Abstract: PURPOSE: To form a unique compound three-dimensional pattern consisting of the pattern of a mold and that of an expansion sheet by placing an expansion-deformable sheet in a mold having a three-dimensional pattern on the inner surface and charging a curable ornamental material composition into the mold.  
     CONSTITUTION: An expansion-deformable sheet B comprises a film 1 provided thereon with sections 2 expansion-deformable by contact with the liquid component of a curable dress material composition 4 and with sections 3 non-deformable by the contact. The sheet B is placed along the internal surface of a mold A having an internal-surface three-dimensional pattern a. Then, the composition 4 brings the sheet B into close contact with the internal surface of the mold A, and a pattern corresponding to the pattern of the mold is formed at the bottom portion of the ornamental material layer 4. After a while, the sections 2 of the sheet B undergoe expansion deformation to form a minute three-dimensional pattern corresponding to the bottom portion of the layer 4. On curing of the layer 4, the assembly of the layer 4 and the sheet B is taken out of the mold A, to yield a formed dress materia product.

Title: Headlight for car
Inventor: NINO NAOAKI
IPC: F21V5/00
Filed: 1988-06-06
Abstract: PURPOSE:To prevent solar beams reflected by the inner surface from concentrating at one point and make the construction light in weight by using a projection lens which is a Flesnel lens having a cut part on the front. CONSTITUTION:A lens 8 used as a projection lens has an inner surface 8a formed in plumb plane, and Flesnel cut is applied to its front 8b. The focal point F is situated approx. in the middle of the light shutting edge 7 of a light shutting member 6 in its left-right direction. Thereby solar beams 9, 9,... incident on the front 8b of the lens 8 from its front above are dispersed in different directions by this Flesnel lens, which prevents the solar beams outgoing from the front upon being reflected at the inner surface of the lens from concentrating at a certain point a head and below the lighting fixture. At the same time, the thickness in the middle of the lens 8 can be reduced to accomplish making the lens 8 light in the weight.

Title: Fluid bearing device
Inventor: YAMAMOTO SEKINORI
IPC: F16C17/10
Filed: 1985-06-24
Abstract: PURPOSE:To enable to reduce sharply the number of rotations for starting floatation, by closing the breather of the thrust portion of a bearing in case of starting, and opening the breather during rotations. CONSTITUTION:Because on opening/closing member 4 is an elastic body, its central vicinity makes contact with a thrust bearing member 12. Thus, a breather 4a is closed up. When rotors 12, 3, 4 rotate, internal pressure in gaps 5a, 5b becomes high so that the rotors 12, 3, 4 float. As the breather 4a remains to be closed up immediately after the rotors 12, 3, 4 started to rotate, the pres sure reduction of fluid streamed into from an arrow A position is prevented. Therefore, flotation time of the rotors 12, 3, 4 becomes earlier and the flotation starts at a low rotational speed, so that the number of rotations can be sharply reduced.

Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a building structure provide with a security function by which a person who destroys the wall of the building and tries to intrude into the building is excluded. SOLUTION: In the building (floor) 100 with the building structure, a circular inner wall 2 with a strength being larger than that of an outer wall 1 is arranged at a prescribed space interval at the inner side of the outer wall 1, the part between the outer wall 1 and the inner wall 2 is made to be a circular crime preventing area 3 and crime preventing sensors 7 are disposed at the four corners of the area 3. Furthermore, the inner side of the inner wall 2 is regarded as a security area 5 where confidentiality is required, and a see- through partitioning wall 4 for partitioning the area is arranged in the security area 5. Besides, the partitioning wall 4 is provided with a vibration sensor 6 for detecting the vibration in the case the partitioning wall is destroyed.  By this building structure, the destruction at the wall becomes increasingly difficult since the strength of the inner wall 2 is larger than that of the outer wall 1 even when someone destroys the outer wall 1 and tries to intrude into the building. Each area is seen through by the see-through partitioning wall 4 so that an illegal action by an insider is also restricted.

Inventor: SHIBUSAKA AKIO
IPC: G06F3/0354
Filed: 1992-04-28
Abstract: PURPOSE:To facilitate handling and maintenance and to improve operability by rotating a ball which is freely rotatably supported by means of a casing in a desired direction and detecting the rotary direction and a rotational amount. CONSTITUTION:A means radiating detection light consisting of coherent light toward the surface of the ball 6 and a means receiving the reflected light of detection light from the ball 6 are given. The surface of the ball 6 makes a diffusing surface, and the light-receiving means receives the reflected light of detection light from the ball 6. The rotary direction and the rotational amount of the ball 6 are detected from a speckle pattern. Thus, a random pattern on the surface of the ball 6 or the speckle pattern on the diffusing surface can optically be detected and therefore the position of a cursor on a display can always be shifted to the desired position of an operator. Then, a fault due to mechanical contact and errorneous detection can be avoided. Thus, reliability and operability against dirt or the like can be improved.

IPC: F02P5/155
Filed: 1987-06-02
Abstract: PURPOSE:To prevent the occurrence of out-cylinder burning during restarting right after the stop of an engine, by a useless ignition preventing circuit which is actuated by means of a signal from a sensor to detect the useless ignition timing of a magnet ignition type. CONSTITUTION:A sensor 25 is positioned facing a magnet 27 buried in one spot on the outer periphery of a disc 26 secured on a cam shaft 14, and a timing at which a magnet 27 is detected by the sensor 25 coincides with a useless ignition timing. A useless ignition preventing circuit 24 situated at a primary circuit 23 of an ignition device 22 receives a signal, by which a useless ignition timing is reported, from the sensor 25 to render the motion of a breaker 28 ineffective. Namely, the circuit 24 is connected in parallel to the breaker 28, and as a result of the circuit 24 bypassing the primary circuit 23 even when the breaker 28 cuts off the primary circuit 23, the motion of the breaker 28 is rendered ineffective, and no ignition current is generated at a secondary circuit 29. This constitution eliminates the possibility for out-cylinder burning to occur in any engine stop position and restarting position.

Abstract: PURPOSE:To obtain an integrated circuit which is not affected by the direction of the signal change by inserting the plural units of the phase inverting circuit to the signals which are supplied to the 2nd block of the same type of the circuit system as the 1st block and then obtaining the delay time which is identical interms of both the rise and the fall. CONSTITUTION:2n units of phase inverting circuit 10 are inserted to signals S1 supplied to block 2 of the same type of the circuit system as block 1. Then 2n is made identical to the number of the circuits from the signal S1 input to signal S2 output of block 1, and the input signal change of signals S1 and S2 are caused at the same time by using the same types of the circuit system as block 1 for circuit 10. With use of circuit 10, the same delay time can be obtained for both the rise and the fall. Thus a high-accuracy integrated circuit can be obtained with no effect of the direction of the signal change.
