Title: Rolling bearing
Inventor: ARAI KENJI
IPC: F16C33/78
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To accurately regulate the quantity of lubricating oil flowing inside of a ball bearing for a long time by making a predetermined quantity of the lubricating oil flow in the ball bearing through a throttle hole formed in a sealing. SOLUTION: A part of a core 11 constituting a sealing 10 is formed with at least one circular or elliptic throttle hole 15 to have both surfaces of the sealing 10 communicate with each other. The predetermined quantity of lubricating oil is made to flow in a ball bearing 1 through this throttle hole 15. With this structure, the quantity of the lubricating oil flowing inside of the ball bearing 1 can be desirably adjusted by changing area of the throttle hole 15 and changing the number of the hole (two or more holes are provided). Area of the throttle hole 15 can be accurately regulated, and this area is not changed even used for a long time. Consequently, quantity of the lubricating oil flowing in the ball bearing 1 can be regulated accurately for a long time.

Title: Fluorescent lamp apparatus
Inventor: HOTTA SHIGEMI
IPC: F21V7/00
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To save electric power by easily and reliably lighting only one lamp by providing a dummy tube including an energizing means having a small DC resistance component connected to opposed two connecting terminals among two pairs of connecting terminals installed between the other pairs of sockets among two pairs and connected to the sockets. SOLUTION: Opposed one sides of two contact pints P, P of a base-shaped part are connected between both end contact pins P, P of a dummy tube 20 by a single conductor 21, a current limiting capacitor C4 is connected to the middle of the conductor 21, and a discharging resistor R4 is connected in parallel to the capacitor C4. When lighting only one fluorescent tube 10, the other fluorescent tube is removed, and the dummy tube 20 is connected. When applying voltage on a transformer T of a ballast 30, the mutual contact pins P, P are connected by the conductor 21 in the dummy tube 20, and since the capacitor C4 is interposed in the middle of the conductor, a flowing electric current functions as a limited conductor. Thus, only one fluorescent tube 10 is lighted.

IPC: H04B7/26
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To optimize the retrieval frequency of a home network by a mobile station. SOLUTION: A mean value of a time interval from selection of a cell to selection of other cell again is calculated (S10). When an arithmetic value of a mean time interval for cell selection is a prescribed first value (e.g. 30min) or below, home network retrieval frequency corresponding to the calculated mean time interval of cell selection is decided (S14). On the other hand, when the mean time interval for cell selection is larger than the 1st value, a home network retrieval frequency corresponding to the 1st value is decided (S16).

Abstract: PURPOSE:To obtain a power generating plant having high responding capability to load variation by setting the supply amount of fuel to a reformer on the basis of load current and by controlling fuel gas flow rate to an auxiliary burner with differential pressure of a reformer reactor. CONSTITUTION:An arithmetic unit 22 sets fuel flow rate with a signal of a load current detector 21 connected to a fuel cell main body 9. A reformer supply fuel controller 23 compares a signal of a fuel flow rate detector 20 with the signal of the detector 21 by the instruction of the unit 22 and controls a flow rate control valve 2 so as to obtain the setting flow rate. Since the setting value of the fuel flow rate is larger than the total amounts necessary for power generation and a reformer burner, excess fuel is supplied to an auxiliary burner 15 through a bypass flow rate control valve B. A bypass flow rate controller 25 compares a signal of a differential pressure detector 24 which detects the inside and outside differential pressure of a reformer reactor with a target differential pressure and controls the valve 8. A power generating plant having high responding capability to load variation is obtained.

Abstract: PURPOSE:To prevent a wire body from breaking through simple constitution by guiding the wire body by many small-diameter guide rollers that an upper and a lower guide roller holder have and absorbing variation in payoff length through the upward/downward movement of the lower guide roller holder in a suspended state. CONSTITUTION:The front end of a guide tube 39 is aligned with the opening of a heat exchange pipe 3 and then the head part 5a of the wire body 5 is sent in a pipe 3 to be inspected. The lower holder 7 moves up slowly as shown by an arrow A simultaneously with said payoff operation to absorb the variation in payoff length. Then at the time the head part at the tip 5a of the wire body 5 finds abnormality in the pipe 3 and the feed is stopped, the driving motor for a caterpillar tread 36 is stopped. At this time, movable parts of a take-up and payoff device 1 are small-sized guide rollers 8, 9, and 8a and a lightweight, low-speed lower holder 7, so inertia is small, and an abrupt stop is possible and generates no external force upon the wire body 5. At the time of the wire body 5 is taken up, on the other hand, a feed mechanism C is only reversed.

Abstract: PURPOSE: To keep a motorcycle or the similar kind running at a constant speed by using a memory which puts out a signal as a command to form a closed loop until an instruction to change the speed is fed to connect the original value in the memory.  
     CONSTITUTION: One acceleration by an accelerator 28 closes switch 29 to put out a speed change instruction signal via an OR gate. A switch 20 is turned open so that an engine 23 increases in r.p.m on the accelerating instruction. As a conversion control circuit 31 puts out a comparative signal of an increment plus E, an up mode instruction signal UP is sent to a counter 11 of a memory 10. The counter 11 grows speed information up to a value, which is stored immediately before the accelerator is stopped to operate. When the accelerator seases, signals AB, UP become zero and the switch 20 is closed to form a closed loop for constant speed running. The engine 23 runs at a constant speed on data stored in the counter 11.
