Title: Kerosene burner
Inventor: SASAKI YASUO
IPC: F23D11/24
Filed: 1989-11-21
Abstract: PURPOSE:To reduce the combustion flame temperature and lower the NOx value by the constitution that part of the combustion gas is drawn through an air passage gap formed with an exhaust gas circulation ring by the injector effect generated by the injection air from a blast port shaped like a nozzle and circulates in the burner cone. CONSTITUTION:A ring 14 for exhaust gas circulation has a burner cone 3, a partition plate 10, and an air passage gap 15 along the wall face of a nozzle- shaped blast port section 12 that is provided at the center of the partition plate, and on the outside of the nozzle-shaped blast port section 12 an air passage port 16 is formed. In the combustion the oil spray from a nozzle 9 is dispersed and burns by the air jetted from a nozzle-shaped blast port 11, an air passage hole 13, and the air hole 6 of the burner cone 3. During this combustion, the combustion gas is sucked through an air blast gap 15 formed on the outside of the nozzle-shaped blast port 11 with a ring 14 for exhaust gas circulation by the injector effect generated by the air jetted from the nozzle-shaped blast port 11, and circulated in the burner cone 3. The temperature of the combustion flame is thereby reduced by the combustion gas circulation and the NOX value is lowered.

Title: Method and device for reading image
Inventor: MIURA HIROSHI
IPC: G03B27/50
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To shorten the entire read time by deciding an exposure at the time of main scanning by image data obtained by performing preliminary scanning and deciding standby time corresponding to light quantity for the main scanning by using a table. SOLUTION: The preliminary scanning is performed by irradiating original images with prescribed low light quantity, a histogram preparation part 11 prepares an image brightness histogram from obtained data and a CPU 8 sets a read parameter optimum for the main scanning based on the histogram. Since the standby time after the CPU 8 sets main scanning light quantity to a lamp power source 7 until the light quantity is stabilized is determined by a difference between the preliminary scanning light quantity and the main scanning light quantity, the start of the main scanning is delayed for the time obtained by the table or a function formula. Thus, the standby time is short when light quantity change is less and the entire read time is shortened. Also, the table or the like is incorporated in a ROM 12 along with other control programs and the number of parts is not increased.

IPC: H05K5/02
Filed: 1999-10-27
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent acoustic characteristic by preventing a waterproof membrane from being elongated more than required or damaged due to an external pressure even when the area of the waterproof membrane is increased. SOLUTION: The waterproof structure consists of a device case 1 where an acoustic through-hole 2 is formed at prescribed part, a waterproof membrane 3 that clogs the through-hole 2 in the device case 1, and a protection member 5 that have porosity to restrict deformation of the waterproof membrane 3 and provided in an inner side of the device case 1 from the waterproof membrane 3.  Thus, in the case that an external pressure such as water pressure and atmospheric pressure is higher than an inner pressure in the device case 1 when the external pressure is applied to the waterproof membrane 3, even if the waterproof membrane 3 is going to be deformed so as to be pushed toward the inside of the device case 1, since the protection member 5 provided in the inside limits deformation of the waterproof membrane 3, even when the area of the waterproof membrane 3 is increased, the waterproof membrane 3 is surely prevented from being elongated more than required or damaged thereby obtaining an excellent acoustic characteristic.

Abstract: PURPOSE:To excellently compensate various aberrations by varying the focal length of the whole system while holding an image plane position constant by moving 1st, 2nd, and 4th lens groups in the direction of the optical axis. CONSTITUTION:This system is so constituted that when the lens groups move from the short-focus side (a) to the long-focus side (b), l1>l1', l2<l2', and l3>l3', where l1 and l1' are the air gap between the 1st lens group L1 and the 2nd lens group L2, l2 and l2' are the air gap between the 2nd lens group L2 and a 3rd lens group L3, and l3 and l3' are the air gap between the 3rd lens group L3 and the 4th lens group L4. The l1>l1' is a condition for constituting a reverse telephoto type on the short-focus side (a) and l2<l2' is a condition for constituting a telephoto type on the long-focus side (b). For the telephoto type on the long-focus side (b), when the lens system is divided roughly into the front group consisting of the 1st and 2nd lens group and the rear group consisting of the 3rd and 4th lens groups, the front group has positive refracting power and the rear group has negative refracting power. Consequently, the aberrations are compensated excellently over the entire focal length range.

IPC: H01H13/712
Filed: 1988-12-01
Abstract: PURPOSE:To enable the easy removal of a mold releasing sheet by laminating the sheet onto a front sheet after the completion of a slit formation process. CONSTITUTION:First, a mold releasing sheet 2 is paid out from a roll 4 and proceeds to a 'slit formation process'. In this process, a slit 3 is formed at the predetermined positions of the sheet 2, using a slit cutter 6. The slit 3 is so formed as to have length larger than the width of a front sheet 1. Before laminating the sheet 2 onto the front sheet 1, the slit 3 is formed on the sheet 2 as aforementioned, thereby preventing the slit cutter 6 from damaging print and adhesive layers on the upper surface of the sheet 1. Furthermore, as the sheet 2 has the slit 3 across the width thereof, it becomes easy to peel off the sheet 2 whenever necessary, simply by folding the sheet 2 at the position of the slit 3.

When plural ridge lines are included, a P symbol as the third classifying symbol is correlated with an element in the set of the eight elements corresponding to the octant. In addition, when only one ridge line, namely only one curved surface, is included, an E symbol as the second classifying symbol is correlated with an element in the set of the eight elements corresponding to the octant.
