Title: Disk automatic changer
Inventor: USUI TAKUMI
IPC: G11B17/28
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To provide a disk automatic changer for preventing the falling-off of a disk during transportation and surely and easily preventing the locking of a carriage. SOLUTION: When a CD as a disk is pulled out or pushed in by a carriage 26, a protect bar 40 is retreated from a CD transfer track by a protector 27. Thus, the CD is pulled out or pushed in. After the pulling-out of the CD or the pushing-in of the CD, the protect bar 40 is positioned on the CD transfer track by the protector 27. Thus, since the protect bar 40 is positioned on the CD transfer track, the falling-off of the CD is surely and easily prevented. While the protect bar 40 is positioned on the CD transfer track, the locking part 15 of a supporting section 14 and the engaging piece 47 of the protect bar 40 are engaged with each other and thereby the carriage 26 is locked. Thus, the carriage 26 is surely locked in synchronization with the protect bar 40 by a simple structure.

Title: Spacer discharging method and liquid crystal display element
Inventor: ISHIMARU NAOHIKO
IPC: G02F1/1339
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To accurately arrange spacers by using the ink-jet method and to manufacture a liquid crystal display element with a good productivity by using an ink mixed with a solvent having a boiling point of a specific value or higher and spacers, and heating a substrate temperature to a specific temperature or above. SOLUTION: This method for discharging granular spacers by using an ink-jet head 1 on a substrate 3, an ink prepared by mixing a solvent having a boiling point of >=100 deg.C and the spacers is used, and the spacers are scattered while heating the substrate to >=60 deg.C. By defining the boiling point of the solvent as >=100 deg.C the possibility of spacer discharge failure caused by volatilization and the reduction of the solvent near an ink-jet head nozzle is extremely reduced. As a result, stable discharge becomes possible for a long time. Moreover, the heating temperature of the substrate should be 60 deg.C or higher, and the effect is large if the substrate is heated to -40 deg.C to 130 deg.C higher than the boiling point of the solvent.

Title: Device for discharging dust or the like of bag filter
Inventor: MURAMATSU KEISUKE
IPC: B01D46/48
Filed: 1993-03-03
Abstract: PURPOSE:To provide a device of preventing the effect that a bridge occurs in dust and dust does not fall on a screw conveyor by providing a stop valve by which the inside and outside of a filter chamber can be communicated with each other or cut off from each other. CONSTITUTION:When dust D deposited in the bottom part of a hopper 30 is wet or has not a smooth shape, its fluidity is lowered, and the dust is stored in a hopper to cause bridge and does not fall on a screwed bar 33. A means 40 for eliminating the bridge is constituted of a stop valve 42 and a controller 44 for opening and closing the stop valve 42 properly. For example, when the hopper 30 is set to pressure a little lower than the atmospheric one and the stop valve 42 is opened, the air flows in the hopper through an opening, a valve hole and a vent hole to increase its pressure, and the instant the stop valve 42 is closed, the air is discharged to the outside by a fan to return the pressure to the original one. When the stop valve 42 is thus intermittently opened and closed by a controller 44, fluctuation in pressure in the hopper 30 causes dust constituting bridge to be vibrated and broken down.

Title: Control method for feedback of injection timing in diesel engine
Inventor: IKEDA SHINJI
IPC: F02B3/06
Filed: 1983-05-11
Abstract: PURPOSE:To prevent erroneous operation by controlling the fuel injection timing in accordance with the number of revolutions and the load of an engine in case the difference between a target ignition timing and an actual ignition timing is over a fixed value. CONSTITUTION:In an electronic control circuit 5, the fuel injection timing is set on the basis of the number of revolutions and the load of an engine in case the time from when a piston is at the top dead center to the actual ignition time is over a fixed time. That is, a target ignition timing is obtained to obtain a difference from a detected ignition timing. Then, whether the deviation is over a fixed value or not is decided. When it is over the fixed value, the feedback control is intercepted, and the fuel injection timing is controlled in accordance with the number of revolutions and the load of the engine. This construction permits to prevent the erroneous operation even if some abnormality is caused in an ignition timing detection means.

Title: Current inverting circuit
Inventor: ETOU TOSHIYUKI
IPC: H03F3/347
Filed: 1980-06-18
Abstract: PURPOSE:To reduce the deterioration of Miller ratio and to increase the accuracy of input and output current transfer, by commonly using an operational amplifier to a current Miller circuit of opposite polarity through independent current Miller circuit from a signal system of a bias circuit. CONSTITUTION:The current Miller at the input stage is operated as an active load, and an operational amplifier 13 at the output stage constitutes a current Miller circuit of opposite polarity from said current Miller circuit. Further, in an integrated circuit, although wrong characteristics are only obtained for PNP transistors (TR)1, 2, the increase/decrease of the collector current due to a low output impedance of PNP due to power supply variation can be cancelled internally and cannot appear at the output, by matching the VCE of pair TRs in the current Miller circuit without being affected by a low early voltage. Thus, the power supply variation suppression ratio can be very greater. Further, since the effect of due to a low current amplification factor is zero because the bias current is supplied entirely independently of the signal system.

Abstract: PURPOSE:To flatten frequency characteristics of the entire delay time and to reduce the rotation of phase by connecting stages of IC-implemented delay elements used in a ghost eliminator, etc., for TV and by giving adjacent delay element complementary delay characteristics. CONSTITUTION:Voltage gains of transistors (TR)4 and 5 of a delay element D1 is 1, and out-of-phase voltages developed between the emitters and collectors of the TRs 4 and 5 respectively when a signal is inputted to a terminal 13 are added together through resistances R and capacitors C to further output a cascaded delay signal to a terminal 21. Elements D1, D2, D3... of this constitution are connected as stages to constitute a delay circuit. Different coupling resistances Rf and Rf' are used between the element D1 and D2, and D3 to compensate frequency characteristics of delay times between the elements D1 and D2, and D2 and D3, and then frequency characteristics of the entire delay time are flattened while the rotation of phase is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus capable of automatic level setting by setting a tripod in the case of survey or the like, improve efficiency and precision of survey, and improve installation work by automatic level setting in the case of installation of a machine tool or the like. SOLUTION: A weight 3 including a light emitting element is fixed to the lower end of an optical waveguide 4 via a free holding tool 2. The optical waveguide 4 always indicates the vertical direction. A light outputted from the optical waveguide 4 forms an optical image on a photoelectric element 1 attached on the lower surface of a movable plate 10. The position of the optical image when the movable plate 10 becomes horizontal is previously specified, and the position is set as a horizontal state reference point. In principle, this may be done once at the time of manufacture. When the movable plate 10 is inclined from the horizontal state, the optical image moves on the photoelectric element 1. By correcting the movement with two servo machanisms, the optical image is returned to the horizontal state reference point.  Thereby the movable plate 10 can be returned to the horizontal state.
