Title: Manufacture of offset deformed shaft member
Inventor: MIWA ETSUJIRO
IPC: B21K1/12
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To manufacture by cold forging an offset deformed shaft member having a notch part which is obtained by notching one side of the central line of a shaft at a shaft end part. SOLUTION: A part becoming an offset deformed part is constituted into a pre-process shaft product 11 which is formed into a tapered shape such as a conical shaft 14 or concave curved surface body 14' or convex curved surface body 14'' wherein a diameter D2 in the maximum diameter part is smaller than the diameter in the offset deformed part, the deformed part is gradually tapered from the maximum diameter part toward the tip end and the tip end part becomes the minimum diameter part or a shape wherein a columnar part 15 is further extensionally formed in the tip end of the tapered part.  In such a manner, since a load or a bias of the load which exerts on a cold forging die is largely reduced by tapering the tip end part of the pre-process shaft product 11 and making the tip end diameter small satisfactorily, the offset deformed shaft member is manufactured by cold forging from the pre-process shaft product 11, and whereby the working cost and equipment cost are reduced.

Filed: 1987-10-22
Abstract: PURPOSE:To facilitate evaluation by composing the circuit of >=2 arrays of shift registers in an optional number of stages whose inputs are connected to input terminals and exclusive OR or exclusive NOT whose inputs are connected to the outputs of the shift registers. CONSTITUTION:All D-FFs 11 with a resetting function which constitute shift registers 13 and 14 are reset through a reset terminal R and then optional data set for a clock terminal C is transferred to the FFs 11 in order. Here, if the inversion of the data as a single even is not caused at an optional FF 11, the outputs of the registers 13 and 14 are equal, so 'L' appears at the output of EX-OR (exclusive OR) 12 and an output terminal O. Further, when the inversion of the data is caused at the optional FF 11, on the other hand, data of the other FF 11 in the same stage with the optional FF 11 where the data is inverted and the data of said optional FF 11 are different and outputted from the registers 13 and 14 and 'H' appear at the output of OR 12 and the terminal O, so that the single event is easily evaluated.

Title: Production of fiber reinforced calcium phosphate compound ceramics
Inventor: ENOMOTO AKIRA
IPC: C04B35/80
Filed: 1988-10-26
Abstract: PURPOSE:To improve the strength and toughness of the manufactures of the title ceramics by successively preparing a product molded body and a pre-molded body from calcium phosphate compound powder and heat-resistant inorganic short fibers and calcining the pre-molded body at specific temp. CONSTITUTION:Calcium phosphate compound powder and heat-resistant inorganic short fibers are uniformly subjected to wet blending via a solvent; the mixture is then molded to obtain a product molded body. A calcium phosphate precursory soln. is impregnated into the product molded body, which is thereafter drited to form a pre-molded body at prescribed porous rate. As the third stage, the pre-molded body is calcined at >=600 deg.C to form fiber reinforced ceramics. By this method, the deformation and cutting loss of the heat- resistant short fibers are prevented to generate the condition where the short fibers are three-dimentionally and uniformly dispersed and tangled in the matrix. In this way, the strength and toughness of the ceramic manufactures are improved.

Title: Dynamic vibration-absorbing device
Inventor: FUJII SHIGEHARU
IPC: B23Q11/00
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To require no maintenance and provide a simple structure, an easy mounting property to a vibration object and excellent damping performance by repeatedly colliding a load mass body linked and fixed to a vibration body and a movable mass body movably retained to the load mass body by a vibration of the vibration body. SOLUTION: A movable mass body 6 is retained to a load mass body linked and fixed to a vibration body O. The movable mass body 6 is relatively moved to the load mass body by a vibration of the vibration body O and is repeatedly collided to the load mass body. A vibration energy of the vibration body O is used up by the collision between the load mass body and the movable mass body 6 and thereby, a vibration amplitude of the vibration body O is damped. If the load mass body and the movable mass body 6 are collided not depending on a vibration frequency of the vibration body O, since the vibration energy of the vibration body O is absorbed, the device can correspond to a vibration of a wide band area of the vibration body O.

Filed: 1987-10-23
Abstract: PURPOSE:To lessen the amount of a chemical liquid unused and remained in a case of a sprayer and to efficiently utilize the liquid, by providing a blast passage on the lower part of the case and a blast hole above the blast passage, opening inside the case. CONSTITUTION:When compressed air is sent through a compressed air pipe 5, a jet stream is gushed from a nozzle 4 and a negative pressure occurs in the clearance between the compressed air pipe 5 and a water inlet pipe 6. The level of liquid kept in a water passage 6a rises by ejection and the liquid is mixed with the jet stream. The gas mixed with the liquid is sent through an air outlet 8, collides with a baffle ball 9 to be radiately dispersed and is ejected from a spray nozzle 2. A sprayer constructed as above further includes a blast passage 11 and a blast hole 12. A blow is sent to the inside of a case 3 through a blast pipe 13, the blast passage 11 and the blast hole 12. The inner surface of the case 3 is surrounded with a weak stream and the liquid dispersed is thereby repelled and not adhered to the inner surface of the case 3. The liquid in the sprayer is thus substantially all atomized and ejected from the spray nozzle 2.

Title: Thermal recording medium
Inventor: NAGAHAMAYA YUUJI
IPC: B41M5/382
Filed: 1985-12-02
Abstract: PURPOSE:To provide a thermal recording medium capable of being used for printing and correcting, by a construction wherein the affinity of an ink layer for a recording paper is set to be stronger than the cohesive force of a releasable layer in a melted condition and to be weaker than the affinity of the releasable layer for the ink layer and the base layer in a solidified condition. CONSTITUTION:In a printing operation, when a thermal recording medium is pressed against a recording paper 4, an ink layer 1 and a releasable layer 2 are melted, the ink layer 1 is adhered to the paper 4, the releasable layer 2 undergoes cohesive fracture, and, for example, a character 6 including a part of the ink layer 1 and a part of the releasable layer 2 is transferred onto the recording paper 4. In a correcting operation, printing energy is applied to a printing head 5 under the condition where the ink layer 1 faces the character 6, and the thermal recording medium is pressed against the recording paper 4. At this time, the adhesive force of the releasable layer 2 for adhesion to the ink layer 1 and a base layer 3 is higher than the adhesive force between the character 6 and the paper 4, so that the character 6 is adhered to the ink layer 1, and it is released from the paper 4. Accordingly, the thermal recording medium itself can be used for printing and correcting.
