Title: Fuel tank
Inventor: SOMA SATOSHI
IPC: F02M37/00
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent the fuel remaining in a lower curved portion of a breather pipe of a fuel tank from disturbing oil supply by an oiling gun. SOLUTION: A breather pipe 13 of a fuel tank T has a lower curved portion 132 formed midway to prevent interference with a vehicle frame 16. The lower curved part 132 of the breather pipe 13 and a filler pipe 12 are communicated via a communication passage 17 so that the fuel remaining in the lower curved part 132 is discharged to the filler pipe 12 by gravity. Thereby, it is possible to prevent an oiling gun G from unnecessarily stopping automatically, caused when upper space of a tank body 11 is sealed by fuel remaining after oiling and thus the fuel level inside the filler pipe 12 rises, or when fuel remaining in the lower curved portion 132 is pushed to an oil filler port 121 of the filler pipe 12 due to pressure increase during oiling in the upper space of the tank body 11.

Filed: 1993-08-18
Abstract: PURPOSE:To surely insert a ferrule to an optical connector housing by easily aligning respective whirl stop structures of the connector housing and the ferrule at the time of automatic assembling of an optical connector plug. CONSTITUTION:When a ferrule 1 provided with a flange 13 having a polygonal section is inserted to a housing 2, a projecting part 13a of the flange 13 comes into contact with a slope face 23 on the ferrule entrance side of a ferrule whirl stop structure 22 in the housing 2.

Title: Heat pump type heating apparatus
Inventor: TOKUDA HIROBUMI
IPC: F24F11/02
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a heat pump type heating apparatus which enables quick elimination of a state of excessive temperature at the time when a room temperature rises to this state in a floor heating operation. SOLUTION: At the time when a room temperature thermostat-off state, i.e., a state wherein a room temperature is higher than a set room temperature TSA, continues for a prescribed time t1, a control to lower a set floor temperature TSF in a drop range ΔTF corresponding to a temperature difference ΔTA between the room temperature and the set room temperature TSA is executed. Thereby a state of excessive temperature can be eliminated more quickly by one change of the set floor temperature even when a rise range of the room temperature is relatively large due to the heat of direct rays of the sun or that of a kitchen. Besides, the change of the set floor temperature is conducted at the time when the state of excessive temperature continues for the prescribed time t1, but not conducted in such a case when a detected room temperature rises momentarily. Therefore no useless drop of the room temperature takes place and comfortableness is maintained.

IPC: G01R31/12
Filed: 1988-08-17
Abstract: PURPOSE:To perform exact discrimination without using an expensive constant- voltage power source, by counting a pulse signal from a detecting means and by discriminating the occurrence of a corona discharge when the pulse signal is generated at the value more than prescribed for a unit time. CONSTITUTION:When a corona discharge occurs in a primary coil 1a of a pole transformer 1, a change in voltage appears in secondary coils 1b and 1c, a current pulse flows through a low-tension distribution line 1c and a change in magnetic flux occurs around the line. Thereby a current flows through an air-core coil 5, an electromotive power generated by an electromagnetic induc tion action thereof is given as a detection signal to a counter 8 through an amplifier 6 and a band-pass filter 7, and the number of discharges is thereby counted. Since the corona discharge occurs in large numbers in every time in proximity to positive and negative peak voltages of a line frequency on the occasion, the corona discharge is judged to occur when the detection signal is counted by a prescribed value, e.g. 500 to several K discharges/sec., in the counter 8. An indicating element 9 is driven by an output signal of the counter 8 on the occasion, and the occurrence of the corona discharge is indicated by a lamp/buzzer.

Filed: 1987-08-18
Abstract: PURPOSE:To prevent characteristic deterioration in a digital line by providing a circuit detecting out of synchronism of a PLL circuit and a circuit interrupting the output of a compensation circuit by the detection signal of the circuit. CONSTITUTION:An out of synchronism detecting circuit 1 detects the out of synchronism detecting circuit of a PLL circuit 20 to output a detection signal (d), and a compensation signal disconnecting circuit uses the detection signal (d) of the circuit 1 to output a control signal C disconnecting the compensation signal being an output of the compensating circuit 30.
