Title: Suspension device for automobile
Inventor: YAMAMOTO TADANOBU
IPC: B60G17/00
Filed: 1986-12-06
Abstract: PURPOSE:To prevent a variation to the understeer side at the time of turning from occurring, by setting a suspension characteristic to that state that only one side of front and rear wheels is made into hard from softness in both of these front and rear wheels when a turning state is detected and the making the rest also to be turned to the hard. CONSTITUTION:A steering angle theta being shown by an output signal B out of a steering angle sensor 13 and a car speed V being shown by an output signal C out of a car speed sensor 14 both are inputted into a controller 12 which outputs a hard selector signal A1 to step motors 81 and 81 of suspensions 3 and 3 for front wheels 1 and 1 and solenoid valves 111 and 111 when it detects a fact that lateral acceleration G of more than the specified value has worked there from the steering angle theta and the car speed V, making each suspension characteristic of these front wheels 1 and 1 into hard. After the elapse of the setting time of a timer (unillustrated herein), it outputs a hard selector signal A2 to rear wheels 2 and 2, operating step motors 82 and 82 and solenoid valves 112 and 112, thus each suspension characteristic of these rear wheels is also made into hard. With this constitution aforesaid, at the time of turning, such a trend that it comes to the understeer side is checked, thus turning steerability is improvable.

Title: Laser trimmed resistor device and production thereof
Inventor: BUDNAITIS JOHN J
IPC: H01C17/00
Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To obtain a higher resistance by reducing the width of a conductive passage specifically through laser trimming of a resistance element. SOLUTION: A laser trimmed resistor 320 comprises two copper contacts 322 and a laser trimmed resistance element 324. The element 324 is formed by subjecting a resistance material to laser trimming 326 several times. Residual resistance material 328 is isolated from an electric passage between the contacts 322. Since the resistance depends on the size and profile of the element 324, a high resistance is attained. When an untrimmed resistance element of 400 μm width is provided, a conductive passage of 10-100 μm wide is formed, and that width corresponds to 2.5-25% that of the untrimmed resistance element. A resistance element which is as narrow in conductive passage as 200 μm corresponds to 5-50% that of the untrimmed resistance element.

Title: Flat cathode-ray tube
Inventor: IKETA SHUNICHI
IPC: H01J31/12
Filed: 1990-10-29
Abstract: PURPOSE:To better image reproducibility so as to enhance reliability by assembling an integrated unit into a storage container from the opening of the storage container, and locating a screen glass at the opening. CONSTITUTION:An insulator 5 is used for integrating a screen glass 3 and a cathode portion 2 together and the potential of the cathode portion 2 is isolated from that of the fluorescent material layer 4 of the glass 3. After exposure a jig used for exposure is removed from the insulator 5 and a base 7 having the cathode portion 2 provided on the upper surface thereof is mounted on the insulator 5 while being opposite to the glass 3, to provide a desired unit. The unit is assembled into a storage container 1 through the opening of the storage container 1 from the side of the cathode portion 2 and the glass 3 is located at the opening. Since those components are assembled into a unit, dispersion in final products is reduced so as to enhance reliability even with relatively rough accuracy in assembling. Because the fluorescent material layer 4 is formed by exposure means, image reproducibility is also bettered.

Title: 2-head optical disk device
Inventor: NISHINOMIYA MASANOBU
IPC: G11B7/085
Filed: 1986-12-09
Abstract: PURPOSE:To shorten a recording time by providing the titled device with a 1st arm whose one end is pivoted to a 1st head and the other end is pivoted to a movable member, and a 2nd arm whose one end is pivoted to a 2nd head and the other end is pivoted to the movable member, then making the 1st and 2nd arms the same in length. CONSTITUTION:A 1st arm 44R has the same length as a 2nd arm 44L and both ends of each are equal in pivoting position and interval. Therefore, 1st and 2nd heads 20R and 20L move close to or away from each other on the same radius of a recording medium 12 via a link mechanism when a bobbin 42 is moved toward a 2nd straight line after drive of a linear motor. Then the light spot sent from the head 20L scans the same information track on the medium 12 with a delay of a half round against the light spot sent from the head 20R. Thus it is possible for a postscript type recording medium to reproduce the recorded data by the head 20L to confirm whether the data is recorded correctly or not right after the data is recorded by the head 20R. Then the recording and reproducing actions are simultaneously performed in a simple way.

Title: Heat exchanger and operating method thereof
Inventor: ONISHI TOSHIO
IPC: C21D9/56
Filed: 1990-10-30
Abstract: PURPOSE:To allow a high degree of heat exchange in spite of meandering of a steel strip by constituting a resonance tube having a low-frequency oscillator in such a manner that its nodal plate can be displaced at the time of passing the steel strip in this resonance tube and heating or cooling the steel strip with excellent efficiency by the resonance vibration of gas as a heat medium in the resonance tube. CONSTITUTION:A heat transfer chamber 3 is formed of heat transmission media 5, 5 in the intermediate part of the looped resonance tube 2 which communicates with the apertures on both sides of the oscillator 1 for low-frequency sound waves and has the length of half the wavelength of the low-frequency sound waves and the steel strip S which is to be treated and is to be heated or cooled by being passed through the aperture 4 thereof. The gas in the resonance tube 2 is resonated at the vibration frequencies of the low-frequency oscillator 1 and the heat exchange between the steel strip S and the heat transfer media 5 is effected with high efficiency. The nodal plate 6 forming the node of the resonance low frequencies generated in the resonance tube 2 is so formed that the plate can be displaced. The heat exchange by the resonance vibrating gas between the steel strip S and the heat transfer media 5 is thus uniformly effected at the high degree by moving the position of the nodal plate 6 even if the steel strip S meanders.

Filed: 1990-10-30
Abstract: PURPOSE:To prevent the increase of a power consumption with simple constitution by equipping a pMOS transistor to a multiplexer, and providing a voltage correcting circuit connecting the source of this pMOS transistor to a positive supply voltage, a drain to a common line, and a gate to the inversion output of the common line. CONSTITUTION:The voltage correcting circuit is constituted by connecting the source of a pMOS transistor 8 for a pullup to a voltage Vcc, the drain to a common line 7, and the gate to the output of a cMOS inverter 5 respectively. Now, when the common line 7 goes to an H level, the gate of the pMOS transistor 8 for the pullup goes to an L level by the inverter 5, and goes to the voltage exceeding a Vth at a negative to the source, so the line is conducted and the voltage of the common line is increased to the Vcc by a drain current. Thus, the load pMOS transistor of the cMOS inverter 5 whose gate voltage goes to the Vcc is interrupted, and a stationary current does not flow to the cMOS inverter 5.
