Abstract: PURPOSE:To relieve thermal stress as well as the surface absorption of reactive gases such as an etchant gas and the like when an insulator film is formed and a subsequent heat treatment process is performed by forming the oxide film of a metallic wiring film between its metallic wiring film and the insulator film which covers the above metallic wiring film. CONSTITUTION:After forming a layer insulation film 8 on a P-type silicon substrate 1, an aluminum metallic film 10 is formed and an alumina(Al2O3) film 6 is formed on the surface of the foregoing aluminum metallic film to form a photoresist film 11. Then anisotropic etching is performed and patterning of the alumina film 6 as well as an aluminum electrode wiring layer 7 are performed. After the alumina film 6 is treated to prevent the formation of overhangs, the resist film 11 is removed to form a cover insulating film 9. Consequently, an interval between the upper face of the metallic wiring film 7 and the lower face of an insulator film 9 is covered by the metallic oxide film 6. Stress applied to a wiring film 10 is thus relieved when the insulator film 9 consisting of a cover film and the like is formed and subsequent heat treatment is performed. Further, its sedimentation of an etchant gas to the surface of the metallic film 10 is prevented at the stage of a heat treatment process.

Filed: 1994-09-28
Abstract: PURPOSE: To substantially prevent the peeling of a protective film in the resin part of a magnetic head which is exposed with a core and the resin for fixing the core on its sliding surface and of which the core and resin are coated with the protective film of CrN, etc. CONSTITUTION: The part of the resin 4 fixing the care 3 is coated with the protective film in the case the sliding surface A1 of the magnetic head H is formed with the protective film, such as CrN film, in order to improve the sliding characteristic with a magnetic tape T. The hardness of the resin is set at Barcol hardness of >=50 to <=70 in order to substantially prevent the peeling of the protective film in this resin part. The adhesion property of the resin with the protective film degrades and the protective film is liable to peel if the hardness is lower than this hardness. The protective film is liable to be peeled by the sliding force of the magnetic tape if the hardness of the resin is higher than the range described above. The life of the protective film is assured by setting the hardness of the resin within the range described above.

Title: Lighting system
Inventor: ISHII HITOSHI
IPC: H05B37/02
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To speedily put off light when the illuminance of circumference at daybreak or to speedily put on light when the illuminance is lowered by controlling an output of illumination load according to the change ratio of an illuminance value par unit time. SOLUTION: First and second determination values S1, S2 can be preliminarily set or can be set from the outside at the time of use. During operation of this system, a microcomputer measures an illuminance value L to compute a gradient ΔL/Δt. At the time Ta when the computation result is over a determination value S1 an illumination load 4 is put on while at the time Tb when it is over a determination value S2 the system is put off. Accordingly, through the determination with the inclination ΔL/Δt, artificial light and sun light can be detected separately. Consequently, there is less scattering in a lighting starting time and lighting terminating time caused by difference between installation positions and installation directions.

Title: Method for controlling temperature of metallic strip
Inventor: ADACHI KAZUNARI
IPC: C21D9/56
Filed: 1986-10-30
Abstract: PURPOSE:To decrease the time required for changing a furnace temp., the deviation of a target strip temp. and the length of a defective strip temp. in the titled method for controlling the fuel flow rate of a continuous annealing furnace by setting the fuel flow rates respectively at a max. and min. at the time of increasing and decreasing the furnace temp. CONSTITUTION:A combustion rate is set at an upper limit value QU simultaneously with changing the setting of the furnace temp. at the time theta0 in the case of; for example, increasing the furnace temp. The time theta1<a> is then set by calculating the calculation equation for predicting the relation based on the actually strip temp. measured with a thermometer for the strip temp. on the outlet side of a heating zone. The combustion rate is changed from QU to the combustion rate to be determined from the ordinary strip temp. control upon lapse of said time. The strip temp. is thereby controlled to the target temp. OTS at the time theta2<a>. The time required for changing the furnace temp. is thereby shortened at the time of changing the furnace temp. to the necessary furnace temp. when operating conditions are changed. In addition, the deviation of the strip temp. from the target value and the length of the defective strip temp. are decreased.

Abstract: PURPOSE:To realize an exact film thickness measurement which has eliminated an influence caused by an output variation, etc., of a light source, by bringing reference light and measuring light to a scan and a photometry with a shift of a minute time, and measuring the film thickness, based on its difference. CONSTITUTION:First of all, the reference light from a light source 2 for reference, and subsequently, the measuring light from a light source 1 for measurement, which has been delayed by a minute time are reflected by a rotary polygonal mirror of an optical scanner 3 and scan on the surface of a film to be measured 10, respectively. In this case, the reference light and the measuring light are detected successively by a pyrodetector 5 for power monitor, and its difference is derived. Subsequently, the reference light and the measuring light which have passed through the film 10 are detected successively with a shift of a minute time, respectively, by each detecting device 6a-6c..., and a difference of the photometric values is derived in the same way. Next, based on each data of a difference of measured values of two light beams of the reference light and the measuring light, thickness by each data can be measured by using an analytical curve which has been derived from an output value after transmission of a film of the same material whose thickness has been measured in advance, and its thickness.

Title: Vehicle operation monitor device
Inventor: HIROSE HIROSHI
IPC: F02D17/00
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To ensure economical operation by constantly monitoring operating conditions without spending extra time or manpower. SOLUTION: An operation monitor circuit 12 automatically forces an engine into a shutdown state as soon as a parking brake is operated into a parking position or after a predetermined period of time has elapsed while a vehicle remains stationary. This helps prevent fuel from being wasted while the vehicle remains stationary. In addition, this device determines the current operating mode and causes an alarm buzzer to sound when an engine speed or vehicle speed reaches a predetermined value corresponding to a normal-speed mode while the vehicle is running on an ordinary road (normal mode), and when the engine speed or vehicle speed reaches a predetermined value corresponding to a high-speed mode while the vehicle is running on an expressway (high-speed mode).  This allows engine speed and vehicle speed optimum for each current operating mode to be retained, which ensures both economical and safe driving.

Title: Skew detecting device
Inventor: IKEDA YASUHIKO
IPC: B41J13/00
Filed: 1993-10-18
Abstract: PURPOSE:To precisely measure a skew by providing two sensors for detecting the presence of a passing sheet, on one and the same axis perpendicular to a sheet conveying direction so as to detect a skew of the sheet if a difference occurs between the times at which the sheet passes by the sensors. CONSTITUTION:A printing signal is delivered to a printer, paper feed rollers 15 are rotated so as to feed the uppermost one of stacked recording sheets on a paper feed tray 10, to a printing position. The recording sheet led to a paper feed roller 15 is detected by register sensors 12 (12a, 12b) just before the printing position, the start of the printing operation is controlled by this timing. The register sensors 12, 12b are set respectively at positions at opposites ends of a recording sheet to be used, having a minimum size. If a recording sheet conveyed by the paper feed rollers 15 skews, a difference occurs between the times at which the sheet passes by the register sensors 12a, 12b, and accordingly, a skewing condition of the recording sheet is determined from this time difference. Thus, the sheet is discharged without printing.
