Title: Thin film growing method
Inventor: MIYAGI MASAHIDE
IPC: C23C16/24
Filed: 1984-07-25
Abstract: PURPOSE:To form a selective film having the pattern of uniform characteristics in a highly precise manner by a method wherein a metal mask is formed using a magnetic material, and a magnet is installed on a heat equalizing plate consisting of non-magnetic material to be superposed on the reverse side of a substrate. CONSTITUTION:A rare-earth magnet 3 is buried in the upper surface of an aluminum heat equalizing plate 2 which is stacked on the upper surface of a glass substrate. A metal mask 4 consisting of magnetic stainless steel is superposed on the lower surface of the substrate 1, and the metal mask 4 is supported by a stainless steel frame 5. The heat equalizing plate 2 is heated up to 300 deg.C by the radiant heat 6 coming from the heater arranged at the upper part, and the substrate 1 is heated by the heat equalizing plate 2. The silicon 7 decomposed from silane gas is deposited on the lower surface of the substrate 1 through the window part of the metal mask 4 consisting of a magnetic material. As the metal mask 4 is attracted to the magnet 3 and tightly fixed to the glass substrate 1 while the silicon 7 is being deposited and it does not come up, an a-Si film can be formed in a highly precise manner in acccordance with the pattern of the mask 4.

Title: Inspection device for bonding pad
Inventor: SCHAMBERGER FLORIAN
IPC: G01R31/316
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To enable a circuit mounted on a semiconductor chip to detect whether or not a bonding wire is connected to a part of a bonding pad from a signal taken out of the part, by dividing a bonding pad into two parts at least. SOLUTION: A bonding pad 1 is divided into two parts 3, 4 and the parts 3, 4 are separated by an interval 5. Electric resistance between the parts 3, 4 is almost infinite if they are not connected by a bonding wire. However, if the parts 3, 4 are connected by a bonding wire 2, resistance between the parts 3, 4 is approximately 0. For example, when the part 4 alone is electrically connected to the bonding wire 2, connection of the bonding pad 1 by the bonding wire 2 is 'defective'. The state is immediately detected by a circuit provided to a semiconductor chip and it is possible to determine whether or not a semiconductor chip itself is subjected to proper bonding.

Namely, the condition that all light beams which are emitted from a point X5 and pass in a circle where the instrument is present enters the pupil of the eye (normally, pupil diameter: 3-6mm) is only satisfied so as to view the instrument without any distortion. For the lens 1 for enlargement, a combination of the spherical lens and Fresnel lenses may be used and both their convex surfaces are set opposite each other.

Title: Variable compression ratio type internal-combustion engine
Inventor: NAKAHARA MITSUHARU
IPC: F02D9/02
Filed: 1982-09-06
Abstract: PURPOSE:To prevent generation of knocking due to delay of control to a low compression ratio in the early period of acceleration by decelerating the opening speed of a throttle valve as the operation speed to increase the load onto the accelerator increases, in an engine equipped with a compression ratio changing mechanism which is hydraulically driven. CONSTITUTION:A sub-piston 13 is inserted into a sub-cylinder 11 which communicates to a combustion chamber 5, and said sub-piston is driven hydraulically to vary compression ratio. In such an engine, an operation speed detector 35 is installed onto an accelerating pedal 34, and a signal sent from said detector is inputted into a control circuit 33, and then a throttle valve 9 is controlled through an actuator 32. As the stepping-in speed of the accelerator 34 increases, control is executed so that the opening speed of the throttle valve 9 is gradually reduced with respect to the stepping-in speed. Therefore, by reducing the opening speed of the throttle valve 9 in sharp acceleration, increae of the compression ratio due to delay of retreat of the sub-piston 13 hydraulically driven and generation of knocking due to said increase can be prevented.

Abstract: PURPOSE:To provide a method for deciding more suitable operation schedule on a working line in which the change of an operating condition is considered and matching with actual circumstances when the operating condition of each operating equipment of the working line can be changed in connection with each other. CONSTITUTION:The frequencies of passes in each mill of a rolled stock which is rolled back and forth by a rough mill 6 and a finishing mill 26 which can be conveyed in both directions on a rolling line 2 can be changed in relation to each other. For example, when the frequencies of passes of the rough mill 6 is increased, the frequencies of passes of the finishing mill 26 can be reduced.
