Title: Heat insulation pot
Inventor: MIYAKE KAZUYA
IPC: A47J27/00
Filed: 1994-10-31
Abstract: PURPOSE: To prevent boiled rice from becoming rotten, even if a heat insulation operation stops at an intermediate process. CONSTITUTION: A heat insulation means 63 selects the temperature of boiled rice between high and low levels, thereby performing a hot insulation operation. When a power failure occurs and, then, a power source is reset during the heat insulation operation, the means 63 resumes the operation via a power reset means 73. In this case, the means 63 sets hot insulation temperature at a high level. Also, when the temperature of the boiled rice drops, due to a power failure, the propagation of putrefying bacteria is accelerated. After the power source is reset after a failure, however, the heat insulation temperature is set at a high level. Thus, the propagation of the bacteria is restrained, thereby enabling the boiled rice to be prevented from becoming rotten.

Title: Dust control process on combustive removal of carbon in ascension pipe in coke furnace
Inventor: YAMAMOTO YASUNORI
IPC: C10B45/00
Filed: 1993-10-26
Abstract: PURPOSE:To improve the environment around the coke furnace by allowing the dust exhausted from the top of the ascension pipe to the air to return to the furnace opening, sucking the dust with the dust collector above the opening to effect efficient prevention of dusting, when the carbon in the ascension pipe is combusted.

Title: Image detecting and recording device
Inventor: HAYAKAWA TAKESHI
IPC: G03C5/56
Filed: 1990-10-05
Abstract: PURPOSE:To record much information on a body to be measured which varies with time by irradiating a spatial optical modulating means with laser light and then irradiating a recording member with read light containing the read two-dimensional information. CONSTITUTION:When the light from the body 1 to be measured varies fast with time, an optical image formed on the photoelectric surface 10a of a spatial optical modulating tube 10 also varies fast with the time. Therefore, a charged image formed on the dielectric crystal 10b of the spatial optical modulating tube 10 also varies fast and its refractive index distribution, i.e. two-dimensional image also varies fast with the time. At this time, a variable wavelength laser light source 15 is designed so as to output the laser light which varies in wavelength with the time in synchronism with the time variation of the optical image from the body 1 to be measured. Then the read light which is outputted from the side of the dielectric crystal 10b has light information corresponding to the time variation of the light from the body 1 to be measured as two-dimensional phase information and corresponds to the wavelength variation of the read light. Consequently, the motion (time variation) of the body to be measured can be detected and recorded continuously as an image.

Title: Desentizing liquid for offset printing
Inventor: MOMOTAKE ISATO
IPC: B41N3/03
Filed: 1990-10-08
Abstract: PURPOSE:To enable formation of a film which eliminate a need to effect reinforcement by means of damping liquid and has extremely excellent hydrophilic property by a method wherein basic aluminum chloride is blended to prepare a desensitizing liquid for offset printing. CONSTITUTION:Desensitization is effected by means of a desensitizing liquid for offset printing containing basic aluminum chloride. The basic aluminum chloride is an inorganic polymer, so-called aluminum hydroxychloride, aluminum chlorohydoxide, or hydroxy aluminum chloride. Structure thereof is indicated by Aln(OH)mCl3n-m and basicity is different according to a value of (n) and (m). Basic aluminum chloride is often used as a coagulant for water treatment (aluminum polychloride : PAC). The desensitizing liquid for offset printing alone produces sufficient effect. However, when it is used in combination with a conventional desensitizing liquid consisting mainly of ferrocyanic compound, a ferricyanic compound, phytin acid, and different coagulants, the effect is further improved.

IPC: A47J37/06
Filed: 1994-11-01
Abstract: PURPOSE: To provide a cooker having a positive temperature characteristic by applying the constitution that a conductive film contains a binder of polyimide resin and a conductive inorganic substance having the specified grain size according to the preset ratio. CONSTITUTION: A cooker 10 has a pair of electrodes 2 at both ends of a flat insulation substrate 3, and a conductive film 1 containing a conductive material and a binder is laid between the electrodes 2. The conductive film 1 formed on the substrate 3 contains a binder at least made of polyimide resin, and metallic powder or silicide with a grain size between 1 and 20μm on the basis of a blending ratio between 1:1 and 1:6. As a result, the film 1 comes to have a positive temperature characteristic, and even if the temperature of cooking surface drops, due to the placement of a cooking ingredient thereon, power consumption becomes high and the temperature thereof quickly rises. Furthermore, power consumption becomes low, when temperature reaches the preset level.  Also, when the film 1 is made to contain an insulation filler having a mean grain size equal to or less than 10μm, the resistance value of the film 1 increases, and a resistance value for a heating film can be easily established.

Title: Production of polyarylene sulfide that yields little sulfur-containing gas
Inventor: YANAGIDA TAKUMI
IPC: C08G75/02
Filed: 1994-11-02
Abstract: PURPOSE: To obtain a polyarylene sulfide which is excellent in heat resistance and crystallinity and yields little sulfur-containing gas during heating and melting by reacting an alkali metal sulfide with two specified polyhalo aromatic compounds in two steps. CONSTITUTION: An alkali metal sulfide (e.g. sodium sulfide) is reacted with a polyhalo aromatic compound comprising 1,4-dihalobenzene or dihalonaphthalene. After completion of this main reaction, 1,3-dihalobenzene is added to effect reaction, thus giving a polyarylene sulfide. The suitable amount of the 1,3-dihalobenzene added in the second step is 0.005-0.1mol per mol of the alkali metal sulfide. Since the polyarylene sulfide thus obtained yields a reduced quantity of sulfur-containing gas during heating and melting, it hardly causes corrosion of a mold during molding and is therefore suitable for the production of injection-molded articles, extruded articles, blow-molded articles, etc.
