Title: Ground freezing preventive method for low temperature substance storing underground tank
Inventor: KOUNO AKIRA
IPC: F17C13/10
Filed: 1978-03-13
Abstract: PURPOSE:To prevent the freezing of the ground around the tank effectively, and to secure the long-term stability of the tank body and the attached constructions by laying the heat generating pipe on the surface of the iron cage provided in the underground walls. CONSTITUTION:The water tank 9, the pump 10, and the drain 11 are provided to the underground tank 1, and the water in the tank 9 is supplied to the heat generating pipe 8 by the pump 10. By doing so, the continuous underground wall 2 is heated by the heat generating pipe 8 straying inside. Since the heat generating pipe 8 is layed, when the underground wall 2 is constructed, so that the pipe 8 contacts the iron cage 4, not only the cage is directly heated by the heat generating pipe 8 but the heat from the heat generating pipe 8 is conveyed to the iron cage 4 which can also serve as the heating source itself. Therefore, the underground wall 2 can be uniformly heated throughout the whole surface, and as the result, the freezing of the surrounding ground can be effectively prevented.

Abstract: PURPOSE: To restore the photographing operation of a camera by eliminating the occurrence information of abnormal operation stored in a non volatile memory means by specified switch operation. CONSTITUTION: A camera is provided with a camera driving controlling means 1, an electric power supplying means 2 for the controlling means 1, a non- volatile memory means 3, an abnormal operation detecting circuit 4, and a film winding back switch 5. The camera driving controlling means 1 reads out the information from the memory means 3 and judges the abnormal operation and in the case the means 1 determines that abnormal operation occurs, the means 1 stores the abnormal operation occurrence information in the non- volatile memory means 3 and inhibits photographing operation of the camera. Then, the camera driving controlling means 1 judges whether the film winding back switch 5 is operated or not and in the case the film winding back switch 5 is not operated, the means 1 eliminates the abnormal operation occurrence information stored in the non-volatile memory means 3.  Consequently, in the case of an abnormal operation happened by chance, the camera is returned to photographing operation with no need of a tool to communicate directly with the memory means 3.

Abstract: PURPOSE:To prevent a nozzle from allowing air inflow and ink run thereto as well as ink dry therein, by a method wherein a cap device comprises; an elastic body mounted on the circumferential edge thereof and in contact with a head; an air bleed hole opened/closed by a shutter, and also the adhesion of the cap device to the head is ensured by pressing again the elastic body thereto after the adhesion is completed by pressing the elastic body being deformed. CONSTITUTION:When the printing is not performed, travel of a roller 12 along with a roller guide profile rail 14 results in travel of a cap device toward a head 15, and the cap device comes into contact therewith. Simultanenously, an elastic body 2 begins deforming and continues until it comes on the front ends of elastic deformation limit rods 7, 7, thus the first step is completed. In this condition, the airtightness between the head and the cap is ensured, and an air bleed hole 3 is opened, which does not induce pressure increase. The presence of the limit rods prevents the space in the cap to be further compressed. The cap still presses the head, and a slide shutter 4 at the tip end of a push rod 5 moves by being forced by a compression spring 8 to close the air bleed hole 3.

Title: Apparatus for chucking semiconductor wafer
Inventor: MURAKAMI SHIGEYUKI
IPC: H01L21/68
Filed: 1986-02-13
Abstract: PURPOSE:To enable a semiconductor wafer to be held by a sufficient suction force of a vacuum even if the semiconductor wafer is warped or defects such as cracks or the like are produced on the wafer carrying surface of a chucking apparatus for carrying the wafer, by providing vacuum suction paths opened in projected regions of the wafer carrying surface surrounded by grooves such that those section paths give a direct suction effect. CONSTITUTION:Second vacuum suction paths 6 are provided within a wafer carrying section 2. When a vacuum is drawn, insides of recessed grooves 4 and 5 are wholly evacuated through a suction path 3 and a semiconductor wafer 10 is sucked by the vacuum present in the spaces of the grooves. In addition thereto, said vacuum suction paths 6 are provided so as to independently act on respective projected regions of the surface of the wafer carrying section 2 so that the suction effect as a whole is enhanced by that much. Further, the suction of the suction paths 6 functions sufficiently, even if the vacuum within the grooves 4 and 5 is nullified by warpage of the semiconductor wafer 10 for example. Accordingly, even if a motor 13 is driven with the wafer 10 sucked insufficiently by means of the vacuum in the grooves 5 and 6 and a chucking apparatus is rotated rapidly, the semiconductor wafer 10 can be effectively prevented from being deviated from the center of slipping out of the wafer carrying section 2.

Abstract: PROBLEM TO BE SOLVED: To indicate a place name which a user arrives at in near future by providing a storage means, etc., for storing an information on place name in correspondence with a position information. SOLUTION: A CD-ROM 51 (storage means) stores an information on place name in correspondence with a position information. When a position data is sent from a GPS block 2 during running, a CPU 10 calls a map information and route information around the present position from the CR-ROM 51 through a peripheral circuit gate array (G/A) 11 and a CD block 5. Then the position information on the position a specified distance ahead of the present position is detected on the basis of the information relating to the present position and the directional information, and the information of place name corresponding to the position informations is read out and indicated. Thus the place name a specified distance ahead of the present position, that is, a place name which a user arrives at soon, can be recognized visually by the screen of a monitor 6.  Therefore, it can be checked without complicated operation what direction to move or whether or not the route navigation is correct, and so on.

Abstract: PURPOSE:To maintain sufficient gettering effect and to minimize the warpage of a semiconductor substrate after laser light is irradiated by disposing a mask having a plurality of holes in a laser light optical passage to divide the light into a plurality of spotlike light beams and irradiating the rear surface of the substrate therewith. CONSTITUTION:Laser light oscillated by an excimer laser 1 is divided by a mask 2 into a plurality of spotlike light beams, then throttled by a lens 3 to an optical intensity density sufficient to damage a semiconductor substrate 5, and then irradiated on the rear surface of the substrate 5. A plurality of spotlike damages corresponding to the shape of the radiated light are formed on the rear surface of the substrate 5. Thus, since the damage area of the whole substrate 5 can be reduced, the flatness of the substrate can be held preferably even after the laser light is irradiated, and next step can be performed without fail by the irradiated substrate 5.
