Title: Analog-digital conversion duplexing circuit
Inventor: NARIHARA KOSHU
IPC: H03M1/10
Filed: 1987-10-14
Abstract: PURPOSE:To avoid a double trouble and to improve reliability by duplexing an analog-digital converting circuit, parallely processing an analog input point respectively by 1/2 at a normal time and processing all analog input points with a normal circuit when any one of the circuits is abnormal. CONSTITUTION:The analog input point is parallely processed at a high speed respectively by 1/2 at the normal time with utilizing duplexed analog-digital converting circuits 4 and 14. Reference input signals 6 and 16 are inputted to the idle channel of analog switches 5 and 15 and data, which are after the A-D conversion is ended, of the reference input signals 6 and 16 are cyclicly supervised. When the data are out of a reference range, the said A-D converting circuits 4 and 14 are judged to be abnormal. When either the A-D converting circuits 4 or 14 is judged to be abnormal, the remaining normal circuit is used. Thus, the duplexed analog-digital converter is effectively operated and the high speed is maintained by parallel operation at the normal time. Then, when either of the circuits is abnormal, the normal circuit executes the operation instead of the abnormal circuit and the double trouble can be avoided.

Title: Constant slew rate amplifier
Inventor: YOUNG WILLIAM RONALD
IPC: H03K19/003
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To provide the amplifier with a constant slew rate to drive a load such as a digital communication line in matching with data transmission where an input signal has a comparatively low voltage. SOLUTION: A voltage level shift bias supply circuit 10 produces a voltage going to a positive level or a negative level corresponding to a rapid change in an input signal and gives the voltage to next stage positive/negative ramp control section 20/30. The positive and negative ramp control section 20/30 generates a well-regulated and monotonically changing voltage. The output of the section 20/30 is amplified respectively by a gain stage 40/50 and the amplified signal is given to an output line 12. In the output line 12, a ramp voltage generated from the pre-stage reaches a prescribed threshold level at a desired slew rate.  When the ramp voltage reaches the threshold level, a switching circuit connecting with each gain stage 40/50 is triggered to directly boost a voltage of the output line 12 to a positive supply voltage or to directly lower a voltage of the output line 12 to a negative supply voltage in response to a shift of a level of an input signal INPUT.

Abstract: PROBLEM TO BE SOLVED: To prevent a sparking during a coating operation, coating defects due to an abnormal approach of a coater to an object to be coated and impact of a coater on a object to e coated, from being caused by surely detecting a abnormal approach of a coater to an object to be coated. SOLUTION: In the coating process using this equipment, first, the shape of an object to be coated W and the position of a marker M are detected based on image signals from an image pickup device 6 for photographing the object W and a coater 3 that is provided with the marker M discriminable from the background in an photographic image to be produced by the image pickup device 6, and then, based on the shape of the object W, an abnormal approach region A is set. When the position of the detected maker M enters into the abnormal approach region A, an abnormal approach signal is outputted and therefore, abnormal approach of the coater 3 to the object W can surely be detected depending on whether the abnormal approach signal is outputted or not.  Accordingly, sparking is prevented from being caused by cutting off a high voltage applied to the coater 3 or the object W, based on the abnormal approach signal and also, coating defects due to the abnormal approach of the coater 3 are prevented from being caused by interrupting the spraying of a coating material based on the abnormal approach signal and further, impact of the coater 3 on the object W is prevented from being caused by stopping movement of the coater 3 based on the abnormal approach signal.

Title: Inspection jig for elevator landing device
Inventor: KUBO HITOSHI
IPC: B66B1/36
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To facilitate abnormality determination based on the fact that a scale is raised when a positional relationship between an inductor and a plate is other than a managed value during car lowering by combining scales for measuring the gap dimension of each direction between the inductor and the plate and attaching these freely rotatably to the inductor. SOLUTION: For inspecting whether a gap dimension between the inductor 3 and the plate 4 of a landing device is within a proper range or not, first the center of an inspection jig is decided by a reference member 12 and then a base 11 is adsorbed on an attaching member 2. Then, vertical scales 14 and 15 and a horizontal scale 17 are fixed according the managed values of the inductor 3 and the plate 4 and each gap dimension is measured by the scales 14, 15 and 17. Then, an elevator is run for inspection, but at this time if the measured gap dimension does not match the managed value, the plate 4 comes into contact to raise the scale assembly. Thus, the failure of a gap dimension between the inductor 3 and the plate 4 is easily determined and set to the managed value by using scales 14a, 15a and 17a on the spot.
