Title: Positional slippage correcting device of electronic component
Inventor: NAKANISHI TOMOAKI
IPC: H01L21/52
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To provide a positional slippage correcting device for an electronic component, capable of avoiding the reslippage of the electronic component after finishing the positional slippage correction by a vacuum pressure applied on a gap between the under side near the interior angle part of a positional slippage correcting pawl and the stage upper side. SOLUTION: Suction holes 28 are made on the upper side of a stage 22 of a positional slippage correctin device 21. The suction holes 28 are formed in a wide area B and a slender area C on an electronic part A. nNext, a slit hole 24 is made in an interior angle part of a positional slippage correcting pawl 3. Then, the interior angle part of the correcting pawl 23 is pressed gainst an angle part of the electronic component A so as to correct the positional slippage. At this time, the slender area C in a state which faces opposite to the slit hole 24 is exposed.  Accordingly in this a state, no vacuum pressure is generated on the gap between the under side of the interior angle part and the upper side of the stage 22, so that even of the positional slippage correcting pawl 23 is restored to the original position after finishing the positional slippage correction, the electronic component will not be positionally slipped again, since the electronic component A will not be attracted by the vacuum pressure.

IPC: E03B5/00
Filed: 1993-04-20
Abstract: PURPOSE:To check the starting frequency of a conveying pump to the irreducible minimum of necessity as well as to cut operating power expenditure. CONSTITUTION:Since a flow rate is decreased by a drop of water consumption at the downstream side of a conveying pipe 2, a relief valve 6 is opened and water is discharged out of a small flow rate discharge pipe 7 at a point of time when pressure detected by a pressure detecting means 4 is shifted to a level equivalent to the shutdown point of a conveying pump 1. With this state continued as long as the specified time, operation of the pump 1 comes to a stop.

Title: Detecting and processing system for circuit trouble
Inventor: TSUBOI YOUJI
IPC: H04M3/22
Filed: 1982-06-01
Abstract: PURPOSE:To detect trouble occurring to a toll board connection circuit on an SR system, by calculating an incomplete call rate from the counted values of the frequency of connection requesting from a switchboard to a toll board and the number of aborted calls, and then comparing it with a predetermined threshold value. CONSTITUTION:A subscriber telephone 1 is connected to the toll board 5 by a switchboard 2 through a circuit 4. A controller 6 is provided with counters 7 (CNTA) for the frequency of connection requesting and counters (CNTB) 8 for the number of aborted calls corresponding to circuits; when the switchboard calls the toll board through one circuit, the counter 7 corresponding to the circuit counts the frequency and the counter 8 also counts the frequency of incomplete connection due to abandonment on the way. The incompletion rate (CNTB/CNTA) within a time set by a timer 9 is calculated and compared with a threshold value set in a threshold value register 12 by a comparison part 13, and when the incompletion rate is large, it is judged that circuit trouble occurs.

Filed: 1981-06-22
Abstract: PURPOSE:To attain economic, safe and reliable operation of a pump, by detecting malfunctioning of a water level detector at an early stage by providing a timing control circuit adapted for opening a water level depressor intake valve for a predetermined while in a water level controlling system including a water level depressor. CONSTITUTION:When a main control switch is turned to ''operation'' side in starting operation of a pump, a pump operating relay is energized on condition that conditions for starting operation of the pump are satisfied. Resultantly, an air intake valve 19 is opened and compressed air in an air tank 13 is supplied to a runner chamber 8 via an air supply pipe 17, so that the water level in the runner chamber 8 is depressd to the position of a detector 11 of a water level detector 9. When the water level is lowered to a predetermined position, the electric circuit of the detector 11 is opened. This causes closing of the intake valve 19, so that supply of compressed air to the runner chamber 8 is stopped. Therefore, the air intake valve 19 is opened only for a predetermined while during water level depressing operation required before starting pumping operation.
