IPC: G01T1/00
Filed: 1992-03-09
Abstract: PURPOSE:To enable the detector to make accurate measurement without requiring any high time resolution by providing a delaying fiber between a pair of radiation detecting sections so as to make the time difference between the arrival time of emitted light at photodetectors larger. CONSTITUTION:Photodetectors 2A and 2B, respectively composed of photoelectric multipliers, etc., are connected to both ends of a scintillation fiber containing a pair of radiation detecting sections 1A and 1B and a light delaying section 3 of, for example, about 20-50cm in length between the sections 1A and 1B. When scintillation emission occurs in the section 1A due to the incidence of radiation, the emitted light is detected by means of both detectors 2A and 2B, but the photodetector 2A detects the light emitted from the section 1A earlier than the photodetector 2B. When scintillation emission occurs in the section 1B, the photodetector 1B detects the emitted light earlier than the photodetector 1A. Therefore, when the time difference is found by means of a time difference measuring instrument 4, the light emitting section, whether the section 1A or 1B, can be discriminated.

Title: Debugging mechanism for information processor
Inventor: MORIOKA ATSUSHI
IPC: G06F11/28
Filed: 1990-03-02
Abstract: PURPOSE:To discontinue the execution of a microprogram in a designated address in the specific conditions only in a debugging state and to attain the collection of data in such conditions by discontinuing the debugging operation of the microprogram in the relevant address with the set-up of the prescribed conditions and an address. CONSTITUTION:A register 7 holds the address of a microinstruction during execution and this address is always compared with the value of a stop address setting register 6 via an address comparison means 8 during the execution of a microprogram. When the coincidence is obtained from this comparison, the means 8 outputs an address coincidence signal to a NAND gate 9. The output of the gate 9 goes to '0' as long as the register coincidence signal and the address coincidence signal go to '1' when an enable signal 11 is equal to '1'. Thus a processor clock 12 is gated by an AND gate 10 and not supplied to a processor 13. Consequently, the execution of the microprogram is discontinued. Thus, it is possible to discontinue the execution of the microprogram in the specific conditions only and to collect the data in such conditions.

Abstract: PURPOSE: To secure the transfer of thread by one procedure by composing thread  transfer mechanism with a thread catch guide having an inclined guide, which  makes reciprocation along a fixed guide, and a mobile guide moving interlocked  with the above.  
     CONSTITUTION: When a thread is transfered from a bobbin to a waste spool, a thread catch guide 17 make horizontal reciprocation between the stand-by position shown by the double-dotted chain line at the right and the position specified by a limit switch 29, during which a guide plate 44 is situated in the lower position following a pass as 1→2→3→2→1 and stops at the stand-by position upon catching the thread at a pawl in the thread catch guide 17. When, on the other hand, the thread is transferred from the waste spool to the bobbin, the guide plate 44 is situated at the upper position and therefore the arm 19, which is to fix the thread catch guide 17, moves along the guide plate 44 following a pass as 1→2→4→5→4→2→1. Thus transfer of thread can be carried out securely by a single operation.

IPC: B29C51/12
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a technique capable of keeping a sheet material laminated to a base material in an almost constant thickness. SOLUTION: In a base material/sheet integral molding method for heating and softening a sheet material 4 to laminate the same to base materials 2, 3 under vacuum, the sheet material 4 is arranged in a mold 10 and, thereafter, slits 4a, 4b are formed at the position corresponding to a tension induced part in predetermined length at a point of time when molding tension is generated in the sheet material 4 to perform integral molding. Therefore, by largely opening the long slit to slacken large tension and opening the short slit small to slacken small tension, even if tensions different in magnitude are applied to the sheet material, the tensions can be slackened to almost the same magnitude.
