Title: Production of thin-film magnetic head
Inventor: WADA KUMIKO
IPC: G11B5/31
Filed: 1989-11-02
Abstract: PURPOSE:To improve reproduction efficiency and to obtain the thin-film magnetic head which meets the trend toward narrower tracks by again simultaneously and integrally forming a lower magnetic layer facing an upper magnetic layer via a magnetic gap part at the time of forming the upper magnetic layer to a prescribed shape. CONSTITUTION:The lower magnetic layer 2 is formed on a substrate 1 at the prescribed size set wider than the upper magnetic layer 3 and the post stages are progressively progressed. The lower magnetic layer 2 is etched down to >=1mum depth from the end of the magnetic gap 11 formed by the lower magnetic layer 2 and the depth which does not exceed the uppermost end of a coil plane, simultaneously with the formation of the upper magnetic layer 3 in the stage for forming the upper magnetic layer 3 consisting mainly of a photolithography technique and ion milling method. The misregistration in the relative positions of the upper and lower magnetic layers 2, 3, the leakage of magnetic fluxes occurring in the dimensional differences of the respective widths, the increase of crosstalks by the bleeding of recording, and the degradation in recording efficiency occurring in the generation of partial magnetic saturation by the concentration of the magnetic fields to the edge part of the upper magnetic layer are prevented in this way and the thin-film magnetic head which has the good characteristics and meets the trend toward the narrower tracks is obtd.

Title: Reliability test method for image display element
Inventor: SAKAI YASUHIKO
IPC: H01J9/42
Filed: 1992-10-26
Abstract: PURPOSE:To confirm reliability in a short time, and shorten a development period by increasing a potential difference between the inner and outer walls of a display unit via a temperature rise and humidification, and activating the motion of an alkaline component in the glass of the display unit. CONSTITUTION:An image display element is placed in a constant temperature bath kept, for example, at 80 deg.CX80 deg.C and a vessel 1 is supplied, for example, with high voltage of ten-odd kV from an anode terminal 2. Uniform high voltage is thereby applied to a phosphor 3 coated on an image screen. Also, a plane electrode 4 is supplied with the predetermined potential from a lead terminal 7 for focusing electrons emitted from a ray cathode 8. Also, a signal is applied for causing the deflection and landing of the electrons on the prescribed position of an element body 3. In this case, a potential difference between the inner and outer walls of a vessel 1 increases, due to the grounding effect of the outer surface thereof through the active motion of molecules at high temperature and humidity. Consequently, the motion of an alkaline component becomes active. Thus, various problems or the like related to the deposition, diffusion and soluble state of the component, and also the reliability of measures against such problems can be confirmed in a short time, and a development period can be shortened.

Title: Program exposure controller
Inventor: KATO TAKEHIRO
IPC: G03B7/097
Filed: 1987-11-13
Abstract: PURPOSE:To prevent a camera shake and to make the best use of the descriptive characteristic of a photographing lens by narrowing down an aperture when a focal distance is short, opening the aperture when the focal distance is long and determining a limit exposure time so that the longer the focal distance is, the higher speed is set for the limit exposure time. CONSTITUTION:A focal distance output means 1 outputs the information of the focal distance (f) of the photographing lens. Based on said information, a limit exposure time output means 3 outputs the information of the limit exposure time TVH that the longer the focal distance (f) is, the higher speed is set for the limit exposure time and a program constant output means 4 outputs a program constant alpha that the shorter the focal distance (f) is, the steeper the tilt of a program line becomes. When the exposure value EV is smaller than a reference exposure value (TVH+AVO), a program arithmetic processing means 6 outputs the information of the exposure time TV which becomes proper with an opening aperture value AVO and an opening aperture. When it is the reference exposure value or above, the means 6 outputs the information of the proper aperture value AV and the exposure time TV by using the tilt part of the program line. Thus, the camera shake can be prevented and the descriptive characteristic of the photographing lens can be made the best.

Title: Drum heater
Inventor: ENDO HIDEKI
IPC: G03G15/00
Filed: 1988-11-15
Abstract: PURPOSE:To supply electric power to the heater without using a sliding member by allowing a secondary current to flow into a secondary coil in a photosensitive drum through a supporting axis with the aid of a magnetic field arising when a primary current flows into a primary coil. CONSTITUTION:The secondary coil 6 is wound onto a 2nd bobbin 5, in which the supporting axis 1 is inserted and is connected to the heater 4 through a terminal 20. The 2nd bobbin 5 surrounds the supporting axis and is placed on the side of a drum flange 18a facing the interior of the photosensitive drum 2. A 1st bobbin 7 is fixed to a lateral plate 10a with a screw 12 and the primary coil 8 is wound onto the 1st bobbin 7. When the primary current flows into the primary coil 8, a magnetic field is created to generate inductive electro motive force in the secondary coil 6 through the supporting axis 1 composed of a magnetic body. Consequently, the secondary current flows to energize the heater 4. Thus, the surface temperature of the photosensitive drum 2 can be maintained stably without developing malfunction in a control circuit, etc.

Title: Heating method of vacuum, pressure and press formed synthetic resin sheet
Inventor: SHIMA YOSHIHARU
IPC: B29C51/42
Filed: 1989-11-06
Abstract: PURPOSE:To prevent softened sheet from sagging and unlimited volumetric expansion of thick-walled and large-sized article from occurring even through heating for long period of time by a method wherein an airtight box is screened by synthetic resin sheet into an upper and a lower chambers so as to heat the synthetic sheet from just above or below under the condition that compressed gases having the same pressure as each other are introduced in the upper and the lower chambers. CONSTITUTION:Compressed airs having the same pressure as each other are introduced from pressurized air source 4 under the condition that control valves 5 and 6 are opened in an upper chamber 11 and a lower chamber 12, both of which are formed by partitioning an airtight box 1 with synthetic resin sheet 10 at the middle position of the box. At the same time, heaters 3 and 3' are moved out of heater housing case 25 to the neighborhood above or below the synthetic sheet 10 so as to heat and soften the sheet. Thus, since the same positive pressure is applied from above and below the synthetic resin sheet 10, the sheet 10 is pinched by the airs having the same pressure, resulting in developing neither sagging by its own weight nor unlimited volumetric expansion even at elevated temperature. Accordingly, the controlling of the wall thickness or the like of the sheet becomes possible by adding simple constitution such as a balance cylinder or the like.

Inventor: YUU KOREN
IPC: H01S5/50
Filed: 1993-10-26
Abstract: PURPOSE: To monitor an optical gain by a method, wherein a semiconductor laser amplifier is separated into three zones, insulated electrically. CONSTITUTION: A contact of an uppermost part of a semiconductor laser amplifier 10 is separated into three zones. These three zones is separated into a center zone 12, input zones 14 of a frontal small face and a rear small face separated by gap regions 18, 20, and an output zone 16. These three zones 12, 14, 16 are electrically insulated to each other, by implanting ions into the gap regions 18, 20. If a forward bias is applied parallel to these three zones, an optical gain of the semiconductor amplifier relates to the ratio of a voltage in two zones at the both ends. Further, this relation depends only on a fixed amount such as the length of the three zones.
