Title: Combustion apparatus
Inventor: TSURUTA TORU
IPC: F23N1/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To accurately detect any trouble of a gas solenoid valve during combustion other than the switching operation of combustion by determining a ratio between a necessary degree of combustion and an actual degree of combustion to judge a trouble of a solenoid valve detecting a sudden change in the value obtained. SOLUTION: A computation is performed to determine a ratio between a necessary degree of combustion computed based on a set temperature, the temperature of water fed and the amount of the water fed and an actual degree of combustion computed based on the temperature of delivered hot water, the temperature of water fed and the amount of the water fed and when sensors 35, 37, 39, 41, 43 and 45 detect any sudden change in the value computed, a trouble is determined to occur in any of solenoid valves 21, 23, 25 and 27. Therefore, even during combustion other than the operation of switching combustion, when a coil disconnection or the like causes a trouble in the gas solenoid valves 21, 23, 25 and 27 to be closed and when a fire is started in the course of some of burners 11, 13, 15 and 17 as well, correct judgment is possible.  When the closure of a heat exchanger causes abnormal combustion such as shortage of the amount of air, the value computed changes gradually thereby enabling judgment of the abnormal combustion being distinguished from other cases.

Filed: 1990-06-04
Abstract: PURPOSE:To reduce a collector current and to operate in high frequency with low power consumption by reducing the area of an active region of a collector layer smaller than that of a junction region between a base layer and an emitter layer. CONSTITUTION:A stripelike region 5 of a microscopic area such as 1X5mum of an n<-> type GaAs collector layer 4 is covered with a metal mask, the entire surface except the region 5 is ion implanted with H<+>, B<+>, O<+>, etc., to be inactivated, and formed with a P<+> type GaAs base layer 7. A part effectively operated as a collector region is limited to the region 5. A junction region between the layer 7 and an n<-> type AlGaAs emitter layer 8 is also mesa etched to miniaturize the area. That is, the synergistic effect of the facts that a part operated effectively as a collector region is limited to the region 5 and the area between the layer 7 and the layer 8 is miniaturized to miniaturize the area of the operating region, and a collector current can be reduced while a collector current density is maintained high.

IPC: B22D17/14
Filed: 1988-06-10
Abstract: PURPOSE:To inject molten metal into a casting cavity by the air permeated through the clearance between a plunger tip and a cylinder sleeve to prevent the quality of a die cast article from being deteriorated by providing the air- tight sealing member coming in close contact with the inner peripheral surface of the cylinder sleeve on the outer peripheral surface of the plunger tip for injecting the molten metal in a vacuum die casting machine. CONSTITUTION:The molten Al alloy, etc., in the cylinder sleeve 3 are cast under pressure through a runner 7 into the casting cavity 1 which is composed of a fixed die 2A and a movable die 2B and is provided with a vacuum vent 8. An annular groove 10A is provided on the outer peripheral surface of the end of the plunger tip 10 for extruding molten Al set on the tip of a piston 6 and a ringed air-tight sealing member 11 made of elastic material is fitted in the groove to keep the air-tightness between the inner peripheral surface of the injection cylinder sleeve 3 and the plunger tip. Since air does not come from the clearance between the plunger tip 10 and the cylinder sleeve 3, it is possible to prevent the deterioration of appearance and quality based on the injection of the molten Al alloy 3A into the cavity 1 and the generation of blow holes in the die cast article by permeation and expansion of the air.

Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To rationally perform the initializing operation of serial communication considering the recovery of a communication error even when the communication error is caused by initializing the serial communication in the case of deciding that a signal is an improper signal. SOLUTION: When the CPU 7 of a television lens 1 receives the signal from a television camera 2 through the serial communication 9, a timer is started. Circumstances that the signal is not inputted from the camera 2 (time out) are judged as an abnormal state, so that processing is shifted to reset processing routine. The reset processing routine is the first operation performed at the time of connecting the lens 1 and the camera 2. In order to recognize the equipment each other, the equipment is confirmed according to an initializing command or the like. When parity and check sum are improper, the processing is restored to the reset processing routine in the case of out-of-specification command. In the case of judging that it is a regulated command, the processing is shifted to a routine for interpreting and executing the command.

Abstract: PURPOSE:To reduce the dead space behind an equipment and allow the proper connection to connection terminals vertically aligned at the back by setting the angle between the axial direction of a connection member of a plug and the extending direction of a cord to an obtuse angle. CONSTITUTION:When the connection member 5 of a plug 3 is connected to a connection terminal 2 at the back of an electronic equipment, the angle between the axial direction 5a of the connection member 5 and the extending direction 9a of a cord 9 is set to an obtuse angle, thus the cord 9 extended backward is inclined.

Abstract: PURPOSE:To keep the gain variance of an equivalent transmitter within an optional range despite the fluctuation of number of working channels and to ensure an effective use of the electric power of the transmitter, by controlling with prescribed weighting the working point of the transmitter in response to the number of audio circuits. CONSTITUTION:A voice 1 is supplied by a voice activator VOX to a delay circuit 11 which prevents the erasion of the head voice part and then modulated by a modulator 31. The modulated voice is applied to a voice detector 21. The number of working channels is varied with the VOX action, and the output of the voice detector of each channel is fetched into a counter 11 to calculate the number of working channels. This calculated number of working channels is delivered to a controller 12. The controller 12 controls a high-speed variable attenuator 13 and then the working point of a transmitter 9. Thus the transmitter is actuated at an optimum working point in response to the number of working channels, and the electric power of the transmitter can be used with the highest efficiency.

IPC: H04W4/24
Filed: 1992-06-05
Abstract: PURPOSE:To suppress the call request at the time of a jam, to suppress the increase of the number of call channels by promoting the call request at the time of a non-jam and to enhance the ratio of signal to noise, by setting a call charging value according to the number of call channels. CONSTITUTION:When a base station 10 is busy in response to the call requests from moving equipments 11 to 13, the number of call channels is counted as 3. Call charging is set in accordance with this count value and this information is transmitted to a moving equipment in which a new call request occurs. The base station 10 divides the number of call channels in a limit where the influence by other channels is great and a call is impossible into plural stages, and determines the charging value for every stage. When a call request occurs from a moving equipment 14 as a moving equipment where a new call request occurs, the information on the charging value converted from the jam degree of the present call channel is transmitted to the moving equipment 14 and is transmitted to a user. The user judges whether the call request is continued or not from the charging value and transmits the result to the base station 10 via the moving equipment 14.
