Title: Heat resistant cast steel
Inventor: SUGITANI JIYUNICHI
IPC: C22C38/54
Filed: 1981-06-13
Abstract: PURPOSE: To obtain a heat resistant cast steel with excellent creep rupture strength at ≥ about 1,000°C high temp., excellent thermal impact resistance, etc. by adding N, Ti and Al or B to a heat resistant cast steel contg. Cr, Ni and Nb.  
     CONSTITUTION: This heat resistant cast steel consists of, by wt., 0.3W0.6% C, ≤2.0% Si, ≤2.0% Mn, 20W30% Cr, 30W40% Ni, 0.3W1.5% Nb, 0.04W0.15% N, 0.04W0.15% Ti, 0.02W0.07% Al or 0.0002W0.004% B and the balance essentially Fe. N stabilizes and strengthens the austenite phase in the form of solubilized nitrogen, and it forms nitride together with Ti, etc., makes the grains fine, and inhibits the growth in the presence of Al or B, thereby contributing to improvements in the strength at high temp. and the thermal impact characteristics. Ti and Al show said effects. B strengthens the grain boundaries of the steel matrix, and it prevents a Ti-base precipitate from coarsening, contributes to the formation of such a fine precipitate, and retards the cohesion and coarsening after the precipitation, thereby enhancing the creep rupture strength.

IPC: B65D65/40
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To improve barrier properties to an oxygen, a steam and to obtain transparency by forming a barrier layer of a thin film having a specific internal compression stress. SOLUTION: The gas barrier film 1 comprises a base material film 2, and a barrier layer 3 formed on one surface of the film 2.

Title: Garbage disposer
Inventor: ISHIBASHI TAKAFUMI
IPC: F26B9/06
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a garbage disposer in which heating treatment is appropriately performed at the shortest necessary time without receiving effect by ambient temperature in the automatically finishing garbage disposer. SOLUTION: A controlling means 35 starts a time check of set time T from a point of time when only a first set temperature Δt1 is lowered for the highest value of temperature inputted from a second temperature sensor 34 during generation of steam. A drying heater 23 is continuously heated and operated. It is judged at any time whether a fall of at least a second set temperature Δ2 is not caused for the temperature inputted from the second temperature sensor 34 at this time.

Title: Size measuring instrument
Inventor: MUNAKATA HIROAKI
IPC: G01B21/00
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To realize a high-precision measurement with a small-sized, lightweight device by detecting magnetic poles of a linear scale which has N poles and S poles alternately along the moving direction of a needle. SOLUTION: A linear motor unit 2 constituted by putting a linear motor 4 and a displacement detecting member 5 in a case 3 is set right above a body to be measured which is held on a substrate and after a spherical measuring element 1 mounted on top of a shaft 20 is set opposite the body to be measured, a sine wave driving current is selectively supplied to flat coils 72 and switched in direction to move the needle 7 linearly. The winding directions of the coils 72 cross the magnetic flux of a permanent magnet at right angles, so the needle 7 is given an X-directional or Y-directional thrust and the needle 1 moves linearly.  For example, when the height or step of the body to be measured is measured, the linear scale 52 cooperates with a magnetic sensor 53 and the movement quantity of the measuring element 1 can be detected from their relative movement, so the size can be measured by subtracting the movement quantity from the distance between the measuring element 1 and substrate.

Abstract: PURPOSE:To lower an air blowing noise by providing an extendedly provided part, which extends from a side plate side to a main plate side, neighboring the inner periphery of an impeller, in a prescribed range directing from the vicinity of a reed part of a housing toward the volute expanding direction. CONSTITUTION:A first extendedly provided part 11 is extended/formed in a region corresponding to a prescribed range, being directed from the vicinity of a reed part 21 of a housing 1 toward the volute expanding direction. This first extendedly provided part 11 is extended/provided from a side part (5) side toward a main plate (4) side, neighboring the inner periphery of an impeller 2. With this, in the reed part 21, the vicinity of a leading edge inclining to the side plate 5 of a blade 3 turns to a dead water region, because of the extendedly provided part 11. Accordingly, an occurrence of a circulation flow in the vicinity of a leading edge 1a can be restricted. In addition, an air blowing noise caused by both the turbulence accompanying the occurrence of the circulation flow and entrained air can be reduced, thereby realizing calm operation.

Title: Surface acoustic wave device, its manufacture and communication equipment using the device
Inventor: SHIBA TAKASHI
IPC: H03H9/145
Filed: 1989-04-14
Abstract: PURPOSE:To improve the deterioration of a characteristic beyond a band owing to a diffraction effect by installing a waveguide which feeds disturbance to the propagation direction of a wave propagated in a direction which is obliquely inclined with respect to the propagation direction of a surface acoustic wave. CONSTITUTION:Acoustic materials 4 are applied on both sides of input output interdigital electrodes 2 and 3 for suppressing a reflected wave from an end surface. A metallic film 5 is formed between the input output interdigital electrodes 2 and 3 and a part 6 where the metallic film does not exist is formed in the metallic film 5 in a V-shaped. Then, a diffraction wave is totally reflected by an interface 7 between a part where the metallic film exists and the part where the metallic film does not exist 6, and disturbance is given to the propagation direction of the wave propagated to the obliquely inclined direction with respect to the propagation direction of the surface acoustic wave propagated to a vertical direction with respect to the digits of the interdigital electrodes 2 and 3, whereby an output-side is prevented from receiving disturbance. Thus, the correlation characteristic of an input/output is deteriorated, and the diffraction wave can effectively be suppressed. Consequently, a suppression degree beyond the filter band improves, and the interference removing performance of the filter improves.
