Filed: 1986-06-05
Abstract: PURPOSE:To measure liquid absorption characteristics which affect the utilization and processing of various kinds of paper by heating and controlling a liquid storage tank which has a hole part at right angles to the rotational direction of a drum to optional temperature, and placing a proper load and taking a measurement while bringing the hole part into contact with the surface of paper stuck on the drum.

Title: Probe-driving apparatus for scanning tunneling microscope
Inventor: NAKAHARA MAKOTO
IPC: H01J37/28
Filed: 1991-05-31
Abstract: PURPOSE:To prevent the collision in rough action by making the amplification factor and the response frequency of a negative feedback amplifier variable or delaying the negative feedback of the detected signal of a tunnel current. CONSTITUTION:The specified amplification factor and response speed are set for a variable-amplification-factor/variable-response amplifier 4 through a CPU 1 based on the material and the surface state of a sample 11. A switch 6 is turned ON, and a micromotion mechanism 21 to which a probe 10 is attached is brought close to the sample 11. A tunnel current is made to flow through the probe 10 and amplified with an I/V AMP 3. The output is quickly amplified with the amplifier 4 and outputted to a signal delaying circuit 5. The output of the circuit 5 is outputted to a Z-piezoelectric element driver 7 through the switch 6. A voltage is applied on a Z-piezo-electric element 8. Thus the micromotion mechanism 21 is contained, and the probe 10 is separated from the sample 11 so as to avoid collision. Here, the CPU 1 which has detected the tunnel current through an A/D converter 2 stops the rough action mechanism. The response speed of the amplifier 4 is made slow, and the piezoelectric element 9 is driven. Thus the probe 10 is brought close to the sample 11.

Abstract: PURPOSE:To easily obtain a desired grading density in matching with the recording characteristics of a recording paper, by storing a signal corresponding to the recorded density in advance in a memory. CONSTITUTION:An analog signal to be recorded is applied from an input terminal 1 at a specified level and the inputted analog signal is sequentially converted into a digital signal with a clock of a specified frequency generating circuit 3 at an A-D cnverter 2.

Title: Multilayer flexible printed wiring board
Inventor: YOSHIDA MASATOSHI
IPC: H05K3/46
Filed: 1990-05-21
Abstract: PURPOSE:To sharply reduce a stress exerted on a wiring board main body by a repeated bending operation by a method wherein the number of integrally bonded conductor layers is set at two layers or lower and the length of parts which are not bonded and which are bent repeatedly is set at a prescribed value or higher. CONSTITUTION:At two double-sided FPC's 1, conductor patterns 3 are formed on insulating layers 6 to be used as inner layers and are covered with overlays 5. Then, terminal parts T of the two double-sided FPC's 1 and end parts on their opposite sides are laminated alternately via an interlayer adhesive 4. In this case, the length of unbonded parts of the double-sided FPC'c 1 is set to six times or higher the bending radius which is bent repeatedly. Then, holes are made in prescribed positions of the terminal parts T's; their inside is plated with copper; and copper through holes are formed. The outer-layer conductor patterns 3 are formed on both faces of the laminated body provided with the copper through holes; and after that, the overlays 5 are formed on the surface of the patterns 3. Thereby, since a stress acting on regions between bonded parts and the unbonded parts is made small, a repeatedly bending characteristic is excellent and connecting reliability can be enhanced.

The phase comparator PD 7 compares the leading phase of two input signals and outputs a signal in response to the phase difference. The output signal is converted into a DC voltage through a low pass filter 8 and impressed to a varactor of the oscillator 10, that is, the control terminal. Thus, the voltage controlled surface acoustic oscillator 10 is phase-locked always by the frequency accuracy of the standard radio wave JJY and is very stable.
