Title: Elevator type multistory parking apparatus
Inventor: UDA WATARU
IPC: E04H6/18
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To increase motor vehicle storage capacity and improve space efficiency by increasing the number of parking sections with a higher range of a diagonal line limitation, and extending upward an elevator shaft and an elevator by an increase in the number of parking sections. SOLUTION: Parking sections 6, 7 are formed on both sides of an elevator shaft 2, and a traverse carriage 8 is installed in a manner that allows it to traverse. In such case, the right parking section 6 is limited by a diagonal line limitation 9 up to the right uppermost parking section 61. The left uppermost parking section 71 and the elevator shaft 2 can be set up to a level higher than the right uppermost parking section 61. The number of parking sections on the left parking section 7 side is set at a higher level than the right parking section 6 side beyond the elevator shaft 2 that is limited by the diagonal line limitation 9 at a higher level. Therefore, it is possible to increase the motor vehicle storing capacity, improve space efficiency, and meet the request of the client for storage capacity.

Title: Apparatus for manufacturing, conveying and transferring frame member
Inventor: USHIBA MASATO
IPC: B65G47/52
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To deal with the case that frame members having different lengths are included by installing a movable positioning unit along a side plate, disposing an irradiator for emitting a laser beam at each interval for mounting a support material at the positioning unit, and mounting the plate at the material with the beam as a reference. SOLUTION: Support materials 8 are sandwiched between a set plate 7 and a side plate 6a via a moving unit. Thus, the plate 6a and plate 7 (side plate 6b) of a frame member 1 are positioned. And, when a positioning unit 2 is moved with its position as a reference, positions for mounting the materials 8 are irradiated directly with a beam 4a by an irradiator 4, and hence the materials 8 are mounted at the plate 7 and plate 6a to meet the beam 4a. The materials 8 are fixed from outside of the plate 6a by hitting nails 10 to fix the materials 8 to the plate 6a. Since the plate 6b of opposite side can be easily fixed via the nails 10 since the materials 8 are mounted, thereby forming the member 1 of a rectangular shape.

Title: Brake for bicycle
Inventor: NAGANO MASASHI
IPC: F16D51/00
Filed: 1981-05-01
Abstract: PURPOSE:To obtain an extremely great braking force even through the input power is small, by a self-braking force in combination with a pressing force of a rotating body and a cam surface. CONSTITUTION:An operation arm 5 can be swung about a pivot shaft 10 by the pulling force of a wire W to cause a shoe 2 and a holder 3 to swing about a first rotating body 7 so that the shoe 2 becomes in contact with the inner circumferential surface of a drum 1. At this time, the rotation is accompanied by movement of the shoe 2 and the holder 3 in a direction of X indicated at an arrow. Due to this movement, the second rotating body 8 is abutted on a second limit member 42 of a fixed member 4, and thereby the body 8 is prevented from the rotating. As a result, the forward side of the rotationally moved holder 3 is pressed by the second rotating body 8 and a second cam surface 8, and therefore the shoe 2 is forced to in contact with the inner circumferential surface of the drum 1.

Filed: 1995-03-27
Abstract: PURPOSE: To achieve miniaturization and to facilitate adjustment of the timing of bringing contacts into contact by providing a pair of links each of which is pivoted to a first pin at one end and to a second distant pin at the other and which cross each other in a cruciform. CONSTITUTION: A pair of links 46, 47 are each pivoted to first pins 32, 33 at one end and to second distant pins 42, 43 at the other and cross in a cruciform. In a breaking state, when an insulating rod 37 is pushed upward by driving an operating part, a connector 41 is pushed upward via a contact pressure spring 45, and the positions of the pins 42, 43 move upward. Then the links 46, 47 pivoted to the pins 42, 43 are each pushed upward at one end while the other ends move in a direction in which they move apart. Next, rollers 34, 35 are guided into slide motion by a guide groove 36, and operating rods 29, 30 move outward, forcing movable contacts 27, 28 into contact with corresponding fixed contacts 25, 26. Therefore, the links 46, 47 can be made longer without an increase in the area occupied, resulting in device miniaturization.

Title: Image reader
Inventor: KUSUNOKI TADAKAZU
IPC: G06T1/00
Filed: 1990-03-20
Abstract: PURPOSE:To secure read accuracy for low-lightness colors and to obtain a read image with a superior contrast by irradiating a sensor with light by a constant fine quantity and thus correcting the nonlinearity in a low-light-quantity range. CONSTITUTION:A light source 8 which emits a fine quantity of stable light is provided for offset correction to irradiate the photodetection surface of the sensor 4 and an output signal of a photodetecting element which is generated with correcting light is subtracted from an output signal of the photodetecting element which is generated with reflected light and correcting light at the time of a read of an original 1. Consequently, only a linear area can be utilized effectively without using the nonlinear part in the low-brightness area of the sensor 4. Consequently, the read accuracy with low brightness is secured and the read with the good contrast is enabled.

Title: Device for detecting blur on window glass
Inventor: KUME KAZUAKI
IPC: G01N21/47
Filed: 1980-05-21
Abstract: PURPOSE:To make it possible to detect the blur on the window glass without fail regardless of the effect of the temperature, by detecting the difference between reflectivity of reflecting plate which is thermally joined with the glass and the reflectivity of the reflecting plate which is thermally insulated from the glass. CONSTITUTION:The reflecting plate 7a is attached to the glass 1 with a plate 8 having a good heat conductivity. Therefore when moisture is also attached to the reflecting plate 7a, the blur is yielded. At this time, the rate at which the light from a light emitting element 4 is dispersed becomes high, and the output of a light receiving element 3 is decreased. Since the other reflecting plate 7b is thermally insulated from the glass 1 by a plate 9 having good heat insulating property, the blur is not yielded. Therefore, the output of the light receiving element 5 maintains a constant value. When the output of the light receiving element 3 is decreased by a specified rate, the output of a comparator 10 is inserted, and the yielding of the blur can be detected. Thus the blur on the glass can be detected without fail, and  the attachment to the glass an be readily accomplished.

Title: Dynamic pressure fluid bearing
Inventor: OUCHI HIRONOBU
IPC: F16C17/10
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To provide the dynamic pressure fluid bearing capable of more suppressing a rotary shake than heretofore. SOLUTION: A rotary thrust plate 115 is formed to be gradually thicker from the inner circumferential side to the outer circumferential side, and an upper surface 116a of a bearing part 116 to be opposite to a lower surface 115a of this rotary thrust plate 115 is formed to be flat surface. Consequently, a gap between the lower surface 115a of the rotary thrust plate 115 and the upper surface 116a of the bearing part 116 is gradually narrower toward the outer circumferential side. When the rotary thrust plate 115 is rotated, a lubricant fluid on the discoid surface is moved to the outer circumferential side, whereas since the gap with the bearing part 116 is narrower toward the outer circumferential side, the lubricant fluid is most compressed on the outermost circumferential side so that a dynamic pressure is generated.  By this dynamic pressure of the lubricant fluid, a thrust load can be supported.
