Title: Dehumidification device
Inventor: MATSUOKA AKIRA
IPC: B01D53/26
Filed: 1988-05-26
Abstract: PURPOSE:To regenerate a moisture-absorbing material in quick response to its performance, and simplify and make compact a device by measuring a resistance value between a plurality of conductors arranged in the moisture-absorbing material to directly detect its moisture content and regenerating the moisture-absorbing material in accordance with the detected moisture content. CONSTITUTION:Conductive pins 31 are inserted at a specified interval in a moisture- absorbing material 1 consisting of hygroscopic filler such as calcium chloride which is internally added and held in the microvoids of a porous material. If the moisture level of the front (the side facing the room) is high, the moisture taken in the moisture- absorbing material 1 from the front moves to the back and is released from the back of the moisture-absorbing material 1 as a vapor following the heat generation of a heat-generating element 2. At that time, if a resistance value between the conductive pins 31 is measured, and the resistance value reaches less than a specified value due to the increase in a moisture content of the moisture-absorbing material 1, a detection means detects this and a control means controls the energization to the heat-generating element 2. The evaporated vapor attaches to the internal surface of an extended section 51 of a covering member 5 to cause a condensation, and is recovered to a water tray 6 below.

Title: Method for controlling automatic pouring by sectorial ladle
Inventor: ITOU SHIGERU
IPC: B22D41/04
Filed: 1983-07-15
Abstract: PURPOSE:To enable stable and automatic pouring by supplying a molten metal from a ladle having a sectorial shape to the molten metal inflow port having approximately an inverted conical shape of a casting mold, measuring the transverse size of the top surface of the molten metal in the inflow port and controlling automatically the supply rate of the molten metal. CONSTITUTION:A ladle 1 having a sectorial shape 1 is tilted toward R pivoting at a pouring port 3 thereof to pour a molten metal to the molten metal inflow port 6 of a casting mold 4. The molten metal is detected with a detector 10. The tilting of the ladle 1 is stopped when the ladle 1 is tilted to the angle at which the molten metal of the amt. larger than the required amt. can be tapped upon lapse of the set time. The molten metal flows out via the port 3 to the port 6. The transverse sizes (a), (b) at the top surface of the molten metal in the port 6 are detected and measured with a detector 11. If the actually measured value is larger than the preset transverse size of a specified range, the ladle 1 is tilted backward by the set time to decrease the outflow rate of the molten metal and when the value is smaller than said size, the ladle is tilted by the set time to increase the outflow rate. Such operation is repeated to corect the outflow rate so that the outflow rate of the molten metal is controlled to a specified range.

Title: Centrifugal impeller
Inventor: UEDA SHINJIROU
IPC: F04D29/28
Filed: 1979-10-11
Abstract: PURPOSE: To improve the efficiency of an impeller by maintaining the relative speed distribution in an impeller in a good form, in a centrifugal impeller having a low specific speed and a small exit angle of the vane wheel.  
     CONSTITUTION: The shape of the meridian surface of an impeller is widened toward end in the vicinity of te exit of the impeller. Namely, in the shape of the meridian surface, a core plate 2 is formed into rectilinear form and the side plate 3 is formed into circular arc. As a result of this, the width b 2  of the exit is larger than the width b m  of the intermediate part of the flow pasage. Due to the shape of the meridian surface flow passage, the sectional area of the flow passage at the intermediate part of the flow passage reduces, and the speed on the meridian surface increases. On the other hand, in the vicinity of the exit, the sectional area increases relatively, and the speed on the meridian surface reduces. Accordingly, the relative speed distribution becomes desirable in which the speed reduces continuously and monotonously from the inlet of the impeller to the exit, and the minimum value is not form midway in the average speed.

Filed: 1989-05-25
Abstract: PURPOSE:To improve engine control precision by setting the correction quantity corresponding to the leakage air quantity based on the air-fuel ratio correction value and the intake air flow corresponding to it when an air leakage self- diagnostic device judges air leakage. CONSTITUTION:When the correction rate by the air-fuel ratio correction ratio set by an air-fuel ratio correction value setting means based on the output of an air-fuel ratio detecting means is made larger in the operation region where the suction air flow is less, an air leakage judging means judges it as the air leakage of a suction system. When the occurrence of the air leakage is judged, the correction quantity of the suction air flow corresponding to the leakage air quantity is set by a leakage correction quantity setting means based on the suction air flow corresponding to it, and the suction air flow detected by a suction air flow detecting means is corrected via a suction air quantity learning correcting means. The setting precision of engine control quantities such as the fuel feed quantity and the ignition timing can be improved.

