Title: Slant incidence type x-ray image apparatus
IPC: A61B6/03
Filed: 1992-03-31
Abstract: PURPOSE:To achieve higher resolutions of concentration and space by inclining a detection surface of a semiconductor detector by a specified angle to a plane orthogonal to the direction of traveling of a fan beam X-ray transmitted through an object. CONSTITUTION:The dimension in the direction of scanning of a detection surface 1a of a detector is represented by P. Cases herein considered are where the detection surface la is arranged vertically to an X-ray beam B and where the detector 1 is so arranged that the detectionsurface 1a thereof is inclined by thetacentered on an axis alpha along the direction of the X-ray fan beam B expands. When an inclination is given by, an X-ray incident width in the direction of scanning the detection surface 1a by X rays decreases to P*costheta to improve the space resolutions in the direction of the scanning. When the detection surface 1a is inclined by theta with irradiation X ray dose being adjusted so that the maximum incident rate of the X rays into the detector 1 reaches the allowable upper limit I of counting loss, the maximum counting rate with the detector 1 decreases to I*costheta. The limit of the concentration resolutions attributed to dead time is eased to improve the concentration resolutions, accordingly.

Title: Production of 2,6-diethylnaphthalene
Inventor: TAKEUCHI HARUKI
IPC: C07B61/00
Filed: 1992-02-26
Abstract: PURPOSE:To efficiently and inexpensively produce 2,6-diethylnaphthalene useful as a raw material for 2,6-naphthalenedicarboxylic acid, etc. CONSTITUTION:This method for producing 2,6-diethylnaphthalene comprises a reaction process for reacting naphthalene and/or ethylnaphthalenes with a polyethylbenzene in the presence of an acid catalyst and a separating process including precise distillation and absorptive separation for separating 2,6- diethylnaphthalene from reactional products produced in the reaction process. The objective 2,6-diethylnaphthalene is produced by circulatingly returning at least part of residual naphthalene or ethylnaphthalenes after separating 2,6-diethylnaphthalene obtained in the separation process to the reaction process. Since polyethylbenzene produced as a by-product in an ethylbenzene producing process is used as an ethylating agent raw material, not only its treatment is saved but also ethylbenzene is produced as a by-product, thus the polyethylbenzene can be recovered as a usable product. Thereby, industrial signification of this method is further enhanced.

Title: Long-work feed-distance detector
Inventor: FUKUSHIMA YOSHIAKI
IPC: G01B7/04
Filed: 1978-06-22
Abstract: PURPOSE: To prevent the production of defectives by detecting the feed distance of long work and by stopping the operation of a cutting machine when feed distance is short.  
     CONSTITUTION: When a work feeder 1 operates to feed long work W to a cutting machine, the transfer body 16 holding said long work W with a clamp 25 advances together with said work W. When said work W is fed over a prescribed distance, a detector 40 operates to give operation continuation instruction to said cutting machine. If said work W is not fed over a prescribed distance due to the slip thereof, said transfer body 16 is short of transfer distance. Consequently, therefore, the operation of said cutting machine is stopped so that the production of defectives can be prevented.

IPC: H04N5/76
Filed: 1990-03-26
Abstract: PURPOSE:To simplify the timer reservation operation by delaying a video recording start time to be set till a pilot signal in a television signal is detected and terminating the video recording when the pilot signal is not detected for a prescribed time after the start of video recording. CONSTITUTION:A voice/detection circuit 15 detects the presence of a bilingual broadcast pilot signal or a stereo broadcast pilot signal in an audio signal from an audio intermediate frequency SIF circuit 14 and gives a detection signal P1 or P2 to a discrimination circuit 7 of a microcomputer 2 when the pilot signal is detected. Upon the receipt of a video recording signal R from a reservation execution circuit 4, the circuit 7 recognizes the signal P1 or P2 to start the reservation video recording. When no signal P1 or P2 is supplied, the circuit 7 controls a mechanism control circuit 18 via a system controller 16 to halt tape drive tentatively and to stop it after lapse of a prescribed time. Thus, the setting of the end time is not required and the reservation is simplified.
