Title: Current detector of inverter apparatus
Inventor: UEDA HIDEFUMI
IPC: H02M7/5387
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To attain a current detector of an inverter apparatus that requires voltage resistance of about 600 V or higher between a current detecting value sending side and receiving side by providing a gate drive circuit for turning ON and N-channel power MOSFET depending on a command transmitted from a control unit. SOLUTION: A comparator 23 as a control unit compares an output of an operational amplifier 22 with a drain voltage of an N-channel power MOSFET 36. When the drain voltage value is lower, an output side transistor 24 (b) as a gate drive circuit of the MOSFET 36 turns ON to lower the gate voltage of the MOSFET 36. As a result, the channel resistance of the MOSFET 36 increases and the drain current reduces. Moreover, when the drain voltage value is higher, the output side transistor 24 (a) of MOSFET 36 turns on and the gate voltage of the MOSFET 36 rises. As a result, the channel resistance of the MOSFET 36 reduces and the drain current increases.

IPC: G02B6/00
Filed: 1986-09-02
Abstract: PURPOSE:To obtain an elastic cylindrical light emitting body by forming an optical fiber into a coil to generate a leaked light in bending parts. CONSTITUTION:The light made incident on one end 2 of a coiled element 1 is leaked in bending parts of the element 1 on the way of transmission in the optical fiber. The leaked light is increased according as the diameter of the optical fiber forming the coiled optical fiber element is thicker and a coil pitch T and a coil diameter R are smaller. Plural coiled optical fiber elements 1 are combined to form a cylindrical body, thus obtaining the elastic cylindrical light emitting body. Thus, the very variant light is emitted regardless of the simple structure, and this light emitting body can be used not only as a display mark but also as a shape memorizing light emitting body if optical fiber elements are formed into a desired shape and are thermally fixed.

Title: Cut supplying device
Inventor: MASAKI OSAMU
IPC: B25J15/06
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To correctly pull out piled cups one by one so as to prevent a supplying error from being made by changing the inner diameter of a holding tool and attaching a suction tool to a vertically moving and inverting device. SOLUTION: A vertically moving and inverting device is raised and a suction tool 2 is brought into contact with the bottom 13 of a cup 10. In this case, space air is sucked by an air pipe 9 simultaneously when the suction tool 2 is brought into contact with the bottom 13, the inner diameter of a rubber hose is expanded and cups 10, 10,... likely to fall are placed on the suction tool 2 and supported. When air is sucked through an air hose, the bottom 13 of the cup is sucked to the suction tool 2 (right side). The vertically moving and inverting device is lowered after the cups 10 are sucked. In this case, only the cup 10 in the lowermost end must be pulled out from the cups 10 piled in the upper side and, consequently, the inner diameter of the rubber hose is reduced and the hose is brought into contact with the cups 10 and 10.  Thus, only the cup 10 positioned in the lowermost end is pulled out by the suction tool 2 (left side).

IPC: C08L69/00
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To obtain a high transmittant, luminous resin showing high afterglow by mixing specified amounts of phosphorescent pigments having different particle diameters with a resin. SOLUTION: This resin is prepared by mixing or incorporating 1-4 wt.% resin 1 with a phosphorescent pigment 2 (e.g. SrAl2O4: Eu, Dy) having a particle diameter of 20 μm or above and at least 1 wt.% phosphorescent pigment 2 having a particle diameter of below 20 μm. The total content of the phosphorescent pigments should be 1-4 wt.%. The resin 1 is exemplified by a transmitting resin such as a polycarbonate, an acrylic resin, a polypropylene, an AS resin, a vinyl chloride resin, a polystyrene, a urethane resin, or a polyethylene. As a result, the resin can give a molding which still retains phosphorescence and can permit the one to perceive the side beyond the visually recognized side.

Title: Controlling method for branch hydraulic circuit
Inventor: KUROKI MASAKI
IPC: F15B11/16
Filed: 1991-07-23
Abstract: PURPOSE:To simplify lining between hydraulic equipments by setting a pressure value of a relief valve to a specified high value when a value detected by a pressure detector is not more than a lower side reference value, and by setting it to be a specified low value when the detected pressure is a higher side reference value or more, under a condition that a changeover valve is set to be a neutral position. CONSTITUTION:In case that a controller 4 detects that a changeover valve 15 is set a neutral changeover position 15A by means of a position detector 4a, also detects a pressure of an accumulator 6b by means of a detector 4b, and judges that the detected pressure is not more than a lower side reference value, a pressure set value of a relief valve 7 is highly set. Under such a condition, a pressure oil is charged into the accumulator 6b from a hydraulic pump 1 through a discharge pipe passage 1a, a check valve 6, and a pipe passage 6a. When the hydraulic pressure is a higher side reference value or more, the pressure set value of the relief valve 7 is set to a minimum with which the valve is opened. As 21 result, the pressure in the discharge pipe 1a and a main hydraulic pipe passage 1c is lowered. The high hydraulic pressure charged in the pipe passage 6a closes the check valve 6, to prevent contraflow of the pressure oil.

Abstract: PROBLEM TO BE SOLVED: To eliminate lens vibration and to attain access of high precision by adding a simple circuit to a usual optical system of an optical pickup and constituting a negative feedback loop so as to make the optical axis of the lens align the optical axis center of the optical system. SOLUTION: A focus detection signal is obtained by combining light receiving surfaces 7a-7d in a form of (7a+7b)-(7b+7d), and making an output signal (a+c)-(b+d).
