Title: Manufacture of high-purity titanium carbide
Inventor: HASEGAWA TAKASHI
IPC: C01B31/30
Filed: 1983-02-10
Abstract: PURPOSE:To obtain high-purity titanium carbide having an excellent mechanical property to be used as a starting material for cutting by mixing titanium carbide obtained from the reaction of titanium halide with carbon, with titanium oxide and carbon and heating the mixture. CONSTITUTION:Titanium carbide obtained from the reaction of titanium halide with carbon is mixed with titanium oxide and carbon and heated. The molal composition ratio of TiO2 to a carbonaceous material such as artificial graphite or carbon black is regulated to 1:3. The composition ratio of TiO2+3C to raw TiC is regulated preferably at maximum to about 50% of the total reaction system to manufacture a high-grade TiC (<=0.1wt% free carbon, oxygen) as a starting material for cutting tools, even if the reaction proceeds sufficiently when the above-mentioned ratio is 80%. With >= about 40% composition ratio of TiO2+3C to the total, the concn. of free carbon and oxygen have a tendency to increase, but titanium carbide to be used sufficiently for manufacturing cutting tools can be obtained even with 60% composition ratio.

IPC: F25B30/02
Filed: 1984-02-06
Abstract: PURPOSE:To obtain high-temperature hot water by preventing the mixing of hot water with supplied water in a hot water storage tank by a method in which only during a given time period when the load of hot water supply is small, a circulating pump and a heat pump are operated for heating operations.

Title: Synchronizing signal generator
Inventor: TOGASHI AKIRA
IPC: H04N5/10
Filed: 1990-01-30
Abstract: PURPOSE:To prevent generation of noise and to improve a pattern by counting an interval of a vertical synchronizing signal in the unit of 1H and applying field discrimination of the vertical synchronizing signal inputted externally based on the count so as to reset or preset a vertical counter. CONSTITUTION:A horizontal synchronization counter 14 frequency-divides a frequency input of nXfH of an original oscillator to 1/n and outputs a horizontal synchronization frequency fH. In this state, when a vertical synchronizing signal is inputted externally to a detector 16, the signal is converted into the vertical synchronizing signal synchronously with the frequency fH and outputted. Then the interval of the vertical synchronizing signals synchronously with the frequency fH is counted by a counter 17 operated by the frequency fH and the field discrimination is implemented by a field discrimination section 18. From the result of discrimination, a gate circuit 19 is controlled to reset a vertical synchronization counter 15. Thus, a counter giving adverse effect onto noise to at least effective video period is excluded from a synchronizing signal generator.

Filed: 1980-02-21
Abstract: PURPOSE: To grind a worked piece precisely and efficiently by a method wherein an injection pressure controlling mechanism capable of changing the injection pressure  of a grinding material is provided.  
     CONSTITUTION: A trimming of a chip condenser 4 is started by opening an injection stop valve 5 leaving a high pressure air supplied from a high pressure supply pipe 11a induced in a mixing chamber with an exhaust stop valve 16 remaining closed. Thus, since the grinding material 10 is injected in a high pressure with the use of the highly pressurized air, the condenser 4 is ground in high speed. On the other hand, a grinding control circuit 7 makes the injection stop valve 5 be closed a little before the yield of an oscillation circuit measured by a yield sensor 8 becomes a prescribed yield, and at the same time, a change-over valve 14 is changed over induce a low pressure air supplied from a low pressure air supply pipe 11b into the mixing chamber 12. Thus, the grinding is carried out in low speed with a low injection pressure.

Title: Power unit using secondary battery pack
Inventor: ISSHIKI MASANORI
IPC: H01M2/10
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To charge a secondary battery quickly without missing any safety through a constant-current intermittent charging, by setting a longer predetermined dead time than the intermittent on-time of the constant-current intermittent charging to a voltage sensing performed in a protection circuit for inhibiting the charging when the terminal voltage of the secondary battery exceeds a charge inhibiting voltage. SOLUTION: In a voltage sensing circuit 14 of a protection circuit 12 of a battery pack 10, a dead-time setting circuit 15 is provided to set this dead time to a longer time than the intermittent on-time of a constant-current intermittent charging. Further, in the initial term of the charging, a continuous constant-current charging is performed by a control circuit 27 of a charger 20 via a constant-current circuit 22 and a switching circuit 23.
