IPC: A62D1/00
Filed: 1989-12-18
Abstract: PURPOSE:To secure the visual field at least in the vicinity of a refugee in the case the room is filled with smoke caused by a fire, etc., by constituting the smoke extinguisher of a portable pressure vessel having a spray nozzle, and high pressure gas and water filled in the pressure vessel concerned, and adding a surface active agent of specific PPM to this water. CONSTITUTION:The portable smoke extinguisher is provided with a portable pressure vessel 1 having a spray nozzle 3, and the inside of the pressure vessel 1 is filled with a gaseous CO2 liquid (not shown in the figure) of high pressure, and water to which a cationic surface active agent of 0.3-3000PPM is added. By pressing a push-button 2, a valve (not shown in the figure) provided on a root part 4 of a spray nozzle 3 is opened, and water in the pressure vessel 1 is sprayed from the nozzle 3. In this case, the cationic surface active agent has an excellent smoke extinguishing effect. It is because smoke particles are generally electrified to negative, therefore, they attract mutually the cationic surface active agent charged to positive and an attraction effect is improved.

Title: Power supply
Inventor: TAKAHAMA MASANOBU
IPC: H02J1/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent the flow of over-current into a switching element, when an input voltage rises abruptly. SOLUTION: When momentary interrupt of an input AC voltage occurs, a comparison means 6 does not generated pulse during such period, because a voltage is not supplied from a rectifying circuit 106 to the comparing means 6. Therefore, a pulse detecting circuit 8 is unable to detect the pulse in this case and outputs a cut-off signal. The pulse detecting circuit 8 delays this cut-off signal for about 20 msec, before it provides the output. Therefore, even if momentary interrupt is recovered, the cut-off signal is output for about 20 msec after such a recovery. When the cut-off signal is input from the pulse detecting circuit 8, a drive pulse generating circuit 125 stops the generation of a drive pulse to turn off a switching element 118.

Filed: 1990-11-30
Abstract: PURPOSE:To maintain a proper fuel pressure and realize the operation of burners by increasing or decreasing their number in operation by providing an action which absorbs the fuel pressure variation at the time of increasing or decreasing burner in operation in the direction to a standard fuel pressure. CONSTITUTION:The fuel pressure correction proportion 21 that corresponds to the number of ignited burners is given by the ratio of a standard fuel pressure required to maintain the most suitable state of combustion at respective number of the ignited burners to the actual fuel pressure. Function generators 22, 23 transmit a correction proportion for the instruction to increase or decrease burner with respective fuel pressure correction proportions 21 as an index. Multipliers 24 and 25 add correction proportion with the fuel pressure to the burner number deviation signals in the direction of increasing or decreasing burner that are transmitted from comparators 24 and 25 as an index. Correction circuits 21-25 set correction proportion with the ratio of proper standard fuel pressure corresponding to the number of ignited burners to actual fuel pressure as an index so as to absorb the variation in fuel pressure at the time of increasing or decreasing burner in the direction to a standard fuel pressure. The transmission of an instruction to increase or decrease burner is stopped when the fuel pressure is much out of the standard fuel pressure and it is maintained in a proper range.

Title: Analyzing system for contact stress
Inventor: EZAWA YOSHITAKA
IPC: G06F19/00
Filed: 1990-11-30
Abstract: PURPOSE:To analyze the contact stress without re-inserting an element even when the contact face slides relatively large by sequentially switching an element which has zero rigidity and an element which has the rigidity not equal to zero, depending on the relative positional relationship of the contact face. CONSTITUTION:A contact element is a virtual five-node quadrangular pyramid so defined that the bottom faces 1, 2, 3, 4 are on one contact surface 8 and the apex 5 is at the confronting face 7. This element represents the contact condition between the foot of perpendicular 6 from the apex 5 to the bottom face and, the apex 5. What is of physical significance is when the foot of perpendicular 6 is within the bottom face. In the case where the five-node contact element is applied to (a), the rigidity of the elements 2, 11, 12, 3, 5 and 9, 1, 4, 10, 5 is set to be zero. When the apex 5 is moved because of the deformation as in the case (b), the elements 9, 1, 4, 10 are changed to be effective, and the rigidity of the elements 1, 2, 3, 4, 5 is turned to zero. Accordingly, even when a large relative movement occurs, it becomes possible to analyze the contact stress without re-dividing the element.

Title: Bipolar transistor
Inventor: IMAMURA KENICHI
IPC: H01L29/08
Filed: 1993-12-27
Abstract: PURPOSE:To facilitate the reduction of the thickness of a base layer by a method wherein, instead of providing a base electrode, a second emitter electrode is formed on an emitter layer in addition to a first emitter electrode and charge accumulated in the base layer is sucked up by the second emitter electrode through a depletion layer between the base layer and the emitter layer. CONSTITUTION:A first emitter electrode 26a1 and a second emitter electrode 26a2 are formed respectively on a first emitter contact layer 261 and a second emitter contact 262 which are formed on an emitter layer 25 with a spacing. The emitter layer 25 and a base layer 24 of which a second emitter is composed are doped so as to have impurity concentrations which facilitate the tunneling of the charge of the base layer 24 into the second emitter electrode 26a2 through a depletion layer. In this process, the second emitter electrode 26a2 functions like a base electrode, so that the base electrode is not necessary and the base layer 24 thickness can be redused. With this constitution, excellent radio frequency characteristics can be obtained.

Abstract: PURPOSE:To heal and prevent a disease such as waste pains by arranging an air cushion in which first, second and third air bags are arranged adjacent to one another and a air supply source to allow the supplying of the air bags with air separately to correct ossification of a joint. CONSTITUTION:A user 27 lies on his back on an air cushion 22. Left and right hips are placed on first and second air bags 25A and 25B and the third air bag 25C gets under the thereof. When an air supply source 23 is operated, the air bags 25A, 25B and 25C are supplied with air sequentially. In response to expansion or contraction of the air bags 25a and 25B, left and right iliac bones 4 move with respect to a sacred bone 3 in a direction of the arrow A to expand mobile areas of left and right secred- iliac joints 10. In response to the expansion or contraction of the air bag 25C, a waist vertebra 8 moves with respect to the sacred bone to expand the mobile area of a waist-sacred joint 9. With the mobile areas of the waist-sacred joint 9 and secred-iliac joint 10 of the pelvis 1 being expanded, ossification of the joints 9 and 10 can be corrected. This allows even a person maintaining a forward bent attitude for a long time to accomplish a normal walking stretching his backbone line with a step taken wide thereby enabling the realization of two-step walking with a better balance.

Filed: 1988-12-26
Abstract: PURPOSE:To withdraw structural steels safely and surely with small force by inserting the structural steels, adherently covered at their surfaces with sulphur mortar sprayed thereon, into cement material that is to harden later, and by detaching the structural steels from a retaining wall by heating the mortar for melting the same. CONSTITUTION:At construction of a continuous retaining wall, structural steels 3, after being covered adherently at their surfaces with sulphur mortar 7 made of sulphur as its principal material, are inserted into cement material 2 that is to harden later. After performing a function as the continuous retaining wall, the sulphur mortar 7 is heated and melted by a method such as of supplying electric current to electric heating wires 5, and the structural steels 3 are pulled out thence. The sulphur mortar 7 hardens at a temperature of 110 deg.C or below becoming to have the strength same as or above the cement mortar, and softens at a temperature of 110 deg.C or above becoming liquid substance rich in fluidity. Therefore it does not do any harm to the structural steels 3 during the use and recovery of the structural steels 3 after the use of the structural steels can be easily carried out.
