Title: Reader for radiation image information
Inventor: MATSUDA TERUMI
IPC: G01T1/29
Filed: 1984-03-09
Abstract: PURPOSE:To obtain an excellent reproduced image by providing an excited light reflection preventing film which prevents the reflection of excited light on the incidence end surface of a light converging body and thus preventing excited light which is reflected by a sheet from striking the sheet again. CONSTITUTION:A storage type phosphorescent material sheet 3 is irradiated with scanning laser light 1b to cause accelerated phosphorescence at the irradiated position on the sheet 3 to intensity corresponding to image information, and its emitted light is guided from the incidence end surface 4a of the light converging body 4 into the light converging body 4 and converted by a photomultiplier tube 5 to an electric signal to read an image. A vapor-deposited film of a material which has a smaller refractive index than the material of the light converging material 4 is formed as excited light reflection preventing film 13 on the incidence end surface 4a, so the excited light which is reflected by the irradiated part is never incident on the sheet again. Consequently, the accelerated phosphorescence obtained through the light converging body 4 corresponds accurately to the amount of stored and recorded information of the accelerated phosphorescence.

Filed: 1989-02-27
Abstract: PURPOSE:To simplify a test sequence by forming a test sequence passing all states finally and consisting of several short test sequences started from the initial state and ended in the initial state. CONSTITUTION:The shortest route of state transition among respective states S1 to S4 in an order circuit is found out, a test sequence is formed based upon the shortest route of state transition between the initial state S1 and the farmost state S4 most far from the initial state S1, the farmost state from the initial state S1 out of unpassed states not passed by the shortest route is set up as the farmost state to repeatedly form test sequences, and when there is no unpassed state, the formation of the test sequences is ended. Thereby, the test sequence surely passing all the states can be formed by a short length. Consequently, a short test sequence appropriate for a reference test of capable checking the possibility of transition to respective states and allowed to be easily used can be obtained.

Title: Failure point orientation device
Inventor: TAKEDA AKIO
IPC: H02H3/40
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To output an oriented value after correcting the difference between a line length settling caused by difference between a transmission line dip or topographical altitude and an actual length. SOLUTION: This device is equipped with an orientation operation part 1 for calculating the distance to a trouble point by using voltage and current data converted into digital quantities and for outputting an oriented value, and a correction calculation part 2 for executing a correction calculation of the difference between a settled electric line length and an actual plane transmission line length relative to the oriented value outputted from the orientation operation part 1. Hereby, as for line length settling, conversion from a plane distance to an actual length is executed before an orientation operation, or as for the obtained oriented value, the actual length is reconsidered to a plane distance to execute the line length settling of the transmission line by treating as a plane length.  Therefore, in spite of the difference of treating relative to the line length, that the orientation operation is executed by an actual length, an orientation error caused thereby can be improved, and a trouble point orientation device having higher accuracy can be provided.

Abstract: PURPOSE: To transport solid/liquid mixture such as slurry with a tube roller pump smoothly by making a tube roller pump in a special construction and by restricting the arrangement of conduits communicating to the pump's incoming and outgoing ports.  
     CONSTITUTION: As a tube 7 is fixed at such a pressure as not squeezed by the fixation part 8 and a fixing piece 9, the tube 7 is given such a frictional contact as not dislocated during pump operation. The tube 7 is further assisted for not having dislocation by a roller 6 which is designed as rotating freely through appropriate fit of the bearing. The solid portion 11 will sink while the pump is at standstill, or while it is operating so long as the flow speed is low, but deposit of the solid 11 is restricted to the area 12 behind the roller 6 because of roller 6 being provided in two pieces. The solid 11 depositing at the other area, the horizontal part, is distributed evenly to assure to accumulation there, and the roller 6 will not be hindered from proceeding at the starting time of pump etc. The arrangement of conduits 1, 5 will further hinder the solid 11 from staying at the inlet 2 and outlet 4.
