Title: Diesel engine with auxiliary combustion chamber
Inventor: SATO YOSHIHIKO
IPC: F02B19/14
Filed: 1984-07-31
Abstract: PURPOSE:To shorten the ignition delay as well as suppress rise of cylinder pressure through retarded combustion by furnishing a passage to put the fuel injection nozzle in communication with the aux. combustion chamber, and by installing sub-jet of the fuel injection nozzle in such a way as facing the interior wall of said passage. CONSTITUTION:A passage 4 in the form of a cylinder is provided at a swirl chamber 2, formed in a cylinder head 1, on its side opposite to the main combustion chamber 3. A fuel injection nozzle 5 is provided facing the swirl chamber 2 through said passage 4. This fuel injection nozzle 5 is composed of a body 9 and a needle valve 10 reciprocating inside it, and a main jet 11 and sub-jet 12 are formed at the tip of th nozzle body 9. The sub-jet 12 is inclined outward so as to face the interior wall 4a of the passage 4. This allows the sub-atomization F from the sub-jet 12 to run against said interior wall 4a of the passage 4, and part of it is turned into particles while the rest constitutes a fuel film H spread alongside the interior wall 2a of the swirl chamber 2. Thus the intended purpose is accomplished.

Title: Tube internal surface lining method
Inventor: TAKAGI MASAHARU
IPC: B29C63/00
Filed: 1979-12-07
Abstract: PURPOSE: To apply an internal lining of uniform film thickness free from pin holes at low cost by inserting into a lined tube a tube obtained by laminally adhering the opposite side of a barrier film, and sliding a laminally adhered portion under heating and pressure.  
     CONSTITUTION: A barrier film tube 2 having a smaller external diameter than the internal diameter of a lined tube 3 is formed by laminally adhering the longitudinal opposite sides 11, 12 of a barrier film 1 through the intermediary of a thermoplastic adhesive which softens at lower temperature than the film 1 in such manner that the laminally adhered portion may come externally. Next, the tube 2 is inserted into a tube 3 and heating/pressure are provided through the interior of the tube 2 using steam, etc. The laminally adhered portion smoothly slides without giving an excess tension to the barrier film 1 due to quicker softening than the said film 1, and the internal diameter of the tube 2 is expanded following the reduction of the laminally adhered portion. In addition, a tube internally lined in such manner that the external circumference of the tube 2 is tightly adhered to the internal circumference of the tube 3 with a remaining slight area of the laminally adhered portion 13, is obtained.

Title: Microcomputer
Inventor: SANTSUKO TOSHIYUKI
IPC: G06F1/04
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To make low power consumption while continuing the operation of a specific peripheral circuit when a low power consumption mode is set. SOLUTION: A CPU 4 and peripheral circuits 5 and 6 constituting a microcomputer 1 operate on the basis of a system clock outputted from a 1st oscillation circuit 2. When a low power consumption mode is set to the microcomputer 1 here, the output of the system clock from the circuit 2 is stopped to stop them. On the other hand, since a selector 7 gives a sleep clock (having a lower frequency than the system clock) outputted from a 2nd oscillation circuit 3 to the 2nd circuit 6 that has to operate even in the low power consumption mode, the circuit 6 is made to operate at a low speed so that low power consumption can be made.

IPC: F25J3/02
Filed: 1995-06-27
Abstract: PURPOSE: To improve the efficiency of production by cooling a gaseous mixture composed of O3 and O2 to a first set temp. in nearly an atm. state, cooling this gaseous mixture to a lower second temp. in a hermetic state and discharging the gas up to a set pressure, then raising the temp. to a higher third set temp. CONSTITUTION: About 96mol% of the O3 and about 4mol% of the O2 are formed in a mixed liquid phase when the gaseous mixture composed of, for example, about 5mol% concn. of the O3 and the O2 in a refining vessel is cooled to the first set temp., for example, about 110K, within the first temp. region of 100 to 120K in nearly the atm. state. A large amt. of the O3 and a small amt. of the O2 are liquefied with small energy. The vapor pressure drops down to about 8KPa and the gaseous phase part in the vessel is discharged down to about 0.04KPa vapor pressure while maintaining the temp. when the gaseous mixture is cooled down to the second set temp., for example, about 77.4K, lower than the first set temp. within the second temp. region of 60 to 80K in the hermetic state. The liquid mixture of about 99mol% O3 is thus obtd.  Further, the O3 of nearly 100mol% concn. is obtd. when the gaseous mixture is heated up to the third set temp., for example, 90.2K, higher than the second state temp. within the third temp. region of 90 to 120K while the gas is discharged.
