Title: Ground protection circuit of discharge lamp lighting circuit
Inventor: UDA RYOICHI
IPC: H02H3/20
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a ground protection circuit being easy to manufacture and easily and surely detecting grounding. SOLUTION: In an inverter type discharge lamp lighting circuit, copper foil 69a, 69b is affixed to the magnetic core 62 of a transformer 11 and is connected to the common potential point 97 of the circuit via a resistance element 68. The high-frequency high voltage of a secondary winding 56 is induced in the magnetic core 62 via an electrostatic capacity between the secondary winding 56 and the magnetic core 62 and this induced voltage is applied to the resistance element 68.  Under normal conditions, a voltage about the mid-point of the winding 56 and proportional to, e.g. ±4 kV, is induced in the magnetic core 62, but if a discharge lamp 23 or its wiring is grounded, one end of the winding 56 on the grounded side has a zero voltage and the other end has a voltage of ±8 kV, so that a voltage proportional thereto is induced in the magnetic core 62 and rectified and smoothed and becomes greater than the reference voltage VS of a comparator 77. Then the output of the comparator 77 attains a high level and a thyristor 86 is turned on to stop oscillation of an inverter 55.

IPC: H04B10/29
Filed: 1990-09-28
Abstract: PURPOSE:To monitor a state of each section by means of an optical signal during in-service by sending a check optical signal to an optical transmission line and reflecting part of the signal at an optical direct amplifier type optical repeater. CONSTITUTION:A communication optical signal whose wavelength is lambdao and a check optical signal whose wavelength is lambdao+DELTAlambda are sent from one terminal station 1 to an incoming optical transmission line 4 and a communication optical signal whose wavelength is lambdao and a check optical signal whose wavelength is lambdao-DELTAlambda are sent from the other terminal station 2 to an outgoing optical transmission line 5. An optical direct amplifier type optical repeater 3 branches part of the check optical signal and synthesizes it to the optical transmission lines 5, 4 and reflects the result to the terminal stations 1, 2. The reflected check optical signal is arranged in a time interval corresponding to the distance of the optical transmission line between the optical repeaters 3 with respect to the transmission timing of the sent check optical signal in the terminal stations 1, 2. Thus, the state of the optical transmitters 4, 5 and the optical repeater 3 are monitored during in-service based on the reflected check optical signal.

Title: Automatic power varying camera
Inventor: MOMOSE HARUHIKO
IPC: G03B5/00
Filed: 1985-11-19
Abstract: PURPOSE:To photograph securely a subject image of desired size from a subject in motion without missing a shutter chance by switching focal lengths of a variable power lens automatically on the basis of information on the distance to the subject and obtaining the photograph of proper size. CONSTITUTION:When the subject at short distance, a range finding signal VAP is larger than VN so both comparators COMP1 and COMP2 output 0 and the variable power lens 4 is moved to its short focus side, so that a photographed image of the subject is not large. Then when the subject is at intermediate distance, MM<VAP<VN so the comparator COMP1 outputs 1 and the comparator COMP2 outputs 0. Consequently, the variable power lens is switched to its long-focus side to prevent the photographed image of the subject from becoming small. When the subject is at long distance, the range finding signal is lower than VF, so both comparator COMP1 and COMP2 output 1 and the focus of the variable power lens 4 is unchanged.

Abstract: PURPOSE:To relieve regulating work even for a load circuit to be driven with a low voltage power supply by connecting each power supply unit through a FET transistor with a corresponding load circuit and arranging a shunt regulator for controlling the gate voltage with the output voltage from the power source unit in each switch circuit. CONSTITUTION:A power supply unit comprising a voltage stabilizing section 2a and a switch circuit 5a and another power supply unit comprising a voltage stabilizing section 2b having identical circuitry and a switch circuit 5b are connected in parallel, and then one input power supply 1 and a load circuit 4a constituting an exchange are connected therewith. When the voltage at a terminal 21 drops below a predetermined level, a shunt regulator circuit 24 turns a transistor 11 OFF and interrupts the connection between the terminals 21, 22. The shunt regulator circuit 24 controls the gate voltage of the FET transistor 11. By such arrangement, regulation work can be relieved even for a load circuit to be driven with a low voltage power supply.

Filed: 1993-10-15
Abstract: PURPOSE:To securely compact the edge of a pavement by use of a simple structure. CONSTITUTION:A mounting bracket 4 is fixed at the end of a screed 1. An end plate 11 is attached through a bolt 16 and a fitting plate 17 so as to be vertically movable, in the vertical slide hole 9 provided in the attaching bracket 4. A belleville spring 19 for buffering action is equipped between a guide bar 15 fixed to the end plate and the attaching bracket. The lower half of the end plate shapes a slanting form 13 expanding both downward and outward. When a vibrator 21 equipped on the end plate generates vibratory motion, the end plate oscillates vertically. The perpendicular force against the face which is given by the slope of end plate against the edge of pavement 2 laid down by the screed, is larger than the vertical force by the end plate and hence, the edge can be securely compacted.

Title: Engine with extension oil pan
Inventor: HIDA KOICHI
IPC: F01M11/00
Filed: 1994-10-25
Abstract: PURPOSE: To prevent the occurrence of air accumulation in an extension oil pan by providing an air guiding wall in the extension oil pan, and letting the lower end opening section of an air vent pipe be faced to the air guiding wall from above. CONSTITUTION: The extension oil pan 2 is detachably fixed to the lower side of the oil pan 1 of the engine E. The oil pan 1 is communicated with the oil running port 7 of the extension oil pan 2 through an oil circulating path 5. An air guiding wall 8 is provided in the extension oil pan 2, and set in an upward inclined shape toward the oil running port 7. When oil is fed to the oil pan 1 at the time of oil replacement, oil flows in down below the air guiding wall 8 by way of the oil running port 7 through the oil circulating path 5. Air rolled in oil comes up to the surface, is guided to the upward inclined direction along the lower surface of the air guiding wall 8, and it smoothly gets out into a crank case by way of the oil circulating path 5 through the oil running port 7.  This constitution thereby enables the engine to be continuously operated for a long time with the quantity of oil assured properly.
