Title: C-shaped press fitting system with taper
Inventor: JOHN KUUIMAN
IPC: H01R13/646
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To minimize deterioration of the performance due to a return loss by pressing a C-shaped tapered spring into a fitting part to cause the maximum contact pressure near a boundary between the spring and the fitting part. SOLUTION: A coaxial connector 10 has an end section 12 formed of high strength spring material including beryllium copper. The end section 12 is formed into a tapered tubular shape to be hollow inside, with one slot 14. As a result, the end section 12 is formed into a tapered C-shaped. In the end section 12 defined as a C-shaped fitting spring, when inserted in a fitting part 20, spring force is caused by the force of a tapered spring to gradually increase press-in force. The end section 12, when fitted in the fitting part, has strong spring contact. The maximum contact pressure occurs near a boundary between the end section and the fitting part 20.

IPC: B23Q7/04
Filed: 1981-03-11
Abstract: PURPOSE:To improve safety by preventing the relative movement of a handle caused when a wrist is solely rotated, through the control of servomotors. CONSTITUTION:With a servomotor 12 stopped, a servomotor 11 is solely operated to revolve the wrist 21 around an axis 20. Consequently, the handle 23 is also revolved, because a planetary gear mechanism has been formed of bevel gears 67 and 69. Therefore, by operating also the servomotor 12 simultaneously with the operation of the servomotor 11 so that a shaft 66 is rotated in the same direction and at the same rotational speed as a hollow shaft 65, no relative rotation is caused between the bevel gears 67 and 69, and the handle 23 is prevented from revolving. Accordingly, safety improves.

Title: Method and equipment for inspecting surface of semiconductor silicon bare wafer
Inventor: MASAZUMI HANAE
IPC: G01N21/94
Filed: 1995-02-22
Abstract: PURPOSE: To detect a recessed part formed in the main surface of a semiconductor silicon bare wafer, in discrimination from a flaw and a foreign substance, by discriminating a convergent laser light out of reflected laser lights from the main surface. CONSTITUTION: A bare wafer 2 is set on a table 1 and made stable by vacuum suction. A laser light Pi is cast on the main surface of this wafer 2 from a laser light casting unit 3 and a laser light detector 4 detects a reflected laser light Po therefrom and delivers an output signal Px corresponding to the detection. Since the laser light Po from a recessed part having a prescribed radius of curvature is convergent, on the occasion, it has a stronger intensity than a reflected scattered light from a flaw or a foreign substance and can be discriminated distinctly. A comparator 5 receiving the signal Px as an input compares it with a set value of a reflected laser light category setting unit, discriminates the output signal corresponding to a reflecting laser light category, as a voltage value, and counts and displays it according to this category.  According to this constitution, it is possible to discriminate the recessed part from the flaw and the foreign substance and to detect it, simply and mechanically.

Abstract: PURPOSE: To exercise easy and accurate control over the amount of injected oxygen by providing an oxygen ion conductive solid-state electrolyte element at the tip of an oxygen injector and by controlling a current flowing through this element.  
     CONSTITUTION: Oxygen injection part 1, equipped with oxygen-ion conductive solid-state electrolyte element (called a solid electrolyte hereafter) 3 at its tip, is dipped in liquid metal sodium 6 being held by stainless pipe 5. Then, DC voltage generator 11 gives a difference in potential across solid-state electrolyte 3 and liquid metal sodium 6 and platinum porous electrode 7 are set to positive and negative polarities respectively. Consequently, oxygen gas led in from the outside of oxygen injection part 1 is changed by platinum porous electrode 7 into oxygen ions, which are injected into liquid metal sodium 6 and at the same time, charges are carried. Then, a current flows through a closed circuit extending from DC voltage generator 11 to connection cord 16 and its intensity is determined by the difference in potential across DC voltage generator 11, so that the amount of injected oxygen can be controlled by adjusting variable resistor 15.

Abstract: PURPOSE:To make effective values roughly the same and to decrease a driving voltage by setting the min. voltage impressed between liquid crystal electrodes at a specific value in association with the driving voltage and duty. CONSTITUTION:The min. voltage to be impressed between liquid crystal electrodes in the stage of time-divided driving, as designated as x>1 is set at x/ (N1/2+1)XV0 where a driving voltage is designated as V0 and a duty as 1/N. If the duty 1/N is now made to 1/16, a biasing ratio is 1/5(=161/2+1) in the coventional voltage averaging method and the min. voltage of the impressed voltage is 1/5XV0.

If X is larger than 1, for example, x=1.2, the biasing ratio is 1.2/5 and the coefft. alpha' is [(a<2>+ X(N-1)/N]1/2/a=0.33. Therefore, the driving voltage is 1.6/0.33 4.8V to obtain the same effective value, thus the driving voltage decreases by about 5%.
