Filed: 1986-05-26
Abstract: PURPOSE:To prevent separation due to pressure difference between inside and outside a combustion chamber, by furnishing a nozzle closure with a draft hole, which puts inside and outside the combustion chamber in communication, and with a filter. CONSTITUTION:A nozzle closure 4 formed from elastic substance such as rubber has a circular block part 4a and a righ-shaped mounting part 4b.

IPC: H02K44/02
Filed: 1990-05-09
Abstract: PURPOSE:To carry magnetic powder without using a rotating mechanism by laying plural conductors in parallel along a specified path in the width direction of the path, coating the conductors with a jacket member consisting of a non-magnetic material and conducting alternating currents whose phases are shifted by proper amount to the juxtaposed conductors in arranging order. CONSTITUTION:The conductor parts 4 are divided into proper number of sets where there are the same even-number of conductor parts, and the respective sets of conductor parts 4 are equally dispersed and arranged around a supporting body 3. Namely, in the case that the conductor parts are divided into (m) sets, the respective sets of conductor parts 4 are arranged in alternate (m-1) lines. As to the traveling direction of the conductor part 4 of each set, the traveling direction of the conductor L is reverse between to odd-numbered set of conductor parts 4 and the even-numbered set of conductor parts 4, so that the conductor parts 4A and 4B which belong to different sets are arranged to travel in the same direction in a state where they are arranged in two lines. By conducting the alternating currents of (m) kinds [(m) phases] whose phases are shifted by pi/m to the (m) sets of the conductor parts 4 in arranging order, progressive wave magnetic field which progresses in the direction of C is formed. Thus, the magnetic powder is carried without providing the mechanical rotating mecha nism.

Abstract: PURPOSE:To achieve power saving, so as to lengthen the life of a battery by detecting the oil level by making use of the fact that the electrifying state of a collector of a phototransistor to an emitter is changed on the basis of whether the oil level of the container into which oil is to be transferred reaches an oil level detector or not in an automatic stopper for an electrically-driven kerosene pump, etc. CONSTITUTION:When a switch 3 is turned on after inserting a pump part of a motor-driven pump into a container on the original side and also inserting the tip part of a drawing hose into a container on the transfer side, electrification is performed from a base 16 of a first transistor(Tr) 15 by the time constant of a delay circuit 26, and then the Tr 15 is turned on, and the output is input into bases 20, 21 of second and third Tr 19, 22, so as to make them into the turned-on state. As a result, a pump motor is driven, and the transfer of liquid is started. When light from a light emitting diode 13 of an oil level detector 11 does not enter the base of a photo Tr 14 after the oil level of the container into which oil is to be transferred is raised, the photo Tr 14 is turned off, and the Tr 15, 19, 22 are also turned off, thereby, the pump part is stopped.

Title: Production of pitch-based carbon filament mat
Inventor: YUMITORI SHUJI
IPC: D04H1/4242
Filed: 1991-04-22
Abstract: PURPOSE:To obtain a mat excellent in homogeneity in high yield by dropping spun pitch fiber onto an air stream permeable receiving member, sucking the air stream discharged from a high-speed air stream take-off device into a suction nozzle and applying moisture to the pitch fiber. CONSTITUTION:Melt spun pitch fiber is drafted with a high-speed air stream take-off device (air sucker) to produce a pitch-based carbon filament mat. In the process, the spun pitch fiber is dropped onto an air stream permeable receiving member and the air stream discharged from the high-speed air stream take- off device is forcibly sucked into an air stream suction nozzle set through the aforementioned receiving member oppositely to the high-speed air stream take- off device. Moisture is simultaneously and rapidly applied to the pitch fiber on the receiving member to provide a homogeneous mat form. Thereby, the pitch-based carbon filament mat in which the fiber is homogeneously dispersed is obtained without winding up or entangling the fiber in the receiving member with the discharged air stream.

Title: High speed paper transfer apparatus
Inventor: NAGASATO YOICHI
IPC: B65H9/14
Filed: 1985-06-04
Abstract: PURPOSE:To enable thin papers to be transferred with high speed and prevent troubles like offset of paper position by switching the transfer speed of papers to low speed and permitting the paper to collide with a stopping claw with low speed when the end of paper transferred with high speed approaches the paper stopping claw. CONSTITUTION:When an end 10 of a manuscript paper 1 passes right below a paper end position detecting means 19, a judging means 18 receives the detecting signal 191 to generate the selection signal 181 after standing by. A contact is changed over to a terminal 272 of a change-over switch 27 of a paper end position detecting means 17 to reduce the speed of a transfer motor 21, and the paper end collides with a paper stopping claw 8 to stop the proceeding. Thus, since the transfer speed is decelerated right before the stoppage, the paper end is not damaged by impact produced by the collision of the paper with the stopping claw 8 and the offset of stoppage position is not produced by the bound of the paper.

Abstract: PURPOSE:To perform the discrimination and positioning of an object regardless of the direction of the object by calculating the mean luminance level of N units of concentric circles centering on a point and then the absolute value of difference between said luminance level and the standard data. CONSTITUTION:N units of concentric circles having radiuses of multiples of (l) are formed centering on a point P, and N units of areas A1-AN are divided by those circles.

Then the absolute value or squared value is calculated for the absolute value of difference among N units of areas. Thus it is decided from the sum toal of the absolute or squared values that the smaller this sum total the more approximate both objects to be discriminated are to each other in terms of forms.
