Title: Mold made of concrete having metallic shell and production thereof
Inventor: SAWAIDE MINORU
IPC: B21D26/021
Filed: 1991-12-04
Abstract: PURPOSE:To provide the mold suitable for production of diversified kinds in small quantities. CONSTITUTION:This mold has a metallic shell 3 made of a superplastic metal having a projecting part 2 transferred with the shape of a requested product and a hardened packing material 4 supporting this projecting part 2. An adhesive consisting of a synthetic resin, such as epoxy resin, is packed between the metallic shell 3 and the hardened packing material 4 packed into the recessed part of the metallic shell 3. The metallic shell and the hardened packing material are securely connected by this adhesive. The metallic shell and the hardened packing material are integrally molded and since the superplastic metal is used for the metallic shell, the metallic shell is easily molded to the shape of the product with high accuracy. Since the strength of the metallic shell is increased, the mold having a large shape can be produced and the number of service times of the mold is extended. The molding of the metal as one piece of part is possible and the cost required for the mold is reduced.

Title: Separating device for submerged anchoring body
Inventor: YAMAMOTO YUTAKA
IPC: B63C11/48
Filed: 1993-12-21
Abstract: PURPOSE:To improve safety and to simplify structure by a method wherein when an expandable body is contracted through operation of a hydraulic pressure, an engaging shaft body is raised, engagement between a part to be engaged and an engaging part is brought into a releasable state, an oscillation lever is oscillated through the energizing force of a spring body to release engagement. CONSTITUTION:A safety pin 31 is pulled off and an submerged anchoring body 1 is charged. An engaging shaft body 23 is pressed downward through the stretching force of a bellows 25 is pressed downward. A recessed part 14a for engagement is engaged with a protrusion 23a for engagement of the engaging shaft body 23 to block oscillation of an oscillating lever 12. With the progress of sinking in water, a hydraulic pressure is exerted on a bellows 25 through a communication hole 26. This operation causes contraction of the bellows 25. Thus, the engaging shaft body 23 is raised, the recessed part 14a for engagement and the protrusion part 23 are brought into a disengagement state, and forced holding of the oscillating lever 14 is rendered ineffective. Thus, the oscillating body 16 is protruded in the direction of an arrow mark (a) through the force of a compression spring 18 and the oscillating lever 14 is oscillated in a direction (b) and the recessed part 14a for engagement is separated away from the engaging shaft body 23.

Title: Pll circuit
Inventor: YAMAZAKI SHIGERU
IPC: H03L7/085
Filed: 1990-11-27
Abstract: PURPOSE:To suppress carrier and to reduce jitter while securing a wide capture range by defining the phase compared result of an EOR (exclusive OR) and the result of adding an (n) number of signals, which phase is shifted to the above-mentioned result for 27pi/n, as the output of a phase comparator. CONSTITUTION:A digital signal Sin inputted from an input terminal 1 is inputted to a pi/2 phase shifter 213, and a signal Sb shifting the phase by pi/2 is obtained. Similarly, an output Sv of a VCO 5 is inputted to the pi/2 phase shifter 213 and a signal Sd shifting the phase by pi/2 is obtained. An Se1 comparing the phases of the Sin and the Sv by an EOR 207 is added with an Se2 comparing the phase of the Sb and the Sd outputted from pi/2 phase shifters 213 and 214 by an EOR 208, and an obtained Sp is defined as the output of a phase comparator 2. The amplitude of a carrier becomes 1/2 in comparison with the conventional circuit composed of the EOR only, and the frequency of the carrier is made double. Thus, jitter generated in the output of the VCO 5 can be suppressed.

Title: Compression pipe
Inventor: TROMMER JOERG DIPL ING
IPC: F16F7/12
Filed: 1993-11-29
Abstract: PURPOSE: To accommodate impact energy with small compression force by placing a part press-deformed inward radially, in the axis direction of an upset tube, and by making one base angle of bend at the press-deformed part larger than the other base angle of bend at the press-deformed part. CONSTITUTION: An upset tube 1 is divided into two tube parts 2, 3 by a press- deformed part 4. The press-deformed part 4 has different base angles of bend αand β, and one angle α is larger than the other angle β so as to assure specified fracture. The outer diameter Da3 of one tube part 3 of the upset tube 1 is larger than the inner diameter Di2 of the tube part 2 of the upset tube 1. Therefore, the tube part 3 will be pressed into the tube part 2 after the shearing of the upset tube 1 at a place 5, and a defined amount of friction energy can be destroyed because of the diameter difference. As a result, the upset tube 1 is assured to shear in the case of collision in the region of the larger angle, the base angle of bend α.

Title: Production of zinc oxide whisker
Inventor: YOSHINAKA MINORU
IPC: C30B29/62
Filed: 1988-12-20
Abstract: PURPOSE:To obtain the zinc oxide whiskers of a gigantic tetrapod shape appropriate as a reinforcing material, etc., by adding ceramic powder to metallic zinc powder or the zinc powder coated with an oxide film on the surface, heating the mixture in a oxygen-contg. atmosphere, and oxidizing the mixture. CONSTITUTION:Metallic zinc powder or the zinc powder coated with an oxide film obtained by spraying metallic zinc powder into the air by an arc-type flame spraying device on the surface are prepared. Ceramic powder (e.g. synthetic zeolite and activated alumina) is then added to the zinc powder. The mixture is placed into a heat-resistant vessel, heated at about 700-1300 deg.C in an oxygen-contg. atmosphere, and oxidized. The zinc oxide whiskers of a gigantic tetrapod shape are grown and taken out. Since the obtained zinc oxide whiskers have a three-dimensional structure free of anisotropy, the anisotropy in the mechanical and electrical characteristics is not caused when the whiskers are used as a reinforcing material, an electrical material, etc.

After that, the cutter 22 is moved downward. When the cutter 22 is brought into contact with the roller 20, the cutter 22 is rotated in the opposite direction of the roller 20 to cut the sheet of paper in the vertical direction. A horizontal cutter section H can move a cutter 27 in horizontal (direction B) and vertical directions with respect to a discharge roller 20. When the sheet of paper is cut, the cutter 27 is moved downward to be brought into contact with the roller 20.  When the cutter 27 is brought into contact with the roller 20, the cutter 27 is moved in the right-and-left direction (direction B) to cut the sheet of paper in the horizontal direction.

SOLUTION: A wire mesh (demister) installed in the internal air flow path of an air cooler 1 or the shape of a plate-type moisture separating device 2 is made cylindrical, and the moisture separating device 2 is arranged parallel with the cylindrical body of the air cooler 1. In addition, the moisture separating device 2 is equipped with a lid 2A for closing the upstream side of the device 2, a heat conducting pipe 3, a support plate 4 for the heat conducting pipe 3 and a water chamber 5 for a cooling water flowing into and out of the heat conducting pipe 3. An arrow mark indicates the flows of the air and the cooling water. If it is designed in terms of the same flow rate as that of the cooling water, the air cooler can be made compact and therefore, made less costly.  Further, if it is designed to be of the same size as that of a water cooler, the air cooler will have a decrease in the air pressure loss and an increase in the moisture removing performance. Consequently, it is possible to enhance the performance of an air compressor.
