Title: Method for adjusting combustible component content of gas in coke dry quenching equipment
Inventor: UCHIDA TETSUO
IPC: C10B39/02
Filed: 1988-10-28
Abstract: PURPOSE:To prevent the variation of the calorific value of gas and to improve the combustion efficiency by estimating the variation of either the combustible component content of circulating gas or the calorific value of the gas based on the coke charge schedule, and performing a specified control depending upon a deviation from a set value. CONSTITUTION:A cooling tower constituted of a prechamber 1, a cooling chamber 2, and a cutting and discharging device 3 receives red-hot coke from the top, cools it, and discharges it from the bottom. Cooling gas is passed through a boiler 20 for heat recovery, while feed water 8 is fed into the boiler 20 to generate steam 7. The cooling gas is circulated by a circulating fan through the cooling tower. The composition of the circulating gas is determined by anylysis with a gas composition analyzer 12 and, depending upon the analytical value, an air flow control damper 6 at the air intake fan outlet is regulated. An input air flowmeter 13 measures the flow rate of the air. This method for adjustment of gas composition serves to prevent the variation of the calorific value of gas when coke is fed into coke dry quenching equipment. Since the gas has neither extraordinarily high nor extraordinarily low calorific value, combustion control can be facilitated when the surplus gas in the circulating system is recovered for utilization, and combustion efficiency can be improved.

The output of the filter 5 is inputted to a PLL circuit 9 via an amplification slope 7 and a comparator 8. A signal with a frequency that is proportional to a velocity is outputted at a digital output terminal 10 of the PLL circuit 9 and an analog voltage is outputted to an analog output terminal 13.  An output terminal 10 is connected to the input terminal of a counter 11, pulses are added as a distance increment by utilizing each pulse of the digital output signal of the PLL, and an aim for advanced distance is displayed 12.

Title: Tone detecting method
Inventor: SATOYOSHI YOKO
IPC: H04M11/00
Filed: 1988-10-27
Abstract: PURPOSE:To rapidly detect the indetectable state of a second dial tone by prohibiting the detection of the second dial tone when no change occurs in a call progress tone detecting flag within a constant time. CONSTITUTION:When the off-hook of the telephone set of a user terminal is performed by a user, a dial tone DT is sent from a telephone network, and the user, after confirming the dial tone, dials a specific number 166 decided by a video tex communication system. In such a case, a busy tone BT is returned from the telephone network when a line is filled. When the second dial tone(SDT) is detected, it is detected whether or not the call progress tone detecting flag changes within the constant time longer than the cycle of the call progress tone detecting flag at the time of inputting the STD. As a result, when the change of the flag is detected within the constant time, the input of the SDT is detected only when the number of times of change is equal to the preset number of times, and when no change occurs within the constant time, the detection of the SDT is prohibited. In such a way, it is possible to rapidly detect the indetectable state of the SDT.

Title: Engine control device
Inventor: KAMATA YASUICHI
IPC: F02D41/22
Filed: 1988-10-27
Abstract: PURPOSE:To detect overspeed of an engine to cope with trouble even when an engine speed sensor fails by converting an output current of a generator driven by the engine into a voltage, comparing the voltage to a reference voltage, and thereby detecting the rotating state of the engine. CONSTITUTION:An engine E is rotated in accordance with the amount of fuel supplied from a fuel supply device 3 to drive a generator G. In this instance, a current detecting unit 7 detects an output current of the generator G to input a detection signal to a comparison unit 4 through a conversion unit 5. At the same time an engine speed detecting unit S detects engine speed of the engine E to input a detection signal to a comparison unit 1. When the engine E rotates at overspeeds, the output current of the generator G increases, output voltage Va of the conversion unit 5 exceeds a reference voltage V, the comparison unit 4 outputs a drive-stop signal to a drive unit 2. The drive unit 2 thus stops fuel supply from the fuel supply unit 3 to the engine E regardless of control data from the comparison unit 1.

Title: Hologram scanner
Inventor: UEDA TETSUYUKI
IPC: G02B26/10
Filed: 1990-10-09
Abstract: PURPOSE:To obtain a prescribed Ftheta characteristic (an uniform speed characteristic) and to attain miniaturization of the hologram scanner by optically scanning a scanning surface through the use of light beams turned back/reflected plural times by means of plural reflecting mirrors. CONSTITUTION:When light beams 21 from a semiconductor laser are made incident on a hologram 14a, light beams 22 as first-order or higher-order diffracted light beams are projected toward a reflecting mirror 15. The light beams 22 are reflected by reflecting mirrors 15 - 17, and then reflected by the reflecting mirror 16, again, and turned into light beams 26 for scanning. The reflecting mirrors 15 - 17 are extended in respective deflecting directions of the reflecting mirrors 15 - 17, so that they cover the light beams deflected accompanying with the rotational action of a hologram disc 14. Therefore, the light beams 26 after being turned back and reflected plural times like this, form an image on a photosensitive drum, as the light beams for scanning, and simultaneously, carry out main scanning on the photosensitive drum accompanying with the rotational action of the disc 14. Thus, a hologram scanner which has the prescribed Ftheta characteristic and can be miniaturized, can be obtained.

Thus, even when the motor M is rotated in the directions of +D and -D, the rotation driving force is transmitted to the gear 37 of the feeding part 3 form the motor M through a fixed gear 43 and the gear 46 in either case. Besides, the action executed on the feeding part 3 side is similarly executed on the read part 2 side.

Title: Magnetic head
Inventor: NAKADA KAZUHIKO
IPC: G11B5/60
Filed: 1988-10-28
Abstract: PURPOSE:To improve the contact performance between a disk and the magnetic gap part of a magnetic head by using two slider surfaces set on the upstream side to suppress the fluttering of the disk. CONSTITUTION:A magnetic head 1 touches the recording surface of a disk through three slider surfaces 2, 3 and 4. At the same time, the head 1 is supported by a spring member like a gimbal plate, a plate spring, etc., at the side of the bottom surface 7. As a result, the head 1 rubs the disk with the constant contact pressure. In such a case, the surface 4 having a read/write magnetic gap 6 is set approximately at the center between other surfaces 2 and 3 and at the same time at the downstream side in the disk flow-in direction X to both surfaces 2 and 3. Thus the fluttering, etc., of the disk can be suppressed by the surfaces 2 and 3 before reaching the surface 4 having the gap 6. As a result, the contact performance is improved between the head 1 and the disk at the magnetic gap part.

Title: Electromagnetic relay
Inventor: KOJIMA KATSUTO
IPC: H01H51/24
Filed: 1988-10-31
Abstract: PURPOSE:To reduce abrasion of a card with respect to a stud so as to enhance contact reliability by providing, in the card abutted position of a movable contact spring, a pair of wings stuck onto the opposite side of the card abutted position in a widthwise direction of the contact spring. CONSTITUTION:A pair of wings 23b are projected widthwisely on a movable contact spring 23 at a contact position 23a to a card 8. The wing 23b is slightly bent in a direction opposed to the stud 8a of the card 8, and the surface thereof is stuck to the stud 8a. Accordingly, in switching a contact, when the card 8 is moved so that the stud 8a is brought into contact with a contact spring 23, the card 8 is abutted against the rounded surface of the wing 23b, and as a result, any chipping off by a rectangular edge is not generated as in a conventional relay. Therefore, abrasion in the card can be reduced, and thus, an electromagnetic relay having operational stability and high contact reliability can be obtained.
