Title: Search method for magnetic tape amd reproduced device used therefor
Inventor: YAMASHITA TATSUMARO
IPC: G11B27/28
Filed: 1991-11-15
Abstract: PURPOSE:To efficiently perform a search operation by simultaneously reading a preliminary recording zone in a forward recording area and a preliminary recording zone in a reverse recording area by magnetic heads and simultaneously searching the forward and reverse recording areas. CONSTITUTION:Program searching signals D1 in subcodes 8 and 9 for searching, recorded in the preliminary recording zones A1 and B1 are reproduced by high speed reading to be in an envelope waveform respectively. These envelope waveforms can simultaneously be obtained on both sides of A and B, and hence the head of a target data is searched only by one-way traveling of the tape. Since a buffer for the above is provided, even when the program search signals D1 are simultaneously read out of the preliminary recording zone A1 on the side of A and the preliminary recording zone B1 on the side of B, time lag can be effected between reproduced signals from two heads 17, and 18, and hence the envelope signals to be sent simultaneously from the individual preliminary recording zones A1 and B1 on the sides of A and B are separately recognized.

Title: Oil feeder for rotary compressor
Inventor: RI NARITADA
IPC: F04C29/02
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To supply lubricating oil to respective parts of a compressor and to prevent occurrence of abnormal abrasion and noises generated during operation by disposing a lubricating oil valve means in an oil chamber so as to be selectively close a cooling lubricating oil introducing pipe. SOLUTION: An elastic means 86 fixed to one end of a vane member 72 is contracted or expanded due to rotation of a roller member 54 in a cylinder member 70. Capacity in an oil chamber 60 is increased or decreased to vary pressure. When the vane member 72 is moved from a lower portion to an upper portion, the capacity of the oil chamber 60 is increased, while the pressure is decreased. The lubricating oil suctioned through a cooling lubricating oil introducing pipe 62 flows into the low pressure oil chamber 60 through the cooling lubricating oil introducing pipe 62 while pushing up a valve means for the lubricating oil. It is thus possible to prevent contraflow of the oil flowing into the oil chamber 60, and to sufficiently supply the oil to an outer peripheral surface of a crankshaft 52.

Title: Earth terminal receiving jig
Inventor: YONEKAWA TAKAHIRO
IPC: H01R4/64
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To easily attach/detach an earth terminal and ensure retention of the attached earth terminal. SOLUTION: A spherical body part 4 is provided on an upper end of a shaft body part 3 standingly installed on a receiving part 2. A diameter of the spherical body part 4 is larger than a diameter of the shaft body part 3 and smaller than a diameter of an attachment hole 91. An earth terminal 90 held by a hand is attached to the shaft body part 3 with the body part 4 passed therethrough. When the earth terminal 90 is removed, the earth terminal 90, being held substantially at a level by a hand, is lifted up with the attachment hole 91 aligned with the body part 4. The earth terminal 90 in an attached state, when lifting force from a wire 92 acts thereon, can not be removed.  The reasons are that there are many cases where the said lifting force tilts the earth terminal 90 and that the attachment hole 91 of the earth terminal 90 can not be aligned with the body part 4 by the said lifting force.

Title: Method for evaluating oriented film for liquid crystal display device
Inventor: AOYAMA RIYOUKO
IPC: G02F1/1337
Filed: 1988-12-27
Abstract: PURPOSE:To allow the normal/defective condition decision of orientability to be executed before a cell is assembled, i.e. in the stage when a oriented film is formed by cooling the oriented film on a substrate to cause frost setting on the surface thereof and deciding the normal/defective condition of the orientability thereof from the density and distribution of the water drops generated by the frost setting. CONSTITUTION:The glass plate 8 on which the oriented film 7 is formed is imposed on a cryogenic plate 3. The plate 3 is cooled by a cryogenic device 1 cooled by a cryogenic controller 2 to cool the oriented film 7 on the glass substrate 8. The moisture in the atm. air near the surface of the oriented film 7 condenses and the water drops by the frost setting are generated on the surface of the oriented film 7 at this time. This frost setting condition is taken by a camera 4 and the image thereof is displayed on a display 6 via an optical fiber 5 to make decision. The water drop distribution is nonuniform; for example, the density of the generated water drops is varied at a certain point, if the orientability of the oriented film is nonuniform; therefore, the normal/defective condition of the orientability of the oriented film 7 is decided by observing the density and distribution of the water drops generated by the frost setting.
