Abstract: PURPOSE:To produce a cutting tool made of high speed steel coated with thin boron nitride film having superior cutting property and tool life by implanting nitride ions in the surface of a base material made of high speed steel, vapor-depositing a boron-containing material onto above surface, and then irradiating the surface with nitride ions. CONSTITUTION:In a vacuum vessel (not shown in fig.), nitrogen gas is ionized and accelerated by means of an ion source 3, and the resulting nitride ions are implanted in a base material 2 made of high speed steel. It is desirable to regulate the implantation energy of the nitride ion s and the amount of the nitride ions implanted to 500eV-40eV and 1X10<14>-1X10<16>pieces/cm<2>, respectively. Subsequently, a vapor deposition material 5 consisting of boron-containing compound or boron as simple substance is vapor-deposited onto the surface of the above base material 2 by means of an evaporation source 4. Simultaneously or alternately with the above vapor deposition, the above surface is irradiated with ion species containing nitride ions by means of the ion source 3. By this method, the surface of the high speed steel base material 2 is nitrided to increase hardness and also a thin boron nitride film containing c-BN is formed with high adhesive strength, by which the cutting tool made of high speed steel coated with thin boron nitride film extremely excellent in cutting property and tool life can be obtained.

Title: Dll circuit
Inventor: HATTORI NORIHIRO
IPC: H04B1/707
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To improve the quality of a demodulated signal by expressing a signal to be the sum of a phase difference component parallel with an I axis and a noise component of which phase is rotated with the lapse of time as a vector provided with the component parallel with the I axis and a component parallel with a Q axis, averaging the signal to reduce only the noise component and outputting the noise-reduced signal as a phase control signal. SOLUTION: A reverse modulation circuit 17 outputs a signal expressing a phase difference to be the sum of a real phase difference component parallel with the I axis and a noise component of which phase is rotated with the lapse of time as a vector provided with the component parallel with the I axis and a component parallel with the Q axis. An averaging circuit 6 averages the vector signal and cancels only the noise component to obtain a signal close to the real phase difference and a diffusion code generating circuit 7 generates a diffusion code based on the obtained signal. A delay 8 delays only a specific period corresponding to one bit of the diffusion code and a delay 9 delays the signal only by the same period and outputs the delayed signal to a correlator 1.  Consequently the generation of jitter can be suppressed and the quality of a demodulated signal-outputted from a judging circuit 14 can be improved.

Title: Production of molding sand for hot box
Inventor: IKEOKA YOSHIRO
IPC: B22C1/02
Filed: 1988-09-19
Abstract: PURPOSE:To prevent the early deterioration and to reduce the amt. of a caking agent to be added by mixing a silane coupling agent into hardening water, kneading the mixture with refractory sand, kneading the mixture with the caking agent, and using the product as the molding sand for a hot box. CONSTITUTION:Ammonium chloride and urea are dissolved in water to obtain hardening water, a silane coupling agent is added to the hardening water by 0.001-0.02wt.% based on quartz sand and mixed, and then the mixture is kneaded with quartz sand. A furan-based resin is added to the kneaded material by 1-3wt.% as the caking agent to form molding sand. When the silane coupling agent alone is kneaded with quartz sand, the sand is unevenly adhered. However, the sand is evenly adhered, because the sand is extended with the hardening water. The early ageing caused when the caking agent and silane coupling agent are simultaneously kneaded with quartz sand can be prevented, and the amt. of the caking agent to be added is reduced.

Title: Die
Inventor: KITAMURA AKIHIRO
IPC: B22C9/06
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To reduce a production cost by dividing a die to plural blocks and making a block exchangeable with an other block. SOLUTION: A die is divided e.g. into blocks 1-12 of 12 pieces. By connecting lower sides of respective blocks 1-12 with adjacent blocks 1-12 with bolts, an integrated die is obtained. When producing a product having a shape different partly, for example, by exchanging the block 1 with the block having another shape, the die is formed. Its cost is greatly reduced as compared to one body die production. When a part of the die is damaged, the damaged block only is exchanged with the block having the same shape, the die is repaired. A repair cost is greatly reduced as compared to a case that the whole die is reproduced. In producing a large-sized die, a material and a working machine of a large size are not required, the production cost is reduced as greatly compared to one body die production.
