Title: Prevention for clogging of sprue
Inventor: SHIMAZAKI HAJIME
IPC: B22D18/04
Filed: 1981-09-22
Abstract: PURPOSE:To prevent clogging of a sprue in low pressure casting by pressurizing the molten metal in a heat insulating furnace and holding the molten metal surface in a stalk always constant in the upper position of the stalk. CONSTITUTION:Molten Al 2 is charged under low pressure from a heat insulating furnace 1 into a sprue 8 of a bottom part 7 through a stalk 5 and a sub- riser 6 under low pressure, and is packed into product parts. If in this time the stalk 5 and the sub-riser 6 cool quickly, the molten metal returning to the inside of the furnace 1 through the sprue 8 then through the sub-riser 6 and the stalk 5 upon ending of the packing in the product parts solidifies and clogs the sprue. However, air is forced through a pressurizing pipe 4 into the furnace 1 to keep the metal 2 pressurized; therefore the molten metal level in the stalk 5 is maintained always constant in the upper position of the stalk 5. Thus the cooling of the stalk 5, the sub-riser 6 and the sprue 8 is obviated by the temp. of the metal 2, whereby the clogging of the sprue is prevented.

Title: Power continuity control circuit of output channel at control time of output of current supply treatment device for many affected parts
Inventor: OKAMOTO TSUNEKI
IPC: A61N1/32
Filed: 1987-06-15
Abstract: PURPOSE:To easily set a suitable current supply level and to certainly prevent the excessive supply of a current, by automatically operating the exclusive and alternative interlock between output channels at the time of control of initial output. CONSTITUTION:At the time of the control of initial output, the exclusive and alternative prescription of an output channel is automatically performed. Further, a current supply treatment device is prescribed by a logical circuit. So far as no control current supply start signal is imparted to the output channel, an operation start signal is ineffective. Since both of the prescription based on an exclusive and alternative interlock and an initial condition become the obstruction at the time of treatment current supply, a prescription release signal is separately imparted at the point of time when initial output control is finished to release the prescription. When a current supply stopping signal is applied at the time of operating current supply, all of channels stop output. At the same time, the exclusive and alternative interlock between the output channels and the initial condition relating to the continuity of a switch element are restored.

IPC: G03G15/01
Filed: 1982-08-30
Abstract: PURPOSE:To enable the image formation from the home position of a drum, by comparing the timing for arriving of a rotating drum at a prescribed angle position when a beam approaches the prescribed distance at the end of a photosensitive drum and suspending the scanning for the 1st line if there is too much space. CONSTITUTION:The latent image on a photosensitive drum 8 is developed with toners of three primary colors YMC, and is transferred three times superposedly on the same sheet, whereby a color copy is obtd. When the home position 11 of the drum is detected within the prescribed time after arrival of the beam 7 of a laser 5 deflected by a mirror 6 at a prescribed position 10, the beam is modulated by an image signal from the point apart by l from the position 10 for the beginning end of the beam, and the formation of the image is started. When the timings for both detection are apart too much, the formation of the image is stopped in the scanning of that time and the scanning is accomplished from the next second line. Since the pitch of the lines is small, there is no influence on the image quality even if one line is dropped out.

Abstract: PURPOSE:To eliminate unevenness in tension of the warp by a method wherein a plurality of circular double hollow weave parts are formed inside a joined singlet texture zone, and width in the direction of the warp in relation to the whole warp of the bonded singlet texture zone per one hollow weave part is set to a value 1.2 or less times as large as the minimum value of the width. CONSTITUTION:A double hollow weave part is formed with a surface fabric 2 and a back fabric 3, and a joined singlet zone 4 is formed outside the double hollow weave part. In one hollow weave part, the shape of a zone 4 is decided such that lengths in the direction of the warp in the zone 4 are made substantially equal to each other. Namely, the shape of the zone 4 is decided such that a sum of length 5a+5b, a sum of length 6a+6b, and a sum of length 7a+7b, and substantially the lengths of the warp are made equal to each other. Width in the direction of the warp in relation to all warp in the zone 4 is set to a value 1.2 or less as large ss the minimum value of the width. Thus, unevenness in tension of the warp is suppressed to a value within a range in which it is not inconvinent.

Abstract: PURPOSE:To realize natural input in the flow of a sentence without hiding a character which is previously recognized and displayed by providing two input frames and sequentially shifting the character input frames in a character input direction whenever the character is inputted. CONSTITUTION:An input part consists of LCD executing prescribed display and a tablet which detects an input position by a pen and outputs coordinate data corresponding to the input position. A display frame 7a is provided for the character input position and an input frame 7b is provided contiguously to the display frame 7a. Then, the same display frame 8a and input frame 8b are provided in the contiguous character input positions in the character input direction. When the character is written in one input frame, handwriting is displayed in the display frame displayed in the input frame. When input terminates, the character is recognized and displayed, and the input frame and the display frame, which correspond to the inputted character, shift to the character input direction. Since the input frame into which the character is hand-written is shifted and displayed near the recognized character in the input direction at every input, the hand-written character can naturally be inputted.
