Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide reliable insulation by filling a cylindrical case with an insulating liquid, providing one end of the cylindrical case with a lid part comprising a sealing mechanism contacting the inside, and press-contacting a flat semiconductor element. SOLUTION: While inserted so that a protruding part 2e of a lid 2a agrees with the inside surface of a cylindrical case 1a, an O-ring 5a provided at the protruding part 2e of the lid 2a seals, thus the inside of the cylindrical case is closed. By clamping the lid 2a to a flange 1d of the cylindrical case 1a using a bolt 3a, a flat semiconductor element inside the cylindrical case 1a is pressurized by the lid 2a, providing a structure body connected in series. The press- contacting of the flat semiconductor element inside and closing of case's inside are performed at the same time by clamping the lid of the case, so the size of the case is reduced to that determined by the size of the flat semiconductor element, allowing reduction in size of a device.

CONSTITUTION:For first and second operational amplifiers 15 and 22, one terminal is connected to first and second reference voltage sources 14 corresponding to the power supply voltage, and the output terminal is connected to the bases of first and second output transistors 16 and 23. For first and second load resistors 17 and 24, the output voltages of the first and second output transistors 16 and 23 are impressed to one terminal respectively. Then, the power supply voltage and the output voltage of the first operational amplifier 15 are impressed to the other terminal, and one terminal is connected to the other input terminals of the first and second operational amplifiers 15 and 22. The first differential amplifier 18 uses a first constant current transistor 34, which is connected to the first output transistor 16 in current mirror relation, as an operating current source and uses a resistor 31 impressing the power supply voltage to one terminal as a load. Thus, the current of the initial value and the current to be changed can be linearly.

Title: Combusion camber of diesel engine
Inventor: SUZUKI MAMORU
IPC: F02B3/06
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To accelerate the mixing of fuel and air by providing a central projecting part at the bottom of a combustion chamber, a wall surface projecting part on the wall surface, a radially outwardly expanded recessed part, and an annular projecting part toward the radial inside in an opening part of the combustion chamber, and making the maximum diameter of the combustion chamber and the diameter of a piston have a specified relationship. SOLUTION: A central projecting part 1 is provided at the center of the bottom of a combustion chamber 100. Some of jet fuel 7 sprayed toward the wall surface projecting part 4 of a wall surface 3 flows to a recessed part 5 taking the wall surface projecting part 4 as a boundary, and the remaining part flows downward from the wall surface projecting part 4. The fuel which has flowed the recessed part 5 is restrained from flowing out to a squish area by an annular projecting part 6 to cause convection in the recessed part 5. The fuel becomes fine particles to be diffused over the peripheral area of the combustion chamber 100, thereby restraining diffusion to the bottom of the combustion chamber. The value obtained by dividing the maximum diameter d1 of the combustion chamber by a piston diameter D is set larger than 0.5.  Thus, after the jet fuel 7 collides with the wall, the dynamic energy of the fuel itself is lowered so that mixing is accelerated by air current.

IPC: H03M1/78
Filed: 1991-10-08
Abstract: PURPOSE:To provide the digital/analog (D/A) converter which can obtain high resolution while maintaining monotonicity without using the resistor of a high resistance ratio. CONSTITUTION:A second D/A circuit to be driven based on the digital data of high-order bits is equipped with a 2R circuit 8 composed of plural resistors.

Abstract: PURPOSE: To prevent deformation in storage and transfer by a method, wherein a vacuum envelope having a rectangular display window is constructed of an assembly of at least two ring-shaped anti-implosion bands of the same shape in a detachably superposed state, and these ring-shaped anti-implosion bands are retained by a suspension tool. CONSTITUTION: A display tube having a nearly rectangular display window 1, a conical envelope 2 and a net part 3 is provided with a nearly rectangular anti-implosion band 4, located around the display window 1. For example, even if the display tube is dropped, the danger or instantaneous implosion of the envelope 2 is reduced. Particularly, the band 4 has almost the same shape as an external shape of the window 1, and a metallic band of slightly smaller peripheral size is adopted as the anti-implosion band 4. This metallic band is heated to acquire a peripheral size larger than that of the window 1, and then cooled to enclose the window 1 by applying mechanical stress. When the display tube is suspended by a cabinet, a suspension element 5 is attached to the band 4 for stabilizing retention.
