Title: Reflection type display element
Inventor: KOBAYASHI HIDEKAZU
IPC: G02F1/1333
Filed: 1993-03-04
Abstract: PURPOSE:To provide the bright reflection type display element having a wide visual angle and to realize the bright reflection type display having a large capacity and wide visual angle by using substrates having a high refractive index as substrates for holding a liquid crystal/high-polymer layer. CONSTITUTION:This display element is so formed that the refractive index near the surface of the front side substrate 1 in contact with the liquid crystal 3/high-polymer 4 layer is >=1, more preferably >=1.5. Since the refractive index of the substrate 1 is much higher than the refractive index of air and, if the light is made incident in a diagonal direction, the light is made incident at a nearly perpendicular angle on the liquid crystal 3/high-polymer 4 layer. The light exclusive of the light penetrating from the front surface, is consequently made incident eventually at the nearly perpendicular angle on the surface of the display element and, therefore, the scattering efficiency is improved. The light emitted to be scattered in the direction to the front surface is emitted in a diagonal direction at the boundary between the substrate 1 and the air and, therefore, the visual angle is eventually widened. The effect is higher if the display element is applied particularly to a display element having scattering with large dependency on the visual angles, among the display elements of the light scattering type.

Title: Board material for construction
Inventor: SAKAKIBARA TAKASHI
IPC: E04F13/14
Filed: 1993-02-10
Abstract: PURPOSE:To provide a board material being stuck on the surface of a concrete building and being also proper as the backing of a tile wall. CONSTITUTION:Polymer cement cured-article layers 2, 3 containing hydraulic cement, sand and an organic high molecular substance as components are mounted on both surfaces of an artificial slate board 1. Adhesive properties by sand mortar are improved by the polymer cement cured-article layers. The arranged decorative boards of factory products, in which quality is improved, are used, thus shortening the term of work, then also reducing trouble such as a peeling accident after the completion of construction. Since adhesive properties with mortar are enhanced on both surfaces, a board material for construction is proper to the intermediation of a concrete placed wall and tiles. Accordingly, the troweling of a wail having inferior workability and narrow width is unnecessitated.

Moreover, the vibrator 10 is not driven except the video recording and the vibration is not delivered to the hand of the photographer, then, the mode not being in the video recording is confirmed. Thus, the operating mode is easily confirmed in comparison with the case of a conventional device such as visual confirmation of character display or the like.

Title: Formation of silicon oxide film
Inventor: SASAKI MOTOI
IPC: H01L21/316
Filed: 1993-02-09
Abstract: PURPOSE:To provide the ceramic type silicon oxide film which is a thick film, is flat, is free from cracks and pinholes and is insoluble in an org. solvent by heating a base material on which a film mainly consisting of the silicon base resin expressed by specific general formula is formed. CONSTITUTION:The film mainly consisting of the silicon base resin expressed by the general formula: (HR2SiO1/2)x(SiO4/2)1.0 is formed on the surface of the base material. In the formula, R is H, alkyl, aryl; X is 0.1<=X<=2.0. This base material is then heated to convert the film to the ceramic type silicon oxide film. The desired film which is flattened in >=1mu level difference and does not contain silanol groups and alkoxy groups to be the cause for moisture absorption and carbon poison in the formed silicon oxide is formed at the temp. much lower than the m.p. of Al by this method. A tendency to high polymn. is admitted during preservation in a gelatinized or molten state at the time of synthesis if X in the formula is below the lower limit. On the other hand, the sufficient film hardness is not obtainable if X is above the upper limit.

Title: Four-wheel steering gear for vehicles
Inventor: KANAZAWA HIROTAKA
IPC: B62D7/15
Filed: 1984-03-08
Abstract: PURPOSE:To secure a steering ratio corresponding to a running state, by controlling both operations of a first connecting member connecting front side link members themselves of symmetrical rear wheels and a second connecting member connecting rear side link members themselves, while making the steering ratio of front wheels to rear wheels variable. CONSTITUTION:In time of left turning operation of a wheel 3, symmetrical front wheels 2L and 2R are steered to the left. Simultaneously, pressure in a right chamber 7d of a front cylinder 7 goes up and transmitted to a right chamber 14d of a front side rear cylinder 14. Therefore, a piston 14b moves to the left and thereby rear wheels 9L and 9R are steered to the left. Thus, a steering ratio of front wheels to rear wheels comes to be constant. When a steering angle of these front wheels becomes more than the specified value, a flow dividing valve 22 is selected by pressure in the right chamber 7d whereby the pressure is led into a right chamber 15d of a rear wheel rear cylinder 15, and these rear wheels are therefore steered to the right. Afterward, the flow dividing valve 22 is restored, and these rear wheels are steered to the left again. Since the valve 22 repeats these operations, these rear wheels are steered at a steering ratio different from the preceding one. Making spring load of both valves 21 and 22 is made variable so that such a steering ratio as being commensurate to a driving state is securable.

Title: Constant voltage generating circuit
Inventor: TORIMARU YASUO
IPC: H01L27/04
Filed: 1988-02-26
Abstract: PURPOSE:To set the output voltage at a desired level with control applied to the voltage after its generation by connecting one of two ends of each of plural switch elements with which the switching actions are programmable to each connection point of a MOS transistor TR together with the other end of the switch element short-circuited with each other to obtain the constant voltage output at said short circuit part. CONSTITUTION:When a current is supplied from a power supply 1 via a high resistance 2, this current energizes a series circuit containing eight MOS TR7-14 via the programmable elements 15 and 19. Then the voltage of (8XVt) is obtained at an output terminal 20 when the threshold voltage of each MOS TR is set at Vt. If said obtained voltage is lower than a prescribed level, the fuse of the element 19 is cut by a laser trimming device for acquisition of the (9XVt) output. Furthermore the (10XVt) output is obtained with cut of the fuse of the element 18. As a result, the output voltage can be controlled within a range of (8XVt)-(12XVt).
