Title: Field emission type electron gun
Inventor: KAI MIKIAKI
IPC: H01J37/073
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To automatically control a lead-out voltage and prevent discharge between the lead-out electrode and an emitter and prevent emitter loss by detecting an ion current of an exhaust ion pump and providing control means for controlling output of a lead-out voltage power supply based on its result. SOLUTION: When operation for generating electron beams is performed from an electric field emission type electron gun(FEG) 10, an ion current detector 5 continuously detects an ion current flowing an exhaust ion pump 16 and imparts it to a base of a limiter transistor Q8. When degree of vacuum in the vicinity of an emitter 11 is worsened, an ion current flowing the exhaust ion pump 16 increases, and yields of the ion current detector 5 also increases. When this current is beyond a certain value, the limiter transistor Q8 is turned on by yields of the ion current detector 5. Thereby, auto control of the lead-out voltage or the like is made possible.

Title: Controller
Inventor: SONODA YOSHITERU
IPC: F16K31/44
Filed: 1989-03-22
Abstract: PURPOSE:To permit an upper circle board to race and to prevent the damage of a controller owing to the over-tight of a handle by permitting the upper circle board to ascend in resisting the force of a spring when a rotary torque which causes the handle to rotate comes to a prescribed torque, and causing a ball to escape from a concave part. CONSTITUTION:When the handle 31 at the protruding end of a stem 17 is rotated, the rotation is transmitted to the upper circle board 38 by a connection pin 35, and the upper circle board 38 rotates in the same direction as the handle. Then, the rotation is transmitted to a lower circle board 43 by the ball 42 and the lower circle board 43 rotates in the same direction as the upper circle board 38 with the stem 17. When the controller is closed, the rotation of the stem 17 stops and accordingly the rotation of the lower circle board 43 stops. When the handle is caused to rotate from such a state, the upper circle board 38 is ascended against the force of the spring 37, and the ball 42 escapes from the concave part. Thus, the upper circle board 38 races and the rotary force is prevented from being transmitted to the lower circle board 43. Then, the torq more than the prescribed one does not come to operate, and the damage of the controller owing to the over-tight of the handle is prevented.

Title: Structure for facilitating test to printed wiring board
Inventor: NOKIMURA HITOSHI
IPC: G01R31/28
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To easily specify a failure point of a printed wiring board without using a socket, etc., by making a voltage of an output terminal closer to a voltage of a second power source than a threshold voltage of a third boundary scan cell when a wiring normally connects a connection point between a first output terminal and a second resistor. SOLUTION: A boundary scan cell 46A outputs a control signal realizing a non-high impedance to a tristate buffer 44, and a boundary scan cell 46B outputs a test pattern. A third boundary scan cell 46C measures a voltage value from an output of the buffer 44 and judges that a wiring 40 is shortcircuited when the voltage does not agree with an expected value. After the wiring 40 is confirmed not to be shortcircuited and when the buffer 44 is turned to a high impedance, a voltage level of an output terminal of an LSI 36 becomes equal to a first power source voltage if the wiring 40 is opened, or at the side of a second power source voltage if the wiring is not opened. Even when the LSI 38 is designed to cope with a non-boundary scan, a shortcircuit/open test for the wiring 40 is enabled.

IPC: B66B1/28
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To certainly detect brake dragging against the number of passengers of an elevator anal torque fluctuation by its inertial moment. SOLUTION: Torque command values 4a-4d are computed from deflection of speed command values 2a, 2b and actual speed 3a, 3b, and a torque command average means 8 computes average values 8a-8d of the torque command values 4a-4d along from one time starting to stopping of a cage. An imbalanced torque detection means 9 detects an imbalanced torque command value 9a to hold a weight difference between cage side weight while a cage stops and balance weight weight. Imbalanced torque is calculated by subtracting the imbalanced torque command value 9a from the torque command average values 8a-8d by a brake dragging discrimination means 10, and when it becomes higher than a specified value, it is judged as brake dragging, and restarting of the cage is prevented.
