Title: Recording apparatus
Inventor: TSUKAMOTO TAKAHIRO
IPC: B41J29/13
Filed: 1989-04-21
Abstract: PURPOSE:To prevent the generation of an undesirable recording result by prohibiting the input of a recording order by at least a keyboard in a cover open state. CONSTITUTION:When a low level signal is inputted to input ports KD0 - KD7, a control part 2 detects key input to perform the processing of various data or the recording operation due to a recording mechanism M. When the cover of the recording mechanism M is opened and a cover switch 5 becomes an OFF-state, the input/output of an NAND gate is prohibited. In this state, a signal wire 9 is held to a high level as it is even when any key of a key matrix is pushed and, even when a high level signal is successively issued to output ports KS0 - KS7, a signal line 4 does not become a low level state. Therefore, when the cover is opened, a key input state becomes a prohibition state and the operation of the recording start key contained in a keyboard 1 is also neglected. By this method, recording operation is prohibited and recording inferiority in a cover open state is prevented.

Title: Pulling of single crystal silicon, device for pulling up the same and graphite crucible or quartz crucible
Inventor: MAEDA SUSUMU
IPC: C30B29/06
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a device for pulling up a single crystal silicon, capable of prolonging the lives of a quartz crucible and a graphite crucible by inhibiting a reaction between both the crucibles. SOLUTION: This device 10 for pulling up single crystal silicon has a quartz crucible 14 and a graphite crucible 12 tightly brought into contact with the quartz crucible 14. Therein, a SiC coat 36 used as a reaction inhibitor is applied to the surface of the graphite crucible 12 tightly brought into contact with the quartz crucible 14. The application of the SiC coat 36 to the surface of the graphite crucible 12 can prevent the direct contact of both the crucibles. Since a reaction between both the crucibles under a high temperature environment on the pulling of the single crystal silicon 42 is inhibited, the thickness reduction of the graphite crucible 12 and the thickness reduction of the quartz crucible 14 can be decreased, respectively.  Thereby, the lives of both the crucibles can be prolonged, and the reduction of a cost for pulling up the single crystal silicon 42 and the enlargement of the diameter of the single crystal silicon can be achieved.

Abstract: PURPOSE:To detect precisely the height of an electrode from a packaging plane by detecting a line of intersection of the height of the electrode measured discretely with a virtual packaging plane. CONSTITUTION:Image pick-up devices 5a to 5d pick up images of electrodes of a semiconductor device 1 and a detecting means 9 of the height from a reference plane detects the height of each electrode. Next, the means 9 delivers information on the height of the electrode to a plane contact electrode detecting means 17, and based on this information, the means 17 outputs information on positions of three plane contact electrodes which seem to be in contact with a packaging plane. A packaging plane detecting means 19 outputs information on a virtual packaging plane passing through the three plane contact electrodes, on the basis of the informations on the positions of the plane contact electrodes, and a detecting means 21 of the height from the packaging plane detects the height of the electrode from the virtual packaging plane and checks whether the virtual packaging plane is the actual packaging plane. When it is the actual packaging plane, the means 21 takes the detected height of the electrode as the height of the electrode from the packaging plane, and when it is not, the means outputs a re-detection signal 22 to the means 17 so as to repeat the detection of the virtual packaging plane. Thereby the height of the electrode can be detected.
