IPC: H01L21/768
Filed: 1989-11-10
Abstract: PURPOSE:To obtain a titanium nitride layer which is superior in barrier properties by forming the titanium nitride layer at a titanium layer and further, forming another titanium nitride layer after laminating its layer on the surface of the initial titanium nitride layer. CONSTITUTION:A titanium layer 3 which is formed inside and at the surface of a contact hole 2a in an insulating film 2 formed on the surface of a diffusion layer 1a in a semiconductor substrate 1 is treated with heat and a titanium silicide layer 3a is formed at a part which comes contact with the diffusion layer 1a. Consequently, the formation of its diffusion layer makes possible the realization of ohmic contact which has a low contact resistance and is free from junction breaking between the titanium layer 3 and the diffusion layer 1a. Further, a titanium nitride layer 4 having a thicker film thickness is formed by a reactive sputtering process on the surface of a titanium nitride layer 3b that is formed on the upper face of the titanium layer 3. The titanium nitride layer 4 which is superior in barrier properties is thus formed and its layer obtains a favorable electric contact with an aluminum layer 5 that is formed on the surface of the above layer 4.

Title: Film thickness measuring method for airtight high frequency window and its airtight high frequency window
IPC: G01B15/02
Filed: 1991-10-16
Abstract: PURPOSE:To execute the measurement related to a variation of film thickness and a film quality after the film is formed by exciting the inside of an airtight high frequency window by a ghost mode frequency, measuring a Q value in its resonance state, and converting the film thickness from its measured value. CONSTITUTION:Since a thin film 4 exists in a place in which an electromagnetic field made by resonance is strong, a large loss is generated, therefore, energy stored by the resonance decreases, and a Q value decreases. Especially, when the resonance being a ghost mode of a frequency being below a cut-off frequency of a square waveguide 1 is utilized, the Q value becomes high because microwave is not transmitted to the waveguide 1, and a measurement of a loss quantity caused by the thin film 4 can be executed with high accuracy. That is, by using two probes 6a, 6b for excitation and detection, the resonance in the ghost mode frequency is measured, and from its measured value, the Q value is derived. Also, its Q value decreases due to a fact that a loss is increased by the thin film 4, therefore, that which appears in its decrease can be converted to film thickness. Accordingly, even after an airtight high frequency window is assembled, the measurement can be executed.

Because of this springiness, width directional stress is absorbed when inserting the electric connecting terminal 7 into the printed circuit board to prevent damage to these as well as to restrain the occurrence of solder cracks when thermal stress by a thermal shock acts on the soldering part.

Abstract: PROBLEM TO BE SOLVED: To improve the appearance of a laid roof, and to enhance a water flow on the top face of the roof by molding the eave-side end face of a tile body in a shape that the eave-side end face is retreated to the ridge side towards the eave-side edge of an underside from the eave-side edge of the top face. SOLUTION: An eave-side end face 7 is formed between the eave-side edge 5A of a top face 5 and the eave-side edge 6A of an underside 6 in a tile body 1, and the eave-side end face 7 is constituted so as to be inclined to the underside 6 side. When the tile body 1 is used for a roof on the south side, the eave- side end face 7 is viewed as a shade in the daytime when at least a solar altitude is high, the thickness feeling of the tile body 1 can be emphasized, and the quality feeling of the roof can be improved.  When the place of a contact between the eave-side end face 7 of a ridge-side tile body 1M and the top face 5 of an eave-side tile body 1N is covered with rainwater, rainwater is difficult to flow along the eave-side end face 7 because an angle between the eave-side end face 7 and the top face 5 is formed at a more acute angle, and rainwater is difficult to collect at the place of the contact between the eave-side end face 7 and the top face 5 and water ascending can be inhibited.

Abstract: PURPOSE:To prevent overcharge by providing a capacitor or an electric quantity element for storing the time to be elapsed before reaching a gas producing voltage after the start of charging and performing overcharge for an interval equal to one third of thus stored time. CONSTITUTION:A time memory capacitor Co (an electric quantity element may be employed in some case) is charged through a resistor R1 after start of charging until a gas producing voltage is reached, and the capacitor Co is discharged through a resistor R2 during extended charging operation. Time constant of the resistor R1 80d the capacitor Co and the time constant of the resistor R2 and the capacitor Co are set in the ratio of 3:1 in order to control the time T to be elapsed before a gas producing voltage is reached after start of charging operation and an extended charging time T/3, thus performing overcharge for an interval equal to one third of the time stored in the capacitor Co. According to the constitution, charging operation finishes instantaneously and excessive overcharge can be avoided.

Title: Metal halide lamp
Inventor: MATSUNO HIROMITSU
IPC: H01J61/073
Filed: 1990-11-02
Abstract: PURPOSE:To obtain a lamp having no fluctuating arc, no flickering radiation light and a long life by using electrodes each having a recess at the tip in the metal halide lamp with the inter-electrode distance 10mm or below. CONSTITUTION:Electrodes 1, 2 each having a recess at the tip are used. When the electrodes 1, 2 each having the recess at the tip are used, electrons are emitted from the whole recess by the so--called hollow cathode effect, thus the occurrence of an arc spot is prevented. The fluctuation of an arc due to the movement of the arc spot is large near the tip of the electrode and small at the center section of the arc, thus the effect of the flickering suppression of the radiation light is remarkable in a metal halide lamp with the inter- electrode distance 10mm or below. The lamp having no fluctuating arc, no flickering radiation light and a long life is obtained.
