Title: Material for thermistor
Inventor: SUZUKI TOMONOBU
IPC: C04B35/00
Filed: 1987-05-22
Abstract: PURPOSE:To obtain a highly sensitive thermistor without lowering a constant B even in a compact, chip like thermistor where a low resistivity value is required by adding specified quantities of rare earth elements to oxides of a manganese-cobalt-nickel series. CONSTITUTION:To a manganese-cobalt-nickel oxide 1-10 wt.% rare earth elements are added. When an added quantity of the rare earth elements is within the range of 1-10 wt.%, an increase of a resistivity value is limited to that in a range of the practical use, although a constant B increases drastically. When the added quantity of them is less than 1 wt.%, the constant B does not increase very much and it makes little difference whether the rare earth elements are added or not. Yet, once the added quantity exceeds 10 wt.%, the resistivity value will increase extremely and such a resistivity is not suitable for the practical use as a thermistor.

Title: Logical connection method for plural devices to parallel port
Inventor: COX DARRELL L
IPC: G06F13/14
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a method which can logically connect a host computer to plural devices via a parallel port. SOLUTION: The EPA(extension port address) assignment is identical to a physical link layer communication protocol related to the mention of devices 102, 103 and 104 which are attached to the same parallel port of a desktop personal computer 101. In an EPA, the individual devices 102 to 104 are automatically decided when they are added to or removed from the parallel port. Then any device driver can apply the time division to a specific device driver without locking a logical port in the EPA. Also in the EPA, the plug-and-play characteristic is expanded by deciding whether the same parallel port should be shared when other devices are attached to the T box EPA devices 105 and 106.
Patent JP-H0423513-A (JP)
Title: Switch circuit
Inventor: NODA MASARU
IPC: H03K17/60
Filed: 1990-05-18
Abstract: PURPOSE:To reduce a potential offset between an input/output, to reduce the leak of a control signal and to raise the ability of a load current by controlling interruptedly the currents of both a suction current source and a source current source at the same time according to the control signal. CONSTITUTION:The currents of both a suction current source 5 and a source current source 6 are controlled interruptedly by the control signal applied to a control signal terminal 3. While the control signal indicates a switch-on, these two current sources 5 and 6 send equivalent currents. At that time, both of each transistor Q2 and Q4 connected by a diode are conducted and the signal added to a terminal 1 is transmitted through the two paths to an output terminal 2. While the control signal indicates a switch-off, these two current sources 5 and 6 stops sending the currents. At that time, entire transistors Q1-Q4 are cut off so that the input signal can not be transmitted to the output terminal 2. Thus, it is possible to obtain a switch circuit in which the potential offset between the input/output and the leak of the control signal are reduced and in which the ability of the load current is raised.

CONSTITUTION:The composite signal is inputted from a terminal 11 and is applied to resistance attenuators 12 and 12' which divide the voltage to 2N-number of stages, and outputs attenuated in many stages are outputted to analog switches 13 and 13'. These signals are switched successively through switches 13 and 13' controlled by a timing signal, which is generated by a timing signal generator 18 on a basis of a timing reference signal generator 19 having 2N-fold frequency of the carrier wave of the composite signal, and are outputted to buffer amplifiers 14 and 14'. Outputs of amplifiers 14 and 14' are taken out as right and left sound signals from output terminals 16 and 16' through LPFs 15 and 15'. In this case, the switch 13 is switched to outputs of the attenuator 12 in order from the output of the smallest attenuation quantity and is next switched to them in order from the output of the largest attenuation quantity by the timing signal of the timing signal generator 18, and the switch 13' is switched to those of the attenuator 12' in order from the output of the largest attenuation quantity and is next switched to them in order from the output of the smallest attenuation quantity similarly, and this operation is repeated with the carrier frequency of the composite signal.

Filed: 1993-05-28
Abstract: PURPOSE:To control the production of NOx without enlarging a combustion chamber by providing a part large in passing resistance in the longitudinally central part of a burner in a combustion device in which liquid fuel is gasified by a carburetor and burnt by the burner. CONSTITUTION:A combustion chamber includes a carburetor 10, a mixing space 20 and a burner 30. The burner 30 is provided with a pressure regulating chamber 31 and a burner plate 62. On the burner plate 62, many flame holes 621 and 622 are opened at a specific interval on an entire surface. The aperture D1 of the flame hole 621 is smaller than the aperture D2 of the flame holes located at both end sides. Accordingly, an aperture area at a central part is smaller than that at both end sides. Passing resistance at the central part is larger than that at both the end sides. When a combustion flame F comes into contact with a secondary air E for combustion so that it becomes an oxidizing flame, the blowout amount of mixed gas C in the flame hole 621 is smaller than that in the flame hole 622, since the aperture has such a relation as D1>D2 Thus, the combustion flame F is completely housed 10 a combustion chamber 50 and the production of NOx due to the abrupt oxidation of nitrogen monoxide in exhaust gas can be controlled.

Abstract: PURPOSE:To provide a tuning system capable of accelerating automatic searching. CONSTITUTION:This system is equipped with a radio part 1 which receives a wave, and a display part 2 which displays the frequency of the wave received by the radio part 1. The system is constituted in such a way that the frequency varied continuously when an automatic searching operation to search the wave emitted from a broadcast station is performed as varying the frequency to be received by the radio part 1 continuously can be displayed by transferring to the display part 2 only when the frequency varied continuously coincides with the frequency of the wave emitted from the broadcast station.

Filed: 1986-06-03
Abstract: PURPOSE:To speed up the rise of system operation by determining whether initial program loading (IPL) from a master station to a slave station is to be executed or not in accordance with the existence of damage of the contents of a main storage device. CONSTITUTION:At the time of turning on the power supply of a system, a CPU 1 reads out the existence of a voltage drop signal 1. When the signal 11 is significant, i.e. the voltage of a battery 10 is <= a set point, the contents of the main storage device 2 are regarded as damaged ones and an IPL request is outputted to a master station device 6 in the master station A to execute IPL from the master station A to the device 2. When the signal 11 is insignificant, i.e. the voltage of the battery 10 is >= the set point, there is no memory damage and the program of the slave station B is left as it is, so that the program is immediately started without outputting the IPL request to the master station A. Thereby, time required for IPL can be omitted and the system operation of a network system can be immediately attained.
