Title: Cooler
Inventor: ICHIGAYA KOJI
IPC: F25D7/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a cooler which can cool down cooked food, drinking water, etc., rapidly without consuming cooling water such as city water wastefully. SOLUTION: When an upper cover 30 is put on a main body 10 to be integral therewith on the occasion of the use, a projecting part 32 of the upper cover 30 is brought into a state of being inserted into a slot 11 provided in the main body 10, and a projection of a water introducing sheet is immersed in water. The water is sucked up quickly from this portion by a capillary phenomenon and reaches the tip of a finger-shaped part. The water spreads also to a vaporizing sheet and the whole of this sheet is brought into a wet state. A matter to be cooled is placed on the upper cover 30. When a fan 20 is switched on, air flows through a longitudinal groove 13 and then through lateral grooves 14 and discharged from the right side of each lateral groove 14.  Vaporization of the water is facilitated at this time and the upper cover 30 is cooled down by that the heat of vaporization is absorbed on the occasion.

Title: Magnetic recording medium and its manufacture
Inventor: SUZUKI MASAYASU
IPC: G11B5/845
Filed: 1988-06-29
Abstract: PURPOSE:To obtain a magnetic recording medium having excellent charac- teristics against counterfeiting by inserting deciding information, which cannot be added or erased later, to a magnetic recording medium when a magnetic coating is applied. CONSTITUTION:On a substrate consisting of a non-magnetic substance, a first magnetic layer, which consists of a magnetic substance having higher coercive force than that of the ordinarily used magnetic recording material, namely, the higher coercive force than 3000 oersted, and to which discriminating magnetic information for counterfeiting prevention has been written beforehand, is provided. Further, a second magnetic layer consisting of the ordinarily used magnetic substance is laminated as the magnetic recording material. Since the first magnetic layer consists of the magnetic substance at the high coercive force, which is ordinarily used as the magnetic recording material, the magnetic recording and erasing is difficult by a generally used magnetic head or a permanent magnet excluding a period before the magnetic layer at the time of the coating is dried. Thus, the counterfeiting and unjust use are made difficult.

Title: Magnetic head
Inventor: YONEDA YOSHIRO
IPC: G11B5/127
Filed: 1986-07-07
Abstract: PURPOSE:To improve the stability and the reproduction efficiency of the reproduction output of magnetic head by forming a notch at the end part of a main magnetic pole film in the track width direction to fix the magnetic anisotropy of the main magnetic pole film. CONSTITUTION:Several notches 8 are formed to a main magnetic pole film 1 at the end part of a part held between nonmagnetic substrates 2 and 4 and in the track width direction. These cuts 8 are produced by forming a soft magnetic thin film 1 on the entire surface by a sputtering process, etc., and then removing the undesired areas by etching. As a result, a circulating magnetic domain can be reduced with a small anisotropic magnetic field Hk kept as it is. Thus it is possible to prevent deterioration of the head reproduction efficiency caused by the circulating magnetic domain.

Title: Air-conditioner
Inventor: HATTA HIROSHI
IPC: F25B1/00
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To reduce temperature change in fluid to be cooled by closing the oil-returning piping of the oil separator at the discharge side of a compressor being stopped, and by switching to an oil-returning piping for returning refrigerating machine oil to intake piping of the compressor being stopped when operation state is switched to unloader control. SOLUTION: The temperature of fluid to be cooled that is cooled by an evaporator 5 is detected by a sensor 7 and the number of compressors 1a, 1b, and 1c is controlled (unloader control). Also, solenoid valves 8a, 8b, and 8c are arranged in oil-returning pipes 6a, 6b, and 6c. Then, immediately when operation state is switched to the unloader control, the solenoid valves such as the solenoid valves 8a and 8b are closed, and the solenoid valve 8c is opened, thus preventing refrigerating machine oil from flowing into the compressor 1c being stopped, and at the same time successively returning the refrigerating machine oil to the compressors 1b and 1c via the oil-returning pipes 6b and 6a. As a result, the unbalance of the refrigerating machine oil and the adhesion and seizure of the compressors 1a-1c can be prevented.

Title: Tape reel
Inventor: SAKAI MASAHIRO

Filed: 1987-06-26
Abstract: PURPOSE:To adjust the warping of a flange due to heat contraction, etc., by setting a groove generated between an entry edge wall and a supporting wall so as to straddle over a hub and the flange, and setting a groove bottom obliquely in a direction of groove width. CONSTITUTION:The end face of the projecting stripe part of a male metallic die forming the groove 7 of a reel main body is inclined, and the tilt angle O of the end face is changed by cutting the end face of the projecting stripe part fitting to the warping of a lower flange 5, and the tilt angle O of the groove bottom 7a between the entry edge wall 4a and the supporting wall 6 of a hub hole 4 is adjusted. In other words, since the groove generated between the entry edge wall and the supporting wall straddles over the hub and the flange and the groove bottom is inclined in the direction of groove width, it is possible to correct the warping of the lower flange 5 by deforming thickness by adjusting the tilt angle of the groove bottom and utilizing heat contraction difference due to deflected thickness. In such a way, since a small amount of warping is given on the lower flange, the warping of the lower flange 5 is set within an allowable value even when a certain level of change occurs in an external temperature or filling speed, etc., and the reel main body whose size is stabilized can be obtained.

Abstract: PURPOSE:To accurately secure a seam allowance and also to improve the handling facilitation of a model producing device by deciding the turning direction when a stitching line is supplied and calculating the data on a connected part concerning the shape of the connected part in accordance with the decided turning direction. CONSTITUTION:A deciding means automatically decides a right or left turning direction for input of a stitching line so that the input way of the finishing line can be detected. A computing means computes the data on a connected part concerning the shape of the connected part based on the deciding result of the deciding means and in accordance with the input way of the stitching line. Therefore a satisfactory connected part can be set even with either one of right and left turning direction set for input of the stitching line. Furthermore the stitching line can be freely supplied in either right or left turning direction. Thus it is possible to accurately secure a seam allowance and also to improve the handling facilitation of a pattern producing device.
