Title: Radiant space heater
Inventor: YAMAMOTO TERUO
IPC: F24C7/04
Filed: 1989-11-17
Abstract: PURPOSE:To enable a user to obtain an optimum warm feeling on each occasion from the starting of the operation of the present heater until the stabilization of indoor circumstances by changing a radiant heat flux density that is allowed to act on a user's body in accordance with its temperature feeling. CONSTITUTION:When the present device starts to operate, a radiant heater 1 is lighted and an infrared ray sensor 4 detects the presence of a user and his skin temperature T. If the detected value is lower than a first preset temperature Ta1, a movable reflecting plate 2b is turned inwardly so as to increase a radiant heat flux density to provide a first radiant heat flux density whose radiant heat is projected onto a user's body, thereby giving a warm feeling soon to the user even when he feels cold. Thereafter, at a point of time when the skin temperature T reaches the first preset temperature Ta1, the movable reflecting plate 2b is turned outwardly so as to provide a second radiant heat flux density whose radiant heat is projected onto the whole body including the arms and legs. When the user's warm feeling is fairly satisfied, the movable reflecting plate 2b is further turned outwardly so as to provide a third radiant heat flux density whose radiant heat heats the wall surfaces and the floor plane in the room, so that secondary radiant heat therefrom serves to warm the body from user's surroundings thus providing comfortable heating effects.

Title: Gas detecting element
Inventor: KUBOTA KAZUNARI
IPC: G01N27/16
Filed: 1989-11-21
Abstract: PURPOSE:To increase the output of the gas detecting element and to simplify an electronic circuit for amplification by forming the element in such a manner that the temp. rise of a catalyst carrier at the time of contact with a combustible gas propagates to a platinum coil. CONSTITUTION:The platinum coil 1 is embedded in the central part of the catalyst carrier 2 formed by coupling aluminum nitride 4 with alumina 5. An oxidizing catalyst 3 is deposited on the catalyst carrier 2. The platinum wire coil 1 is adapted to be embedded into the catalyst carrier 2 and transmits the change in resistance by a temp. change. The oxidizing catalyst 3 is deposited on the catalyst carrier 2 and burns the combustible gas to increase the temp. of the catalyst carrier 2 and the platinum wire coil 1. Since the combustible gas burns on the surface of the catalyst carrier 2 and near this surface, the temp. rise takes place on the surface of the catalyst carrier 2 or near this surface and propagates into the catalyst carrier 2. The thermal conductivity of the aluminum nitride 4 is as high as >=10 times the thermal conductivity of the alumina 5 and, therefore, the temp. rise on the surface of the carrier or near the same propagates effectively to the platinum wire coil 1.

IPC: B41J2/36
Filed: 1987-12-02
Abstract: PURPOSE:To make a relation between a recording dot number and an image density as ideal as possible, by a method wherein with respect to a recording pulse to be applied to a heating element disposed on a thermal head an energy is kept nearly constant and a pulse width is varied corresponding to the number of recording dots outputted from a gradation level holding means. CONSTITUTION:From an inputted data signal of a thermal printer 10, a recording dot number (n) of data of a gradation level to be recorded is temporarily stored in a gradation level holding means 12. In a recording pulse width varying means 15, a recording pulse is applied to a heating element disposed on a thermal head 14 with an energy kept nearly constant and a pulse width varied corresponding to the recording dot number (n) inputted from the gradation level holding means 12 to make a relation between the recording dot number (n) and a pixel density an ideal curve, whereby an input/output relation is determined. Because the recording signal is printed by a pulse width varied in this manner, the value of a pixel density O.D. to the recording dot number (n) becomes ideal characteristics.

Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To facilitate the desalting treatment of waste water by cooling feed raw water (waste water) to a prescribed temp. and thereafter, allowing the raw water to permeate through reverse osmosis membranes. SOLUTION: In this water treatment, a leachate that contains salts and is discharged from a waste disposal site, is introduced into a cooling tower as feed raw water and there, the raw water is cooled to an about <=35 deg.C temp. at which such water can be treated with conventional reverse osmosis membranes, to prevent the desalting capacity of the reverse osmosis membranes from being adversely affected because of high temp. Then, the cooled raw water is introduced into a reverse osmosis membrane device 1 to subject the raw water to desalting and the resulting concentrated water is introduced into an NF(nanofilter) membrane device 2 and there, salts, particularly divalent or higher negative ions in the form of CaCO3 , etc., in the water is filtered off and removed.  At this time, the permeant water formed in the NF membrane device 2 is treated with a high pressure reverse osmosis membrane device 3 and then, withdrawn as highly concentrated water from the device 3. Further, the concentrated water formed in the NF membrane device 2 and also, one portion of the highly concentrated water formed in the high pressure reverse osmosis membrane device 3 are supplied to a crystallization vessel 4 to solidify salts and remove them as solid matter and at this time, the supernatant is returned to the NF membrane device 2. Thus, even high temp. raw water can be allowed to permeate through the reverse osmosis membranes without causing any damage to the membranes and the need of using any large adjustment vessel can be eliminated.
