Patent JP-H07153940-A (JP)
Title: Manufacture of field-effect transistor
Inventor: ONODA YASUO
IPC: H01L29/78
Filed: 1993-11-30
Abstract: PURPOSE:To provide a manufacturing method of transistors, in which the performance of each transistor on the same substrate and the performance of the transistors among production lots are kept constant at all times CONSTITUTION:A polycrystalline silicon film formed onto a semiconductor substrate 1 through a gate oxide film 2 is removed selectively, and a first polycrystalline silicon film is left on a region, in which a channel is formed, and second polycrystalline silicon films in specified width on regions as low- concentration impurity regions through the first polycrystalline silicon film and specified clearances. Ions for shaping an N<-> region are implanted while using these polycrystalline silicon films as masks, the clearances are buried with a silicon oxide film 6 through oxidation, and ions 9 for forming N<+> regions are implanted while employing an obtained gate electrode 8 and the silicon oxide film 6 as masks.

Title: Air conditioner
Inventor: TAKEDA MASAAKI
IPC: F24F11/04
Filed: 1987-11-27
Abstract: PURPOSE:To provide a comfortable working space and comfortable circumstance by a method wherein an air speed changing-over mechanism capable of changing-over either an air speed or an amount of air at a blowing port to more than three stages is provided and a variation between a section taking a quite minimum value and another section taking a quite minimum value is controlled to have a simple reduction or a simple increment. CONSTITUTION:An air blowing port 6 and an air speed changing-over mechanism 8 capable of changing over an air speed and an amount of air at the air blowing port 6 more than three stages are provided. The air speed changing-over mechanism 8 is controlled in such a way as a variation of air speed between a section taking a minimum air speed value and another section taking a minimum air speed value has a simple reduction or a simple increment. However, if a position of the air blowing port 6 is too far from a working table 7, an air speed near the working table 7 where a person is present is hardly kept at a proper value and additionally an air stream once fed out becomes easily a disturbed flow, so that a position of the blowing port 6 is set near the working table 7. An air direction is set to face against a person's face so as to prohibit some documents on the working table 7 from being disturbed. With this arrangement, a variation of the air speed shows little random characteristic or an accidental characteristic and then a comfortable and nice condition can be attained in an environment where the person works.

Title: Spiral-bar-shaped screw and bow rudder for use in half-submerged catamaran
Inventor: ETO TADAKATSU
IPC: B63H1/12
Filed: 1991-09-02
Abstract: PURPOSE:To enhance the propulsion efficiency of a ship pusher and the steering function of a half-submerged catamaran whose hulls are very small in width. CONSTITUTION:A screw which comprises a rotating shaft in the form of a spiral bar with an irregularly machined surface, and right, left and lower hull barrel front portions are all provided with variable angle portions and are operated simultaneously with a conventional stern rudder. Because the rates of generation of turbulent flow caused by stirring and a backward jet are very low, energy losses resulting from them are reduced and deflection of fluid pressure on the surface of the screw is prevented structurally. In addition, a dimple effect is available from the irregular machining of the surface of the rotating shaft, suppressing the peeling phenomenon of fluids. Application of this bow rudder significantly enhances steering functions as in a steep turn during navigation at high speeds.

Title: Package for optical semiconductor module
Inventor: MARUYAMA HIDEKI
IPC: H04B10/07
Filed: 1993-12-01
Abstract: PURPOSE:To stably fix an optical system to a package body by adhering a lens holder via a specific buffer member to the package body. CONSTITUTION:This package contains an optical semiconductor device 2 and has the lens holder 6 which optically connects the device 2 and an optical fiber 3 and includes an aspherical lens 9. The buffer member 10 consisting of a material having the coefft. of expansion equal to the coefft. of expansion of the lens holder 6 is interposed between the lens holder 6 and the package body 1 in such a case. The lens holder 6 and the buffer member 10 are then brazed or welded. As a result, the thermal stresses generated in the lens holder 6 and the buffer member 10 are equaled and the adhesive surface of the lens holder 6 and the buffer member 10 is no longer moved in an outer peripheral direction and, therefore, tensile stress does not act on the aspherical lens 9 any more and the crack is no longer generated in the aspherical lens 9. The optical system is thus stably fixed to the package body.

Title: Brushless motor
Inventor: UJO TATSUZO
IPC: H02K29/00
Filed: 1986-12-19
Abstract: PURPOSE:To restrain the torque ripple of the title motor to a small value, by a method wherein at least three protrusions are provided on the rotor yoke side of a stator yoke with the pitch of electric phase angle of 60 deg.. CONSTITUTION:Three protrusions 20, having radial lengths, are provided on a stator yoke 1 with the interval of a mechanical phase angle (the electric angle of 60 deg.) in the circumferential direction of the yoke 1. When a rotor yoke 4 is rotated, flux is changed at the position of the protrusion 20 every time when one pole of a multipole magnet 7, attached to the rotor yoke 4, passes through the positional area of a corresponding protrusion 20 whereby cogging torque is generated. Such magnetic change is generated at the position of the multiple poles of the magnet 7, therefore, the number of times of generating the change of torque or torque ripple becomes three times of the number of poles of the magnet 7. Such a cogging torque is applied on the rotor yoke 4 as a loss torque whereby a generating torque may be eliminated and the torque ripple may be removed effectively.

Filed: 1994-11-14
Abstract: PURPOSE: To provide a semiconductor device having a high heat conductivity by providing a layer of a diamondlike material which forms a thermal conductor for removing heat from a metal contact layer and a device. CONSTITUTION: A layer 50 of a diamond or diamondlike material is applied to the surface of a contact layer 40 and the exposed upper end part (light emitting window 45) of a mirror stack.

Abstract: PURPOSE: To attain optimum control corresponding to flying conditions with simple constitution by detecting the altitude and speed of an airframe to perform gain control with an approximate function such as a quadratic-equilateral hyperbola function in an autopilot in guidance and control of a flying body. CONSTITUTION: With initial altitude input 13 and initial speed input 14, optimum function generators 11a-11h are selected by dynamic pressure band switches 12a-12d.

The angular velocity and acceleration of an airframe are measured by a rate gyro 8 and an accelerometer 9 and fed back. The altitude and speed of the airframe are detected and computed by an inertia reference device 10, and the function generator selected on the basis of this output is gain-controlled with an approximate function such as a quadratic-equilateral hyperbola function. Optimum control corresponding to flying conditions can therefore be obtained with simple constitution.
