Title: Production of magnetic head
Inventor: SATO TAKAHIRO
IPC: G11B5/127
Filed: 1987-12-21
Abstract: PURPOSE:To shorten the lead time of a production and to improve a reliability by regulating a fusion temperature and the atmosphere at the time of fusing when a magnetic block consisting of two faces having at least one face of the metal magnetic film of Fe-Al-Si is fused and connected. CONSTITUTION:A first core 1 having a coil winding window and a second core 3 having the metal magnetic film 2 of Fe-Al-Si are fused and connected with the faces having the metal magnetic film 2 opposed by glass 5 while forming a magnetic gap 4. At this time, the fusion glass 5 of 500 deg.C-620 deg.C in the fusion temperature of the glass 5 (temperature having viscosity of 10 poise) is used to substitute the atmosphere in a furnace by an inactive gas such as Ar or N2 and then, fuse in a prescribed temperature profile so as to maintain an oxygen density of 50-300ppm at that time.

Title: Coating apparatus and coating method
Inventor: SUZUKI TOMOHIRO
IPC: H01J11/42
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To achieve stable coating state at once in a narrow margin at the time of applying a paste to a substrate by a die coater. SOLUTION: At the coating starting part, the timing of paste discharge and the timing of starting relative movement of a die head 12 and a substrate 11 are controlled so as to eliminate a region where the coating film thickness is unstable and carry out patterning while stably keeping a prescribed coating film thickness uniform from the coating starting point.  At the coating starting point, a liquid sending pump 14 is connected to a circulation route 16 synchronously with stopping discharge of the liquid sending pump 14, so that the liquid pressure of the paste in a supply route 15 can be released to the circulation route 16 to lower the coating liquid pressure to be applied to the die head 12 on completion of the coating and consequently, dripping of the paste at the coating terminal point and leakage of the paste on completion of the coating can be prevented to carry out patterning of a coating terminal end evenly at a high precision.

Title: Magnetic recording medium and production thereof
Inventor: FUKAZAWA TOKUMI
IPC: G11B5/72
Filed: 1987-12-23
Abstract: PURPOSE:To improve the sliding resistance characteristic of a magnetic disk by using helium for a sputtering gas and forming a carbonaceous film on a magnetic film. CONSTITUTION:The helium is put into the sputtering gas at the time of forming the carbonaceous film 1. Namely, the temp. of the surface of a substrate 5 rises sharply upon staring of sputtering of the film formation is executed by a sputtering method is general. A large thermal strain is generated in the film and the adhesive power of the film to the subsurface decreases largely if the temp. changes sharply in a short period of time. The radiation of heat from the surface of the substrate 5 increases if the helium having small specific heat is used for the sputtering gas. The rise of the substrate 5 temp. is then lower than in the case of using gaseous argon. The carbonaceous film having the excellent sliding strength is thereby obtd.

Abstract: PURPOSE:To reduce a series resistance value and to improve temperature characteristic by providing a second conductivity type buffer layer, a first conductivity type current blocking layer and a second conductivity type contact layer on a second conductivity type second clad layer having a stripelike ridge of an inverted trapezoidal section. CONSTITUTION:A first conductivity type first clad layer 2 provided on a first conductivity type board 1, and an active layer 3 provided on the layer 2 are provided, a second clad layer 4a made of a P-type AlGaAs formed on the layer 3 has an inverted trapezoidal ridge. Electrons and holes implanted into the layer 3 are recombined to radiate a light. When the supplied current is increased, an induction radiation is started to a laser oscillation, and a current narrowing is conducted in a current path along the inverted trapezoidal ridge 10a. Accordingly, even if the effective width of the injecting current to the layer 3 is narrowed, the current path is broadened at the top of the ridge 10a as compared with the bottom. Thus, a series resistance value when the injecting current value is injected to the same layers 3 is reduced, and temperature characteristic as a device is improved.

Title: Solid-state image pickup device
Inventor: SEKINE KOICHI
IPC: H04N5/335
Filed: 1989-12-14
Abstract: PURPOSE:To facilitate the signal processing and to prevent color mixture by forming part of a CCD charge transfer vertical register with a transparent transfer electrode, applying photoelectric conversion, and using the vertical register as a 2nd picture element group storing generated charge. CONSTITUTION:A 3-phase drive CCD charge transfer vertical register 121 sets a transfer electrode phi3 among transfer electrodes phi1-phi3 receiving 3-phase clock pulses to a low level and sets the transmission electrodes phi1, phi2 to a high level. Thus, the vertical register 121 acts like a 2nd picture element group storing the charge generated through photoelectric conversion as well as like a 1st picture element group transferring the charge stored in picture element arrays 11a, 12a, transfers the charge generated in itself to the lowermost section and gives the charge to a horizontal register 21 thereby transferring the charge generated by the 1st picture element group. As a result, in the case of color reproduction, since the color signal is outputted in time series for each color signal, then even when the transfer efficiency of the horizontal register 21 is deteriorated, the possibility of mixed color is precluded and the signal processing is easily implemented.

IPC: G01C15/02
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To shorten the waiting time of the later step by providing a hole at a floor type frame weir plate on a ground marking point, raising the point from a lower storey to a transparent plate via the hole, connecting the point after concrete is placed, and drawing a ground marking reference line of an upper storey. SOLUTION: A hole 2 is perforated at a marking position. A long bolt 5 is mounted at the bedrock 4 of an omnia plate 1, and an acrylic plate 7 is mounted at the upper end of the bolt 5. A ground marking point is emitted from a lower storey to the lower surface of the plate 7 by using a laser vertical unit by utilizing the vacant time before floor concrete placed at the job site is placed on the plate 1, and the mark is formed on the upper surface. After the concrete is placed, the points on the plate 7 are connected to draw a ground marking reference line on the upper storey. Accordingly, since the marking can be conducted before the floor concrete is placed on the plate 1 of the upper storey, only the points may be connected and the reference line may be drawn after the concrete is placed.

Abstract: PURPOSE:To reproduce a wide aspect pattern even from any video signal by using a wide aspect video signal for a 1st video signal and using a video signal of the existing NTSC system for a 2nd video signal. CONSTITUTION:When the aspect ratio of a reproducing video signal is discriminated to be 5:3, an aspect ratio conversion circuit 19 converts the aspect ratio of the reproducing video signal from 5:3 into 4:3 and when the aspect ratio of a reproducing video signal is discriminated to be 4:3, an aspect ratio conversion circuit 19 converts the aspect ratio from 4:3 to 5:3.

Moreover, the switch circuit 21 selects a reproduced video signal when the aspect ratio of the reproduced video signal is discriminated to be 4:3 and selects a conversion output of an aspect ratio conversion circuit 19 when it is discriminated to be 5:3. Thus, the wide aspect pattern is reproduced even when the signal is either the wide aspect video signal or the NTSC video signal.
