Filed: 1987-10-06
Abstract: PURPOSE:To obtain a sharp vertical magnetic field even with a single-side access type magnetic head by providing an inductive magnetic path consisting of a superconductive material for the magnetic head. CONSTITUTION:The magnetic head consists of a magnetic core 10 composed of a soft magnetic material, a coil 11 to excite the magnetic core 10, and the inductive magnetic path 16 composed of superconductive materials 15a and 15b to guide a magnetic flux generated at the magnetic core 10 part in an arbitrary direction. Further, the magnetic core 10 consisting of the soft magnetic member and the coil 11 to excite the magnetic core 10 generate the magnetic flux corresponding to a signal current in the magnetic core 10. In addition, the inductive magnetic path 16 consisting of the superconductive members 15a and 15b completely prevents the magnetic flux generated at the magnetic core 10 from leaking in an unnecessary direction with a Meissner effect (complete diamagnetism), which consists the characteristics of superconductive member, and operates so that it may be concentrated to a necessary part. Thus, when the magnetic head of a vertical magnetic recording system is applied, the sharp magnetic flux in the vertical direction in respect to a recording medium 13 surface can be obtained.

SOLUTION: After a slope protection drainage material mixes main body fibers with binder fibers, thereby forming a web, a binder component of the binder fibers is molten by way of a heat treatment device, thereby forming a fiber block bonded with the fibers comprising the main body. Then, when the slope protection drainage material 1 is used as a slope protection drainage material 1, the thickness of the material is set to 10mm and over so as to prevent a filling material from being broken by an earth pressure and blowing out. Then, the bulky density of the slope protection drainage material 1 is specified to range from 0.15 to 0.6g/cm<3> but when the bulky density fails to satisfy the aforesaid value which ranges from 0.15 to 0.6g/cm<3> , the material can be easily broken down and it is improper.  The water permeable coefficient of the slope protection drainage material is specified to be at least 1×10<-3> cm/sec. If the value is less than 1×10<-3> cm/sec, the drainage effect is small as the slope protection drainage material.

Title: Picture reader
Inventor: OGUCHI HIDEYUKI
IPC: H04N5/335
Filed: 1988-10-05
Abstract: PURPOSE:To prevent density deterioration due to light bypassing to a dark part in an edge part with a large brightness density difference by providing an optical absorbing member in the very vicinity of or in contact with the surface of an optical window glass so as to avoid the light incidence to a part other than the photodetection face. CONSTITUTION:A frosting and insulating black paint member 101 is applied or printed onto the surface (except the upper side of the photodetection face) of an optical window glass 2. Thus, since the light having being incident in the face of a photodetector mask 42 in a conventional device is absorbed by the paint member 101, the scattering is prevented. Since the direct incident light is surely made to the photodetection face 43, the size of the part 101a not applied with black paining is slightly larger thant the size of the photodetecting face 43. Thus, the generation of contour of the edge part is suppressed and a picture with high density resolution and sharpness is obtained.

Title: Electric pin
Inventor: SASAKI SHIGERU
IPC: H01R43/16
Filed: 1989-09-29
Abstract: PURPOSE:To eliminate the occurrence of a crack in solder and a ceramic substrate by sticking a high conductive body layer having sufficient thickness on the circumference of a core material except a pin part and also the tip part of a head part formed with a material having a low thermal expansion coefficient. CONSTITUTION:A material having a low thermal expansion coefficient is used as the core material 16 of a pin part 12 and the head part 14, and a high conductive body layer 18 having sufficient thickness is stack on the circumference of the core material 16 except the tip part 14a of a head part 14. When an electric pin 10 is soldered on a ceramic substrate 26, the thermal expansion coefficient of a whole head part 14 becomes considerably lower than that of copper itself since the head part 14 is formed with a cover layer 16 and a copper layer 18. This causes tensile stress generated during the cooling of solder 24 to be small to prevent the occurrence of cracks in solder and a ceramic substrate.

IPC: H01L21/8238
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for a semiconductor device containing an MOS transistor, wherein a manufacturing process can be simplified. SOLUTION: When a gate electrode pattern is drawn on an SOG film (resist film) 49, an ion beam is emitted with Pt-B as the ion source. Drawing of the gate electrode pattern on the resist film 49 and formation of a channel area 47 are performed at the same time. Since the SOG film (resist film) 49 changes when irradiated with the ion beam, from the SOG into an SiO2 film 49a, the pattern of the SiO2 film 49a is developed with butanol and washed in pure water only for the SiO2 film 49a to remain, thus the SOG film (resist film) 49 is removed. Then, by etching a gate electrode film 48 with the SiO2 film 49a as a mask, the gate electrode film 48 which is not covered with the SiO2 film 49a is removed. By removing the SiO2 film 49a, a gate electrode is formed.
