Title: Method of removing hair from machine
Inventor: NAKAYAMA YOSHIO
IPC: C02F1/00
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To easily and surely remove hair entangled obstinately to a machine such as waste water treatment machine or intruding into detail parts by decomposing and removing the hair entangled to the machine by using a protein decomposition enzyme. SOLUTION: For example, a net-like screen 1 used in a water treatment machine experiences clogging of a screen net due to fine dust 3 such as hair captured and the like after a continuous use so that filtration performance is deteriorated. The fine dust 3 has to be removed. This can be performed periodically without regard to deterioration of filtration performance or can be performed nonperiodically by detecting deterioration of the filtration performance, but in either case the net-like screen 1 is lifted from a flow path 2 and is immersed into a hair removing tank containing a solution of a protein decomposition enzyme capable of decomposing the hair biochemically. By this method, the hair captured by the net-like screen 1, including the hair entangled obstinately, can surely be decomposed.

Title: Method for joining aluminum or aluminum alloy
Inventor: KUDO HAJIME
IPC: B23K35/28
Filed: 1989-07-04
Abstract: PURPOSE:To well braze the joint part of aluminum or aluminum alloy without melting this part by supplying a compsn. contg. metallic powder for brazing having a limited m.p. and a binder which evaporates at a brazing temp. to the joint part of Al or Al alloy, further interposing a flux therein and heating the joint part. CONSTITUTION:A Zn-Al alloy is used as the metallic powder for brazing of the aluminum or aluminum alloy having about 340 to 550 deg.C m.p.. The reason for limiting the m.p. is that a problem arises in the joint strength if the m.p. is below the limit and the base metal melts if the m.p. exceeds the limit. An org. resin which evaporates before decomposition carbonization when heated by brazing, i.e. an acrylic resin of about 1,000 to 100,000mol.wt. is used as the binder. The metallic powder for brazing and the binder are so compounded as to attain about 10 to 5,000cps viscosity. The mixture is stuck to the joint part and if necessery an aq. soln. of a flux having the m.p. near the m.p. of the brazing material is applied to the joint part. The brazing is thus executed.

Filed: 1990-06-28
Abstract: PURPOSE:To certainly reduce a dent by a method wherein a release film to which a metal foil is preliminarily bonded in a separate place is superposed on a prepreg so that the metal foil comes into contact with the prepreg to form a laminated material which is, in turn, held between mirror plates to be molded under heating and pressure by a press. CONSTITUTION:A metal foil 2 is superposed on a set composed of superposed prepregs 1 and a release film to which other metal foil 2 is preliminarily bonded by an adhesive tape 5 is superposed on the set 1 of the prepregs so that the metal foil 2 comes into contact with the prepregs 1 to constitute a laminated material which is, in turn, held between mirror plates 4 and molded under heating and pressure by a press to obtain a metal foil clad laminated sheet. Since the release film and the metal foil are preliminarily bonded in other place, it is prevented that a resin powder and waste yarn penetrate in the gap between both of them. The dent based on the resin powder penetrating in the gap between the release film and the metal foil is not generated.

Title: Moisture permeable and moisture condensation preventive wallpaper, and preparation thereof
Inventor: YAMAMURA SACHIKO
IPC: B32B5/18
Filed: 1988-07-09
Abstract: PURPOSE:To obtain the title wallpaper having moisture condensation preventive effect and excellent in antistaining properties by laminating and fixing a moisture permeable resin foam layer composed of a closed cell structure to the surface of decorative paper while laminating and fixing base paper to the rear of said decorative paper. CONSTITUTION:A moisture permeable resin layer 1 or a resin foam layer 1 substantially composed of closed cells 5 is laminated and fixed to the surface of decorative paper 2. Therefore, moisture in the atmosphere passes through the relatively thin moisture permeable resin layer 1 to enter the interior of this laminated structure in the thickness direction within a short time. When a moisture absorbent 6 is dispersed in the decorative paper 2 or the resin layer 1, said moisture is rapidly absorbed. When an adhesive layer 3 has moisture permeability, moisture is further propagated to base paper 4 through the adhesive layer 3 to be absorbed by said base paper 4. Since much moisture is absorbed if the moisture absorbent 6 is dispersed in the adhesive layer 3, still more effect is obtained. Contrarily, when a room becomes a dry state, excellent moisture absorbing and discharging characteristics are again developed through the moisture permeable resin layer 1 and, as a result of this respiration action, a moisture condensation phenomenon on a wall surface is suppressed.

Abstract: PURPOSE:To improve the quality of a product by molding an intermediate rough shape billet having an under-filled shoulder part and subjecting the billet to shaping rolling of flanges and universal rolling to bring the same into contact with vertical rolls and horizontal rolls. CONSTITUTION:The billet is subjected to rough caliber rolling to preliminarily round the shoulder part 1 opposite to the projection of the product to form the under fill state as compared to the product to the shoulder part 1. The billet is then subjected to several passes of universal rollings to obtain the balances of the respective parts including the projection with the right and left vertical rolls 3a, 3b and the upper and lower horizontal rolls 2, 4. The load acting on the upper horizontal roll 2 is supported by the vertical roll 3a. After the billet is further subjected to shaping caliber rolling, the billet is subjected to finish rolling, by which the horizontal rolls 5, 6 and vertical rolls 7, 8 are brought into contact with the billet. Since the intermediate rough rolling is executed by forming the round part to the shoulder part 1, the dimensional accuracy of the product is improved and the need for the build up repair of the rolls, etc., is eliminated.

Title: Charge transfer device
Inventor: AOKI TADASHI
IPC: H04N5/335
Filed: 1984-08-17
Abstract: PURPOSE:To increase a transfer rate by forming three or more of reverse conduction type regions having mutually different concentration per one bit onto a substrate. CONSTITUTION:N well regions 12-14 are shaped to a P type substrate 11. The regions 12 are maximized and the regions 14 are minimized in concentration. 15, 16 represent storage gates and 17 barrier gates. An electrode P1 applying phi1 pulses and an electrode P2 applying phi2 pulses each have three gate structure, and there are differences among the potential of several electrode P1, P2 by differences among the concentration of the regions 12-14 under respective gate even when pulses phi1, phi2 are at a low level as time t1. Pulses phi1 are at a high level on the timing of time t2, and transfer charges 19 are stored under the gates 15, 16. Since pulses phi1 are at the low level and pulses phi2 at the high level at t3, charges 19 are transferred under the gates 15, 16. In the constitution, gate length is shortened even when pitches are the same. Since a transfer rate is inversely proportional to the square of gate length, the transfer rate is increased by twice or more according to the constitution.

IPC: G11C7/12
Filed: 1982-09-30
Abstract: PURPOSE:To read out stored contents of memory cells at a high speed without destroying them, by providing a reset signal generating circuit to reset a memory circuit block. CONSTITUTION:A delay circuit DL delays a pulse phi0, which is outputted from an address change detecting circuit CNG, by a time td longer than the access time to generate a pulse signal, and a reset signal generating circuit RG generates a reset signal phi1 which rises in accordance with the rise of the output pulse of the delay circuit DL and falls in accordance with the rise of the first pulse phi1 after the delay time td. After bit lines BL and BL' are reset to the middle level by the reset signal phi1, a word line WL is set to the L level. Since the reset signal phi1 is generated before the address change to prepare for the next cycle, potentials of bit lines BL and BL' are already reset to the middle level between the H level and the L level at the address change time, and thus, bit lines BL and BL' are changed quickly to the H level and the L level in accordance with contents of a memory cell MC without destroying them.
