Title: Manufacture of surface sheet for concrete placing form
Inventor: YANO YASUYOSHI
IPC: E04G9/10
Filed: 1990-04-24
Abstract: PURPOSE:To improve releasability from concrete and water absorption and drainage properties by piercing heating needles from a nonwoven cloth side to open holes when a plastic film and nonwoven laminate formed with many water permeable holes manufactured. CONSTITUTION:A nonwoven fabric 2 and a nonwater permeable plastic film 3 are laminated to form a laminated 4. Then, heated needles 4 are pierced from the fabric 2 side of the laminate 4 to form many water permeable holes 6. Then, the concrete placed side of a form is coated with the laminate 4 with the fabric 2 side disposed inside. Concrete is placed at the film 3 side, and moisture generated from the concrete is drained from the holes 6. Thus, since the diameters of the holes 6 are larger at the fabric 3 side than at the film 3 side, water can be satisfactorily absorbed and drained. Since the fiber of the fabric 2 is not exposed, a smooth concrete surface can be formed.

Title: Fining and releasing device for air bubble in liquid
Inventor: ARAI KOUZOU
IPC: C22B21/06
Filed: 1980-08-05
Abstract: PURPOSE:To make contact of gas and liquid wide and uniform by feeding gas from the top of a liquid tank down to near its bottom by means of a hollow revolving shaft, mounting a rotator to the bottom end of the revolving shaft, dispersing air bubbles between the bottom surface thereof and the tank bottom and fining the air bubbles by centrifugal forces and revolutions. CONSTITUTION:For example, molten aluminum 4 is put into a liquid tank 1, and a hollow revolving shaft 2 is put perpendicularly into this. A rotator 3 is mounted to the bottom end of said shaft in such a way as to revolve together with the shaft 2. The bottom surface of the rotator 3 maintains a prescribed spacing, for example, 5-100mm. spacings, from the bottom of the tank 1, so that air bubbles air blown out from this clearance. Gaseous argon and nitrogen are fined by the revolutions of the rotator 3 and centrifugal forces and disperse into the molten aluminum 4, which is brought into contact with these by large surface areas on account of the fine bubbles and is thereby thoroughly agitated and mixed. The gaseous hydrogen in the molten aluminum 4 is captured by these and is thus removed.

Title: Power supply circuit
Inventor: SAKO MICHIYA
IPC: G05F3/22
Filed: 1988-04-28
Abstract: PURPOSE:To eliminate a need of generation of difficult resistances for integration and to freely change the current limiting of high precision by incorporating several transistors (TRs) different in area ratio to detect current limiting. CONSTITUTION:When external terminals 9 and 10 are connected to an output terminal 8, respective emitter currents I2 and I3 of NPN TRs 2 and 3 having the common base are given by I2=S2/S1.I1 and I3=S3/S1.I1 where S1, S2, and S3 are emitter areas of an NPN TR 1 and TRs 2 and 3 respectively. When the area ratio of current mirror PNP TRs 4 and 5 is 1:1, a voltage VBE of an NPN TR 6 as the output current limiting TR is generated by R7.I4, where I4 is the collector current of a PNP TR 5 and R7 is the resistance value of a resistance 7, to limit the output current. Thus, it is unnecessary to generate a difficult resistance for integration, and current limiting of high precision is freely changed.

Title: Laser beam machining process
Inventor: KONDO HIROAKI
IPC: B23K26/08
Filed: 1987-04-30
Abstract: PURPOSE:To reduce the machining time to the extent of omission of the X direction scanning at an unmachining area by carrying out continuously the step movement in the Y direction between machining areas and skipping from the last X direction scanning of one machining area to the first X direction scanning of a next machining area. CONSTITUTION:When the machining of a machining area 2 is finished and a Y table 9 is further moved, an optical sensor 12 detects reflected light from a tape 15. A control means 11 receiving this detected signal sends a continuous driving signal to a stepping motor 10. The continuous movement of the Y table continues till the optical sensor 12 ceases to detect the reflected light and when it enters a range B of a machining area 3, the control means 11 stops the movement of the Y table 9. Then, an X table 4 starts to move to the right side and the same operation as the that at the machining area 2 is started. Accordingly, the X direction scanning at a range C is not performed, so the machining time to the extent of the omission of the scanning is reduced.

Title: Transparent sheet containing directional image
Inventor: PORTER GERALD R
IPC: G06K19/14
Filed: 1986-05-12
Abstract: This invention concerns a transparent sheet containing a directional image and method for forming such a sheet. A directional image is created in a transparent sheet comprising a monolayer of microlenses by forming deformations or axial markings in at least some of the microlenses by irradiation with a laser beam. The sheet may further comprise a partially light transmissive mirror disposed behind at least some of the microlenses. The directional images may be formed in transparent sheet which has been applied to a document as an overlay. When viewed under diffuse lighting conditions, the deformations appear as a dark image. The deformations may be formed so that when viewed under retroreflective conditions within a conical field the image is darker than the surrounding background, and when viewed under retroreflective conditions outside the conical field the image is brighter than the surrounding background.

Abstract: PURPOSE:To easily generate and output a frequency being N times of that of an input pulse train by providing a storage section storing the timing of the input pulse train and driving an N-time timing generating section based on the timing read from the said storage section. CONSTITUTION:A timing extracting section 11 extracts the timing when the input pulse train IN is generated. A timing storage section 12 stores the extracted timing. For example, when M-set of pulses from the arrival of a synchronizing pulse SYNC till the arrival of the next synchronizing pulse SYNC are given as input pulses, the storage section 12 stores M-set of timings. After the 2nd and succeeding synchronizing pulses SYNC come, a timing read section 13 reads a timing from the storage section 12 in a form of a period T1 and gives it to an N-time timing generating section 14 every time a pulse appears as the input pulse train IN. The generating section 14 outputs an output pulse train OUT having a period of T1/N.

Filed: 1990-04-25
Abstract: PURPOSE:To improve adhesion of a paint film and prevent cracks and separation of the paint film due to processing by forming an oxidized film with a specific thickness on a material for use in fins by effecting AC electrolysis in an alkaline aqueous solution. CONSTITUTION:An aluminum or aluminum alloy is subjected to AC electrolysis in an alkaline aqueous solution at pH 9-3, temperatures 35-85 deg.C, current density 4-50A/dm<2>, and quantity of electricity exceeding 80C/dm<2> to form an oxidized film with a thickness of 500-5,000Angstrom . Either or both anti-correction film and hydrophilic film are applied to the oxidized film thus formed. Since the oxidized film has a large pore diameter and a large number of branches, a strong adhesion is achieved between a paint film and an aluminum plate when an organic substance such as coating resin etc., or an inorganic substance such as water glass etc., is applied to the oxidized film. The oxidized film is flexible and hence cracks or separation is not formed therein, so that cracks or separation is not caused by processing in the resins or inorganic paint films applied to the surface of the oxidized film.
