained, so that the contrast ratio and the visibility are improved. As a means of blacking the base parts of the layer-to-layer insulating layer 3 and the like, they are formed from a black-colored or relatively, close to a black material. For this material, a material such as ferrous oxide, silicon, amorphous carbon or a composition prepared by adding carbon to polyimide resin is preferable.  It is preferable that the quantity of carbon black added to organic resin be 10-50 mol.%.

Abstract: PURPOSE: To work supermirror-finished surface in the stage of combining anodic reaction by electrolysis and the effect of abrasive cutting edge of abrasive grain and controlling the pulse width of electrolytic current and reiterating the same in accordance with max. roughness.  
     CONSTITUTION: In order to control the roughness of a metallic surface to an ultra-specular surface of several 10nm or below, the following process is employed: In order to induce anodic dissolution, at least about 0.5A/cm 2  current density is required in the case of a passivation type electrolyte. If the roughness is assumed that the projection parts of bodies of hyperboloid of revolution having a height corresponding to the max. roughness stand close together, the projecting parts dissolve with DC up to several μRm (Rm is the max. height), and with the pulse width of electrolytic current of 100ms up to 0.1μRm, 10ms up to 0.01μRm, and 1ms up to 0.001μRm. Therefore, the current density is made sufficient for dissolution by increasing the electrolytic gap voltage according to the degree of specular finish; at the same time, the pulsation electrolysis under controlled pulse width is executed.

Title: Image forming device
Inventor: YAGISHITA TAKAHIRO
IPC: B41J5/30
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To form an image with reducsed deterioration while preventing overrunning by controlling whether to omit or not the read compressed data to be the object of extension from a storing means corresponding to compression. SOLUTION: The reading of compressed data stored in frame memory 5 and the expansion processing by an expansion circuit 6 are executed by feedback control. When a detection means 11 detects a data quantity within a FIFO buffer 7 and the detecting result is less than a prescribed value, the reading of data of a part of each sub-block stored in the fame memory 5 is omitted and extension processing by means of the expansion circuit 6 is omitted concerning a part of the sub-block. Thereby data expansion processing is relatively accelerated. By the omission of expansion processing like this, an expancled result by means of the expansion circuit 6 becomes non-reciprocal but it does not matter much because it is known that the deterioration of the image is inconspicuous even when non-reciprocal expansion is executed concerning the image area.
