Title: Method for regularly bundling hollow yarn membranes
Inventor: MIURA TAKASHI
IPC: B01D63/02
Filed: 1985-08-30
Abstract: PURPOSE:To bundle fragile hollow yarn membranes to obtain the bundle of membranes which is not twisted and bent by holding the upper part of the bundle in the regularly bundling process, sprinkling water from the upper periphery of the bundle to the lower part and properly arranging the bundle with the water current. CONSTITUTION:One end of the properly arranged bundle of a specified number of hollow yarns is fixed. The fixed part is held with the fixed part as the upper part so that the bundle is vertically hung. Water is sprinkled over the bundle directly under the fixed part from >=3 nozzles at a specified injection angle. At this time, the whole bundle is fractionally moved in the horizontal and the vertical direction.

Filed: 1990-07-18
Abstract: PURPOSE:To uniformize the action of respective emitter regions of a bipolar transistor and to improve power gain by making an insulating film instead of a photoresist film serve as a mask in the step of the second ion implantation. CONSTITUTION:After covering the region except an emitter opening 5 with a photoresist film 13, a photoresist film 13 is used as a mask in the step of the second ion implantation to implant an N-type impurity (arsenic or phosphorus) at a dose of 5X10<15>cm<-2>, whereby the N-type polysilicon film 6a is converted into an N<+> type polysilicon film 6b. After removal of the photoresist film 13, the film 6b is diffused as the diffusion source to form an emitter region 7 in self alignment. Successively formed are a source insulating film 9 having an emitter contact opening 8 and an emitter electrode 10 made of gold or aluminum.

Abstract: PURPOSE:To attain a microminiature structure of a magnetic recording/reproducing device by setting the height of the top face of a tape guide drum lower than the height of the open front cover of a loaded tape cassette and setting the front cover of the tape cassette so that it covers over the upper side of the guide drum. CONSTITUTION:A magnetic recording/reproducing device 1 contains a miniature tape guide drum 2 and a miniature tape cassette 3 which are set close to each other. The tape guide pole group is also set close to the drum 2. Thus the size of the device 1 is miniaturized significantly compared with a conventional type. In addition, the device 1 has four video heads distributed with a 90 deg. space respectively with the drum 2 set inside. Thus a magnetic tape 4 is wound about 270 deg. over 180 deg. by the guide pole, and the video heads are actuated successively with switching in a range of tape touch angles for each minus operation. As a result, a track pattern equal to the present one is formed on the tape 4. This ensures interchangeability with an existing device.

Title: Method for mold release and porous glass mold used therefor
Inventor: TOMONO HARUO
IPC: B29C33/46
Filed: 1986-08-15
Abstract: PURPOSE:To make it possible to release a molded item from a mold without deforming the molded item and consequently prevent the stain with release agent from leaving on the surface of the molded item by a method wherein the molded item is released from the mold by applying gas pressure from the surface of the cavity of the mold made of porous glass to the molded item. CONSTITUTION:A molded item is released from a mold by utilizing the pressure of gas, which is developed to the molded item contacting with the mold through pores in the interior of the mold, by abruptly forcing compressed gas such as compressed air or the like into the pores of the porous glass mold. For example, the compressed gas 4 is flowed under the state that a gas forcing-in jig 3 is brought into close contact with the top surface 2a of the mold. Any jig will do as far as gas can be supplied into the pores of the mold 2 as the gas forcing-in jig 3, In addition, as the gas, there is no limit on its kind and practically compressed air, which is cheap and easily obtainable, or the like is convenient. Further, the higher the pressure becomes, the easier the molded item tends to be released. However the pressure is properly set in accordance with the pore diameter, number of pores of the porous glass, the order of bonding of resin to the glass and the like. For example, the rising of pressure up to the desired value in 0.05-0.5sec by means of a manual cock or solenoid valve is enough for releasing.

Abstract: PURPOSE:To simplify a structure of an ink jet head, multiply the heads, and gather multi-heads by forming an electrostrictive vibrator of ink jet heads into a comb-like shape and arranging the toothed part in an ink chamber so as to be integrated. CONSTITUTION:Each toothed part 2a of a comb-like electrostrictive vibrator 2 of ink jet heads 1 is arranged in a position just under an orifice 5d and a partition wall 5a of an outer frame 5 and the oscillator 2 are fixed by adhesion or compression bonding so as to be integrated. After ink is extruded, ink grains 10 left outside the orifice 5d are extruded in an ejected state and continue flying, for example, in the direction of a recording paper. In an ink chamber 5b, the ink reduces by a volume of the ejected ink grains 10, so that an ink quantity equivalent to the reduced quantity is replenished from an ink supply passage 5e and a state of the ink chamber 5b filled with the ink is restored. Such an operation is repeated in the individual ink chamber 5b of the multiplied head 1, so that desired ink grains 10 can be ejected selectively and continuously.
