Title: Crank shaft supporting device of multi-cylinder internal combustion engine
Inventor: FUKUO KOICHI
IPC: F02F7/00
Filed: 1989-10-30
Abstract: PURPOSE:To materialize an engine which is light in weight by joining a bridge member extending to the axial direction of a crank shaft monolithically with the lower surfaces of plural bearing caps, and thereby making up the bridge member and each cap from a light alloy and an iron alloy respectively. CONSTITUTION:When an internal combustion engine is in operation, a crank shaft Sc is subjected to both bending and twisting moments in the Y-Y, and X-X directions. In this case, plural bearing caps 11 are made up from an iron alloy with comparatively high stiffness and high strength, and are furthermore, firmly fixed onto a journal wall 7. In addition, they are relatively and integrally connected together via a bridge member 17 so that the bearing caps are reinforced with one another. This permits these caps to sufficiently withstand external force against the crank shaft Sc. Besides, the caps includes a bearing half section 9 for the crank shaft Sc, and the bearing caps 11 and the bridge member 17 are made up from an iron alloy and a light alloy which is comparatively high in a coefficient of thermal expansion, relatively wherein the caps are liable to become high in temperature when the engine is in operation and the member is comparatively low in temperature since it is spaced from the bearing half section 9.

Title: Code detection device
Inventor: ONO SHINJI
IPC: G11B20/12
Filed: 1990-10-23
Abstract: PURPOSE:To enable write/read of information to be performed efficiently by measuring and memorizing an interval of a detection signal on a memory medium and achieving an interval for allowing for passage of only a code detection signal based on the difference. CONSTITUTION:A sector length difference measuring circuit 11 obtains a difference from a standard length of a sector length standard value circuit 12 based on a signal of a sector mark detection circuit 1 and memorizes each difference into a memory circuit 13 with a sector mark position as an address. A sector mark detection gate generation circuit 20 increases or decreases the standard length according to each differential value and then obtains a width of a gate signal. Therefore, no erroneous sector mark detection signal is transmitted, thus preventing write/read error for a memory disk having track of poor roundness and enabling access time to be reduced and efficiency to be improved.
Patent JP-H09126477-A (JP)
Title: Overturn-detecting switch mechanism
Inventor: NISHIWAKI FUMITOSHI
IPC: F24C7/08
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous operation in the detecting state of an overturn detecting switch. SOLUTION: When the tip of an actuator 13 is oppositely brought into contact with the placing surface, the actuator 13 is displaced to the placing detecting position against a coiled spring 17, thereby making it possible to close a switch 12. On the other hand, when the end of the actuator 13 is separated from the placing surface, the actuator 13 is urged by the spring 17, displaced to the overturn detecting position, and the overturn is detected by opening the switch 12. However, if the actuator 13 is merely separated vertically from the placing surface, the resetting of the actuator 13 to the placing detecting position is allowed, but since the actuator 13 is obliquely crossed with respect to the placing surface if it is actually overturned, the resetting to the placing detecting position is prevented by a guide cylinder 18.  Thus, the malfunction of closing the switch 12 is prevented even though there is no overturn if an article is brought into contact with the end of the actuator 13 even if the switch 12 is once opened by detecting the overturn.

Abstract: PROBLEM TO BE SOLVED: To reduce NOx at a burning stage by installing a burner body for supplying the air to an end of a radiant tube, allowing a fuel supply tube to protrude in a radiant tube direction in the burner body and installing a primary combustion cylinder forward of the supply tube. SOLUTION: As shown by an arrow, part of the air supplied from an air supply unit 3 is fed into a primary combustion cylinder 5, and the residue flows at an outside of the cylinder 5. Meanwhile, fuel injected from a fuel supply tube 4 is ignited by an ignition source 6. Thus, primary combustion with partial air is started, the air is fed into the cylinder 5, and the primary combustion is proceeded while the air flows in the cylinder 5. The combustion gas in which predetermined primary combustion is executed is discharged from the cylinder 5, mixed with the air fed at the outside of the cylinder 5, and secondarily burnt. In this case, specifications such as diameter and length of the cylinder 5, and a distance from an end of the tube 4 are suitably set to conduct predetermined combustion in the cylinder 5.

Title: Filter for power converter
Inventor: MIYAKE WATARU
IPC: H02M7/12
Filed: 1992-09-29
Abstract: PURPOSE:To allow acquisition of new operation results every time when a high speed operation system is employed by constituting a filter for decreasing a frequency component two times of the number of phases of AC voltage and attenuating the pulsating components produced through rectification. CONSTITUTION:The filter comprises an operational amplifier 30, a resistor 31, and a capacitor 32. The filter receives, at an input terminal thereof, DC voltage or DC current from a converter and attenuates pulsating components produced through rectification to produce an output wherein the gain decreases in the vicinity of characteristic frequency omegan and in other frequency region the gain is 0 dB. i.e., the ratio of output to input equals to 1. Resistance and capacitance of the resistor 31 and capacitor 32 are selected such that the characteristic frequency omegan is doubled. Consequently, pulsating components produced through rectification can be attenuated in a feedback value through the use of a voltage detector 16 or a current detector 15 and a good stabilized control, scarcely susceptible to pulsation, can be realized resulting in a high response control system.

Title: Method and device for approximating line picture
Inventor: OKAZAKI SHINICHIRO
IPC: G06T5/00
Filed: 1989-10-31
Abstract: PURPOSE:To approximate inputted sequence-of-points to N-pieces of definite approximate shapes by over-dividing the inputted sequence-of-points into sections more than the number of pieces N of the predetermined approximate shapes and approximating the inputted sequence-of-points by combining over-divided sections so that an approximation error becomes minimum. CONSTITUTION:When N-pieces of the approximate shapes are given, the approximated sequence-of-points is divided into plural linear direction sections which have linear average direction change and in addition, whose average error from linearity is below a threshold T by using the value of the direction of a direction picture in the approximated sequence-of-points. This linear direction section dividing processing is repeated as changing the threshold T until the number of the linear direction sections obtained by this becomes more than N. Then, the neighboring plural linear direction sections are collected together, and the combination of the linear direction sections to make N-pieces of integrated approximate section is generated, and the integrated approximate sequence-of-points of the minimum approximation error E is obtained from among the obtained integrated approximate sequence-of-points of M-1CN-1-kinds, and the approximation error E and the shape parameter are outputted. Thus, an inputted line picture can be segment-circular arc approximated to N-pieces of the approximate shapes.
