Title: Internal-combustion engine with subsidiary combustion chamber
Inventor: HASEGAWA KUNIO
IPC: F02P13/00
Filed: 1977-09-30
Abstract: PURPOSE: To provide an internal-combustion engine with subsidiary combustion chamber, in which ignitability of mixture in the subsidiary combustion chamber, is  improved by disposing th electrode of ignition plug at a position slightly displaced  from the center of the subsidiary combustion chamber toward the exhaust port.  
     CONSTITUTION: Subsidiary combustion chamber 14 is formed at a position slightly displaced from the center of main combustion chamber 4 between suction port 5 and exhaust port 7. The subsidiary combustion chamber 14 is formed with torch holes 17, 18, 19, center lines of which join at a point in the chamber 14 slightly displaced from the center line 12 of subsidiary chamber cup 13 away from the suction and  the exhaust ports 5, 7. At the point in the chamber 14, velocity of fresh mixture  stream is high so that ignitability of mixture is low. However, ignitability in the  chamber 14 is higher at the portion near the exhaust port 7 because of greater  heat transmission, although residual gas tends to be left there. With overall judgement of ignitability in chamber 14 in consideration of various factors, it was found  that ignitability in chamber 14 is highest at the point displaced by distance (e)  from the center line 12 of cup 13 toward the exhaust port 7, and electrode 24 of  ignition plug is placed at the point

Title: Estimation apparatus for temperature of cooling water in engine
Inventor: KUBOTA AKIJIROU
IPC: G01K11/00
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain an estimation apparatus by which the temperature of, cooling water in an engine can be found without installing a sensor. SOLUTION: A control circuit 2 at an ECU 1 for air conditioning control is used also as a temperature estimation means for cooling water. Since the temperature of the cooling water is changed in terms of an exponential function between an estimated final arrival temperature and a present temperature, it is expressed as the function of time. When a change in the state of an engine is detected by the control circuit 2 on the basis of a signal from an EFI, a temperature estimation program is interrupt-executed at a prescribed time interval, and the temperature is estimated. When the engine is stopped, a computing and processing operation is stopped when a computed result agrees nearly with the estimated final arrival temperature, and the power consumption of an estimation apparatus is reduced.

Title: Production of single crystal optical fiber
Inventor: YOKOHAMA ITARU
IPC: G02F1/37
Filed: 1990-05-09
Abstract: PURPOSE:To enhance wavelength converting efficiency by constituting a crystal base material of a crystal core base material having a high refractive index and a crystal clad base material having a low refractive index. CONSTITUTION:The crystal core base material 21 consisting of LiNbO3 added with 2% MgO is immersed in a melt 23 for the crystal clad base material consisting of LiNbO3 added with 5% Mg. While the crystal clad base material 22 is stuck to the crystal core base material 21, the base material is pulled up and solidified. The base material is worked and shaped at need to form the crystal base material 24. The Mg added to the LiNbO3 decreases the refractive index of the LiNbO3 in nearly proportional to the amt. of the added Mg. The refractive indices of the crystal core base material part 21 and the crystal clad base material part 22 varying in the amt. of the added Mg are, therefore, higher with the crystal core base material part 21. The wavelength converting efficiency is improved in this way.

Surfaces E and F are connected by means of sloping surface G. By sloping surface G, the occurence of eddy currents in the air flow along partitioning plate 41 is prevented and thereby flow resistance is reduced. Also, since distance D 2  between surface F of partitioning plate 41 and front panel 7 is made larger than distance D 1  beteeen surface E and front panel 7, the flow resistance in the passage mainly formed by surface F and front panel 7 is made smaller compared with that in the passage mainly formed by surface E and front panel 7
