Title: Method and device for inspecting defective article
Inventor: OKABE MASAHARU
IPC: G01B11/30
Filed: 1995-03-31
Abstract: PURPOSE: To prevent noise occurring at start and end points of inspection, by so setting threshold value that the times when sensor input signal change significantly are starting and end points of inspection so as to generate inspection area signal, and fast-switching between the differential signal between that and input signal and constant value signal, for outputting. CONSTITUTION: The light of a laser source 6 is scanned with a polygon mirror 7, and by irradiating the inspection area of a to-be-inspected object 8 wider, the reflected light is photodetected with a sensor 1. A threshold value setting means 21 sets a threshold value to be intermediate level of photodetected signal inside and outside the t0-be- inspected area, and the photodetected signal is dialyzed by a binalizing means 22, and a logic circuit 23 generates to-be-inspected area signal, and it is outputted to a sample hold circuit 32 through a single shot circuit 31. The circuit 32 holds and outputs the photodetected signal at inspection start point. A difference calculation circuit 33 obtains output difference between the photodetected signal and the circuit 32, and a switch circuit 34, based on the area signal, switches between the output of circuit 33 and the earth.  Thus, step of sensor 1 output between before and after the to-be-inspected area is removed, so that inspection to the end part of area becomes possible.

Title: Trigger device for surgical instrument
Inventor: WITT DAVID A
IPC: A61B17/072
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To mutually independently rotate a first trigger and a second trigger by arresting the rotation of the second trigger until the first trigger moves a shooting conducting assembly to a remote position. SOLUTION: A shooting conducting assembly has a shooting bar 43 extended from a frame to the surgical fixing assembly of an end effector, the shooting bar 43 is arranged between right and left blocking plates 32, 33. When the shooting bar 43 continues to move forward, the tip of a coach shooting trigger link 51 makes contact with the side connecting surface 49 in the proximal end section of the shooting bar 43. Consequently, a shooting trigger 31 which is a second trigger moves the shooting bar 43 to a remote position after perfectly fastening the body tissue, and arrests the rotation of the shooting trigger 31 until the shooting trigger link 51 can be engaged with the terminal engaging surface of the shooting bar 43. Thus, a blocking trigger 30 which is a first trigger and the shooting trigger 31 can be mutually independently rotated.

Title: Ink-jet head
Inventor: TAKADA MASAYUKI
IPC: B41J2/045
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To restrict the generation of air bubbles in a feed path in a simple constitution and prevent a jetting failure, by forming at an inner wall face continuous with the feed path at an intake path where an ink solution from an ink feed source of an ink-jet head enters, an inclined face gradually increasing a sectional area of the path towards the feed path. SOLUTION: An ink solution from an ink cartridge 25 enters an intake path 16 through an ink intake opening 19 of a manifold 15 into a feed path 14. The ink solution in the feed path 14 is supplied into each jet channel 12 of an actuator 13, and jetted as liquid drops from a nozzle of a nozzle plate when a capacity of the jet channel 12 changing because of a deformation of the actuator 13 is reduced. In this case, an inclined face 18 is formed at an inner wall face continuous with the feed path 14 at the intake path 16, which gradually increases a sectional area of the path. Therefore, the ink solution entering the intake path 16 softly flows to the feed path 14 along the inclined face 18, thereby restricting the generation of air bubbles.

Title: Controller for synchronous motor
Inventor: SHIMIZU MASAO
IPC: H02P27/06
Filed: 1991-02-21
Abstract: PURPOSE:To detect the rotating condition of a rotor exactly without using an angle sensor or the like by detecting a change in the load of a synchronous motor as a change for armature voltage drop. CONSTITUTION:Terminal voltage V becomes reference voltage V1 by multiplying a constant K2. Armature current Ia becomes comparison voltage V2 by multiplying a constant K3. Comparison voltage V2 corresponds to armature voltage drop. A difference between the voltage V1 and V2 is inputted in a VF converter 6, where angular frequency omega0 proportional to the voltage difference is set, and is outputted to an inverter 7. When the load of a synchronous motor 8 is small, armature voltage drop is small. As a result, a difference between the outputted voltage and the armature voltage drop becomes large, and large angular frequency corresponding to the angular velocity of a rotor which rotates at a relatively high speed is set. When the load of the synchronous motor 8 increases, a difference between the outputted voltage and the armature voltage drop becomes small, and small angular frequency corresponding to rotor angular velocity which is decreased by the load is set.
