Title: Ultrasonic motor
Inventor: KUWABARA SHIGEO
IPC: H02N2/00
Filed: 1990-01-19
Abstract: PURPOSE:To attain highly-efficient and stable rotation and to obtain an ultrasonic motor being economical by supplying a power to one of two piezoelectric elements and by making the other non-electrified by short-circuiting positive and negative poles. CONSTITUTION:When a pulse-shaped high-frequency voltage E is impressed only on the A side, a piezoelectric element 1-a extends in the vertical direction and makes displacement. This displacement is propagated as a wave motion to a driving body 1-b and proceeds as a longitudinal wave downward. Striking on a surface cut down at an angle of 45 degrees, this wave-motion propagation is reflected 100 percent substantially when there is much difference in an acoustic impedance from a medium being in contact with this surface, for the existence of the medium is neglected. Then the longitudinal wave Y' and the wave motion intersect each other at a right angle, the resultant wave motion becomes an elliptic motion having a vector velocity, and a differential displacement directed from the right to the left occurs in a pulse cycle of a power source in the portion of a fore end face 1-b'''. Thereby a rotary drum 2 rotates counterclockwise.

Title: Starting carburetor for internal combustion engine
Inventor: IKEDA AKIRA
IPC: F02M1/04
Filed: 1979-02-01
Abstract: PURPOSE: To improve starting performance by a method wherein the flat chamber of the main carburetor and the main well of the starting carburetor are connected through a plural number of starter jets, and the starter jets are made to make-and- break according to the intake temperature.  
     CONSTITUTION: As bimetal vacuum switch valve (BVSV) is open at a low temperature, the negative pressure extends to the air chamber 19 of the siaphragm unit D through a connecting pipe 22 and the diaphragm 16 is attracted to the air chamber 19 side so that the make-and-break valve 15 opens the fuel pipe 14. Therefore when the engine starts, the fuel in the float chamber 8 is fed into the main well 9 being devided flowing through two starter jets 12, 13. On the other hand, when the engine temperature rises up to the BVSV set value, it is closed to take the air into the air chamber 19 through a small hole 20. Consequently the spring 21 moves in pushing the diaphragm 16 making the make-and-break valve 15 to close the fuel pipe 14 and to limit a fuel flux to one starter jet 12.

Title: Sweep control method of luminous analyzing spectroscope using microcomputer
Inventor: SUZUKI NORITO
IPC: G01N21/67
Filed: 1980-01-31
Abstract: PURPOSE:To calibrate automatically all fluctuation factors of a spectroscope and to make corrections upon occasion by using a microcomputer. CONSTITUTION:A monochromator driven by a step motor is used to convert wavelengths of several spectral beams into the numbers of steps, which are stored in the memory of a computer; a high-speed wavelength sweep is done in the region other than that of the spectral beams and a low-speed wavelength sweep is done near an assigned spectral beam. In the low-speed wavelength sweep region, the peak of the spectral beam is detected and the difference between its position and an assigned position is used to correct the number of steps in the memory; and a shift to the position of the next spectral beam is made and the number of steps in the memory is similarly corrected. Said operation is repeated successively and on the completion of one sweep, the corrected numbers of steps are used to take a backward sweep until the initial spectral beam.

Title: Communication network controller
Inventor: ADACHI OSAMU
IPC: H04L69/40
Filed: 1991-01-08
Abstract: PURPOSE:To prevent missing of a frame due to occurrence of collision by devising the controller such that a MAC frame sent from a terminal equipment for the purpose of ring management is not sent to an indefinite communication network. CONSTITUTION:An input signal from a TRN terminal equipment is given to an input signal identification section, in which a free token and a frame are identified and further a MAC frame is identified. The frame is written in an FIFO 6 but the MAC frame is written while being distinguished from other frames. The other frames are outputted to an indefinite communication network 3 as a conventional method. The MAC frame written in the FIFO 6 is immediately read and then stored to the FIFO 8 tentatively while being distinguished from other frames. Although an OR gate 17 is shown in figure as a simplified expression, when the MAC frame is written in the FIFO 8, it is written with higher priority than that of the input frame from the indefinite communication network 3. Thus, the MAC frame is read from the FIFO 8 and looped back to the TRN terminal equipment 1 via an output selector 13 and not outputted to the indefinite communication network 3.
