Patent JP-H09192552-A (JP)
Title: Sprayer
Inventor: YANAGIDA JUN
IPC: B05B11/00
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a small sizes and continuous sprayer which does not cause liquid drip and can stop spraying at once when spraying is stopped and usable in the interior of a house. SOLUTION: A liquid is sucked from a tank 3 by operating a trigger handle 4 and the liquid is temporarily collected in the inside of an accumulator 9. As the liquid introduced into the accumulator 9 increases, a wall face 12 moves while resisting against a spring member 13 and finally the liquid is pushed by the resilient force and sprayed through a nozzle 8. In the case of stopping the trigger handle 4, since a valve completely chokes a second liquid flowing pipe 7 by simultaneously pushing a button, liquid supply to the nozzle 8 is stopped. Moreover, following the movement of the valve, the inside of the accumulator 9 is communicated with a line 24 led to the tank and the pressure is lowered, so that the pressure applied to the nozzle 8 is shut. Consequently, spraying through the nozzle 8 is stopped and liquid drip is instantly prevented.

Title: Image forming device
Inventor: MASUYAMA HIROSHI
IPC: G03G21/00
Filed: 1994-03-01
Abstract: PURPOSE:To prevent unintentional erasure of important images on papers such as a document to be preserved and an original by providing a marking means which puts a mark indicating erasable or not erasable on image and an instructing means which gives instruction to put the mark by the use of the marking means. CONSTITUTION:In a digital copying machine 1, erasure inhibition mode is freely selected by the use of the instruction means. In the formation of an original and a document to be preserved, etc., when an image forming operation is performed after the erasure inhibition mode is specified by the use of a consol panel, a specific image mark which indicates erasure inhibition is put on a part of transfer paper 20 as mark showing erasable or not erasable on the image. On the other hand, in the image formation in which the erasure inhibition mode is not specified, an ordinary processing in which the erasure inhibition image is not marked is performed. Thus, because the original and document to be preserved, etc., are prevented from being carried to a toner removal processing after detection by a mark detecting means and they are immediately ejected, unintentional erasure of the important images can be prevented.

Title: Synchronizing method at demodulation of broad band signal
Inventor: MUTOO YOSHITAKA
IPC: H04L7/00
Filed: 1980-03-14
Abstract: PURPOSE:To reduce the time of re-drawing in, by measuring the absence time of signal and limiting the range of timing shift in search mode to the range of difference of maximum timing. CONSTITUTION:When synchronism is taken and the reception signal is present, the discriminated output of the level discrimination circuit 19 is fed to the shift control circuit 22 to turn off the output to the timing shift circuit 24. Further, if the input signal is absent, the time is measured at the time measuring counter 20 and the search width set signal proportional to the time is output from the code converter 21 and this output is input to the control circuit 22. The control circuit 22 produces the timing control pulse corresponding to the search width, controls the timing circuit 24 and shifts the drive clock. Thus, if the synchronizing circuit is operated in the search mode and the signal is again received, since the input of the circuit 19 is greater, the output to the timing shift circuit 24 is OFF and the mode can be transited to the tracking mode.

Title: Manufacture of semiconductor device
Inventor: YANO KEIKO
IPC: H01J37/302
Filed: 1989-02-10
Abstract: PURPOSE:To remarkably reduce the load of time spent for correction processing, and sharply realize the contour of a pattern by performing figure processing wherein only the size of a figure itself is considered and the size and the distance of an adjacent pattern are not required to be taken into account. CONSTITUTION:Design data of design figures (a)-(d) are firstly transformed into electron beam exposure data, and then a large figure (b) requiring contour processing is selected. The figure (b) requiring the contour processing is divided into contour patterns 1-4 of (b) and an internal pattern 5 of (b). Further, the internal pattern 5 of (b) is transformed into an internal reduced pattern 51 of (b). then electron beam exposure density is assigned to each figure. The part between the contour patterns 1-4 of (b) and the internal reduced pattern 51 if (b) is a kind of buffer zone. By providing said zone, the figure itself is prevented from stretching more largely than the design value, and the adverse influence on the adjacent pattern is restricted in a small range. Thereby, the contour of a large figure can be drawn sharply, and the time load, of a computer, necessary for pattern connection processing can be decreased.

Filed: 1995-01-30
Abstract: PURPOSE: To certainly fasten a synthetic-resin-made flat band with a simple operation by a method wherein a frame like a painting frame is made up of a pair of opposite thick side members and a pair of opposite thin side members and a slide bar is slidably provided via bridges that are raised from the thin side members toward the surface side. CONSTITUTION: A frame 1 of a stopper S is made up of a pair of thick side members 2a and 2b and a pair of thin side members 3a and 3b and clamp members 4a and 4b are provided on the thick side member 2a. A slide bar 7 is mounted on the thin side members 3a and 3b via bridges 6a and 6b so that it can slide toward the thick side members 2b. When the stopper S is used, the free end of a band is passed between the thick side member 2a and the slide bar 7 and pulled toward the thick side member 2b to make the slide bar 7 slide, so that the bridges 6a and 6b fall down toward the thick side member 2b. Thereby, the slide bar 7 is brought in press-contact with the thick side member 2b, thus the band is fastened.

Title: Picture transmitting method
Inventor: TAKAYAMA MAKOTO
IPC: H04N19/00
Filed: 1987-02-14
Abstract: PURPOSE:To shorten the retransmission time of an error block by transmitting it while the size of the block of a picture is changed according to the error rate of a transmission line. CONSTITUTION:A transmitter side transmits a test data before the transmission of a data, and receives the test data, which has made the round trip of one time through the line, and measures the number of the errors, and determines the data length of one block to be transmitted according to the number of the errors. The size of the block of a BLOCK 1 is larger. Further, the block numbers and the check codes of the same number of bits are attached to the BLOCKs 1 and 2. When the error rate is low, the proportions of the data of the block number or the check code is less, compared with that of the picture data. Because the number to be retransmitted of the BLOCK 1 is less, the data to be actually transmitted comes less, and the transmission time comes shorter. When the error rate is high, the data to be actually transmitted of the BLOCK 2 comes less, and its transmission time comes shorter.

Title: Terminal equipment in on-line system
Inventor: HATA KIMITOSHI
IPC: G06F1/14
Filed: 1988-02-17
Abstract: PURPOSE:To prevent waste of synchronizing operation of a terminal equipment by setting a count of a timer to a predetermined correction value in place of resetting an internal timer when the terminal equipment receives synchronizing correction signal while the internal timer elapses a prescribed count start point of time and counts a predetermined permissible value. CONSTITUTION:The synchronizing correction signal is sent from an electronic exchange 1 for minute and a telephone set control section 3 receives the synchronizing correction signal, then the synchronization correction is applied. In such a case, when the telephone set control section 3 receives the synchronizing correction signal till 0.04sec elapses from the count start point of time of the internal timer, the internal timer is not reset and the count-down from correction value 2.99 is started. Thus, it is rare to repeat the synchronizing operation twice in a short time at the count-down start point of time. Moreover, the synchronizing correction signal sent from the electronic exchange 1 is set to other terminal equipment. Thus, the electronic exchange 1, the telephone set control section 3 and other terminal equipment count mutually the identical time and the synchronizing operation of the electronic exchange system is maintained.
