IPC: G03G15/20
Filed: 1988-07-25
Abstract: PURPOSE:To prolong the service life of a roller by switching the connections of a core temperature detecting means and a cover temperature detecting means respectively with a roller temperature controller, controlling temperature based on the surface temperature of a elastic body during a copying stand-by time, and controlling the temperature based on the surface temperature of a metal core during a copying time. CONSTITUTION:The core temperature detecting means 5 and the cover temperature detecting means 6 are connected switchably with the temperature controller. During rising, the temperature is controlled based on the surface temperature of a core 3 so that the temperature of the core 3 is controlled to be below a bonding limit temperature. When the surface temperature of the cover 4 reaches a temperature prescribed in consideration of a fixing lower limit temperature, temperature control is switched so as to be performed by the surface temperature of the cover 4. When copying is started, the temperature is controlled based on the surface temperature of the cover 4. Thus, all during rising, standing by and copying, the core 3 is maintained to be below the bonding limit temperature, while the cover 4 is maintained to be above the fixing lower limit temperature. The service life of the roller can be thereby prolonged.

Title: Manufacture of semiconductor device
Inventor: YAMADA SHINICHI
IPC: H01L21/8249
Filed: 1989-07-17
Abstract: PURPOSE:To prevent a fluid insulating material from flowing into a hole by forming a contact hole for forming an emitter electrode after the surface of a semiconductor device is flattened as well as to secure a sufficiently thick insulation film between an epitaxial layer and an upper electrode by forming a thick insulation film before flattening. CONSTITUTION:Although a contact hole 13 has been usually formed at the same time as patterning of a gate electrode 6a and a base electrode 6b, the hole 13 is formed independently from patterning process of the electrodes 6a, 6b in this method. That is, a fluid insulating material is applied after formation of both electrodes and then the hole 13 is formed. Thus the hole 13 is not filled with the fluid insulating material so that etching is not necessary after formation of an emitter electrode 6c to form an upper electrode 11. Although etching is necessary as for other electrodes, formation of the electrode 11 is easy because other electrodes are not so deeply recessed as the electrode 6c. In addition since a thick insulation film 4b is formed before application, it can be sufficiently thick.

Title: Catheter
Inventor: PIITAA HENRII HANNAMU
IPC: A61M29/02
Filed: 1990-07-13
Abstract: PURPOSE: To obtain a well performed balloon expansion catheter of simple structure without fluid loss by fixing both ends of outer and inner shafts to each other so that the outer shaft comes shorter when a balloon is expanded ad making the excessive length caused by shortened outer shaft meet by bending the inner shaft in the balloon. CONSTITUTION: This catheter has an inner shaft 10 and an outer shaft 20 in which the outer shaft is put fixed relatively with the inner shaft at both of a patient side 2 and a grip side 3. The inner shaft having a hollow inside is made of soft plastic such as nylon. The inner diameter of the outer shaft 20 is made slightly larger than the outer diameter of the inner shall 10 so as to put a circular fluid passage between two shafts along the catheter. Expanding operation of the balloon 1 would cause the outer sleeve 20 to come shorter, which causes consequently the length of the catheter to come shorter. The change of the catheter length is adjusted through bending the inner shaft 10 in the balloon. This device remarkably simplifies the structure of an inflation housing 4 around the grip side 3 of the catheter due to an absense of any movable element.

Title: Transparent conductor and manufacture thereof
Inventor: KITAMURA MAKOTO
IPC: C01G9/02
Filed: 1994-08-05
Abstract: PURPOSE:To lower the alteration of resistance with the lapse of time by making a transparent conductor up of zinc oxide doped with an element of group VB or VIB elements in a periodic table and limiting the atomic ratio of the element to the total atomic number of the zinc atom and the element to be 0.1-10 atomic %. CONSTITUTION:There are V, Ta, and Nb among the group VB elements and there are Cr, No, and W are among the group VIB elements. The content of the element of the group VB or VIB elements in a zinc oxide film is preferably 0.5-5 atomic % of the total atomic number of zinc atom and the element and in the case of a group VB element, 0.5-5 atomic % is preferable and in the case of a group VIB element, 2-8 atomic % is preferable. The reason why the content is defined is because in the case the content of a group VB or VIB element is suppressed to low, resistance lessening effect by the doping can not sufficiently affects and thus high conductivity can not be provided and the resistance value changes greatly in high temperature and humidity as the lapse of time. Meanwhile in the case of high content, crystallinity is deteriorated and electric resistance increases sharply.

Filed: 1989-07-17
Abstract: PURPOSE:To upgrade straightness of a cut surface by outputting a control signal for lowering the cutting speed to a cut transfer means in compliance with the sensed displacement of a blade and providing a control means for outputting a control signal for increasing the decreasing the number of rotations on a rotation driving section of a cutting tool. CONSTITUTION:When a blade 10 is deflected because of cutting resistance or the like generated between a work 15 and an inner peripheral blade 11 and the cutting position is displaced in its axial direction, the displacement amount is sensed by a sensing means 22. At that time, a control signal lowering the transfer speed of the work 15 is output from a control means 23 into a driving motor 13 of a cut transfer means 14. As a result, the cutting speed of the work 15 is lowered and cutting resistance is reduced to control further larger deflection of the blade 10. Also, a control signal varying the number of rotations is output from a control means 23 into a driving motor 8 for rotary driving a main shaft 6, and the number of rotations of cutting tool 5 is varied correspondingly. As a result, the scale and direction of a displacement in the rotating direction are controlled to modify the deflection of the blade 10.
