Title: Fire origin sensor
Inventor: NAKAMURA MASAYUKI
IPC: H04N7/18
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To shorten a time to detect the origin of a fire with an infrared sensor and also prevent fire origin position detection precision from deteriorating by turning the body of equipment within the angle of visibility, that corresponds to a 1st angle at which the origin of a fire is detected, almost at every 2nd angle when the origin of a fire is detected. SOLUTION: The body of equipment 10 has a window 11, and infrared light from the origin of a fire that occurs in a supervisory area is guided into an infrared sensor through the window 11. A cover 20 has a slit 21, the width of the slit 21 is set narrower than the window 11, and infrared light from the origin of a fire that occurs in a supervisory area is guided into an infrared sensor through the slit 21. A turning controlling means normally turns the body 10 at the angle of visibility of the window 11, e.g. every thirty degrees gradually, i.e., it supervises the origin of a fire at every thirty degrees. When the origin of a fire is detected, the turning means is controlled to turn the body 10 within the angle of visibility of thirty degrees at which the origin of the fire is detected at the angle of visibility of the slit 21, e.g. every seven, five degrees gradually.

Abstract: PURPOSE:To detect the quality of a recording head or a reproducing head by judging the state of the head by means of plural combinations used for the recording head and the reproducing head. CONSTITUTION:A recording/reproducing means control circuit 2, a reproduced signal detecting circuit 3, and a discriminating circuit 4 constitute a device.

Title: Surface light source device
Inventor: TAKANO KOREI
IPC: F21V8/00
Filed: 1995-03-31
Abstract: PURPOSE: To make the luminance distribution of light from the emitting surface of a light transmission body uniform and to prevent the lowering of light quantity in the vicinity of a side surface by constituting a reflection surface so that a central part may be a diffusion and reflection surface and a part except the central part may be a regular reflection surface having high reflectance. CONSTITUTION: A reflection sheet 12 consisting of material having the high reflectance such as silver or aluminum is stuck to the inner surface 11a of a lamp holder 11 in such a shape that the central part 12a thereof is cut away. A part to which the sheet 12 is stuck has the high reflectance and the white inner surface 11a of the lamp holder 11 appears at the part where the sheet 12 is cut away. Therefore, the light at the part of the sheet 12 out of the light reaching the inner surface of the lamp holder 11 out of the light emitted from a lamp 1 is regularly reflected, while the light at the part where the sheet 12 is cut away is diffused and reflected.  Thus, the light reflected by the white surface reaches also a part directionally near to the electrode part 1a of a discharge tube 1, incident light from the incident end face of the light transmission body positioned in the vicinity of the part is prevented from being reduced suddenly, and the surface light source having uniform luminance is obtained.

Title: Blended membrane of porous polysulfone
Inventor: UDA TORU
IPC: B01D71/68
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To manufacture a porous membrane with a high performance of separating a liquid to be treated in a simple manner by mixing a polysulfone- based resin and a polyamide resin at respectively specified ratios. SOLUTION: About 55-95 wt.% polysulfone-based resin and about 45-5 wt.% polyamide-imide resin are mixed to form a porous polysulfone-based blended membrane. In this case, when the content ratio of the polyamide-imide resin is low, the improvement of the hydrophilic and the water permeation performance of a porous membrane is insufficient and when the content ratio is high, the surface of the porous membrane is fine, so that the water permeation performance is rather deteriorated. The membrane forming resin components used at the described ratios are prepared as a membrane forming stock solution obtained by dissolving the components in a aprotic polar solvent such as a dimethylformamide so that the sum of both components is equivalent to the concentration of about 15-35 wt.%. After that, the stock solution is formed into a flat membrane or a hollow fiber membrane by a routine wetting or a routine wetting/drying process, and the membrane is coagulated in a coagulating bath to be formed as the porous membrane.

IPC: F16B2/06
Filed: 1995-03-29
Abstract: PURPOSE: To prevent a connector and a clamp from contacting with the body, and quickly inject and discharge liquid by integrally joining the connector and the clamp of a connector clamp. CONSTITUTION: A connector clamp 1 is formed by using a connector part 2 and a clamp part 3 as a main constitutive part. One end of the clamp part 3 is intergally joined to the outer periphery of a midway part of the connector part 2. The clamp part 3 is formed in a roundish cylinder shape, and an outside diameter is made substantially in the same with the connector part 2. Therefore, fingers can easily hitch on a roller 4, and an extension tube can be smoothly opened and closed. Even if the connector clamp 1 contacts with the body, since it is roundish, an unpleasant contact feeling is prevented from being given to a patient. A chance of contacting with the abdominal region can be reduced by this integration.

Title: Signal detecting device
Inventor: KATO YOICHI
IPC: H02P9/02
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To provide a signal detecting device capable of removing small disturbances, offering a high control accuracy in steady state, and stabilizing a control system in transient state when used in the control system. SOLUTION: A small disturbance removing circuit 100 eliminating small disturbance signals comprises a limiter circuit 111 limiting transient signals of input signal Xin, an imperfect differential circuit 112 taking out an AC variation from the output signal of the limiter circuit 111, and a limiter circuit 113 limiting the output signal of this imperfect differential circuit 112 up to the small disturbance signal level. A subtracting circuit 130 subtracts a small disturbance signal extracted by the small disturbance removing circuit 100 from an input signal Xin and outputs an output signal Yout. As a result, the influence of the small disturbance is eliminated and the control accuracy in steady state in the control system can be enhanced.  Also, in a transient state, the operation of the small disturbance removing circuit 100 is practically prohibited by the limiter circuit for eliminating signal delay, thereby quickly stabilizing a control signal.
