IPC: G01N27/20
Filed: 1988-11-21
Abstract: PURPOSE:To detect a pinhole of a plastic film of the inside surface of a container by injecting a conductive liquid into a packaging container, and also, immersing the packaging container into the conductive liquid, and detecting a decrease of an electric resistance between the conductive liquids of the inside and the outside of the container.

Subsequently, one electrode and the other are inserted through an electric conduction meter 6 into the packaging container and the external conductive liquid, respectively. In this state, when a pinhole 5 does not exist, the conduction meter 6 shows the infinity of an electric resistance value and the needle does not deflect, but when the pinhole 5 exists, the electric resistance value drops and the needle comes to indicate almost '0'. In such a way, a pinhole of a plastic film of the inside surface of the container can be detected in a short time by a simple method.

Title: Photoelectric automatically flashing device
Inventor: HIGASHIYA KAZUNORI
IPC: G05B11/16
Filed: 1987-11-20
Abstract: PURPOSE:To reduce power consumption in the case of using two winding latch relay with no auxiliary contact by taking an on-off signal of a control circuit as one pulse signal through opening/closing of contacts except a main contact of that relay. CONSTITUTION:In the case the there becomes bright in the surroundings, the resistance value of CdS1 is lowered and an input voltage is lowered from a comparator CP1 to a comparator CP4 in order, thereby an output being reversed. Only the output from comparators CP2, CP4 are received to RS latches La1 to La3. Thus, the output from a NAND circuit NAND1 is H level and the output form a NAND circuit NAND2 is also H level. Accordingly, a transistor Q2 is conducted with the output of the NAND circuit NAND2 so as to apply an exciting current to an exciting coil L2 and thereby a contact r1 is opened for putting-out a lighting load L. As relay Ry1 is driven, a contact r2 is opened. Thus, the output from an inverter I1 is lowered to L level so that the transistor Q2 is non-conducted resulting in cut-off of the exciting current to the exciting coil L2.

Title: Steel for machine structural use excellent in straightness after cold drawing
Inventor: YANAGIYA TOSHIO
IPC: C22C38/00
Filed: 1990-10-31
Abstract: PURPOSE:To improve the straightness of a steel after cold drawing and straightening and to eliminate its restraightening and terstraightening by adding Al and Ti to a steel for structural use having a specified compsn. and reducing [N] as solid soln. CONSTITUTION:This steel for machine structural use has a compsn. contg., by weight, 0.1 to 0.5% C, <=1.0% Si, <=2.0% Mn, 0.03 to 0.06% SolAl and/or 0.015 to 0.050% Ti, in which total N is regulated to <=0.015 and [N] as solid soln. is regulated to <=0.002 and the balance Fe. At the time of manufacturing parts by machining, [N] as solid soln. is regulated because the higher the bending residual amt. of wire rod recoiled from a coil after cold drawing and straightening before machining the higher its content. As for Al, it is required by the lower limit or above because it fixes N as AlN and regulates [N] as solid soln. to the above value, but in the case of more than the upper limit, it damages the cleanliness of the steel. As for N, it is regulated to prevent the formation of abundant AlN and the deterioration in its fatigue strength thereby. Furthermore, Pb is preferably regulated to <=0.0050.

Filed: 1992-11-04
Abstract: PURPOSE:To provide an in-pipe ice making unit and an in-pipe ice making method with high efficiency at a relatively high temperature where metal is prevented from being corroded. CONSTITUTION:This unit is adapted such that a plurality of thin tubes 2 are disposed in a shell 1, and the tubes 2 are fully filled with heat storage water to make sharbet like ice. A low concentration hygroscopic aqueous solution is used as the heat storage water, and a nonfreezing fluid or a refrigerant is directed to pass through the outside of the tube 2. A nonfreezing fluid at a freezing temperature or lower of the heat storage water kept in a static state or a refrigerant at an evaporation temperature is directed to pass through the outside of the tube 2 to form sharbet like ice. With use of as the heat storage water the low concentration hygroscopic aqueous solution having a property less than a freezing point or lower in response to strong osmosis (hydration) and concentration, an acetic acid compound produced following the production of the ice penetrates and is raised in its concentration and hence lowers the freezing point, so that the sharbet like ice can be made in the hygroscopic aqueous solution not frozen. The low concentration hygroscopic aqueous solution has its freezing point at about -1 deg.C, so that a high temperature freezing solution or refrigerant is made useable for improved efficiency compared with prior art examples having their freezing point at about -5 deg.C.
