Title: Ion implantation device
Inventor: NOGAMI TSUKASA
IPC: H01J37/317
Filed: 1990-02-22
Abstract: PURPOSE:To relax the load torque imposed on the motor rotating an arm by providing a pneumatic counter balancer, and connecting the output shaft of this actuator to the rotation center of the arm. CONSTITUTION:In case of rotating an arm 22 by a motor 18, the actuator of a counter balancer 30 also interlocks. At this time, if compressed air is supplied beforehand from a pneumatic part to the actuator, the internal volume of the actuator decreases and the inside pressure rises when the arm 22 rotates downward, so the compressed air is discharged by that amount. Reversely, when the arm 22 rotates in the rise direction, the volume inside the actuator increases and the inside pressure decreases, so compressed air is supplied by that amount through a pressure reducing valve. The difference between the torque of this counter balancer 30 and the torque by the arm, etc., becomes the load torque falling on the motor 18, and the load torque imposed on the motor 1 8 can be decreased sharply.

Title: Uninterruptible power unit
Inventor: HATTORI MASAHIKO
IPC: H02J9/06
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To make turn on/off of the power supply to a peripheral device possible in an interlocking way with the turning on/off of the power supply to a terminal device connected to an uninterruptible power unit without human intervention nor connecting any special device and, at the same time, to prevent the capacity of the uninterruptible power unit from becoming excessively large. SOLUTION: An uninterruptible power unit is provided with a main plug socket 2 to which a terminal device is connected and a first sub-plug socket 3 to which a peripheral device that requires backup when a power failure occurs is connected, and a second sub-plug socket 4 to which a peripheral device that requires no backup is connected. A power supply control section 7 detects the power supply turn-on/off state of the terminal device 8 connected to the plug socket 2 and controls the power supply to the sub-plug sockets 3 and 4 in an interlocking way with the detected state.  Since a main control section 5 outputs a direct current from a battery to the plug socket 2 and sub-plug socket 3 after converting the current into an alternating current, but does not output the alternating current to the sub-plug socket 4, when the power failure occurs, the capacity of the uninterruptible power unit is prevented from becoming larger at the time of calculating the capacity.

Title: Test pattern of printed wiring board
Inventor: KIYOTA SHINICHI
IPC: H05K3/42
Filed: 1995-03-02
Abstract: PURPOSE: To surely check the reliability with a small-sized test pattern by providing a land, which connects the inwall conductor of a through hole with the pattern of printed wiring constituted on a printed wiring board, with a cut. CONSTITUTION: In the case of connecting many through holes in series and performing severe evaluation test, for the shape of each land, the contact area with the inwall conductor (usually, this is always 360 deg.) of the through hole is reduced by retrenching an ordinary whole periphery type land (circular) into fan shape. The connection between the land 1 and the inwall conductor 3 of the through hole does not get disconnected until the whole (all over the periphery) of the connection go to connection trouble. Accordingly, if this connection part is designed to be narrow, it becomes easy to be disconnected. Since the test pattern is made narrow at the connection part in the land 1, this is easy to be disconnected more than the ordinary through hole of a product, so it is easy to judge whether the product is superior or inferior in evaluation test or the like.

Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To suppress kink generation and deterioration of immunities of a gate oxide film caused by local thinning of a gate electrode directly under a gate electrode. SOLUTION: Regions or specific parts 29a and 29b1 as edges of a trench 31 in a silicon substrate 11 which are positioned directly under regions 23a and 23b scheduled for formation of a gate electrode, are subjected to a silicon- ion implanting process to convert the specific parts 29a and 29b1 to amorphous parts. The edges (specific parts) of the trench positioned directly under the gate-electrode formation scheduled regions are formed as the amorphous parts, so that, when a gate oxide film is formed by thermal oxidation after formation of an inter-element isolation region, parts of the silicon substrate corresponding to the trench edge parts can be effectively oxidized and thus the gate oxide film directly under the gate electrode can be made thick.
