Patent number: 8763304Abstract: A method for producing a rooted cutting which can be applied to Pinaceae trees. Specifically, the present invention provides a method for producing a rooted cutting of a Pinaceae tree, comprising the following steps A and B: A: adding a cytokinin to the outside of a shoot apex of a short shoot of a Pinaceae tree to thereby induce a new scaly leaf and/or primary leaf; and B: cutting out the short shoot where new scaly leaf and/or primary leaf is induced in the step A, inserting the short shoot as a cutting in a rooting bed wetted with a carbon source-free liquid medium comprising nitrogen, phosphorus and potassium as essential elements, and culturing the short shoot in a culturing vessel while regulating the concentration of CO2 gas in the culturing vessel at a humidity of 80% or more to root the cutting.Type: GrantFiled: June 10, 2008Date of Patent: July 1, 2014Assignee: Nippon Paper Industries Co., Ltd.Inventors: Hiroshi Tachikawa, Chikahiro Miyake

Publication number: 20090173696Abstract: In an activated sludge treatment of organic waste water, excess sludge from the activated sludge aeration vessel is processed with hypochlorous acid in place of ozone without set up of aeration vessels and blowers to improve volume reduction cost of sludge without deterioration of water quality. The hypochlorous acid process is carried out by using an acidulous sodium hypochlorite aqueous solution which is prepared by mixing sodium hypochlorite aqueous solution with a dilute hydrochloric acid and diluting the resulting mixture with water within 1,000 ppm to 50,000 ppm of available chlorine concentration at a pH zone of more than 4 to less than 7.Type: ApplicationFiled: March 26, 2007Publication date: July 9, 2009Applicant: ES.

Publication number: 20090114353Abstract: An inventive method of papermaking can be provided for creating an optimum wet end environment. In a preferred method, an aqueous solution of sodium hypochlorite acidified by hydrochloric acid to have a pH of greater than or equal to 4 and less than 7 and adjusted to have an effective chlorine concentration of 1,000 to 10,000 ppm, preferably 3,000 to 8,000 ppm is prepared and charged to a white water pit in a manner to be effective chlorine concentration therein to greater than or equal to 0.5 ppm. Before a step of papermaking, it is preferred that aqueous solution sodium hypochlorite having pH of greater than or equal to 4 and less than 7 is added continuously or intermittently to a raw material water with the expectation that at breaching a residual chlorine concentration becomes greater than or equal to 500 ppm.Type: ApplicationFiled: December 14, 2005Publication date: May 7, 2009Applicant: HSP HANBAI KABUSHIKI KAISHAInventors: Tsugio Tachikawa, Hiroshi Tachikawa, Hideo Tachikawa

Patent number: 5764316Abstract: A lighting system has a light source (2), a liquid crystal dimmer plate (4) for scattering a desired quantity of light from the light source (2), and a control power supply (5) for controlling a light scattering rate or effect of the liquid crystal dimmer plate (4). A light component transmitted through the liquid crystal dimmer plate (4) can be controlled by controlling the scattering effect of the dimmer plate (4). The so controlled light can be used as an illuminating light for a camera for example.Type: GrantFiled: September 28, 1993Date of Patent: June 9, 1998Assignees: Nippon Hoso Kyokai, Sumitomo Electric Industries, Ltd.Inventors: Kuniharu Takizawa, Hideo Fujikake, Hiroshi Tachikawa, Osamu Kobayashi, Yoshiaki Tanaka, Masanori Nakamura, Takamichi Kasahara, Kensaku Takata, Morihiko Katsuda, Tohru Kashiwagi

Patent number: 5594286Abstract: A control circuit for controlling a plurality of power supply modules connected in parallel to provide power to a single load. The control module first converts first analog data corresponding to a voltage level which is applied to the load. The control module then compares the voltage level to a predetermined voltage level and computes a voltage deviation between the predetermined voltage level and the voltage applied to the load. The control module then computes whether the voltage deviation is within a proper limit or not. The control module then sends a pulse width data signal corresponding to the voltage deviation to the power supply modules in order to control the amount of power each module supplies to the load.Type: GrantFiled: July 2, 1993Date of Patent: January 14, 1997Assignee: NEC CorporationInventor: Hiroshi Tachikawa

Patent number: 5559376Abstract: In a power supply control system including first through N-th power supply units for generating first through N-th output voltages, the first through the N-th power supply units producing first through N-th failure signals on occurrence of failure in the first through the N-th power supply units, respectively. A sequence control unit carries out a power on sequence which is for sequentially putting the first through the N-th power supply units into an on state in voltage increasing order of the output voltages and carries out a power off sequence which is for sequentially putting the first through the N-th power supply units into an off state in voltage decreasing order of the output voltages.Type: GrantFiled: January 29, 1993Date of Patent: September 24, 1996Assignee: NEC CorporationInventor: Hiroshi Tachikawa

Patent number: 4820237Abstract: A coin stacking apparatus includes a conveyor for conveying coins edge-wise one at a time and delivering each of the conveyed coins in its horizontal position. A receiver receives the coins from the outlet end of the conveyor in a stacked condition. The receiver includes two endless belts running along the length of the receiver and cooperating with each other to form a coin receiving space therebetween. Each of the endless belts has a supporter extending therefrom. The supporter includes a surface on which the coins are to be placed. The surface is inclined upwardly and forwardly relative to the direction of the conveyor.Type: GrantFiled: February 18, 1987Date of Patent: April 11, 1989Assignee: Laurel Bank Machines Co., Ltd.Inventors: Takashi Shinozaki, Hiroshi Tachikawa

Patent number: 4136273Abstract: A method for TIG welding by using a plurality of nonconsumable electrodes extending frm the tip of a TIG welding torch and one filler wire fed through a space between the electrodes, each electrode being independently supplied with power. A molten pool is formed by melting both the base metal to be welded and the filler wire by means of arcs generated between respective electrodes and the base metal. Melting of the base metal is mainly controlled by the arc produced by one of the plurality of electrodes while melting of the filler wire is mainly controlled by the arc generated by the other electrode.Type: GrantFiled: March 4, 1977Date of Patent: January 23, 1979Assignee: Nippon Steel CorporationInventors: Haruo Eujita, Yasushi Ishikawa, Hiroshi Tachikawa, Taizo Nakamura
