Title: Water leakage detector
Inventor: GOTOU TADASHI
IPC: G21C17/025
Filed: 1981-12-11
Abstract: PURPOSE:To detect the water leakage exactly, by compensating a hydrogen concentration signal by a temp. signal of cold trap refining which is delayed by the time in inverse proportion to the flow rate of a liquid metal. CONSTITUTION:A part from a main cyclic system 1 is transported to a cold trap 11 by a pump 10 and is subjected to a refining treatment and is returned to the system 11. Sodium is transported to a hydrogen detector 4 by a pump 2 and the pressure of hydrogen dispersed in a vacuum chamber 5 through a hydrogen dispersing film 3 is detected by a vacuum indicator 8. A temp. signal of cold trap refining detected by a thermometer is converted to a signal of back ground hydrogen concentration by an operator of hydrogen concentration 13. A signal of flow rate from a flow rate meter 12 is converted to a delay time signal in accordance with the delayed time by a delay time operator 14, and afterward it is inputted to an indicating meter 9 together with the signal of back ground hydrogen concentration and a signal from the vacuum indicator 8. The signal of back ground hydrogen concentration is delayed in accordance with the delay time signal in the indicating meter 9 and a signal from the vacuum indicator 8 is compensated by this way.

Title: Pressure contact type semiconductor device
Inventor: TAKIGAMI KATSUHIKO
IPC: H01L21/52
Filed: 1981-12-11
Abstract: PURPOSE:To prevent the breakdown of a semiconductor substrate in a pressure contact type semiconductor device by forming an electrically shielding region on the small part of the outer periphery of an electrode region, thereby removing a high stress region in the substrate. CONSTITUTION:An Si substrate 101 and a metal disc (having radius R) 100 are contacted within a circular region having radius r. In case of a GTO, they are contacted within a circular region which contains divided electrode regions. An electrically shielding region is provided, in case of R<=r, in the region 102 of the width W which is contacted with the peripheral edge 103 of the disc 100, and, in case of R>r, in the region 102 of an outer periphery 104. This is similar even in case of the metal plate 100 being polygonal. The shielding region may be formed by covering an insulating film such as polyimide, an SiO2 or the like. For example, an emitter electrode 112 and a polyimide layer 114 are formed on the mesa region of an Si substrate 111 on a W plate 110, a mesh gate electrode 115 is formed, and an insulating bank is formed around an insular emitter. When the metal plate is contacted under pressure with the bank. This GTO becomes irrespective of the electric characteristics in the high stress region of the substrate 111, thereby eliminating the irregular characteristics based on the irregular stress  distribution and avoiding the damage of the substrate.

Title: Capacity control mechanism for screw compressor
Inventor: MIYAMOTO TAKENORI
IPC: F04C18/16
Filed: 1985-09-09
Abstract: PURPOSE:To prevent burning of a drive motor under full-close of a capacity control valve by providing a mechanism for stopping the drive motor after operating for a predetermined time interval at the lock position exceeding over the full-close set position of the capacity control valve in the close drive control circuit of the drive motor for the capacity control valve. CONSTITUTION:Under closing operation of a capacity control valve 10, operation of a drive motor 20 for the capacity control valve 10 will continue until the capacity control valve 10 will pass over the full-close set position and reach to the lock position. The operation of the drive motor 20 is controlled through stop a mechanism such that it will be stopped upon elapse of a predetermined time interval after reaching of the capacity control valve 10 to the lock position. Consequently, even if there is a clearance such as a backlash in the drive transmission mechanism of the capacity control valve 10, the capacity control valve 10 can be closed reliably while burning of the drive motor 20 due to continuous operation at the lock position can be prevented.

Abstract: PURPOSE:To mutually separate a heating roller and a pressure roller which mutually make contact to form a fixing nip part, enhance the radiation of the heating roller, and prevent the thermal damage of a transfer material nipped and carried by the fixing nip part. CONSTITUTION:A heating roller 1 is rotated by a motor 6 and a driving belt 9, and heated by a heating member 12. A pressure roller 10 is supported through a solenoid 15 and an arm 12 in such a manner as to be movable between the contact position making contact with the heating roller 1 to form a fixing nip part N and a retreat position separated from the heating roller 1 to release the fixing nip part N. When an abnormality such as jam is generated, the feed to the heating member 2 is stopped to stop the heating of the heating roller 1, and the pressure roller 10 is also mechanically separated from the heating roller 1 by the solenoid 15 and a spring member 16. Since a transfer material nipped and carried by the fixing nip part N is separated from the heating roller 1, it is never thermally damaged.

Title: Digital image combination method
Inventor: JOHN RANDALL FREDLAND
IPC: G03G21/00
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a composite image which is produced with least time and labor and can offer a special visual effect by controlling automatically the sizes and/or shapes of selected images based on the relation set previously between both images. SOLUTION: When an image that is previously stored is selected, a user/ customer performs a proper inspection to decide a specific image element that should be placed in an area 102. For instance, the height Hc of an element 110 of the image showing a child is adjusted to be coincident with the height Hj that secures a specific relation with a player 104. In other words, the height Hc of the element 110 is automatically corrected to be coincident with the height Hj after the height Hc is once decided. Thus, the height Hj is selected so as to give an illusion that the element 110 of a selected image such as a child, etc., is larger than the image of the player 104.
