Title: Output power amplifier for transmitter
Inventor: MATSUI YASUSHI
IPC: H03F1/30
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To stabilize the output power of a transmitter under an environment where temperature fluctuation is large by adding a temperature compensating circuit for varying an output power reference signal in accordance with the temperature fluctuation of the detected output from a detecting circuit. SOLUTION: Even when one part of the same transmission power is separated and outputted by a directional coupler 3, an output voltage is increased when temperature is increased in a detector circuit 4, and when a temperature compensating circuit 7 is not present, it is judged that the output of a transmitter is equivalently high in a comparison error amplifier 5, and the output power of the transmitter is controlled so as to be decreased. Then, the temperature compensating circuit 7 is provided for compensating temperature characteristics. As the characteristics of this temperature compensating circuit 7, an output power reference voltage signal 6 to be inputted to the comparison error amplifier 5 is changed by considering the characteristics of the detector circuit 4. Therefore, when the temperature is increased, this output power reference voltage is increased so that the output power of the transmitter can be prevented from being decreased, and when temperature is decreased, this output power reference voltage is decreased so that the output power can be prevented from being increased.

Title: Copper alloy matrix wear resistant composite material and its production
Inventor: TANAKA TORU
IPC: C22C47/00
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To improve the wear resistance of a composite material and to reduce its mating attackability by using aluminum borate whiskers as a reinforcing material and using a copper alloy as a matrix. SOLUTION: In this composite material, as a reinforcing material, aluminum borate whiskers softer than SiC particles and hardly causing the falling from the matrix are used. The volume content thereof is regulated to 30 to 35% from the viewpoints of reinforcing performance and the impregnation of the matrix. On the other hand, as the matrix, in order to improve the wear resistance of the composite material, a copper alloy having high hardness is used instead of an Al alloy. However, since the conventional copper alloy prescribed in JIS, is too high in m.p. and difficult to be used for the matrix, the copper alloy added with the following elements by suitable amounts is used. Namely, 15 to 25wt.% Sn, <=10wt.% Si, <=5wt.% Mn, <=5wt.% Zn and <=2wt.% P are added, and the copper alloy having the m.p. close to that of an Al alloy and furthermore increased in hardness is used.

Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a ventilating fan and an illumination switch circuit which can enhance controllability, meet the demand for power savings, and ventilate sufficiently. SOLUTION: When a switch knob is set at a first position, only a first switch 12a is turned on and only a ventilating fan 16 is driven. When the switch knob is set at a second position, the first switch 12a and a second switch 12b are turned on, the ventilating fan 16 is driven, and an illumination 18 is turned on. When the switch knob is returned from the first or second position to a neutral position, the second switch 12b is immediately turned off, while the first switch 12a is turned off after the elapse of a predetermined time by the action of a retarding mechanism 24. Therefore, while the illumination 18 is immediately turned off, the ventilating fan 16 is stopped after being driven for a predetermined time. Thus, operations are simple, the demand for energy savings can be met, and sufficient ventilation can be provided.

Title: ROAD SURFACE mu DETERMINATION METHOD IN VEHICLE
Inventor: NISHIZAWA HIROMITSU
IPC: B60T8/26
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To quickly determine a road surface μ by determining existence/ absence of a longitudinal shift of a load when a brake pedal is actuated and determining height of the road surface. SOLUTION: Actuation of a brake pedal is detected by means of a brake switch 32. In this case, if a determined road surface μ is high, a great braking force is applied to a vehicle in actuation of the brake pedal as frictional resistance of the road surface is high. Consequently, a vehicle load is shifted forward by inertia force. If the determined road surface μ is low, a braking force is hardly applied to the vehicle in actuation of the brake pedal because frictional resistance on the road surface is low, so that a vehicle load is hardly moved forward by inertia force. In this way, when a longitudinal shift of a vehicle load is measured by a wheel side sensor 31, a dimension of the road surface μcan be determined quickly.

Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To prolong the life of the filter of a org. metal vapor growth apparatus having the filter for filtering exhaust gase by forming the filter as a vertical type and disposing a heat exchanger for cooling the exhaust gase between a reaction furnace and the filter. SOLUTION: This apparatus consists of a cylinder having a jacket to pass cooling water to the outer side on the downstream side of the exhaust gases of the discharge port 3 of the reaction furnace 1 and has the heat exchanger 8 for cooling the exhaust gases which is constituted by packing stainless steel fibers therein in order to enhance heat exchange efficiently. The exhaust gas outlet side of the heat exchanger 8 is provided with the filter 10 of the vertical placement type formed by concentrically and vertically arranging four pieces of filter materials into a cylindrical trap vessel. When the exhaust gases pass the filter materials from the outer side to the inner side, the decomposition products in the exhaust gases deposit on the filter surface but when the deposits grow large, the deposits are peeled by their own weight and are dropped.  The dropped deposits accumulate in the trap vessel. Since there is no need for exchanging the filter materials until the vessel is filled with the deposits and therefore, the life of the filter materials is prolonged.

Abstract: PURPOSE:To suppress spurious vibration and to decrease the dispersion in the characteristic due to the deviation of position of an energy confinement electrode by designing the size of at least one of outermost layer electrodes among energy confinement electrodes larger than that of the energy confinement electrode placing in the inside. CONSTITUTION:At least the shape of one of the energy confinement electrodes 13, 16 at the outermost layer in the broadwise direction is designed as a circular or a polygon, and the diameter or the length of one side is made larger than that of the internal circular or polygonal energy confinement electrode 15. Thus, the deterioration in the accuracy of overlap with respect to the outer energy confinement electrodes 13, 16 whose diameter or length of one side is relatively made longer than that of the electrode 15 is not caused. That is, the allowable amount of the location of the electrode, 15 with respect to the energy confinement electrodes 13, 16 at the outermost layer is improved by increasing the size of the outer energy confinement electrodes 13, 18 relatively. Thus, the dispersion in the resonance characteristic and the production of spurious radiation due to the deviation of the position between the overlapped electrodes are suppressed.
