Title: Anticollision control method for magnetic levitation carrier
Inventor: AOMORI NAOTO
IPC: B60L13/06
Filed: 1990-08-21
Abstract: PURPOSE:To prevent collision by receiving a signal transmitted from another carrier, when one magnetic levitation carrier approaches another carrier within a predetermined distance, and outputting a signal for controlling a magnetic levitation circuit to attract the body to a track. CONSTITUTION:Truck l of a magnetic levitation carrier is provided with four levitation coils 4 and gap sensors 6 on the right and left in front and rear and a baggage table 3 is supported in cantilever by means of an L-type arm 2. A levitation coil 4 is energized by a command provided from a control section(not shown) and floated to a predetermined gap and the primary coil 11 of a traveling rail 10 is also excited thus advancing the truck l along a rail 12. When a light receiving section 8 of the truck l detects that the magnetic levitation carrier approached to another carrier within a predetermined distance, the control section transmits a signal for de-energizing the levitation coil 4 to the light receiving section 9 of the truck l based on thus detected signal thus attracting the truck l to the rail 12. Consequently, collision is prevented and the baggage on the table 3 is protected against damage.

Title: Dc-stabilized power supply
Inventor: DOI KAZUO
IPC: H02H3/20
Filed: 1991-09-03
Abstract: PURPOSE:To prevent any rupture of a load by providing an abnormal voltage detector for detecting any broken wire in sense line and a disconnecting circuit for disconnecting the load from an output voltage controller when the abnormal voltage detector detects any broken wire in the sense line. CONSTITUTION:If a sense line 2 has a broken wire, then an output voltage feedback portion 7 becomes unable to normally detect the output voltage from a output voltage controller 8, so that the output voltage of the output voltage controller 8 is raised. Because of this, a high voltage is supplied to a force line 3, and the high voltage is applied to a load 4. At this time, an abnormal voltage detector 1a of the sense line detecting circuit 1 sends out an output signal to an output break controller 1b, the output break controller 1b receives a signal from the abnormal voltage detector 1a, and relay contacts 6a and 6b are turned into off state. By doing this, any application of a high voltage to the load can be prevented.

Title: Flat plate type picture display device
Inventor: NONOMURA KINZOU
IPC: H01J31/12
Filed: 1982-12-20
Abstract: PURPOSE:To exceedingly reduce the number of secondary electrons that arrive at a screen plate and obtain a clear picture by comprising an electrode group so that the size of the electron beam passing hole of one electrode near a linear cathode can be larger than that of the electron beam passing hole of the other electrode. CONSTITUTION:The size of the electron beam passing hole of one G1 electrode 43 near a linear cathode 42 is larger than that of the electron beam passing hole of the other G2 electrode 44. In the electrons emitted from the linear cathode 42, electrons 45 that are incident on the G1 electrode 43 and collide against it are emitted as part of secondary electrons and most of them are caught by the G2 electrode 44. In addition, electrons 46 that pass through the electron beam passing hole are focused by a lens system that is comprised with the G1 and G2 electrodes 43 and 44 and the number of electrons that are incident on and collide against the G2 electrode 44 is exceedingly reduced. As a result, the quantity of secondary electrons emitted by the electrons that are incident on and collide against the G2 electrode 44 is exceedingly small as compared with the case of the G1 electrode 43. Since the electron beam passing hole of the G1 electrode 43 is made larger, the lens effect with the G2 electrode 44 can be increased further and a focusing effect can be improved.

Title: Piston for internal combustion engine
Inventor: SUZUKI YOSHIHIRO
IPC: F16J1/01
Filed: 1988-09-07
Abstract: PURPOSE:To prevent the occurrence of a trouble, e.g. crack, by a method wherein composite reinforcement is effected so that the volume rate of a porous metallic substance formed such that chrome of at least a specified % or more is contained is in a range of a specified %, and chrome is formed in a thickness of specified mm or more on the surface part of the porous metallic substance. CONSTITUTION:In an aluminum alloy piston 1 for an internal combustion engine in which composite reinforcement is made on a link groove 2 by using a porous metal, composite reinforcement in 8-70% volume ratio is applied on a porous metallic substance formed such that chrome of at least 10% or more is contained. The chrome is formed in a thickness of 0.001mm or more on the surface part of the porous metallic substance. This constitution prevents formation of a brittle intermetallic compound due to reaction between aluminum and a reinforcing substance, resulting in prevention of the production of a crack at an intermetallic compound and improvement of wear resistance.

Abstract: PURPOSE:To stabilize a transmission operation by setting up specified relation among the threshold voltage VT1 of one of two logic inversion circuits and the logical threshold voltage VT2 at the time of rising the input voltage and the logical threshold voltage VT2D at the time of falling the input voltage of the input terminals of the other logic inversion circuit. CONSTITUTION:The relation of VT2D>VT1>VT2R is set up among the logical threshold voltage of VT1 of the input terminal of a first inverter 1, and the logical threshold voltage VT2R at the time of rising the input voltage and the logical threshold voltage VT2D at the time of falling the input voltage of the input terminal of a second inverter 2. The input voltage V2 of the second inverter comes equal to VT2D at the point of time t2 at the fall, then, is inverted, and at the point of time t3 at the next rise, it comes equal to VT2R, and is inverted. In both cases, since both a rising waveform and a falling waveform are surely inverted before reaching the threshold voltage VT1, the stable output voltage Vo of a rectangular waveform with a high level value H and a low level value L can be obtained at an output terminal To.

Abstract: PURPOSE:To prevent the fall of input impedance by providing a differential amplifier with first and second input terminals, constituted of a pair of transistors(TR), and a constant current source circuit, and giving an alternating current signal to the first input terminal, and at the same time, connecting it to the constant current power source circuit, and impressing a bias voltage to the second input terminal. CONSTITUTION:The TRs 1A-2C constitute a current mirror circuit 23, and said current mirror circuit 23 and a TR IC and the constant current source 22 constitute the constant current source circuit 24. Said circuit 24 generates always a current equal to the current to flow in the input terminals 13, 17 when the voltages of those input terminals are equal.

At that time, the bias voltage of the input terminal 13 is given by the constant current source circuit 24, and the fall of the input impedance owing to that a bias circuit is provided in the differential amplifier 10 comes to be zero.
