Patent JP-H07260706-A (JP)
Title: Flaw detector
Inventor: ITO MASAHIRO
IPC: B65B57/02
Filed: 1994-03-23
Abstract: PURPOSE:To enable detection of an indentation of a thin plate or a bubble therein by applying a light to the surface of a sheet-shaped object of inspection from a direction at a certain angle to the surface and by detecting the light transmitted through the object and deflected to a prescribed angular direction. CONSTITUTION:A light of a length being equal practically to the width of a resin sheet 11 is applied perpendicularly practically to the surface of the sheet from a light applying device 12. A transmitted light is detected by TV cameras 13A to 13C. A light L2 outputted from a light applying device 14 is applied at a prescribed angle to the axis perpendicular to the resin sheet 11, in superposition on the light applied from the device 12. When there is a foreign substance in the sheet 11, the transmittance of the light applied from the device 12 lowers and outputs of the cameras 13A to 13C lower. However, the irradiation light L2 has no effect on the outputs of the cameras, since it has directivity. When the surface of the sheet 11 has an indentation, the quantity of the light inputted to the cameras 13A to 13C from the device 12 is not varied, but the light L2 is separated in various directions by the part of the indentation, part of it entering the cameras 13A to 13C and the outputs of the cameras being increased. Therefore the existence of the indentation can be detected.

Title: Mold molding method
Inventor: UNOSAKI TSUNETO
IPC: B22C15/24
Filed: 1979-04-24
Abstract: PURPOSE:To enable the obtaining of the mold of good mold surfaces by subsequently charging the facing sand and backing sand of the specified grain sizes into the spacing thence supplying compressed air for the specified time from above the molding sand and letting the same pass through the molding sand. CONSTITUTION:A molding flask 8 is placed on top of a pattern plate 2 and facing sand 10 having been made to the sizes larger than the vent holes 4, 5, 6 of vent plugs is charged into the spacing thus formed to the extent that the pattern part 3 is concealed. Following to this, backing sand 11 is charged at the specified amount to the top surface of this facing sand 10. Thence, a hermetic cover 12 is placed airtightly on the top of the molding flask 8. When compressed air is supplied through this hermetic cap 12, this compressed air flows into the molding flask 8 through a feed hole 13 and passes in the backing sand 11 and facing sand 10, thereby causing the facing sand 10 to deposit densely on the surface of the pattern plate 1. Only the air is then exhausted to the outside through exhaust holes 4, 5, 6. Thence, the compressed air is stopped and the hermetic cover 12 is removed. The molding sand is next squeezed by the compression plate not illustrated.

Title: Multiple-room cooler-heater
Inventor: KURACHI MASAO
IPC: F24F11/02
Filed: 1988-03-04
Abstract: PURPOSE:To perform a comfortable air conditioning with little variation in room temperature, by providing a heat source side refrigerant cycle, a use-side refrigerant cycle, a pressure detector for detecting the pressure of a refrigerant in the use-side refrigerant cycle, and a controller for controlling the capacity of the heat source side refrigerant cycle according to the pressure detected by the detector. CONSTITUTION:A pressure detector 31 detects the pressure of a refrigerant on the use side, and an exterior unit (f) is controlled in capacity (for example, the rotational frequency of a compressor is controlled) by a controller 32 according to the pressure detected by the detector 31. For example, when the temperature in a room to be air-conditioned is raised or the number of room units operated is increased in a cooling operation, a load on a use-side refrigerant cycle is increased with the result of a rise in the refrigerant pressure. At this time, a detection signal from the pressure detector 31 is varied, and the controller 32 is operated to enhance the capacity of a heat source side refrigerant cycle through, for example, raising the rotational frequency of the compressor 11. Therefore, no delay is generated in responding to a rapid load variation, so that slight variations in room temperature as well as enhanced comfortableness are produced; there is not possibility of the operation being stopped due to a rise in a higher pressure because of a delay in response under a low heating load.

Title: Spectrum analyzer
Inventor: HIROSE MASAAKI
IPC: G01R23/173
Filed: 1979-04-28
Abstract: PURPOSE: To stably and accurately observe the narrow band spectrum by a spectrum analyzer by inserting a sample-holding circuit thereinto to correct only the frequency variation of a voltage controlled variable local oscillator and stabilizing the local oscillator.  
     CONSTITUTION: When switches S1, S2 are set as shown, a local oscillator Of is controlled by the output of a lamp voltage generator R to sweep in narrow frequency band. Since the output frequency of the local oscillator Ov retains substantially predetermined constant value determined by a voltage source V, the narrow higher and lower frequency range spectrum is presented in an oscillograph B around the desired frequency determined by the adjustment of the voltage source V as a center. In this case, the output of a frequency discriminator Df is applied through a sample-holding circuit H and amplifiers A, E to a voltage controlled variable frequency local oscillator Ov. Therefore, the frequency variation is eliminated to stably produce a predetermined constant local oscillating frequency therefrom. Since the output of the discriminator Df is intermittently extracted and retained in the circuit H to control the local oscillator Ov, the narrow band spectrum can be accurately observed.

Abstract: PROBLEM TO BE SOLVED: To extremely reduce cost increase and work man-hour increase by forming an optical reflector and an electronic wave reflector that is effective to an electronic wave in a frequency range of 50-100 GHz in a signle unit. SOLUTION: An optical reflector 1 and an electronic wave reflector 2 that is effective to an electronic wave in a frequency range of 50-100 GHz are formed in one unit and are mounted to a frame body 3. The reflector 2 is fabricated by a resin material and a surface treatment is made to a concave electronic wave reflection surface by metal. Light that is applied to the reflector 1 is directly reflected on the surface and at the same time incidence light is refracted by a prism that is formed on a rear surface and is emitted as reflection light. On the other hand, an electronic wave that is emitted from a radar device passes through the reflector 1, is reflected repeatedly by the reflector 2, passes through the reflector 1 again, and is reflected toward an emission side.  A reflection wave from a vehicle with the reflector 2 is reflected with a large value over a wide range as compared with a reflection wave from a vehicle without any reflector 2.

Title: Ozone water making apparatus
Inventor: SUZUKI ISAO
IPC: C01B13/10
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To provide an ozone water making apparatus certainly separating ozone included in ozone water. SOLUTION: Ozone impossible to dissolve is included in ozone water having ozone supplied from an ozone generator 24 dissolved to be mixed therewith in a bubble like state. Ozone in this bubble like state is finely divided by a mixer 18 to be still more enhanced in dissolving ratio. The ozone water flowing in an ozone water tank 8 through the mixer 18 flows upwardly by the weir part 17 formed on a bottom part 3 upwardly at the almost intermediate part between an inflow port 4 and an outflow port 5 and gets over the weir part 17 to flow downwardly to go toward the outflow port 5. Ozone in a bubble like state is carried to the upper part of the ozone water tank 8 by ascending flow to be separated from ozone water and stored in the vicinity of the ceiling part 6 of the ozone water tank 8.  Since ozone in a bubble like state rises to the vicinity of the surface of ozone water by buoyancy, it is not drawn in the flow getting over the weir part 17 to be changed downwardly from upward flow.
