Title: Method and device for testing resisting pressure of steel tube
Inventor: FUJITA TAKESHI
IPC: G01N3/12
Filed: 1978-09-05
Abstract: PURPOSE: To make it possible to detect accurately and continuously movement mobility of the positions at tube ends of a steel tube, even if very slight, by arranging a position detection plate in contact with flanks at both ends of the steel tube to be tested.  
     CONSTITUTION: Detection plates 2 and 3 are provided at fixed positions of head stock 11 and tail stock 10 through operation cylinders 8 and 9. When high pressure water P 1  is supplied into steel tube 1, head stock 1 starts moving backward, widening gap 21 between detection plate 2 and tail stock 10 and gap 22 between detection plate 3 and head stock 11. This mobility is detected automatically by position detectors 13 and 12 linked to detection plates 2 and 3 and pressure P 2  applied to main cylinder 16 is controlled by servo relief valve 18. Namely, gaps 21 and 22 are decreased when too large or increased when too small by the signal of valve 18.

Title: Announcement broadcast system
Inventor: SUGITA MASATOSHI
IPC: H04H20/59
Filed: 1987-05-01
Abstract: PURPOSE:To allow a liaison person oneself to switch a usual broadcast into an emergency broadcast so as to attain emergency communication by operating a start switch of a 1st transmitter on emergency or the like to interrupt a broadcast signal from a 2nd transmitter, thereby modulating a broadcast signal and a tone signal from the 1st modulator and sending the result to a common reception line. CONSTITUTION:When an announcement broadcast is broadcast from an information center 8 in the event of an emergency such as a crime or a fire, a start switch 23 of the 1st transmitter 10 is depressed in the information center 8. Thus, a tone signal is outputted and mixed with a signal of an announcement broadcast by a mixer circuit. A signal being the result of demodulating the above signal is fed to a voice input terminal 18Ac or 18Bc in 2nd modulators 18A, 18B and a tone signal is detected by a signal detector. Thus, a signal representing the announcement broadcast and the tone signal are fed to an FM modulation circuit and they are modulated and outputted from a high frequency output terminal 18Ab. Thus, even when any voice signal is listened to at a terminal equipment side, the broadcast is automatically switched to the announcement broadcast and it is broadcast further with an increased sound volume automatically.

Title: Image display device
Inventor: SAWA NOBUYOSHI
IPC: G06K9/32
Filed: 1993-05-12
Abstract: PURPOSE:To provide an image display device which is capable of performing a rotation display of a screen to be displayed by a display device by an arithmetic processing of only integer addition and subtraction. CONSTITUTION:A display device 3 displays the image signal that an input image storage part 11 stores on a display screen at first. An indicating device 4 inputs an arbitrary location in the display screen and recognizes the angle of inclination of the display screen. A moving amount storage part 16 stores the moving amount for each picture element of the display screen to rotate the image of the display screen for the only angle according to the angle of inclination. This moving amount is calculated by addition and subtraction. A correction image storage part 15 stores the image signal as the coordinate moved for the only moving amount, as for the coordinate of each picture element that the input image storage part 11 stores. The coordinate moving for each picture element at this point is also performed by addition and subtraction. The display device 3 displays the image signal that the correction image storage part 15 stores or the image correcting the inclination. Therefore, the processing speed for the rotation of a screen can be remarkably improved.

Title: Manufacture of deodorant including indicator
Inventor: OGURA NOBUO
IPC: A61L9/01
Filed: 1993-03-31
Abstract: PURPOSE:To judge the performance of deodorant to odor gas with the naked eye easily. CONSTITUTION:It is difficult to judge with the naked eye the performance of a deodorant prepared by additionally mixing sawdust with a liquid composed of nonvolatile acid or paraoxybenzoate and acetate. With the addition of indicator such as methyl red or neutral red to the deodorant, the existence of deodorizing performance thereof can be judged easily with the naked eye from the change in color. In this case, it is desirable to use such sawdust decolored as allowing a user to know the decolored area cleary. Paper can be usable in the same manner as sawdust. Further if cinnamon is added the fragrance of cinnamon alkehide is kept to generate until the deodorizing performance disappears. The deodorant is filled in a film bag having pores and applicable widely as the deodorant of a deodorizing device or air cleaner.
