Title: Spark gap adjusting method of spark plug and its device
Inventor: FUJITA SHIGEO
IPC: H01T21/06
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device capable of adjusting a gap size securely and effectively even if there is dispersion in the deformation resistance of grounding electrodes among individual spark plugs. SOLUTION: First of all, by applying the predetermined number of preliminary strikes to a grounding electrode of a processed spark plug with an air hammer unit 6, a gap spacing of the processed spark plug is reduced in a range not less than a targeted gap spacing. Next, the gap spacing reduction value as a result of the preliminary impacts is measured with a gap photographing and analyzing unit 7 and thereby, the number of adjusting strikes and/or striking force required to reach the targeted gap spacing is determined based on the measured result. Then, the adjusting strikes are so applied to the grounding electrode with an air hammer unit 8 using the determined number of strikes and/or striking force as to form a final gap spacing.

Title: Circuit for driving end face light emitting type led
Inventor: YAMANE KAZUO
IPC: H04B10/67
Filed: 1986-12-19
Abstract: PURPOSE:To prevent an output from being increased due to induced emission, by reducing a current value supplied for the driving of a LED by generating an output signal representing exceeding degree over a reference signal when the output signal of a light receiving monitor circuit exceeds a prescribed reference signal, from a comparator. CONSTITUTION:An end face light emitting type LED10 is constant current-driven by an input data pulse supplied via the base capacitor C1 of a transistor TR1 and a resistor R1, and emits light spontaneously. When the LED10 emitting the light spontaneously starts to move in the direction of the induced emission due to low temperature driving environment, the output light of the LED10 is increased. A signal representing the degree of increase is supplied to an operational amplifier 28 via a photodetector 22 and a low-pass filter 26, and is compared with the reference signal. The signal with a lower bias level enough to offset the increment of the output light is outputted from the operational amplifier 28, and moves the (0) level of an input data pulse string to the level, and suppresses the increase of the output light.

Title: Method for pouring molten metal of large steel ingot into continuous casting mold
Inventor: OKAMURA MASAYOSHI
IPC: B22D11/00
Filed: 1990-11-09
Abstract: PURPOSE:To efficiently pour a molten metal of a large steel ingot into a casting mold by opening a nozzle and storing the molten metal through a large diameter pouring nozzle when the pouring of molten metal is begun, then, changing over the pouring nozzle to a low speed casting pouring nozzle and pouring the molten steel in a molten steel container into a water cooled casting mold. CONSTITUTION:A sliding valve provided with a pouring nozzle 11 having a large inner diameter and a pouring nozzle for low speed casting is installed in a molten steel container and when pouring is started, opening of the nozzle and storage of the molten iron in the casting mold are performed by using a pouring nozzle large in a nozzle inner diameter. When the molten steel container is a tundish 1, the tundish can be opened easily at a time from the inner bottom side in the same opening way. After the nozzle is opened, the molten metal is poured by a large inner diameter pouring nozzle into the casting mold, therefore, the molten metal can be stored in the casting mold comparatively in a short time. Further, after the molten metal is stored, the pouring nozzle is changed over to the pouring nozzle for low speed casting and the molten metal is poured continuously as the opening of the slide valve is kept nearly full. Consequently, the nozzle is difficult to block and a large ingot can be poured efficiently.

Title: Ac-dc converter
Inventor: IKEDA SATOSHI
IPC: H02M7/06
Filed: 1994-12-09
Abstract: PURPOSE: To improve power factor of an AC-DC converter and reduce higher harmonic components of the converter and, at the same time, to improve the controllability of a pule width control circuit with a simple circuit configuration by constituting the control circuit so that the turn-off duration of a pulse signal which is used for driving a switching means can become longer when a rectified voltage is high and shorter when the voltage is low. CONSTITUTION: A pulse width control circuit 17 excites a choke coil 4 by driving a switching mean 5 at a prescribed on/off ratio when a rectified voltage Ei is low and a current signal is small, but, when the current signal reaches a current error signal Ve, limits the turn-on time of the switching means 5 so that the current signal cannot exceeds the signal Ve. Consequently, the waveform of an AC input current Ii which is obtained by smoothing the electric current I1 flowing through the coil 4 by means of an input filter 2 becomes a trapezoidal waveform. When the turn-on time of the means 5 is limited, the turn-off time of a pulse signal which is used for driving the means 5 becomes the shortest and the time ratio becomes the maximum at the the point where the rectified voltage Ei is low by the action of a second voltage detecting circuit 16 and the coil 4 is quickly excited.

IPC: E03F5/08
Filed: 1993-12-07
Abstract: PURPOSE:To make it possible to adjust the amount of sanitary sewage to be transferred by installing a sanitary sewage flow outlet and further installing a flow out quantity control device near the sanitary sewage flow outlet. CONSTITUTION:Sanitary sewage in a contact aeration tank A3 is arranged to rise in a rise pipe 1 by the supply of air from an air lift air supply pipe 2, thereby transferring the sanitary sewage to a first anaerobic filter bed tank A1 from a transfer line 5 by way of an Y-shaped line 4.
