Abstract: PURPOSE: To form multilayer winding in which the ground metal is not remained, by using the metallic film able to be etched through the hole for the ground of metal conversionable into insulation metallic oxide with the anodic oxidation such as Al.  
     CONSTITUTION: On the substrate 1 on which semiconductor elements are formed, the insulation film 2 having the opening 16 is placed and the Ti.W film 11 being ground metal and the upper wiring Al film 3 are coated with lamination. Next, the mask 4 is formed on the part remained as wiring, and the unnecessary film 3 other than the wiring 3 is converted into perforated Al 2 O 3  film 5 with anodic oxidation of the film 3. After that, only the film 11 located under the film 5 only is removed by using CF 4  gas and performing plasma etching through the holes of the film 5 and the hollow part 12 is caused between the films 5 and 2. Thus, around the wiring 3, the multilayer wiring construction not presenting the residual of Ti.W film 11 can be obtained

Abstract: PURPOSE:To make a production process easy and to reduce an irregularity in a characteristic by providing a substrate having a wiring pattern on its surface and composed of a ceramic of a prescribed thermal conductivity, and a chip component mounted on the substrate. CONSTITUTION:A substrate 5 is made of a ceramic material whose thermal conductivity is 0.02cal/cm/sec.c or lower.

When the pad-system transcription printing method is used, the wiring pattern 4 can be formed on a three-dimensional object in one process; as a result, a manufacturing process is made easy. The substrate 5 is placed on a base 9; an FET chip 6 is placed on a part (alpha) and a resistance chip 7 is placed on a part (beta) of the substrate 5. They are soldered by a solder paste/reflow operation.

A thickness D3 of the image-side lens L2 is smallest on the optical axis and is increased according as going away from the optical axis. Formulas I and II are satisfied when the focal length of the whole of the system and the radius of curvature of the lens L2 are denoted as (f) and r3 respectively. Thus, a focusing lens whose various aberrations are compensated well is constituted.

Title: Contact type image sensor
Inventor: NAKAMURA KENICHI
IPC: H01L27/14
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent the destruction and damages to an LED element by static electricity, to improve reliability and to facilitate assembly by providing an element for protection for protecting a light emitting element from the static electricity. SOLUTION: A capacitor C1 is connected as the element for the protection of the LED element D1 parallelly to the LED element D1 of a light source device. A capacity equivalent to an electrified operator is denoted by Ca in the figure, an equivalent switch is denoted by S and it is indicated that the operator touches the terminal of the light source device or discharge is started. When the switch S is closed, the charges of the capacitor Ca are redistributed between the capacitor C1 for the protection and the maximum value of a voltage applied to the LED element D1 is reduced to the Ca/ (C1+Ca) multiple of the initial-value of the electrification potential of the capacitor Ca. An actual voltage is lowered further more than the maximum value by the influence of the time constant of the capacitor C1 for the protection and a resistor R.  Thus, a current flowing to the LED element D1 is reduced as well.

Title: Power supply circuit
Inventor: YAMASHITA HARUKI
IPC: G05F1/56
Filed: 1984-06-19
Abstract: PURPOSE:To reduce the power consumption of a backup power supply by connecting a transistor in series to a voltage detecting resistance and a control electrode of the transistor to an input power supply terminal respectively. CONSTITUTION:When the voltage impressed to an input terminal 1 is lowered, the gate voltage of an n channel MOSFET9 is also lowered and then cut off. Then an output terminal 2 has a high impedance. Thus a battery used as a power supply has no reduction of its lifetime in case a packup power supply is connected to an output terminal 2. Thus it is possible to secure the desired holding time even with a battery of a small capacity.

Title: Formation of long photosensitive film
Inventor: SENO MITSURU
IPC: B05D3/02
Filed: 1991-05-29
Abstract: PURPOSE:To provide a technique to form a long photosensitive film by which productivity can be increased without enlarging a device and also without deteriorating quality. CONSTITUTION:A photosensitive liquid is applied to a long iron plate B and the iron plate B is transported in the direction of an iron plate discharging aperture 14 from an iron plate introduction aperture 13 using a transport device. Next, the iron plate B is irradiated with a far infrared beam using a far infrared heater 22 to allow evaporation of water in the photosensitive liquid on the iron plate B and subsequently hot air is blown through a hot air nozzle 21. A turbulent current is generated by blowing the hot air to the iron plate B, then water vapor generated is mixed into the hot air efficiently so that the humidity of the hot air is reduced uniformly and subsequently the vapor is prevented from reaching a saturated vapor pressure level. The air is discharged from a discharge aperture 23 through a discharge duct 24 after allowing it to pass through the edge of the iron plate B. The iron plate B is efficiently dried by positioning the hot air nozzle 21 and the far infrared heater 22 alternately in an iron plate B transport direction.

Title: Complementary mos integrated circuit
Inventor: MOROZUMI SHINJI
IPC: H01L27/08
Filed: 1979-10-01
Abstract: PURPOSE:To improve the integrity of a CMOS-IC by forming a V-shaped groove on the junction surface between a substrate and a well and applying said technique to the isolation between elements. CONSTITUTION:A substrate is cut with a V shape in the vicinity of the junction surface between an N<-> type substrate 1 and a P<-> type well 10 becoming a P channel substrate, thereby removing the portion where a depletion layer may become broadended easily due to low density caused by the lateral expansion of diffusion, and the depletion layer is erased horizontally with each other. Accordingly, contact of the depletion hardly occur with a result that the minimum interval W becomes reduced between the P<+> type layer 11 and N channel side N<+> type layer 14 of P channel side. When the static memory cell of CMOS is applied with this, the distance between the P<-> and N<-> can be reduced from 16 to 6mum, and the isolating distance between the transistors can be reduced from 5 to 3mum.

Filed: 1982-07-19
Abstract: PURPOSE:To permit a top jaw to be replaced rapidly only by pushing an operating pin which is arranged to penetrate through the master jaw of a mechanical chuck into the cut-in part on the slant surface of a sleeve. CONSTITUTION:The engagement state between a top jaw 5 and an engagement member 11 is released by pushing an operating pin 16 which penterates through a master jaw 3 in the radial direction, into a cut-in part 18 formed on the slant surface of a driving sleeve 8, and the top jaw 5 is replaced. The engagement state between the top jaw 5 and the engagement member 11 can be maintained through the slidable contact between the operating pin 16 and the sleeve 8. Thus, the pushing-in stroke for the operating pin 16 can be reduced to the minimum value which is necessary for the engagement and release between the engagement member 11 and the top jaw 5, and thus rapid replacement of top jaw is permitted.
