Title: Method for controlling temperature of reformer
Inventor: SAITO HAJIME
IPC: C01B3/32
Filed: 1993-07-05
Abstract: PURPOSE:To reduce control delay and to prevent a combustion chamber and a reforming chamber from overheating by detecting temperature upstream of the combustion chamber using a temperature sensor, and controlling the flow rate of fuel gas in an auxiliary burning line so that the temperature detected is within a predetermined range. CONSTITUTION:A reformer 10 burns anode gas 4 from a fuel cell using cathode exhaust 7 and reforms fuel gas 1 into anode gas 2 by the heat of the burning. This device is provided with an auxiliary burning line 12 through which fuel gas is supplied to the exhaust 4 and an air line 14 through which low- temperature air is supplied to the exhaust 7. The line 12 is provided with a fuel flow control valve 13 for controlling the flow rate of fuel gas and the line 14 is provided with an air flow control valve 15 for controlling the flow rate of low-temperature air. The control valve 13 or 15 is controlled according to a temperature detected by a temperature sensor 16 for detecting temperature upstream of the combustion chamber of the reformer 10, so as to keep the upper portion of the combustion chamber at a predetermined temperature. Thereby control delay is reduced while the combustion chamber Co and a reforming chamber Re are prevented from overheating.

Filed: 1991-06-10
Abstract: PURPOSE:To realize the communication processing unit with excellent function performance in which the selection of a call mode or a reply message transmission mode is executed properly by counting a ring time of a call tone in the call mode. CONSTITUTION:When a call signal is sent to a telephone set 2 via a network 1 and a detection section 3 detects it, a main control section 4 checks a mode data of the telephone set 2. In the case of the reply message transmission mode, a reply message is outputted. Moreover, in the case of the call mode, a timer of a clock section 6 is started to check the presence of reception by the user and the processing is terminated through the reception. When the signal is not received, a timer count X is compared with a prescribed value X', and in the case of X<X', the presence of reception is continuously checked, and in the case of X>X', it is discriminated to be absent, and a changeover section 7 is used to select the reply message transmission mode from the call mode and a reply message is outputted, Thus, the selection of the call mode or the reply message transmission mode is executed properly.

Title: Digital signal processor
Inventor: HIROTA YUTAKA
IPC: H03H17/00
Filed: 1979-12-18
Abstract: PURPOSE:To enable to eliminate the folded noise produced at a digital attenuator effectively, by the decoding with higher frequency than the sampling frequency used in encoding. CONSTITUTION:When a digital signal encoded in sampling frequency fS is input to a digital attenuator, frequency components higher than fS/2 is produced at the output. In decoding this signal 18, side band waves 19 are produced up and down by taking the sampling frequency for decoding as the center. To avoid the production of folded noise between the side band waves and the signal 18 to be composite, the sampling frequency for decoding is taken sufficiently higher than the frequency used for coding.

Title: Oversampling d/a converter
Inventor: SAKIYAMA SHIRO
IPC: H03M3/02
Filed: 1995-06-30
Abstract: PURPOSE: To obtain a resistor ladder type oversampling D/A converter having high accuracy and yield without generating a glitch (a transiently generated noise). CONSTITUTION: A signal to be changed only by ±1 by one clock from an one-bit quantizer in an interpolation type modulation part 1 is used as a shift direction control signal. The control signal is applied to a bidirectional shift register 2. The register 2 shifts data to the prestage side or the post stage side based upon the value of the received shift direction control signal. An output from the register 2 is applied to a resistor ladder type D/A converter 3 as a control signal. The converter 3 outputs analog potential corresponding to a switch selected by the control signal. Thereby even when a delay difference is generated between respective bits, the output of the D/A converter 3 is continuously changed only by the double selection of adjacent switches.

IPC: C08K5/54
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To suppress the slip of an outsole of shoes on a wet floor surface by making an outsole out of a vulcanized molded product of a rubber composition that comprises a diene rubber containing a clay whose major component is kaolinite and a silane coupling agent in specified amounts respectively. SOLUTION: An outsole 2 is made out of a vulcanized molded product of a rubber composition comprising 100 pt.wt. diene rubber, 10 to 40 pts.wt. clay whose major component is kaloinite, and 0.1 to 15 pts.wt. so that the outsole 2 itself may be made water-repellent. If the content of the clay is less than 10 pts.wt. per 100 pts.wt. diene rubber, the effect of making the outsole water- repellent cannot be exhibited satisfactorily whereas if the content of the clay is less than 40 pts.wt. per 100 pts.wt. diene rubber, the tear strength and the like are lowered. Thus, an outsole of a shoe that is excellent in wet gripping properties on a wet floor surface and is hard to slip even on a wet floor surface can be obtained.

Abstract: PROBLEM TO BE SOLVED: To simplify structure and facilitate control, and at the same time to improve driving efficiency by allowing each displacement element to be subjected to resonance driving, so that a displacement synthesis part for synthesizing the displacement of each displacement element performs elliptical motion. SOLUTION: In the truss-type actuator, two displacement elements 10 and 10' are arranged so that they cross each other nearly orthogonally, and a chip member 20 is jointed to the end part at the cross side by an adhesive.
