Abstract: PURPOSE:To facilitate passing over an obstacle and other similar operations by  a method wherein driving wheels are attached to a vehicle through stretchable legs and the stretching amounts of the legs are regulated, in a vehicle traveling through passage where obstacles, stairs or the like are present. CONSTITUTION:Five strethcable legs 12 fitted with the driving wheels 13 are placed at positions corresponding to the apexes of a pentagon, and a main body 1 is supported by the legs 12. The legs 12 are so constructed as to transmit the rotation of a motor 37 to a nut 34 through gears 36, 35. The nut 34 is placed in a housing 39, which is fstened to the main body 40 by bolts through a bush 38. When passing over an obstacle, for example, first the legs 1, 3, 4 are simultaneously brought into contact with the obstacle, then the leg 1 is lifted and brought onto the obstacle, and other leg 4 is lifted. After causing the leg 4 to make a step, it is lowered to make an advance. Similarly, the legs 3, 4 are sequentially lifted and caused to make a step, whereby the main body 40 can be mounted on the obstacle. A descending motion is performed by actions reverse to the above.

Title: Pressure-sensitive conductive sensor
Inventor: YASUDA MASAO
IPC: H01H13/00
Filed: 1998-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain a pressure-sensitive conductive sensor which obtains a pressure-sensitive characteristic of high reliability without being influenced by dust particles and a small flaw on the surface when a comb-shaped electrode is coated with a pressure-sensitive composition, by a method wherein the region in a part of the comb-shaped electrode protrudes from the contact region of a pressure element with a pressure-sensitive conductive layer. SOLUTION: The region of a comb-shaped electrode 4 is coated with a pressure-sensitive conductive composition, and a pressure-sensitive conductive layer 3 is formed. The pressure- sensitive conductive layer 3 is formed to be of a structure which is not compressed so as to exceed, e.g. 30% of the layer 3. In this case, the height difference (b) in the outside-diameter end part 6, of a pressure element 1, as the contact face of the most protruding part 2 of the pressure element 1 with an electrode formation face 5 is formed to be about 70% of the layer 3. Consequently, when the pressure element 1 is pressed and when the most protruding part 2 presses 30% of the thickness of the pressure sensitive layer 3, the outside-diameter end part 6 of the pressure element 1 is grounded to, and stopped by, the electrode formation face 5, and its compression of more than that is limited.  As a result, since the pressure- sensitive conductive layer 3 is not exposed, it is not affected by dust particles. In addition, when the compression rate of the layer 3 is set to be withing 30%, The pressure-sensitive characteristic of a pressure-sensitive conductive sensor is not influenced even when a small flaw exists on the surface, and it is possible to obtain the high-reliability pressure sensitive property of the pressure-sensitive conductive sensor.

Title: Digital transmission method for voice signal by vocoder system
Inventor: YAGI SHINSUKE
IPC: G10L19/00
Filed: 1987-03-20
Abstract: PURPOSE:To prevent undesired voice from being given to other station by applying code conversion to coded data of a frame synchronizing signal and a voice signal for each frame and sending the result to apply communication to a desired party only. CONSTITUTION:A control circuit 21 outputs a SYNC 1 at the start of transmission and controls a synchronizing signal generator 20 and a switch 8 so as to insert a SYNC2 once to each M frame. A code converter 22 applies code conversion for each frame to transmission data according to a set conversion rule for each frame. A decoding circuit detects the SYNCs 1, 2 subjected to code conversion by the converting method assigned to its own station by a synchronizing signal detection circuit 23, the code converter 25 applies the inverse conversion to the assigned converting method to its own station to obtain original analysis data thereby synthesizing the voice. Thus, since no synchronizing signal is detected by other stations, that is, a receiver in standby state by a different converting method, the voice is not decoded.

Filed: 1993-03-23
Abstract: PURPOSE:To relatively easily and highly accurately measure thermal diffusivity of a thin sample having a constant thickness regardless of the thickness of sample or the frequency of AC heating power. CONSTITUTION:A sample 3 is sandwiched by first and second media 1, 2 one of which is made of the same material as the sample 3. AC power is then fed from an AC power supply comprising an oscillator 12 and a power amplifier 11 to a metal film resistor 4 for AC heating disposed on the surface of the sample 3 thus heating the sample 3. An AC temperature signal is then delivered from a metal film resistor 5 provided on the rear of the sample 3 to a lock-in amplifier 13. A personal computor 14 then determines a characteristic curve of phase difference between the AC power and the AC temperature signals of various frequencies outputted from the lock-in amplifier 13 having the root of the frequency of AC power as a variable. Thermal diffisivity is finally calculated from the gradient of the characteristic curve.
