The round pipe 41 is formed to be a pipe elliptical in section. The round pipe 41 is reduced in diameter by draw-machining. Both ends of the bent and machined pipe are joined to each other by welding. A hoop 45 is housed in the cavity of a blow-formed metallic mold 10, heated to a temperature more than a softening point by a furnace 20 and, then, sending a pressure fluid, blow-forging is performed. Thus, by warm blow-forging, a door attaching frame is manufactured.

Title: Data processor for prefetch of instruction
Inventor: MORISADA TAKESHI
IPC: G06F9/38
Filed: 1986-12-10
Abstract: PURPOSE:To prevent the useless prefetch of instructions by storing previously the change histories of past branching destination address into a branch history table and controlling the instruction prefetching frequency based on the stored past change histories. CONSTITUTION:When an instruction is prefetched, the address of the relevant instruction is sent to an instruction address register 2. While a branch history table 3 transmits each information by means of an instruction address stored in the register 2. A branch destination address 5 receives an estimated branching destination address and an address change register 6 receives the information showing whether a branching destination address is changed in the past or not. An instruction prefetch control device 1 received a coincident state from a comparator 4 and starts the prefetch of instruction of an estimated branch address via an estimated branching destination address. When it is known by the register 6 that a branching destination address is changed in the past, the device 1 finishes the prefetch of instruction in the frequency less than the normal frequency.

Filed: 1990-11-02
Abstract: PURPOSE:To obtain the subject agent capable of applying a nontacky film to dentures by directly adding polymer solid powder prepared by polymerizing tetrafluoroethylene according to a specific method without separating thereof from a dispersion and blending the resultant dispersion in a photo-setting resin, a photoinitiator and a solvent. CONSTITUTION:A coating agent containing a photo-setting resin, a photoinitiator, a solvent and dispersed fine powdery polytetrafluoroethylene is produced. Tetrafluoroethylene is polymerized in the presence of a radical polymerization initiator in a fluorine-based organic solvent to produce a fine powdery polymer dispersion. The resultant dispersion is added and blended in the photo-setting resin, photoinitiator and solvent without separating polymer solid powder. The aforementioned dispersion is more preferably added to a solution containing an organic solvent having a higher boiling point than that of the fluorine-based organic solvent, which is then substantially volatilized and removed. The obtained dispersion is subsequently blended with the aforementioned ingredients. Dentures coated with the above-mentioned coating agent are capable of preventing sticking to rice cakes, chewing gums, etc.

Abstract: PURPOSE:To improve the washing performance by providing a nozzle axis which is floated up, supported in a vertical direction with a nozzle bearing and rotated at the time of operation of a washing pump, and also, stands still on the upper face of a discharging port at the time of stopping the washing pump, on an arm nozzle, and moreover, providing plural pieces of projections on one of the lower end face of the nozzle axis and the upper face of the discharging port corresponding thereto. CONSTITUTION:As for an arm nozzle 20, a nozzle axis 30 is formed in the center part, and it is movable upward/downward in the inside of a nozzle bearing 32 fixed to a discharge port 31 of washing water. In such a state, when a washing pump 19 operates and discharging pressure is generated, the arm nozzle 20 is lifted by upward hydraulic pressure, and the nozzle bearing 32 and the nozzle axis 30 rotate, while sliding. In this regard, the clearance of the nozzle bearing 32 and the nozzle axis 30 is taken larger enough than the open hole of a filer 21, and it can be prevented that fine sand, a sesame, etc., are intruded and a rotation failure occurs. After washing is ended, the arm nozzle 20 stands still by plural pieces of projections 33 of the lower end face of the nozzle axis 30 on the upper face of the discharging port 31, therefore, even if it is left in a state that contamination of high viscosity adheres thereto, it does not occur that the arm nozzle 20 is fixed to the discharge port 31 and the rotation failure is generated.

CONSTITUTION:When the power is varied from the wide-angle side to the telephoto side, the respective groups are moved to an object side so that the gaps among the groups G1-G3 become small; and the 2nd lens group G2 moves nonlinearly to the 1st lens group G1 and 3rd lens group G3 to have a correcting function for the image plane position. Then, the focal lengths of the 1st-3rd lens groups G1-G3 are denoted as f1-f3, the composite focal length of the whole system at the wide-angle end is denoted as fw, and the composite focal length of the whole system at the telephoto end is denoted as fT. In this case, 0.6<f1/fw<2.5, 0.1<f1/f2<1.0, and 0.2<¦f3¦/fT<1.0 hold. Consequently, the zoom lens is obtained which has a wide power variation area up to a >=X2 zoom ratio although the size is small and also maintains superior image forming performance.

IPC: H01L33/62
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To improve light take out efficiency by suppressing total reflection on the interface between a semiconductor light emitting element and a body covering it. SOLUTION: Light transmitting bodies 12, 21 covering the semiconductor light emitting element 5 of a semiconductor light emitting device contain a phosphor 22 being excited by absorbing at least a part of light emitted from the light emitting element 5 to emit light having a different wavelength wherein the emission layer 5d of the semiconductor light emitting element 5 and the phosphor 22 comprise a compound semiconductor of substantially identical composition. Since the light transmitting bodies 12, 21 contain the phosphor 22 having a refractive index substantially identical to that of the emission layer 5d of the semiconductor light emitting element 5, the light transmitting bodies 12, 21 can be constituted entirely to have a refractive index close to that of the emission layer 5d. Consequently, the critical incident angle θc of total reflection can be increased and reflection of light emitted from the light emitting element 5 can be suppressed significantly on the interface to the light transmitting bodies 12, 21.
