Title: Method for conforming normal operation in remote maintenance system
Inventor: HAYASHIDA TAKESHI
IPC: G06F11/30
Filed: 1990-03-30
Abstract: PURPOSE:To confirm the routine normal operation of a device to be maintained by connecting the maintained device to a remote maintenance center at each fixed time and allowing the center to check whether the maintained device is connected at proposed time or not. CONSTITUTION:Plural devices 2a to 2n to be maintained are connected to the remote maintenance device 1 through lines at each proposed connection time and the device 1 decides the existence of their connection at the proposed connection time. Thereby, a maintenance man can know the normal operation of the devices 2a to 2n by their periodical connection. On the contrary, an abnormal state can be estimated from no periodical connection. Since the maintained device which is not connected at the proposed connection time is informed, hardware of software abnormality can quickly be detected by investigating the connection disabled cause of the disconnected device.

Filed: 1987-04-06
Abstract: PURPOSE:To uniformly etch a semiconductor wafer by a method wherein, after the semiconductor wafer has been dipped into a chemical liquid and has been etched, the semiconductor wafer is taken out from a side which has been dipped first. CONSTITUTION:When a semiconductor wafer 3 is to be etched after it has been immersed in a chemical liquid 2 filled in a liquid tank 4, the semiconductor wafer 3 is dipped into a chemical liquid 2 and is etched; after that, the semiconductor wafer 3 is taken out from a side which has been dipped first. For example, a tip-end edge a' of the semiconductor wafer 3 is held by using a jig such as a pair of tweezers or the like and is tilted downward, and one edge (a) a as the head is immersed in the chemical liquid 2. The semiconductor wafer 3 is dipped into the chemical liquid 2 until an etching duration expires; and after the duration has expired, the wafer is tilted upward by deciding the edge (a) as the head and is taken out from the chemical liquid 2. By this setup, the duration from the time when the semiconductor wafer is dipped into the chemical liquid up to the time when it is taken out becomes equal over the whole surface of the wafer; accordingly, the etching duration uniformized over the whole surface.

Abstract: PURPOSE: To completely paint out a specified area without leaving any unpainted part. CONSTITUTION: A dummy expansion processing part 6 when finding a painting- out start point in a figure of one page stored in a graphic data buffer 5 performs dummy expansion of the line containing the painting-out start point of the lowermost part in a line buffer 3 and a figure closed area uppermost point search processing part 7 searches for the uppermost point in a painted-out closed area specified with the painting-out start point. When the uppermost part is not found, the line right which is one stage of the figure of one page above is expanded in the line buffer 3 and the uppermost point of the painted- out closed area is similarly searched for.  The figure of one page is expanded in the line buffer 3, line by line, upward in order to search for the uppermost point of the painted-out closed area and once the uppermost point is found, the position of the painting-out start point is replaced with the uppermost point.

Title: Vacuum/pressure furnace
Inventor: NAKAMU EIJI
IPC: F27B5/14
Filed: 1995-04-11
Abstract: PURPOSE: To improve uniformity and homogeneity in heat treatment by providing a switching part on a heater's distribution circuit that is connected in a loop to switch connection states. CONSTITUTION: Rod heaters 5 are supported on electrodes 4 in a furnace body so that they extend in the axial direction of the furnace body. The furnace becomes equivalent to a circuit where the electrodes 4 are connected together into a loop with the rod heaters 5 having resistance (r) in between. To drive the circuit, a secondary side power source 7 of a three-phase transformer is connected to the electrodes 4 via a distribution circuit 6 with switches 8a and 8b. When the furnace is vacuum inside, power is supplied to the heaters 5 uniformly in the vertical and horizontal directions by operating the switches 8a and 8b to heat workpieces uniformly from the circumference.  On the other hand, when the furnace is kept in pressurized atmosphere by introducing gas, the switches 8a and 8b are turned over and the heaters 5 located at a higher positions receive power larger than that supplied to the heaters 5 located at lower positions. Thereby, the upper part is heated by the heaters 5 at relatively higher temperatures than the lower part and the vertical temperature difference caused by a convection current decreases.

Title: Piercing and cutting method of ceramics using laser light
Inventor: WATANABE YASUMOTO
IPC: B23K26/08
Filed: 1979-07-05
Abstract: PURPOSE:To stably perform piercing or cutting of arbitrary shapes with desired accuracy by controlling pulse separation at the time of irradiating electric gate type laser pulse light to the work. CONSTITUTION:The work A is set on a table 1 and air being supplied to a laser head 4 is blown to the work. The table 1 is moved based on the program data of a numerical control unit 7 and laser pulse light is radiated to the work A, whereby working is started. At this time, the signal proportional to the moving distance of the table 1 is sent by an encoder to a vector signal generator 8, so that the pulse signal proportional to the moving distance on the locus of a working mode is generated. This signal is sent to a counter circuit 9. Every time when the count number reaches preset number, the signal is sent to a laser generator 5, whereby the pulse separation of the laser pulse light is controlled. As a result, the laser pulse light synchronized to the moving speed of the work A is irradiated and the stable working is done.
