Title: Liquid jet recording head
Inventor: MASUDA KAZUAKI
IPC: B41J2/055
Filed: 1986-12-19
Abstract: PURPOSE:To make nozzles to be enhanced in density and to eliminate the problems of the short life and higher cost of a heating element to obtain a long life, by a method wherein an elastic film body having magnetism and capable of being deformed and restored by magnetizing and demagnetizing a magnetic force generation means is provided on the wall surface of a liquid path within a magnetic field of the magnetic force generation means disposed along the liquid path. CONSTITUTION:When a pulse electric signal is applied to a film coil 2 to generate a magnetic field, an iron piece disposed above of the film coil 2 is applied with an attraction force due to lines of magnetic force and thereby a resin film 11 is deflected toward the coil 2 and the capacity of a flow path 6 is rapidly reduced and then a recording liquid is discharged out of an orifice 5. When the applied pulse is cut off, the resin film 11 is restored to the former position due to the elasticity of its own. The space surrounded by a support board 8, a top board 9, and the resin film 11 is made to be completely sealed. Therefore, the space is in a negative-pressure state when the resin film 11 is deformed toward the coil 2. This state aids the restoring force of the resin film 11 due to the elasticity of its own when the signal is cut off.

Title: Packet exchange type lan
Inventor: SHIBATA TETSUYA
IPC: H04L12/40
Filed: 1987-11-30
Abstract: PURPOSE:To simplify the control for a newly participated station by adding a packet after final station packet of a transmitted packet group regardless of the absolute number of the newly participated station to participate the newly participated station. CONSTITUTION:When a station is participated newly, a station N sending a packet before a station whose logic number is 0 is retrieved, and after the station sends a packet next, a packet having a logic number (N+1) being the logic number of said station added by 1 and informing the increase in the station number is sent. In this case, the station whose logic number is 0 increases the packet transmission monitor logic number by one as (N+1). The other station revises the packet transmission timing of its own station. The station whose logic number is 0 awaits the preceding station (N+1) completing the packet to check if a new station is to be participated and after awaiting by a time T, then awaits by a minimum time Tp in which a station participated newly can sends a packet, and then sends the packet.

Title: Crawler support mechanism of crawler type vehicle
Inventor: HIRANO HIROSHI
IPC: B62D55/108
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To employ an independently suspending type suspension. SOLUTION: A double wishbone type suspension 11 is placed between the body 2 and the crawler 3 of a crawler type vehicle. The oscillating end 13a of the suspension 11 is connected to the truck frame 31 of the crawler 3 via elastic members 23, 24.

Title: Production of high-purity isophthalic acid
Inventor: OGOSHI FUMIO
IPC: C07C51/29
Filed: 1992-11-12
Abstract: PURPOSE:To produce high-purity isophthalic acid by a simplified process in high yield by oxidizing a m-dialkylbenzene in a liquid phase to give a reaction run-off material, removing dissolved oxygen in the reaction run-off material, hydrogenating and purifying. CONSTITUTION:A m-dialkylbenzene, preferably m-xylene, is oxidized with molecular oxygen in a solvent of acetic acid in the presence of a heavy metal such as cobalt and manganese or the heavy metal and a bromine compound. The prepared liquid-phase oxidation reaction run-off material is directly subjected to a deoxidizing process (e.g. introduction of inert gas) to remove dissolved oxygen or diluted with acetic acid or water newly and dissolved oxygen is removed by the deoxidizing process. The resulting substance is brought into contact with a noble metal catalyst of group VIII supported on active carbon in the presence of hydrogen at 170-300 deg.C and then isophthalic acid is precipitated and separated. The separated filtrate is filtered, recycled and used as a solvent for liquid-phase oxidation reaction. Consequently yield of isophthalic acid is improved and further the catalytic component can be reused. Therefore yield of isophthalic acid is improved, the catalytic component can be reused and facilities for waste water treatment can simplified.

Title: Conveyor device
Inventor: IIZUKA YUKIO
IPC: B65G1/00
Filed: 1989-11-21
Abstract: PURPOSE:To make the direction of a load on the end part variable in a conveyor device in a clean room by providing a movable table having a load receiving table capable of being freely raised and lowered in a frame so that it can freely travel, and arranging a load receiving body on the end part of the travelling path of the movable table so that it can freely turn. CONSTITUTION:When a load is placed on a load receiving part 19, a load receiving table 64 is lowered to move a movable table 50 positioned in a slit 27 for lifting/lowering the load receiving table below the load 3. The load receiving table 64 is then raised to lift the load 3 to move the movable table along a travelling path. Then, a lift device 65 is lowered in opposition to an other load receiving part 19 to deliver the load to the load receiving part 19. A cutaway part in the turning part on the end part is connected to the slit 27 for lifting/ lowering the load receiving table to move the movable table 50 to load it on a load receiving body. Then, after the movable table 50 is retracted, the load receiving body is turned by a rotation driving device to change the direction of the load 3 to a load delivering position. The direction of the load can thus be changed.

Title: Tape cassette
Inventor: KONISHI AKIO
IPC: G11B23/087
Filed: 1993-12-02
Abstract: PURPOSE:To prevent a sliding member from easily moving rearward of a cassette and prevent a tape from being slack and improve a reliability by providing a pair of hook members at both ends of the inverse T-shaped sliding member. CONSTITUTION:Even when one tape reel 22 moves, a reel brake 32 is inclined within an area of d slide gap to a guide part 33 owing to an urging force of a coil spring 41 at the opposite side and therefore, the brake 32 is prevented from easily moving rearward of a cassette. A projecting/recessed part 29 in the outer periphery of the other tape reel 23 is consequently always meshed with a front end of a hook member 38, prohibiting the rotation of the reels 22, 23. In this manner, even if a tape cassette is dropped or vibrated to cause only one reel to move, the brake is difficult to follow the movement and the reel is always locked not to rotate, thereby to eliminate the slack and damage to a tape.

Title: Magneto-optical disk recording and reproducing device
Inventor: KAWAMOTO YASUKI
IPC: G11B11/105
Filed: 1988-11-29
Abstract: PURPOSE:To obtain the excellent quality of a reproducing signal by additionally providing a low pass filter, a differential amplifier and an amplifier. CONSTITUTION:A laser light beam reflected by a recording film 7 is separated by a polarized light beam splitter 10. The respective light quantities thereof are detected by photodetectors 11 and 12 and the difference between the light quantities is converted into an electrical signal by the differential amplifier 13. The variable frequency of the electrical signal by the rotational angle of the plane of polarization caused by the double refractivity is much lower than a recording frequency, so that the variation of the signal only caused by the double refractivity is obtained by removing high frequency component by the low pass filters 15 and 16 and a signal corresponding to the rotational angle of the plane of polarization caused by the double refractivity is obtained by getting a difference signal by the differential amplifier 17. Thus, the excellent reproducing signal is obtained in an output terminal 14 by driving the amplifier 18 with a feedback signal and removing the variation of the reproducing signal caused by the double refractivity so that the difference signal becomes zero.