Title: Displacement measuring instrument for buffer
Inventor: YAMAGUCHI HIDEMI
IPC: G01B21/00
Filed: 1988-05-30
Abstract: PURPOSE:To measure a displacement of a buffer corresponding to the displacement amount of an article easily and accurately for everyone by reading out the displacement amount of a moving piston when the moving piston is held in a maximum displacing condition, with a scale indicated on a cylinder. CONSTITUTION:When a shock is given to a case 1, the buffer 2 is deviated and the article 3 to be protected is also displaced against the case 1, thereby moving piston 1A is pushed into the cylinder 11B and a clay 12 in the cylinder 11B is compressed. At this time, an indicating needle 15 on the piston 11A is also shifted to the pushed direction. Thus, after the deviation of the buffer 2 is made to be the maximum limit, the buffer 2 is going to return to the initial state with its own repulsive force, but the return of the piston 11A is forcedly regulated by a reaction stopper 13, thereby the piston 11A is made to stop and held at the maximum deviated position of the buffer 2. So, the displacement amount of the article 3 against the case 1, i.e. the displacement of the buffer 2 can be accurately measured for everyone easily by means of reading the value indicated by the indicating needle 15 on the scale 16 at this time.

Title: Thermosensitive sheetlike exothermic body and manufacture thereof
Inventor: KAMIKAWA MICHIHARU
IPC: H05B3/20
Filed: 1990-05-21
Abstract: PURPOSE:To improve durability and thermal endurance of adhesive strength between a metal foil and thermosensitive resin by gluing the metal foil, through a thermally melting adhesion, to a thermosensitive resin film in which an equivalently 5 to 10 part of lead stabilizer is added, after forming a particular adhesive thin film layer on the metal foil in advance. CONSTITUTION:An adhesive thin film layer 8 made by adding equivalently 1 to 8 part of epoxy resin to an adhesive resin including vinyl-chloride/vinyl acetate copolymer resin as its main component is formed on a metal foil in advance, and thereafter metal foils 1-3 are glued, through thermally melting adhesion, to a thermal resin film 7 prepared by adding equivalently 5 to 10 part of lead stabilizer. As a dehydrochloric acid reaction, which is thermal decomposition of a thermal adhesive resin 8 comprising vinyl acetate can not progress because of a stabilizing action of epoxy resin hydrochloric acid is captured so as to stop progress of decomposition no hardening of the adhesive resin takes place and the adhesive strength is not subjected to secular change during hot processing. Accordingly the durability and the thermal endurance are improved because of no secular change of the adhesive strength between the thermosensitive resin film 7 and the metal foils 103.

Title: Position detector for moving object
Inventor: MIYABAYASHI KAZUHIRO
IPC: G01B21/00
Filed: 1988-05-27
Abstract: PURPOSE:To cause a moving object to correspond to various conditions flexibly and to attain the position detection by selecting or operating various detecting signals obtained from plural sensors with a conditions setting means and operating a control device with the output signal. CONSTITUTION:A timing generating means 5 sends a detecting signal from first and second sensors 1 and 2 with respective types of timing such as (a)-(h) to a conditions setting means 6 and a conditions setting means 6 selects one signal or above sent, operates and sends it to a control device 7. When conditions are set so as to select timings (b) and (c), for an automobile 3 to advance in a direction C, in a moment when the peak part arrives at a detecting position A, a timing (b) occurs, the control device 7 functions, and the video of a television camera 8 is recorded to a video recorder 9. For an automobile 4 to advance in a direction D, in a moment when the rear part is away from the detecting position A, a timing (e) occurs and in the same way as the earlier case, the video is recorded. Thus, the position detection can be performed corresponding to the various conditions flexibly.

Title: Evaporating type burner
Inventor: KASUKAWA NOBUYUKI
IPC: F23D11/40
Filed: 1982-07-26
Abstract: PURPOSE:To prevent production of tar and to enable the fuel to be sufficiently evaporated during combustion operation even if energization to a heater for evaporation is disconnected, by using ceramic such as alumina in an evaporating tube. CONSTITUTION:The fuel from an oil feed pipe 7 is atomized by a shake-off plate 9 and a diffusion plate 11, and collides with an evaporating surface 4 of an evaporating tube 1 in which ceramic such as alumina is used. Thus, the evaporating surface 4 of the evaporating cylinder 4 previously heated by a heater 5 for evaporation evaporates the atomized fuel which flies for collision therewith. The evaporated fuel flows in the direction of a second evaporating chamber 13 along the evaporating surface of the evaporating cylinder 1, and its flow is regulated by the passage of it through a flow straightening hole 14 in an flow straightening plate 12 to reach a flame port 3. The evaporated gas of the fuel reaching the flame port 3 is fired in the flame port 3 to form flame. This suppresses production of tar and enables the fuel to be sufficiently evaporated during combustion operation even if energization to the heater for evaporation is disconnected.
