Title: Heat resistant chromium steel
Inventor: KURIYAMA MITSUO
IPC: C22C38/00
Filed: 1980-05-09
Abstract: PURPOSE: To obtain a heat resistant chromium steel having a totally tempered martensite structure with high strength at high temp. and high toughness at room temp. by further adding N to 11Cr1MoCuWNiVNb steel obtd. by adding Cu, W and Ni to 11Cr1MoVNb steel.  
     CONSTITUTION: This heat resistant steel for the shaft of a large-sized steam turbine rotor consists of, by wt., 0.1W2.5% C, 9.5W12.5% Cr, 0.5W2% Mo, 0.3W1.5% Ni, 0.4W1.5% Cu, 0.1W0.3% V, 0.05W0.5% W, 0.03W0.2% Nb, ≤0.7% Si, ≤1.5% Mn, 0.03W0.1% N and the balance Fe, and it is heat-treated without forming δ-ferrite. Even if one of Cu, W, Ni and N is removed, they can not produce a sufficient effect, and by the action of Cu, a toughness reduction due to N is prevented. W, Cu and N increase the toughness, yet above the upper limit of Ni lowers the strength at high temp. N is required to increase the strength at high temp., yet above the upper limit of N deteriorates the quality of the ingot.

IPC: A23G9/28
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To simply carry out tilting operations of a dispensing cylinder of an apparatus for dispensing ices such as ice cream or yogurt. SOLUTION: This apparatus comprises a dispensing cylinder 12 placed on a carrier plate 41 and tiltably supported by the back surface of a heat insulating door 3 with a hinge 48.

Title: Graphic accelerator
Inventor: ICHIMURA SATOKICHI
IPC: G09G5/36
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To avoid imposing on development due to high extendability and to improve a performance by providing a display switching part provided with a timer to avoid switching to a picture prepared by another graphic accelerator in a prescribed time. SOLUTION: The graphic accelerator 20a prepares a two-dimensional picture and displays it on a display 30 via the display switching part 25. The part 25 provided in the accelerator 20a measures a time for preparing a two-dimensional picture for one screen since a geometry arithmetic part 21 receives an instruction by means of a timer and keeps displaying this picture during 1/2 of this time. When a three-dimensional picture displaying instruction to a next display list is issued from an application 12, a driver 14 issues a group of instructions for one screen only to a graphic accelerator 20b. Thus, double plotting performance is obtained and a three-dimensional picture can smoothly be displayed.

IPC: H01S5/10
Filed: 1994-03-30
Abstract: PURPOSE:To emit the whole of light within a resonator part and to efficiently infect carriers into an active layer by forming a pn junction in the lateral direction within a quantum well active layer and using a facet part produced when laminated as a resonator. CONSTITUTION:The layer on a quantum well active layer 15 represented by oblique lines on the (111) plane in which Si is doped is made into a p-type region 18 and the other part is made into an n-type region. A pn junction is formed of the boundary between a (111) A plane and a (114) A facet part, and light is emitted by the quantum well active layer 15. The light emission is resonant with a microresonator formed in the (114) A facet part to form a standing wave. At that time, the quantum well active layer 15 is located in the position of the antinode of the standing wave to resonate and to amplify natural emission light. Therefore, finally an n electrode 20 is formed on a (001) plane of a difference-in-level plane and an electrode 21 is formed on the other plane than the (114) A facet part, thereby being able to increase light emission efficiency.

Abstract: PURPOSE: To provide a safe weight balancer without heavy goods falling in the weight direction even if a spring breaks, by providing a compressive spring between a first spring seat and a second spring seat. CONSTITUTION: A rod 35, whose tip is coupled with the coupling part PX of a movable member 2, pulls the movable member 2 down half right by a compressive spring 31 provided between first and second spring seats 33 and 34 exerting force in the direction of separating the second spring seat 34 from the first spring seat 33, whereby the force equivalent to a weight W2 into vertical direction works. This way, the heavy goods WP can be changed in horizontal and vertical direction, and to this change, the balance of heavy goods WP can be always kept with one piece of compressive spring 31. Moreover, even if the compressive spring 31 breaks, the compressive spring 31 draws the movable member 2 in the vertical direction, so the heavy goods WP never falls.

Title: Quality deciding device
Inventor: NAKAZAWA KOUJI
IPC: G11B3/44
Filed: 1982-04-16
Abstract: PURPOSE:To decide the quality for the notched shape of a work when a VDP diamond stylus, etc. is decided, by providing a slanting surface having an adjustable angle of inclination and a feeder which feeds a work onto the slanting surface. CONSTITUTION:A jewel 2 like diamond, etc. is fixed at the tip of a round rod work 1. A cover 4 is provided to the tip of a feeder 3 which feeds the work 1. Then the work 1 is successively fed onto a slanting surface 10 of a slanting stage 5 by means of a vibrator 7. In the case of a nondefective work 1 having a sufficiently large width of a notched surface A, the rolling of the work 1 stops on the surface 10 when the surface A is brought into contact with the surface 10. Thus the work 1 is held on the surface 10. While in the case of a defective work 1 having a small width of the surface A, the rolling of the work does not stop although the surface A is brought into contact with the surfacd 10. Thus the work 1 rolls down to a conveyor belt 6. In such a way, the angle of the surface 10 can be controlled properly to decide the quality of the surface A of a work 1. It is also possible to set the vibrator 7 to the stage 5.
