Inventor: KONISHI HIDEAKI
IPC: G01R31/28
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To obtain test patterns efficient in detecting faults by estimating the probability of occurrence of faults to be sampled in logic circuits according to the layout of the logic circuits, arranging faults in order of decreasing probability on the basis of the obtained probability of detected faults, and creating test patterns obtained by compressing patterns in which faults overlap. SOLUTION: A test pattern creating device 2 executes program for test patterns stored in advance in program memory 12 by a processing part 13 in response to instructions from an input device 17 and creates test patterns on the basis of the layout information of logic integrated circuits 3-1 to 3-n to be tested stored in advance in a layout information storage part 11. In fault information, a higher priority is assigned to a fault which easily occurs, and a fault with a higher priority is compressed into a pattern so that it can be priorly processed. A testing device 4 detects output patterns from the logic circuits 3-1 to 3-n and determines whether they are logically normal or not. In the case that they are not logically normal i.e., the logic circuits are faulty, later tests are canceled to indicate the presence of a fault.

Title: Impeller for centrifugal compressor
Inventor: FURUYA YASUSHI
IPC: F04D29/30
Filed: 1983-11-17
Abstract: PURPOSE:To improve the efficiency of diffuser by varying the output diameter of impeller and the output vane angle against the circumferential direction of a centrifugal compressor thereby improving distortion of speed from hab side to shroud side. CONSTITUTION:The locus of working fluid will be short at the shroud sides while long at the hab side H because of the shape of impeller 1 of centrifugal compressor thereby distortion of speed can be reduced by increasing the output diameter of impeller 1 toward the shroud S side. Alternatively, the output vane angle against the circumferential direction of impeller 1 is increased toward the shroud side to equalize the angular motion subjected to the working fluid or both methods can be combined. Since the speed of working fluid at the outlet of impeller 1 is uniformed, the speed is uniformed across the diffuser inlet resulting in improvement of diffuser efficiency.

Title: Humidifier
Inventor: HIRAYAMA KENICHI
IPC: F24F6/04
Filed: 1985-09-27
Abstract: PURPOSE:To prevent the spilling of water and wetting the floor and ceiling and the breakage in a porous sheet due to high pressure by opening always an open pipe connected to the joint opening of the pipe used for both drain outlet and open pipe connection opening in a hollow structure and leading the drain water to a drain pan even if a water control device is out of order and water supply can not be stopped. CONSTITUTION:An open pipe 9 connected to the opening 4 for both drain outlet and open pipe connection in a hollow structure 5 is supported on a hook 10 at the topmost position of its inverted U-shape, and the end of the pipe 9 is extended to a drain pan 11. During operation the water level H is maintained substantially at a fixed height by means of a float switch 8, and the water is filled neat up to the highest position 9a. When the water supply can not be stopped due to a trouble with an electromagnetic valve 7 or a float switch, the amount of water supply far exceeds the amount of humidifying, raising the water level H higher. If the water level rises even a little, the water is drained by overflowing the highest point of the open pipe. When the open pipe 9 is removed from the hook 10 and lowered lower than the ordinary water level H, water drainage can be easily effected and it is also easy to clean the inside of the hollow structure 5.

Title: Semiconductor device
Inventor: NAKADA SHINJI
IPC: H01L23/34
Filed: 1993-08-31
Abstract: PURPOSE:To prevent the disturbance of a cooling air flow around a semiconductor device by forming a package sealing a semiconductor element in a streamline shape. CONSTITUTION:The leads 13 of a semiconductor device 11 are smoothly continued from the package 12 of the device 11 in a streamline shape. Therefore, when cooling air A is sent from one side of the package 12 in its width direction, the air A flows along the upper surface 16 of one lead 13 in the circumference of a semiconductor element 11. Then the air A reaches the upper surface 15 of the package 12 and downward slope of the package 12 on the opposite side after passing the top of the package 12. The air A then flows along the upper surface of the other lead 13 towards a semiconductor element in the succeeding stage while the air A is maintained in the state of a laminar air flow. Namely, the cooling air A is sent to the succeeding stage after removing the heat of the package 12 while the air A is maintained in the state of a laminar air flow. Therefore, a desired cooling effect can be obtained, since the coming off of the air A from the package is suppressed and the cooling air A is prevented from becoming a turbulent flow.

Title: Controller for average shift time of output value
Inventor: TOUFUSA MASAYUKI
IPC: G05B17/02
Filed: 1985-09-30
Abstract: PURPOSE:To secure the coincidence between the average shift time of the output value and its set level in many time bands when the set level is given, by using an algorithm arithmetic means, a means to deliver the output command value equal to the output target value, etc. CONSTITUTION:An algorithm arithmetic unit 5 contains an output signal storage 7 and an algorithm arithmetic part 8. The storage 7 stores the output value (y) up to a present time point from a past time point. While the part 8 delivers the optimum output target value (x) to a subtractor 9 based on the input data. The subtractor 9 supplies the value (x) and the set value R given from a setter 2 for execution of subtraction and delivers the bias value (h) to an adder 10. The adder 10 adds the value (h) with the value R and delivers the output command value Z to a subtractor 11. The subtractor 11 obtained a deviation (e) and delivers it to a PI arithmetic unit 12. The unit 12 applies an input signal (f) to an equipment unit 13 so that the deviation (e) is equal to zero. Thus the value (y) is coincident with the value (x) and the average shift time of the output value is coincident with a set level in many time bands.

Abstract: PURPOSE:To make the level of a modulation signal continuous by correcting an output of an electronic volume changing the level of the modulation signal to a voltage controlled oscillator in multi-stage by an output being the result of low band filtering of a phase detection output. CONSTITUTION:An output frequency f0 of the voltage controlled oscillator 12 is frequency-divided by a variable frequency divider 13 into a prescribed frequency. Moreover, an output frequency fS of a temperature compensation type crystal oscillator 15 is frequency-divided by a fixed frequency divider 16. Both frequency division outputs are subjected to phase detection 14 and resistance filtering 17, resulting in obtaining a voltage VF eliminated with undesired noise, the voltage is fed back to the voltage controlled oscillator 12 and inputted to a voltage conversion circuit 18. The output of the electronic volume 11 changing the level of the modulation signal in multi-stage is corrected by the output of the voltage conversion circuit 18. Thus, the level of the modulation signal is made continuous, the modulation sensitivity is uniformized and a flat modulation characteristic is obtained over the entire band of a broad band channel.
