Title: Spindle motor
Inventor: CHUDA MASANOBU
IPC: F16J15/40
Filed: 1990-10-18
Abstract: PURPOSE:To simplify structure and prevent grease from sputtering to outside a motor by installing a magnetic fluid seal between a pair of bearings mounted at the two ends of a stationary shaft, and omitting provision of magnetic fluid seal in the areas outside of these bearings. CONSTITUTION:A magnetic fluid seal 12 is installed between bearings 5. 6 mounted at the two ends of a stationary shaft 4. This seal 12 is composed of a ring plate magneto 13, pole pieces 14, 15 made from magnetic ring plate pinching the magneto 13 from the sides, and a magnetic fluid 16. Covering members 17, 18 in the form of shallow tray provided with a hole in the center are formed on the side outermore the motor than the two bearings 5, 6, and a pocket 19 is formed as opening to the bore. Accordingly the grease willing to sputter from the bearings 5, 6 can be received by this pocket 19, and therefore, no magnetic fluid seal is provided outside of the bearings 5, 6. The axial air flow inside of the motor is thus hindered by simple structure, and sputter of grease is prevented.

Title: Light source for data imprinting device for camera
Inventor: ITO SHINSUKE
IPC: G03B17/24
Filed: 1988-11-08
Abstract: PURPOSE:To prevent irregular reflection and refraction of light emitted from a light source by applying a paint of light absorbing property to the side and bottom of glass, viewed from the forward optical axis of the light source. CONSTITUTION:To prevent the irregular reflection and refraction of light, the black paint 4 is applied to the front and bottom of the glass 2. As a result, even if the light emitted from a filament 1 hits the glass surface, the paint applied to the side and bottom absorbs the light. Consequently, light is prevented from being reflected irregularly and refracted; therefore light with an angle different from the optical axis direction never reaches film. Out of light beams emitted from a lamp, the one in parallel with the optical axis in front of the forward lamp reaches the film, thereby preventing fogging and a ghost phenomenon.

Title: External field grasping device for blind men and its assistant tool
Inventor: TAKI HIROFUMI
IPC: G01S15/06
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To enable a severe blind person to obtain spatial visual information by combining a device which gives pressure and electric stimulation changing with two-dimensional coordinates to a wearer with an in-air ultrasonic sensor. SOLUTION: To obtain visual information, a pointed needle is placed on corresponding coordinates and pressed more and more strongly as the distance is far, thereby transmitting the information to the wearer instead of displaying the information on a screen. The wearer is able to recognize whether or not there is an obstacle, how near the obstacle is, and its direction. Needles like this are laid at equal intervals in a certain area to give stimulation by the individual needles, and the wearer knows the size and shape of the obstalce and positions relative to others. The pressure can be applied by electromagnets, etc., and the intensity is adjustable with the voltage applied to the individual electromagnets. Further, an ultrasonic wave is always produced at a guidance place for the blind and its spatial position can be recognized through this instrument. Further, electrodes are used as the needles and a large current for short- distance coordinates is supplied to inform the wearer of them.

Abstract: PURPOSE: To improve the sealing characteristic of a slide valve disk and a valve seat and reduce leakage from the slide valve disk by providing pressing means for pressing the valve seat to the slide valve disk side on the surface of the valve seat housed in a hollow guide box opposite to the slide valve disk. CONSTITUTION: An air supply and exhaust device 13 comprises a hollow 16 guide box 17, a valve seat 18 housed in the guide box and a slide valve disk 19 sliding in a reciprocating manner while coming into contact with the valve seat. On the surface of the valve seat 18 opposite to the slide valve disk 19, is formed a pressure bearing surface 25 for receiving refrigerant pressure from the high pressure line 2 of a compressor 1. The valve seat 18 in contact with the slide valve disk 19 receives pressure from the high pressure line 2 on the pressure bearing surface 25 formed on the surface of valve seat 18 opposite to the slide valve disk 19, so that it is pressed to the slide valve disk 19 due to the pressure difference between valve seat and the hollow part 16 of the guide box 17 communicating with the low pressure line 3 of the compressor 1.  Thus, the leakage of refrigerant from the recessed part 23 of the slide valve disk to the hollow part 16 is prevented.

Title: Pressure regulating valve
Inventor: SUZUKI MOTOMITSU
IPC: E21C50/00
Filed: 1986-12-01
Abstract: PURPOSE:To make the pressure difference between the first and the second fluid at the time of closing valve operation less than that at the time of opening valve operation, by introducing the first fluid onto the valve seat side surface of a valve body. CONSTITUTION:It is so constituted that the one end side of a valve chamber 4 forms the first space chamber 6 communicating with the first fluid via a connecting pipe 5, and the other end side thereof forms the second space chamber communicating with the second fluid, and that both chambers 6 and7 are connected to a communicating space chamber 8. And the outside diameter d1 of a valve body 10 is formed so as to be sufficiently larger than the inside diameter d2 of a valve seat 9. In the opened valve condition, the pressure in the communicating chamber 8 is approximately equal to that of the second fluid, however, in the closed valve condition, the force acting on the valve body 10 becomes the value multiplied the pressure difference by the valve seat opening area, because the first fluid is introduced onto the valve seat side surface of the valve body 10 via the communicating chamber 8.
