Title: Fuel injection nozzle
Inventor: HERUMUUTO RENBORUTO
IPC: F02M45/08
Filed: 1990-11-14
Abstract: PURPOSE: To provide a satisfactory engine operating characteristic by designing the stopper shoulder of a nozzle main body to be as narrow as possible, and designing the radial overlap of the stopper shoulder by the closing head of a valve needle to be also as small as possible. CONSTITUTION: When a force exceeding the difference in spring force between a closing spring 24 and a pressure spring 70 is applied to a valve needle 18, the needle 18 and a valve sleeve 34 are together shifted downward, in which case a jet of fuel is first ejected via nozzle holes 86, 88 into a combustion chamber in the predetermined direction. When a valve seat 26 (stopper shoulder) makes contact with a closing head 20, the overlap (c) of the valve seat 26 is made slight so that the converged jet is not deflected when passing through an annular gap between the valve seat 26 and the heat 20. The needle 18 advances, and after the valve sleeve 34 has abutted against a bottom 44, the sleeve 34 is delayed by the needle 18, in which case the space between a lower edge 72 and a valve seat surface 22 is opened while a main fuel quantity ejected at high pressure reaches the inside of the combustion chamber in the form of a bevel jet.

IPC: B41N1/24
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To securely prevent the transfer of cream solder forming a cause of defects of iron bonding on a pad of a base. SOLUTION: Rands 2 for soldering chips, a rand 3 for bonding bar chips and a pad 4 for connecting wires of wire bonding are formed on the upper face of a base 1.

Title: Magneto-resistance effect type magnetic head
Inventor: TANABE HIDEO
IPC: G11B5/39
Filed: 1988-12-07
Abstract: PURPOSE:To respectively impress bias magnetic fields opposite in direction upon each channel of magnetism sensible sections so as to differentiate the output voltage of each magnetism sensible section by magnetizing two rectangular permanent magnet films having different coercive forces in opposite directions. CONSTITUTION:Permanent magnet films 31 and 32 are magnetized by impressing a DC magnetic field higher than the coercive force of the films 31, namely, higher coercive force of the films 31 and 32. Then only the film 32 is again magnetized in the opposite direction by impressing a DC magnetic field which is lower than the coercive force of the film 31, but higher than that of the films 32, namely, lower coercive force of the films 31 and 32. Accordingly, bias magnetic fields of opposite directions are impressed upon the magneto- resistance effect films 5 of each channel from the permanent magnet films magnetized in the opposite directions. Therefore, outputs of the magneto- resistance effect films 5 of each channel can be differentiated.

Filed: 1990-11-14
Abstract: PURPOSE:To enable controlling the air volume and prevent turbulence, etc., of the flow by a method wherein a plurality of high-density air filters in plate form are set in a row along the flow of air in a duct, and varying the number. CONSTITUTION:A plurality of air filters-in-plate-form 11 are set in a row in the direction of the flow of air, a first such filter 11 being set contiguously behind a fixed spacer 12a and, after placing a detachable spacer 12b contiguously downstream, a second such filter 11 being set and so forth in succession. The resistance which affects a flow of air varies with the number of the air filters-in-plate-form 11 in use. Therefore, the control of the air volume can be effected by changing the number of such air filters 11 set for use. This method of controlling a flow of air serves to improve a flow of air in preventing turbulence, etc., through smoothening of the flow and in reducing whistle and whiz of flowing air.

Title: Multifunctional copying machine
Inventor: KAWAI YOSHIHISA
IPC: G06K15/12
Filed: 1988-12-06
Abstract: PURPOSE:To improve operability by interrupting the currently executed mode and preferentially selecting an image writing mode when the image writing mode is selected although the other mode is currently executed. CONSTITUTION:In the multifuntional copying machine, the mode setting part of a general system controller 101 includes an image write remote mode, the image writing mode, an image reading mode, a digital copying mode, and an analog copying mode. Under this constitution, if the other mode is currently executed when a mode selecting means selects the image writing mode, a mode selection control means interrupts the currently executed mode to preferentially select the image writing mode. The functions of the multifunctional copying machine include ones to be preferentially executed rather than the others, and ones that can be executed simultaneously. Consequently, by prioritizing the functional modes, service efficiency can be improved.

The compound is stable under the presence of contaminants, such as chlorine atoms and calcium atoms in the aqueous system and also to the chemical attack from the system itself and ultraviolet rays and does not give any corrosive attack to the materials constituting the system. When a water treating agent added to the aqueous system is an effective component, the compound expressed by formula I can coexist with chlorine, bromine, and calcium ions existing in the water and also with an effective organic or inorganic water treating component, for example, the corrosion inhibitor and scale preventing agent. Therefore, this compound can be suitably used for detecting the concentration of an effective component in industrial water.

Title: Alkaline battery
Inventor: YAMASHITA KATSUHIRO
IPC: H01M2/16
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent sudden generation of gas in large quantities due to short circuiting of battery. SOLUTION: An alkaline battery comprizes a hollow tubular positive electrode active material 6 filled within a bottomed tubular positive electrode can 4 along an inner circumferential surface of the positive electrode can 4, a separator 8 mounted on an inside surface of the positive electrode active material 6, and a negative electrode active material 10 filled inside the separator 8. A lower end opening part 8a of the separator 8 is closed with an insulation material 30 and therefore the negative electrode active material 10 and an inner bottom surface 4a of the positive electrode can 4 are isolated from each other.  This insulation material, comprizing a heat contraction material, contracts along radial directions of the positive electrode can 4 due to heat generated by short circuiting when the battery is externally short-circuited and releases the lower end opening part 8a of the separator 8. The positive electrode active material 6 and the negative electrode active material 10 are thereby short- circuited via the positive electrode can 4, and a short-circuited state continues within the battery even if external terminals are released from the short circuit and sudden generation of gas in large quantities can be prevented.

Title: Semiconductor laser element
Inventor: MATSUBARA KUNIO
IPC: H01S5/00
Filed: 1994-12-14
Abstract: PURPOSE: To prevent the diffusion of high-concentration dopants of a current constriction layer and to form a p-n junction for current constriction, by providing a GaAs oxide layer between a second clad layer and the current constriction layer. CONSTITUTION: A GaAs oxide layer 51 is provided between a second clad layer 4 and a current constriction layer 6. Since this GaAs layer 51 provided on the surface of a cap layer 5 has a crystal structure like an amorphous structure, periodic crystal intervals are disturbed and it is difficult for dopants to diffuse, and the diffusion of dopants into the current constriction layer 6 is suppressed. Since the cap layer 5 is thin its conductivity type is changed by the influence of the diffusion, the conductivity type of the second clad layer 4 is maintained. Besides, the dopants in the current constriction layer 6 can be maintained at a specified concentration. As a result, a p-n junction is formed in the vicinity of the cap layer 5 inside the second clad layer 4, and current constriction is performed normally. In this way, the position of the p-n junction is stable, so it becomes possible to manufacture LD elements with a high yield rate.
