Filed: 1991-04-19
Abstract: PURPOSE:To constitute two-group zoom lens so as to be focused on the whole wide photographing range. CONSTITUTION:A positive pregroup I and a negative post-group II are successively arranged from the object side (the synthesized focal distance of the whole system on the wide end is fW). Power variation is executed by changing an interval between the pregroup I and the post-group II. The pregroup I is constituted of the 1st lens group Ia (the synthetic power of the 1st lens group is phiIa) and the succeeding 2nd lens group IIb. Provided that ¦phiIa¦<0.5/fW. The characteristics of an image face are changed by moving the 1st lens group Ia in the optical axis direction.

Title: Electronically controlled fuel injection process and equipment in internal combustion engine
Inventor: KOBAYASHI NOBUYUKI
IPC: F02D41/34
Filed: 1981-07-24
Abstract: PURPOSE:To improve accelerating performance in such a way that in a structure that fuel is synchronously injected to the driving condition, and asynchronous injection is done at the determined time, the asynchronous injection rate is gradually increased by means of the speed in the acceleration which is found out from the generating intervals of accelerating signals. CONSTITUTION:During ordinary operation, an electronic control circuit 38 computes the  reference injection time Tp through each output from an air-flow meter 12 and a distributor 14, and the effective synchronous injection time gammal is computed by compensating  said time Tp in response to signals from other various sensors 16, 22, etc. Besides, an  injection valve 36 is controlled by computing the synchronous injection time gammas in such  a way that the unavailable injection time gammav which is found out when the battery voltage is abated is added to the stated time gammal. Hereat, the control circuit 38 also makes  asynchronous injection to perform fuel injection just directly after signals from the sensors come in to the running condition, but in this case, it is constituted so that speed in  the acceleration is discriminated by means of the generating intervals of the accelerating signals, by which the asynchronous injection rate when accelerating can be gradually increased.

Abstract: PURPOSE: To drain water stagnating in the vicinity of the outside periphery of a runner at each stage and thereby enable an idling operation to be conducted for a long period of time, by providing drain valves for leakage water in a leakage water drain pipe which connects a lower cover for a high pressure stage runner and the upper wall of a return passage ring.  
     CONSTITUTION: The lower cover 8, 17 for the high pressure stage runner 2 and the upper wall of the return passage ring 19 are connected to each other by the leakage water drain pipe 30, in which the drain valves 24, 31 are provided. Each of the drain valves 24, 31 is designed to open a valve port 26 by depressing a valve rod 28 downward when a hydraulic pressure so high as to overcome the force of a spring 29 is applied to the head part 28b of the valve rod 28. When water leaked out from movable guide vanes 10 and the cooling water supplied to a sealing part for the runner 2 stagnate in the outside peripheral area of the runner 2, the pressure of the stagnating water opens the valve 24, is discharged into the passages between return vanes 19a of the ring 19 through the drain pipe 23, flows through a passage 22 and flows into a low pressure stage runner chamber 6 via the passages between stay vanes 15. The leakage water then stagnates at the periphery of the runner 3, from which it is drained to the exterior through the drain pipe 30.

Abstract: PURPOSE:To reduce the scatter of a harmful fluorine component and to produce glass under excellent productivity in case of melting and producing glass contg. a fluorine compd. by using a burner made of a specified metallic material and melting a raw material of glass by high-temp combustion flame due to fuel and gaseous oxygen in a melting furnace. CONSTITUTION:In case of melting and refining a raw material of glass such a frit contg. an F compd., a raw material of glass contg. the F compd. is introduced in a furnace through an introduction port 2 by means of a batch changer 5 provided to the melting furnace 1. High-temp combustion flame at about 2,000 deg.C is blown to the raw material of glass through a water-cooling oxygen burner 7 provided to the position opposite to this raw material to melt it and frit glass is refined and taken out as melted glass through a discharge port 4. In this case, since the oxygen burner is used, exhaust gas is reduced by N2 content in comparison with an air burner, and the blowing pressure is made small and therefore the amount of F compd. to be scattered to the outside of the furnace is reduced. Further corrosion and wear due to F are reduced by forming the drum part of the burner 7 facing the inside of the furnace by means of Cu, Ni, Mo, W and alloy thereof, and the furnace can be used for a long period and operating efficiency is enhanced.

Title: Semiconductor laser device
Inventor: SHIMIZU YUUICHI
IPC: H01S5/00
Filed: 1983-06-29
Abstract: PURPOSE:To oscillate a semiconductor laser device in a low noise with a stable light output by enhancing the reflectivity of two resonator ends higher than that of the end of a semiconductor crystal material itself. CONSTITUTION:The reflectivity of a light in an oscillating wavelength of two resonator ends are enhanced larger than that of a semiconductor crystal itself of a laser medium, and smaller than that of 100 percent. Since the reflectivity of the resonator end is high in such a structure, the ratio of the returning light of the light itself into the resonator is decreased, and since the reflectivity is high, the light energy stored therein is hardly affected by the influence of the light incident from the exterior, thereby obtaining stable oscillated state. Further, since the reflectivity of the both ends is smaller than 100%, the lights can be produced from both side ends.

Abstract: PROBLEM TO BE SOLVED: To reduce the disturbance of sound pressure frequency characteristics caused by a dust cap without remarkable cost-up or sound pressure down. SOLUTION: A discontinuous part 10 to discontinuously change a curvature on cross-sectional shape is formed inside the part of a dust cap 9 fixed with a diaphragm 8. The resonance mode of the dust cap 9 is dispersed without being concentrated to one frequency by the discontinuous part 10 and a resonance peak level is reduced as well. As a result, the disturbance of the overall sound pressure characteristics caused by the resonance of the dust cap can be remarkably reduced. Further, since it is not necessary to use the high internal loss member of heavy weight, sound pressure drop can be prevented.
