Title: Equipment for heating hollow steel tube
Inventor: NAKAJIMA NORIO
IPC: C21D9/08
Filed: 1995-06-16
Abstract: PURPOSE: To provide heating equipment for a hollow steel tube, which prevents a roller and a roller bearing device, etc., from being damaged owing to high heat even without adopting a cooling system. CONSTITUTION: Since the roller 41 is not cooled, the thermal efficiency is very high and a cooling system is unnecessitated. Since the roller shaft part 42 is not cooled and is a cylindrical type, the hollow steel tube supporting part 43, the roller shaft part 42 and the inner part of the roller shaft part 42 can be made to be the same temp. as a furnace temp. In the latter half part, the hollow steel tube 1, the recessed supporting surface 46 and the furnace can be made to be the same temp. and the inner part and the outer part thereof can be made to be the same temp. and the temp. difference is not developed. It can be prevented with a heat shielding device 50 to conduct the heat at the roller shaft part 42 side to the roller bearing part 44 side.  The contacting part of the hollow steel tube supporting part 43 with the hollow steel tube 1 is formed of high quality heat resistant and wear resistant material to reduce the damage caused by the heat.

Title: Copying machine
Inventor: KUSUMOTO KEIJI
IPC: G03G21/14
Filed: 1990-06-07
Abstract: PURPOSE:To prevent toner from being consumed unnecessarily when recording forms run short by holding a toner image on an intermediate transfer medium and interrupting an image forming process if the shortage of the recording forms is detected during the image formation, and carrying on the image forming process when recording forms are supplied. CONSTITUTION:When forms P in form cassettes 43 and 44 run short, a CPU sets an image formation interruption flag, turns off a main motor 42 to stop the conveyance of forms, and resets a paper feed permit flag and sets the image formation interruption flag. Then paper emptiness sensors 83 and 84 check whether or not there are forms P in the form cassettes 42 and 43 and when forms P are supplied, the image formation interruption flag is reset and an image formation state is put back to an image formation state following the image formation state at the time of the interruption of the image formation. Consequently, the unnecessary consumption of toner at the time of the shortage of recording paper in copying operation is prevented.

Title: Acceleration/deceleration method for locus direction of moving member
Inventor: SHIRAE TAKASHI
IPC: G05B19/416
Filed: 1989-06-14
Abstract: PURPOSE:To attain a smooth movement without stopping a locus when a moving member changes in an orthogonal movement and a joint movement by independently accelerating and decelerating the orthogonal movement and the joint movement and respectively adding them. CONSTITUTION:An instruction is read from RAM. When it is a moving instruction, a moving quantity at that time is calculated and the data is transferred to an interpola tion processing. The moving quantity in unit time is obtained in the interpolation processing, and it is recognized whether a moving instruction is the orthogonal move ment or the joint movement. Then, orthogonal components and joint components are processed by different algorithms. When a new movement is the orthogonal move ment in the movement different from the present movement, namely, the present joint movement, the processing of a deceleration quantity is executed. When it is the orthogonal components, a system changes to the joint movement after the accelera tion processing. Next, both results are added and the result is outputted to the driving part of a joint axis as a servo command. Thus, smooth movement can continuously be executed without permitting the moving member to stop between two kinds of operations of the orthogonal movement and the joint movement.

Title: Manufacture of micromachine
Inventor: UEDA MINORU
IPC: B23P15/00
Filed: 1991-05-24
Abstract: PURPOSE:To form parts for a micromachine with high precision by using ceramics, containing a specified element, for a sacrifice layer finally removed when a mircomachine is manufactured on a base sheet, such as Si. CONSTITUTION:Ceramics containing are rare earth elements Ba, Cu, and 0 used as a sacrifice layer selectively removed. Concretely, Re-Ba-Cu-O ceramics material, wherein Re is a rare earth element, that is, Y, Dy, and Ho, is preferable, and, for example, Y1Ba2Cu3O7-x is used. Since the ceramics material is dissolved in acid of low density, only the sacrifice layer can be removed without lowering precision of a formed machine element. Further, the ceramics material can be used to form a film through spray, step coverage is excellent, and hole-filling is also practicable. Moreover, since the ceramic material often has a two-dimensional crystal structure, a flat and smooth layer can be formed on the surface of the sacrifice layer.

Title: Large-sized injection molding machine
Inventor: YASUIKE AKIO
IPC: B29C37/00
Filed: 1978-12-05
Abstract: PURPOSE: To provide an injection molding machine with a preplasticizing means which is low in energy consumption and easy to operate and which rarely gets troubles, the molding machine being operated by using a hydraulic pressure which is increased by applying an air pressure to the oil, whereby a hydraulic pump can substantially be omitted.  
     CONSTITUTION: A resin is plasticized in a pre-plasticizing means 2, which is operated by an electric motor 1, and transferred under pressure into a resin accumulator 5. As a result, an operation oil in that portion of the interior of a hydraulic cylinder 7 which is opposite to a piston rod with respect to the piston therein is compressed into a hydraulic pressure accumulator 8. A hydraulic pressure is thus stored in the accumulator 8. The resin in the accumulator 5 is automatically injected into a mold 17 when a nozzle valve 9 is opened. Namely, the injection of resin is effected by a pressure generated by the pre-plasticizing means 2 without using a hydraulic pump. All of hydraulic pressure change-over valves used for clamping, opening and closing the mold consist of check valves 27, 28, 30. The mold is opened and closed by a hydraulic pressure increased to a low level by a large-diameter air cylinder 25. The mold is clamped by a small amount of an operation oil the pressure of which is increased to a high level.
