Title: Oil absorbable building material, oil content generating equipment and kitchen
Inventor: KIGAMI MAKOTO
IPC: E04F13/14
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To keep beautiful appearance of a wall or a ceiling for a long period of time without wiping off oil content by executing a graze on the surface of an oil absorbable building material body. SOLUTION: It is important to control the area to be treated with a glaze or thickness of the glazed area so as to obtain a glazed building material capable of maintaining high oil-absorbing performance. That is, it is preferable that the ratio of the surface of a glass layer formed by glazing to the surface of an oil absorbable building material body is not more than 90% or the maximum thickness of the formed glass layer is controlled to be not more than 300 μm. As the glaze, a slurry obtained by simply mixing frit and water and having a specific gravity of 1.01 to 1.90 can be used or a slurry obtained by further adding clay or a pigment to the slurry mentioned above can be used. This oil-absorbable building material is preferably used as a material being stuck on the wall or the ceiling of the room having oil-generating sources such as a kitchen.  In the case when the oil- absorbable building material is executed onto the wall or the ceiling in the vicinity of a gas range, even when the oil component generated at the time of cooking fixes on the surface, the oil component diffuses into the inside of the oil absorbable building material and the surface of the wall or the ceiling is prevented from being made sticky by the oil component.

Title: Magnetic recording and reproducing device
Inventor: TERANISHI KEIICHI
IPC: G11B5/02
Filed: 1988-08-29
Abstract: PURPOSE:To realize a high S/N with small crosstalk and to reproduce a signal without mis-detection by constituting a channel connecting to a preceding head and a channel connecting to a succeeding head so that they are not adjacent to each other on a rotary transformer. CONSTITUTION:On the rotary transformer 5, a channel 2ch connecting to a preceding A head 3a and a channel 4ch connecting to a succeeding B head 2b, and a channel 3ch connecting to a preceding B head 3b and a channel 1ch connecting to a succeeding A head 2a are formed so as not to be adjacent to each other. The crosstalk of the rotary transformer 5 is highest between adjacent channels and the crosstalk is extremely reduced with an interval of 1channel. Thus, the high S/N reproduction system with less crosstalk from an option track to the main track is realized and the signal is reproduced without mis-detection.

Title: Electric stove
Inventor: HASHIKAWA KIICHI
IPC: F24C7/04
Filed: 1988-08-29
Abstract: PURPOSE:To ensure that a power supply is switched OFF upon a tumble of an electric stove when a main body is directly tumbled and prevent the stove from being tumbled when a person's foot or the like is caught by a power cord by a construction wherein a detachable plug is provided at a connecting part of the power cord on the side of the stove, a receptacle for the plug is provided movably in the main body, and movement of the receptacle is restricted by a pushing-up force exerted through a push rod from a floor surface. CONSTITUTION:An intermediate plug 17 of a power cord 15 on the side of a stove is provided at the tip thereof with a magnetic body 18, which is brought into close contact with a metallic piece 21 provided at the center of a receptacle 20 in a main body. The receptacle 20 has a construction wherein one end of a leaf spring 25 movable in the inserting direction of the plug 17 is pressed against a back surface of the receptacle 20, whereas the other end receives a pushing-up force from a push rod 29 supported by a bottom plate 28 of a stand 14. Thus, the leaf spring 25 presses the receptacle 20, against the force of a tension spring 24 for the receptacle 20. When a person's foot is caught by the power cord 15 by mistake, the main body is not tumbled, and only the plug 17 is disengaged from the stand 14. When the main body is directly tumbled accidentally, the push rod 29 loses the pushing-up force, so that the receptacle 20 is retracted by the tensile force of the spring 24, and a feeder terminal 19 and a receiving terminal 22 are separated from each other, thereby stopping power supply.

Title: Optical semiconductor logic element
Inventor: KOMAZAKI IWAO
IPC: G02F3/00
Filed: 1993-08-30
Abstract: PURPOSE:To have tandem type semiconductor lasers turned on by direct input of a light pulse from outside or by amplified light or to change its output so as to stabilize the lasers by adopting the constitution to make switching and logic operation by means for implanting the light within a specific range to the oscillation wavelength of an optical bistable element. CONSTITUTION:This logic element is the optical bistable element consisting of the semiconductor laser controlled in basic mode. The electrodes of a gain region LD1 and absorption region LD2 are electrically separated. The light within the range of +5 to -10nm of the oscillation wavelength of the bistable element is implanted into the waveguide region right under the separating part from a direction parallel with the coupling surface of the lasers in a direction orthogonal with a resonator direction, by which the switching and logic operation are executed. Namely, the interference with the laser beams is weak in case of the wavelengths in the range from +5 to -10nm of the oscillation wavelength of the bistable element. The mode is thus stabilized unless the resonator length is made as short as possible even if the resonator mode of the lasers fluctuate at the coupling point.

Abstract: PURPOSE:To correct the nonlinearity of response characteristics of an infrared detector and to reduce a measurement error by providing an auxiliary infrared- ray source which outputs continuous infrared light for compensating variation in the quantity of background infrared light incident on an infrared sensor. CONSTITUTION:An infrared-ray semiconductor laser light source 10 is provided between a gas cell 3 to be measured and the infrared sensor 4 and laser beam A from the semiconductor laser beam source 1 and laser beam B from a light source 10 are multiplexed by a beam splitter 11 and made incident on the sensor 4. The beam A is projected at intermittent timing including a laser beam interruption period T, wherein the beam A is not incident on the sensor 4 and the background light and beam B are multiplexed and incident, so that the resistance value (output signal) of the sensor 4 varies with the quantity PB of the background light. This resistance value is measured by a measuring circuit 12 and the driving current of the light source 10 is controlled by a control circuit 13 so that the resistance value in the period T becomes constant. Thus, the variation in the quantity PB of light with environmental temperature is compensated and the quantity of the output signal of the sensor 4 becomes constant.
