Title: Oxidation hair dyeing method requring preliminary contact treatment
Inventor: GOTSUTOFURIIDO UENKE
IPC: A61K8/58
Filed: 1992-03-06
Abstract: PURPOSE: To make the dyeing rate of virgin hair coincide with that of treated hair when dyeing the hair according to an oxidative hair dyeing method, shorten the hair dyeing time and uniformize the color applied to the virgin and treated hair parts. CONSTITUTION: (a) An aqueous solution of a transition metal (especially copper-II) ion forming a complex with a chelating agent selected from 2,2'- dipyridyl and 0-phenanthroline is brought into contact with hair to deposit the complex in a uncoloring amount effective in catalytic actions on the hair and carry out pretreatment when dyeing hair having virgin and untreated hair parts according to an oxidative hair dyeing method. (b) The pretreated hair is then brought into contact with an oxidative dye mixture comprising a dye precursor and an oxidizing agent (especially hydrogen peroxide), preferably at pH6-8.5 for 5-30min. Thereby, the time for the hair to produce a hue of a desired coloring therein is substantially shortened to reduce damage to the hair. The color applied to the untreated and treated hair parts is substantially uniformized.

Title: Pump valve with constant resistance
Inventor: TAKI TOMOHIKO
IPC: F04B53/00
Filed: 1980-07-18
Abstract: PURPOSE: To protect pump from overcharge by automatically generating a water flow resistance to conform with the height of pressure of the pressure giving water supply pool by a method to detect such pressure with a diaphragm thus to control the water flow area with a vertical movement of the resisting element to meet the detected pressure value.  
     CONSTITUTION: Pressure giving water in the water pool 3 is pumped up by the pump 1 through constant resistance valve 2. At this time, the water pipe 4 has a positive pressure inside because the input side of pump 1 is under pressure. This positive pressure is given to the diaphragm 16 of the constant resistance valve 2 and is changed to a force by the retainer 19 and brings the resistance element 14 upward by the rod 20. Wtih this up-lifting action, the resistance element 14 moves to the direction to close the valve seat 12, reduce the area of the flow passage, and to generate a water flow resistance to conform with the pressure height. In this way, the overcharge of the pump is always prevented irrespective of any change of the pressure height.

Title: Image forming device
Inventor: OZEKI YUKIHIRO
IPC: G03G15/36
Filed: 1994-04-11
Abstract: PURPOSE:To eliminate the misalignment of images caused when two images are superposed on a recording material. CONSTITUTION:The black-and-white toner image is formed by a first electrophotographic image forming means I on the upstream side and the color ink image is formed by a second ink jetting type image forming means II on a downstream side. The length of the recording material P shrinks in a carrying direction when it is passed through the heat fixing device 12 of the image forming means I. The shrinkage of the material P is detected by the light emitting part 32a and the light receiving part 32b of a size detection means 32 and a correction value is calculated by a correction means 51. Based on the correction value, an image writing position is corrected when the image is formed by the second image forming means II. Thus, the ink image can be superposed on the material P shrinking when the toner image is formed without causing the deviation of the images.

Title: Sheet-shaped composite material and gasket
Inventor: ISHII YOSHITO
IPC: C09J7/02
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To be used for gaskets and packing which have good heat resistance, sealing property, and high strength by a method in which a reinforcing core material and a sealing material are laminated using a resin containing a dihydrobenzooxazine ring in a molecule as an adhesive so that the surface layer of one side or both sides is a sealing material. SOLUTION: In order to laminate a sheet material composed of a reinforcing core material and a expanded graphite sheet, a resin containing a dihydrobenzooxazine ring in a molecule is used as an adhesive. By using the adhesive, since heat resistance is improved and the generation of volatile gas during curing can be controlled, the swelling of a produced sheet-shaped composite material can be controlled, adhesion between the reinforcing core material and the sealing material is improved, and properties such as sealing improve. In the adhesion between the core material and the sealing material, after the resin containing the dihydrobenzooxazine rings being applied on either the core material or the sealing material or both of them, the core material and the sealing material are laminated alternately and hot-pressed.

Title: Optical communication system
Inventor: NAGANO MUNEHIKO
IPC: H04B10/2507
Filed: 1978-08-11
Abstract: PURPOSE:To shorten the transmission band by combining the optical signals sent from the digital information source and the analog signal source via the optical coupler to send the combined signal to one piece of fiber and then transmitting the analog signal featuring a small amount of the leak along with the digital signal with a simple circuit. CONSTITUTION:Code converter 2 converts the digital signal sent from digital information source 1 in to such code as to feature the combination of the binary code pulses to give a fixed DC level to the digital optical signal. And the low frequency component contained in the transmitted digital optical modulation signal is removed through low band cut-of filter 3. Then the signals which are arranged to from the low frequency component region with elimination of the analog signal component are delivered from analog signal source 8. The optical signals from information source 1 and signal source 8 are combined via optical coupler 7 to be sent out to a piece of optical fiber. Thus the analog signal featuring a small amount of the leak noise is transmitted along with the digital signal through a simple circuit, shortening the necessary transmission band for the optical fiber.
