Title: Magnetic recording and reproducing device
Inventor: KOYAMA NORIYUKI
IPC: G11B15/02
Filed: 1992-05-27
Abstract: PURPOSE:To execute an REW mode so that the cut of the heading of reproduced information may be reduced in the case of loading a small-sized magnetic tape cassette in a magnetic recording and reproducing device which can perform recording/reproducing to a different type of magnetic tape cassette. CONSTITUTION:In the case of designating the REW mode from an operation part 34 in a state where the cassette is loaded in a VHS/VHS-C common VTR, a cassette kind discrimination part 36 discriminates the loading of the VHS-C standard cassette 1c. When leader tape detection parts 16 and 17 detect a leader tape, a microcomputer circuit 35 executes REW at low speed after REW operation is temporarily stopped, and the REW at low speed is stopped when output from the Hall element 37 of an FG generation part provided in a take-up reel 15c is stopped. Thus, the recording starting point 38 of a magnetic tape 8c is made close to a head cylinder 9 to reduce the cut of the heading.

IPC: B29C59/02
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To form a dent having desired shape by pressing an indenter on the mold matrix surface over several times on the same position during formation of the dent. SOLUTION: The surface of a mold matrix (cavity surface) comprising a martensitic stainless steel is subject to a metal polishing process so as to form the cavity surface of the mold matrix in the mirror surface. Firstly, an indenter 1 is pressed on the cavity surface at a pressing force F1. After the dent is formed on the full surface of the cavity surface at the pressing force F1, the indenter 1 is then pressed on the formed dent at the pressing force F2 larger than F1. Further, the indenter 1 is pressed on the formed dent at the force larger than the pressing force F2. The pressing force is gradually increased and pressed over several times, which controls the lateral shift of materials 2a which are the adjacent boundaries of the bent of the mold matrix 2 and forms the dent precisely, so as to obtain a mold with good transfer rate.

Title: Ink jet recorder
Inventor: TERASAWA HIROHARU
IPC: B41J2/185
Filed: 1985-07-19
Abstract: PURPOSE:To ensure that an ink can be stably ejected even after a long off-use period and is prevented from being wasted, by a system wherein when a power source is switched ON, the temperature in the vicinity of a recording head is detected, and an ink-restoring operation is automatically performed when the detected temperature is lower than a reference value. CONSTITUTION:When the power source is switched ON, the temperature in the vicinity of the recording head 5 is detected by a temperature sensor 9, and when the detected temperature is lower than a preset reference temperature (e.g., 37 deg.C), a pump 8 is automatically driven to perform the ink-restoring operation in which an ink is sucked and blindly ejected from the head 5. When the detected temperature is not lower than the reference temperature, the ink- restoring operation is not conducted. When performing the ink-restoring operation, a heater is automatically turned ON simultaneously with or after the ink-restoring operation, thereby heating the head 5 to the reference temperature.

Abstract: PURPOSE:To hold always a specified amt. of a lubricant on the front surface of the magnetic recording medium by adopting the structure in which the impregnation concn. of the lubricant in a part of the inside magnetic recording medium is higher than the impregnation concn. of the lubricant nearest the front surface of the magnetic recording medium. CONSTITUTION:The magnetic recording medium 1 is constituted by providing a magnetic film 3, a substrate 1, and a surface lubricant 4 on the film 3 or a lower layer film 2 between the film 3 and the substrate 1. The pores continuous from the front surface down to the deep part are formed in this medium. The density of the pores into which the lubricant can impregnate is so set that the the parts having the pore density higher than the pore density nearest the front surface of the magnetic recording medium exist in the deep part of the recording medium. The lubricant of the amt. sufficient to fill the pores is impregnated into the pores. The lubricant molecules impregnated into the pores of the film 3, the film 2, etc., are moved from the side of the higher concn. to the lower concn. by the concn. gradient of the lubricant molecules in the film according to the diffusion mechanism in proportion to this concn. gradient. Therefore, the parts having the higher lubricant impregnation concn. than the lubricant impregnation concn. nearest the front surface exist in the inside of the magnetic recording medium and the lubricant on the front surface is captured in the internal lubricant by this concn. gradient, by which the amt. is maintained always constant. The high mechanical reliability is obtd. in this way and the generation of head crash, etc., is prevented.
