IPC: B30B15/26
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To improve working performance by easily solving the conventional problem in which the press was unfit for precision forming because viscosity changes by oil temperature, changing the position of a ram and giving rise to variance in the forming. SOLUTION: This method is such that a punch command b1 is given at the upper end (a) of the piston 3 stroke, that a temperature drift Δε of the piston 3 is measured after the elapse of a prescribed time with the dispensing completed c1 and that, with the upper end (a) of the piston 3 stroke corrected by feeding back from the temperature drift Δε each time, the next punch command is given.

Title: Disk transferrer
Inventor: YAMABE SHINICHI
IPC: B25J15/08
Filed: 1990-08-23
Abstract: PURPOSE:To shorten the time required for disk transference and thereby perform a job for transfer operation so efficiently by installing a dislocation compensating mechanism, absorbing both longitudinal and tilting dislocation, in space between a grip claw and a hand. CONSTITUTION:Supposing that all receiving members 7 cause dislocation to the side going away from an industrial robot, displacement compensation takes place, and a difference between this virture dislocation and the actual dislocation is absorbed by longitudinal slide motion of a slide mechanism 13 and horizontal rocking motion of a rocking mechanism 20. At this time, a contact piece 26 comes into contact with an outer end face of the receiving member 7 precedent to other members, having its absorbing action produced in the slide mechanism 13 and the rocking mechanism 20.

Title: Manufacture of semiconductor thin film
Inventor: TAMURA MASAO
IPC: H01L21/203
Filed: 1992-08-24
Abstract: PURPOSE:To uniformly reduce the density of threading dislocations by inserting, into a semiconductor heteroepitaxially grown film, a single crystal thin-film whose lattice constants are largely different from those of the grown film and whose modulus of rigidity is larger than that of the grown film, dividing those films, and subjecting those films to a heat treatment. CONSTITUTION:After a silicon substrate 5 is subjected to proper chemical cleaning and then placed in a molecular beam epitaxy(MBE) device, it is heated at about 900 deg.C for 15 minutes and an oxide film on the substrate surface is removed. Then, an AlAs buffer film 8 of a 10-atom thickness is grown at 400 deg.C. Then, a GaAs film 6 of a l-mum thickness is grown at 600 deg.C at a growth rate of about 1mum/hour. Next, a Ge thin-film 7 of a 200-nm thickness is grown at 400 deg.C, and a GaAs film 6 of a 1-mum thickness is grown again. Then, cutting and a heat treatment are performed. As a result, it is confirmed that the density of dislocations is less than 10<4>/cm<2> in any divided region.

Title: Gas storing method
Inventor: INOMATA KIYOTO
IPC: F17C11/00
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To obtain a gas storing method that enables to store a large amount of gas in a container. SOLUTION: In this gas storing method, gas is introduced into a container filled with fine-hole materials at high pressure higher than 20 barometric pressure. And then the fine-hole materials of which diameter is 0.9 nm or below occupy at least 5% or more of whole capacity in the container when it is filled. Hence, larger amounts of gas than the mere gas filling amounts equivalent to the extrapolation value to high pressure with adsorptive feature at the measurement of gas less than 20 barometric pressure to the fine material can be filled in the container. Also, larger amounts of gas than the gas filling amounts by mere pressure filling to the container to which fine-hole material is not filled can be filled in the container.

Title: Optical part supporting device
Inventor: MATSUSHITA TETSUYA
IPC: G03B27/54
Filed: 1987-09-08
Abstract: PURPOSE:To simply adjust levelness and to improve workability by supporting one of sliding members fitted to both the end parts of a supporting frame on which an optical part is fixed so as to adjust the vertical position of the member through an eccentric cam mechanism. CONSTITUTION:The levelness of a 1st supporting frame body part 51 is controlled by rotating a control member 56 while holding a control 56d under the loosened state of an undrawing member 51d. After completing the control of the levelness, the control member 56 is fixed by screwing the undrawing member 51d into the hole.

Title: Armature for motor
Inventor: MORITA KAZUHIKO
IPC: H02K13/04
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To obtain an armature which prevents the disconnection of the terminal of an armature coil, by a method wherein the maximum value of a bending stress acting on the terminal of the armature coil is situated in a position in which the armature coil is loosened. SOLUTION: When an armature is turned, a tool which is attached to its tip is driven, and it is unavoidable that a vibration is generated. Due to the vibration, a bending stress acts repeatedly on the terminal of an armature coil 2, and the bending stress becomes maximum in the terminal. Then, the terminal is fixed to a resin part 1b via a varnish. However, since also tension is applied to the part, there is a fear that the part is disconnected due to the bending stress which acts repeatedly. Then, when the protruding length of the resin part 1b is made long, a position in which the repeatedly acting bending stress becomes maximum is situated in a part in which the terminal of the armature coil 2 is loosened.  In this manner, since the maximum position of the repeatedly acting bending stress is situated in the part in which the terminal of the armature coil 2 is loosened, possibility that the terminal of the coil 2 is disconnected is reduced.
