Title: Fitting shaft coupling
Inventor: HATSUTORI TOSHIO
IPC: F16D1/091
Filed: 1978-03-17
Abstract: PURPOSE: To lighten the concentration of stress of a fitting end portion, by forming a specified taper surface to an outer circumferential surface of a shaft opposite to an inner surface of an end portion of a boss, in a device that connects the shaft and the boss in a close-fit shape.  
     CONSTITUTION: In a fitting shaft coupling that closely fits a boss 1 and a shaft 2, a taper surface 5 is formed to the fitting end portion C, an outer circumferential surface contacting with an inner surface of an end portion of the boss 1 in the shaft 2. The taper surface 5 is formed in a tapered shape so that the quantity of interference L be reduced with approach to the end portion of the boss 1 before connection, and the width W is selected within a range that high stress is generated at the fitting end portion C. Consequently, when the boss 1 is connected to the shaft 2 an outer circumferential surface of the shaft 2 and the inner surface of the boss 1 are strongly joined by interference, and the taper surface 5 of the shaft 2 and the inner surface of the boss 1 contact under a low surface pressure condition. Thus, the concentration of stress can be lightened because high stress is not generated at the fitting end portion C.

Title: Learning control method
Inventor: ADACHI MASAO
IPC: G06F9/06
Filed: 1993-02-19
Abstract: PURPOSE:To automatically design a control algorithm at a higher speed by performing the double freedom degree control, i.e., the feedforward control and the feedback control in order to compensate the influences dependent nonlinearly on the high speed responsiveness to a target temperature and the state of this temperature and to keep a stable control state respectively. CONSTITUTION:A feedforward manipulated valiable 14 is calculated by a neural network according to the target temperature distribution 11 of a wafer 31 together with a feedback manipulated variable 17 of deviation 16 between the target temperature at the measuring point of the distribution 11 and a measured temperature. Then, a feedback controlled variable 18 is calculated from the information on similarity to the past experiences acquired through the temperature control of the wafer 31. A ring of these three variables 14, 17 and 18 is defined as a manipulated variable 13 for temperature control of the wafer 31. Thus, it is possible to compensate the influences dependent nonlinearly on the high speed responsiveness to the target temperature and the state of the target temperature by the feedforward control and to keep a stable control state by the feedback control respectively. So that the design of a control algorithm is facilitated.

Title: Turbine blade
Inventor: AKUSERU ROZUMAN
IPC: F01D5/28
Filed: 1984-02-20
Abstract: A hot gas impinged turbine blade suitable for use under super-heated gas operating conditions has a hollow ceramic blade member and an inner metal support core extending substantially radially through the hollow blade member and having a radially outer widened support head. The support head has radially inner surfaces against which the ceramic blade member supports itself in a radial direction on both sides of the head. The radially inner surfaces of the head are inclined at an angle to the turbine axis so as to form a wedge or key forming a dovetail type connection with respectively inclined surfaces of the ceramic blade member. This dovetail type connection causes a compressive stress on the ceramic blade member during operation, whereby an optimal stress distribution is achieved in the ceramic blade member.

Title: Device for removing floating matter on liquid surface
Inventor: TAKANO FUMIO
IPC: C02F1/40
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To automatically move the level of a suction end and to surely remove and separate floating matter on the surface of liquid by vertically moving a cylindrical floating body floating out the surface of liquid with the vertical movement of the surface of the liquid in a bottomed cylindrical vessel associated with the operation of an impurity forced feeding pump. SOLUTION: When a device for removing suspended matter on liquid 1 is thrown into liquid in a tank K and is submerged, even an upper end 2A of a bottomed cylindrical vessel 2 is submerged in the liquid and the liquid gradually enters the inside of the bottomed cylindrical vessel 2 to float the cylindrical floating body 3 on the surface of the liquid through an air layer. Then, a notch part 9 of the cylindrical floating body 3 is projected form the surface of the liquid and an opening 8 of the cylindrical floating body 3 is abutted on a stopper 11 to stop the rising of the cylindrical floating body 3. In this state, an impurity forcibly feeding pump 15 is started to suck the liquid into an inner space S from the notch part 9.  Then, the vertical movement of the cylindrical floating body 3 is repeated to suck a liquid layer part near the surface of the liquid into the inner space S together with suspended matter, which is removed from the surface of the liquid.

Title: Joy stick device for graphic display device
Inventor: HIROSE SADAKI
IPC: G06F3/038
Filed: 1983-02-25
Abstract: PURPOSE:To improve the operability of a joy stick and control point movement speedily and accurately by providing the joy stick with a switch means for switching a point movement mode between two fast and slow stages of analog feed and step feed. CONSTITUTION:When the stick 1 is operated in analog feed mode and an enable button 6 is pressed, movable pieces of variable resistors 2 and 3 move according to the direction and inclination of the pressing operation. Then, analog voltages indicating the X and Y coordinates of a target point are converted by A/D converters 4 and 5 into digital values, which are stored in point registers 12 and 13 through distributors 8 and 9 and OR gates 10 and 11. When a fine adjustment of the point position is made, a changeover button 7 is pressed to set the step feed mode. When the stick is operated, analog output voltages are converted similarly by the A/D converters 4 and 5 into digital signals, which are stored in detection registers 16 and 17 for the stick operation direction. Their contents are compared with the X and Y coordinates of the neutral position of the stick by comparators 20 and 21 to detect the direction of the stick operation.

Title: Caster with stopper
Inventor: KOBAYASHI HIDEFUMI
IPC: B60B33/00
Filed: 1979-03-16
Abstract: PURPOSE: To reliably control an swing pivoting motion of a caster by turning a brake pedal.  
     CONSTITUTION: A pivoting caster is braked such that, as a result of a brake pedal 15 being pressed downward, a cam lead surface is gradually pulled away from a cam control 11, and a cam lead surface 17b, whose rotation radius is smaller than that of the cam lead surface 17a, is brought into press contact with the cam contact 11. Since the pedal 15 and a slide pin 13 are pressed in the direction of an arrow A by a spring 14, the slide pin 13 moves gradually forward together with the pedal 15 by a distance of a cam lead corresponding to the cam lead (difference in a rotation radius), and the end thereof hooks in a hook groove 18 in a support yoke 1. Said hooking controls an oscillating pivoting motion of the support yoke 1, and simultaneously, a hooking part 15b located at a bottom surface of the pedal 15 comes in contact with a bottom surface of a support member 9, whereby the rotation is controlled and an swing-braking state is self-sustained. As a result, the caster functions as a non-pivoting caster in such a condition as keeping the caster facing toward the straight forward direction.

Abstract: PURPOSE: To obtain high withstand voltage of a semiconductor device even if the depth of a mesa is formed shallowly by reducing the depth of a guard ring region formed at the mesa lower than the first region.  
     CONSTITUTION: A p type diffused layer 2A and a p type diffused layer 24A for surrounding at a predetermined distance from the layer 2A the layer 2A are formed on an N type Si substrate 1, the surface of the layer 24A is lightly etched, and the surface layer is removed. Then, the layer 2A is further diffused in larger depth to form the first region 2. At this time the layer 24A is diffused to form a guard ring region 24. There occurs a difference in the diffusing depths between the region 2 and the region 24. Then, the region 24 is etched to form a mesa 3. When the region 24 is thus formed shallowly, the depth of the mesa 3 can be reduced, thereby obtaining a diode having a desired high withstand voltage.
