Title: Low-nox burner
Inventor: TAKESHITA SHIRO
IPC: F23D14/70
Filed: 1990-09-18
Abstract: PURPOSE:To reduce NOx in the exhaust gas, prevent the flame from causing a backfire to an outlet of a mixture-gas passage so as to improve the durability of the burner, and stabilize the flame so as to reduce the noise by providing a secondary mixture-gas chamber and a metal net on the downstream side of a mixture-gas passage in the secondary mixture-gas chamber. CONSTITUTION:Mixture-gas passages 10 and air-intake ports 16 open passageways leading to a secondary mixture-gas chamber 11 for mixture gas and secondary air. By using metal nets 15, good mixing is promoted between portions of the mixture gas and the secondary air even when the combustion is at its minimum with the flow at low speed; uniform mixture gas with the combustibility below the inflammability limit can be sent to a secondary flame- hole part 14 for the ejection; and the hole diameter can be made smaller than the quenching diameter. Therefore, a flame can be prevented from causing a backfire through the secondary mixture-gas chamber 11 to the outlet of a mixture-gas passage 10. The metal nets 15 have a straightening effect on the flow ejected from the secondary flame-hole part 14 so that the flame is stabilized and the noise during combustion is reduced. Furthermore, by supplying to a flame formed over a primary flame-hole part 9 unburned mixture gas of low oxygen concentration that is ejected from the secondary flame-hole part 14, the combustion reaction can be moderated and through lowering of the flame temperature generation of thermal NOx can be reduced.

IPC: G03F1/00
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To produce a three-dimensional photomask with high accuracy and good durability even on a three-dimensional base body of a complicated shape by forming a temporary mold by using a molding die, forming a light-shielding pattern on the body, and bringing the part where the light-shielding pattern is formed into contact with a molten or softened light-transmitting resin to transfer the light-shielding pattern to the resin. SOLUTION: A temporary mold 3A (or 3B) is formed by using a molding die to form a base body having three-dimensional faces where circuits are to be formed. A light-shielding pattern P according to circuits is formed on the faces of the temporary mold 3A (3B) corresponding to the three-dimensional faces of the base body where the circuits are to be formed.

Title: Method of extracting electronic parts from carrier tape
Inventor: ASAI KOUICHI
IPC: H05K13/00
Filed: 1985-11-06
Abstract: PURPOSE:To prevent electronic parts from jumping out of storage recesses due to shock at the feed start or stop by covering openings of storage recesses of electronic parts with a cover member from the feed start of a carrier tape until electronic parts are absorbed by an adsorbing tool. CONSTITUTION:A carrier tape 20 is advanced with openings of storage recesses 16 of electronic parts being covered by a cover member 86. An adsorbing tool 16 is lowered to this cover member 86 through a notch 118 formed at a width narrower than an electronic part (chip) 24 but wider than the adsorbing tool 116 to adsorb the electronic part 24. Then, the cover member 86 is retreated so as not to cover the electronic part 24 adsorbed by the adsorbing tool 116, and the electronic part 24 is extracted from the electronic part storage recess 16. Accordingly, by covering the carrier tape 20 with the cover member 86, the electronic parts 24 are prevented from jumping out of the storage recesses 16 or changing the attitude due to shock at the feed start or stop, thus an extraction miss of electronic parts can be reliably prevented.

Abstract: PURPOSE:To shift an optical axis easily, and to eliminate the need for high assembly precision and realize high resolution by varying the angle between the normal line of the incidence or projection surface of a glass plate or prism group and the optical axis of an optical system. CONSTITUTION:Light traveling straight near the optical axis is refracted by the incidence surface of the glass plate 2 and further reflected by the projection surface.

Abstract: PURPOSE:To decrease the number of the occurrence of the impossibility of the detection for an address data by recording doubly and assembling the address data including a synchronizing signal and an error detecting code related to them and detecting them in parallel by two error detecting circuits. CONSTITUTION:An address data part is composed of a sector mark (SM) 11 showing the head of the address data part, namely, the head of the sector, a lead-in signal (VFO) 12 synchronizing the clock of the clock reproducing part, two synchronizing signals (STNC 1 and STNC 2) 13 and 13', two address signals (ID) 14 and 14' and error detecting codes (CRC) 15 and 15'. For the method giving the address, the disk is divided in the diameter direction, makes this into the track, divides the inside of the track 1 into prescribed numbers and makes it into the sector. By recording the address data 14 and 14' two times together with the synchronizing signals 13 and 13' and the error detecting codes 15 and 15', the probability that both cannot detect the address data simultaneously by mistake comes to be smaller. Thus, the number of the sector is decreased in which the address cannot be detected.
