Title: Ignition pulse amplifier of thyristor
Inventor: HAYASHI SHINICHIROU
IPC: H03K17/73
Filed: 1980-05-19
Abstract: PURPOSE:To obtain the ignition amplifier of thyristor having superior performance and consuming electric power thereof being small by a method wherein a reverse voltage generated in the tertiary winding is applied to the gate of the thyristor as a positive ignition pulse. CONSTITUTION:When a signal (a) is inputted to an input terminal 10, a voltage (b) is generated in respective windings 5, 13 and 14 of a pulse transformer 12. A positive voltage generated in the second winding 13 is applied to the gate of the thyristor 1 through the first diode 3 when the transistor 12 is made to ON, and a negative voltage generated in the tertiary winding 14 is applied through the second diode 15 when the transistor is made to OFF respectively. Accordingly the gate signal becomes as a continuous DC signal as shown with the figure (c), and when frequency of the signal voltage to make the transistor 9 to ON and OFF is made to high, the section of core and number of winding of the pulse transistor 12 are decreased to enable the miniaturization, and because electric power is not consumed during OFF time of the transistor 9 in the period when the ignition pulse being outputted, economization of consuming electric power in the ignition amplifier can be attained.

Title: Manufacture of ferroboron of low aluminum content and high boron content
Inventor: UOTANI SUSUMU
IPC: C22C38/00
Filed: 1984-04-06
Abstract: PURPOSE:To form the titled ferroboron without the buldging of a hearth by changing an iron-contg. raw material into an electric furnace and melting, and then charging a boron-contg. raw material and a carbonaceous reducing agent and melt-reducing. CONSTITUTION:An iorn-contg. raw material (mild steel scrap, shavings, etc.) is charged into an electric furnace, after finishing the tapping, and melted. A boron-contg. raw material (boric anhydride, borax, etc.) and a carbonaceous reducing agent (coke, coal, etc.) are blended, mixed, and charged into the melt bath. The boron is reduced, and the formed boron is alloyed with iron to form a ferroboron bath contg. at least about 20% boron. The melt is extracted from the electric furnace. Consequently, even when B4C is deposited on the hearth, a part of the deposit is decomposed by controlling the mixing proportion of molten iron or iron oxide and the carbonaceous material necessary for reducing the iron and the iron oxide. Since the formed boron is absorbed by the molten iron, the buldging of the hearth is prevented.

Title: Burner
Inventor: IWAMURA KAZUYUKI
IPC: F23D11/24
Filed: 1986-03-26
Abstract: PURPOSE:To make uniform the temperature of the bottom face of a combustion cylinder and prevent accumulation of oil and evaporate the fuel completely by providing a heat pipe on the inner bottom face of a combustion cylinder. CONSTITUTION:When a fuel is jetted out of a fuel nozzle 4 into a combustion cylinder 1, the air conveyed under pressure to a carburetor cylinder 2 from a blower 8 and the air coming at the same time out of an air blow-out opening 3 in swirl are mixed with the fuel. The mixture starts combustion after ignition by an ignition plug 6. Even when the combustion amount is changed, nonuniform temperature does not occur at the bottom face of the combustion cylinder and since high temperature is always kept, oil does not stay at the inner bottom face and the combustion is stable. Further, because no oil stays at the inner bottom face, white smoke and unpleasant odor are eliminated which otherwise would be produced when the combustion stops.

Title: Heating of glass gob and gob pan transfer apparatus
Inventor: NAKAHAMA MASATO
IPC: C03B11/00
Filed: 1994-03-10
Abstract: PURPOSE:To obtain an optical element free from astigmatism and tendency by acing an axially symmetrical glass gob on a gob pan and softening the gob by heating in an axially symmetrical state or a state extremely close to axial symmetry. CONSTITUTION:An axially symmetrical glass gob is heated on a gob pan in an axially symmetrical state or a state extremely close to axial symmetry. This heating method for the glass gob enables the heating of a gob in axially symmetrical state by suppressing the heat conduction to the gob pan from a member contacting with the outer circumference of the gob pan, thereby heating the gob pan in axially symmetrical state. A glass gob as a raw material for an axially symmetrical optical element such as a convex lens and a concave lens can uniformly be flowed with a press by generating symmetrical sag of the glass gob. Accordingly, an excellent optical element free from sink and tendincy can be produced by the uniform sharinkage of the following shrinking stage of the glass.

Title: Supercharge device of engine
Inventor: AKAGI YUUJI
IPC: F02B33/36
Filed: 1984-04-04
Abstract: PURPOSE:To prevent a change of pressure, generated in an engine air intake system, from being spread into work chambers of a pump, by forming chambers, which absorb the change of pressure, in a space inside a rotor of the air pump. CONSTITUTION:This supercharger provides a condition such that intake air is compressed in work chambers 16 while supercharge pressure is generated in accumulator chambers 12 in a rotor 6 by communicating with the intake passage of an engine through a discharge air hole 21. If the accumulator chamber is moved by rotating the rotor, air in the work chamber 16 and that in the preceding side is allowed to flow while being compressed into the accumulator chamber through a communication path 19 provided in a side housing. If the accumulator chamber is opened to the discharge air hole 21 by further rotating the rotor, high pressure air is released to the intake passage of the engine only by the amount of differential pressure between the pressure in the accumulator chamber and the supercharge pressure.

Title: Controller for pulse width modulation solenoid
Inventor: FURUKAWA HIDEO
IPC: F16H61/04
Filed: 1995-03-02
Abstract: PURPOSE: To minimize increase in the number of voltage memory circuits by detecting the conduction current of at least two pulse width modulation solenoids and subjecting the detected pulse width to A/D conversion thereby shifting the drive start timing of two solenoids by a predetermined interval. CONSTITUTION: A CPU 17 determines command values for linear solenoids SL3, SL4 (only SL3 is shown) in the form of a duty ratio and delivers a drive pulse to the base terminal of a transistor TR. In response to the drive pulse, the transistor TR is turned on to conduct the solenoid SL3. Voltage across the solenoid SL3, proportional to the conduction current, is fed to an operational amplifier 23 for amplification which delivers an output to an A/D converter 22. The A/D conversion totally requires 0.03ms with a time lag Td of 0.03ms, i.e., a pulse B rises with a time lag of 0.03ms behind the rising time of pulse train A. A converted value is inputted to an RAM 19 and converted through the CPU 17 into a current value and the difference from a target value is multiplied by a feedback gain thus correcting the command value.
