Title: Inspection of crack in tile
Inventor: NAWA KUNIHIRO
IPC: C04B41/85
Filed: 1993-02-06
Abstract: PURPOSE:To make it possible to discover a crack without fail by a method wherein an inspecting solution prepared by making a solvent contain a coloring pigment is applied to the surface of a tile. CONSTITUTION:When an inspection solution 10 is applied on the surface of a tile 12, the solution 10 permeates into a crack 14, if it exists in the surface, due to the permeability of thinner. Air inside the crack is expelled by the solution 10 and foam 16 is produced. When the liquid 10 gets into the crack 14, besides, the deepness of a color of the part of the crack 14 becomes larger than that of the other part and a line of deeper yellow than in the other part appears along the crack 14. From these phenomena, accordingly, the existence of the crack 14 is perceived easily even by the naked eye and thus it can be confirmed simply.

Filed: 1985-03-07
Abstract: PURPOSE:To obtain a Schottky diode with favorable reproductivity and thermally stable by a method wherein the temperature of a substrate in sputter is changed in two stages so as to form a metal nitride film with high-melting point and less reactive with a semiconductor on such III-V group compound semiconductor. CONSTITUTION:After a Si-doped gallium arsenide substrate 1 is etched, the substrate is nitrogen-blown, and sputtered tungsten targets to form a tungsten nitride thin film 2 with W2 N phase. Then, the substrate 1 is again sputtered to form a tungsten nitride film 3. The substrate undergoes reactive ion etching with the mask of a resist 4 so that the tungsten nitride thin film 2 and the tungsten nitride film 3 are left with a circular pattern. A silicon nitride film 5 is laminated, and then gold, germanium and nickel are evaporated on the back side of the substrate and alloy-processed to produce a diode with Schottky electrodes of a tungsten nitride thin film 2 and a tungsten nitride thin film 3. The said method in which the temperature of the substrate is changed to produce a diode makes it possible to stably form the tungsten nitride film 2 on the gallium arsenide substrate 1.

Title: Silencer for refrigerant compressor
Inventor: KAWAI HIDEKI
IPC: F04B39/00
Filed: 1982-03-18
Abstract: PURPOSE:To prevent a muffler from play due to a gap between the muffler and a cylinder head by forcing a communicating pipe through a hole in the muffler into an intake port of the cylinder head to attach an elastic body to the outer periphery of the communicating pipe between said pipe and the cylinder head. CONSTITUTION:In the beginning of running a compression element 3, a cylinder head 7 is given high temperature by discharge gas to expand a communicating pipe 16 together with a main body 14. A force, however, is produced in the direction of pulling out the communicating pipe 16 by the expansion of the main body 14 due to the difference of coefficient of linear expansion. When said pipe 16 is forced into the main body to minimize an elastic body 19, it is pulled out against the press-in force by an amount corresponding to the expansion of said body 19. Also, when the communicating pipe 16 is pressed in so as to leave slight elasticity of said body 19, the expansion of said body 14 contracts the elastic body 19 so that the communicating pipe 16 is not pulled out. The temperature of the head 7 is varied with the intermittent running while the expansion of the main body 14 is absorbed by the elastic body 19 without producing any play of the main body 14.

Title: Moving picture block decision circuit
Inventor: YAMORI AKIHIRO
IPC: H04N19/423
Filed: 1994-03-15
Abstract: PURPOSE:To prevent errors from being accumulated between plural successive frames by deciding a current block as an effective block even if ineffectiveness is decided when the block difference between the decoded signal of a frame of last encoding in the frame memory of an inter-frame encoding circuit and the input signal of a current frame is larger than a threshold value. CONSTITUTION:A moving picture block decision circuit 1 is used in front of the low-bit-rate inter-frame encoding circuit 30 for a moving picture of video conference, video telephone, etc., and decides whether or not encoding is performed by deciding whether a moving picture block is effective or ineffective. Then when the block difference between the encoded signal of the frame of last encoding and the input signal of the current frame is larger than the threshold value, the block is decided as the effective block even if it is decided that the block is ineffective from the difference between the input signal of the frame of the last encoding and the input signal of the current frame. Consequently, the circuit is adaptive to slight motion of an image while the generation of an encoded information amount of a background image is suppressed, and errors of motion are not accumulated.
