IPC: G10D9/04
Filed: 1989-11-08
Abstract: PURPOSE: To obtain a rotary type acoustic passage selector valve which does not require a lubricant by providing this valve with a dynamic energizing means for maintaining the hermetic overlap between a casing hole and the end of a rotor passage. CONSTITUTION: A compression spring 80 brings the outer surface 92 of a rotor head part 90 into light contact with the inner surface 126 of a casing end plate 120 and maintains the outer tapered surface 46 of a rotor tapered part 41 in light contact with the inner flank 18 of the casing 10. The contact surface functions as the rotation supporting surface facing a rotor assembly 40 with respect to the casing 10. The spring 80 is weak in the force and the assembly 40 is, therefore, rotated in the valve casing 10 to float. The leakage of sound energy and air pressure is prevented by the floating and the circular truncated cone hole 42 of the rotor is held always in the state aligned onto the circular truncated cone hole 16 of the casing and the axial line.  As the rotor 40 expands or contacts in the axial line direction, the peripheries of the rotor passages 51 and 70 are held sealed by respective O-rings 60 to 62 and the passages are likewise slid axially to the respective seats in this state.

The induction of the fuel from an auxiliary fuel passage 64a to the auxiliary compression chamber 18 precedes that to the main compression chamber 16 by an advance angle theta of an auxiliary suction slit 62 relative to a main suction slit 58. The fuel is then compressed at a small-diameter portion 22b, and is injected through a delivery valve 60 from the passage 62a. The preinjection by the small-diameter portion 22b precedes a main injection by a large-diameter portion 22a by the advance angle theta. Accordingly, the combustion in a Diesel engine may be improved.

Filed: 1987-11-18
Abstract: PURPOSE:To make sure the fitting position of a chip resistor by providing tow equal lines for branching having the length of the quarter of a transmitting signal wavelength and patterns for the chip resistor to show the fitting position of the chip resistor. CONSTITUTION:The fitting position of a chip resistor 17 has to be correctly at the distance of the quarter of the transmitting signal wavelength from a branch point 12 of two lines 13 and 14 for branching from a line 11 for a composite wave. For this reason, the chip patterns to show the fitting position of the chip resistor 17 are provided. Patterns 22 and 23 in the same shape as the 18 and 19 are provided on the positions the quarter of the transmitting signal wavelength distant from the patterns 18 and 19 for the chip resister. For this reason, when a wave to degrade a voltage standing wave ratio generated by the 18 and 19 is reflected by the patterns 22 and 23 and returned to the position of the patterns 18 and 19 for the chip resistor, a phase difference becomes a half of the transmitting signal wavelength and becomes antiphase. Therefore, the wave generated by the patterns 18 and 19 for the chip resistor can be canceled.

Filed: 1988-11-18
Abstract: PURPOSE:To adjust a brush pen pressure according to a character size to enable an especially small character to be drawn clearly by adjusting the brush pressure information of each stroke forming a character according to the size of the character to be drawn. CONSTITUTION:With the input of a character code and a magnification code from a keyboard 2 to an input port 3, a main processing part 1 starts a character forming action and reads the character code from the input port 3. Then, the main processing part 1 refers to a skeleton dictionary 4 by the read character code and reads the information of all strokes of the character code. After the completion of the reading of stroke data corresponding to all stroke numbers, a minimum value PRM of a circumscribed square of a character outputted according to a character pattern represented by accumulated joints and the magnification code is detected, and a brush pen pressure gap value (w) is obtained by referring to a brush pen pressure adjustment table 7. From the gap value (w), 'a depth of brush pen' is calculated per stroke. Control data is generated in a command generating part 9 and outputted to a brush pen plotter 11 through an output port 10 to make the plotter draw the character.

Filed: 1985-12-25
Abstract: PURPOSE:To improve the holding characteristics of charge while forming thick insulating film covering a floating gate electrode by a method wherein the insulating film is formed without etching the first and the second gate insulating film. CONSTITUTION:The impurity leading-in energy can be reduced by a protrusion 7B by leading any impurity in the main surface of a semiconductor 1 on the end of gate electrode 1 through the protrusion 7B to reduce any damage to a gate insulting film 5 (a part encircled by dotted line) on the end of gate electrode 6. In other words, said gate insulating film 5 can be formed of fine filming material to prevent any leakage of charge to be data from occuring while improving the holding characteristics of charge as well as the breakdown withstand voltage of gate insulating film 5. Furthermore, a semiconductor region 9A with impurity concentration lower than that of another semiconductor region 9 can be formed since the lead-in impurity can be reduced by the protrusion 7B. The semiconductor region 9A can avoid the shortchannel effect playing the same role as that of LDD structure.
