Title: Hid lamp inverter circuit
Inventor: MIYAJIMA MASAYOSHI
IPC: H05B41/24
Filed: 1989-07-18
Abstract: PURPOSE:To prevent an overcurrent to transistors of an inverter when a lamp is disconnected by vibration or the like by providing a switch which stops the drive of an inverter circuit or Turns it in no load state when no HID lamp current is detected. CONSTITUTION:When a power source AC is turned on, a start circuit 13 detects it, a switch 12 is turned on, the DC voltage is applied to a bridge inverter 3, and the resonance voltage is applied across both ends of an HID lamp 6 connected to the primary winding of a transformer 11 via a starting capacitor 5 by switching actions of transistors 30 and 31 to light it. The voltage is generated on a rectifying circuit 14 to keep the switch 12 on. When the lamp 6 is disconnected while it is lighted, the output voltage of the circuit 14 via the transformer 11 is made zero, the switch 12 is turned off, and the operation of inverter 3 is stopped. An overcurrent is prevented from flowing in the inverter 3 using the capacitor 5 as a load.

Title: Servo control method and servo controller
Inventor: INOUE HIDEAKI
IPC: G05D3/12
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To stop a device at a stop position with the command of zero volt of speed command voltage in an analog servo by ignoring a speed command with a position holding signal, providing a position loop in the servo amplifier and controlling stop with the position loop. SOLUTION: A servo controller 1 receives the speed command with a voltage command transmitted from an NC device 2, controls speed and executes position control for stopping the device at the prescribed position with the position loop formed by the positron holding signal 22. Speed control by the speed command and position control by the position loop are changed over by the control mode switch means 11 of the servo controller 1. Speed control by the speed command is to input the voltage command 21 from the NC device 2 through a control mode switch means 11, to form driving current corresponding to the voltage command 1 by the mechanism of a regular servo amplifier and to supply it to the servo motor 3. The speed command is ignored and the position loop stops the device in the prescribed position so as to hold it in the position.

Title: Sequential open/close construction of two open/close valves
Inventor: MITSUOKA JUICHI
IPC: F16K35/00
Filed: 1990-07-12
Abstract: PURPOSE:To ensure the prevention of a water hammer phenomenon, and the possibility of the sequential speed of two liquids by arranging both open/close valves according to such a positional relationship as disabling the opening or closing operation of either valve in a sequence other than specified, due to the interference of a lever and a valve spindle, when the valves are in a specific open or close condition. CONSTITUTION:When both a main open/close valve 3 and a sub-open/close valve 4 are wide open for allowing a maximum flowrate. Also, when the sub- open/close valve 4 is open, the main open/close valve 3 can be freely opened and closed, thereby changing a flowrate from a minimum level to a maximum level. A pipe line in operation is used in the aforesaid state. Also, when a valve spindle 5 is being lifted, a lever 6 comes in contact therewith. The closing operation of the sub-open/close valve 4 is disabled, and it is always required to close the main open/close valve 3 before closing the sub-open/close valve 4. In this case, when the main open/close valve 3 is totally closed, the sub-open/ close valve 4 is still open, and there is a certain flow through the valve 4. No water hammer phenomenon, therefore, does not appear.

Title: Transistor inverter
Inventor: INUI KENICHI
IPC: H02M3/338
Filed: 1980-12-26
Abstract: PURPOSE:To enable the utilization of the output from a drive circuit as the power of a control circuit by breaking the drive circuit for an inverter at its malfunctioning time. CONSTITUTION:When a discharge lamp 15 becomes malfunction state such as half-wave discharge or the like, an abnormal voltage is produced at the secondary coil 16, and is in turn presented at the abnormal detecting coil 54. The abnormal voltage is then rectified by a rectifier 55, and is applied to a Zener diode 60, thereby allowing the diode 60 to be conducted. The diode 60 thus charges a capacitor 63 with the current, thereby conducting a transistor 53. Simultaneously, a signal is supplied to a base control circuit 43 to close an inverter circuit, thereby interrupting a transistor 42. In this manner, the output interrupting a transistor 42. In this manner, the output side of a soft start circuit 41 is shortcircuited. Thus, the oscillation of the inverter 11 is stopped, thereby allowing a discharge lamp 15 to be deenergized. Since the charge of the capacitor 73 of the power source 71 is not discharged but is maintained in this manner, the operating voltage can be supplied to the control circuit 65 even while the inverter 11 is stopped.

Title: Surface acoustic wave device
Inventor: AMANO HIROYUKI
IPC: H03H9/145
Filed: 1994-07-15
Abstract: PURPOSE:To prevent adverse effect by spurious radiation in the lateral mode by selecting an interval of bus bars of a transducer and a reflector opposite to each other to be an interval not coincident with an integer multiple of a wavelength with respect to the operating frequency. CONSTITUTION:A bus bar 1 and a ground side bus bar 2 acting like transducers and connecting to an input terminal/output terminal are provided onto a piezoelectric substrate. Input or output side electrode fingers 3 of th bus bar 1 connecting to the input terminal or the output terminal are opposite to ground side electrodes 4 with a prescribed gap. Then the interval L1 between the bug bar 1 and the ground side bus bar 2 opposite to each other and connecting to the input terminal/output terminal is selected so as not to be coincident with an integer multiple of a wavelength lambda with respect to the operating frequency. That is, the relation of L1not equal to n.lambda is in existence, where (n) depicts an integer. The best result is obtained by selecting the L1 to be (n+5/8lambda) according to experiments. Thus, the occurrence of a standing wave of the surface acoustic wave in the lateral mode between a couple of the bus bars 1, 2 is prevented.
