Abstract: PURPOSE:To enhance the reliability of an Al wiring by a method wherein the sputtering requirements to form a high melting point metallic thin film are optimized and moreover an Al film is successively formed without exposing a wafer to the atmospheric air after the formation of the high point metallic thin film. CONSTITUTION:While a silicon semiconductor substrate 1 is being heated at the temperature not exceeding 150 deg.C enabling a high melting metal to be maintained in fine polycrystalline state, the high melting point metal thin film 5 comprising Ti is formed on the silicon semiconductor substrate 1 by sputtering process. Successively, an Al film to be an Al wiring 6 is formed on the high melting point metal thin film 5 to make both films 5 and 6 react to each other. The Al film is formed on the smooth surface of the high melting point metallic thin film 5 comprising fine polycrystalline element which is not yet oxidized so that the high melting point metal and Al may react uniformly to each other in the case of forming the Al film to equalize the grain diameter of Al. Resultantly, the resistance of the Al wiring to the electromigration and stressmigration can be enhanced.

Filed: 1982-09-06
Abstract: PURPOSE:To start automatic focus adjusting operation associatively with the depression of the shutter release button of a camera, and to stop the display of the focus state of the camera during this automatic focus adjusting operation. CONSTITUTION:When the power source switch SW2 of the camera is on and the power source switch SW23 of a photographic lens barrel is off, a power source battery E2 is not connected to a circuit and focusing operation is not performed. Normally, the output of a timer circuit 5 is at a level ''L'', transistors (TR) Q2, Q3, and Q4 are off and a constant voltage circuit 10 does not operates, so a focus state detecting and displaying circuit 15 is not powdered on and the focus state is not displayed. When the shutter release button is half-pressed and a focus detection command switch SW1 is closed, an ''H''-level signal is inputted to the timer circuit 5, whose output is inverted to a level ''H'' for a specific time to turn on TRs Q3 and Q4; and the constant voltage circuit 10 and focus state detecting and displaying circuit 15 start operating. Then, one of the 1st or the 3rd output terminal is held at the level ''L'' to turn on one of light emitting diodes LD1-LD3, so a distance adjusting member is operated manually to obtain an in-focus state.

Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To protect a stored CD, and in particular, to prevent a recording surface of the CD from being damaged while a package of envelope type is used. SOLUTION: A protective sheet 30 is stored in a flat, paper bag body 10 together with a CD 20 so that the protective sheet 30 is abutted on a recording surface of the CD 20.

IPC: E02D3/10
Filed: 1995-05-17
Abstract: PURPOSE: To use water for the service of potable water or agricultural water and collect or store liquid, such as oil and use a ground open space of facilities by storing artificially ground water or spring water and securing a stable amount of water for a water supply source. CONSTITUTION: Ground water or spring water is introduced from a liquid supply device 3 where mixed grits and floating articles are removed and then are permeated in a recharge pond 1 and stored in a storage layer 6. In this case, a tank 2 provides both a water storage function and a water shielding wall at the same time. The water stored in the recharge pond 1 and the tank 2 is taken out from a supply opening of the tank 2. The tank 2 serves as a member which houses water and damps up the storage layer 1 where it is constructed easily and at low cost as well Furthermore, water is stored underground and flows down spontaneously by gravitation, thereby reducing the unification of water temperature and a water staggering area.  This construction is employed even in the case when it is used as facilities which store oil, waste liquid, other liquids, thereby preventing environmental breakdown and enabling hygienic control to be carried out.

A control device 13 specifies an optimal diluent addition amount based on the detected temperature and humidity and gives a command to a control device 14. A diluent addition device 10 adds a diluent 17 for ink viscosity adjustment from a diluent liquid tank 9 to an ink circulation system by the amount specified by the control device 14. Thus the effect of environmental conditions (temperature and humidity) on a change in ink viscosity can be minimized.

Inventor: FUSHIMOTO HIDEO
IPC: G06F15/02
Filed: 1978-12-15
Abstract: PURPOSE: To simplify handling operations and prevent forgetting of operations and erroneous operations by providing a display and operation lock releasing switch in a battery room and operating the switch above by a cover when the cover is closed after battery loading.  
     CONSTITUTION: When cover 5 is pushed in the arrow direction while sliding it on shelf 6, the folded part of hook-shaped contact 10 is pushed by protrusion 11 of cover 5 and is brought into contact with linear contact 9, thus releasing lock. When protrusion 11 gate over hook-shaped contact 10, contact 10 is separated from contact 9 due to its own elastic secovery force and is returned to the original state. Cover 5 has elastic pawl 12 fitted to the receiving entrance of electronic calculator main body 1 with watch and is fixed to calculator main body 1. Meanwhile, in case that cover 5 is removed from computer main body 1, lock is not released because protrusion 11 pushes contact 10 in a direction where contact 10 is separated from contact 9. Consequently, even if cover 5 is removed erroneously, the lock releasing function is not operated, and operations are not cleared.

Abstract: PURPOSE: To reduce overshoot and permit stable operation to be obtained by changing the loop gain according to the rotational angle of the motor.  
     CONSTITUTION: When a pulse Pb is produced from a control circuit 21, a counter 13 is peset to a goal value specified by a preset circuit 14, and a decoder 15 supplies a signal to a switch circuit 23 according to the content of the counter 13 to let a control signal from a control circuit 21 to be supplied to a motor 10. When the rotational angle of the motor 10 approaches a goal value, the content of the counter 13 approaches zero, causing switching of the switch circuit 23 to the side of an amplifier 17 to provide a closed loop. Before the rotational angle of the motor 10 reaches the goal value, a transistor Q 1  is off, so that the gain of the amplifier 17 is low. After the reaching of the goal value, the transistor is on for an overshoot period, so that the gain of the amplifier 1 is increased.
