Title: Sealing device
Inventor: ABE YOSHIYUKI
IPC: F16J15/3236
Filed: 2001-03-16
Abstract: PROBLEM TO BE SOLVED: To enhance a durability by effectively preventing a projection of a seal body at high pressure without increasing a cost and an installment space. SOLUTION: A projection 22 contacted with a corner part 32b of a mounting groove 32 of one member 3 is formed on an end surface 2a of a backup ring 2. The backup ring 2 is inclined with a good responsiveness making the projection 22 as a fulcrum by an axial load F from the seal body receiving a pressure and a gap δ1 between the backup ring 2 and the other member 4 is shrunk. Therefore, the projection of the seal body to this gap δ1 and a 'bitten' caused by this are effectively prevented. In the case where a pressure rise is relatively large, the gap δ1 is buried by falling down of the projection 22 and displacing the backup ring 2 to the other member 4 side.

Inventor: SATO SHINICHI
IPC: G01S13/86
Filed: 2001-03-21
Abstract: PROBLEM TO BE SOLVED: To provide an obstacle detecting system capable of highly precisely detecting an obstacle in the circumference of a vehicle in a short time. SOLUTION: This obstacle detecting system is provided with a visual field range determination means determining a visual field range 2a of a driver 2 of a vehicle 1 and a transmission wave control means determining the radiation range or the shape of the beam of the transmission wave based on information from a visual field range determination means so that the sensing range 3a of a sensor 3 can be narrowed so as not to stack with the visual field range 2a of the driver 2, thereby shortening a period of the sensing and quickening the updating time of data. When the sensor 3 receives a reflected wave from a material, the transmission wave is radiated only in the direction near the material or the material direction or the beam width of the transmission wave radiated in the direction is reduced so that detailed information related to the material can be obtained in a short time.

Title: Variable nozzle type hydrostatic bearing
Inventor: YOSHIMOTO SHIGETAKA
IPC: F16C32/06
Filed: 2001-03-27
Abstract: PROBLEM TO BE SOLVED: To control damage and wear between a movable object and an inner wall of a bearing main body caused by a collision and contact between the movable object in which an oriffice is formed and the inner wall of the bearing main body and also to secure smooth motion of the movable object. SOLUTION: Fluid flowing into a third fixed oriffice 38 flows out to a side pocket 36 and then flows into a clearance 32. The fluid flowed in to the clearance 32 forms a fluid film between the inner wall of an upper portion 10A of the bearing main body and the movable object 14. The fluid film becomes buffer material when the movable object 14 keeps in contact with or collides with an inner wall surface of the upper portion 10A of the bearing main body. Thus, the upper portion 10A of the bearing main body and movable object 14 can be protected from wear and damage.

Title: Information providing method to phs terminal in service area, its program and computer-readable recording medium for recording the program
Inventor: KUROBE TAKAO
IPC: H04W12/08
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for providing information to a PHS terminal in a service area with a reduced communication cost and enhanced security. SOLUTION: An authentication center 12 discriminates whether or not a PHS terminal 2 in a service area makes a call to a contents providing server 3 contained in a base station in the area and informs the base station 1 about the result of discrimination.

Abstract: PROBLEM TO BE SOLVED: To provide a photoelectric sensor, capable of successively transmitting a synchronizing signal to a low order photoelectric sensor, without accumulating deviations due to microcomputer processing in each photoelectric sensor at adjacent arranging of a plurality of photoelectric sensors. SOLUTION: Whether or not a reception synchronizing signal Si is received is determined, and each time the reception synchronizing signal Si is received, a reception frequency T is measured (steps S1 and S2). The size of the reception frequency T is compared with that of a preliminarily stored reference frequency (a step S3). The reference frequency is set by storing the reception frequency of each photoelectric sensor 10 at successive transmitting of the synchronizing signal from the first photoelectric sensor, at the time of power supply. When they are agree with each other, a light projection signal St and a transmission synchronizing signal So are outputted posterior to a normal timing (10 μs) (steps S4 and S7). In the other case, a frequency different D is calculated, and a wait time B is corrected (steps S5 and S6).
