Title: Combustion chamber for internal combustion engines
Inventor: MELCHIOR J
IPC: F02C7/00
Filed: 1973-04-02
Abstract: A Diesel engine equipped with such a combustion chamber is supplied, on one head with fuel, and on the other hand at the same time by exhaust gases emerging from the engine and by fresh air taken through a by-pass pipe at the outlet from the compressor of the turbo-compressor unit. The combustion chamber has a tubular element with a closed end and an open end, at least one fuel injector located towards the closed end, and a primary air intake for leading fresh air into the tubular element at a combustion zone near its closed end. The combustion chamber has also an exhaust gas intake to introduce the exhaust gases into the tubular element at a mixing zone near its open end, this being done with minimum load loss and along an orientation slightly inclined with respect to the axis of the tubular element towards its open end and a secondary air intake for leading fresh air into the tubular element at the mixing zone, this being done perpendicularly to the flow of the introduced exhaust gases, and so that the flow of secondary air is opposed by the flow of the exhaust gases, by interaction of the jets.

Title: Optical deflector
Inventor: SHIOTANI KOHEI
IPC: H02P6/08
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of an optical deflector. SOLUTION: At the time of image formation, a power supply selection means 26 is subjected to PLL control for turning a motor M at a constant speed by applying a DC power supply voltage thereby operating a driver IC 24. At the time of standby, a voltage generation means 28 applies a voltage to each stator coil 13U, 13V and 13W through the driver IC 24 and regulates the AC voltage of an AC power supply to have the amplitude and phase identical to those of an AC voltage lower than that at the time of image formation. Upon finishing the regulation, the power supply selection means 26 interrupts application of the power supply voltage to the driver IC 24 and applies a regulated AC voltage to each stator coil 13U, 13V and 13W.

Title: Hydrodynamic bearing type motor and scanner motor for driving polygon mirror
Inventor: HAYASHI KUNIO
IPC: H02K5/167
Filed: 1995-01-26
Abstract: PURPOSE: To automatically suppress vibration induced in a rotor assembly in the axial direction through rotation thereof. CONSTITUTION: If a rotor assembly 36, rotating while levitating, descends due to disturbance, the gap 61 between the lower end part 35a of a rotary shaft 35 and a gas conduction hole 58 is decreased. Consequently, the rate of air flowing into a bearing clearance 39 through the gas conduction hole 58 is decreased and the pressure on the under side of the bearing clearance 39 decreases and the pressure on the upper side increases relatively thus producing a force for pulling up the rotor assembly 36. On the contrary, when the rotor assembly 36 ascends, the gap 61 is increased and since the rate of air flowing into a bearing clearance 39 through the gas conduction hole 58 is decreased, the pressure on the under side of the bearing clearance 39 increases and the pressure on the upper side decreases relatively. Consequently, a downward force acts on the rotor assembly 36.

Title: Magnetic head slider
Inventor: WAKATSUKI KOSAKU
IPC: G11B21/21
Filed: 1990-01-22
Abstract: PURPOSE:To prevent the damage of a magnetic disk due to dust by using rail outer edges having a skew angle of a magnetic head slider to exclude fine particles of dust larger than the floating gap between the magnetic head slider and the magnetic disk. CONSTITUTION:A magnetic head slider 1 has tapered parts 2, which are floating surfaces to bring about a gas bearing action, and flat rail parts 3 so that they face the magnetic disk, and tapered parts 2 and rail inner edges 4 of flat rail parts 3 are approximately parallel with the tangential velocity vector line of the rotating magnetic disk, and rail outer edges 5 are arranged at a skew angle 6 to widen toward the gas outflow side from the gas inflow side. Whichever side the magnetic head slider is moved to, fine particles of dust or the like on the magnetic recording medium which are larger than the floating gap collide with rail outer edges and are excluded because rail outer edges always precede the tapered parts. Thus, the magnetic disk is prevented from being damaged by the dust penetrating from tapered parts.

Title: Axial-flow type noiseless discharge excitation gas laser device
Inventor: KANEHARA YOSHIHIDE
IPC: H01S3/0975
Filed: 1984-01-26
Abstract: PURPOSE:To enable laser beams of good quality to be outputted by uniformity of a discharge space obtained by AC-voltage impressing on an electrode by a method wherein the titled device is so constructed that a discharge tube made of dielectric is thin at the center of the electrode and becomes thicker as distant from the center. CONSTITUTION:This device is so constructed that the discharge tube 1 of approximately cylindrical form made of dielectric is thin at the centers of the electrodes 3A and 3B and becomes thicker as distant from the center. A part 10 of the discharge tube 1 thus constructed is larger than a part 11 in the electrostatic capacitance due to the dielectric constituting the discharge tube; thereby, the impedance to AC increases. Therefore, when an AC voltage is impressed across the electrodes 3A and 3B of this discharge tube 1 from an AC power source 4, the discharge distance in the part 10 becomes longer than that in the part 11, thereby increasing the discharge voltage; however, the current of a noiseless discharge 5 becomes uniform, and a uniform discharge space can be obtained.

Abstract: PURPOSE:To maintain the continuity of characters while suppressing an increase in the capacity of outline data by providing information which specifies whether character outline coordinates are described as relative coordinates or absolute coordinates. CONSTITUTION:A CPU 101, i.e., central processing unit controls the whole device and performs arithmetic processing and a ROM 102, i.e., read-only memory is a storage area for a system start program, character patterns, data, etc. Then it is decided whether coordinate data in a storage means which form the shapes of characters include relative coordinates or absolute coordinates to derive coordinate values as relative coordinates based upon coordinates of a last point when the relative coordinates are decided or as absolute coordinates based upon specific coordinates as an origin irrelevantly to the coordinates of the last point when the absolute coordinates are judged. Thus, the information for discriminating between the relative coordinate data and absolute coordinate data is provided and then only coordinate values which need to have continuity are described as absolute coordinates.

Title: Manufacture of high dielectric-strength high-speed diode
Inventor: OSADA KATSUHIKO
IPC: H01L29/868
Filed: 1982-01-27
Abstract: PURPOSE:To improve yield on the manufacture of the high-speed high dielectric- strength diode by increasing the diffusion surface concentratin of phosphorus up to specific concentration or more and gettering gold by phosphorus. CONSTITUTION:An N<+> layer 3 is formed by diffusing phosphorus from one surface of an N type Si board 1 and a P<+> layer 4 by diffusing phosphorus from the other surface. The diffusion surface concentration of phosphorus is made 5X10<20> number/cm<2> at that time. Consequently, when the surface concentration of the diffusion of phosphorus is increased and diffusion depth is deepened, gold concentrating into a layer 6 in the vicinity of a junction between a layer 2 and the layer 3 intrudes into the phosphorus diffusion layer 3 by the gettering action of phosphorus in the gold diffusion process of the next process, and the formation of a new P<+> layer can be prevented. Accordingly, a P layer is formed between the N<+> layer and an N layer by the concentration of gold atoms, and  the generation of the cause of defective forward characteristics can be obstructed, particularly, yield in the manufacture of the high-speed high dielectric- strength diode can be improved.
