IPC: H01L31/107
Filed: 1993-12-22
Abstract: PURPOSE:To improve the photoelectric characteristic and the carrier running property of a carrier multiplication layer in the wide region of an optical forbidden band width by a method wherein the dilution rate of a dilution gas with reference to the sum of raw material gases which contain Si and an addi tive element is changed so as to correspond to the optical forbidden band width. CONSTITUTION:An optical absorption layer 104 and a carrier multiplication layer 103 are sandwiched between a p-type semiconductor layer 105 which is to be used as a change-injection blocking layer and an n-type semiconductor layer 102. The carrier multiplication layer 103 is constituted of three forbidden band width inclination layers 111, 112, 113. The optical absorption layer 104 and the carrier multiplication layer 103 are formed by means of a plasma CVD apparatus. That is to say, in order to form the difference in level of a forbidden band width which causes carrier multiplication, the ratio of the flow rate of a gas is changed while an electric discharge is being maintained, the gas is then diluted and adjusted by H2 gas, and the forbidden band width is changed. The process is repeated, the forbidden band width inclination layers 112, 113 which are the same as the forbidden band width inclination layer 111 are manufactured, and the carrier multiplication layer 103 is completed.

Title: Needle valve
Inventor: TOUDOUEN HIDEKI
IPC: F16K31/50
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To vary an increasing rate of a flow amount at the time of valve opening without forming a stepped portion on a tapered surface of a needle, and facilitate manufacture by forming unequal pitches on a male screw thread of a lead screw so as to gradually increase a lifting rate every unit rotation at the time of valve opening. SOLUTION: Unequal pitches are formed on a male screw thread 17 formed on an outer peripheral surface of a male screw 16 so as to increase a lifting rate of a needle 22 is gradually increased every unit rotation at the time of opening a valve. When current is carried to coils 6, 7 and a stepping motor 5 is driven, a rotor 8, a rotary member 10 and a steel ball 11 are rotated in one direction. Since the steel ball 11 is slidably engaged with the male screw thread 17, torque is converted to linear motion by a lead screw 13 for starting opening valve. It is thus possible to attain flow rate charactersitics where an increasing rate of a flow amount is gradually increased. Since a tilting angle of a tapered surface 22d of the needle 22 is evenly set, manufacture is facilitated.

Title: Magnetic head and magnetic recorder using it
Inventor: KITADA MASAHIRO
IPC: G11B5/31
Filed: 1993-12-24
Abstract: PURPOSE:To obtain a magnetic head which makes possible a magnetic recording of a high density with a track width below a specified value by using a substrate with a ruggedness to regulate the track width, the height of an element and a magnetic gap with the ruggedness. CONSTITUTION:Leaked magnetic field from a recording medium is drawn with a magnetoresistance film 4 formed on a substrate protruded part 16 while being drawn slightly with the magnetoresistance film 4 at an inclined part other than the protruded part 16 and hence, it becomes negligible because of an azimuth effect. A track width of a reproduction head is confined to the flat part of the magnetoresistance film 4 formed on the protruded part 16. The length of the flat part of the protruded part 16 can be reduced to the minimum + mm by the working of a substrate 1. Even when the flat part of the protruded part 16 is eliminated and the protruded part 16 is made triangular in the shape of the cross section, a shield film 2 with an infinitive thickness or the like exists as ground of the magnetoresistance film 4 to allow the holding of the flat part of the magnetoresistance film 4 infinitively. The magnetoresistance film 4 thus formed minimizes the distortion of a magnetoresistance response curve attributed to a magnetic distortion, thereby suppressing the generation of noises.
