Title: Stirling engine and start controlling method thereof
Inventor: KAWAMOTO HIROSHI
IPC: F02G1/043
Filed: 1993-03-15
Abstract: PURPOSE:To secure the quality of a heater pipe and assure a start by controlling the combustion quantity of a combustor for heating when the heater pipe transferring heat to a heat exchanger head section is heated to the prescribed temperature. CONSTITUTION:When a combustor 3 is ignited and an engine is kept in the cold state at the time of a start of a Stirling engine, a heater pipe 2 is heated by the first combustion quantity. When the temperature of the heater pipe 2 detected by a temperature detector 5 becomes a specific temperature, the combustion quantity is reduced by a specific quantity to heat the heater pipe 2. The same heating method is repeated while whether the temperature of a heat exchanger head section high-temperature side surface 1a detected by another temperature detector 6 reaches the start set temperature or not is judged. When this temperature reaches the set temperature, the operation of a starter 4 is activated. The quality of the heater pipe 2 is secured, and a sure start can be efficiently made.

Title: Picture signal recording and reproducing system
Inventor: OGURA SHIGEO
IPC: H04N5/92
Filed: 1990-03-07
Abstract: PURPOSE:To effectively use a recording medium when recording a high fidelity picture signal by controlling the number of tracks to be recorded to two corresponding to the high fidelity picture signals for one picture in respect to the respective surfaces of the recording medium. CONSTITUTION:A photographed image is guided through a photographing optical system 101 and a shutter 102 to the image pickup surface of an image pickup element 103. The signal to be outputted from the image pickup element 103 is processed by a signal processing circuit 104 and recorded to the back of a video floppy 109. In such a case, when recording the picture signals for one picture equipped with the second horizontal resolution higher than the first horizontal resolution, the picture signals are recorded by using an (n) pieces of recording tracks on the first surface of the recording medium, and an (m) pieces of recording tracks on the second surface different from the first surface of the recording medium. Thus, the amount of high fidelity signals to be recorded to the recording medium can be increased.

Title: Method and equipment for measuring poisson ratio
Inventor: NAGAKURA HIROSHI
IPC: G01N29/00
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To measure the Poisson ratio of a thin and long rod accurately, by finding the velocity ratio between low frequency and high frequency elastic waves propagating along a rod-like sample. SOLUTION: Samples 1a, 1b to be measured are made of the same material and have identical dimensions (length, diameter). A controller 14 commands a frequency generator 6 to generate a transmission signal of low frequency f1 . That signal is divided into two systems and one signal is subjected to voltage amplification through a transmission amplifier 7 and applied to a low frequency f1 transmitter 2 through the contacts a-b of a transmission signal switch 8 while the other signal is inputted to a transmission A/D converter 11. An elastic wave propagated through the sample 1a is passed from a low frequency f1 receiver 3 through a receiving signal switch 9 to a receiving amplifier 10 where it is subjected to voltage amplification. A branched transmission signal and a receiving signal are digitized, respectively, through A/D converters 11, 12 and inputted to a signal processor 13.  Similarly, a high frequency f2 signal is transmitted on a high frequency path and inputted to the signal processor 13. Subsequently, elastic wave velocities C1 , C2 are determined through correlation and the Poisson ratio is found from the velocity ratio.
